A method for registration-less paging includes establishing a mobile device identity for a mobile device in a wireless network, determining a time instance for the identified mobile device to listen to pages, and sending a page from the wireless network to the identified mobile device during the determined time instance. In one example, the method is for a network-initiated attach procedure and includes receiving a request to attach a mobile device in a wireless network, generating a paging message based on the request to attach the mobile device, sending a paging indicator to a mobile device based on the paging message during a time instance based on an agreed rule, and accepting an attach procedure from the mobile device based on the paging indicator.

Systems and methods are described that facilitate multiple registrations and flow based mobility in a wireless communication network. A flow routing component can be included in a mobile device, home agent/p-gateway, or a policy and charging rules function server that determines the manner in which to route one or more IP flows through a set of network access entry points. The flow routing component can determine the routing based on a set of policies and/or network data, such as quality of service requirements, bandwidth requirements, network congestion, currently active IP flows, and so forth.

Method and apparatus for PCC enhancement for flow based mobility

Quality of service information can be used to facilitate wireless communication. A network entity, such as a terminal, as well as a network can initialize an authorization to establish a link using quality of service information. Various features can be integrated with the use of quality of service information, such as having quality of service reservation before a call and supplying a permanent identity for use in correlation.

Quality of service information configuration

A communication system extends IETF Session Initiation Protocol (SIP) signaling used by IMS architecture. As a basic use case, initially a first (UE) (controller) is in a media session (e.g., audio, video and message session) with a remote UE. To transfer provider of one media component to a controllee UE, the controller UEsends a REFER message with a relevant body to trigger the media session operations to a Service Centralization and Continuity Application Server (SCC AS). The SCC AS is able to interpret the contents of the REFER message to perform the media session manipulation on one or multiple UEs (originating UE itself or other UEs). The innovation provides for a REFER message that convey what needs to be done in a separate SIP header carrying target dialog and media line number(s), in a SDP body that REFER carries, or XML body that will be in REFER.

Methods and apparatus providing intelligent interface selection for legacy and non-legacy applications. The method includes intercepting a networking function call from an application desiring radio access, selecting a radio from a plurality of candidate radios based on selection criteria, and binding the radio to the application. To facilitate flow mobility, the method includes allocating an ephemeral port to the radio, generating a flow binding rule based only on the ephemeral port, and signaling the flow binding rule to a home agent.

Certain aspects of the present disclosure propose methods for identifying machine to machine (M2M) devices and services. Each device may indicate its M2M functionality either for each of the services performed by the device or for all of its services to a core network. The core network may report the M2M functionality of the device to other nodes in the network that may be involved with the M2M functionality of the device.

Signaling identification of machine to machine devices and services

In a multimedia communication session with multiple media components, one or more media components can be transferred from one access network to another access network and yet maintain the continuity of the overall communication session. Each session is first identified and thereafter the media component intended to be transferred is also identified. The identities of the identified session and component are sent to one or more entities within the communication network for executing the media component transfer.

Methods and apparatus for compression of headers in broadcasting BCMCS services in a wireless communication system are described. Techniques used in BCMCS systems without feedback include sending static context information during BCMCS service initialization for use in a decompressor in a mobile station. Techniques used in BCMCS systems with feedback include receiving feedback from distributed mobile station decompressors and adjusting the broadcasting compressor in response to the feedback. Techniques that reduce the number of operating states in both the compressor and the decompressor are described. Techniques to classify flows so that a reduced number of contexts are used to compress/decompress session packet headers in a push-to-talk service are described.

An apparatus and method for providing mobility to IMS sessions comprising connecting to an APN through a 3GPP access; determining if a non-3GPP access is available; determining if the APN is specific to an IMS application being used or desired to be used, or if an IP header of an IMS application flow matches a configured pattern; and performing one of: a) triggering an IMS Session Continuity flow through the non-3GPP access for the IMS application based on one of the following: if the APN is specific to the IMS application or if the IP header of the IMS application flow matches the configured pattern; or b) triggering an IP mobility flow through the non-3GPP access for the IMS application or a non-IMS application if the APN is not specific to the IMS application and if the IP header of the IMS application flow does not match the configured pattern.

Bearer context maintained by an access terminal is synchronized with a network so that a change in the status of the bearer context may be reflected at the network. For example, if an access terminal determines that a resource previously requested by the access terminal is no longer needed, the access terminal may deactivate the bearer context locally in a case where the access terminal is unable to communicate with the network. In such a case, the access terminal may synchronize its bearer context with the network once the access terminal reestablishes communication with the network. For example, the access terminal may send a message to the network indicating that the access terminal has deactivated the bearer context.

Synchronizing bearer context

Methods and apparatuses are provided that facilitate handling failures in policy rule installation and/or related bearer modification procedures. A set of modified policy rules can be provided to a gateway for enforcement thereof and/or correlation with a bearer of a device. The gateway can attempt to install the modified rules and can utilize a credit control request (CCR)/credit control answer (CCA) exchange to notify of a status of the modified rule installation and/or related bearer modification. A policy charging and rules function (PCRF) can, thus, determine the status based on the CCR/CCA exchange. If the status indicates failure, the PCRF can revert to previous policy rules. In addition, an application function can be notified of the status.

Method and apparatus for handling policy and charging control rule or quality of service rule modification failures

Devices and methods are provided for handing off an access terminal from a macro base station to a femto access point (AP). In one embodiment, the method involves receiving a facilities directive or the like from a communication network entity, such as, for example, a serving mobile switching center (MSC). The method may involve selecting the femto AP based at least in part on femto configuration information, which may include at least one global identifier of the femto AP. The method may involve determining a uniform resource identifier of the femto AP based at least in part on at least one global identifier (e.g., MSC identifier and/or cell identifier).

Systems and methods for correlating multiple registrations from a single device are disclosed. A private ID used in an prior registration may be used to obtain subsequent private IDs. The subsequent private IDs may be used in subsequent registrations. An instance ID from an prior registration may be used in conjunction with different registration IDs in subsequent registrations.
