We are looking at using your product in a CDMA environment and had the following questions: 1. I assume we will need a 1X card instead of a GSM modem for this purpose. I was told that your product has been tested with Sierra Wireless Aircards. We are planning on using a Verizon Sierra Wireless Aircard 555. Any ideas if your product is compatible with this? 2. Looking through the posts on your dicussion board, I came across the following paragraph posted by Bryce Norwood: "There is no standard for AT commands for sending SMS in the CDMA environment. Therefore we are only able to use a GSM modem for sending messages. " Does this mean that CDMA SMS and MMS testing is only possible with GSM modems?! If so, how does that work? We don't want to rely on inter-carrier agreements b/w operators for MMS transactions b/w GSM and CDMA networks. 3. Can you please clarify whether doing MMS in a CDMA network using your product is still only possible by having direct SMPP connection to operator's network? I understand that for WAP Push this would be required. Our assumption until now was that for SMS and MMS, your app would allow us to simulate P2P messaging from a PC, i.e using the modem/aircard we'd bypass direct connection to operator infrastructure. | |||

Hi Leila, I apologise for not replying to your question earlier. Let me answer your questions in reverse order, as it is easier to explain in that order: 3. To perform as a direct delivery MMSC in a CDMA environment, we need to have an SMPP connection to the operator's network ... or a connection to the operator's WAP Push Proxy Gateway. Basically, in CDMA environments, special attributes need to be set when sending out MMS notifications via SMS ... attributes which cannot be set when sending via a CDMA modem. This is further complicated by the fact that CDMA modems generally don't have any support for sending binary SMS messages. Generally, they only support sending text SMS messages ... but a binary SMS message is needed for the MMS delivery process. Now SMS/MMS does also support connections to an operator MMSC for sending messages, where we support MM7, MM4, MM1 and EAIF. One interesting feature for an operator MMSC connection is the MM1 connections. In a GPRS environment, NowSMS can dial-up a GPRS connection, and then send/receive MMS messages via the operator MMSC, just as the MMS client software on the actual mobile phone would. But that is tougher on a CDMA environment. On a CDMA environment, you could send (not receive) MMS messages over a CDMA modem, but that would require some more involved setup and knowledge about the operator's settings (which are frequently more hidden in CDMA environments). Basically, you would need to configure a dial-up networking profile in Windows which connected to the operator's network. Usually there is a short code that gets dialed. Then you configure "MMSC Routing" in NowSMS to use an MM1 connection using the "Dial-up:" profile that you created. There you will need to supply the IP address of the operator's WAP gateway that is used for MMS transactions, and the MMS server URL. Technically this is all possible, but note that I've never done this bit in a CDMA environment. 2. Correct. If you are aware of a CDMA modem that supports binary SMS message sending, I would be interested to learn more about it. But unfortunately, all of the specs that I have seen for such modems have only supported text SMS message sending. (And even if you could find one that supported binary SMS message sending, I am not optimistic that it would allow enough control over some low-level parameters that need to be set.) 1. Although I have not tried it, based upon specifications, I am fairly certain that it is not compatible. | |||

Bruce, Lets say I have access to Verizon's PPG. Do I use this configuration? http://www.nowsms.com/support/bulletins/tb-nowsms-007.htm When I set this delivery type in MMS Outbound Routing do I use? MM1, Direct Delivery, Convert to multimedia wap push? IF MM1 --> Server address is the PPG address? I then go to the web interface section called "Send MMS Message" Do I then go typing in the phone number " WAPPUSH=PhoneNumber/TYPE=PLMN@domain”, where “PhoneNumber” will contain the phone number of the push recipient? Or do I send from somewhere else? | |||

Yes, that link describes what you would do. Basically, instead of sending a WAP push over SMS, this causes NowSMS to send the push through a PPG. If you are sending an MMS message, the first stage of an MMS message delivery is to send an MMS notification message over WAP push. (See http://www.nowsms.com/howmmsworks.htm) In this case, the MMS notification would be posted to the PPG. NowSMS is still doing MMSC direct delivery. (And the recipient devices need to have network access to allow them to connect back to the NowSMS MMSC to retrieve messages after they receive the MMS notification.) The phone number format in NowSMS stays the same. But when we submit to the PPG, the phone number gets encapsulated similar to how you describe: WAPPUSH=PhoneNumber/TYPE=PLMN@domain But it is NowSMS that does this encapsulation. Unless Verizon's PPG performs some magic, you'd be better off trying to get a direct SMPP connection to them, and configure NowSMS to perform "WDP Adaptation", so that it can deliver the push via SMS over SMPP in a manner that is compatible with most CDMA systems. We have several mobile operator customers who use NowSMS as an MMSC on their CDMA networks. Rather than going the separate PPG route, we've found that WDP Adaptation over SMPP is a better solution. The issue is that you basically need to be directly connected to the operator's SMSC for WDP Adaptation support as SMS aggregators don't understand it. | |||

How does one define multiple PPG's and route them accordingly in this situation? Do I define multiple URLs under [WAPPPG]? If so, how do I distinguish? | |||
| Devashish Rughwani Unregistered guest |
Hi My question is a general one I want to know whether PPG is specific to GSM and CDMA networks.In other words Can I use the same PPG for GSM/CDMA n/ws ? Thanks | |||
| Bryce Norwood - NowSMS Support Board Administrator Username: Bryce Post Number: 3991 Registered: 10-2002 |
We do not currently have a way for a single server to route to multiple PPGs. This would indeed be useful in some environments, however this particular feature was designed for a situation where a mobile operator wants to install our MMSC and route all MMS notifications through their existing push proxy gateway. To be honest, this configuration option is rarely used by our customers. We added it to meet one particular customer requirement, but other CDMA operators have found our SMPP support for WDP Adaptation to be a better solution. If you need to connect to multiple PPGs, the only suggestion that I could come up with would involve multiple NowSMS servers, where if the message needs to go through a particular PPG, it gets routed to a particular NowSMS server that has that PPG connection defined. -bn | |||

The underlying WAP Push protocol has different message formats for CDMA SMS vs. GSM SMS. I'd need to know more about the specifics of your question to answer it properly. I'm assuming that you're looking at using NowSMS as a push proxy gateway (which is different from the other active discussion here where NowSMS is interfacing with a separate push proxy gateway). The same PPG could be used for both CDMA and GSM networks, as long as the SMSC connection supports WDP Adaptation for both CDMA and GSM. WDP Adaptation is a WAP profile for SMPP. It allows a WAP push to be specified in a way that is independent of the underlying SMS protocol ... and the SMSC needs to then adapt the message to the appropriate WAP format for the destination network. Or, you can have two SMSC connections defined, where the GSM connection uses native WAP Push format, and the CDMA connection uses WDP Adaptation. Unfortunately, if you're not a mobile operator, or closely associated with one, you're not likely to get far. It can be difficult to get an SMSC connection to a CDMA operator that supports WDP Adaptation unless you are directly connected to the operator SMSC (no intermediaries). -bn | |||

Hi, To support MMS in a CDMA environment, we require that the SMSC support "WDP Adaptation" for SMPP. This basically means that the SMSC understands the "WAP" service type and maps it to the appropriate CDMA teleservice, and that the source_port and dest_port parameters from the optional SMPP TLV parameters are supported. Define your SMPP connection in NowSMS, then under "Advanced Settings", check "Use WDP Adaptation for WAP Push and MMS Notifications (required for CDMA)". Next, try to send a simple WAP Push message from the NowSMS web interface, and see if it comes out properly on the mobile phone. If the WAP Push message goes through ok, then move forward to MMS. One consideration for the CDMA environment is that you want to keep the MMS notification size small, as the SMSC might not support segmentation. By default, with the "WDP Adaptation" setting, NowSMS will send the complete MMS notification to the SMSC in one submit request, which may be larger than 140 bytes. If you want NowSMS to segment the message (like it does in GSM environments), then v5.51b adds another advanced setting, titled "Use TLV parameters for port numbers and segmentation". Check that setting and the "WDP Adaptation" setting to have NowSMS perform message segmentation. Still, some SMSCs might not handle segmented messages properly. So you want to take some steps to reduce the size of the MMS notification message that gets sent over SMS. (The following thread talks about these issues: http://support.nowsms.com/discus/messages/1/641.html.) -bn | |||

Can you get a gsm modem to work on a cdma network? | |||
| Bryce Norwood - NowSMS Support Board Administrator Username: Bryce Post Number: 4672 Registered: 10-2002 |
No. And there is not a standard for CDMA modems for sending/receiving SMS. Every CDMA phone with a built-in modem capability that I have seen, only supports the modem interface for data/internet connectivity, not for SMS. (There was one manufacturer that we were working closely with a couple of years ago, which had defined modem command extensions for SMS sending in their phone/modem interface ... but that manufacturer abruptly exited the CDMA market before we implemented their spec. I have not seen any other phone manufacturers with such modem extensions, although I'd be happy to find out about any.) What I do know is that there are some dedicated external CDMA modem devices which implement a subset of the standard GSM modem interface. For example, Multitech's CDMA modems, which are based upon a Wavecom chipset. We support these modems, beginning in NowSMS v5.51b, where we can use them in "text mode" (as opposed to "PDU mode") for sending/receiving SMS text messages. If you're running a version of NowSMS prior to v5.51b, and when you test the modem in NowSMS, the error message says "Modem does not support SMS PDU Mode" ... then v5.51b would make a difference. Find it at the following link: http://support.nowsms.com/discus/messages/53/9502.html If you receive any other message, then v5.51b is not the answer, and the modem does not provide an SMS interface (or if it does, we don't have the specifications for it). -bn | |||

I'm not aware of any Nokia CDMA handsets which implement a modem interface for sending/receiving SMS. You might try checking the Nokia web site to see if there is a "PC Suite" software version that supports your handset. But other than that, I can offer no advice. NowSMS can only use CDMA modems that implement a subset of the ETSI GSM 07.05 command set for sending/receiving SMS messages that was originally published for GSM modems. I am not aware of any CDMA mobile phones that implement this interface, only some dedicated CDMA modem devices. -bn | |||

Hello, I heard there people developed application Samsung CDMA cellular phone with USB/Serial RS-232C cable to send/receive short message. I would like to do similiar application either on Linux or Windows. I googled to find Samsung programming manual/guide, but until no success. How can I to find detailed information on programming Samsung CDMA phone? Thanks, Balgaa | |||
| Bryce Norwood - NowSMS Support Board Administrator Username: Bryce Post Number: 5287 Registered: 10-2002 |
Hi Balgaa, If you find such a guide, I would love to hear about it. The only details that I have been able to find about "AT command" interfaces on Samsung CDMA devices, do not include any commands that pertain to SMS support. I think the application you are thinking of is "BitPim". And to the best of my knowledge, it cannot be used to send SMS from a CDMA phone. They have found how to read SMS messages from a number of LG CDMA phones when connected with a USB/serial cable, and they can write SMS messages to the phone ... but I don't think they can make the phone send the messages. There are also a couple of Samsung models that I think they can read SMS messages from. Unfortunately, CDMA has not standardised AT command interfaces in this area, where GSM has. -bn | |||

Hi Bruce, As I know one of my Korean partner doing two-way international Korea<->HK. They installed one node with GSM phone in HK to send/receive message from local customer send it over Internet to other node with Samsung CDMA phone installed in Korea. They developed custome software for it. They told me they are using Samsung IS-95B CDMA phone connected to PC through RS-232C/USB cable. Balgaa | |||

Hi all, I was so happy to find out the NowSMS supports CDMA MMS messaging. The only downside here is the PPG notification which as far as I understood from previous posts requires a direct connection to the operators PPG. Well, I'm not sure I can get that connection, but as I am looking for simulating an entire MMS cycle (as I do today in the GSM world), I was wondering if I could run this scenario: 1. Configure the CDMA handset's MMS IP to the NowSMS server, and send an MMS message 2. Have the NowSMS connect to a GSM modem (GSM handset connected via cable to computer). 3. The GSM phone will send a PPG notification towards the CDMA phone (which will be interconnected to the CDMA operator). 4. CDMA recipient handset receives PPG notification and connects to NowSMS to retrieve message. Would that work? Cheers | |||

Hi, First to address Balgaa's most recent posting. The conversation has jumped from SMS to MMS here, and the issues are a little different. Sending MMS via a CDMA modem is not as difficult as sending SMS via a CDMA modem. The GSM modem interface for sending SMS uses extended AT commands. There is a standard defined in GSM for this, ETSI GSM 07.05, which has been superceded by 3GPP TS 27.005. There is not a similar standard defined in CDMA or 3GPP2. (3GPP2 manages the CDMA2000 specification, which is the 3G evolution of CDMA. 3GPP manages the WCDMA/UMTS specification, which is the evolution of GSM/GPRS.) There are a few CDMA modems (Multitech makes one) which implement the GSM modem interface in a CDMA environment. However, they only support text messages. WAP Push and MMS messaging require the ability to send binary SMS messages. Refer to http://www.nowsms.com/howmmsworks.htm for more background on how MMS works. So even with a CDMA modem that supports these AT commands, you are limited to only being able to send text SMS messages. If you want to send MMS messages via a CDMA modem, the only option is to send them via the operator MMSC. (Refer back to http://www.nowsms.com/howmmsworks.htm) And you can actually do this with NowSMS, but the configuration is a bit more difficult than with a GSM/GPRS modem. See my explanation of how this is done in the following thread: http://support.nowsms.com/discus/messages/485/8412.html Note that without the ability to receive binary SMS messages, this CDMA modem interface for MMS could only be used to send MMS messages, not to receive them. -bn | |||

And now to address the other posting ...
The quick answer. No, that is not going to work. 1. Ok. 2. Ok. 3. No. You talk to a PPG (Push Proxy Gateway) over TCP/IP, not via a GSM modem. You can send a WAP Push via a GSM modem, but when you do, this is a WAP Push that is in a GSM specific format. Generally speaking, the messaging gateways that connect carrier GSM and CDMA networks together do not perform the necessary format conversion. 4. If you managed to get the proper format notification through to the CDMA device, then this would work. But you will not get there via this connectivity route. All of this is not a technical limitation of NowSMS. But rather it is just the real world situation that CDMA networks are not as accessible as GSM networks. What are the options? 1.) Deliver MMS messages through an operator MMSC: a.) You could deliver MMS messages via the CDMA operator's MMSC, connecting to the MMSC with a protocol such as MM7 or MM4 (TCP/IP based protocols). b.) You could deliver MMS messages via the CDMA operator's MMSC, connecting with a CDMA modem. (As referenced in posting above this, also see http://support.nowsms.com/discus/messages/485/8412.html.) c.) You could connect to a GSM mobile operator's MMSC (via MM7/MM4 or GSM modem) and use their interconnect for exchanging messages with the CDMA operator. 2.) NowSMS as the MMSC: a.) Use an SMPP connection to the CDMA operator, where the SMSC supports "WDP Adaptation". NowSMS can format the MMS notifications so that the CDMA operator's MMSC can deliver them in the correct format over the CDMA network. (We have several CDMA based mobile operators that use NowSMS as their MMSC, and this is the technique they use.) b.) Configure NowSMS to route MMS notifications via a WAP Push Proxy Gateway (PPG) at the CDMA mobile operator. (This is a global option in NowSMS, so a single NowSMS system configured with this option could only route WAP Push and MMS notifications to a single PPG.) c.) Upcoming in the NowSMS 2006 release, we are also adding some additional HTTP support for CDMA SMS, intended primarily to support customers in test environments that are using Agilent 8960 test kit in CDMA and CDMA2000 environments. (The problem is that MMS notifications are binary SMS, and typically are too large to be sent in a single SMS message, requiring multiple segmented messages. Sending a segmented WAP Push/MMS Notification message in the CDMA environment requires that the MESSAGE_ID value be set to the same value for each segment of the message. Typical SMSC interfaces do not allow the application to set the MESSAGE_ID value ... hence the problem.) -bn | |||

Thanks Bryce for your detailed answer. If I am to put your answer in a one liner then there are basically one way I can get the NowSMS to send PPG notifications in a CDMA environment, and that is to have a direct connection to the operator's PPG (all others - MM7, MM4 etc, will also require direct connection to the Operator, and will be retrieved from the Operator's MMSC - which is not what I am looking for). So... That brings me to my next question: Are they any operators who offer "PPG services"? (or other companies of that matter?). I'd really appreciate a contact person or something similar in the US. Thanks, Noam | |||
| Bryce Norwood - NowSMS Support Board Administrator Username: Bryce Post Number: 5347 Registered: 10-2002 |
Hi Noam, Getting access to an operator's PPG is usually more difficult than getting an appropriate SMSC or MM7 connection. The reason is that many operators don't bother with having an official PPG ... or if they do, they only have it setup for internal use, and don't provision external accounts. We originally added the support for NowSMS to route MMS notifications via a PPG at the request of a mobile operator who was working closely with a PPG vendor. They wanted all pushes to go through the PPG. When they went live with their MMSC, they decided they were better off bypassing the PPG. We then started promoting the PPG route as a way for CDMA mobile operators to use NowSMS as their MMSC. However, this inevitably led to prospective customers asking us to recommend a PPG for CDMA. (NowSMS can be a PPG for GSM.) We then added support for "WDP Adaptation" over SMPP. And within the CDMA operators themselves, SMSCs that support "WDP Adaptation" over SMPP seems to be quite common, as this is normally how a PPG would need to interface with an SMSC in a CDMA environment. The problem is that when you go through an SMSC aggregator, the aggregator doesn't understand about WDP adaptation. So you generally need to have an account directly with the operator SMSC, with binary messaging enabled. All said, it seems to be very difficult to get this type of connection unless you are a part of the mobile operator. But easier to get than a PPG connection... That said, you're talking about the US. And one of the problems in dealing with the US CDMA operators is that they are extremely big companies... I know in the past that Sprint did offer PPG connections through their developer program. But I am not sure that they still do. Probably the best way to get more information for both Sprint and Verizon would be through their developer programs: http://developer.sprint.com/ http://www.vzwdevelopers.com/ -bn | |||

| Bryce Norwood - NowSMS Support Board Administrator Username: Bryce Post Number: 5724 Registered: 10-2002 |
Hi Balgaa, Download the trial version of NowSMS, and try it. Let me know what errors you might receive. Unfortunately, it is likely that you will only be able to use the modem for sending/receiving SMS text messages, because the documentation that I have seen for Wavecom chipsets in the CDMA environment is that they do not support binary messages in that environment. -bn | |||

Henry, I have never encountered a CDMA mobile phone that exposed a modem interface for sending SMS messages. This is not to say that one does not exist, but I am not aware of any. Therefore, I would not expect NowSMS to work with your CDMA mobile phone. There are dedicated CDMA modem devices (like the one from Multitech) that could be used in a CDMA environment. But I am not aware of any mobile phones that support this type of modem interface. -bn | |||

Hi there Could you please advise whether anyone has successfully got NowSMS working with the Anydata iPort CDMA modem? Kind Regards Mike | |||
| Bryce Norwood - NowSMS Support Board Administrator Username: Bryce Post Number: 6022 Registered: 10-2002 |
Hi Mike, I haven't tried it. But based upon the developer documentation on the manufacturer web site (which is about 5 years old), I do not expect NowSMS to work with the modem. I've made an inquiry with the manufacturer for more information, so we will see if that leads anywhere. Based upon what I see on their web site, they seem to have a proprietary implementation for sending/receiving SMS. Unfortunately, the 5 year old documentation on the web site only contains limited information about receiving SMS with the modem, and no information on sending SMS. -bn | |||
