20090207773 | MBS SYSTEM, MBS ZONE PARTITIONING METHOD, AND METHOD FOR IMPLEMENTING MBS IN A WIRELESS NETWORK - An MBS system, an MBS zone partitioning method, and a method for implementing MBS in a wireless network are disclosed. In the present invention, each MBS zone is managed by an MBS proxy function entity as a signaling plane entity, and the MBS proxy function entity allocates, manages and maintains the resource within the MBS zone. An ASN gateway containing an MBS DPF is adapted to establish, modify, or delete an MBS bear between the MBS DPF and a base station. An MBS agent contained in the base station is adapted to establish the MBS bearer and classifies and distributes MBS packets cooperating with the MBS proxy function entity and the MBS DPF. | 08-20-2009 |
20090213779 | MULTI-HOP WIRELESS RELAY COMMUNICATION SYSTEM AND DOWNLINK DATA TRANSMITTING METHOD AND DEVICE - A downlink data transmitting method is applied to a multi-hop wireless relay communication system. The method includes the following steps. A network unit obtains an identifier of a next hop network unit corresponding to a connection identifier (CID) in a downlink medium access control protocol data unit (MPDU) header according to an existing corresponding relationship of the CID and a path ID, and sends the downlink MPDU to the next hop network unit by utilizing the obtained identifier of the next hop network unit, so that a data transmission of multi-hop wireless communication system is realized without changing a current user terminal and protocol structure of a core network. Meanwhile, a multi-hop wireless relay system, and a base station and relay stations applied to the system are described. | 08-27-2009 |
20090219850 | METHOD FOR TERMINAL TO JOIN MULTICAST BROADCAST SERVICE IN WIRELESS NETWORK AND SYSTEM USING THEREOF - A method for a terminal to join a multicast broadcast service (MBS) in a wireless network and a wireless communication system are provided, so as to enable a terminal to successfully join an MBS and receive MBS content. The method and the system relate to a wireless communication field. A terminal obtains MBS parameters that include a first ID indicating an air interface connection and a second ID indicating MBS content from a network, so that the terminal can receive the MBS content indicated by the second ID from the air interface connection indicated by the first ID after receiving the MBS parameters and thus successfully join the MBS. The terminal may initiate an MBS join process by sending an MBS join request message, so as to obtain the MBS parameters and join the required MBS. The network may actively initiate the MBS join process to send the MBS parameters to the terminal and invite the terminal to join the MBS. | 09-03-2009 |
20090238107 | METHOD FOR BEARER CONTROL AND DELETION, DATA DISTRIBUTION, AND MODIFICATION - A method for bearer control, bearer deletion, data distribution, and multicast broadcast service MBS modification are described, which enables MBS data to be received successfully and MBS sessions to be managed effectively. According to the invention involved in a communication field, service distribution information for one MBS service is maintained within MBS upstream and downstream nodes, and the MBS service distribution information is composed of a list of downstream nodes corresponding to the respective nodes. A corresponding service bearer and data distribution relation of the MBS are established and maintained based on the service distribution information, and service data of the MBS is distributed based on the service bearer and the data distribution relation. The MBS distribution information is pre-configured and/or dynamically maintained, the establishment of the service bearer is pre-configured and/or dynamically maintained, and the data distribution relation is pre-configured, distributed by default, and/or dynamically maintained. | 09-24-2009 |
20120294444 | Method and system for establishing enhanced air interface key - The disclosure provides a method and a system for establishing an enhanced air interface key. During a serving Radio Network Controller (RNC) relocation process, a target RNC with an enhanced security capability enables a received legacy key to perform security protection on communication in the serving RNC relocation process when the target RNC cannot learn from a relocation request sent by a source RNC whether or not a user equipment supports the enhanced security capability ( | 11-22-2012 |
20130014231 | Anchor authenticator relocation method and system - The disclosure provides an anchor authenticator relocation method and system. The method includes: after an old authenticator accepts an anchor authenticator relocation request of a Mobile Station (MS), a new authenticator sends an authenticator relocation request to an AAA server; when the AAA server's verification on the new authenticator is passed and the old authenticator confirms that the new authenticator is trusted, the anchor authenticator is relocated to the new authenticator. The disclosure provides a detailed solution to perform anchor authenticator relocation without re-authentication. | 01-10-2013 |
20130028421 | Method and System for Establishing Enhanced Key when Terminal Moves to Enhanced Universal Terrestrial Radio Access Network (UTRAN) - The present invention discloses a method and system for establishing an enhanced key when a terminal moves from an EUTRAN to an enhanced UTRAN, so as to ensure that the terminal can carry out normal communication safely in the enhanced UTRAN. The method includes: when the terminal moves from the EUTRAN to the enhanced UTRAN, a target enhanced serving GPRS support node (SGSN+) in the enhanced UTRAN deducing an intermediate key used in the UTRAN according to a mapped traditional key obtained from a source mobile management entity; and the terminal, after deducing the mapped traditional key, further deduces the intermediate key used in the enhanced UTRAN by using an algorithm which is the same as that of the target SGSN+ according to the mapped traditional key. | 01-31-2013 |
