The method comprises: scanning a current channel to obtain a signal of the current channel; calculating the maximum frequency offset envelope mean of the signal in each time slice; determining whether the maximum frequency offset envelope mean is within a preset frequency offset requirement range; if each maximum frequency offset envelope mean calculated in a first duration is within the frequency offset requirement range, determining that the signal is valid, the first duration being longer than the time slice and shorter than a preset synchronization interval; if any maximum frequency offset envelope mean is not within the frequency offset requirement range, determining that the signal is invalid, and proceeding to scan the next channel. By measuring the maximum frequency offset envelope mean of a signal in each time slice, the present solution can determine whether the signal of a channel is valid by staying in the channel for at most a first duration, thereby shortening the time of staying in a channel to which an invalid signal belongs, and avoiding missing a valid signal.

Provided are a communication method, system and apparatus for broadcast multicast, which are used for reducing a communication delay. In the embodiments of the present invention, subframe resources are reserved in advance for the pre-establishment of a session, and time-frequency positions of the reserved subframe resources are broadcast. After receiving a session establishment message for a new broadcast multicast session that is sent by an MCE, a base station executes a session pre-establishment operation and a formal session multicast operation in parallel, wherein the session pre-establishment operation involves determining a subframe resource from among the reserved subframe resources and taking same as a temporary resource, informing a terminal of monitoring multicast data on the temporary resource, and issuing multicast data of a new session on a time-frequency position of the temporary resource. In this way, it can be ensured that when session establishment is initiated, the transmission of multicast data can be started, thereby greatly reducing a delay between the session establishment and the transmission of the multicast data. After receiving a time-frequency position of a formal session resource, a terminal switches to the time-frequency position of the formal session resource so as to receive the multicast data.

Disclosed in the present application are a service scheduling method and system for an enhanced broadcast multicast service. The method comprises: determining whether a session is actually issued in a cell; if the session is not actually issued in the cell, then configuring a corresponding invalid indication for the session in scheduling information of a multicast channel; and sending the scheduling information of the configured multicast channel to a terminal within the cell. By means of the method, a terminal can be indicated that a session transmitted by a base station is not actually issued in a cell, so that the terminal achieves a power saving effect.

Provided are a switching method, a terminal and a base station. A time point at which a terminal sends a switching time point to a base station is at least a first duration ahead of the switching time point. The first duration is the duration required by the base station to establish channel resources between the terminal and a target satellite, and the target satellite is the next satellite that covers the position where the terminal is located. Hence, after receiving the switching time point sent by the terminal, the base station has enough time to establish the channel resources between the terminal and the target satellite, such that it can be ensured that, after the terminal moves to a cell that is covered by the target satellite, the terminal can use the target satellite to perform communication, thereby keeping communication uninterrupted. Moreover, at the switching time point, the terminal and the base station execute switching simultaneously without notifying the other end from one end, thereby avoiding the delay of signaling transmission and a large amount of signaling interaction, and ensuring that the communication of the terminal is uninterrupted.
