Embodiment Construction

[0021] Considering that the DRNC is not directly connected to the CN corresponding to the user, it cannot directly initiate Qos renegotiation, but only the SRNC can. Therefore, when the DRNC needs to initiate a renegotiation, it first notifies the SRNC through the Iur interface, and the SRNC triggers the communication with the CN. Qos re-negotiation process.

[0022] Such as figure 1 As shown, the process of triggering Qos re-negotiation across the Iur interface by the DRNC includes:

[0023] Step 101, in the process of establishing a service of the user equipment UE, the SRNC records information related to Qos negotiation assigned by the CN (hereinafter referred to as Qos negotiation information), such as an optional guaranteed rate list (Alternative Guaranteed Rate List) and / or Optional list of max rates;

[0024] The optional guaranteed rate list includes one or more selectable guaranteed rates; the optional maximum rate list includes one or more selectable maximum rates....

Abstract

The invention provides a quality of service renegotiation method in order to solve the technical problems so that a DRNC can span an Iur interface to trigger Qos renegotiation. The method comprises that: in the process that UE establishes service, an SRNC records Qos negotiation information designated by a CN; when the UE in a cell administered by the DRNC establishes a wireless link or newly establishes service on a wireless link of the existing Iur interface, the SRNC sends the Qos negotiation information of the service to the DRNC; when the DRNC discovers that the cell of the wireless linkis over-loaded or has congested resources and needs to adjust the resource occupied by the service, the DRNC reselects a Qos negotiation parameter according to the recorded Qos negotiation information, and informs the SRNC of the reselected Qos negotiation parameter; and after receiving the Qos negotiation parameter sent by the DRNC, the SRNC initiates a Qos renegotiation flow to the CN.

Description

technical field [0001] The invention relates to a wireless cellular communication system, in particular to a Qos (Quality of Service, service quality) renegotiation method in a WCDMA mobile communication system. Background technique [0002] In the WCDMA mobile communication system, Qos negotiation and Qos re-negotiation mechanisms are provided for service establishment and maintenance between CN (core network) and RNC (radio network controller) (Iu interface). The so-called Qos negotiation refers to: CN assigns multiple Qos in the process of establishing a service, and the RNC can select a suitable Qos to establish a service according to the capability and load of the wireless access network. The so-called Qos re-negotiation refers to: under the premise that CN assigns multiple Qos during the service establishment process, in the process of service operation, because the capability or load of the wireless access network changes, it is desired to change the Qos of the servic...
