Referring to FIG. 1A, a wireless network system, for example, a wireless LAN system 10 includes a plurality of stations or terminals 12, an access point or wireless base station 14 and a backbone network or a decentralized system 16.

A plurality of stations 12 are loaded with a network interface card for a wireless LAN to perform operations of a physical layer and a MAC layer in accordance with IEEE 802.il. In the wireless LAN system 10 of Fig. 1A, a plurality of stations 12 are connected to the access point 14 to transmit a data frame. The access point 14 performs a wired and wireless network connection function for relaying a frame from one station to another station. The access point 14 performs the same function as a bridge or switch of an Ethernet. Further, the access point 14 basically comprises the same physical 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. The result 'the access point 14 can be considered identical to the station 14 if necessary. The station 12 and/or the access point 14, which performs operations associated with the presence service (which has another station and/or access point in a wireless communication system), can include a wide variety of components for Execute a procedure related to the existence of services. The operation associated with the presence of the service may be for the companion (feU〇wing) to operate or at least the operation of the companion. The program for the presence of the service may be at least one of the companion link program or the companion existence program. 10 200830913 Such components for teaching the procedures relating to the presence of services 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 通常6 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 10 includes a plurality of stations or terminals 12. The wireless LAN system! 〇 Connect directly to each station in a point-to-point manner. Therefore, the wireless LAN system shown in Fig. b does not include a separate access point 丨4 and the distributed system 166, which is different from the wireless LAN system of Fig. However, a plurality of stations 12 in the wireless LAN system 1 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. Although the wireless LAN system 1 is explained with reference to FIGS. 1a and 1B, in accordance with an embodiment of the present invention, the wireless network system including the wireless LAN system is not limited to It can be implemented in combination with or in a separate system. According to an embodiment of the present invention, the wireless network system can exist independently and interact (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 both the wireless LAN and the WCDMA performs a voice call on the mobile communication record, and At the same time, seamless automatic roaming is performed on the wireless LAN system.

The wireless LAN system 1 shown in Figs. 1A and 1B can transmit data via connection processing between the stations 12 or between the station 12 and the access point 14. Linking Procedure Fig. 2 is a flowchart showing a connection processing for transmitting data in a wireless LAN system as shown in Fig. The wireless LAN system and various wireless network systems of Fig. 1b are partially different from the system of Fig. 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 transmitting data between the station 12 and the access point 14 includes a scan process si, an authentication process S 1 2, and an associated process s 14 . The station 12 and the access point 14 perform a data transfer process sl6 via the processes S10, S12 and S14. The scan process sl0 is the process of using the beacon or the probe message to find the peer (peer) access point 14. The scan process sl0 includes a passive scan process for searching the access point 14 from the beacon message periodically broadcasted by the access point 14, and 12 200830913 an active scan process for the station 12 can broadcast a probe request message or frame according to each channel, and receive a probe response message from the access point 14 (including a person's own service setting ID (SS ID), a working speed, And others) 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. Generally, 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 authentication method includes EAP-TLS, EAP-TTLS, EAP-FAST, PEAP, 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 S 14 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 4, the access point 14 is sent to send an association response message (including an association ID with another station). In the manner of (AID)), the association processing S14 is executed. The station 12 and the access point 14 perform a data transfer process s 16 via the processes S10, S12 and S 1 4 . 13

200830913 Re-association The association processing s 1 4 is similar to a re-association process. This reconnection process connects the access points associated with the station 12 to other locations. When a signal from an access point 14 associated with the station 12 is weakened, the re-association process establishes a 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 includes an access point 14 address in the current APR re-association request message and sends it to the access point 14 4, the access point sends a new association response to the station 1 2, The reassociation response contains the Gate ID (AID), which is used to logically identify the value identifier of the station 12, wherein the buffered frame must be passed to the station 12. The new store 14 requests the IAP (Intra AP Agreement) for the old access point 14 to send any buffered frame for the station 12. The station 12 and the access point 14 contain components related to the type of connection procedure. For example, the station 12 and the access point 14 include an inspection 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. Presence service during association or re-association procedure According to a specific embodiment, a communication method in a wireless network, such as the wireless LAN in FIGS. 1A and 1B, is that the station supporting the presence can transmit the association. Request or the re-association request frame (there is a new escaping, and the re-receiving of the multi-certificate borrowings includes 14 200830913 with 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 existing capability is a plurality of stations 12 or the access points 14 4, and the access points 14 are substantially the same as the stations 12 in the 1A and 1B pictures, and the same physical layer and MAC sub-layer . In this specification, the platform

The access point 14 or the station 12 in the #, ,, ΙΑ, 1B and 2 diagrams. In this communication method, the presence parameters, such as Tables 1 and 2, are added to the association request and the re-association request frame or the message described in FIG. The presence parameters, such as Tables 1 and 2, are also added to the associated response and the re-association response frame or the message described in Figure 2. Sequence Information Note 10 If the network management dot llWirelessManagementlm piemen ted capability value is true, the wireless network management capability is present. 11 Supported adjustments If the entire category dotl IWirelessManagementlmplemented ---- is true, the ability to adjust the category is supported. 12 Existence parameters dotl IWirelessManagementlmplemented 15 200830913

If the value is true and the non-AP has the ability to have a presence report, then the presence parameter element is present. [Table 2] Order Information Note 12 Wireless Network Management Capability If the dotllWirelessManagementlmplemented value is true, the wireless network management capability exists. 13 FBMS Request If the dotllWirelessManagementlmplemented value is true and the FBMS bit in the radio network management capability is set to 1, the FBMS request may be present. 14 Support adjustment category If the dotl lWirelessManagementlmplemented value is true 'the support adjustment category capability exists. 15 Existence parameter If the dotllWirelessManagementlmplemented value is true and the non-AP has the ability to have a return, the existing parameter element is present. The order in which parameters exist in Tables 1 and 2 is defined as free and can be changed. Another information, rather than a presence parameter, may (or may not) be included in the association request (response) and the re-association request (response) frame or message. 16 200830913 Figure 3 is a flow diagram of the communication method in accordance with an embodiment. Referring to FIG. 3, the wireless network is in accordance with a specific embodiment.

The communication method 30 is for the association and/or reassociation request that the presence parameters are added to the frame, and the frames are forwarded from the station 12 to the access point 14. The station 12 transmits 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, wherein the presence parameter information The component includes a -descriptor. This can be considered as a program included in the presence request procedure, which is defined in the IEEE 8〇2 Uv series of the WLAN. According to the communication method in the wireless network, for example, the wireless LAN (WLAN), the station may be associated with the station in the association request of the associated program or the re-association request period of the re-association program The existing self-existence capability or its own location capability related to the location information of the station, together with the existence request of the presence service or the response to the presence of the presence request, or the access, point 14 will be relevant The presence capability of the station 12 or its location capability associated with the location information of the station 12 is forwarded to the station 1 4 t I. Thus, the access point 14 can forward any location information for the station #1 2 to the station 1 2 without requiring a request for presence information from the station. This allows the program that provides the presence service to be simplified &amp; amps, thereby providing a presence service quickly. Conversely, the access point 14 also forwards its own location capability relative to the presence of the access point 14 17 200830913 or its own location capability associated with the location information of the access point 14. Therefore, the station 12 can foresee the presence or location capability of the access point 12. Figure 4 is a flow diagram of the communication method in accordance with other embodiments. Referring to FIG. 4, the communication method 40 in the wireless network according to other embodiments is added to the association and/or the presence parameters of the frame from the station frame. The re-association request sends the presence parameter to the location information of the parameter information component of the access point, and

1 2 is forwarded to the access point 1 $. The association and/or re-association of the information element of the station 12 is to provide its own location information, which includes a location data. The location data contains its own format that is defined by the location descriptor. This can be considered as a program included in the 钫尨7 &amp; + ^ _ I existence procedure or the presence of the advertisement program, the presence of 谙炎+永私序 or the presence of the advertising program defined in the WLAN In the IEEE 802·11ν series. According to the communication method in the wireless network &gt;#, for example, the wireless LAN 'the station 1 2 can be in the ^ *= ir 8 Β ^ t off % private order association request or the re During the re-association request period of the associated private sequence, the self-data to be known to the station 12 is forwarded to the access point 14 before the presence request or the presence configuration request. Since the access point 14 foresees the location data of the station 12, the access point 14 provides the terminal life &amp; ", ', to convene the presence service harmonized with the station 12 and the station receives The presence service coordinated with itself. This makes it possible to provide a presence service simplification to quickly provide presence services. 18 200830913 The location information for computing or maintaining its own for the station 12 is changeable. For example, the station 2 can receive the calculated location from the access point 14 via the beacon or the probe response message. Similarly, the station 12 can be located by the access point 14 Information to calculate its own location information, where the deposit The location information of the point 14 is received from the access point 14. In other words, the station 12 can calculate its own location by the timing information, wherein the timing information is provided for the access point 12. As an 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. Another fc example, if the station 12 supports DBDM (dual-band dual-mode) that can be used for both WLAN and WCDMA, or a WLAN that works in 3Gpp and 3Gpp2, the station can be from the base of the WCDMA. The station receives its own location information or location information. Conversely, the access point 14 can also forward its own location data during the association or re-association. The station 12 can maintain the location information of 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. The presence parameter information element is added to the association and the reassociation request and/or response. In the middle The number of information elements is used for presence and location services. The format of the information element includes a component ID field, a length block, and a presence of a child component block, the presence of the child component block containing one or more of those described in Table 3.

Such components may provide the presence service by means of the presence software, hardware, or a combination thereof, such as &gt; the time zone and the timestamp provided by the string value, passing a location It is estimated that the location is estimated to be outside the base of the position estimate. For the presence information, for example, in the parameter information element, the presence of the LAN within the requesting program: the presence of the configuration program S 5 0 exists in the configuration request program in the requesting program (S58) containing the relevant program station 1 2 and the access implementation. t 1A and 1B in the figure 32 200830913 The type of wireless communication between the station 12 and the access point 14 (eg 'immediate communication software, mobile phone' email), the willingness to communicate (for example, Emergency calls, lacks, other work, etc.), capabilities or characteristics during the communication (eg voicemail, video call, action or fixed, language). In the configuration program In order to support this presence service, there are two main operations that can be configured in the configuration of the peer station 12 or 14. What is required for this first configuration operation is to perform a periodic exchange of frames for the purpose of collecting the necessary data to complete a position determination. This second configuration operation is used to establish a location service' which periodically provides location estimates to a pair of isochronous stations 12 or 14. The station 12 or 14 can be included in a 请求 标 or probe request (or response) frame by means of a presence parameter information element, or by including a presence parameter information element in a presence Configure the presence service by configuring the request (or response) message box. That is, the station 12 or 14 can be configured to set the presence service by including a presence parameter information element in a beacon or probe request (or response) frame, such that the beacon or The probe request (or response) frame performs the same function as the configuration request (or response) frame described below. 1) There is a configuration request. The presence configuration request frame can be a broadcast or unicast frame, and the step of receiving the unicast presence configuration request frame by the station 12 or 14 should respond to the presence of the configuration response frame. The presence configuration response frame includes a presence parameter information element indicating the result of the request in the presence state sub-element. The station 1 2 or 14 receives a broadcast presence configuration request frame should not send a 33

If the frame for initializing the service is a unicast presence configuration box, the peer STA should respond to an existing configuration request frame, and the request frame includes a presence status sub-component indicating Please be successful. The presence state sub-element has four possible state values: failure, rejection, and inability. When a sta receives a configuration response frame with any status other than success, then the original request has not been made and the STA should take appropriate action based on the user/state value. For the presence status "failed", the original request can be resent or an alternate request can be sent. For the name ..., 7", the STA shall not send another configuration request associated with the previous self and associated with the same BSS. For the Gutai 12, the data can be stored or stored. The parameters and components of the device are present. Please request the message. The presence of the STA is required to determine whether it is functioning or not. (This refers to the STA backhaul. The STA • In the state. State request 34

200830913 The requesting station can use the station block of the bit information sub-component in Figure 9 and Table 6 to start or stop the service. The station 12 or 14 supporting the presence capability can send an presence frame to provide its own location information and location capabilities. The station 1 2 or 14 should include a location descriptor block in the configuration request frame to provide its location capability. The location - 2 "CIVIC Priority" or 3 "GEO Priority" indicates that the station is capable of both support and GEO formats, but prefers the indicated format. The station analyzes the position and supports the position resolution descriptor element. Referring to Figure 19, after receiving the presence configuration request, station 12 or 14 may send the presence-containing configuration of the inclusions as a result of the configuration request. The format of the presence configuration request frame body is as shown in Fig. 20, and the category field is set to indicate the wireless network management class value. The action field is set to indicate that there is a configuration request. The Dialog Token block is a non-zero value that identifies the state request/response transaction. The dialog symbol is for each of the presence configuration request frames for a given target MAC address. The presence parameter component field contains the presence parameter sub-element. For the presence of a parameter element (which is included in the existing configuration box), the allowed parameter sub-element is the non-parameter in FIG. 5, the presence indicator channel parameter in the figure, FIG. And the presence request option, the descriptor block in the 1st and 3rd graphs and the table 1 to the 4th, the position data field in the 14th graph, and the iS state in the j5 service state request CIVIC should mean that it should not receive ACK: the value of the identification. The presence group is sent to the % unique 〇 request message presence indicator. Table 4 Location Map 35 200830913 Location ID and vendor specific information. 2) Presence of configuration response The presence configuration response frame uses the mobile frame body format and is transmitted by station port 12 or 14 in response to the receipt of a configuration request frame. The format of the presence configuration response frame is as shown in Figure 21. The class block is set to indicate that the value of the wireless network management class action bar is set to indicate the presence of a configured response value. The dialog block is determined by 2 to be a non-zero value received in the presence configuration response frame to identify the request/response transaction. The presence parameter element block contains the presence parameter sub-element. For the presence of a parameter element (which is included in the presence configuration back library), the allowed parameter sub-elements are the presence parameter in FIG. 5, and the presence indicator channel in FIG. The presence status of the parameter, 帛8 diagram and table ^, the position descriptor field in the 13th picture and the table 汉口汉衣格1 0 to 1 4, the position data block in the 14th picture, in the Figure 15 shows the location ID and vendor specific information. The allowable presence parameter sub-elements for the presence-parameter element (which is included in the presence configuration request frame and the presence configuration response frame) include a plurality of types of location descriptors such that the station 12 Or 14 may provide its own presence to other stations 2 or 14.
