Synchronization of stored service parameters in a communication system
First Claim
1. A method of synchronizing stored service parameters comprising:
- transmitting a partial configuration from a base station to a mobile station;
calculating a CRC of the partial configuration in the base station;
combining the CRC of the partial configuration with a stored CRC in the base station to update the stored CRC in the base station;
calculating the CRC of the partial configuration in the mobile station;
combining the CRC of the partial configuration with a stored CRC in the mobile station to update the stored CRC in the mobile station;
transmitting the stored CRC in the mobile station to the base station;
comparing the transmitted stored CRC with the stored CRC in the base station; and
using the configuration comprised of one or more partial configurations for communication between the base station and mobile station when the compared stored CRCs match.

Abstract
Techniques for synchronization of stored service parameters are disclosed. In one aspect, a configuration identifier is transmitted from a mobile station to a base station, and compared with an identifier generated in the base station. If the identifiers match, the configuration is used for communication. In another aspect, the identifier is generated by selecting an identifier associated with a configuration from a configuration table. In yet another aspect, the identifier is generated by computing a cyclic redundancy check (CRC) of the configuration. Various other aspects are also presented. These aspects have the benefit of preventing attempted use of unsynchronized stored service parameters and associated call setup failures and subsequent renegotiation, with the net effect of reducing call setup time and more efficient use of system resources.
