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.

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 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.

A method, a network system and an interworking function entity for processing the switch of communication service are provided. The method includes: receiving a first register request message sent from a source network by a user equipment, and completing the register of the user equipment to a service interworking function (IWF) of the user equipment; receiving a second register request message sent from the source network by the user equipment, and sending the second register request message to a source service mobility management entity(MME) of the user equipment, so as to complete the register of the user equipment to the source service MME; receiving a switch request message of the user equipment in the source network, and forwarding the switch request message to the source service MME, so as to make the source service MME to perform a switch process to switch the user equipment into a target network.

The invention provides an emergency service information obtaining method comprising the steps: user equipment (UE) transmits a message expressing attachment update to a service mobility management entity (MME); after receiving the message which expresses the attachment update and is transmitted by the UE, the service MME transmits the message expressing attachment update success or failure, whichcontains the emergency service information supported by an evolution packet system (EPS) network in which the service MME is positioned, to the UE; and after receiving the message expressing the attachment success or failure, the UE analyzes the emergency service information. The invention also provides the UE and the MME. The technical scheme supplied by the invention is convenient for the UE toobtain the emergency service information supported by the positioned EPS network in time and enables the UE to smoothly develop emergency services.
