Mobility parameter negotiation method and device thereof

Abstract

The invention discloses a mobility parameter negotiation method and a device thereof, wherein the method comprises: a target base station receives mobility parameter negotiation request information sent by a source base station, wherein the mobility parameter of a source cell after planning and adjustment is carried; and the target base station determines whether ping-pong switching is caused between the source cell and a target cell according to the mobility parameter of the target cell after planning and adjustment and the mobility parameter of the source cell after planning and adjustment, refuses the mobility parameter negotiation request of the source base station when the determination is yes, and then returns the mobility parameter negotiation refused response information to the source base station. The ping-pong switching can be avoided by adopting the mobility parameter negotiation method and device thereof provided by the invention.

Description

technical field [0001] The invention relates to the communication field, in particular to a mobility parameter negotiation method and equipment thereof. Background technique [0002] The network self-optimization function is introduced into the LTE (Long Term Evolution, long-term evolution) system, that is, the system automatically optimizes the corresponding parameter configuration according to the network performance, thereby reducing manual participation in network planning and operation and maintenance, and reducing network construction and operation costs. Among them, Mobility Load Balance (MLB) is an important example of self-optimization of self-organizing networks (Self Organizing Networks, SON). The principle of load balancing is to adjust the handover and reselection parameters of the cell and the corresponding neighboring cell, such as figure 1 As shown in Fig. 1, the edge users of the heavy-loaded cell are transferred to the light-loaded neighboring cell as much...

AI Technical Summary

Problems solved by technology

[0006] In the above process, the target base station can only decide whether to accept the sender’s suggested value for adjusting the mobility parameter or give a new recommended value for adjusting the mobility parameter according to the range of mobility parameters or the load of its own cell, which cannot effectively avoid the adjustment. After the mobility parameter setting will not cause ping-pong handover

[0007] If the mobility parameters are not set properly, it is easy to cause ping-pong switching

In this way, it not only reduces the user experience, but also wastes system resources, which violates the original intention of mobility load balancing, that is, the overall performance of the network is not only not optimized but deteriorates.
