Abstract
A mobile network platform creates a device group according to a member device supporting a mobile network multicast communication manner in a Machine-to-Machine Communications (M2M) group, generates an identifier of an external group corresponding to the device group, and requests a service capability exposure function (SCEF) to create the external group according to the identifier of the external group and an external device identifier of the member device supporting the mobile network multicast communication manner. When receiving an access request for the M2M group, the mobile network platform obtains the device group in the M2M group, learns of the corresponding external group, and then requests the SCEF to access the member device in the external group in a multicast communication manner. Hence, an amount of information generated due to interaction between an M2M platform and an M2M device is reduced, while reducing resource overheads.
