The invention proposes a method to support a handover of a service of a user equipment between a source eNB and a destination eNB in a wireless communication network with carrier aggregation, which includes the steps of: the destination eNB determining a primary component carrier jointly with the source eNB; transmitting a handover command to be transmitted to the user equipment to the source eNB, the handover command including indication information of the primary component carrier and dedicated preamble assignment information; the source eNB receiving the handover command to be transmitted to the user equipment from the destination eNB and forwarding the handover command to the user equipment; and then the user equipment accessing the destination eNB in response to the handover command. Also apparatuses performing the foregoing method in the source eNB, the destination eNB and the user equipment are proposed correspondingly. The technical solution of the invention improves the smoothness and efficiency of handing over a service of a user equipment between two eNBs in a carrier aggregation scenario and simplifies data transmission between the source eNB and the destination eNB in the handover procedure of the user equipment.

The present invention provides a method for handing over a terminal from a packet switching domain to a circuit switching domain during a non steady state of a call, a network element managing service centralization and continuity, an access device, a network element managing mobility of a terminal, as well as a communication system at least comprising at least a terminal, a network element managing service centralization and continuity, an access device and a network element managing mobility of a terminal. The method comprises a first network element anchoring the call based on the call setup request received from the terminal, and storing a provisional response returned to the terminal and the state of the call; the terminal detecting that a handover is necessary and sending a measurement report to an access network; the access network deciding to request a second network element for handover, upon detection of a signaling bearer while the measurement report meets handover condition; the second network element deciding to send the first network element a PS to CS handover request upon detection of the signaling bearer, after receiving a request for handover from the access network; and after reception of said handover request, if the first network element detects that the call is in the non steady state, than it checks the previously stored provisional response and sends the provisional response to a third network element, whereby completing the session handover procedure and updating the remote end.

In a method of configuring a cell for operation in a wireless communication network, a determinable neighborhood of cells within the network is used for cell configuration. In the method, a neighborhood of cells is selected for the given cell to be configured. Data is acquired from cells of the selected neighborhood, and configuration settings for the given cell are determined based on the acquired data.

A system, method and apparatus for vending network access by determining access pricing or tariffs for one or more of a plurality of network access regions using one or more of an eNB cell congestion level, an eNB congestion level, a quality of service level, an access technology, a level of activity by a target subscriber and the like. The access pricing is offered to potential access purchasers along with optional metadata indicative of, illustratively, user equipment and network parameters associated with the cell or eNB. The pricing may be offered via an API to allow automatic purchase decisions by access purchasers.

An arrangement is described for capturing and reporting call-through events in connection with phone numbers embedded in advertising impressions sent to mobile wireless devices. A call-through event is said to occur when a phone number embedded within an advertising impression is called from the mobile device. The system includes a call-through detector on the device that captures data related to a call-through event and communicates the captured data for one or more phone numbers over the network to a server. The server collects the captured data from various mobile devices and can correlate those with the advertisements sent to the mobile devices. A call detail information record sent from a device may contain detailed information about the context in which the call was made from the mobile device, including, for example, time of day or device location.

A method and system for authenticating a user to provide access to a secure application configured on a mobile device are disclosed. The method includes receiving an input from the user. The input is associated with a plurality of parameters. The method includes extracting a biometric pattern based on the input. The biometric pattern may be generated from the plurality of parameters associated with the input. The method may include comparing the biometric pattern with a plurality of reference patterns. The plurality of reference patterns are pre-defined by an owner of the mobile device. Furthermore, the method may include authenticating the user when the biometric pattern matches a reference pattern associated with the secure application from the plurality of reference patterns. Moreover, the method includes allowing the user to access the secure application, based on the authentication.

In one embodiment, the access node includes a vectoring control unit for estimating crosstalk coefficients between a set of subscriber lines based on crosstalk measurements carried out over the set of subscriber lines during a crosstalk measurement phase, and a vectoring processing unit for jointly processing, for crosstalk mitigation, signals to be transmitted over, or received from, the set of subscriber lines based on the estimated crosstalk coefficients. The access node further includes a controller configured to either postpone the execution of power adaptation over a particular line out of the set of subscriber lines after the completion of the crosstalk measurement phase, or to postpone the crosstalk measurement phase after the completion of power adaptation over the particular line.

In one embodiment, a first network device is configured to receive from a second network device a site-type attribute of the second network device, and to control establishment of a tunnel between the first network device and the second network device based at least in part on the received site-type attribute. The site-type attribute may be received in the first network device as part of a Border Gateway Protocol (BGP) message transmitted by the second network device to the first network device, and may comprise a Multicast Virtual Private Network (MVPN) site-type attribute indicating whether the second network device is a sender site of the MVPN. Controlling establishment of the tunnel between the first network device and the second network device may comprise preventing setup of the tunnel if the received site-type attribute indicates that the second network device is a sender site of the MVPN.

A controller in a video headend or other transmission element of a signal distribution system is operative to detect a condition in which unicast transmissions of a given content stream to a plurality of terminals meet a specified threshold. The controller starts a multicast transmission of the given content stream in response to the detected condition, and transitions at least one of the terminals to the multicast transmission. In one embodiment, the controller identifies at least one of the terminals as a terminal that will receive the multicast transmission of the given content stream in place of its unicast transmission prior to one or more of the other terminals receiving the multicast transmission. The controller stops the unicast transmission to the identified terminal if that unicast transmission has already been started, starts the multicast transmission, switches the identified terminal to the multicast transmission, and subsequently transitions one or more of the other terminals to the multicast transmission. The identified terminal may be a leading terminal or a trailing terminal.

A capability for secure communication of data from a source device to a destination device is presented. The source device has a device identifier associated therewith. The source device stores an encrypted version of the device identifier that is encrypted based on a master key of the destination device. The source device stores an encryption key. The source device communicates data to the destination device in a secure manner by encrypting the data using the encryption key and propagating the encrypted version of the device identifier and the encrypted data to the destination device. The destination device recovers the data sent by the source device by decrypting the encrypted version of the device identifier based on the master key to determine the device identifier, determining a decryption key based on the device identifier, and decrypting the encrypted data based on the decryption key to recover the data sent by the source device.
