Problems solved by technology
[0006] From the above analysis, it can be seen that the problem in the prior art solution is: the mutual access between mobile terminals under the same APN (or NSP) does not go through the operator's gateway, and the security of the mobile terminal itself is not high. Therefore, the same APN Virus transmission and network attacks between mobile terminals under (or NSP) can bypass the operator's gateway and pose threats to user security and mobile network operations

Embodiment Construction
[0033] The present invention will be described in further detail below with reference to the accompanying drawings and in combination with specific embodiments.
[0034] In order to prevent mutual attacks between mobile terminals, there must be a method capable of controlling mutual access between mobile terminals under the same service point (which can be APN or NSP). For this reason, the present invention provides a set of mutual access control on the mobile core network The rules are for operators to choose and configure: (1) Allow MSs under the same APN (or NSP) to visit each other; (2) Forbid MSs under the same APN (or NSP) to visit each other, that is, discard MS mutual visit messages; ( 3) Redirect the MS mutual access message under the same APN (or NSP) to the operator's gateway, and the gateway decides to forward or discard the message. When mobile terminals under the same APN (or NSP) access each other and the message arrives at the GGSN (or AGW), the GGSN (or AGW) d...

The invention discloses a method and a system for preventing mutual attack between mobile terminals in a mobile network. The method comprises the following steps that: A, a control rule for mutual access of the mobile terminals is configured on a core network; B, the mobile terminal of a transmission side transmits a message to a user plane unit of the transmission side; C, the user plane unit ofthe transmission side determines that whether the target address of the message and the address of the mobile terminal of the transmission side belong to the same virtual routing space or not, if so,a service point label of the mobile terminal of the transmission side and a virtual routing space label are encapsulated for the message, and the message is forwarded to the user plane unit of a receiving side; and D, the user plane unit of the receiving side determines that whether the mobile terminal of the transmission side and the mobile terminal of the receiving side belong to the same service point or not according to the service point label and the virtual routing space label in the encapsulated message, if so, the encapsulated message is subjected to corresponding processing accordingto the control rule. The method and the system can effectively control mutual access between the mobile terminals, and enhance security of the mobile network.
Description
technical field [0001] The invention relates to a wireless communication system, in particular to a method and system for preventing mobile terminals from attacking each other in a mobile network. Background technique [0002] With the development of mobile networks, the security of mobile networks has drawn more and more attention. Compared with the Internet, due to the relatively long history of the Internet, many security tools and strategies have been born in the process of network security games between viruses and anti-viruses, attacks and anti-attacks, both in terms of operators and Internet terminals (mainly referring to personal computers) All aspects have a relatively complete security policy, thus providing a good guarantee for the operation of the Internet; and in the mobile network, although the operator has a better security policy, but in the mobile terminal (Mobile Station, referred to as MS) , due to the limitations of the mobile terminal's own hardware and...
