Description

Method, system, and terminal for realizing information interaction presented by wireless local area network user terminals

technical field

The present invention relates to the field of wireless local area network, in particular, to a method, system and terminal for realizing information interaction of user terminals of wireless local area network.

Background technique

In the mobile communication network or Internet network, the presence (PRESENCE) service is to manage the presence information of the user terminal by the network, such as the contact information of the user terminal, current status, equipment information of the user terminal, service and service component information. The user terminal, the equipment of the user terminal, the service and the service components are called the presence entity (Presence entity). The PRESENCE service provides the above information to different observers (Watcher) according to preset rules, and the observer can actively request the information of a presentity, or be notified once the information changes.

For example, when Zhang San arrives at the office, he can set the display information to be closed on the mobile phone, and the office phone and Email are available. The PRESENCE service provides the following information to Li Si as an observer: Zhang San's mobile phone is turned off, the office phone is available, and Email is available. When Li Si needs to contact Zhang San, he can make an office phone call or send an email.

The information of the presentity can be manually set through the user terminal, or can be provided through the network, and the user terminal only needs to set the provision rules and scope of the information. For example, if Li Si needs to talk to Zhang San, he can set and reserve Zhang San's status information, and once Zhang San's information changes to the power-on state, Li Si will be notified. Another example is that when Zhang San actually starts the machine, the system checks the rules set by Zhang San. This information can be provided to Wang Wu, but not to Li Si. The PRESENCE system refreshes the information for Wang Wu, and the information for Li Si remains the same.

Wireless local area network (WLAN) as a supplement to the mobile communication network includes many different technologies. According to the division of frequency bands used, there are IEEE 802.11b technical standards and Bluetooth (Bluetooth) technology for communication in the 2.4GHz frequency band. There are IEEE 802.11a technical standards and ETSI BRAN Hiperlan2 technical standards for communication in the 5GHz frequency band.

Most wireless LANs are used to transport IP packet data packets. Referring to FIG. 1 , FIG. 1 is a schematic diagram of a wireless local area network connection. For a wireless IP network, its basic structure is to use access point (AP) and access control unit (AC) to complete the wireless access of user terminals, and to form an IP transmission network through network control and connection equipment. The WLAN access technology is generally transparent to the upper layer IP.

The wireless local area network can interact with various other network connections, such as the Internet, or the third generation mobile communication (3GPP) network, or other dedicated network connections, and the user terminal can use one or more of these connections.

For user terminals in the mobile telecommunication network or in the Internet network, the observer can obtain the presentation information of the user terminals through the PRESENCE service system, and for the user terminals in the wireless local area Presentation information and its change information are automatically provided to the PRESENCE business system entity in real time. Only when the user terminal logs in to the WLAN network, the user terminal actively visits the PRESENCE business system entity to register and log in. When leaving, the user terminal needs to visit PRESENCE again The service system entity is logged out, so the observer cannot obtain the presence information of the wireless LAN user terminal, and it also brings inconvenience to the use of the user terminal, so that the information of the PRESENCE service system entity cannot be refreshed in time. Refreshing the information of the PRESENCE service system entity artificially by the user terminal is not real-time, and it is also very difficult.
