Problems solved by technology

If in the PDP context activation process, after the MS successfully returns the PDP context activation request message to the SGSN, the activation fails due to some reasons of the SGSN on the network side, such as insufficient user plane resources, and the SGSN has no corresponding process to notify the GGSN. As a result, the GGSN cannot discard or reject received data packets in time for protection processing

Embodiment Construction

[0033] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0034]The method for implementing the PDP context activation process provided by the present invention triggers the PDP context activation process on the network side, and after the MS receives the PDP context activation request message sent by the network side, and returns the PDP context activation request message to the SGSN; or, the terminal triggers the PDP context activation request message. In the context activation process, after the MS sends a PDP context activation request message to the SGSN, the network side determines whether the system is faulty, and if so, adds a cause value that can be carried in the packet domain data packet notification rejection request message of the existing protocol process, If the system fails, etc., ...

Abstract

The invention discloses a method to achieve grouped realm data negotiate context to activate process, the method informs rejective request message in virtue of grouped realm data the existing GGSN send to SGSN, by increasing the reason value the information carries, expand the serviceable range of grouped realm data informs rejective request message process in existing negotiated process, the SGSN still be able to promptly notify the GGSN to refuse or discard packets when fails to activate PDP context as a result of network side, , not only reduce the burden on the GGSN, but also guarantee the integrity that the network side or terminal triggered PDP context activate process.

Description

technical field [0001] The invention relates to a general wireless packet network technology, in particular to a method for realizing the context activation process of a packet domain data protocol. Background technique [0002] With the high-speed growth of data switching services, the Global System for Mobile Communications (GMS) based on circuit switching is increasingly unable to meet the needs of users, so the General Packet Radio Service (GPRS) network featuring packet switching has emerged. Referring to Fig. 1, Fig. 1 has provided the group network structural diagram of GPRS network, as can be seen from Fig. 1, GPRS network mainly comprises: GPRS Service Support Node (SGSN) 101, GPRS Gateway Support Node (GGSN) 102, packet domain Data Network (PDN) 103 , Home Location Register (HLR) 104 . Among them, the GGSN is connected to the SGSN through the Gn or Gp interface, and connected to the PDN through the Gi interface. The GGSN is mainly used to provide routing and encap...
