Notification method of GPRS tunneling protocol GTP user plane protocol version and device thereof

Abstract

The invention discloses a notification method of a GPRS tunneling protocol GTP user plane protocol version and a device thereof. The method comprises the following steps of: moving a management network element to obtain GTP user plane protocol version information, and sending notification information to network equipment which needs to obtain the GTP user plane protocol version information, wherein the notification information carries the GTP user plane protocol version information. The device comprises an information-obtaining unit and an information-sending unit, wherein the information obtaining unit is used for obtaining the GTP user plane protocol version information; and the information sending unit is used for sending the GTP user plane protocol version information obtained by the information-obtaining unit to the network equipment which needs to obtain the information.

Description

technical field [0001] The invention relates to the technical field of communication, in particular to a method and a device for notifying the version of the GPRS tunnel protocol GTP user plane protocol. Background technique [0002] The network architecture of the next-generation core network SAE (System Architecture Evolution, system architecture evolution) is as follows: figure 1 shown. MME (Mobility Management Entity, mobility management entity) or S4 SGSN (S4 Serving GPRS Support Node, serving GPRS (General Packet Radio Service, general wireless packet service) support node using S4 interface) is responsible for the location management and connection of mobile user terminals Management, security authentication, gateway selection (including selection of serving gateway, data gateway), etc., S-GW (Serving Gateway, serving gateway) is the local access gateway of user terminals, P-GW (Packet Data Network Gateway, packet data network gateway ) is a gateway for user termina...

AI Technical Summary

Problems solved by technology

[0023] In the case of indirect data forwarding, both the source S-GW and the target S-GW only receive the destination address of the forwarded data, and cannot know which GTP user plane protocol version should be selected to forward the data, so it is possible to use Wrong GTP user plane protocol version, resulting in data forwarding failure and data packet loss

[0024] In the case of direct data forwarding, the source network access network element only receives the destination address of the forwarded data, and cannot know which GTP user plane protocol version should be selected to forward the data, so it is possible to use the wrong GTP user The version of the surface protocol, resulting in the failure of data forwarding and the loss of data packets
