Wireless Network System Figures 1A and 1B illustrate a conceptual diagram of a wireless network system in accordance with an exemplary embodiment of the present invention. The constituent elements of Figures 1A and 1B use the same reference numerals. Referring to Figure 1A, a wireless network system, e.g., a wireless system 10, includes a plurality of stations or terminals 12, an access point or wireless station 14, and a backbone network or a decentralized system 16. A plurality of stations 12 are loaded with a network interface for a wireless LAN to perform a physical layer and a MAC layer in accordance with IEEE 802.11. In the wireless LAN system 10 of FIG. 1A, a plurality of stations 12 are connected. The access point 14 transmits a data frame. The access point 14 performs a wired and wireless network connection function to relay—a frame transmitted from one station to another station. The result. Lu

Detailed system RAN policy or the same or the same LAN base card. The system is used to take the point 12 200828885 14 亍 1 亍 This phase m function w as an Ethernet bridge or switch. The access point 14 basically comprises the same Spirit layer and MAC layer as the station 12 described above. Thus, the access point 14 can perform substantially the same operation as the station 12. As a result, the access point 14 can be considered identical to the station 14 if necessary. The station 1 2 and/or the access point 14 may perform a plurality of types of components related to the operation of the presence service (which has another station and/or access point in a wireless communication system) Used to execute a program related to the presence of a service. The operation associated with the presence of the service may be for at least one of the fellow connection operation or the presence of the partner. The program related to the presence of the service may be at least one of the companion link program or the companion existence program. The means for executing the program associated with the presence of the service may be implemented by software, hardware or a combination thereof at the station 12 or the access point 14. These components perform all or part of the steps, which contain procedures related to the presence of services.

The decentralized system 16 is the hub network that is connected to a plurality of access points 14. The decentralized system 16 typically uses an Ethernet network but can be wirelessly connected to a plurality of access points 14 . The decentralized system 16 can broadly include a router or a switch connected to the Ethernet, and a plurality of servers connected to the wired and wireless internet. Referring to FIG. 1B, the wireless network system, for example, the wireless lan system 1 includes a plurality of stations or terminals 12. The wireless LAN system 1 is directly connected to each station in a point-to-point manner. Therefore, the wireless LAN system shown in FIG. 13 200828885 does not include a separate access point 14 and the distributed system 16, which is different from the wireless LAN system of FIG. 1A. However, in the wireless A plurality of stations 12 in the LAN system 10 can perform the functions of the separate access point 14 and the distributed system 16. Similarly, the function of the split access point 14 and a portion of the distributed system 16 can be ignored. exhausted

Although the wireless LAN system 10 is explained with reference to FIGS. 1A and 1B, in accordance with an embodiment of the present invention, a wireless network system including the wireless LAN system 1 is not limited thereto and may be combined Or a separate system implementation. According to an embodiment of the present invention, the wireless network system can exist independently and interwork between a different wireless network system, a mobile communication network, and a wired and wireless internet network, for example, The wireless LAN system can provide a roaming service by interworking with a wideband code division multiple access (WCDMA). In particular, when the wireless LAN system provides a voice service, a dual band dual mode (DBDM) terminal supporting the wireless [AN and the WCDMA] performs a voice call on the mobile communication to the mobile phone. At the same time, seamless automatic roaming is performed on the wireless LAN system. The wireless Lan system shown in Figs. 1A and 1B can transmit data via a connection process between the stations 12 or between the station 12 and the access point 14. Linking Procedure Fig. 2 is a flowchart showing the connection processing for transmitting data in a wireless LAN system as shown in Fig. ia. Chapter ib 14 200828885 The wireless LAN system and various wireless network systems are partially different from the system of Figure 2. However, the wireless LAN system and various wireless network systems of Figs. 1B and 2 respectively include the connection processing for transmitting the same data. Therefore, the detailed description will be explained later. Referring to Figures 1A and 2, a linking process 20 for transferring data between the station u and the access point 14 includes a scanning process s 1 0, a verification process S 1 2, and an association process S 1 4. The station 1 2 and the access point! 4 A data transfer process sl6 is executed via the processes S10, S12 and S14. The scanning process S10 is a process of finding the peer (Peer) access point 14 using the beacon or the probe message.

The scanning process S10 includes a passive scanning process for searching the access point 14 from the beacon message periodically broadcasted by the access point 14, and an active scanning process for enabling the station 12 to Broadcasting a probe request message or frame according to each channel, and receiving a probe response message (including a person's own service setting ID (SSID), a working speed, and others from the access point 14 ) to select the corresponding access point 14 . The beacon message includes various capabilities (speed, encryption, etc.) that can be supported by the access point 14 and a person's own service setting ID (i.e., SSID). This verification processing S12 checks whether or not the station 12 that selects the appropriate access point 14 in the scanning process S10 is a valid terminal. In other words, the verification process S12 is to negotiate with the access point 14 via a verification procedure and an encryption method. Usually, an open system verification method is used in the verification process S 1 2 . Therefore, the access point 14 unconditionally verifies a verification request from the station. An enhanced verification method includes EAP-TLS, EAP-TTLS, 15 200828885 EAP-FAST, ΡΈΑΡ and others. The association process S14 is a process in which the station 12 is connected to the access point 14 after the verification is successfully completed. The association process S14 means that a same relationship is established between the station 12 and the access point 14. If the association process S14 has been completed, the station 12 can communicate with the other stations 14 via the access point 14. If the station 12 sends the association request message or frame to the access point 14, then the access point is made! 4 To send an association response message (which includes an association ID (AID) associated with other stations) to perform the association process S 14 . The station 12 and the access point 14 perform a data transfer process S16 via the processes S10, S12 and s14. Re-association The association process S 1 4 is approximated to a re-association process. The reconnection process connects the access point associated with the station 12 to other access points. When a signal from an access point 14 associated with the station 12 is obtained

When it is weak, the re-association process creates a new link with a new access point 14. In the re-association, the frame stored to the old access point 14 is transferred from the new access point 14 to the station 12. In detail, if the station 12 sends a re-association request message including an access point 14 address in the current AP to the access point 14, the access point sends a re-association response to the station. 1 2, the re-association response contains the association ID (AID), which is used to logically identify the value of the station 12, and the buffered frame must be delivered to the station 12. The new access ‘point 14 requests the IAP (Intra AP Agreement) for the old access point 14 to send any buffered frames for the station 12. The station 12 and the access point 14 contain a number of components associated with the linking procedure. For example, the station 12 and the access point 14 include a verification component for performing a verification procedure with another station. Such components are implemented by software, hardware or a combination thereof at the station 12 or the access point 14.

The presence of W during the reconnection or re-jj sequence. The communication method in a wireless network according to a specific embodiment, for example, the wireless LAN in the 1A and 1B diagrams, relates to the support capability. The station can send the association request or the re-association request frame (which contains its own location information and location capabilities). According to other embodiments, the communication method in a wireless network is that the station supporting the presence capability can transmit the associated response or the re-association response frame (which contains its own location information and location capabilities). • The station supporting the presence is a plurality of stations 12 or the access point 14, which is substantially like the station 12 in the ία and 1B diagrams, • contains the same physical layer and MAC sublayer. In this specification, the station will be the access point 4 or the station 12 in the 1A, 1 B and 2 diagrams. ♦ In this communication method, the presence parameters, such as Tables 1 and 2, are added to the association request and the reassociation request frame or the message described in Figure 2. The presence parameters, such as tables i and 2, are also added to the associated response and the re-association response frame or as described in Figure 2 2008 28885 #

In Tables 1 and 2, the order in which the parameters are present is defined as free and can be changed. Another information, rather than the presence of parameters, may (or may not) be included in the associated request (response) and the re-association request (response) ) in the frame or message. Figure 3 is a flow diagram of the communication method in accordance with an embodiment. Referring to FIG. 3, the communication method in the wireless network according to an embodiment is related to the association and/or re-association request of the presence parameters as follows.

The station 12 sends the association and/or re-association request with the presence parameter information element to the access point 14' to provide its own capability information or location configuration related to the presence of the station, where the presence parameter The information element includes a location descriptor, which can be considered as a program included in the presence requesting program, which is defined in the IEEE 802.11v series of the WLAN. According to the communication method in the wireless network, for example, the wireless 19 200828885 LAN (WL AN), the station may be opposite to the station during the association request of the associated program or the re-association request of the associated program The self-existence capability or the self-force related to the location information of the station, together with the existence request of the presence service or the response being forwarded together with the presence presence response, or at the access point 14 will be related to the presence of: The ability to exist or the location location capability associated with the station 12 is forwarded to the station 14 prior to forwarding. Thus, the access point 14 can send any location of the station 12 to the station 12 without the presence of information from the station 12, which simplifies the process of providing presence services, thereby enabling rapid service presence. Conversely, the access point 14 also forwards its own presence capabilities associated with the access point 14 or its own location capabilities associated with the access point 14. Therefore, the station 12 can foresee the presence or location capability of point 12. Figure 4 is a diagram showing the name of the communication method according to other embodiments.

Therefore, since the access point 14 foresees the location information of the station 12, the access point 14 provides the capability The station 12 harmonizes the presence service, and the station 12 receives the presence service & which is coordinated with itself, which simplifies the process of providing the presence service to quickly provide the presence service. The calculation or preservation of its own location data for the station 12 is changeable. For example, the station 12 can receive the calculated location from the access point 14 by the beacon or the probe response message. Similarly, the location information of the station 12 can be obtained by the access point 14. To calculate its own location information, where the location information of the access point 14 is received from the access point 14. In other words, the station 12 can calculate its own position by the timing information, wherein the timing information is provided by the access point i 2·. As another example, if the station 12 is equipped with the GPS (Global Positioning System) receiver, the station 12 can receive the signal from the GPS satellite and calculate its own location data by the received signal. As another example, if the station 12 supports DBDM (dual-band dual mode) that can be used for both WLAN and WCDMA or WLAN that works interactively in 3GPP and 3Gpi > 2 21 200828885, the station 12 can Wcdma's base • The station receives its own location information or location information. - Conversely, the access point 14 may also forward its own location profile during the association or re-association. The station 12 can maintain location information for the access point 14. For example, the station 12|| uses the secured location information by the access point 14 to calculate its own location data as described above. ^ Stomach Presence Parameter # 111 component is added to the association and the re-association Φ is requested and/or responded.
