Embodiment Construction

[0043] In order to solve the above problems, the embodiment of the present invention proposes a terminal network attachment scheme, which checks the resources of the internal network elements of the core network through PING packets, and releases abnormal resources, so as to solve the problem of different Resource inconsistency between network elements.

[0044] 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. Obviously, the described embodiments are only some embodiments of the present invention, rather than all embodiments . Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

Abstract

The embodiment of the invention discloses a terminating network attaching method and device. The method comprises the steps that a PGW receives a terminating network attaching request message; the PGW allocates a resource to a terminal requesting for network attachment according to the terminating network attaching request message, feeds back a network attachment response message, and sends a PING message used for detecting tunnel information of the terminal; if the PGW receives a response message of the PING message, the source allocated to the terminal is kept; if the PGW receives an error indication message fed back by a service gateway (SGW), the source allocated to the terminal is released. The terminating network attaching method and device can solve the problem that resources on different network elements in a core network are nonuniform under the situation that terminating network attachment fails.

Description

technical field [0001] The present invention relates to the communication field, in particular to a terminal network attachment method and equipment. Background technique [0002] Under LTE (Long Term Evolution, long-term evolution), once the response message from the back-end network element to the front-end network element is lost during the user's Attach (attach) access process, resource inconsistencies will occur in each network element in the core network . [0003] Usually, the normal Attach process is as follows figure 1 As shown, the network elements involved may include: eNB (evolvedNodeB, evolved Node B, i.e. base station), MME (Mobile Management Entity, mobile management entity), SGW (Serving Gateway, serving gateway), PGW (PDN Gateway, PDN gateway ;PDN: Packet Data Network, PCRF (Policy and Charging RulesFunction, policy and charging rule functional unit), HSS (Home Subscriber Server, home user server), EIR (Equipment Identity Register, equipment identification...
