A method for performing group management, comprising: pre-allocating (S102), by a Machine-to-Machine/Man, M2M, gateway, a terminal peripheral group identifier of a terminal peripheral group to a terminal peripheral configured into the terminal peripheral group by an M2M user, and setting, by the M2M gateway, an initial state of the terminal peripheral, wherein the terminal peripheral group identifier is used for identifying the terminal peripheral group to which the terminal peripheral belongs; acquiring (S104), by the M2M gateway, a terminal peripheral identifier of the terminal peripheral initiating a registering request, and determining, by the M2M gateway, the terminal peripheral group identifier pre-allocated to the terminal peripheral according to the terminal peripheral identifier; sending (S106), by the M2M gateway, the terminal peripheral identifier and the terminal peripheral group identifier to an M2M application through an M2M service platform, wherein the terminal peripheral identifier and the terminal peripheral group identifier are used for the M2M application to locally create or update group configuration information corresponding to the terminal peripheral group after the M2M application authenticates the terminal peripheral; receiving (S502), by the M2M gateway, a group service request message from the M2M application through the M2M service platform, wherein the group service request message carries the terminal peripheral group identifier to which the group service request message is to be distributed; and distributing (S504), by the M2M gateway, the group service request message to all terminal peripherals in the terminal peripheral group corresponding to the terminal peripheral group identifier after activating part or all of terminal peripherals in a standby state in the terminal peripheral group. pre-allocating (S102), by a Machine-to-Machine/Man, M2M, gateway, a terminal peripheral group identifier of a terminal peripheral group to a terminal peripheral configured into the terminal peripheral group by an M2M user, and setting, by the M2M gateway, an initial state of the terminal peripheral, wherein the terminal peripheral group identifier is used for identifying the terminal peripheral group to which the terminal peripheral belongs; acquiring (S104), by the M2M gateway, a terminal peripheral identifier of the terminal peripheral initiating a registering request, and determining, by the M2M gateway, the terminal peripheral group identifier pre-allocated to the terminal peripheral according to the terminal peripheral identifier; sending (S106), by the M2M gateway, the terminal peripheral identifier and the terminal peripheral group identifier to an M2M application through an M2M service platform, wherein the terminal peripheral identifier and the terminal peripheral group identifier are used for the M2M application to locally create or update group configuration information corresponding to the terminal peripheral group after the M2M application authenticates the terminal peripheral; receiving (S502), by the M2M gateway, a group service request message from the M2M application through the M2M service platform, wherein the group service request message carries the terminal peripheral group identifier to which the group service request message is to be distributed; and distributing (S504), by the M2M gateway, the group service request message to all terminal peripherals in the terminal peripheral group corresponding to the terminal peripheral group identifier after activating part or all of terminal peripherals in a standby state in the terminal peripheral group. <EOS>
