20110249669 | METHOD FOR SERVICE INTER-WORKING AND SESSION CHANNEL ESTABLISHMENT, INTER-WORKING SELECTION FUNCTION MODULE AND DEVICE - A method for service inter-working and session channel establishment, an Inter-working Selection Function (ISF) module and device are provided. The method for service inter-working includes: receiving content which is corresponding to at least two media types and is sent by a calling party; and sending, according to the media types of the content, the content to Inter-Working Function (IWF) modules each corresponding to one media type, so that the IWF modules send the received content to a called party. In one aspect, a Converged IP Message (CPM) service may have sessions with a plurality of non-CPM services, thereby improving user experience; in another aspect, when the calling party intends to change the media types between the calling party and the called party with which the calling party has processed the service inter-working, it can be achieved just by directly changing the media types without disconnecting the session with the called party in advance. | 10-13-2011 |
20130160140 | MACHINE-TO-MACHINE COMMUNICATIONS PRIVACY PROTECTION METHOD AND SYSTEM, MACHINE-TO-MACHINE COMMUNICATIONS SERVICE MANAGEMENT ENTITY, AND RELATED DEVICE - Embodiments of the present invention provide a machine-to-machine communications privacy protection method and system, a machine-to-machine communications service management entity, and a related device. The method includes: after receiving a location access message, determining, by a service management entity and according to locating information, an entity that performs privacy inspection; and triggering, by the service management entity, the entity that performs privacy inspection to perform privacy inspection. The M2M service management entity determines in advance the entity that performs privacy inspection and triggers the entity that performs privacy inspection to perform privacy inspection. Therefore, with the method provided in the present invention, message interaction on an mId interface is reduced, thereby reducing a message overhead. In this way, a network load is reduced, and especially for a wireless network with an air interface, benefit that reduction of a signaling overhead brings is greater. | 06-20-2013 |
20130179557 | METHOD AND MANAGEMENT APPARATUS FOR PERFORMING OPERATION ON DEVICE RESOURCE - A method for performing an operation on a device resource includes: receiving a first request, which is requests an operation on a device resource, where a destination address of the first request is a mapped address of the device resource on a management apparatus; determining, that the device resource is created on a device corresponding to the device resource; generating a second request for performing an operation on the device resource on the device; and transmitting the second request to the device. A management apparatus for performing an operation on a device resource is also provided. By using the present invention, the complexity for the network application to perform an operation on the device resource can be reduced, and the convenience for the network application to perform an operation on the device resource can be improved. Therefore, extensive application of M2M can further be promoted. | 07-11-2013 |
20130219064 | DEVICE MANAGEMENT METHOD, MIDDLEWARE, AND MACHINE-TO-MACHINE COMMUNICATIONS PLATFORM, DEVICE, AND SYSTEM - Example embodiments of the present invention disclose a device management method, middleware, computer-program products, system, and apparatuses. The method includes: a resource access request is received by using a resource access interface, where the resource access request includes: a URI that is used to indicate a storage location of an accessed management object MO data resource; according to pre-created mapping between the resource access request of the MO data resource and a DM command, the resource access request of the MO data resource is converted into corresponding DM command, and according to pre-created mapping between the MO data resource and MO information, the MO information corresponding to accessed MO data is determined; and the DM command is sent to a target device corresponding to the URI to manage the MO information corresponding to the accessed MO data, so that the M2M applications may access different M2M platforms to manage devices, implementing end-to-end device management and related service applications. | 08-22-2013 |
20130294285 | METHOD FOR REMOTELY MANAGING A SENSOR NETWORK TOPOLOGY AND GATEWAY - 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. | 11-07-2013 |
20130346504 | GROUP COMMUNICATION METHOD AND APPARATUS FOR GROUP COMMUNICATION - A group communication method is provided, including: receiving, from a network application, a group access request that requests access to a group, where the group access request includes a group identifier of the group; obtaining group member information of all group members in the group according to the group identifier; according to the group member information, determining members of a first group that are connected to a service function entity through a same gateway in the group; and sending, to the gateway, a first group member access request that requests access to the members of the first group. In addition, a service function entity for group communication and a gateway for group communication are provided. The present invention is capable of reducing signaling overhead during group communication and thereby improving group communication efficiency. | 12-26-2013 |
20140298037 | METHOD, APPARATUS, AND SYSTEM FOR SECURELY TRANSMITTING DATA - The present invention provides a method, an apparatus, and a system for securely transmitting data. A method for securely transmitting data is provided, where the method includes: sending, by a user terminal, a resource access request carrying a first authentication header field to a server, where the first authentication header field includes a user identifier and a server identifier; and receiving a request response returned by the server, where the request response includes a second authentication header field and a message body, where the second authentication header field carries a third integrity digest, and the third integrity digest is obtained by the server by performing, after receiving the resource access request, calculation by using a third message-digest algorithm further according to a user password and message content; so that M2M transmission based on the CoAP protocol can be performed securely and reliably. | 10-02-2014 |
20150098361 | APPARATUS AND SYSTEM FOR MANAGING A SENSOR NETWORK - 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.
