step 103: and closing the cluster user corresponding to the cluster ID monitored by the terminal currently.
Preferably, the determining whether the paging sent by the base station is detected includes:

if cluster users exist in the current cell, the base station periodically sends paging through an SC-MCCH channel, the content of the paging comprises cluster IDs of all the cluster users in the current cell, and if a certain cluster user is closed at the base station side, the cluster ID of the cluster user is deleted from the paging of the SC-MCCH channel.
When the terminal receives the SC-MCCH paging, the paging content is analyzed, whether the carried cluster ID changes or not is detected, if the cluster ID which is monitored cannot be detected in the current SC-MCCH period, the terminal immediately starts the operation of closing the cluster user, the air interface resource of the cluster user at the terminal side is released, and an application layer is informed to close the cluster user.
And the second method comprises the following steps: aiming at the scene that the current cell only has one cluster user:
if the current cell only has one cluster user, when the cluster user is closed by the base station side, the cluster air interface resource of the base station side is released, the base station side does not issue paging periodically any more, and at the moment, the terminal judges whether the cluster user is closed by detecting whether the PDCCH indication of the SC-MCCH is received, which specifically comprises the following steps:
if the PDCCH scrambled by a single-cell radio network temporary identifier (SC-RNTI) is not detected in the current SC-MCCH repetition period, adding 1 to N (the initial value N of a counter is 0), if the PDCCH scrambled by at least one SC-RNTI is received in the current SC-MCCH repetition period, clearing 0 to N, and when N is more than TH-MCCH, immediately starting the operation of closing the cluster user at the terminal side, releasing the air interface resources of the cluster user at the terminal side, and informing an application layer to close the cluster user. Wherein, the TH _ MCCH is a configurable threshold, and the preferable value range is 1-20.
