    Abstract: Methods and mobile stations for transmitting, receiving and processing peer-to-peer communication signals without a base station or network element. A transmitting mobile station may alternate two or more long code masks to generate one or more pseudorandom noise (PN) codes to spread data for transmission. A receiving mobile station receives the spread data and achieves synchronization with the transmitting mobile station.

    Abstract: A priority access channel assignment system and a messaging protocol for wireless mobile stations. A mobile station (MS1, ..., MS10) originates a call that manually or automatically includes a request for priority access. If system resources are unavailable to process the call immediately, the origination message is processed by a base station (BS1, BS2) and a mobile switching center (MSC) using a plurality of messaging protocols to determine the time at which the call was originated and the priority associated with the call. Based on priority and arrival time, the base station (BS1, BS2) queues the call where higher priority calls are placed in a higher position in the queue than lower priority calls. Calls having identical priority may be placed in the queue in order of the time of arrival. When system resources become available, the pending call with the highest priority is assigned a channel and the call is processed in a conventional manner.

    Abstract: In a communication system (100), a method and apparatus provides for message integrity regardless of the operating version of an authentication center (198) or an interface (197) between the authentication center (198) and a mobile switching center (199). The method and apparatus include generating a cellular message encryption algorithm (CMEA) key, and generating a CMEA-key-derived integrity key (CIK) based on the CMEA key for message integrity between a mobile station and a base station. The mobile station transmits a registration message to the base station, and determines an operating version of the authentication center (198) in communication with the base station based on whether the mobile station receives a registration accepted order or some elements of an authentication vector from the base station. The CIK is generated based on the CMEA key, if the mobile station receives a valid registration accepted order from the base station.

    Abstract: Apparatus and method for provisioning an access key used for a controlled access broadcast service is disclosed. In one aspect, a method for secure processing in a device that securely stores a secret key comprises receiving a plurality of challenges from a network, generating a plurality of ciphering keys based on the secret key and the plurality of challenges, and generating an access key based on the plurality of ciphering keys.
