Embodiment Construction

[0023] The following is attached Figure 1~2 The method for automatically assigning scrambling codes of the present invention is described in detail.

[0024] The method for automatically distributing scrambling codes of the present invention comprises the following steps:

[0025] Step 100: After the HOME-NODEB is powered on, it automatically searches for neighbor cell information, and reports the neighbor cell list and scrambling code information to the RNC;

[0026] Step 200: The RNC records the neighbor cell list and scrambling code information reported by each HOME-NODEB and the time reported by each HOME-NODEB, and then selects the corresponding scrambling code for allocation according to the recorded information.

[0027] Wherein, step 200 includes the following steps:

[0028] Step 201: Predefine an information queue with variable length and a sliding time window TimeWinSize in the RNC, wherein the information queue is used to store the scrambling code information al...

Abstract

The invention provides an automatic distribution method for scrambled code, including the following steps: A adjacent area information is searched after HOME-NODEB is started and adjacent area list and scrambled code information is reported to a wireless network controller RNC, step B RNC records the adjacent area list and the scrambled code information, which are reported by each HOME-NODEB and each report time of HOME-NODEB and then chooses corresponding scrambled code to distribute according to the record information. The automatic distribution method for scrambled code of the invention can effectively reduce the work load for background network management configuration and respond to users' requirement more agilely.

Description

technical field [0001] The invention relates to an automatic scrambling code distribution method in a family-level Nodeb network in a Wideband Code Division Multiple Access (WCDMA) system. Background technique [0002] At present, miniaturization, high power and wide coverage are the development trends of base stations. The home-type base station product HOME-NODEB is a hot research topic at present. Especially in the 3G era, in order to support high-speed data services, high capacity will become one of the main features of the new generation of base stations. At the same time, base stations must improve processing capabilities; due to dense distribution, base stations will tend to be more miniaturized and integrated; considering the surrounding residents Due to the influence of radiation, the base station should reduce the total transmission power and do a good job of indoor coverage. The introduction of HOME-NODEB can effectively realize the integration of fixed network ...
