Problems solved by technology

[0073] The main reason for this situation is that, on the one hand, for NBAP, the scrambling codes of E-AGCH, E-RGCH and E-HICH cannot be independently selected by Node B but allocated by RNC, and the return of this IE by Node B may cause E -The wrong scrambling code allocation of AGCH, E-RGCH and E-HICH also increases the useless message content of NBAP and RNSAP, and the correctness of wireless link downlink control channel configuration cannot be guaranteed, resulting in potential problems

Embodiment Construction

[0102] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0103] Fig. 5 shows a flowchart of a method for configuring an E-DCH radio link according to an embodiment of the present invention.

[0104] First, at step 510, when establishing a cell, the RNC pre-configures at least one reference channel and its corresponding scrambling code in the Node B.

[0105] Thereafter, in step 520, the Node B uses the scrambling code corresponding to the reference channel of the E-DCH radio link to configure the radio link. This process includes the establishment of the E-DCH radio link, or the addition of the E-DCH radio link , or reconfiguration of the E-DCH radio link, or deletion of the E-DCH radio link. Moreover, in the configuration process of this step, the scrambling code used for sending the E-DCH radio link downlink control ...

Abstract

The disclosed method guarantees correctness of configuring E-DCH down going control channel. In the invention, Node B prevents scrambling codes of E-AGCH, E-RGCH, and E-HICH from informing to RNC. If requiring using scrambling codes of E-DCH down going control channel, RNC directly queries scrambling codes corresponding to reference channel of relevant wireless link stored locally so as to stop possibility of misusing scrambling codes transferred from Node B radically. The invention prevents error possible to be introduced by Node B in processing procedure, and in procedure of transferring scrambling codes from Node B to RNC. In addition, reducing information sending to RNC from Node B, the invention raises efficiency of transferring NBAP / RNSAP message correspondingly.

Description

technical field [0001] The present invention relates to the field of mobile communication, in particular to an enhanced dedicated channel (Enhanced Dedicated Channel, referred to as "E-DCH") wireless link configuration technology. Background technique [0002] The Universal Mobile Telecommunications System ("UMTS") is a global system for mobile communications (Global System for Mobile communication, "GSM") network proposed by the European Telecommunications Standards Institute ("ETSI"). Solutions based on a smooth transition to the third generation of mobile communications. In essence, it is the third generation mobile communication system. [0003] UMTS is compatible with the existing legacy GSM system. The GSM system will transition to UMTS in stages. The General Packet Radio Service (GPRS) that has been launched now provides connectionless services to the GSM network, expands the service functions and flexibility of the GSM system, and improves the transmission rate of...
