Description
Technical field
The present invention relates to the WLAN (wireless local area network) field, specifically, relate to a kind of method, system and terminal that realizes that wireless local network user terminal presentation information is mutual.
Background technology
In mobile radio communication or Internet network, presenting (PRESENCE) business is the situation that the presents information of being come managing user terminal by network, for example facility information of the contact method of user terminal, current state, user terminal, business and professional composition information.The equipment of user terminal, user terminal, business and professional composition are called as together and present entity (Presence entity).PRESENCE professional above-mentioned information according to preset rule, offer different observer (Watcher), the observer can information that presents entity of active request, in case or predetermined information change and just obtain notifying.
Arrived office such as Zhang San, he can set presentation information is that mobile phone cuts out, and office telephone can be used, and Email can use.The PRESENCE business provides following information to the Li Si as an observer: Zhang San's mobile phone cuts out, office's words are available, Email can use.When Li Si need get in touch Zhang San, then can dial office telephone, or send Email.
The information that presents entity can artificially be set by user terminal, also can provide by network, and provide rule and scope that user terminal is set this information get final product.Need converse with Zhang San such as Li Si, can set predetermined Zhang San's state information, just notify Li Si in case Zhang San's information-change is an open state.During again such as the actual start of Zhang San, the rule that Zhang San is provided with is checked by system, and this information can offer king five, but can not offer Li Si.The PRESENCE system then refreshes the information of giving king five, and Li Si's information is remained stationary.
Wireless lan (wlan) replenishes as mobile radio communication, has comprised multiple different technologies.Divide according to the frequency range of using, adopt the 2.4GHz frequency range to communicate by letter, IEEE 802.11b technical standard is arranged, and bluetooth (Bluetooth) technology.Adopt the 5GHz frequency range to communicate by letter, IEEE 802.11a technical standard and ETSI BRAN Hiperlan2 technical standard are arranged.
Most of WLAN (wireless local area network) all is used for transmitting the IP packet data package.Referring to shown in Figure 1, Fig. 1 is the WLAN (wireless local area network) connection diagram.For a Wireless IP network, its basic structure is to utilize access point (AP) and access control unit (AC) to finish the wireless access of user terminal, connects to form the IP transmission network by network control and connection device.The WLAN access technology generally is transparent for the IP on upper strata.
