Problems solved by technology

Since the UE's signal at the S-eNB is already poor, and there is a problem that unicast cannot cover the UE, which leads to the failure of the establishment of unicast at the S-eNB, and it is difficult to ensure service continuity
[0006] Furthermore, if the UE receives the service through the unicast bearer at the S-eNB, although the T-eNB uses the multicast / multicast bearer to realize the service, after the UE accesses the T-eNB, if it wants to receive data through the multicast / multicast bearer , business continuity is usually not guaranteed

Embodiment Construction

[0107] Embodiments of the present invention provide a user equipment handover method and a base station. When the target base station determines that the UE needs to be handed over from the source base station to the target base station, and needs to switch between a unicast bearer and a groupcast / multicast bearer, due to the The progress of sending data packets in the original bearer may be less than the progress of sending data packets in the original bearer, so the target base station receives the data packets sent by the original bearer and the target bearer at the same time. When the progress of receiving the data packet in the bearer, the UE is switched to the target bearer, thereby improving the service continuity during the UE handover process.

[0108] Such as figure 2 As shown, the user equipment handover method provided by the embodiment of the present invention includes:

[0109] Step S201, the target base station determines that the user equipment UE needs to be...

Abstract

A user equipment handover method and a base station, which relate to communication technologies. When a target base station determines that a UE needs to be handed over from a source base station to a target base station, and needs to perform handover between a unicast bearer and a multicast / multicast bearer, due to the data in the target bearer The progress of packet sending may be less than the progress of sending data packets in the original bearer, so the target base station receives data packets sent by the original bearer and the target bearer at the same time. When the progress of receiving the data packet is in the middle, the UE is switched to the target bearer, thereby improving the service continuity during the UE switching process.

Description

technical field [0001] The present invention relates to communication technology, in particular to a user equipment switching method and a base station. Background technique [0002] Now people's demand for mobile communication is no longer satisfied with telephone and message services. With the rapid development of the Internet (Internet), a large number of multimedia services have emerged, and some of the application services can be realized by multiple users receiving the same data at the same time, such as Video on demand, TV broadcasting, video conferencing, online education, interactive games, etc. [0003] Compared with general services, mobile multimedia services have the characteristics of large data volume, long duration and delay sensitivity. The current IP (Internet Protocol, Internet Protocol) multicast technology is not suitable for mobile networks, because mobile networks have specific network structures, functional entities and unique wireless interface bear...
