Problems solved by technology

In addition, because the measured value of the power / interference of this cell changes with the service distribution of other cells, the frequency order of this cell will change, which will lead to changes in the service distribution of this cell, which in turn will cause the power / interference of neighboring cells to change. Changes in the interference measurement value and changes in the service distribution of other cells. In this way, the local and neighboring cells affect each other. Therefore, during the adjustment process, oscillation is easy to occur and it is difficult to converge

Embodiment 1

[0041] The present invention can be summarized as following two steps:

[0042] Step 1: Determine which area of ​​the cell the UE is in, that is, the interference zone or the non-interference zone;

[0043] Step 2: After determining that the UE is in the interference band or the non-interference band, use the preferred frequency point set in advance for the interference band or the non-interference band as the UE service frequency point.

[0044] Among them, setting the preferred frequency point for the interference band or the non-interference band can be considered as a part of network planning and network optimization, and can also be considered as a part of RRM (Radio Resource Management, radio resource management) frequency allocation algorithm parameter configuration and optimization. Among them, the allocation of frequency points in the interference band is particularly critical, because the interference band is relatively seriously interfered by adjacent cells, and the...

Embodiment 2

[0071]When the UE accesses the serving cell, the RACH measurement usually only includes the same-frequency measurement results, because it does not include the inter-frequency measurement results, and the RACH has little reference value for determining the UE area at this time. Therefore, steps 201 to 203 in Embodiment 1 may be replaced by the following steps: the RNC randomly selects the UE area, or defaults that the UE is in the interference zone or the non-interference zone. After the UE accesses, it is dynamically adjusted. see image 3 , embodiment two comprises the following steps:

[0072] Step 301: The RNC randomly selects the UE area, including the interference zone and the non-interference zone; or defaults the UE's location, for example, the default UE is in the interference zone, or the default UE is in the non-interference zone; record the area information of the UE;

[0073] Step 302: The RNC initiates the same-frequency and different-frequency measurement cont...

Abstract

The invention discloses a frequency point distribution method which is used in a multi-frequency point time division duplex system. The method comprises the following steps: an RNC (Radio Network Controller) receives same frequency and different frequency measuring results of service cells and adjacent cells reported by UE (User Equipment) and analyzes the measuring results and records of located zones of the UE to confirm the present located zones of the UE, including disturbed belts and undisturbed belts; preset optimal frequency points in the present located zones of the UE are selected based on priority and adopted as UE service frequency points. Based on preventing the service cells from same frequency disturbance of the adjacent cells as much as possible, the invention not only considers the distribution of frequency point resources of local cells, but also considers the distribution of the frequency point resources of the adjacent cells, and selects suitable service frequency points for the UE, thus improving communication quality and finally bringing optimal resource utilization and performance to the whole system. A radio network controller for distributing the frequency points for the multi-frequency point time division duplex system is disclosed either.

Description

technical field [0001] The invention relates to the technical field of network communication, in particular to a method for allocating frequency points applied to a time division duplex system under the condition of multiple frequency points, and a wireless network controller for allocating frequency points. Background technique [0002] Time Division Duplex (Time Division Duplex, TDD) mode refers to a duplex technology for distinguishing wireless channels in time and continuing uplink operation in the downlink operation of the data frame period. One of the development trends of the TDD mobile communication system is to use multi-frequency cell networking. In this way, one serving cell has multiple frequency resources, which provides convenience for frequency bundling and improves the resource utilization and efficiency of the system; and , a user equipment (User Equipment, UE) can receive data from multiple carriers at the same time, can achieve a higher peak rate, multi-ca...
