Method for ensuring service quality consistency of network each entity

Abstract

The present invention disclose ensuring network each entity service quality concordant method. Said method includes mobile station MS originating routing area updating or intersystem switching request to SGSN, and to make routing area updating or intersystem switching; judging base station system BSS service quality QoS whether generating variation, if is then SGSN notifying network supported QoS to network entity; otherwise judging GGSN QoS whether generating variation, if is then SGSN notifying variational QoS to network other entity; otherwise ending said process. Said invention provided method can ensure network entity QoS concordance in network entity and / or network entity QoS variation.

Description

technical field [0001] The invention relates to the field of mobile communication, in particular to a method for ensuring consistent service quality of each entity in the network. Background technique [0002] In the network of General Packet Radio Service (GPRS, General Packet Radio Service) or Universal Mobile Telecommunications System (UMTS, Universal Mobile Telecommunications System), the Serving GPRS Support Node (SGSN, Serving GPRS Support Node) is the packet domain core network (CN, The main equipment of Core Network) mainly completes the routing and forwarding of packet data packets, encryption and authentication, session management, mobility management, logical link management, bill generation and output and other functions. The position of SGSN in the mobile communication network is as follows: figure 1 It can be seen from the figure that the SGSN uses different interface protocols to connect with other devices or networks. Among them, the mobile station (MS, Mob...

Problems solved by technology

[0016] From the above process, it can be seen that in this inter-system handover process, after the new side SGSN sends the Update PDP Context Request message carrying QoS to the GGSN, the GGSN may negotiate to reduce the QoS according to its own capabilities, and the Update PDP Context Response message However, the new side SGSN does not further notify other network entities of the updated QoS, so it will lead to inconsistencies among network entities

In addition, after the inter-system handover process is completed, although the new SGSN will initiate a PFC process to negotiate QoS with the BSS, if the BSS negotiates to reduce the QoS, other network entities will not respond to this, which will also cause network entities to fail. Inconsistent QoS

[0017] Based on the above, it can be seen that whether it is routing area update or inter-system handover, the movement of the mobile station may cause changes in the network entity and / or the QoS of the network entity, which may lead to inconsistent QoS of the network entities in the system. Therefore, the user's Service quality may not be guaranteed, and may cause unnecessary waste of network resources
