Hi Bryce I'm interested in SMS etc. and I’ve read a lot of your articles and quite useful. Please answer me a question about sms notifications for mms/java application downloads. 1. Are there any different between the normal sms and sms notification? e.g. sms is from normal GSM gateway and service notification is over GPRS? 2. How does mobile know which sms is normal text message and some sms messages are notification? 3. For the sms notification, does mobile and gets URL, login id & pwd from the sms content to retrieval the specified content? Rgds & thnx thanks | |||

Hi Johnson,
Both occur over GSM/SMS. A WAP Push message (service indication) is transmitted as a binary SMS message. When you select to load the link that is referenced in the push, that is when GPRS (or a dial-up WAP connection) would be activated.
For starters, the message is in binary format instead of text format. Within the binary SMS message format, there are different attributes that can indicate that a message is of a particular content type. For many types of binary SMS content, a user data header (UDH)is included in the SMS message, and the UDH is used to identify the type of message content. WAP Push messages over SMS are formatted similar to Nokia Smart Messaging format messages. The UDH specifies a destination port number for the message to be routed to a particular application in the phone. In this case, there is a port number for WAP push, and the phone identifies the message as a WAP push message, and it then decodes the message as such.
A WAP push service indication message includes a text component and a URL. There is no login id and password. See the following thread for some comments from Bryce on this topic: http://support.nowsms.com/discus/messages/132/2197.html (Bryce has been a bit overwhelmed by the amount of traffic on this forum, so he and I are going to concentrate on moderating different forums within the board.) -- Kent Williams Now Wireless Support http://www.nowwireless.com | |||

Big thanks Kent Williams! From your forum, I successfully obtain enough information on wap push concept and hex encoded method for SI etc, and now I can send sms push messages to nokia mobile, the mobile also can download color picture, melody thru wml etc..  However, get small problem for java game download: .jad file displays properly, accept to retrieve .jar file from server, it takes quite a long time and mobile says: invalid file and stop GPRS. Really don’t know what happening? Due to telco blocks .jar files or downloading url port settings problem? BTW: what are mobile brands to support smart message? It highly appreciate your forum to cover most of mobile information thanks and regards | |||

I would like to know basic system configuration regarding sending MMS notification. As I understand SMS is used for UE to indicate that a MMS is awaiting retrieval in the MMSC, system configuration is following. MMSC-> PPG-> MMSC-> UE Is this correct? | |||

Johnson, Do you ever see a request come in to your web server to retrieve the JAR? Some Siemens phones expect to use HTTP to download a JAR. This can cause a problem because the phone needs to be configured to connect to a GPRS APN that supports full internet access in order to be able to retrieve the JAR. Some Motorola phones issue some strange requests that not all WAP gateways understand. (And in these cases I have seen this type of error.) It is also possible that the operator gateway does not support segmentation-and-reassembly (SAR) in their WAP gateway, and therefore has some size limitations. It may be worth experimenting with some different sizes to determine if that is the problem. Unfortunately, if that is the problem, the only way around it is to use an alternate gateway.
Smart message is a Nokia specification, so that is primarily supported by Nokia phones. WAP Push uses a format similar to Nokia Smart Messaging, but it is widely supported by most WAP phones released over the past couple of years. -bn | |||

Yes. Although the MMSC may generate the push directly without going through an actual Push Proxy Gateway. For example, that is what our Now SMS/MMS Gateway does. (Although it does also have an option for routing the push notifications through a push proxy gateway ... but we primarily use that only for sending the push in non-GSM environments, such as CDMA.) -bn | |||

Bryce, I read about your company's SMS/MMS gateway reply on 28 Jan 2004. I am a applications developer in China. Currently, I am trying to develop WAP applications that can display properly over my CDMA phone over China Unicom's CDMA network. However, when I want to get a URL that I can simply click on to access a WAP site on my CDMA phone over a CDMA netwk, the URL is a text message.On a GPRS network however, when I test by subscribing to the same service, I obtain a binary WAP push message ie I can simply click on the link and access the WAP site. I'll like to seek your opinion on where the problem lies: - issit the PPG? Can the PPG only be controlled by the country's telecom operators? - issit the phone ie it cannot interpret the binaries properly? Thanks alot! | |||

hi Hazel, If u wanna develop push applications for China Unicom(CU),u'd better use their PPG service to send the push msgs. Since the CU selected Openwave's Wap gateway(plus PPG) to provide wap services nationwide for WAP1.x terminals, the NON-STANDARD push protocols developed by Openwave proprietarily became the de-facto standards. So there is no hope for u ,an application developer, to generate the push sms and send it directly to the terminal.EVEN u know the detailed format of Openwave's proprietary protocols wont help. So for ur questions, 1) You should contact CU for the access rights to their PPG server; 2) Most of the CDMA terminals used in China can only accept push format from Openwave. | |||

Hello freewill, Thanks for your reply. Do you mean that even if we have the binary format of the service indication message (the term used by nokia phones for the binary used over GSM/GPRS netwk), it is not possible for us to send a message to the user in a way that is convenient to him? ie he just needs to click on the link? thks | |||

hi hazel, I think for GSM network, the standard push format works. U can try it. | |||

hi, what about the CDMA network? Why can't the WAP push format work? | |||
| freewill Unregistered guest |
hi hazel, As I said before, Unicom uses openwave's push msg for it's cdma network. there's some tricky parts in their format. | |||
| hazel Unregistered guest |
Hello freewill, thanks for your very prompt responses from what i have gathered from your replies so far, does it mean that, in order to develop WAP applications that can work over Unicom's CDMA network, I will need to use Openwave's API? thanks. | |||

freewill, do u mean that all China Unicom's PPG can only recognize openwave's non-standard WAP Push? but I've heard that Openwave's PPG can also accept standard SI wap push now. The problem I've met is how to send out that binary message. To avoid bothering the link ID that CU requires to send a message on the internet,I have to turn to a CDMA Modem.However,CDMA modem doesn't support PDU mode.Then How can I send the binary message in a text mode? thanks for any advice. Jinxiang,Chen | |||

hi, what WAP standard is used to convert url into binary for sending? | |||
| freewill Unregistered guest |
These days we're busy testing our wap 2.0 gateway(ppg) with CU, fortunately my tasks were rather successful, so I'll leave BJ for SH tomorrow. Maybe I'll visit this site less and less, pls dont hesitate to write me an email to ask me questions on WAP related issues. to hazel, 1)Yes , I think to use openwave's push library is a wise and time-saving choice for u. 2)The related standards may include but is not limitted to WAPWSP/WAPWDP/WAPServiceIndication/SMPP/IS 637 SMS to chenjinxiang, 1)As far as I know, except for the online-push which is only supportted by Toshiba 618 phone, the current runing PPGs in China Unicom cant support standard SI. 2)I'm not familiar with CDMA modem, usually PPG send such kind of msgs via SMSC or SMG. | |||

hi hazel, I've got ur mail,but cant find the attachment u mentioned. An even worse thing is my hotmail failed in sending my reply. | |||

Hi freewill, Does the current PPG used in China support SAR (segmentation and reassembly)? What would be the technical differences (in terms of implementation for the developer) between WAP 1.2 and WAP 2.0? Thanks! | |||
| freewill Unregistered guest |
to support SAR, both WAP gateway and Terminals should implement SAR protocol. For WAP gateway ,SAR support is a must;As I'm not that familiar with terminals I'm not sure whether it is an optional for cell phones. The fact is that most cdma wap1.x enabled phones can support SAR though the max. size of file can be downloaded varies. For Wap application developer,it's much more easier to program under wap 2.0,since wap 2.0 supports XHTML and TCP ... | |||

hi, has anybody used an SMSC to send a service indication message via WAP in china? thks | |||
| RyanHarrison Unregistered guest |
Hi. Help needed. I download java games to my Nokia 3200. Then once sent, I open it only to receive a message, file format not supported. The original file was under the .jar format and it did not work. Then somone told me I needed a Jadmaker program to change the file to .jad. I did so and now the files are .jad. Instead of being 60-100kb, etc., when I send them over to my phone via Infared, they are now very low in size (0.4-6kb). The file format is still though not recognized. What's the problem and what do I need to play java games? Thanks. | |||

Hi everyone. I would just like to know if we are able to retrieve our previous SMS (text) messages, say couple of days back. My phone, whice obviously doesnt hold that much Kbits of data keeps on asking me to delete messages before I could receive more. | |||

From where can i decode the information regarding the MMS notification indication that i recieve on my mobile handset. I mean, how can i get to know the encoding technique used ( ex: UCS2, UTF18, etc) for encoding the MMS notification, which is sent by the MMSC? | |||
