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.

Abstract: Embodiments of the present invention disclose a resource obtaining method and a related device, to effectively reduce redundant data transmission between a registrar and a resource server. The method in the embodiments of the present invention includes: receiving, by a registrar, a first request sent by a terminal for obtaining a target attribute included in a resource, where the first request carries a uniform resource identifier URI of the target attribute; determining, by the registrar based on the URI, that the registrar stores the resource to which the target attribute belongs, where the target attribute is partial content included in the resource; and sending, by the registrar to the terminal, a valid target attribute indicated by the URI. The embodiments of the present invention further provide a registrar and a resource server, effectively reducing redundant data transmission between the registrar and the resource server, and saving a network resource.

Abstract: The present application relates to the field of information technologies, and discloses an access point switching method and apparatus, to avoid interruption of another communication service that needs to be performed with an AE by using an M2M platform, thereby improving user experience. According to the present invention, after an access point for the AE is switched from the M2M platform to the M2M gateway, the AE can receive communication services corresponding to the M2M platform and the M2M gateway.
