Process and Receiver for Recovering Paging Message
First Claim
1. A method of processing a paging message, the method being suitable for a User Equipment for a wireless telecommunication system, and comprising the steps of:
- monitoring a Paging Indicator included in a Paging Indicator Channel message;
upon reception of a Paging Indicator relevant to said User Equipment, detecting and decoding a paging channel in order to decode a corresponding paging message;
computing and checking the CRC of said paging message and, in case of failure of the CRC check, performing the following steps;
performing a partial checking of said paging message, said partial checking being limited to a number of fields of said paging message;
determining whether said paging message is relevant to one single UE;
if said paging message is relevant to one single UE, replacing the bits not relevant to said single UE by default bits and computing and checking a new CRC; and
if the new CRC check succeeds, forwarding the processed paging message to the Radio Resources Control layer.

Abstract
A method of processing a paging message, the method being suitable for a User Equipment (UE) for a wireless telecommunication system, and comprising the steps of:—monitoring a Paging Indicator (PI) included in a Paging Indicator Channel (PICH) message;—upon reception (210) of a Paging Indicator (PI) relevant to said User Equipment, detecting and decoding a paging (PCH) channel in order to decode a corresponding paging message (220);—computing and checking the CRC (230) of said paging message and, in case of failure of the CRC check, performing the following steps:—performing (240, 250) a partial checking of said paging message, said partial checking being limited to a number of fields of said paging message;—determining whether said paging message is relevant to one single UE (260);—if said paging message is relevant to one single UE, replacing (261) the bits not relevant to said single UE by default bits and computing and checking (262) a new CRC—if the new CRC check succeeds, forwarding the processed paging message to the Radio Resources Control (RRC) layer.

9. Receiver suitable for a User Equipment for a wireless telecommunication system, adapted to process a paging message, said receiver comprising:
-
a monitor adapted to monitor a Paging Indicator included in a Paging Indicator Channel message; a detector and a decoder, respectively adapted to detect and decode the PCH channel in order to decode a corresponding paging message upon reception of a Paging Indicator relevant to said User Equipment; a processor adapted to compute and check the CRC of said paging message, Characterized in that it further includes a processor adapted to perform a partial checking of said paging message in case of failure of the CRC check, said partial checking being limited to a number of fields of said paging message; a determination unit adapted to determine whether said paging message is relevant to one single UE; a processor adapted to replace the bits not relevant to said single UE by default bits and compute and check new CRC, if said paging message is relevant to one single UE; and means for forwarding the processed paging message to the Radio Resources Control layer if the CRC check succeeds. - View Dependent Claims (10, 11, 12, 13, 14)
