Method and apparatus for obtaining interface time delay between wireless network controller and base station

Abstract

The invention relates to a method for obtaining the interface time delay between wireless network controller and the base station, and relative device. Wherein, said device is use din SRNC; when the communication module receives the ascending node synchronous message feedback from base station, the record sub module will record the time T4 that the communication module receives said message; the time delay calculate sub module, according to the time T1 that communicated module sends descending node synchronous message to base station that carried in the ascending node synchronous message of communication module, the time T2 that base station receives the descending node synchronous message, the time T3 that the base station feeds back said ascending node synchronous message to communication module, and the time T4 recorded by record sub module, calculates the time delay of IUB port. With said invention, the time delay factor of IUB port can be automatically obtained, and the vibration of IUB port can be calculated according to said time delay, and based on the time delay and / or vibration, UU port layer 2 factors can be automatically arranged.

Description

technical field [0001] The present invention relates to WCDMA (Wideband Code Division Multiple Access, wideband code division multiple access) technology, in particular to a method and device for acquiring interface time delay between a wireless network controller and a base station. Background technique [0002] On the IUB (Interface between an RNC and a Node B) interface between the RNC (Radio Network Controller) and the NODEB (Base Station) in the WCDMA network, using IP (Internet Protocol, Internet Protocol) transmission is a recently emerging application. The delay and jitter introduced by IP transmission have a profound impact on the parameter configuration of layer 2 of UU (The Radio interface between UTRAN and the User Equipment, the interface between the access network and the terminal) involved in typical WCDMA services. Different delays and Jitter will configure different parameters related to layer 2 of the UU interface, and operators often do not know the delay ...
