CDMA IS-637 SMS Adapter

This appendix describes an adapter that uses the messaging API with the CDMA IS-637 SMS service.

C.1.0 CDMA IS-637 SMS Message Structure

CDMA SMS messages are defined in the CDMA IS-637 standard [6].

C.2.0 Addressing

The same sms: URL connection string is used as for GSM SMS (See Appendix A).

C.3.0 Port Numbers

The IS-637 SMS protocol does not include a port number or any other field for differentiating between recipient applications. For this purpose, the WAP WDP for IS-637 SMS defined in section 6.5 of the WAP Forum WDP specification[5] MUST be used.

Similarly, any rules for segmentation and reassembly follow the WAP WDP guidelines for adapting CDMA SMS messages for a common behavior with corresponding GSM SMS bearer capabilities.

Messages without a port number are sent as normal SMS messages targeted for presentation to the end user.

CDMA SMS messages MUST support a minimum of 3 concatenated messages to be consistent with the GSM SMS message adapter.
