- the USD includes the service start time (s tar tt ime ) of the user-selectable MBMS service, the service duration (durat ion ), and the MBMS service area.
- the user equipment obtains the MBMS service identifier and the MBMS frequency of the MBMS service that the user equipment is interested in from the USD, and then compares with the MBMS auxiliary information of the base station, where the MBMS auxiliary information includes the MBMS frequency supported by the base station.
- the user equipment when the MBMS service satisfies the three conditions that the user equipment is interested, the user equipment is capable of receiving the MBMS frequency of the MBMS service, and the MBMS frequency of the base station supporting the MBMS service, the user equipment may receive the MBMS service.

- the user equipment can Receive the MBMS service. That is, the MBMS frequency reported by the user equipment in the MBMS interest indication must be the MBMS frequency corresponding to the MBMS service that the user equipment is interested in, the MBMS frequency that the user equipment is capable of receiving, and the MBMS frequency included in the MBMS auxiliary information of the base station.
- the MBMS service (or the MBMS frequency that is subsequently expressed by the user equipment) that is of interest to the user equipment is an MBMA service customized for the user equipment, or an MBMS service that is set by the user and has a user receiving the desired MBMS service.
- the MBMA service customized by the user equipment may be an MBMS service that is reserved by the operator for the user equipment. For example, for Unicom's user equipment, China Unicom's MBMS service is the MBMS service that is of interest to the connected universal equipment, while the MBMS service of the telecommunications is not the MBMS service that is of interest to the Unicom user equipment.
- the MBMS service set by the user with the user receiving the desired MBMS service may be received by the user equipment according to the personal preference of the user.

- the MBMS frequency range that the user equipment can receive ie, the reception of the user equipment
- the MBMS frequency range that the user equipment can receive ie, the reception of the user equipment
- the capability will change, resulting in a corresponding change in the range of MBMS frequencies that the user equipment can select.
- the user equipment optional MBMS frequency range changes include: the increase or decrease of the number of MBMS frequencies supported by the base station in the MBMS auxiliary information, and the increase or decrease of the number of MBMS frequencies that the user equipment can receive.
- the MBMS frequency supported by the base station or the user equipment can receive
- the user equipment cannot receive the MBMS service carried on the newly added MBMS frequency.
- the base station When deleting certain MBMS frequencies supported by the base station (or the user equipment can receive), if the deleted MBMS frequency is included in the original MBMS interest indication, performing MBMS handover on the user equipment according to the original MBMS interest indication may result in an MBMS handover error (That is, the user equipment MBMS cannot be switched to the cell in which the deleted MBMS frequency is located, or the user equipment MBMS is switched to the unrelated cell according to the deleted MBMS frequency. Therefore, in the above five scenarios, the original MBMS interest indication is invalid, and the user equipment is required to re-report the MBMS interest indication.

- the base station When the user equipment receives the unicast service and the MBMS service, the base station preferentially switches the user equipment MBMS to the cell where the MBMS frequency is located to ensure that the user equipment preferentially receives the MBMS service.
- the base station in the embodiment of the present invention is a base station that supports the MBMS service.
