Abstract

The embodiments of the present invention provide a method and device for achieving congestion control. The method comprises: determining one or more user equipment required to perform single radio voice call continuity (SRVCC) unloading; and sending an SRVCC unloading message to an evolved Node B (eNodeB) to which the one or more user equipment belongs, so as to enable the evolved Node B to switch the one or more user equipment to a circuit switching (CS) domain from a long term evolution (LTE) domain in the process of triggering the SRVCC switching. In the case of completing the SRVCC switching, the one or more user equipment can be switched to VoCS user equipment from VoLTE user equipment. Thus, the purposes of reducing the load of an LTE cell and guaranteeing the QoS of one or more user equipment can be achieved.

Description

technical field [0001] Embodiments of the present invention relate to the technical field of wireless communication, and more particularly, to a method and apparatus for implementing congestion control. Background technique [0002] With the development of technology, the high bandwidth provided by the Long Term Evolution (Long Term Evolution, "LTE" for short) network brings opportunities for mobile bandwidth to flourish. Compared with LTE data services, LTE-based voice (Voice Over LTE, "VoLTE" for short) has higher resource requirements for wireless coverage. The main reasons are: VoLTE has higher quality-of-Service (QoS) requirements and higher real-time requirements. In addition, VoLTE supports high-definition voice and video encoding and decoding, and has higher bandwidth requirements, so LTE is required. Network resource scheduling prioritizes VoLTE bandwidth occupancy. Based on the above reasons, the increase in the number of VoLTE users will cause the coverage of LT...
