GSM cell broadcast SMS message transmission in CDMA communication systems
First Claim
1. A method for receiving Cell Broadcast Short Message Service (CBS) messages in a CDMA communication system, comprising:
- receiving a CDMA message having encapsulated therein a broadcast SMS message;
processing a designated field or subfield of the CDMA message to determine whether the broadcast SMS message is a GSM CBS message or a CDMA broadcast SMS message; and
recovering the GSM CBS message from the CDMA message if the GSM CBS message is encapsulated in the CDMA message.

Abstract
Techniques to send GSM CBS messages over a CDMA air interface. The encapsulation of a GSM CBS message in CDMA messages may be achieved using various schemes. An indication is provided at each of a number of pertinent layers to allow the terminals to determine whether a GSM CBS message or a CDMA broadcast SMS message was sent. These indications include (1) a value in a designated field or subfield of a Data Burst Message, (2) a new value for a Category field in a Service Category parameter of an SMS Broadcast Message, and (3) a new value for a Msg_Encoding field in a User Data subparameter of the SMS Deliver Message.
