Method and system for switching control, user terminal and network device

Abstract

The invention discloses a method and system for switching control, a user terminal and a network device. The method for switching control comprises the steps that after an uplink service is successfully established, UE detects SNPL values with preset detection time serving as a period and identifies whether the SNPL values are smaller than a first preset SNPL threshold value in a 6H event measurement control message issued by the network device in advance; if the answer is positive, a timer is started by the UE to time according to a time period corresponding to triggering delay information in the 6H event measurement control message; if each SNPL value detected in the time period corresponding to the triggering delay information is smaller than the first preset SNPL threshold value, a 6H event measurement report message is sent to the network device by the UE, so that the uplink service on the UE is switched to an appropriate cell and an appropriate frequency point by the network device. According to the method and system for switching control, the user terminal and the network device, the edge service performance of the cell under an uplink high-speed service mode can be improved and the conditions that due to the improvement of the performance, uplink service data sending delay is prolonged or the delay is prolonged too frequently and the cell is updated unnecessarily are avoided.

Description

technical field [0001] The present invention relates to communication technology, especially handover control method and system, user terminal and network equipment. Background technique [0002] Time Division-Synchronous Code Division Multiple Access (TD-SCDMA) is a third-generation wireless communication technical standard. TD-SCDMA High Speed ​​Uplink Packet Access (High Speed ​​Uplink Packet Access, hereinafter referred to as: HSUPA) is an evolution standard of the TD-SCDMA standard, also referred to as TD-HSUPA, or directly referred to as HSUPA. At present, TD-HSUPA business has been widely promoted and applied. [0003] The characteristics of uplink high-speed services will inevitably lead to an increase in the ratio of total received power to noise power (Raise over Terminal, hereinafter referred to as: ROT) and received total wide band power (Received total wide band power, hereinafter referred to as: RTWP) on the network side, especially in When a user equipment (...

AI Technical Summary

Problems solved by technology

[0007] Therefore, the existing technology suppresses the inter-cell interference degree and interference time by controlling the scheduling authorization power and scheduling authorization frequency of the UE, which reduces the service performance, and cannot take into account the transmission delay of uplink service data and prevent too frequent and unnecessary Problems with the cell update process
