Locking structure includes a first connector, a second connector, a locking member, a sliding member, and a holding member. The first connector includes a first cavity and a first protrusion in the first cavity. The second connector includes a second cavity and a second protrusion in the second cavity. The locking member is slidably received in the second cavity and extends into the first cavity. A peripheral wall of the locking member defines a fastening groove. The sliding member extends into the second cavity and abuts the locking member to drive the locking member to move toward the first protrusion and the second protrusion so that two opposite side walls of the fastening groove press against opposite sides of the first protrusion and the second protrusion. The sliding member defines a latching slot. The holding member includes a latching member for latching in or disengaging from the latching slot.

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.

A resource acquiring method relates to the field of machine-to-machine communications (M2M) technologies, where the method is used by a consumer application to acquire a producer data resource generated by a producer application, and includes receiving a request message that is used to acquire the producer data resource and that is sent by the consumer application, where the request message carries indication information that is used to instruct to update the producer data resource and return an updated producer data resource, acquiring current moment data from the producer application, updating the producer data resource using the current moment data, and returning the updated producer data resource to the consumer application. Hence, a problem of mismatching between data generated by the producer application and data used by the consumer application is resolved.

Resource acquiring method and apparatus

A semantic validation method, applied to a Machine-to-Machine Communications (M2M) system, where the method includes receiving, by an apparatus storing a semantic description resource, an operation request related to a first semantic description resource, including semantic information of the first semantic description resource, an association relationship between the first semantic description resource and another semantic description resource, and a uniform resource identifier (URI) of an ontology referenced by the first semantic description resource, determining that the first semantic description resource is associated with the semantic description resource, sending a semantic validation request message to an apparatus that stores the ontology referenced by the first semantic description resource. Hence, accuracy of a resource and data shared between industries and applications using a public capability of the M2M system can be ensured in a case of no priori knowledge.

Semantic validation method and apparatus

A resource obtaining method, apparatus, and system, wherein the method includes: when a first edge node receives a first resource obtaining request sent by a second edge node, and a first target resource is not locally cached, the first edge node may determine, using shared popularity information of the first target resource, whether the first target resource needs to be cached. The shared popularity information of the first target resource is determined by a quantity of obtaining requests for the first target resource that are received by the first edge node from the first edge node and another edge node. Therefore, it is determined, using the shared popularity information, whether the first target resource needs to be cached.
