Problems solved by technology

[0009] It can be seen from the above process that in the prior art, when a terminal switches between access nodes, the source access node of the terminal generally selects the adjacent access node with the best wireless signal strength as the target access node of the terminal. However, in In a high-speed motion scenario, since the terminal is in a high-speed motion state, when selecting the target access node for the terminal to perform access node switching, the wireless signal gain of each adjacent access node changes very quickly, that is to say, the wireless signal strength changes also Very fast, if still according to the prior art scheme, select the adjacent access node with the best wireless signal strength as the target access node for the terminal to switch the access node, it will make the terminal have to continuously switch the access node, frequently The switching of access nodes not only consumes more processing resources of the terminal and each access node on the network side, but also affects the normal business processing of the terminal.

Embodiment 1

[0082] In the embodiment of the present invention, after the terminal determines the gain change rate of the wireless signal, it reports it to the base station.

[0083] Such as image 3 As shown, when determining the rate of change of wireless signal gain for the terminal, the implementation flow diagram of the node switching method includes the following steps:

[0084] S31. The terminal measures the wireless signal gains of neighboring base stations adjacent to the source base station;

[0085] Specifically, the terminal may perform measurement according to the instruction of the base station, or may periodically measure the wireless signal gains of neighboring base stations adjacent to the source base station, and report the gain to the source base station.

[0086] S32, the terminal judges whether the wireless signal gain of each adjacent base station meets the preset mobile station handover condition, if yes, execute step S33, if not, execute step S31;

Abstract

The invention discloses a node switching method, an apparatus and associated equipment thereof. The method, the apparatus and the equipment of the invention are used to reduce access node switching times, save a processing resource of the each access node of a terminal and a network side. The node switching method comprises the following steps that: a source access node of a mobile station determines the each access node which satisfies a mobile station switching condition when the mobile station needs to carry out the access node switching; the source access node acquires a wireless signal gain change rate of the determined each access node; according to the obtained wireless signal gain change rate, a target access node on which the mobile station carries out the access node switching is selected from the determined each access node; the mobile station is controlled to be switched to the selected target access node.

Description

technical field [0001] The present invention relates to the technical field of mobile communication, in particular to a node switching method, device and related equipment. Background technique [0002] In the prior art, the handover scheme when the terminal performs access node handover is: as long as the handover condition G is satisfied j -G i ≥Γ, the terminal will initiate a handover to the target access node, where G j , G i Represent the wireless signal gain of the target access node and the source access node respectively, Γ is the handover threshold preset to prevent the ping-pong effect when the access node is switched, the source access node is the source base station or the source relay station, and the target access node A node is a target base station or a target relay station. [0003] Such as figure 1 As shown, it is a flow chart of a method for a terminal to switch access nodes in the prior art, and its specific processing flow is as follows: [0004] S...
