Abstract:
The present invention discloses a method, a device, and a system for network exit or de-registration of a femto base station. The network exit method includes: performing, a de-registration procedure with an access gateway; de-authenticating the femto base station through a security gateway and an authentication server; and tearing down a tunnel between the femto base station and the security gateway. The de-registration method includes: receiving, a de-register request message from an access gateway, where the de-register request message carries a first identifier of a neighboring base station or/and a second identifier of an access gateway other than the access gateway; directing a terminal currently served by the femto base station itself to hand over to the neighboring base station corresponding to the first identifier or/and registering with the other access gateway corresponding to the second identifier; and sending a de-register response message to the access gateway.
Abstract:
A method and an apparatus for negotiating a master station are disclosed. The method includes receiving from a master station a management frame that carries a master identity; obtaining a maximum time interval between receiving of the management frame and receiving of a next management frame from the master station; and determining, according to a preset policy, a local station itself as a new master station if no more management frame is received after the maximum time interval.
Abstract:
A notification method, an access point (AP), a station (STA), and a wireless system are disclosed. The notification method includes checking whether a power event occurs, and notifying the power event to an STA if the power event occurs. According to the present invention, the STA can learn about the power event, which helps the STA to decide on the subsequent action according to the power event.
Abstract:
A network handover method, a communications system, and relevant devices are provided, so as to implement handover between a Wireless Fidelity (WiFi) network and a Worldwide Interoperability for Microwave Access (WiMAX) network. The method specifically includes the following steps. A user terminal determines a target network access point (AP) and acquires a tunnel destination address. A signaling transmission tunnel between the user terminal and the target network AP is established through a current network according to the tunnel destination address. The user terminal executes a network access operation with the target network AP through the signaling transmission tunnel. The communications system and the relevant devices are further provided. Thus, the handover between the WiFi network and the WiMAX network can be implemented.
Abstract:
In a method for managing a Customer Premises Equipment (CPE), an Auto-Configuration Server (ACS) designates a first designated instance number for a first instance object. A message is then sent to the CPE. The message carries the first designated instance number for the first instance object and is adapted to notify the CPE to take the first designated instance number as an instance number for the first instance object.
Abstract:
A method, system and apparatus for converting media contents are disclosed. The method includes these steps: a media conversion apparatus receives a media conversion service request from a media application terminal, where the media conversion service request carries a media content ID and playing capability information of the media application terminal; the media conversion apparatus sends a media content transmission request carrying the media content ID to the content source device; and the media conversion apparatus receives a media content identified by the media content ID from the content source device, converts the received media content according to the playing capability information of the media application terminal, and sends the converted media content to the media application terminal.
Abstract:
A gateway system for implementing access to various media is provided in the invention, and the gateway system includes: a communication media access module, for establishing a communication link with the corresponding media access network; a Media Independent Handover Functions module, for seamless handover between accesses to various media; and a handover decision module, for selecting a target network for the seamless handover. The gateway system may also include an authentication module, for sharing the authentication information of the User Equipment. Two methods for implementing access to various media are further disclosed in the invention. By the provided gateway system and methods, the User Equipment can access various media via the gateway system, seamlessly hand over between accesses to various media and achieve the access to a service network using the shared authentication information.

Abstract:
A method for selecting a Femtocell gateway includes: selecting, according to service capability information of a Femtocell gateway in the current network, a target Femtocell gateway; and sending a message that carries identification information of the target Femtocell gateway to the Femtocell for the Femtocell to access, according to the identification information of the target Femtocell gateway, the target Femtocell gateway corresponding to the identification information of the target Femtocell gateway, or for the target Femtocell gateway to perform a pre-attachment operation for a terminal requesting for access to the network.
Abstract:
The present invention discloses a handover method and a handover device. An attachment point is handed over from a service station of a first access network to a handover server of the first access network before a UE hands over from the first access network to a second access network. The handover server of the first access network is interacted with through the tunnel to enter an idle mode of the first access network after completing network access in the second access network. Attachment to a destination station of the first access network is performed to quit the idle mode and re-access the first access network when the UE hands over back to the first access network.
