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:
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.
Abstract:
Embodiments of the present invention disclose a method for switching of a device, an M2M platform and a network system. The method includes: a machine-to-machine M2M platform receives a re-registration message including a position of a device in a network service capability layer NSCL resource tree before registration and a position of the device in the resource tree of the NSCL after registration; the M2M platform generates mapping relationship between the position of the device in the resource tree of the NSCL before registration and the position of the device in the resource tree of the NSCL after registration. By way of the present invention, the problem in the prior art can be solved in a manner of re-registration.
Abstract:
An encrypted communication method relating to communication technologies includes allocating a same encryption key for a first application and a terminal that is only bound to the first application. The method also includes transparently transmitting information communicated between the terminal and the first application when determining that the terminal communicates with the first application by using the same encryption key.
Abstract:
A network system includes a device management (DM) server and a Machine to Machine (M2M) gateway coupled to the DM server and to a plurality of sensor devices in a sensor network. The DM server is configured to send a DM command. The M2M gateway is configured to: after receiving the DM command, access a topology tree that includes first and second management object (MO) nodes, wherein the first MO node includes an identification and a type of the sensor network and the second MO node describes a characteristic of each of the plurality of sensor devices and a connection relationship of the plurality of sensor devices; according to address information within the DM command, locate at least one of the first and second MO nodes; retrieve information from the located at least one of the first and second MO nodes; and send the retrieved information to the DM server.
Abstract:
The present invention provides a method, a group server, and an apparatus for operating a group resource; a member resource operation request sent to a member device carries an operation request identifier, so that the member device that the member resource belongs to determines, according to the operation request identifier, whether operation request identifiers stored by the member device include the operation request identifier, and processes the member resource operation request according to a determination result. Therefore, repeated processing or cyclic processing of the member resource operation request may be avoided.
Abstract:
A method for remotely managing a sensor network topology includes: receiving a device management DM command sent by a device management server, where the DM command acts on a preconstructed management object MO node and the MO node includes a node configured to discover a sensor network topology, a node configured to describe a sensor network topology, or a node configured to modify a sensor network topology; and managing a sensor network according to the DM command, where the management includes discovering the sensor network topology, describing the sensor network topology, or modifying the sensor network topology. By adopting the present invention, remote topology management of a sensor network successive to an M2M gateway can be implemented and the complexity for implementing the management is reduced.
Abstract:
A method, device and system for authenticating gateway, node and server are provided in this invention. The node receives a message sent by a gateway, wherein the message comprises a number T3 shared by the gateway and a server, and a gateway identification. The node encrypts data with a key K1 shared by the node and the server, the data including T3, the gateway identification, and a random number T1 generated by the node, and then sends the encrypted data and a node identification to the server through the gateway. The node decrypts data encrypted by the server and forwarded by the gateway with the key, determines that the server is a valid server according to a T1-related number obtained by decryption, and establishes a security channel with the gateway according to a new key obtained through the decryption.
Abstract:
The method includes: receiving, by a first managed object device, a first transaction resource creation request that is sent by an application server and includes an identifier of a first to-be-operated resource, a first execution time, and a first to-be-executed operation; receiving, by a second managed object device, a second transaction resource creation request that is sent by the application server and includes an identifier of a second to-be-operated resource, a second execution time, and a second to-be-executed operation; successfully creating, by the first managed object device, a first transaction resource according to the first transaction resource creation request, and successfully creating, by the second managed device, a second transaction resource according to the second transaction resource creation request.
Abstract:
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.
