A method for updating multimedia broadcast multicast control channel information, comprising: updating, by a network side, Multicast Control Channel, MCCH, information in a short MCCH modification period, when the MCCH information to be updated is related to a resource configuration change of Multimedia Broadcast Multicast Service, MBMS, traffic data, based on a priority of the MBMS traffic data for which the resource configuration is changed, if the priority is a high priority, selecting to update the MCCH information in a short MCCH modification period; if the priority is not a high priority, selecting to update the MCCH information in a normal MCCH modification period; wherein the high priority refers to that the updated MBMS service has a higher priority than the existing MBMS service on the MCCH; transmitting, by the network side, the updated MCCH information; wherein, the method characterized by further comprising: in the short MCCH modification period, except MBMS traffic data with a high priority, not allowing to change content of the MCCH, and only allowing to change the content of the MCCH in the normal MCCH modification period, which comprises one or more items of the following content: the data modulation and coding scheme of each Physical Multicast Channel, PMCH, only being able to be changed in the normal MCCH modification period; the Multimedia Broadcast Multicast over Single Frequency Network, MBSFN, subframe allocation pattern of an MBSFN area corresponding to the MCCH only being able to be changed in the normal MCCH modification period; except the last PMCH, an end subframe of each PMCH only being able to be changed in the normal MCCH modification period, and an end subframe of the last PMCH being able to be changed in a current short MCCH modification period; except the last PMCH, a number of MBSFN subframes occupied by each PMCH only being able to be changed in the normal MCCH modification period. updating, by a network side, Multicast Control Channel, MCCH, information in a short MCCH modification period, when the MCCH information to be updated is related to a resource configuration change of Multimedia Broadcast Multicast Service, MBMS, traffic data, based on a priority of the MBMS traffic data for which the resource configuration is changed, if the priority is a high priority, selecting to update the MCCH information in a short MCCH modification period; if the priority is not a high priority, selecting to update the MCCH information in a normal MCCH modification period; wherein the high priority refers to that the updated MBMS service has a higher priority than the existing MBMS service on the MCCH; transmitting, by the network side, the updated MCCH information; wherein, the method characterized by further comprising: in the short MCCH modification period, except MBMS traffic data with a high priority, not allowing to change content of the MCCH, and only allowing to change the content of the MCCH in the normal MCCH modification period, which comprises one or more items of the following content: the data modulation and coding scheme of each Physical Multicast Channel, PMCH, only being able to be changed in the normal MCCH modification period; the Multimedia Broadcast Multicast over Single Frequency Network, MBSFN, subframe allocation pattern of an MBSFN area corresponding to the MCCH only being able to be changed in the normal MCCH modification period; except the last PMCH, an end subframe of each PMCH only being able to be changed in the normal MCCH modification period, and an end subframe of the last PMCH being able to be changed in a current short MCCH modification period; except the last PMCH, a number of MBSFN subframes occupied by each PMCH only being able to be changed in the normal MCCH modification period. the data modulation and coding scheme of each Physical Multicast Channel, PMCH, only being able to be changed in the normal MCCH modification period; the Multimedia Broadcast Multicast over Single Frequency Network, MBSFN, subframe allocation pattern of an MBSFN area corresponding to the MCCH only being able to be changed in the normal MCCH modification period; except the last PMCH, an end subframe of each PMCH only being able to be changed in the normal MCCH modification period, and an end subframe of the last PMCH being able to be changed in a current short MCCH modification period; except the last PMCH, a number of MBSFN subframes occupied by each PMCH only being able to be changed in the normal MCCH modification period.
