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 negotia

Example Embodiment

[0054] Embodiment 1. Routing area update process in Gb mode

[0055] Routing area update in Gb mode includes two situations: routing area update within SGSN and routing area update between SGSNs. These two situations are discussed separately below.

[0056] First, discuss the QoS solution of the routing area update process in the SGSN. In the prior art, if the BSS changes during the update process, the SGSN does not initiate the Packet Flow Context process to notify the new BSS of QoS, which results in inconsistent QoS of network entities. In the present invention, by adding relevant signaling messages in the update process, when both MS and BSS support the Packet Flow Context process, the SGSN initiates the Packet Flow Context process to notify the new BSS of the PacketFlow Id and its corresponding QoS; and, if the new BSS According to its own ability to negotiate to reduce the QoS, the SGSN is responsible for notifying the GGSN and MS of the negotiated reduced QoS. For the speci...

Example Embodiment

[0093] Embodiment 2: Inter-system switching process from Iu mode to Gb mode

[0094] The inter-system handover procedure from Iu mode to Gb mode also includes two situations: the inter-system handover procedure from Iu mode to Gb mode in SGSN and the inter-system handover procedure from Iu mode to Gb mode between SGSN. These two situations are discussed separately below.

[0095] First, discuss the QoS solution for the switching process between Iu mode and Gb mode in SGSN. In the prior art, although the SGSN initiates the PFC process to negotiate QoS with the BSS, if the BSS negotiates to reduce the QoS through the PFC process, other network entities do not respond to this, which will cause the QoS of each network entity to be inconsistent. In the present invention, by adding relevant signaling messages in the handover process, the SGSN will notify the GGSN and MS of the QoS reduced by the BSS negotiation. For the specific signaling process, see Picture 12 , Where signaling 1 to s...

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...
