Abstract: A method, an apparatus, and a system for processing a service flow, which belong to the field of communications. Correspondence between a service application attribute and a service application identifier is preconfigured on an NSP board so that after a service flow carrying the service application attribute is received, the service application identifier of the service flow may be determined, which service application corresponding to a service flow may be known according to the service application identifier corresponding to the service flow, and when a plurality of service applications is deployed on an NSP at the same time, a service flow can be correctly sent to a virtual machine of a corresponding service application for service processing.

Abstract: A method, a device, and a system for acquiring application information in a WLAN are provided by embodiments of the present invention. A controller sends a switch request message to an unassociated neighboring AP. The switch request message includes an identifier of a mobile terminal and a designated channel. The unassociated neighboring AP switches from an original working channel of the unassociated neighboring AP to the designated channel and monitors the mobile terminal according to the identifier of the mobile terminal so as to acquire application information.

Abstract: The present invention provides a method for controlling a transmit power in a wireless local area network, a controller, and an access point, including: determining, by a controller, a transmit power range of a radio frequency unit of a first access point AP; determining, by the controller, a packet reception and transmission parameter of each user link of the radio frequency unit according to packet reception and transmission information of the radio frequency unit reported by the first AP; and configuring, by the controller, a transmit power for each user link of the radio frequency unit within the transmit power range according to the determined packet reception and transmission parameter of each user link of the radio frequency unit. Signal interference between devices in a WLAN is reduced while concurrent data transmission capability of the AP is not reduced, thereby improving system transmission performance of the WLAN.

Abstract: The present disclosure relates to a method, an apparatus and a system for updating an Authentication, Authorization and Accounting AAA session. The method includes: receiving an AAA session request sent by a second network access server, where the AAA session request includes a second session identifier and an ERP message; and updating a session according to the second session identifier and a stored first session identifier after successful user authentication that is performed according to the ERP message, where the first session identifier and the second session identifier correspond to the same user. As the session is updated according to the second session identifier and the stored first session identifier, synchronization of session information is ensured, thereby resolving an abnormal session problem that occurs when a home AAA server initiates a session or the network access server uses a session after re-authentication.

Abstract: Embodiments of the present invention disclose a linkage policy implementation method, which includes: receiving, by a linkage proxy module, a linkage policy request delivered by a third-party application service; calling a corresponding protocol converter according to a protocol identifier in the linkage policy request, and performing protocol conversion for the linkage policy request to convert it into a linkage policy request in a set protocol format; and sending the protocol-converted linkage policy request to a linkage client to instruct the linkage client to parse the linkage policy request based on the set protocol and execute linkage policy configuration. With the present invention, a linkage proxy is set to execute protocol conversion of various protocols. Therefore, the cost of the linkage client would not be increased for supporting multiple protocols; and when third-party applications are increased or decreased, it is unnecessary to reconfigure the linkage client.

Abstract: The present invention provides a positioning method, device and system, which are applied to indoor WLAN positioning. A positioning server obtains location service information of APs in a set of APs to be measured; selects three APs to be measured in the set of APs to be measured according to a preset rule, and calculates a first coordinate of a terminal; if a calculated RSSI value of an unmeasured AP is not smaller than a difference between the measured RSSI value and a preset threshold, determines that signals of the unmeasured AP are not affected by reflection; and uses the first coordinate as a location coordinate of the terminal if all the three APs to be measured have been measured, thereby positioning the terminal.

Abstract: The present invention relates to mobile communications technologies, and discloses a method, device, and system for pre-authentication. A pre-authentication device receives a pre-authentication message that carries a pre-authentication option; determines a Mobile Node (MN) to be pre-authenticated according to the pre-authentication message; sends an authentication request message to an Authentication, Authorization and Accounting (AAA) server to request authentication of the MN; receives an authentication response message that is sent by the AAA server, where the authentication response message carries a pre-authentication key used between a Candidate Authenticator (CA) and the MN; and sends the pre-authentication key to the MN. Through implementation of the present invention, the pre-authentication key is obtained before the MN switches to the CA. In this way, security of communication is enhanced, and delay of switching and authentication is shortened.

Abstract: A method, device and system for obtaining a local domain name are provided. A Dynamic Host Configuration Protocol (DHCP) request from a User Equipment (UE) is received, in which the request carries an option for indicating returning a domain name of a local domain where the UE is located; and the domain name of the local domain where the UE is located is obtained according to the DHCP request, and the domain name of the local domain where the UE is located is carried in a DHCP reply message to be returned to the UE. A device and system for obtaining a local domain name are also provided, which solve the problem that a user is incapable of obtaining a local domain name after full authentication, so that a UE can perform fast re-authentication during a handover, thereby reducing a handover delay and improving the user experience.

Abstract: The present disclosure relates to the mobile communication field and discloses a prefix allocation method, a network system, and a Local Mobility Anchor (LMA). With the prefix allocation method, the network system and the LMA provided in the present disclosure, the problem that a shared prefix cannot be allocated to a multi-interface (IF) Mobile Node (MN) is solved. The prefix allocation method includes: receiving a registration request for a second IF of the MN from a Mobile Access Gateway (MAG); obtaining a first Home Network Prefix (HNP) that is already allocated to a first interface (IF) of the MN; and allocating the first HNP shared with the first IF to the second IF. The LMA obtains the first HNP that is already allocated to the first IF and allocates the first HNP to the second IF. In this way, a shared prefix is allocated to the multi-IF enabled MN.

Abstract: A method, system, and Mobile Access Gateway (MAG) for local routing optimization are provided. After receiving a packet sent from a Mobile Node (MN) to a Correspondent Node (CN), an MAG queries for a binding update entry corresponding to the MN. When an MAG local routing flag is set in the binding update entry, the packet is sent to the CN; and when a Local Mobile Anchor (LMA) local routing flag is set in the binding update entry, the packet is sent to an MAG of the CN. With the present invention, the delay in sending the packet from an MN to a CN is shortened, the communication efficiency is increased and the user experience is improved.
