  • Patent number: 10289504
    Abstract: An access control method and system and an access point. When a fault occurs in an access controller (AC), an access point (AP) configures a network-layer interface of the AP according to an Internet Protocol (IP) address and a media access control (MAC) address of the AC that are obtained by means of pre-learning, and then the AP routes a received packet to a Web server on a wireless local area network (WLAN) using the configured network-layer interface, where the packet is used by a first station (STA) to request to access an external server. Therefore, interconnection and interworking among wireless local area networks are implemented, and a breakdown of a wireless local area network caused in a centralized network architecture due to occurrence of a fault in an AC is avoided.

  • Publication number: 20160142222
    Abstract: A data transmission method includes: receiving, by an access gateway, data packets; transmitting, by the access gateway, the data packets to an operator network using a digital subscriber line DSL channel; detecting, by the access gateway, a status of a bandwidth occupied when the data packets are transmitted on the DSL channel; determining, by the access gateway, that the DSL channel cannot satisfy a user requirement and some data packets need to be overflowed; and overflowing, by the access gateway to an LTE channel, the data packets needing to be overflowed, and transmitting the data packets to the operator network using the DSL channel in combination with the LTE channel.

  • Patent number: 9270558
    Abstract: Embodiments of the present invention relate to the communications field and disclose a method, a local gateway, and a system for local voice survivability, to implement local voice survivability without configuring a DNS proxy function on a local gateway or configuring a server on a user terminal. A specific solution is: detecting, according to a preset detection period, an activity state of a server recorded in a server monitoring list, where the server monitoring list records a voice server on an Internet protocol IP multimedia subsystem IMS network in advance; intercepting, when it is detected that all servers in the server monitoring list are in an unavailable state, a service data stream sent by a user terminal to the server; and providing a corresponding service response for the user terminal according to content of the intercepted service data stream. The present invention applies to a process of voice survivability.
