Problems solved by technology

[0004] However, in the prior art, the base station side only uses the signal quality as the judgment criterion for handover. If the load of the target cell after handover is already heavy, then handing over the user to the target cell will cause the load of the target cell to be too large, which will reduce the load on the contrary.

Embodiment Construction

[0019] figure 1 It is a flowchart of the first embodiment of the inter-system switching method of the present invention, as shown in figure 1 As shown, the inter-system handover method provided by the embodiment of the present invention is executed by the inter-system handover device, which is installed between the core network of the first network and the core network of the second network, and serves as a link between the first network and the second network. public. The terminal is handed over from the source cell of the second network to the target cell of the first network with better network resources. The inter-system switching device can be implemented in the form of software and / or hardware, and the method includes:

[0020] Step S100, acquiring a network access request for a terminal to access the first network;

[0021] A terminal in a connected state in the second network, when initiating a service, sends a network access request to the inter-system switching de...

Abstract

The invention provides a method and a device for switching inter-systems. The method comprises the following steps of: acquiring a network access request for access of a terminal into a first network; according to the network access request, acquiring the load information of a target cell in the first network; and when the load information of the target cell exceeds a load threshold value, according to the service priority of the terminal and the service priority of an edge user in the target cell, switching the edge user with low service priority into a cell of a second network, and accessing the terminal into the target cell. When a network load is high and the service priority of the terminal is high, a switching scheme for inter-system switching is optimized in a mode of switching the edge user into the second network and then accessing the terminal into the first network, and the utilization effect of network resources is improved.

Description

technical field [0001] The invention relates to wireless network communication technology, in particular to a method and device for switching between different systems. Background technique [0002] Inter-system handover means that the terminal crosses the existing network boundary, switches services from one network to another network, and uses the switched network to manage current services after the network switch is completed. For example, in a network where Long Term Evolution (LTE for short) coexists with Global System for Mobile Communications (GSM for short) or Universal Mobile Telecommunications System (UMTS for short), the terminal is in In the connected state and there are services in progress, in order to maintain the communication quality of the terminal, the terminal needs to switch from the source base station of the GSM / UMTS network to the target base station of the LTE network with better signal quality. [0003] Handover between different systems is a key ...
