    Abstract: A method and apparatus are described for performing Internet Protocol (IP) Multimedia Subsystem (IMS) operation. A wireless transmit/receive unit (WTRU) registers an IMS service priority with an IMS network. The IMS service priority indicates the WTRU's priority in receiving IMS services. The WTRU may receive an IMS service from the IMS network based on the WTRU's IMS service priority. The IMS service priority may be indicated using a priority value and the WTRU may use Session Initiation Protocol (SIP) messaging to signal with the IMS network. The WTRU may register the service priority value using a q-value parameter in an SIP Contact field header. The WTRU may also register a public user identity with the IMS network and the public user identity may be shared with other IMS-capable WTRUs.

    Abstract translation: 描述了用于执行因特网协议（IP）多媒体子系统（IMS）操作的方法和装置。 无线发射/接收单元（WTRU）向IMS网络注册IMS服务优先级。 IMS服务优先级指示WTRU在接收IMS服务方面的优先级。 WTRU可以基于WTRU的IMS服务优先级从IMS网络接收IMS服务。 可以使用优先级值来指示IMS服务优先级，并且WTRU可以使用会话发起协议（SIP）消息来与IMS网络进行信令。 WTRU可以使用SIP Contact字段头中的q值参数注册服务优先级值。 WTRU还可以向IMS网络注册公共用户身份，并且公共用户身份可以与其他具有IMS功能的WTRU共享。

    Abstract: A method and apparatus for managing content storage subsystems in a communications network are disclosed. The communications network is equipped with a plurality of content storage subsystems. The content storage subsystems store local copies of content to facilitate the delivery and distribution of the content to wireless transmit/receive units, WTRUs. The network, which is equipped with a proxy server and an entry server, receives requests for content or general-purpose data referencing content and determines whether the content is stored in the storage subsystems. In addition, the network also performs content ingestion in order to store copies of the content in the storage subsystems and content modification in order to move content from one storage location to another to achieve optimal content storage and distribution.

    Abstract: Techniques for inter-user equipment (UE) transfer (IUT) are disclosed. An application server may receive an IUT request for transfer of a media session toward at least one initial UE such that the media session is to be played by at least two target UEs. The server may determine eligibility for IUT with group synchronization based on the request. The server may send a message to the initial UE that IUT with group synchronization is not allowed on a condition that IUT with group synchronization is not allowed. Further, the server may trigger inter-destination media synchronization (IDMS) for group synchronization of media sessions among the UEs on a condition that IUT with group synchronization is allowed. The media sessions may include a first media session and second media session. The media stream may be played by at least two UEs that are geographically separated after the transfer.

    Abstract: An application server receives a request for service from a wireless transmit/receive unit (WTRU) associated with a home network that includes a home subscriber server (HSS) and a bootstrapping server function (BSF) coupled via a Zh reference point. The application server authenticates the WTRU at least in part by (i) redirecting the WTRU to an identity provider co-located with a network application function (IDP/NAF) and coupled to the BSF via a Zn reference point and (ii) receiving an assertion from the WTRU that the IDP/NAF has authenticated the WTRU based on user security settings retrieved from the BSF by the IDP/NAF over the Zn reference point. After authenticating the WTRU, the application server (i) retrieves user-specific Sh-reference-point-type data from the HSS via the IDP/NAF over the Zn and Zh reference points and (ii) provides the service to the WTRU based on the retrieved user-specific Sh-reference-point-type data.

    Abstract: A method and apparatus are described for synchronizing mobile station (i.e., wireless transmit/receive unit (WTRU)) media flows during a collaboration session. Inter-WTRU transfer request messages, flow addition request messages and session update request messages may be exchanged between a plurality of WTRUs and a session continuity control application server (SCC-AS). Each of the messages may include a session description protocol (SDP) attribute line containing time synchronization information (e.g., a presentation time offset (PTO) information element (IE), a media flow group identity (ID) and a synchronization tolerance IE). The SCC-AS may update the time synchronization information and include the updated information in messages it sends to the WTRUs, which may re-synchronize their respective media flows based on the updated time synchronization information.

    Abstract translation: 描述了在协作会话期间同步移动台（即，无线发射/接收单元（WTRU））媒体流的方法和装置。 可以在多个WTRU和会话连续性控制应用服务器（SCC-AS）之间交换WTRU间传输请求消息，流添加请求消息和会话更新请求消息。 每个消息可以包括包含时间同步信息（例如，呈现时间偏移（PTO）信息元素（IE）），媒体流组标识（ID）和同步容限IE）的会话描述协议（SDP）属性行。 SCC-AS可以更新时间同步信息，并将更新的信息包括在其发送到WTRU的消息中，其可以基于更新的时间同步信息重新同步其各自的媒体流。

    Abstract: A method and apparatus for interworking between a mobile network operator and an application provider are disclosed. A network application function (NAF) may be co-located with an OpenID provider such that an application server may communicate with the NAF to access a home subscriber server (HSS) via a bootstrapping server function (BSF). The interfaces between BSF and HSS, and between BSF and NAF may be enhanced to carry information that is available through Sh interface between the application server and the HSS. When the WTRU is roaming in a visited network, the application server may communicate with the visited network for charging and policing for serving the service request from the WTRU. The application server may be co-located with an NAF, and may authenticate the WTRU using Generic Bootstrapping Architecture, and may communicate with a BSF in a home network via an eZn-proxy function to access an HSS.
