    Abstract: PROBLEM TO BE SOLVED: To provide a method, apparatus and system provide for efficient use of communication resources for providing broadcast services in a communication system. SOLUTION: A receiver receives a first broadcast controller identification from a first base station 101, and a second broadcast controller identification from a second base station 160. A controller coupled to the receiver determines whether the first and second broadcast controller identifications are associated with use of a common set of broadcast parameters. A transmitter transmits a request for transmission of a new set of broadcast parameters when the first and second broadcast controller identifications are not associated with use of the common set of broadcast parameters. After receiving the new set of broadcast parameters, the receiver uses the new set of broadcast parameters for receiving broadcast services. COPYRIGHT: (C)2010,JPO&INPIT

    Abstract: PROBLEM TO BE SOLVED: To provide a system and a method for reliably broadcasting content to a plurality of users and facilitating distribution of parts of the broadcast content that either were not received by particular users, or were received with errors. SOLUTION: The wireless communication system is configured to broadcast content from a content source to a plurality of user devices. The content source is configured to provide the content to a base station. The base station parses the content into a plurality of segments and associates sequential identifiers with each of the segments. The content is then broadcast to each of the user devices. An identifier of an alternative data source is also provided to the user devices. When a mobile station receives the segments, it examines the segment identifiers to identify missing segments. The segments are then retrieved from the alternative data source identified by the base station. COPYRIGHT: (C)2011,JPO&INPIT

    Abstract: PROBLEM TO BE SOLVED: To provide a method and apparatus providing message integrity regardless of the operating version of an authentication center or an interface between the authentication center and a mobile switching center, in a communication system.
    SOLUTION: The method includes 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 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: PROBLEM TO BE SOLVED: To provide an apparatus and a method that can be used by a person for securely authenticating his identity by issuing a secure identifier.SOLUTION: An authentication apparatus 200 has a processor 208, at least one activator 204 coupled to the processor 208, an internal clock 212, a random number generator 216, an optional additional static memory 220 and a signal output 224, and generates a digital signature using a current time (time identifier), an identified secrete key, and a generated random number, which are called secure identifiers, and issues it. A receiver receives the issued secure identifiers to verify that the secure identifiers have been appropriately sent. The secret key corresponding to a transmitted key identifier is accessed, the validity of the secure identifier is determined using the accessed key, and that the time indicated in the received secure identifier is verified to be within acceptable time tolerances.
