The station two hard mail ports 12 and the access point 14 12 200828884 ^ process s 1 0, S 1 2 and s 1 4 to perform a data transmission process si 6. The scan process S10 is The beacon or the probe message is used to find the processing of the peer (peer) access point 14. The sweep processing S10 includes a passive scan process for the periodic broadcast from the store. The beacon message searches for the access point 14 and the & scan processing, which is used to enable the station 12 to broadcast a probe request message or frame according to each channel, and from the access point 丨 4 Receiving a probe response message (including a person's own service set ID (SSID), a speed of operation, and others) to select the corresponding access point 14. The beacon message includes various types of The capabilities (speed, encryption, etc.) supported by the access point 14 and one's own service setting ID (i.e., SSID). The verification process S12 checks the selection of the appropriate access point 14 in the scanning process si Whether the station 12 is a valid terminal. In other words, the verification process S12 is through a verification procedure. And an encryption method is negotiated with the access point 14. Typically, an open system verification method is used in the verification process sj 2. Therefore, the access point 14 unconditionally verifies a verification request from the station. The enhanced verification method includes EAP-TLS, EAP-TTLS, EAP-FAST, PEAP, and others. The association processing S14 is a process, after the verification is successfully completed, the station 12 is connected to the access point 1 4. The association process 8 14 specifically refers to a same relationship established between the station 12 and the access point 14. If the association process S 14 has been completed, the station 12 can communicate with the other stations 14 via the access point 14. If the station 1 2 sends the association request message or frame to the access 13 200828884 point 14 4, the access point i 4 is sent to send an associated response message (including /, other station cooperation association u In the manner of (aID)), the association processing S 14 is performed. The station 12 and the access point 14 perform _ data transfer processing via the processes §1, 812, and S14. ΑΑϋ The association process s 1 4 is approximated to a re-association process. The re-association process connects the access point associated with the station 12 to other access points. * When the signal from the access point 14 associated with the station 12 is weakened, the re-association process A new link with a new access point 14 is then created. - The frame stored in the old access point 14 in the re-association is transferred from the new access point 14 to the station 12. In detail, the right station 12 sends a re-association request message including an access point M address in the current ap to the access point 14 , and the access point sends a re-association response to the 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 frame of the buffer must be delivered to the station 12.

The good service between the new associations u is based on a communication method in a wireless network according to a specific embodiment, for example, in the 1A and 1B diagrams. Wireless LAN, which is about the support capability, the station can issue the association request The re-association request frame (which contains its own location information and location capability). According to other embodiments, the communication method in a wireless network is that the station supporting the presence capability can send the association response or the re-association Responding to the frame (which contains its own location information and location capabilities). The station with the ability to support the station is a plurality of stations 12 or the access point 14, which is substantially the same as in the eighth and iB diagrams. Like the station 12, it contains the same physical layer and MAC sublayer. In this specification, the station will be the access point 14 or the station 12 in Figures 1, 1B and 2. 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 Figure 2. The presence parameters, such as Tables 1 and 2, are also added. The response to the association and the re-association response frame or the message described in Figure 2.

Another information, rather than a presence parameter, may (or may not) be included in the associated request (response) and the re-association request (response) 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 such that the presence parameters are added to the association and/or re-association request in the frame. The frame is transferred from the station 1 2 to the access point 〖4. The station 2 sends the association and/or reassociation request with the presence parameter information element to the access point 1 4 ' to provide its own capability information or location configuration related to the presence of the station. The parameter information element includes a location descriptor (descriptor). This can be considered as a program included in the presence request procedure. The presence request procedure is defined in the IEEE 802.11v series of the WLAN. According to the communication method in the wireless network, for example, the wireless LAN (WLAN) 'the station may be related to the presence of the station during the association request of the associated program or the re-association request of the re-association program Self-existence capability or self-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 at the access point 14 will be related to The presence capability of the station}2 or its location capability associated with the location information of the station 12 is forwarded to the station 14. 17 200828884 Thus, the access point 14 can forward any location information of the station ο 1 2 to the station 12 without a request for presence information from the station σ 1 2 . This allows the process of providing a presence service to be streamlined, thereby providing a presence service quickly. Conversely, the access point 14 also forwards its own presence capability associated with the presence of the access point 14 or its own location capability associated with the access point. 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 related to the association and/or re-association request of the presence parameters as follows. From the station 12 is transferred to the access point 14. The station 12 transmits the association and/or reassociation request with the presence parameter information element to the access point !4 to provide its own location data, wherein the presence parameter information element includes a location material. The location data contains its own location data that matches the format defined by the location descriptor. This can be considered as a program included in the presence request procedure or the presence advertisement program. The program or the presence advertisement program is defined in the IEEE 802.1 lv series of the WLAN. According to the communication method in the wireless network, for example, 'the no green LAN, the station 12 may be during the association request of the associated program or the reassociation request of the re-association program' during the presence request or the presence group Before the request, the data of its own knowledge is transferred to the access point 18 200828884. Therefore, because the access point i 4 foresees the location information of the station 12, the access point 14 provides the energy. The presence service is coordinated with the station 12 and the station 12 receives the presence service coordinated with itself. This simplifies the process of providing a presence service to quickly provide presence services. 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 via the beacon or the probe response message. Similarly, the station 12 can calculate its own location information by using the location information of the access point 14, wherein the location information of the access point 14 is received from the access point 4. 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 丨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 using the received signal. If the station 12 supports

The presence parameter information element is added to the association and the re-association is as in another example WCDMA! 19 200828884 Seeking and/or responding. The presence parameter information element is used for presence and location services. The format of this information element includes a component ID field, a length field, and a presence of a child component block containing one or more of the existing child components described in Table 3.

In another aspect, the access point 14 operates in an access point of a wireless communication system. The access point 14 includes-receiving to receive data in the wireless communication system to another station, and includes presence parameter information including a support location ('GE0') and a city location value ('CIVIC,) A description of the location of the two and a receiving component for use in a wireless communication system. The means for executing the software, the hardware, or a combination thereof in the component access point 14 for executing the program related to the service is implemented. Similarly, the location descriptor information can be determined for the location, indicating the GE0 and the Preference between CIVIC. The location descriptor contained in the parameter information element in the associated (or re-associated) request or response message is not limited to 11 ' but may be variable. For example, the location descriptor can not be described as a token to be 'in operation. In the system transmission, there is a P-position value piece, which uses the system execution component, which uses the data to coordinate the coordinate value information; the line existence is carried out in the structure of the data (frame) to the table 9 meaning “GEO” 29 200828884 and one of “CIVIC”. The location resolution descriptor block has two fields indicating the location resolution (0-3 bits) and the accuracy (4 bits) requested or sent in a response, such as Table 12 and Table 1. Indicated in 3. Bits 5 - 7 are reserved bits. [Table 1 2] Analysis Description 0 Most likely 1 Building analysis 2 AP analysis 3 XY analysis 4-15 Reserved [Table 13] Accuracy Description 0 No accurate estimation 1 Includes accurate estimation

The code descriptor block indicates the location data code, as indicated in Table 14. [Table 14] Coded value Description 0 LCI 1 Text 2 ASN.1 3-255 Reserved 30 200828884 Value 0 ifc - 9 The location data object is defined by the binary format inserted in RFC 3825. The plane value XML defined by the position data object is indicated by the value 1 in RFC 4119. A value of 2 indicates that the object in the position is in the position data of the position 10. The position of the material sub-parameter of the data sub-component Each X.694 is defined as an ASN.1 code. The component provides the requested location information. This position is shown in Figure 14. Set

The component ID block contains a value change. 10, and the value of the length field can be the position of Jingrui # Μ 1 month, estimated as a 0·;! measurement unit (meter) to increase the accuracy of the estimate, A _ ^ low-order data The order (little endian) is defined by the unsigned integer of 16 bits. For example, an accurate estimate of 5 units of measure is represented by the number 0X32 (the decimal point is 5〇). If the position is accurately estimated to be unknown, the block is set to 〇. The location value block contains the location information' which matches the format defined by the location format descriptor. In order to deduct the location data in the location data block, whether it is 4

The accuracy or format is defined, or the location descriptor block or location source identifier described above can be used when measuring the location within the location data block. 11 • Location ID Block or Location Source Identifier The Location Source Identifier sub-element provides the location source identifier. The format of this sub-element is as shown in Figure 15. The time zone offset block is a coordinated universal time (UTC) offset, which is the O (UTC) value of the location time 31 200828884. This bit determines the time, including the one shown. The stamp indicates the association. The preset time zone offset sets the time stamp to the position value that has been in UTC 'hours, minutes, seconds, and leap seconds, as shown in Table 1 5 1 [Table 15] octet description 0-2 milliseconds (0-999) 3 seconds (0-5 9) 4 minutes (0-59) 5 hours (0-23) Stations 12 or 14 that cannot provide time will be set to 〇. The public identifier link field is one that is compliant with RFC3 693. When a station 12 or 14 is a foreign agent, the public identifier is valid for that generation. The agreement based on the public identifier chain is a policy that exceeds the standard of the standard. The communication method in the wireless network is as described in the association or re-association program. The associated program is considered to be defined in the presence order and in 802.11v for wireless programs. The shoe library is present. Referring to Fig. 16, the presence program 5 includes the cable and the presence program S52. The former S50 includes the S54 and the program (S56). The latter S52 contains the string value provided by the time zone and the time stamp, and the location estimate is based on the fact that the location estimate is determined by the location estimate. For the presence information, for example, in the parameter information element, the presence of the process LAN within the process provider, the presence of the configuration file S 5 0 exists, the configuration request program existence request program (S58) 32 200828884 and the presence response program S6 Hey. Of course, the station 12 and the access point 14 contain a number of types of components associated with the presence of the program. Such components may be implemented by means of software, hardware or a combination thereof in the station 2 and the access point 14.

The presence program provides the presence service, such as the type of wireless communication between the station 12 and the access point 14 in FIGS. 1A and 1B (eg, instant messaging software, mobile phone, email), Willingness to communicate (eg, emergency calls, lack, other work, etc.), capabilities or characteristics during communication (eg voicemail, video call, action or fixed, language). The existence of the configuration program In order to support the existence of the service, the main operation of the 14 configuration settings. There are two types of cycles that can be used at the peer station 12 or the first configuration to collect the necessary data for periodic exchange of frames to complete the position determination. This second configuration operation is used to establish a location service that periodically provides location estimates to a pair of isochronous stations 12 or 14. Talk about station 1 2 or 1 4 by including a parameter parameter component in a tag or probe request (or response) frame, or by placing a parameter parameter The presence service is set in the manner in which the configuration request (or response) message is included. That is, the station is i station. 12 or 14 can configure the presence service by enclosing a parameter information element: I in the 4 you or probe request (or response) frame to make the beacon or probe request (or response) The frame performs the same function as described below ★ and can be the same as the owner, _, and request (or response) frame. 1) Presence of configuration request 33 200828884 The presence configuration request frame can be a broadcast or unicast frame, and the station 12 or the step of receiving a unicast presence configuration request frame 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 status sub-element. The step of receiving the broadcast presence request frame by the station 12 or 14 should not send an existing configuration response frame. . The station 1 2 or 1 4 wishes to be able to configure another peer station station .i 2 or 14 to periodically transmit the presence response frame, and for this purpose, by transmitting a presence parameter information element to A beacon, probe response, or presence of a peer in the configuration request frame to achieve the step of providing location data. The presence parameter information element can include a location service information sub-element that describes the desired action, such as the presence indication parameter in Figure 5 and the presence indication channel block in Figure 6. The presence parameter information element may contain a location service information sub-element that describes the desired actions as described in Figures 9 and 6. Alternatively, the presence parameter information sub-component may contain presence request options or vendor specific information as described in Figures 7 and 4. If the frame for initializing the service is a unicast presence configuration request frame, the peer STA should respond to an existing configuration request frame, the presence group cancer request frame including a presence state sub-component, It indicates whether the request was successful.

The presence state sub-element has four possible state values: success, failure, rejection, and inability. When a STA receives a configuration response frame with a presence status indicating any status other than success, then the STA 34 200828884 should assume that the original request has not been made and that S τ A should be based on the returned Appropriate action is taken. For the presence status "failed", the s T a may retry the original request or send an alternate request. For the presence status "incapable j, the STA shall not send another configuration request that is consistent with the previous configuration request and is associated with the same BSS. The requesting station may be used in Figure 9 and Table 6. The location service information sub-components of the station block to start or stop the service. The station capable of supporting the presence 1 2 or 1 4 can send a presence configuration request frame to provide its own location information and location capabilities. 1 2 or 1 4 shall include a location descriptor field in a presence configuration request frame to provide its location capability. The location description value 2 "CIVIC Priority" or 3 "GEO Priority" indicates that the station can support Both CIVIC and GEO ,, but prefer the indicated format. The station should indicate the location resolution, which can support the location resolution descriptor component. Referring to Figure 19, after receiving the presence configuration request, The receiving station 12 or 14 may send the presence configuration including the ACK message in response to the configuration request. The format of the presence configuration request frame body is as shown in Fig. 20. The category barrier is set to indicate The The value of the wireless network management category. The action field is set to indicate the value of the configuration request. The Dialog Token is a non-zero value that identifies the presence of the configuration request/response. (transaction) The dialog token is unique to each existing configuration request frame sent to a given destination MAC address. The presence parameter component block contains the presence parameter sub-element. 35 200828884 for one There are parameter elements (which are included in the existing configuration box), the allowed parameter sub-components are the stored parameters in FIG. 5, the presence indication channel parameters in FIG. 6 , and FIG. 7 and The presence request options in the table, the position field in Figure 13 and Tables 1 through 14, the position data block in Figure 14, the position ID in Figure 5, and vendor specific information. There is a configuration back to the configuration response frame using the mobile frame body format, and the station 12 or 14 is input according to the receipt of a configuration request frame. The format of the existing configuration response frame is 21st. The figure shows the category Set to indicate the wireless network management category value. The action field is set to indicate the presence of a configured response sub-character. The blocked bit is set to be in the presence configuration response frame. a value of zero to identify the request/response transaction. The presence parameter meta-bit contains the presence parameter sub-element. The per-presence parameter is used for a presence parameter element (which is included in the presence configuration return box) The sub-element is the non-parameter in Figure 5, the presence-indicating channel parameter in Figure 6, the presence status in Figure 8 and the table, the position in Figure 13 and Tables 1 to 14 The location data block in Figure 14, the ID in Figure 15, and the vendor-specific information. ^Used for a presence parameter component (which is included in the presence configuration box. The allowed parameter parameters of the internal parameters include a plurality of types of location descriptors such that the station 12 or Μ seeks the information in the location of the pointer 4 and is transmitted by the number. The receipt of the message is in the position of the message. The location of the message can be raised by 36 200828884 for its own existence to other stations 12 or 14. Similarly, the allowable presence parameter sub-components for a 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 data, such that Station 1 2 or i 4 can provide its own location information to other stations 〖2 or 丨4. Of course, before the station 12 transmits the presence configuration request to another station, the station 12 constructs (C0IlsUuct) the presence status request containing a presence parameter information element, wherein the station 12 can calculate its own position. The presence parameter information element can include a location descriptor that provides its own location capabilities and a location profile that provides its own location information. Similarly, after the station 12 transmits the presence configuration request to another station, the station 12 reports the result of the presence configuration request. From the viewpoint of the configuration of the station 12, the station 12 includes a _construction component for constructing a presence configuration request, a transmission component for transmitting the presence configuration request to another station, and The return component is used to report the result of the presence configuration request. Conversely, after the access point 14 receives an existing configuration spray request from the station 12, the access point i 4 is treated with the presence and configuration of the two bases, and if present, There are _ about the existence of 厶μ 隹! If the status response is to be sent to the 誃22 request, it should be received because the configuration request has been received: Finally, the access point returns 1 Gent & 廿 in response to the result. From the viewpoint of the configuration of the access point 14, the access point η is a receiving component for receiving a presence configuration request from a station at 1 匕3 processing; a processing component , which is used to process the presence action; a transfer member for transmitting a 2008 200828884-present configuration response; and a reward component for reporting the result of the presence response. In conclusion, the station 12 or 14 may provide its own presence or location information to other stations 12 or 14 in the step of setting the presence service prior to the presence procedure, which may simplify the next presence procedure. The manner in which the location is provided in advance has the effect of minimizing or controlling the site 12 or 14 in the next presence procedure. Therefore, the station 12 or

Users of 1 4 can quickly get the presence service when needed. In order to be pre-held in the presence message frame and the presence configuration response frame, except for the previous block & that includes the location descriptor field or the location data block, this step can be pre-held The presence group (4) request frame and the presence of the configuration response frame and its own existence capability and location data. / Tian Ran, the receiving station 1 2 or 丨 4 can send the presence configuration response including the ack message after receiving the presence configuration request, due to the configuration request. 2.
