Handover method and apparatus, and information transmitting method and apparatus

A handover method, applied to a second network device, comprising:

• receiving a handover request transmitted by a first network device, wherein the handover request carries Multicast Broadcast Service (MBS) session/bearer information, the MBS session information is used for indicating an MBS session, and the MBS bearer information is used for indicating an MBS bearer, wherein the MBS session/bearer information comprises Quality of Service (Qos) configuration information of the MBS session/bearer currently received by a terminal, wherein the Qos configuration information is used to indicate each QoS flow in a QoS flow list mapped to a Radio Bearer (RB) corresponding to a MBS service that the terminal is receiving currently, which includes one or more QoS flow identities, QoS parameters of QoS flow level, and MBS session identity information;
• and
• determining, using the QoS configuration information, whether to configure a bearer for the MBS session for the terminal that is consistent with a bearer configuration used by the first network device;
• returning a handover response to the first network device according to the handover request, wherein the handover response is used for indicating at least one of the following:
• MBS session/bearer information that can be accepted by the second network device, MBS session/bearer information that cannot be accepted by the second network device, terminal UE (User Equipment) scheduling configuration information of the second network device, or bearer configuration information of the second network device,
• wherein the MBS session/bearer information comprises at least one of the following:
• the MBS session/bearer information that a terminal is interested in, the MBS session/bearer information currently received by the terminal, or terminal capability information, and
• wherein the terminal capability information is used for indicating that:
• the terminal supports receiving a unicast service and an MBS session in the same time slot;
• or, the terminal does not support receiving the unicast service and the MBS session in the same time slot.
