Embodiment Construction

[0024] Hereinafter, the present invention will be described in detail with reference to the drawings and examples. It should be noted that, in the case of no conflict, the embodiments in the present application and the features in the embodiments can be combined with each other.

[0025] figure 2 is a flowchart of a handover method based on congestion control according to an embodiment of the present invention. Such as figure 2 As shown, the handover method based on congestion control mainly includes the following processing:

[0026] Step S202: The terminal receives status information and congestion trigger indication information broadcast from the serving base station;

[0027] Step S204: The terminal determines whether the serving base station is in a congested state according to the state information;

[0028] Step S206: When the serving base station is in a congested state, the terminal performs an operation corresponding to the congestion trigger indication informa...

Abstract

The invention discloses a switching method and system based on congestion control. The method comprises: the terminal receives the state information broadcast by a service base station and the congestion trigger indicating information; the terminal determines whether the service base station is in a congestion state or not according to the state information; and the terminal executes the operation corresponding to the congestion trigger indicating information when the service base station is in the congestion state. The technical scheme provided by the invention has the advantages that the interactive steps of the terminal and the base station are reduced and the working procedure of the service base station in the congestion state is lightened so as to greatly enhance the timeliness of solving the congestion.

Description

technical field [0001] The present invention relates to the communication field, in particular, to a congestion control-based switching method and system. Background technique [0002] In a common wireless communication system, due to various factors such as mobility, signal variability, and business diversity, the system may often experience congestion. For the Worldwide Interoperability for Microwave Access (Wimax) system, due to the introduction of technologies such as Adaptive Modulation Coding (AMC) and power control, users or terminals can At the same time, WiMAX supports multiple types of services. These factors may lead to huge fluctuations in the capacity of the entire air interface, greatly increasing the possibility of congestion. When congestion occurs, the general approach is as follows: deny access to new users or new connections, or release currently accessed users or connections. A better way is as follows: the base station triggers the handover process for...
