Method for setting-up Oos information while quick switching between grouped data service nodes

Abstract

Obtaining message of QoS information, building message of QoS information and updating message of QoS information, the method transfers source QoS information to destination radio network (RN) the mobile terminal is going to switch to, and transfers QoS information allowed by destination RN to source RN so as to ensure consistency of QoS of service before and after switching and allotting resources reasonably. After fast switch over between PDSN occurs at mobile terminal, if mobile terminal initiates new operation application, the destination RN can accomplishes QoS authentication of new built service, admittance control, QoS negotiation, resources allocation, and determines whether access of the new built service is allowed locally based on source QoS information received at the said switching procedure without need of RN side to take part in. advantages are: increasing speed of negotiation, and guaranteeing QoS of service.

Description

technical field [0001] The invention relates to wireless network services, especially a method for establishing quality of service (Qos) information in fast switching between packet data service nodes (PDSN). Background technique [0002] The 3rd Generation Partnership Project II (3GPP2) High Speed ​​Packet Data (HRPD) Rev.0 protocol and 3GPP2 HRPD Rev.A protocol describe when one or more services are in the active (Active) state, the service between PDSN The switching process of the packet domain does not provide the QoS establishment mechanism of the switched service. [0003] From the perspective of PDSN, there are three types of packet domain handover: intra-PDSN handover, inter-PDSN handover, also known as inter-PDSN non-fast handover, and inter-PDSN fast handover. Among them, fast switching between PDSNs is realized through the P-P interface between the source PDSN (Server PDSN) and the target PDSN (Target PDSN), and the target wireless network (Target RN) uses the R-...

Problems solved by technology

[0002] The 3rd Generation Partnership Project II (3GPP2) High Speed ​​Packet Data (HRPD) Rev.0 protocol and 3GPP2 HRPD Rev.A protocol describe when one or more services are in the active (Active) state, the service between PDSN The packet domain handover process, but does not provide the QoS establishment mechanism of the handover service

What is emphasized here is that in the prior art, after a service is quickly switched between PDSNs, if a new service is initiated, a complete Qos negotiation process specified in the protocol needs to be performed. During the Qos negotiation process, the Target PDSN and the Target RN need to obtain the Obtain Qos Profile and Authorize Qos, and then perform Qos authentication and admission control based on the obtained information, which takes a long time

[0036] Judging from the method flow of the above-mentioned prior art, after completing the above-mentioned rapid handover process of the MS between PDSNs, the current agreement does not consider the QoS consistency of the activated service before and after the handover, and there are Target PDSN and Target The RN cannot obtain the source QoS information from the roaming area, so it cannot guarantee the consistency of the service QoS before and after the handover and the reasonable allocation of resources

[0037] In addition, after fast switching between PDSNs, a complete QoS negotiation process is required for new service instances, which takes a long time
