Method and apparatus for protecting a core network
Abstract:
The present invention provides a method and apparatus for protecting a core network (102) by receiving (202) a message (302, 402) containing a mobile identity of a MS (104) and dropping (210) the message (302, 402) whenever the received mobile identity does not match a stored mobile identity associated with the MS (104). The message (302, 402) is processed (208) whenever the received mobile identity matches the stored mobile identity associated with the MS (104). The mobile identity can be an IMSI, a TMSI or a P-TMSI. The message (302, 402) can be an uplink message (302) or a downlink message (402), such as a Mobility Management (MM) message, a General Packet Radio Service (GPRS) Mobility Management (GMM) message, or a UMA or Unlicensed Radio Resources (URR) message. The present invention can be implemented as a computer program embodied on a computer readable medium wherein the various method steps are implemented by one or more code segments.
Abstract(Chinese):

本发明提供一种用于通过接收（202）包含MS（104）的移动身份并且丢弃（210）消息（302,402）的消息（202,402）来保护核心网络（102）的方法和装置， 每当接收到的移动身份与与MS相关联的存储的移动身份不匹配（104）时。 每当接收到的移动身份与存储的与MS相关联的移动身份（104）匹配时，消息（302,402）被处理（208）。 移动身份可以是IMSI，TMSI或P-TMSI。 消息（302,402）可以是上行链路消息（302）或下行链路消息（402），诸如移动性管理（MM）消息，通用分组无线业务（GPRS）移动性管理（GMM）消息或者 UMA或无证无线电资源（URR）消息。 本发明可以实现为体现在计算机可读介质上的计算机程序，其中各种方法步骤由一个或多个代码段来实现。
