Embodiment Construction

[0032] The present invention makes full use of the measurement results reported by Node B in the WCDMA system. In the RNC, according to the reported load of the current cell and the load of the same-coverage and different-frequency cells, it is comprehensively determined whether it is necessary for the UE in service communication to be balanced to other cells. Different carriers and frequencies cover the same cell.

[0033] Below in conjunction with accompanying drawing, the implementation of technical scheme is described in further detail:

[0034] When the method of the present invention is applied in the WCDMA system, in the measurement control command, the periodic reporting scheme is adopted for public measurement, and it also has important reference significance for the event-triggered reporting method.

[0035] The flow process of method core idea of ​​the present invention is as figure 1 shown, from figure 1 As can be seen:

[0036] Step 101, RNC sends common measur...

Abstract

The invention discloses a frequency-frequency load balance controlling method in wideband code division multiple access (CDMA) system, including the following processing steps: RNC obtains information reflecting village load status at regular intervals; RNC determines if it is necessary to execute balancing action according to preset load threshold parameters, actually-measured village load and same-covered different frequency village load: if yes, select partial UEs from the different-frequency village and send frequency-frequency hard switching command to these UEs; the UEs executing switching return finish information in the different frequency village. The invention can perfectly assure WCDMA system selects partial UEs to switch to lower- load same-covered different frequency village so as to receive service as soon as possible in the operating course, thus better realizing laod balance and maximumizing the whole system capacity and can also be convenient for the connection of follow-up UE.

Description

technical field [0001] The invention relates to a load balancing method in a Wideband Code Division Multiple Access (WCDMA) system (hereinafter referred to as WCDMA), especially according to the load measurement value of a cell and its same coverage cell, that is, using the received total broadband power (Received Total Wide Band Power) (hereinafter referred to as RTWP) and / or Transmitted Carrier Power (hereinafter referred to as TCP) to determine the specific method of inter-frequency load balancing control during system operation. Background technique [0002] With the wide application and rapid development of mobile communication systems, many key technologies in mobile systems are becoming more and more perfect. While realizing normal communication of users, it is also necessary to consider how to obtain the best performance, and obtain the best performance for both the system and user equipment. Better satisfactory results, from the perspective of the system, it is hope...
