  • System and method for integrating an outgoing cellular call as an enterprise call
    Patent number: 8688084
    Abstract: A method on a wireless user equipment (UE) device facilitates integration of an outgoing cellular call as an enterprise call. The UE device attaches to a wide area cellular network on which the device has a non-enterprise address. Upon blocking incoming calls, the UE device sends a request to a node in a data network to initiate an outgoing cellular call with an expectation of receiving an incoming circuit-switched (CS) call back from the network node within a time window. The incoming CS call contains an enterprise address associated with a user of the wireless UE device as a calling line identity to identify that the incoming CS call is related to the request to initiate the outgoing cellular call. The UE device indicates to the network node that a call leg is established between the enterprise user and the network node.

  • Systems and methods for achieving PLMN continuity when moving between networks of different types through network selection
    Patent number: 8626683
    Abstract: Systems and methods for achieving PLMN continuity when moving between networks of different types through network selection are provided. When a mobile station moves from a first network type, such as cellular, to a second network type, such as GAN, if there is a PLMN discontinuity, this may result in a dropped call. In order to avoid this, networks for the first network type and the second network type are selected such that there is PLMN continuity. This can involve reselection of a different cellular network than one currently providing service to the mobile station.

  • System and method for effectuating a SIP call in a network environment including IMS
    Patent number: 8599838
    Abstract: In one embodiment, a scheme is disclosed for effectuating a call in a network environment including a circuit-switched (CS) network and an IP multimedia subsystem (IMS) network. Call information associated with a call is sent from a user equipment (UE) device to an application server (AS) node disposed in the IMS network. The call information includes at least one of a call reference number and a called party's URI. When a message is received at the UE device from the AS node, which message includes the call reference number and an IP multimedia routing number (IMRN), the returned call reference number is verified that it remains valid based on a local timer mechanism associated with the UE device. The IMRN is then sent to the application server in order to facilitate a session with respect to the called party.

  • System and method for managing call continuity in IMS network environment
    Patent number: 8542678
    Abstract: In one embodiment, a scheme is disclosed for managing call continuity in a network environment including a circuit-switched (CS) network and an IP multimedia subsystem (IMS) network wherein unique identity (ID) information supplied by a user equipment (UE) device is utilized. A pool of dynamically allocable IP multimedia routing numbers (IMRNs) maintained at an IMS network node are used for associating an IMRN with call information received from the UE device, which can include at least one of a GRUU, Instance ID, and the called party number relating to a call. When the dynamically allocated IMRN is returned by the UE device, the network node utilizes the IMRN mapping to effectuate call continuity with respect to the called party.
