LTE cluster communication method, user equipment, and first network element equipment

A method for LTE trunking communication comprising:

• receiving, by a first network element device, area identifier information reported by a user equipment which is ready to receive trunked service data through a multimedia broadcast/multicast service (MBMS) bearer;
• selecting, by the first network element device, a trunked service bearing mode according to the area identifier information;
• and
• sending, by the first network element device, the trunked service data through the selected trunked service bearing mode;
• wherein the first network element device selecting the trunked service bearing mode according to the area identifier information comprises:
• the first network element device judging whether to use a unicast bearer according to the area identifier information, selecting the unicast bearer as the trunked service bearing mode if determining that there is no available MBMS bearer or establishable MBMS bearer, and selecting the MBMS bearer as the trunked service bearing mode if determining that there is an available MBMS bearer or establishable MBMS bearer, the method further comprising:
• determining that there is the available MBMS bearer if the user equipment is in an MBMS coverage area and a trunked service has not begun yet and determining that there is the establishable MBMS bearer if the user equipment is not in an MBMS coverage area, a trunked service has not begun yet, and a network is able to configure a cell at which the user equipment is located as a new MBMS single frequency network (MBSFN) area or enlarge the original MBSFN area containing the cell at which the user equipment is located.
