Abstract: Under one aspect, a system generates dynamic call models within an IMS network, allowing different user entities (UEs) to have different service experiences. The IMS network includes application servers (ASs) and a serving call state control function (S-CSCF) that receives and then forwards UE service requests. The system includes storage media storing a service tree, which defines potential call models that map potential UE service requests onto ASs. At least two potential call models map a specified potential UE service request onto different ASs that can provide different service experiences. The system includes control logic for providing session control, which receives UE service requests from the S-CSCF, receives the service tree from the storage media, generates a call model for each UE based on potential call models defined by the service tree and on the requested service, and invokes a specified AS based on the generated call model.

Abstract: Methods of avoiding or minimizing cost of stateful connections between application servers (ASs) and S-CSCF nodes in an IMS network with multiple domains. S-CSCF service logic is provided and connected to a co-located AS. The IMS includes a network operator administration domain and an MVNO service domain, and the S-CSCF logic and AS are maintained in the same domain, e.g., the MVNO or network operator domain.

Abstract: Methods and systems for provisioning IMS networks with Virtual Service Organizations (VSOs) or Mobile Virtual Network Operators (MVNOs) that have distinct service logic, enabling VSOs and MVNOs to provide distinctive service experiences. Call models are provisioned so that different users can have distinct IMS service experiences. The IMS network includes a serving call state control function (S-CSCF) for providing user device session control. A database having selectable call model information associates IMS service codes with application servers (ASs) based on a user/group identity. S-CSCF logic receives a service request having a user identity, accesses the database, and instantiates a call model having filter codes that associate IMS service codes with ASs. The ASs have service logic to provide services for a corresponding IMS service code.

Abstract: A method of controlling and delivering media content from a media server (MS) to a media renderer (MR) utilizing a wide area IMS network for control. The method involves: provisioning a serving node in the IMS network with control point (CP) logic that includes logic to negotiate media content delivery with a least one of an MS and an MR; provisioning a user endpoint (UE) device of the IMS network with control point proxy (CPP) logic that includes logic to negotiate media content delivery and VCR controls to control media presentation; in response to a media content delivery request, invoking the CPP logic and the CP logic to cooperatively negotiate media content delivery between an MS and an MR that uses local wireless or land line connections when possible in order to minimize wide area bandwidth usage.

Abstract: Mediation systems and methods for hybrid networks including an IMS network. A system and method mediates an IMS network having a serving call state control function (S-CSCF) for providing session control for user endpoint (UE) devices with an alternative network to create a hybrid network. A service and corresponding service request code are defined to utilize at least a subset of capabilities provided by said alternative network. The S-CSCF is provisioned to identify and receive an alternative network service request message from a UE, including providing a call model having at least one filter code to associate said alternative network service code with at least one application server (AS) dedicated to serving alternative network service requests, said AS being responsive to service point triggers (SPTs). The AS is in communication with and capable of controlling delivery of at least a subset of services provided by said alternative network.

Abstract: Systems and methods for providing dynamic call models for users in an IMS network. A system and method provisions dynamic call models within an IMS network having a serving call state control function (S-CSCF) for providing session control for user endpoint (UE) devices. At least one user endpoint device (UE) with agent logic, expresses dynamic context of the UE in a message and sends said dynamic context message to a S-CSCF, wherein said dynamic context includes at least a subset of devices that could be used as UEs or associated devices, network connections that terminate or emanate from said devices that could be used as UEs or associated devices, and capabilities of said devices that could be used as UEs or associated devices.
