Abstract: Systems, methods, and apparatuses are provided for handling a legacy circuit switched communication. A method may include receiving a service request message at a network node on a packet switched network that does not support circuit switched fallback. The method may additionally include determining that the service request message includes a request for establishment of a communication requiring a circuit switched connection and having a user equipment connected to the packet switched network as an end point of the communication. The method may further include releasing the connection between the user equipment and the packet switched network in response to the determination. Corresponding systems and apparatuses are also provided.

Abstract: A wireless device is in a closed subscriber group CSG which was selected manually by the user. The wireless device receives an input from a user to initiate automatic PLMN selection in order to attempt to register with a PLMN. The wireless device uses a registered PLMN during the automatic PLMN selection initiated by the user.

Abstract: Embodiments provide a method, apparatus and computer program for operating a user equipment (UE). The method beings by determining that a valid authentication for the UE, generated with a radio network operating with a first radio access technology (RAT), is not a mutual authentication between the UE and the network operating with the first RAT. In response, the UE unilaterally takes action to prevent the valid authentication that is not a mutual authentication from being used to authenticate with a radio network operating with a second RAT that utilizes mutual authentication.

Abstract: A device and method arranged to control access to resources of a communication network by a User Equipment (UE). One embodiment includes an apparatus for a user equipment for use in controlling access to resources of a communication network, the apparatus including a processing system arranged to cause the apparatus to: monitor for a change in a state of association between a Closed Subscriber Group (CSG) cell and the user equipment, said CSG cell having a Public Land Mobile Network Identity (PLMN ID) and a CSG Identity (CSG ID) associated therewith; and in response to a said change, communicate data indicative of the change, of said CSG ID and of said PLMN ID, for receipt by a Universal Integrated Circuit Card (UICC) associated with the user equipment, whereby to enable the UICC to control access to resources of said CSG cell.

Abstract: An apparatus and method in which a User Equipment (UE) can register with a wireless network without requiring a packet data connection to be established. Embodiments are described in which a UE can indicate to a Mobility Management Entity that a packet data connection is not required to be established immediately. This can free resources when the UE knows that it will not need to transmit or receive data for some time, which is often the case for UE using Machine to Machine communication. In other embodiments, the MME can delay the establishment of a data connection for a UE if there are temporarily not enough resources to support it. In one embodiment, an apparatus for configuring a user equipment for transmission of data over a wireless network is provided.

Abstract: When at user equipment UE transitions between radio access technology cells, at the transition a timer for controlling when the UE is to send a periodic location registration is reset. This avoids the UE being implicitly detached when it is unable/blocked in the packet-switched PS domain from performing a RAU but would be able to perform a LU, particularly when the UE is in PS/CS modes 1 or 2. Five different embodiments are detailed: the LU timer T3212 is reset with a value of time remaining in a tracking area update TAU timer T3412; T3212 is reset with an initial value for T3212; the RAU timer T3312 is reset with a value of time remaining in the TAU timer T3412; and the T3212 or T3312 reset is conditional on a value of time remaining in a PS backoff timer T3346 exceeding the value of time remaining in the TAU T3412.

Abstract: A method is provided that includes causing transmission of a first mobility management (MM) message from a UE to a core network including packet-switched (PS) and circuit-switched (CS) domains. The method may include causing transmission of the first MM message to a PS-domain component, and receiving a rejection message from the PS-domain component in response thereto. The rejection message indicates congestion as a cause for rejection of the first MM message. In response to receipt of the rejection message, the method may include running a back-off timer. While the back-off timer is running in an instance in which the rejection message indicates that circuit-switched services are permitted, the method may include causing transmission of a second MM message from the UE to a CS-domain component. A corresponding apparatus and computer-readable storage medium are also provided.

Abstract: A method, apparatus and computer program product are provided to facilitate the combined registration in both the PS domain and the CS domain. In response to an initial request for a combined registration for a PS domain and a CS domain, a method may receive an indication that the registration for one of the domains is successful but that the registration for the other domain is unsuccessful. The method may prevent, in response to the indication that the registration for one domain is successful but that the registration for the other domain is unsuccessful, another request for the combined registration for the PS domain and the CS domain for a predetermined period of time following the initial request. A corresponding apparatus and computer program product are also provided.

Abstract: An apparatus and method for attaching a wireless device to a wireless network. The apparatus comprises a processor arranged to, responsive to receipt of a reject message from a network control apparatus, cause the wireless device to: transmit a first attach request to the network control apparatus using a first communication layer and an existing connection between the wireless device and the network control apparatus; and responsive to a notification of a failure of the first attach request originating from a second communication layer which is lower than the first communication layer, transmit a second attach request to the network control apparatus using the first communication layer and a new connection between the wireless device and the network control apparatus, wherein transmission of the second attach request is effected independently of a timer started on receipt of the notification of a failure.

Abstract: A system includes a local mobile network and user equipment, where the user equipment is configured to detect a local network identity of a local mobile network, determine whether a selected condition involving the local network identity is satisfied, and indicate whether a breakout connection is appropriate based on whether the selected condition is satisfied. The breakout connection is appropriate when the selected condition is unsatisfied. A non-breakout connection is appropriate regardless of whether the selected condition is satisfied or unsatisfied In some embodiments, the selected condition is satisfied when the local network identity corresponds to a network identity of a home public land mobile network or an equivalent home public land mobile network.
