Embodiment Construction

[0050] The core idea of ​​the present invention is: in WCDMA system, SRNC (Serving Radio Network Controller, service wireless network controller) utilizes the ping packet between it and the base station to obtain the time delay of IUB mouth, and can further according to this time delay or multiple The average delay of the delay and / or the jitter obtained according to multiple delays are used to realize the automatic configuration of the layer 2 parameters of the UU interface.

[0051] Since the WCDMA system uses the transmission delay of a TB (Transport Block, transport block), the delay and jitter detected by the WCDMA system itself are closer to actual requirements.

[0052] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0053] In this embodiment, the SRNC automatically obtains the time delay of the IUB port by calculating the time difference between sending the ping packet and the return of the ping pac...

Abstract

The invention discloses an interface time-delaying obtaining method and device between wireless network controller and base station in the SRNC, which is characterized by the following: sending ping bag for communication mode; recording time T1 of sent ping bag; recording time T2 of returned ping bag; calculating IUB interface time-delaying through time-delaying calculating mode according to T1 and T2. The invention is convenient to obtain IUB time-delaying parameter, which realizes self-allocation of two parameters of UU interface layer.

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 aNode B) interface between RNC (radio network controller) and NODEB (base station) in the WCDMA network, using IP (Internet Protocol, Internet Protocol) transmission is a kind of application that rises recently, and 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 The parameters related to layer 2 of different UU ports will be configured, and operators often do not know the d...
