Embodiment Construction

[0042] The method of the invention is applied in the wireless access subsystem of the mobile communication system, and the wireless access subsystem includes wideband code division multiple access WCDMA or time division synchronous code division multiple access TD-SCDMA system UTRAN.

[0043] The method of the invention includes: sending the IP message sent to the mobile user terminal to the user plane entity of the wireless access subsystem, and the user plane entity implements IP QoS control on the received IP message according to the selected IP QoS service model. It also includes sending a signaling message of the IP QoS policy by the core network to the control plane of the wireless access subsystem, converting the QoS control parameters carried in the signaling message into transmission parameters of the wireless channel corresponding to the user plane by the control plane, and A corresponding wireless channel is configured by using the transmission parameters, and the co...

Abstract

The method comprises: the IP message sent to the mobile user end is transmitted to the user plane entity (UPE) of radio access subsystem; the UPE makes IP QoS control for the IP message according to the selected IP QoS service model. It also comprises: the core network sends IP QoS strategy signaling message to the control plane of the radio access subsystem that converts the QoS control parameters carried by said signaling message into the transmission parameters of radio channel corresponding by user plane; said transmission parameters are used to configure relevant radio channel that is used to bear and receive the IP message.

Description

technical field [0001] The present invention relates to the field of wireless communication, in particular to an IP quality of service (Quality of Service, QoS) control method in a universal mobile communication system terrestrial radio access network (Universal Terrestrial Radio Access Network, UTRAN). Background technique [0002] The PS Domain (PS Domain) ), providing packet access services in their UTRAN. The current IP protocol is popular in the network, and the packet switching domain mainly transmits IP packets. In the future, the entire UTRAN will evolve to carry all IP services. The protocol structure of downlink IP packet transmission in UTRAN of WCDMA and TD-SCDMA is as follows: figure 1 shown, including: [0003] Packet Data Convergence Protocol (PDCP): Provides functions such as transmission and compression of IP packets on radio bearers, and support for relocation of Serving Radio Network Controller (SRNC) without loss. In this protocol structure, only the ...
