  • Patent number: 8732799
    Abstract: The disclosure provides a method and a system for processing an authenticator relocation request. When detecting that initial authentication, re-authentication or authenticator relocation is being performed for a terminal, a network side refuses a new authenticator relocation request from the terminal. When detecting that no initial authentication, re-authentication or authenticator relocation is being performed for the terminal, the network side accepts the new authenticator relocation request from the terminal. Further, when detecting that the initial authentication, the re-authentication or the authenticator relocation is being performed for the terminal, the network side refuses a new re-authentication request from the terminal. According to the technical solution of the disclosure, the complexity of network element processing is reduced and potential safety hazard is avoided.

  • Patent number: 8660048
    Abstract: The present invention discloses a method for scheduling wireless resources of a multi-base station MBS and a method for sending occupation information. The scheduling method comprises: dividing wireless resources of downlink sub-frames of all base stations in an MBS Zone into two parts, local service schedulers on the base stations scheduling one part for local services, and a multi-base station MBS resource scheduler in the MBS Zone scheduling the other part for the multi-base station MBS. The sending method comprises: a sender informing a receiver of multi-base station MBS wireless resource occupation situation through a message carrying multi-base station MBS wireless resource occupation information; the occupation information including configuration information and a scheduling result. When supporting the macro diversity multi-base station MBS, the present invention not only can avoid the conflict of unicast and MBS scheduling, but also can fully utilize the limited wireless resources of the system.

  • Patent number: 8320316
    Abstract: A method for accelerating network accessing of a terminal in a wireless communication system, comprises: a wireless terminal receiving system parameter information, and after obtaining system information of a base station identifier (BS ID) and a network access provider identifier (NAP ID), immediately judging validity of the NAP ID, or validity of both the NAP ID and the BS ID; if a result of the judgment is “valid”, the terminal proceeding to a subsequent procedure of the network discovery and selection according to information stored in the terminal, otherwise, carrying out a new procedure of network discovery and selection. The method avoids continuing to perform processes such as message receiving and decoding in the case that a NAP ID or a BS ID is invalid according to a procedure in the current protocol, thereby increasing the speed of network accessing of a terminal.
