A method improves mobility and service recovery for a user in a wireless communication network. Service information concerning the user is stored in a registrar. A subscription message is sent from a user terminal to the registrar. A header in the subscription message contains a unique indication. In response to the subscription message containing a unique indication in a header, the registrar returns a notification message to the user terminal. The payload of the notification message includes service information for the user to be used by the user terminal for communication services.

A system and method are described whereby an enhanced handoff scheme provides for monitoring of mobile device conditions and network conditions associated with a current access network attachment, as well as with a plurality of access networks on a preferred access network list, to proactively initiate a handoff operation, thereby preserving the QoS constraints necessary for seamless delivery of IP multimedia services. In an embodiment, each of the plurality of access networks is connected to an IMS core network, whereby a policy function receives quality of service constraints associated with the launched application from the mobile device and orders a list of preferred access networks accordingly. Preferably, the policy function selects an appropriate access gateway associated with a target access network based at least in part on the mobile device conditions reported by the mobile device and the access network conditions monitored by the policy function.

A method implemented by a network device residing in a service domain, wherein the network device comprises an information centric networking (ICN) transport layer and a service access layer (SAL) for handling context-aware service logistics and service mobility overlaid on the ICN transport layer, the method comprising receiving, in the ICN transport layer, a message comprising a service request that originates from a user equipment (UE), in the SAL, retrieving, from the service request, contextual information relevant to the UE or an access network connected to the UE, determining, based on the contextual information, one or more services needed to execute the service request, and determining one or more service identities (SIDs) each of which identifies one of the one or more services.

A system for managing service mobility using an extensible Markup Language (XML) electronic signature. A mobility interface stops and stores the operation of a service being currently performed. Before the service is moved, a service serializer serializes service state information and converts it into an XML form which is attachable to an electronic signature. An XML security manager creates an XML electronic signature for the Manifest file of the Java ARchive (JAR) file of a service bundle, attaches the serialized service state information to the XML electronic signature, and records it. A service installer transmits the signed JAR file to an Open Service Gateway initiative (OSGi) framework that has requested that the service be moved.

A system and method for exchanging components between platforms is described. As a user terminal changes location or preferences, the user terminal may be provided with a new platform that supports desired services. A method and system that relates to migrating one or more components that provide composite services from one communication platform to another is described. A user terminal may receive one or more composite services provided by two or more components existing on platform. As the user terminal switches from one platform to another, the platforms attempt to provide the same services to the user with little to no interruption. Various aspects relate to shifting one or more components from the first platform to the second platform to provide local support for the services desired by the user terminal.

Aspects of a method and system for service mobility via a femtocell infrastructure are provided. In this regard, a mobile cellular enabled communication device may detect a femtocell operable to deliver content for one or more services to the mobile cellular enabled communication device, where the one or more services may be provided via a set-top-box communicatively coupled to the femtocell. The mobile cellular enabled communication device may communicate a user profile to the femtocell, wherein information in the profile may be utilized by the set-top-box to authenticate and / or authorize access to the services by the mobile cellular enabled communication device and thus the mobile cellular enabled communication device may receive the content from the set-top-box based on the authentication and / or authorization. The content may comprise voice, video, data, text and / or still images. The mobile cellular enabled communication device may detect the femtocell by receiving one or broadcast messages from the femtocell.

The present invention provides a method for supporting mobility of selected IP traffic offload (SIPTO) by a server undertaking a control plane in a mobile communication network. The method can comprise the following steps: receiving a handover request message for a terminal receiving a SIPTO service by means of a source base station to a target base station; deciding whether to deactivate the SIPTO service; performing a process for disconnecting a public data network connection (PDN) for the SIPTO, based on the decision; and transmitting to the terminal via the source base station a message including information for reactivating the SIPTO after the handover, according to the decision.

A method for handling an ATTACH reject message with packet radio service mobility management reject cause number (#14 cause) at a user equipment (UE) is provided. The method includes receiving, at the UE, an ATTACH accept message for a network service on a public land mobile network (PLMN) from a first network entity, wherein the PLMN is in a “forbidden PLMNs for general packet radio service (GPRS) service” list, detecting, by the UE, that the UE's evolved universal terrestrial radio access (E-UTRA) capability is disabled, and enabling, by the UE, the UE's E-UTRA capability and removing the PLMN from the “forbidden PLMNs for GPRS service” list.

The present invention relates to a service mobility management method and system in a virtualized environment. The method includes: when the FN needs to be migrated, the first virtual machine notifies the service management node of the virtual machine migration event through the virtual machine manager; the service management node notifies the second The virtual machine manager to which a virtual machine belongs sends a cache instruction; after the virtual machine migration process is completed, the second virtual machine notifies the service management node of the virtual machine migration completion event through the virtual machine manager; the service management node sends a notification to the first virtual machine The virtual machine manager to which it belongs issues a data transfer instruction, and the virtual machine manager to which the second virtual machine itself belongs transfers the received cached data to the second virtual machine. The present invention enables the virtual machine manager to cache the business data involved in the virtual machine during the migration process of the virtual machine, and forwards the cached data to the migrated virtual machine manager after the migration is completed, thereby maintaining the continuity of the business session without interruption.

When service requirements require moving of services registered with an object request broker (ORB) at a source server, continuity of service to service requests from clients may be provided by queuing the service requests at the source server. A server context with the same GUID as a source server context may be established at a destination server. URLs for the moved services may be registered with a destination ORB which may then begin receiving service requests. The source server may then respond to the queued service requests with respective URLs for the services registered at the destination ORB. Endpoints at the clients may be updated with the new URLs prior to resending the service requests. The movement of the ORB to the destination server may thus be transparent to the client application.
