  • Patent number: 7961714
    Abstract: A packet-based multimedia service is provided to a terminal in a network. A packet signaling connection is established between the terminal and the network. Signaling information for the multimedia service is transferred via the packet signaling connection using Session Initiation Protocol (SIP) or a similar protocol. A circuit bearer connection is also established with the terminal. Data for the multimedia service is transferred via the circuit bearer connection. This allows the data to be carried across networks which do not support the required QoS functionality for the packet-based service, or which cannot efficiently carry packet-based data. The circuit bearer connection can be established by a network entity or by the terminal. The circuit bearer can be interworked to a packet-switched bearer at some point in the network, such as at a gateway, so as to provide a remote party with the appearance that a fully packet-switched connection is being used.

  • Publication number: 20100260172
    Abstract: A method for providing a packet-based multimedia service to a mobile device in a network. The method includes initiating a multimedia session for the mobile device by establishing a packet connection between the mobile device and the network and establishing a circuit bearer connection between the mobile device and the network. The method further includes transferring information of a first type for the multimedia session via the packet connection. Additionally, the method includes transferring information of a second type for the multimedia session via the circuit bearer connection.

  • Patent number: 7746849
    Abstract: Provided is a method and system for providing a packet-based multimedia service to a mobile device in a network. The service is defined by a telecommunications standard, such as the 3GPP IP multimedia subsystem (IMS) standard, and the network does not support packet quality of service (QoS) functionality as required by the standard. A communications session embodying the method may be initiated by the mobile device or by the network. The method begins by establishing simultaneous packet signaling and circuit bearer connections with the mobile device. Signaling information for the multimedia service may then be transferred via the packet signaling connection using a session initiation protocol (SIP) or similar protocol. Data for the multimedia service may be transferred via the circuit bearer connection.

  • Publication number: 20100124911
    Abstract: To provide customized information to the user, a wireless communications network node receives a stream of data associated with a user. A first trend associated with at least a first attribute in the stream of data is identified, and based on the identified first trend, customized information is sent for presentation to the user at a mobile station.

  • Patent number: 7653189
    Abstract: A service tender node functions as an intermediary between subscribers and adjunct telecommunications services from multiple service providers to facilitate negotiation of services in real-time. The service tender node includes an index of services which is maintained and employed to search for applicable services in response to a tender request generated by a subscriber. Records in the index are described with an adaptive service definition which includes standard parameters and subjective parameters. The standard parameters identify types of service pursuant to telecommunications industry standards. The subjective parameters may be specified by individual service providers in order to differentiate their services within the service type defined by the standard parameters. Services generated from a search of the index pursuant to the standard parameters may be further sorted and filtered according to a comparison between a subscriber profile and the subjective parameters.

  • Publication number: 20060242310
    Abstract: The present invention provides a technique where application servers can initiate sessions within the IMS network by initially sending session initiation messages to the I-CSCF. By routing the session initiation messages to the I-CSCF, the application servers need not directly access the HSSs in order to initiate sessions. Upon receiving a session initiation message from an application server, the I-CSCF may access the HSS to identify an S-CSCF to use for session control and then route the session initiation message to that S-CSCF. The S-CSCF may then access the same or different HSS to determine how to further route the session initiation message to establish the session. The session initiation message may be routed toward other S-CSCFs en route to the appropriate user elements. The session may be a session established between user elements or between the application server and a user element.

  • Publication number: 20020087665
    Abstract: The present invention relates to a method and system for enabling resources to be defined, tracked, verified, resolved and managed both statically and dynamically. Resource management may be performed explicitly and consistently throughout a system, regardless of resource type. When a resource is defined, the resource may be assigned a unique specifier which may include a resource ID, type ID, version ID and/or other identifier. This information may be stored in a centralized repository, preventing redundant definitions of similar resources. Software or other applications may request (or require) access to a resource from a resource manager, regardless of resource type, retrieval mechanism or location.
