摘要： Embodiments of the present invention relate to the technical field of wireless communications, and in particular to an access control method and device, for use in resolving the problem in the prior art that a user equipment cannot securely access an access points group (APG). According to the embodiments of the present invention, when a user equipment needs to access a network, the user equipment conducts network-layer two-way authentication with a local service center; after the network-layer two-way authentication succeeds, the user equipment conducts access-layer two-way authentication with a corresponding APG so as to enable the user equipment to access the corresponding APG after the access-layer two-way authentication succeeds. The embodiments of the present invention use dual-layer two-way authentication, and enables the user equipment to access a corresponding APG after the dual-layer two-way authentication succeeds, so that the user equipment can securely access the corresponding APG.

摘要： Embodiments of the present invention relate to the technical field of wireless communications, especially a method and device for joining an access node group (APG), for use in resolving the problem in the prior art of an access node being unable to join an APG securely. In the embodiments of the present invention, the access node performs network layer two-way authentication with a local service center after determining to join the APG; and the access node performs network configuration according to configuration information in a network configuration message after receiving the network configuration message sent by the local service center. Therefore, an APG corresponding to a user equipment follows the user equipment, and at the same time, it can be ensured that an access node may join the APG securely.

摘要： Disclosed are a method and device for controlling set-up of a user side bearer, aiming to solve the problem of an unnecessary signaling overhead caused by the fact that a UE initiates a TAU process after an SGW deletes cached downlink data of the UE when a timer has timed out, and an MME still initiates a set-up process of a user side between the UE and a base station. The method comprises: in a tracking area updating (TAU) process, a mobility management entity (MME) determining that a serving gateway (SGW) needs to send cached downlink data to a terminal UE; and the MME initiating a set-up process of an air interface user side bearer of the UE.

摘要： A method and network device for confirming ISR activation, optimize the way of activating ISR to solve the defects of prior art that the characteristics of the ISR can not be fully utilized, caused by activating ISR only depending on the EMM combined procedures capability reported by UE. The method comprises: serving general packet radio service (GPRS) support node (SGSN) obtains the subscription data of user equipment (UE); and SGSN activates ISR for the UE when SGSN confirms there is no circuit switch (CS) domain subscription data in the UE's subscription data. Meanwhile, in the present invention other two methods and network devices for confirming ISR activation are also disclosed.
