Problems solved by technology

[0005] The technical problem solved by the solution provided according to the embodiment of the present invention is that when the cross-RAT location area is updated, MME / SGSN and PCRF / PGW / GGSN initiate Qos re-negotiation independently, resulting in a waste of system processing resources

Embodiment Construction

[0060] The preferred embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described below are only used to illustrate and explain the present invention, and are not intended to limit the present invention.

[0061] image 3 It is a flow chart of a method for implementing cross-RAT location area update QoS renegotiation provided by an embodiment of the present invention, as shown in image 3 shown, including:

[0062] Step S301: After the packet data gateway PGW receives the QoS renegotiation indication from the mobility management entity MME, it generates a Qos renegotiation indicating whether the PGW initiates the QoS renegotiation after the cross-radio access technology RAT location area update Initiator message;

[0063] Step S302: MME receives the Qos renegotiation initiator message from PGW, and judges whether PGW initiates Qos renegotiation actively; ...

Abstract

The invention discloses an implementation method and device for updating QoS re-negotiation across RAT location areas, and relates to the technical field of mobile communication. the method comprisesthe steps of generating a QoS re-negotiation initiator message which is used for indicating whether the QoS re-negotiation is actively initiated by the PGW or not after the RAT location area of the cross-wireless access technology is updated after a packet data gateway (PGW) receives the quality of service (QoS) re-negotiation instruction from the mobile management entity (MME), determining whether the PGW actively initiates QoS re-negotiation after the MME receives the QoS re-negotiation initiator message from the PGW, and judges; the MME not actively initiating QoS re-negotiation when judging that the PGW actively initiates QoS re-negotiation; otherwise, the MME actively initiates QoS re-negotiation.

Description

technical field [0001] The present invention relates to the field of mobile communication, in particular to a method for implementing re-negotiation of QoS (Quality of Service) renegotiation across RAT (Radio Access Technology, radio access technology) location areas. Background technique [0002] In order to protect and save investment, the operator's LTE (Long Term Evolution, long-term evolution technology) and 2G / 3G basically coexist, and the operator's EPS (Evolved Packet System, Evolved Packet System) does not introduce IMS (IP Multimedia Subsystem, IP Multimedia Subsystem), using the existing GU (GSM (Global System for Mobile Communications, Global System for Mobile Communications) / UMTS (Universal MobileTelecommunications System, Universal Mobile Communications System)) network, using CSFB (Circuit Switched Fallback, circuit domain fallback) mode Implement voice calls. When the terminal enters the 2G / 3G coverage area from the LTE coverage area or enters the LTE covera...
