摘要:
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.

摘要:
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.

摘要:
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.

The disclosure provides a method for updating an air interface key, a core network node and user equipment. The update method comprises: a core network node receives a relocation indication message, wherein the relocation indication message is configured to indicate that the User Equipment (UE) is about to relocate to a target Radio Network Controller (RNC) from a source RNC (Step S602); the core network node uses the key parameter to calculate a next hop enhanced key (Step S604); and then the core network node sends the next hop enhanced key to the target RNC (Step S606). Through the disclosure, the forward security of the user is guaranteed, and thus the communication security of the radio access system is improved.

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 (500); and when the target RNC receives a message from the user equipment and learns that the user equipment supports the enhanced security capability, the target RNC notifies a core network to establish and enable the enhanced air interface keys on the network side and in the user equipment respectively (501). With the method of the disclosure, during the Serving Radio Network Controller (SRNC) relocation of the user equipment in a wireless communication system, when the air interface keys are enabled and the legacy or enhanced user equipment moves between a legacy network and an enhanced network, timely enabling of security keys is achieved with respect to different security capabilities, ensuring normal accomplishment of the relocation process, and therefore ensuring normal proceeding of subsequent communication.

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.
