摘要： A method and a system for providing small cell information to a user equipment in a heterogeneous network environment are provided. A user equipment sends a request to a network entity for providing availability of one or more small cells in its proximity. The network entity obtains location information associated with the user equipment and retrieves a small cell map displaying the one or more small cells from a map database. Then, the network entity determines whether the one or more small cells are in the proximity of the user equipment using the small cell map. Accordingly, the network entity provides a notification indicating availability of the one or more small cells to the user equipment. Moreover, the user equipment initiates a scan for the one or more small cells based on the received notification.

摘要： A method and apparatus for establishing communication between a plurality of communication devices and a communication network using a single subscription is provided. The method receives a first request from a second communication device to get a subscription identity and capabilities of subscription for accessing the communication network using subscription of the first communication device. The method then sends the first request to a Universal Subscriber Identity Module (USIM) associated with the first communication device. Thereafter, the method receives a response from the USIM including subscription identity, access protection keys and capabilities of the subscription. Then the method generates unique key for the second communication device based on the response received from the USIM. The method then sends the response along with the generated unique key to the second communication device to establish communication between the second communication device and the communication network using the subscription of first communication device.

摘要： Disclosed is a method and system of deriving new keys for accessing a new system. The method enables an optimized authentication procedure during handover form an existing system to a new system by using the existing system access keys. The user equipment that is accessing the new system receives a temporary ID during handover preparation which enables the user equipment to perform a fast re-authentication. The method uses existing system access keys to derive system access keys for the new network.

摘要： The present invention relates to the field of mobility in heterogeneous wireless networks. In particular, the invention proposes a system and method of providing User Equipment (UE) initiated and assisted backward handover in the heterogeneous wireless networks. Depending on certain criteria, the UE may decide that if it needs a handover from a serving network to a target network. The UE initiates the backward handover by sending handover request message to the target network through the serving network. The serving network checks for the capabilities of the UE and authorizes the backward handover. The target network prepares for the backward handover and informs the UE when the target network is ready. The UE then starts the handover procedure.
