Problems solved by technology

[0019] In practical application, the above scheme has the following problems: Since the CDMA network is designed as a synchronous system, it only needs to do a little processing on the GPS signal to obtain a synchronous signal with a period of 2s, while WCDMA is designed as an asynchronous network, so the base station of CDMA Synchronization technology cannot be applied to WCDMA
Therefore, effective BFN synchronization cannot be performed in the current WCDMA system, which affects the handover success rate and system capacity of the UE, and the handover process of the UE is complicated, and the power consumption of the mobile phone is relatively large
[0020] The main reason for this situation is that there are differences in synchronization standards between WCDMA and CDMA technologies

Embodiment Construction

[0048] 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.

[0049] In general, the principle of the present invention is that the base station converts the corresponding BFN count value according to the GPS absolute time from the GPS satellite receiver as the current BFN count value. And through regular inspection, if the actual value is inconsistent with the required value, replace it with the converted BFN count value. Thus, the BFN synchronization of the Node B in the WCDMA system is realized, the handover success rate and service quality are improved, and the power consumption of the UE is also saved.

[0050] Combine below figure 2 , illustrating the structure and working process of the BFN synchronization system between Node Bs in the WCDMA system according to an embodiment of the present invention.

Abstract

A method for synchronizing B node frame number between base stations in wideband CDMA system includes converting out relevant BFN counting value by base station according to GPS absolute time obtained by GPS satellite receiver from GPS signal, using converted out BFN counting value as current BFN counting value and carrying out inspection on it regularly, replacing actual value to be converted out BFN counting value when actual value is not consistent to required value.

Description

technical field [0001] The present invention relates to the communication field, in particular to a Node B Frame Number (Node B Frame Number, "BFN" for short) synchronization technology in mobile communication. Background technique [0002] In the past 20 years, the development of mobile communication technology has gone through two generations, from the first generation of analog cellular communication technology to the second generation of digital communication represented by Global System for Mobile Communications (Global System for Mobile Communications, referred to as "GSM") technology transition. Now it is developing towards the third generation mobile communication system (Third Generation Mobile Communications System, referred to as "3G"). Among them, Wideband Code Division Multiple Access ("WCDMA") technology, as one of the main 3G standards stipulated by the International Telecommunication Union ("ITU"), is a mainstream technology for 3G development.
