摘要： A network accessing method includes selecting a group representative dynamically from each machine to machine (M2M) terminal group, wherein terminals in the M2M terminal group not selected as the group representative serve as group members. The method also includes requesting, by the group representative, network access from a base station, and serving, as a group member automatically after entering an idle state or entering another cell. This enables multiple M2M terminals to access a network at the same time while avoiding network access congestion.

摘要： A method for random access of Machine to Machine (M2M) terminals is applied to a plurality of M2M terminals. The method includes dividing the plurality of M2M terminals into at least one terminal group, and allocating an identifier for each terminal group. After receiving the paging broadcast signaling transmitted by the base station, an M2M terminal in a terminal group determines whether the terminal group identifier carried in the paging broadcast signaling is the identifier of the terminal group that includes the M2M terminal. If true, the M2M terminal starts a random access process. A base station transmits a paging broadcast signaling on the basis of a terminal group rather than issuing a paging broadcast signaling only to individual M2M terminals so that a plurality of M2M terminals can be randomly accessed smoothly and efficiently without causing network access congestion nor affecting the use of public network users.
