A user equipment, radio control node, method and computer program are disclosed. The user equipment is configured to communicate with other devices across a wireless communication network comprising a plurality of radio coverage cells, the user equipment being configured to respond to receipt of a message from the network, the message comprising a wait time, to not transmit a connection request until after expiry of the wait time; wherein the user equipment is configured during the wait time to receive paging requests from the network; and is configured to respond to at least some of the paging requests, the user equipment being configured to select the at least some of the paging requests to respond to in dependence upon paging information received from the network.

Responding to paging requests while waiting to request a connection to a wireless network

A method of controlling communication between a first network node and a second network node in a multi-carrier wireless communications system, network nodes and a computer program product are disclosed. The method of controlling communication between a first network node and a second network node in a multicarrier wireless communications system in which a predetermined set of a plurality of carriers are utilized to support communication between the first network node and the second network node, the predetermined set of the plurality of carriers comprising a primary carrier and at least one secondary carrier, comprises the steps of: determining an occurrence of an event requiring a change in the primary carrier; indicating to a third network node that a physical layer instruction is to be transmitted between said first network node and the second network node; and transmitting a physical layer instruction between the first network node and the second network node, the physical layer instruction encoding reselection information to cause the second network node to select a different carrier from the plurality of carriers as a new primary carrier. By sending the instruction using the layer one or physical layer, the speed at which the instruction can be transmitted between the network nodes is vastly increased, which enables fast switching to occur, thereby preventing a loss of communications between the network nodes. By indicating to a third network node that a physical layer instruction is to be transmitted between the first network node and the second network node, maintenance of synchronization is simplified and unpredictable network behavior is minimized.

Controlling communications in a multi-carrier wireless communication system

Wireless telecommunications network nodes, methods and computer program products are disclosed. A wireless telecommunications network node method, comprises determining a cause of a radio link failure which occurred when a user equipment is in proximity to an uplink-downlink imbalance region; and in response to the cause of the radio link failure, initiating action to optimize control of user equipment uplink-downlink decoupling-recoupling when in proximity to the uplink-downlink imbalance region. In this way, by establishing the cause of the radio link failure, it is possible to take action to alter the user equipment uplink-downlink decoupling-recoupling procedure in order to help prevent such radio link failures occurring in the future.

Wireless telecommunications network nodes and methods

A method is provided of authenticating a message from a femtocell base station in a wireless telecommunications network comprising a security gateway and a femto-gateway. The method comprising the steps of: checking by the security gateway that a source IP address in the message from the femtocell base station accords with that expected from that femtocell base station, and checking by the femto-gateway that the source IP address in the message accords with that expected from that femtocell base station by inspecting a database relating a femtocell base station identifier to source IP address data.

Wireless telecommunications network, and a method of authenticating a message

User equipment and method of notifying a wireless communication network of impending autonomous cell reselection from a serving cell to a second cell. The user equipment comprises: monitoring logic, determining logic and notification logic. The monitoring logic is operable to monitor signals received from said serving cell and said second cell; the determining logic is operable to determine whether the signals received from said serving cell and said second cell meet predetermined cell reselection warning criteria, and the notification logic is operable, if said predetermined cell reselection warning criteria are met, to notify said serving cell of said impending autonomous user equipment cell reselection to said second cell. Accordingly, user equipment is operable to send an indication of cell reselection to a network prior to fully triggering a cell reselection procedure, thereby allowing a network to make preparations for an impending cell reselection event, thereby minimizing potential disruption to a network user.

Autonomous cell reselection by a user equipment

A method is provided of deactivating PDP Context upon transfer of a connection with a user terminal between a femtocell base station and a macrocell base station, the method comprising: the femto base station receiving a message including a first identifier of a PDP Context, altering the identifier of a PDP Context to a second identifier, and forwarding the altered message to the core network, the core network receiving a message including an identifier determines that the received identifier does not match the identifier that it expects and so deactivates the PDP Context.

Deactivating packet data protocol context

A femtocell arrangement comprises a plurality of femtocells Femto 1 to Femto 13 having coverage distributed over a region, such as, for example, an office. A border femtocell, Femto 3 or Femto 10, of said plurality has coverage at an entrance to the region and is arranged to operate at a higher transmit power level to provide a larger coverage area than that provided by neighboring femtocells. In addition, the border femtocell may be allocated a specific Primary Scrambling Code (PSC) to show its designation as a border femtocell. An approaching user equipment UE 1 or UE 2 tends to attach to the higher transmit power border femtocells. The Femto Gateway managing the connection is aware of the likelihood that an approaching UE will tend to attach to a border femtocell, and this is further confirmed by the use of a specific PSC. Hence, handover is expedited as the most suitable femtocells may be chosen as targets for handover.
