Problems solved by technology

In addition, switching between a large number of systems will increase the load on the core network, and compared with switching between the same systems, the switching time between systems is longer, which will lead to a decrease in user experience
[0036] (3) In the existing protocol process, before parameter negotiation, the cells of two different systems cannot know the parameters related to reselection and the measurement events configured between different systems, and cannot determine the relevant reselection and handover bands.
When parameter adjustment is wrong, it will cause mobility problems such as ping-pong reselection and ping-pong switching, making it difficult for the terminal to connect to any network normally, affecting the normal use of the terminal and reducing the user experience

Embodiment Construction

[0064] An embodiment of the present invention provides a mobility parameter adjustment scheme. In this scheme, the source base station performs parameter evaluation according to the mobility parameters and configuration parameters of the target base station, obtains parameter adjustment suggestion information, and sends the parameter adjustment suggestion information to target base station. The target base station performs parameter evaluation on the received parameter adjustment suggestion information, and sends confirmation information to the source base station when the parameter evaluation is passed. The source base station sends a parameter update notification to the target base station according to the received confirmation information, and adjusts the mobility parameters with the target base station according to the parameter update time carried in the parameter update notification, thereby avoiding ping-pong reselection caused by parameter mismatch, Mobility issues suc...

Abstract

The embodiment of the invention discloses a method and equipment for adjusting mobility parameters. The method comprises the following steps that: a source base station evaluates parameters according to the mobility parameters and configuration parameters of a target base station to acquire parameter adjustment suggestion information, and sends the parameter adjustment suggestion information to the target base station; and the source base station sends a parameter updating notice to the target base station and adjusts the mobility parameters after confirmation information from the target base station is received. By the embodiment of the invention, the success rate of parameter consultation and the convergence of load balancing can be improved.

Description

technical field [0001] The present invention relates to the technical field of mobile communication, in particular to a method and equipment for adjusting mobility parameters. Background technique [0002] With the development of communication technology, reducing the complexity of operation and management work and reducing the cost of operation and maintenance has become an urgent requirement of communication operators. In future mobile communication systems, such as LTE (Long Term Evolution, long-term evolution) systems, by introducing a network self-optimization mechanism, the network automatically optimizes parameters according to statistics, which can reduce manual participation in network planning and operation and maintenance, and reduce network overhead. construction and operating costs. [0003] Based on the above background, 3GPP (3rd Generation Partnership Project, 3rd Generation Partnership Project) integrates SON (Self Organizing Networks, Self-organizing netw...
