US Classification:

709205, 709202, 717171, 719317

Abstract:

Service applications at one or more service providers are bundled through a server thereby creating new services. The server comprises service agents, each of which corresponds to one or more service applications and proxies for its application(s) to perform service bundling. When a subscriber interacts with a service application and affects service specific data, the application sends this data along with the subscriber's intent with respect to this data to the server. The server next identifies a primary service agent, which is the agent proxying for the application. This agent determines a peer group of service agents, wherein each peer agent corresponds to a service application that together define a bundled service. The principal and peer agents subsequently negotiate/coordinate with respect to the service data. As a result, the agents may communicate with their respective service applications to determine a subscriber's current service data configurations and/or to update these configurations.

H04Q 7/20

US Classification:

370338

Abstract:

A system and method for mobility support of a mobile node having a home network in a heterogeneous roaming environment is presented. The method comprises the steps of authenticating the mobile node in a visited network and obtaining an address for the mobile node in the visited network, establishing a security connection between a functional component in the visited network and an agent in the home network, creating a home address for the mobile node, and using the home address to generate a SIP signaling address, a SIP media address, and a non-SIP media address, such that SIP non-media is transmitted using the security connection to the SIP signaling address, SIP media is transmitted using the security connection to the SIP media address, and non-SIP media is transmitted using the security connection to the non-SIP media address.

International Classification:

G06F 15/16

US Classification:

709228

Abstract:

A method and system for setting up and maintaining an IMS session. The method comprising transmitting an invite message from a registered user equipment, forwarding the invite message to a selected SIP proxy (P-CSCF), forwarding the invite message to a specified SIP server (S-CSCF) and relaying said invite message to a destination. The invite message contains a header and a payload. The header includes an identifier for the load balancing node. The load balancing node is assigned to the user equipment. There are at least two load balancing node, a primary and a secondary load balancing node. The identifier for the load balancing node does not change even if there is a failure of one of a primary load balancing node, the P-CSCFs or S-CSCFs. During registration, the routing information for the load balancing node is added into both via and record-route headers in a SIP registration request.

International Classification:

G06F 15/173

US Classification:

709223

Abstract:

A virtualized telecom system and a method for managing service continuity and mobility in a virtualized telecom system. The system comprises a plurality of execution nodes each configured to execute a network function by registering; and a manager node for registering each of the plurality of execution nodes, assigning a node identifier (Node ID) to each of the plurality of execution nodes, periodically polling each of the plurality of execution nodes for a status, and issuing control instructions to each of the plurality of execution nodes based upon the status of a respective execution node. Each of the plurality of execution node responds to the polling by transmitting its status to the manager node. The status includes runtime information and pre-configuration information.

US Classification:

709204

Abstract:

An inventive system and method for group communication among devices in M2M networks comprises associating one or more of the devices with a gateway having a unique identifier, initiating registration of the devices at an M2M network using the unique identifier of the gateway, providing from the network a temporary identifier to the gateway and associating, in the network, the temporary identifier with the gateway, attaching the devices to the network using the temporary identifier, and communicating information between the network and the device through the gateway. In one aspect, the devices can be classified into sub-groups and each sub-group has a sub-group head that can be attached to the gateway so that the devices can communicate with the network through the sub-group head instead of the gateway. Each sub-group can be associated with a unique temporary identifier, in addition to the temporary identifier associated with the gateway.

International Classification:

US Classification:

370328

Abstract:

A method for automatically provisioning a WiFi-equipped machine-to-machine (M2M) device is disclosed. A WiFi M2M gateway identifies a WiFi network identifier broadcast by a powered-on M2M device in WiFi ad hoc mode through a scanning procedure and joins the ad hoc network defined by the M2M device. The WiFi M2M gateway obtains device information (e.g., MAC address) of the M2M device. The WiFi M2M gateway transmits a command to the M2M device to switch from ad hoc mode to infrastructure mode. The WiFi M2M gateway registers the M2M device with an M2M server associated with a service provider based on the device information of the M2M device. The WiFi M2M gateway receives a fully qualified domain name (FQDN) associated with the M2M device from the M2M server.
