Estimating the term…
A communication system controls access of a mobile station (MS) to a wireless communication network by generating a RAND Token and conveying the RAND Token and associated constraints to the MS prior to a determination by the MS of a need to access the communication network, wherein the RAND Token is used to authenticate the MS and need not be confirmed prior to the access attempt. By providing the MS with a RAND Token that need not be confirmed, as opposed to the prior art where an MS cannot know whether a global random challenge value provided to the MS prior to a determination by the MS of a need to access the communication network is stale and therefore must confirm the global random challenge value before using it, a call may be set up in an expedited fashion.
A method for controlling access of a mobile station to a wireless communication network comprising:
A method for accessing a wireless communication network comprising:
A base station comprising a processor that is configured to generate a RAND Token for a mobile station and convey the RAND Token and associated constraints on the use of the RAND Token to the mobile station prior to a next system access by the mobile station, wherein the RAND Token is used to authenticate the mobile station.
A mobile station comprising:
