Communication method and communications device

An access network device, comprising:

• a processor;
• and
• a computer readable storage medium storing programming for execution by the processor, the programming including instructions to:
• receive from a core network device, a first group identifier of a first terminal group and an identifier of a terminal comprised in the first terminal group;
• and
• send the first group identifier and a second group identifier of the first terminal group to the terminal comprised in the first terminal group;
• wherein the first group identifier and the second group identifier are used to indicate a paging occasion for the first terminal group, and a paging message for the first terminal group is transmitted on a first physical channel,
• wherein the paging occasion is a subframe that is in a paging frame and that carries a paging information, and the paging frame is a radio frame that carries the paging message, and
• wherein the paging occasion for the first terminal group is used to send the paging message for the first terminal group in multicast mode.

A communication method, comprising:

• receiving, by a terminal, a first group identifier and a second group identifier of a first terminal group that are sent by an access network device or a core network device, wherein the terminal is a terminal comprised in the first terminal group;
• wherein
• the first group identifier and the second group identifier are used to indicate a paging occasion for the first terminal group, and a paging message for the first terminal group is transmitted on a first physical channel, and
• wherein the paging occasion is a subframe that is in a paging frame and that carries a paging information, and the paging frame is a radio frame that carries the paging message, and
• wherein the paging occasion for the first terminal group is used to send the paging message for the first terminal group in multicast mode.
