A server acquires a feature label vector of each seed user and forms a first number of clusters corresponding different information categories according to the feature label vectors of the seed users. The server calculates a central vector of each cluster according to the feature label vectors of the seed users in the cluster. The server acquires a feature weight vector corresponding to the information categories. The server acquires a feature label vector of each potential user. The server calculates first distances from the potential users to the central vector of the information categories according to the feature label vectors of the potential users, feature weight vectors and central vectors corresponding to the information categories. The server selects a second number of potential users corresponding to the shortest first distances from the first distances and sends them information that is matched with corresponding information categories of the target users.

Information pushing method, storage medium and server

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.

Group multicast method, group creation method, and mobile network platform

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.
