Abstract:
The present invention discloses a method of notifying an alert status. The method includes using at least two binary alert status indication fields to indicate alert status information; changing a value of the alert status indication field when alert information is changed; and periodically sending the alert status information. The alert status indication field in a interworking element of a beacon frame is extended so that the status of the emergency alert is detected, the change to the emergency alert status is reflected by the value of the extended alert status indication field, and the change to the emergency alert can be detected and handled in a timely manner.
Abstract:
Embodiments of the present invention provide a method for implementing local routing of traffic, a base station and a system are provided, which relate to the field of communications technologies. The method for implementing local routing of traffic includes: judging whether local routing processing is performed on an uplink traffic flow of a first terminal that serves as a sending end; if it is judged as yes, updating a key of the uplink traffic flow of the first terminal and/or a key of a downlink traffic flow of a second terminal that serves as a receiving end to a public key; forwarding an encrypted data packet of the uplink traffic flow of the first terminal to the second terminal through the downlink traffic flow of the second terminal, where an encryption and decryption operation is not performed on the encrypted data packet before the forwarding or during the forwarding.

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:
A redirection method, a redirection device, and a communication system in the field of communication technology are provided. The redirection method includes the following steps: A femto access point (FAP) receives a message, in which the message contains information of a service required by a terminal. After the FAP determines that it does not support the service, the FAP acquires information of base stations supporting the service. The FAP sends the information of the base stations supporting the service to the terminal, so as to enable the terminal to determine a target base station according to the information of the base stations supporting the service. Therefore, the terminal is redirected to the target base station supporting the service required by the terminal, and efficiency of implementing the required service by the terminal is increased.
Abstract:
Embodiments of the present invention disclose a method for reconfiguring a micro base station and a corresponding micro base station to solve a radio frequency conflict of the micro base station, so that a radio frequency conflict can be solved, and meanwhile, service continuity on a currently served wireless terminal can be ensured. The provided method for reconfiguring a micro base station includes: obtaining a reconfiguration parameter of a radio frequency; sending an indication message to a wireless terminal that is served, where the indication message carries an identifier of the micro base station and a radio frequency parameter that is to be used after reconfiguration, or, the indication message carries an identifier of a neighboring base station of the micro base station and a radio frequency parameter that is used by the neighboring base station; and performing radio frequency reconfiguration according to the reconfiguration parameter of the radio frequency.
Abstract:
The present invention provides a method and system for querying parameter information, and an apparatus for returning parameter information. The protocol layer that receives a query request establishes a correspondence between an acquired parameter value and a parameter name and returns the parameter value and the corresponding parameter name to the protocol layer that sends the query result. This can decrease the complexity of implementing the query mechanism. In addition, with the present invention, the MIH layer can also notify the upper layer/MIH users/NMS entity of the query result when returning the queried state information to the upper layer/MIH users/NMS entity.
Abstract:
A method for power management in handover between heterogeneous networks comprising: an MIH layer obtains power information and provides it for an MIH user layer; the MIH user layer determines the handover policy according to the power information. In various embodiments of the disclosure, the MIH layer triggers an event so that the MIH user layer can obtain power information, and select a lower-layer network connection automatically according to the current power status, thus implementing handover; the MIH user layer sends a query request to the MIH layer to obtain power consumption parameters from the network, and selects a lower-layer network connection according to the power consumption and the current power status, thus implementing handover and making more accurate and effective decisions in the handover.
