  • Patent number: 9854005
    Abstract: Methods and apparatus to provide data network services to a non-registering endpoint are disclosed herein. A disclosed method includes, transmitting, by executing an instruction with a processor, information identifying the non-registering endpoint and a first list identifying a plurality of proxy-call session control functions to a plurality of serving-call session control functions, the plurality of proxy-call session control functions being statically assigned to process calls to the non-registering endpoint when selected by any of the plurality of serving-call session control functions. In the disclosed example method, the non-registering endpoint is unable to register with any data network. The first list can be provided to the plurality of serving-call session control functions in response to an event.

  • Patent number: 9571528
    Abstract: Many of the current IMS standards and enriched services were originally designed for the individual subscribers that are serviced by the wireless network. However, the IMS standards do not fully address the problem of providing the IMS enriched services and features to business PBX customers or wholesale customers that do not directly register to the IMS network. The present invention discloses a method for providing IMS enriched services and features to business PBX customers or wholesale customers through the use of a static provisioning and registration method.

  • Patent number: 9462049
    Abstract: A method and apparatus for providing subscriber load distribution in networks are disclosed. For example, the method receives capacity data and user equipment (UE) resource consumption data from a plurality of devices that process call control signaling messages within the communication network. The method receives a first request from one of the plurality of devices to re-register one or more selected user equipment, and selects at least one available device from the plurality of devices. The method then re-registers the one or more selected user equipment on the at least one available device.

  • Patent number: 9415135
    Abstract: The present invention provides materials and methods that can serve as a prosthetic and/or, for tissue engineer applications, as a supporting matrix in the stabilization of the myocardium. For example, the present invention provides methods of stabilizing an injured or defective myocardial wall in a patient including forming a prosthetic in situ by injecting, at a pre-selected site in the myocardial wall of the patient, a polymer network including: a cross-linked polymer, the cross-linked polymer being a hydrogel; and a linear polymer, the polymer chains of which are entangled within the cross-linked polymer, wherein the linear polymer is not covalently bonded to the cross-linked polymer.

  • Patent number: 9379914
    Abstract: A method and system are adapted to provide telephony services to aggregate endpoints on an Internet Protocol Multimedia Subsystem (IMS) network. The method includes assigning one or multiple PUIDs for surrogate registration purposes during the provisioning of the aggregate endpoint, performing reliable surrogate registration on behalf of the aggregate endpoint, allowing multiple SBCs to perform surrogate registrations independently for the same aggregate endpoint to achieve reliability, and providing reliable connection from an IMS core to the aggregate endpoints via multiple S/BCs. The system includes one or more Session Border Controllers (S/BC), at least one set of Call/Session Control Functions (CSCF), and an HSS operatively coupled together.

  • Patent number: 8852512
    Abstract: A monitor for monitoring the concentration of oxygen in a fuel or in an ullage over a fuel comprises (i) a sensing element comprising a luminescent substance comprising a luminophore and a support in which the luminophore is covalently bound to the support, (ii) a light source arranged to irradiate the sensing element with light, and (iii) a photosensor arranged to detect light emitted from the luminescent substance. The luminescent substance may be, for example, a platinum porphyrin covalently bound to silica.

  • Patent number: 8792480
    Abstract: A method for providing multimedia services to subscriber user equipment (UE) within an IP multimedia subsystem network (IMS) may include configuring the IMS to enable a single UE to fork register and cooperate with multiple serving-call session control functions (S-CSCFs). After obtaining IP connectivity, the single UE signals to register with the IMS and the IMS determines whether the UE is configured to fork register with multiple S-CSCFs. If the UE is configured, the IMS determines which S-CSCFs are eligible for the UE registration and fork registers the UE to multiple S-CSCFs of the eligible S-CSCFs. Consequently, incoming and outgoing calls to/from the UE are routed by the IMS to any of the multiple registered S-CSCFs.

  • Patent number: 8547965
    Abstract: Example methods, apparatus and articles of manufacture to provide uniform resource identifier (URI) portability for communication networks are disclosed. A disclosed example method includes receiving a first communication session initiation message identifying a called party, identifying a URI associated with the called party, querying a global URI database based on the URI to identify a domain name associated with a service provider network based on the URI, and sending a second communication session initiation message including the URI to the service provider network via the domain name.

  • Patent number: 8533340
    Abstract: Systems and methods provide virtual CSCFs in an IMS system. The Virtual CSCFs may be virtual S-CSCFs or virtual P-CSCFs. A master virtual CSCF may be used to distribute subscriber data and initial filter criteria to the virtual CSCFs in a group. Thus one of multiple servers may be used for processing call sessions for the same subscriber, thereby avoiding overloading a particular CSCF in an IMS system.
