Problems solved by technology

An increase in the transmit power of the UE will cause stronger interference to other cells
[0004] When the AUE method is applied to indoor coverage cells, the adverse effects caused by the above interference are still within the allowable range of the communication system
However, in the outdoor coverage environment, due to the strong mobility of the user and the rapid change of the channel transmission environment, using the existing AUE method, when the UE is at the edge of the cell, the UE transmit power rises rapidly in a short period of time, causing other cells The interference of the network rises rapidly in a short period of time, causing the call drop rate to increase rapidly, thereby causing the key performance indicators (Key Performance Indicators, KPI for short) of the communication network to decline rapidly

Embodiment Construction

[0037] Due to the strong mobility of the UE in the outdoor coverage environment, when the UE is at the edge of the cell, the transmit power of the UE rises rapidly in a short period of time, causing strong interference to neighboring cells. Based on the above analysis, the following embodiments of the present invention evaluate the UE Whether it is at the edge of the cell, when the UE is at the edge of the cell, the AUE algorithm is turned off to avoid interference to neighboring cells.

[0038] figure 1 It is a flow chart of the AUE method in Embodiment 1 of the present invention. Such as figure 1 As shown, the method includes the following processes.

[0039] Step 101: The RNC acquires the same-and-different-frequency period measurement report reported by the UE.

[0040] Step 102: RNC calculates the received signal code power (Received Signal Code Power, referred to as RSCP) of the Primary Common Control Physical Channel (P-CCPCH) of the local area and the strongest neig...

Abstract

The invention provides a self-adaption uplink enhancement method and a wireless network controller. A different frequency periodic measurement report which is reported by user equipment (UE) is obtained; a P-CCPCH RSCP difference value of a local region and a strongest adjacent region is calculated according to the different frequency periodic measurement report; when a current speed of a packet switch (PS) service is a normal speed and reported sending power exceeds an absolute threshold report incident, and if the P-CCPCH RSCP difference value of the local region and the strongest adjacent region is greater than a matched difference valve threshold, the speed of the PS service ascends to an adaptive uplink enhancement (AUE) speed which corresponds to the current speed. When the current speed of the PS service is the AUE speed, and if the P-CCPCH RSCP difference value of the local region and the strongest adjacent region is less than the matched difference valve threshold, the speed of the PS service descends to the normal speed which corresponds to the current speed. Through the self-adaption uplink enhancement method and the wireless network controller, a key performance indicator (KPI) of a communication network can be improved.

Description

technical field [0001] The present invention relates to mobile communication technology, in particular to an Adaptive Uplink Enhancement (AUE for short) method and a Radio Network Controller (RNC for short). Background technique [0002] The existing AUE method improves PS service throughput and user perception by reducing packet switching (Packet Switch, PS) service channel coding gain. [0003] At the AUE rate, in order to maintain the Quality of Service (QoS for short) required by the PS service, the user equipment (User Equipment, UE for short) will pay extra transmission power. The increase of the transmit power of the UE will cause stronger interference to other cells. [0004] When the AUE method is applied to indoor coverage cells, the adverse effects caused by the above-mentioned interference are still within the allowable range of the communication system. However, in the outdoor coverage environment, due to the strong mobility of the user and the rapid change of...
