A device attestation server and method for attesting to the integrity of a mobile device is provided. An attestation request is sent from a mobile device to a device attestation server. The device attestation server runs an attestation method that is supported by the mobile device. The device attestation server creates an attestation token that includes a validation result and a plurality of attributes. The device attestation server sends the attestation token to the mobile device, which performs a validation method using the attestation token.

State machine diagram () illustrates inactive connection () management wherein all bindings are deregistered, but active sessions remain. The mobile station may, re-register the connection (), to stop the Linger Timer () and return the connection to the active state () before timeout, or otherwise before the inactive connection is terminated. Otherwise, the Linger Timer may be stopped when the last active session is moved to a different connection, or released (). If the Linger Timer times out (), any active sessions will be released without the explicit action of the mobile station. In the active state (), if all bindings are deregistered and no active sessions are present, the connection may be terminated immediately as in (), without invoking the Linger Timer. Thus, the mobile station has an opportunity to take action regarding remaining sessions, such as releasing or refreshing on a different but active connection.

A method of updating core domain information for use by a communication device () for routing a service for the communication device in a communication environment () including a core network () having a plurality of core domains (), and a plurality of radio access networks (), each of the plurality of radio access networks being associated with at least one of the plurality of core domains, comprises generating () by the core network network information. The network information includes information identifying a preferred core domain for the communication device and a preferred radio access network and being based on network based parameters provided by the core network and connectivity information received from the communication device identifying the radio access networks of the plurality of radio access networks which are available to the communication device for communication. The method further comprises receiving () at the communication device from the core network the network information and updating () the core domain information in the communication device based on the network information. The updated core domain information is used by the communication device for routing a service.

Multimedia IMS communications are established by matching callee capabilities with caller preferences and identifying a URI parameter in response thereto. When a session initiation protocol (SIP) request identifying caller preferences for an internet communication session and an identified callee is received (), a determination is made of whether the identified callee is a registered address of record (AOR) or not (). If the identified callee is a registered AOR (), a uniform resource identifier (URI) parameter and a globally routable user agent URI (GRUU) associated with callee capabilities are identified (). The URI parameter is used to create a modified SIP including the URI parameter () for sending () to an IMS enabled wireless communication device ().

A method for increasing performance of a wireless communication system is provided. The method includes determining () quality of service parameters that will result in a reduced likelihood that an application assigned the determined quality of service parameters will be scheduled for transmission, identifying () an application to be provided service that is less than best effort, and assigning () the determined one or more quality of service parameters to the identified application. In an embodiment, the method further assigns () a dedicated bearer to the identified application and either does not schedule () the dedicated bearer at all or schedules () the dedicated bearer less frequently compared to a frequency of scheduling a default bearer.

Active sessions and dialogs may be moved between connections and P-CSCFs. For example, in some embodiments either new bindings may be created with a different connection for a Public User ID or the UE may re-register one or more specific bindings for a Public User ID from one connection to another. The capabilities improve service continuity when handing over between IP-CANs. FIG.illustrates exemplary messaging for moving bindings to a new connection for a Private User ID between UE () and P-CSCF () when the UE () is in a visited IP-CAN, that is, visited network (). The UE () invokes the unprotected global seamless re-registration of the embodiments via an unprotected initial registration procedure wherein the UE () includes a 'seamless-ims' parameter in the Require and Proxy-Require headers of the REGISTER request (). The S-CSCF () provides the capability to subsequently re-register bindings over new or existing connections.

A method and device for transmitting at least one short messaging service message to at least one wireless device are disclosed. The method comprises receiving at least one short message service message request associated with a short message service message. The short message service message is destined for reception by a wireless device (). Prior to receiving the request, a short message service center () determines if a wireless device () is registered with a registrar () associated with a session initiation protocol network for communicating over a packet data network (). The short message service message is transmitted to the wireless device () through the session initiation protocol network communicating over the packet data network () in response to the request and with the determination that the wireless device () is registered with the registrar ().
