Method for receiving SMSCB messages during GPRS/EDGE data transfer mode
First Claim
1. A method for receiving GSM short message service cell broadcast data, comprising the steps of:
- receiving a new message block;
determining whether the new message block is a recognized type of cell broadcast service message;
determining whether the new message block is geographically coherent with existing partially received data;
determining whether the new message block is temporally coherent with previously received message blocks;
inserting the new message block within a received message structure;
determining whether the received message structure is complete and correctly received; and
assembling the complete message from received message blocks and sending the complete message to an upper software layer.

Abstract
An unacknowledged, reliable short message service cell broadcast message reception protocol method to enable short message service cell broadcast messages to be constructed from the fragments of the multiple repetitions of the cell broadcast service messages which are repeated on the cell broadcast channel. When a new message block, corresponding to a recognized type of cell broadcast service message, is geographically coherent with existing partially received data or contains message components previously received, and is temporally coherent with previously received message blocks, the new message block is inserted within a received message structure. If the received message structure is complete and correctly received, the complete message is assembled and sent to an upper software layer.

11. A data and signaling stack of a wireless communication network, comprising:
-
a reception manager receiving cell broadcast channel data and outputting only completely received short message service cell broadcast messages, wherein, in response to receiving the cell broadcast channel data, the reception manager inserts the cell broadcast channel data within a received message structure when the cell broadcast channel data is a recognized type of short message service cell broadcast message and is geographically and temporally coherent, determines whether the received message structure is complete and correctly received, and if complete, assembles the complete message from received message blocks and sends the complete message to an upper software layer; and
a physical layer interface receiving messages and sending short message service cell broadcast messages to the reception manager, wherein the completely received short message service cell broadcast messages output by the reception manager are construed from fragments of multiple repetitions of short message service cell broadcast messages. - View Dependent Claims (12)
