  • Patent number: 8588208
    Abstract: A method performed by a wireless node includes receiving a data flow associated with user devices; performing a packet inspection of the data flow; determining whether a network address of the wireless node matches another network address associated with the data flow; converting the other network address to a layer 2 identifier when the other network address matches the network address; establishing a bearer link within the wireless node based on the layer 2 identifier; and offloading the data flow from layers of a network, which are higher relative to the wireless node, to the bearer link, wherein the data flow does not traverse the layers.

  • Publication number: 20130252584
    Abstract: A method and article of manufacture to reactivate a user identity card for a mobile station that communicates with a network is described. The user identity card is initially activated with the network. The user identity card has a unique identifier. Activation includes communicating with the mobile station from the network and programming the user identity card with network parameters. The network parameters programmed on the user identity card are then cleared after a preset period of time. The user identity card is reset to an unactivated state and then the user identity card can be reactivated with the network.

  • Patent number: 8533369
    Abstract: A smart card determines if the smart card has been inserted into a device, and retrieves a device identifier and at least one application configuration value from the device if the smart card has been inserted into the device. The smart card compares the retrieved device identifier and the at least one application configuration value with a device identifier and at least one application configuration value previously stored in the smart card. The smart card causes the retrieved device identifier and the at least one application configuration value to be sent to an Over The Air (OTA) server if the comparison indicates that the retrieved device identifier or the at least one application configuration value is different than the previously stored device identifier or the at least one application configuration value, so that the OTA server can supply application parameter changes to the mobile device for future device operation.

  • Patent number: 8515392
    Abstract: A method including receiving a network access request that includes an international mobile subscriber identity (IMSI) stored by a smart card associated with a user device; determining whether self-subscription to a service plan or reactivation of a suspended service plan is permitted based on self-activation data, wherein the self-activation data includes a mapping between IMSIs and data that indicates a granting or a denying of network access; selecting network access rights based on the self-activation data when it is determined that self-subscription to the service plan or reactivation of the suspended service plan is permitted; generating a temporary user profile based on the selected network access rights; and providing limited network access to the user device, wherein the limited network access permits a user to self-subscribe to the service plan or reactivate the suspended service plan.

  • Patent number: 8494522
    Abstract: Identification of radio coverage of a mobile station (MS) via a pico cell, such as an IP-BTS in a user premises (e.g. residence or business customer location), enables a mobile/wireless service provider to differentiate between coverage under a pico cell and coverage under a macro network. In a disclosed example, when the MS requests registration/authentication through a pico cell, a related signaling message includes a pico cell identifier (pID). A home location register (HLR) is provisioned with a pID, so that the HLR can decide to accept or reject the registration/authentication requests. For example, if the particular MS is provisioned for services from a specific pico cell, the HLR will grant the registration/authentication and allow the network to process calls for the mobile station through the identified pico cell. This enables the provider to allow discounted services through pico cell, e.g. as a replacement for a landline.

  • Publication number: 20130157700
    Abstract: A device receives, from an application server, a message destined for a user equipment, and reformats the message into a non-access stratum (NAS) transparent message. The device also provides, to a home subscriber server, a query for an identification of a mobility management entity serving the user equipment, and receives, from the home subscriber server, the identification of the mobility management entity serving the user equipment. The device further provides the NAS transparent message to the identified mobility management entity, where the mobility management entity forwards the NAS transparent message to the user equipment.

  • Patent number: 8340670
    Abstract: A fully qualified domain name may be used to identify a session initiation protocol server with which a client device may connect to IMS services in a network. In one implementation, a network device may receive a request to register a client device for IMS services. The network device may determine a fully qualified domain name corresponding to one or more SIP servers that process SIP signaling packets for the client device and transmit a message initiating resolution of the fully qualified domain name into a plurality of IP addresses.

  • Patent number: 8260258
    Abstract: Provisioning of target related information into an IP Multi-media Subsystem (IMS) communications network, to provide lawful intercept, utilizes an interface between a lawful intercept server (LIS) and one or more of the Home Subscriber Servers (HSSs) of the network. The LIS provisions an HSS with target information for LI, with respect to a subset of the overall list of LI targets, that is to say with respect to those of targets homed on the respective HSS. The HSS provisions the target list for its subset down to Call Session Control Function elements (CSCFs) logically attached to that HSS, to enable each CSCF to intercept signaling messages relating to communication for identified target user equipment (UE) devices. The intercepted signaling enables the LIS to identify a location of a target UE device in an access network and instruct a network control point to intercept content of communications for that UE device.
