Embodiment Construction

[0051] In view of the problems of poor security and accuracy in the existing APN access restriction methods, the APN access restriction method provided by the embodiment of the present invention, the flow of the method is as follows figure 2 As shown, the execution subject is GGSN, and the specific steps are as follows:

[0052] S20: According to the received PDP connection establishment request message sent by the SGSN, obtain the location information of the user terminal, the identification information of the user terminal and the information of the APN that the user terminal requests to access.

[0053] The SGSN can send a PDP connection establishment request message in two cases. In one case, after receiving the APN access request of the user terminal, it needs to first query the DNS according to the APN to obtain the address of the GGSN, and then send a PDP connection establishment request message; Another situation is that the user terminal is currently accessing the AP...

Abstract

The invention discloses an APN accessing restricting method and a GGSN. The APN accessing restricting method comprises the steps of acquiring user terminal position information, user terminal identification information and APN information which is requested by the user terminal for accessing according to the received PDP connection establishment request information which is transmitted by an SGSN; comparing the user terminal position information, the user terminal identification information and the APN information which is request by the user terminal for accessing with a preset correspondence table, determining whether APN accessing by the user terminal is allowed, wherein the correspondences among the APN information, the area information and the identification information set of the user terminal are stored in the correspondence table; and is APN accessing by the user terminal is not allowed, and transmitting PDP connection establishment refusal information to the SGSN, thereby restricting APN accessing by the user terminal. According to the APN accessing restricting method and the GGSN, restriction precision is refined and safety grade is improved.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to an Access Point Name (Access Point Name, APN) access restriction method and a Gateway General Packet Radio System Support Node (Gate GPRS Support Node, GGSN). Background technique [0002] Mobile operators carry out general packet radio system (General Packet Radio System, GPRS) services, and provide mobile packet Internet protocol (Internet Protocol, IP) connections for user terminals. User terminals access different networks through different access point names (Access Point Name, APN), for example, if a user terminal wants to access the Internet (Internet), it can access the corresponding APN of China Mobile Network (CMNET) / China Mobile Wireless Application Protocol (CMWAP). At the same time, each province of China Mobile will develop some self-owned services according to their own conditions. For these self-owned services, they can also create a special APN to realize ...
