Description

Technical Field

[0001] The embodiments of the present invention relate to the field of communications, and in particular to a method, apparatus and network device for switching services. Background Technology

[0002] Before a target handover, such as an Xn handover, occurs, the source access network node can exchange capability information with neighboring base stations, or the source access network node may have configured the capability information of neighboring base stations. During an Xn handover, the source access network node decides whether to send first information related to multicast services based on the capability information of the target access network node. An Xn handover requires an Xn interface between the source and target access network nodes; without an Xn interface, it is impossible to exchange or configure capability information.
