A method is provided for reclaiming bandwidth from an edge device. The method includes communicating a bandwidth query message to at least one session manager. The bandwidth query message specifies an amount of bandwidth that needs to be reclaimed from a single one of a plurality of edge devices in order to establish at least one additional session that delivers a digital service to a subscriber in a service group serviced by the plurality of edge devices over an access network. In response to communication of the bandwidth query message, a bandwidth query response message is received from the session manager identifying an edge device from which at least the specified amount of bandwidth can be reclaimed. A response is communicated to the session manager requesting the session manager to reclaim the specified amount of bandwidth from the edge device that has been identified.

The embodiment of the invention relates to a non-3GPP access network roaming attachment method, which comprises the steps of receiving a non-3GPP access network roaming attachment request; creating mobility management context and bearer management context; creating a GTP transmission tunnel between a home location data gateway and a first roaming location service gateway and an IP transmission path between a terminal and the first roaming location service gateway; and binding the GTP transmission tunnel and the IP transmission path. The embodiment of the invention also relates to a non-3GPP access network roaming attachment system, a network roaming quit method and a system thereof, and a roaming system. By using the embodiment of the invention, the non-3GPP access network can use the GTP-based roaming interface to realize roaming attachment and network roaming quit, so as to simplify the switch between the 3GPP access technology and the non-3GPP access technology, reduce investment cost of operators, and accelerate the implementation of non-3GPP access network application in the current network.

The invention provides a network resource optimizing method and a corresponding device which are applied to access equipment providing wireless access services to wireless terminal STA. The method and the device are characterized in that the method includes the following steps: step A, monitoring data flow of an online STA already accessed to a network, recording time duration when the online STA has no data flow, and adding the STA serving as an idle STA into an idle STA list when the time duration reaches a first preset threshold value; step B, judging whether enough online resources existing in a current network can be distributed to a new STA or not when the new STA requests for access to the network, if yes, allowing the new STA to be online, if not, selecting an idle STA from the idle STA list, enabling the idle STA to be offline to release online resources occupied by the idle STA, and then allowing the new STA to be online. By the method and the device, the defect of idle detection can be overcome, and a powerful guarantee is provided to network resource optimization.

The invention relates to an aggregation network with centralized control. An access network is described in which a centralized controller provides seamless end-to-end service from a core-facing edge of a service provider network through aggregation and access infrastructure out to access nodes located proximate to the subscriber devices. The controller operates to provide a central configuration point for configuring aggregation nodes (AGs) of a network of the service provider so as to provide transport services to transport traffic between access nodes (AXs) and edge routers on opposite borders of the network.

A method for providing network access privacy by classifying filter parameters of a group of users who are accessing one or more network destinations. The system includes a means for collecting information from both users, and about network destinations, generating suggestions for a user regarding filter parameters, and filtering network communications of users going to network destinations. In operation, users who are accessing network destinations are prompted to choose from a selection of filter parameters. The information provided by these users is then analyzed and used to generate suggested filter parameters for other users. As users provide more information to the system about various network destinations the system is able to provide more information to users about more network destinations and thus generate more accurate filter parameter suggestions. After a user selects their filter parameters the system filters a range of information coming from the user and going out to the network destination.

Multiple embodiments of the invention provide an authentication method and device for an application client of terminal equipment. Access network equipment in different regions configures IP addresses of different authentication servers, and receives a http access network message sent by the terminal equipment via the APP client; the access network equipment judges whether the APP client has been authenticated; if the APP client has been authenticated, the access network equipment forwards data sent by the terminal equipment via the APP client to a network server corresponding to the http access network message; and if the APP client has not been authenticated, the access network equipment redirects the http access network message of the APP client to the configured IP address of the authentication server, and sends the redirected http message to the terminal equipment. The method and the device can solve the problem that the address of the APP server is difficult to change in the APP client in the existing solution, so that the APP client can learn in which APP server address the authentication is going to be completed.

The invention discloses a method for updating switching parameters in the process of soft switching of a terminal among access networks, which comprises the following steps: the access terminal notifies a source access network of a target cell in a target access network required to be switched to; and the source access network acquires the switching parameters of the target cell from the target access network, and updates the switching parameters of the access terminal according to the acquired switching parameters of the target cell. The method of the invention avoids the problems of dropped call, low network performance, switching failure and the like caused by that the switching parameters do not meet the actual wireless conditions when the terminal is in a switching area, increases the success rate of the soft switching of the access terminal, reduces the conditions of dropped call, and enhances the user experience.
