Problems solved by technology

[0004] From the above existing technologies, it can be seen that due to soft handover, there are multiple RLs in the UE, and the signal coverage of the cell is uneven, which leads to poor uplink quality of the RL. After the base station detects a wireless link with poor uplink quality, it will Report to the wireless network controller. Under the existing mechanism, if the recovery instruction is not received before the timer expires, the wireless network controller will send a request to delete the current wireless link, so that the wireless link with poor uplink quality will be deleted. causing users to drop calls

Embodiment Construction

[0014] The present invention provides a method for solving call drop and a wireless network controller, the core idea of ​​which is that the wireless network controller judges whether the number of uplink out-of-synchronization wireless links is less than the specified The number of wireless links recorded by the terminal, if so, keep the wireless link to continue communication; use the link with good uplink quality and poor downlink quality when data is uplink, and use the link with good downlink quality and uplink quality when data is downlink Links with poor quality can avoid terminal call drop and improve network quality.

[0015] Please refer to figure 2 , is a flow chart of a method in an embodiment of the present invention.

[0016] Step 21. The terminal updates the wireless link.

[0017] In a mobile communication system, since adjacent cells have the same frequency, the UE can communicate with the network through multiple wireless links. When multiple wireless lin...

Abstract

This invention discloses one method and wireless network controller to solve drop method, which comprises the following steps: after receiving terminal drop message in wireless linkage for wireless network controller judging the above loss number is larger than terminal record wireless linkage number; if yes, keeping the wireless linkage; in data upper linkage, using linkage with good upper quality and down bad quality while the reverse in data down layer.

Description

technical field [0001] The invention relates to the field of mobile communication, in particular to a method for solving call drop and a wireless network controller. Background technique [0002] The signal coverage of the cell is uneven or the terminal (UE) moves, and the signal quality of the cell in the UE active set is constantly changing. The active set is a set of cells that the UE is communicating with, and the monitoring set is likely to enter the UE active set. A collection of neighborhoods. Due to the increase of soft handover radio links, the UE may have multiple radio links (RL) in the current active set, and the UE may use the multiple radio links RL to communicate with the network to improve communication quality. [0003] However, when the RL uplink and downlink voice quality has problems, it may cause users to drop calls. The main scenario is that there are multiple radio links in the UE. Please refer to figure 1 , during soft handover, the UE generates t...
