IX. INSTRUCTIONS: TECHNICAL FIELD OF THE INVENTION The present invention relates to performing presence services in a wireless communication system. The wireless communication system is applicable to a mobile device. [Prior Art] The demand for wireless communication has been and has indeed grown dramatically in recent years, and millions of people in the world use wireless communication every day, and use pagers, mobile phones, and wireless personal digital assistants. And his wireless communication products to send, receive and exchange information. Recently, changes in non-communication technology have continued to advance to commercial and personal computers. No communication technology now allows computer users to access and share information and data without being limited by the computer network infrastructure cables traditionally used to connect computing devices. Due to the increased capabilities of wireless networks, laptop and notebook users can perform their work with enhanced mobility. For example, a user can carry his or her laptop from its desktop to a conference room to attend a conference, and still have the ability to access the network, and can access data via one or More data gateways present on the network access the Internet, and all of these actions are restricted to a wired connection. Similarly, mobile computer users often use their portable computers to access their electronic account numbers to determine if there are any unread e-mails, as well as to read and send e-mails. Furthermore, the ability to connect to the Internet's network of people's lines> does not allow mailers to perform their work and other things without having to endure by tradition 5 The poor performance provided by the 6K modem connection, which uses the telephone network to establish communication. Indeed, high-speed Internet access via a WAP is highly anticipated when considering the connection via the use of a traditional 56K modem. As a result, as more and more laptops and notebooks are being prepared to be equipped with integrated wireless network interface cards, there is no doubt that they can be extended in commercial environments, even in home environments. .

A further extension of the use of wireless computer networks now allows laptop and notebook users to use their portable computing devices to access public and private computers away from their own office or home network network. Internet service providers (ISPs), telecommunications companies, and wireless network providers have begun to install W A P into places such as airport lounges, hotel halls, and coffee bars. WAP is preparing to be established in business and other public areas where business travellers and general computer users gather more often. The type of public WAP is often referred to as "hotspots". A typical hotspot allows a wireless computer user to access a computer network via a wireless connection between the wireless network interface card built into the user's computer and the public WAP. The hotspot WAP allows the user to access an IP address associated with the modem or gateway to allow the computer user to access the internet and possibly other local network resources, such as A printer associated with a hotspot.

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 FIG. 1A, a wireless network system, for example, a wireless provider of its location:

The detailed system RAN syllabus or the same or the same LAN 8 374625 system 1 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 802.11. In the wireless LAN system 1A of FIG. 1A, a plurality of stations 12 are connected to the access point 14 to transmit a data frame, and the access point 14 performs a wired and wireless network connection function. Relay—The frame that is transmitted from one station to another. 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. Therefore, the access point can basically perform 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 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 Execution _ related to the existence of the service program. The operation associated with the presence of the service may be at least one of the operation of the fellow (fell〇wing) or the operation 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. The components perform all or part of the steps, including the program associated with the presence of the service β 9 1374625. The distributed system 16 is the hub network, which is connected to a plurality of access points 14. The decentralized system 6 typically uses an Ethernet network but can be wirelessly connected to a plurality of access points 丨4. 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 Figure 1B, the wireless network system, e.g., the wireless system 10, includes a plurality of stations or terminals. The wireless LaN. system i is connected directly to each station in a point-to-point manner. Therefore, the wireless LAN system shown in Fig. 1B 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, the plurality of stations 12 in the wireless LAN system 1 can perform the functions of the separation access point 14 and the distributed system 丨6. 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 Figures 及a 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 can be implemented in combination with or in a separate system. According to an embodiment of the invention, the wireless network system can exist independently and interact with each other in a different wireless network system, a mobile communication network, and a wired and wireless internet network. 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) 10 1374625 that supports both the wireless [αν and the WCDMA] is supported.

The terminal performs a voice call on the mobile communication to the recording, and simultaneously performs seamless automatic roaming on the LAN-less system. The wireless LAN system 10 shown in Figs. 1A and 1B can process data transmission via the connection 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. 1A. Fig. 1B The wireless LAN system and various wireless network systems are partially different from those of Fig. 2. However, the wireless LAN system and the various wireless network systems of Figs. 1B and 2 respectively include the same data link processing for transmitting. Therefore, the detailed description will be explained later. Referring to Figures 1A and 2, a link process 20 for transferring data between the station 12 and the store 14 includes a scan process S10, a card process S12, and an association process S14. The station 12 and the access point perform a data transmission process via the processes S10, S12 and S14. The scan process S10 uses the beacon or the probe to find the peer. The processing of the access point 14 includes a passive scanning process for searching the access point 14 from the beacon message periodically broadcasted by the fetching point 14 to perform an active scanning process. The platform 12 is configured to enable a probe request message or frame according to each channel, and receive a probe back message (including a person's own service setting ID (SSID), one from the access point 14 The speed of operation and others) to select the corresponding access point 14 . The beacon signal is a test of the system 14 14 . The memory and broadcast information and interest 11 1374625 include various capabilities (speed, encryption, etc.) that can be supported by the access point 14 and a person's own service setting ID (ie, SSID).

The verification verification processing S12 checks whether or not the station 12 when the access point 14 is selected as the valid terminal in the scanning processing S10. In other words, the certificate processing S12 is to negotiate with the access point through a verification procedure and an encryption method. Generally, an open system verification method is used in the verification process S. 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 test is successfully completed. The association process S 1 4 means that a same relationship is established between the station 12 and the access point 14. If the association process S14 is completed, the station 12 can communicate with the other stations 14 from the access point 14"

If the certificate is obtained, if the station 1 2 sends the association request message or frame to the storage point 1 4, the access point 1 4 is sent. An associated response message (which includes an association ID (AID) in cooperation with other stations) is used to perform the association process S14. The station 12 and the access point 14 perform a data transfer process S16 via the processes S10, S12, S14. Re-association The association process S 14 is similar to a re-association process. The re-processing is to connect the access point associated with the station 12 to other locations. When a signal from the access point 14 associated with the station 12 is degraded, the re-gate process establishes a new link with the 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-off response to the station. The station 12, the reassociation response contains the association ID (AID), which is a numerical identifier for logically identifying the station 12, wherein the buffered frame must be passed to the station 12. The new access point 14 requests the IAP (Intra AP Agreement) for the old access point 14 to send any 3 buffered frames to 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.

Presence service during association or re-association procedure According to a specific embodiment, a communication method in a wireless network, for example, in the wireless LANs in FIGS. 1A and 1B, is that the station supporting the presence capability can transmit the association. Request or 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). 13 1374625 The station supporting the presence is a plurality of stations 12 or the access point 14, which is substantially the same as the station 12 in Figures 1A and 1B, and includes 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 FIG. These presence parameters, such as Tables 1 and 2, are also added to the associated response and the re-association response message or the message described in Figure 2.

[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 dotllWirelessManagementlmplemented value is true, the ability to support the adjustment category is present. 15 Presence 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. Figure 3 is a flow diagram of the communication method in accordance with an embodiment. Referring to FIG. 3, the communication method 30 in the wireless network according to a specific embodiment is related to the association and/or re-association request of the presence parameters as follows. The frame is forwarded from the station 12 15 1374625 to the access point 14. The station 12 transmits the relationship and/or re-association request with the presence parameter element to the access 14 to provide its own capability information or bit configuration associated with the presence of the station, wherein the presence parameter information The component includes a location descriptor. This can be considered as being included in the presence request procedure, which is defined in the IEEE 802.1 series of the WLAN^

According to the communication method 30 in the wireless network, for example, the LAN-free (WLAN), the station may be related to the existence of the station during the association request of the associated program or the re-association request of the re-association program The presence capability or the location power associated with the location information of the station, along with the existence request of the presence service or the response to the presence request response, or the access point 丨4 will be associated with the station The existing presence capability or location capability associated with the location information of the station 12 is forwarded to the station 14.

The resource point 1 v line new energy 12 is transferred to it, so the access point 14 can send any location information of the station 12 to the station 12 without the presence information from the station 12 This allows the process of providing a presence service to be simplified so that the service can be quickly presented. Conversely, the access point 14 also forwards its own presence capability associated with the access point 14 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 location 12.

Referring to FIG. 4, the communication method 40 in the wireless network according to other embodiments is related to the presence and/or re-association request of the presence parameter in the frame t. The frame is transferred from the station 12 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 14 to provide its own location data, wherein the presence parameter information element includes a location profile. 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 requesting program or the presence advertisement program, which is defined in the IEEE 8 02.1 lv series of the WLAN. According to the communication method 40 in the wireless network, for example, the wireless LAN, the station 12 may be in the presence request or the presence configuration during the association request of the associated program or the reassociation request of the re-association program Before requesting, transfer its own data known to the station 12 to the access point 14

Thus, because the access point 14 anticipates location data for the station 12, the access point 14 provides the presence service that can be harmonized 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 by the location information of the access point 14 17 1374625

In other words, the station 12 can be set by the timing information, wherein the timing information is provided for the access point 12. If the station 12 is equipped with a 4-bit system) receiver, the station 12 can The GPS satellite calculates its own position by the received signal. As another example, if the station 12 supports DBDM (dual-band dual mode) capable of WCDMA or WLAN in which the interworking works, then Station 12 can receive its own location information or location information from the station. Conversely, the access point 14 can also associate or forward its own location data. The station 12 can maintain full information. For example, the station 12 calculates its own bits by the access point: all-position information as described above. The presence parameter information element is added to the association request and/or response. The presence parameter information element is serviced. The format of this information element includes the component ID field and the presence of a sub-component field that blocks the presence of the sub-component described in Grid 3. Therefore, the station 12 operates in association with a wireless communication system.

A value of 0 indicates that the location data object is defined by the binary format described in RFC 3 8 2 5 . A value of 1 indicates that the location data object is defined as a flat text XML defined by the scheme in RFC 4119. A value of 2 indicates that the object at that position is defined as an A S N. 1 code for each X · 6 9 4 . 1 0. Location data block The location data sub-component provides the requested location data. The format of the location data sub-element is as shown in Figure 14. The component ID block contains a value of 10 and the value of the length field is variable.

The marshalling descriptor field indicates the indication in the location data encoding. As shown in Table 14 29 1374625, the position is accurately estimated as an estimate of the increment by 0.1 meter, by a low-order data order (1 i 111 eendia η) 1 6-bit unsigned Defined by an integer. For example, an accurate estimate of +/- 5 units of measurement is represented by the number 0x3 2 (decimal point 50). If the position is accurately estimated to be unknown, the field is set to zero. The location value field contains the location information 'which matches the format defined by the location format descriptor.

In order to indicate whether the location data in the location data field is defined in some precision or format, or when measuring location data in the location data field, the location descriptor field or location source identifier described above Can be used. 1 1. Location ID field or location source identifier field 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 field is a coordinated universal time (UTC) offset that is associated with the location time stamp. The preset time zone offset value is 0 (U T C). The location timestamp field is the time that the location value was determined in UTC, including hours, minutes, seconds, and milliseconds, as shown in Table 15. [Table 15] Octet Description 0-2 milliseconds (0-999) 3 seconds (0-59) 4 minutes (0-59) 5 hours (0 - 2 3) 30 1374625

Stations 12 or 14 that are unable to provide time will set the time zone to 0. The public identifier chain block is provided as one of its compliance with RFC 3 69 3» When a station 12 or 14 forwards an external agent, the public identifier chain is valid for the agent confirmation. The agreement to query a single structure based on the public identifier chain is outside the scope of this standard. The above communication method in the wireless network provides the presence, the presence parameter in the association or reassociation procedure, the association or reassociation procedure is considered to be used in the presence request procedure and defined in IEEE 802.11V Wireless LAN program. Existence Program Referring to Figure 16, the presence program 50 contains the presence details and the presence program S52. The former S50 includes the existence group S54 and the program (S56). The latter S52 contains the presence please. And the presence response procedure S60. Of course, the station 12 and the access point 14 contain a number of related components. Such components may be implemented by means of software, hardware or a combination thereof at 12 points 14 of the station. The presence program provides the presence service, such as instant messaging software, mobile phones, emails, for the wireless communication between the station 12 and the access point 14 in 1A, to be performed (eg, emergency call, lack, Other work, etc.), in the KONE or feature (such as voice mail, video call, action or solid time stamp word value, estimate the location of a position estimate in the information, such as information components, order In the case of the presence of the advertisement, the state program S 50 state request program table program (S 5 8) is present in the program and the type of the access and the 1 B picture (for example, the duration of the communication message, language). 31 1374625 Presence Programs In order to support the presence service, there are two main operations that can be configured between the Peer Stations 12 or 14. The first configuration operation requires the purpose of collecting the necessary information. The periodic exchange of frames is performed to complete a position determination. The second configuration operation is used to establish a location service that periodically provides location estimates to a pair of isochronous stations 12 or 14.

The station 12 or 14 can be included in a beacon or probe request (or response) frame by means of a presence parameter information element, or by including a presence parameter information element in an existing group. In the mode request (or response) message box, configure the presence service. That is, the station 12 or 14 can configure the presence service by including a presence parameter information element in a beacon or probe request (or response) frame, so that the beacon or probe The needle 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 may be a broadcast or unicast frame, and the step of receiving the unicast presence configuration request frame by the station 12 or 14 shall respond to the presence of the configuration response frame response, and the presence configuration response The frame includes a presence parameter information element indicating the result of the request in the presence state sub-element. The step of the station 12 or 14 receiving a broadcast presence configuration request frame should not send an existing configuration response frame. The station 12 or 14 wishes to be able to configure another peer station 12 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 save 32 1374625

The way to provide a bit is achieved by configuring the peer in the request frame. The presence parameter information element can include a location service element that describes the desired action, such as the presence indicator in Figure 5 indicating the presence of the indicated channel field. The presence parameter information element may contain a location service information sub-description as described in Figure 9 and Table 6. Alternatively, the parameter information sub-component may contain an option or a misunderstanding as described in Figure 7 and Table 4. 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 configuration request frame includes a presence status sub-component indicating the request success. The presence state sub-element has four possible status values: success, rejection, and inability. When an STA receives a configuration response frame with a presence; any state other than success, it should be assumed that the original request has not been made and the S T A should take appropriate action based on the state value. For the presence status "failed", the original request can be retried or an alternate request sent. For the "incapable", the STA should not send another configuration request that matches the previous group and is associated with the same B S S . The requesting station can use the station field 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. Set the data sub-parameters and components of the existence of this information, please request the presence of the request for the work, loss of I (the fingering STA backhaul the STA in the state state request service state request 33 1374625 the station 12 or 14 should be a The location descriptor block is included in a presence configuration request frame to provide its location capability. The location description value 2 "CIVIC priority" or 3 "GE0 priority" indicates that the station can support both CIVIC and GEO formats, but The indicated format is preferred. The station should indicate the location resolution, which can support the location resolution descriptor element. Referring to Figure 19, after receiving the presence configuration request, the receiving station 12 or 14 may be present The configuration request is sent to send the presence of the ACK message.

The format of the presence configuration request frame β is as shown in FIG. This category clamp is set to indicate 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 blocked by 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 that is sent to a given destination MAC address. The presence parameter element block contains the presence parameter sub-element.

The allowed presence parameter sub-components for a presence parameter element (which is included in the presence configuration request frame) are the presence indication parameters in FIG. 5, the presence indication channel parameters in FIG. 6, The presence option in Figure 7 and Table 4, the location descriptor field in Figure 13 and Tables 10 through 14, the location data field in Figure 14, the location ID in Figure 15, and the provisioning Business specific information. 2) Presence of configuration response The presence configuration response frame uses the frame format of the mobile frame and is transmitted by a station 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. This category field is set to indicate the value of the wireless network management category. The action field is set to indicate the value of the configured response. The dialog entry field is set to a non-zero value received in the presence configuration response frame to identify the request/response transaction. The presence parameter component field contains the presence parameter sub-element.

The allowable presence parameter sub-components for a presence parameter element (which is included in the presence configuration response frame) are the presence indication parameters in FIG. 5, the presence indication channel parameters in FIG. 6, The presence status in Figure 8 and Table 5, the position descriptor block in Figure 13 and Tables 10 through 14, the position data field in Figure 14, the position ID in Figure 15, and the supplier. Specific information. The allowed presence parameter sub-elements for a presence parameter element (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 12 or 14.

Similarly, the allowable presence parameter sub-elements for a presence parameter element (included in the presence configuration request frame and the presence group cancer response frame) include a plurality of types of location data such that the Station 12 or 14 can provide its own location information to other stations 12 or 14. Of course, before the station 12 transmits the presence configuration request to another station, the station 12 constructs a presence configuration request containing a presence parameter information element, wherein the station 12 can calculate itself Position, the presence parameter information element can include a location descriptor that provides its own location capability 35 1374625 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 a A reward component that is used to report the result of the presence configuration request.

Conversely, after the access point 14 receives a presence configuration request from the station 12, the access point 14 processes the presence action based on the presence configuration request, and if there is a configuration response regarding the presence To be sent to the station 1 2 request, the presence request must be transmitted in response to the presence of the configuration request. Finally, the access point reports the result of the presence response.

From the point of view of the configuration of the access point 14, the access point 14 includes a receiving component for receiving a presence configuration request from a station; a processing component for processing the presence action a transmission component for transmitting a presence configuration response; and a reward component for reporting the result of the presence response", the station 12 or 14 may set the presence in the configuration prior to the presence of the program In the step of service, providing its own presence capability or location information to other stations 12 or 14, which simplifies the next presence procedure. The manner in which its own location is provided in advance has the effect of minimizing or controlling the load of the station 12 or 14 in the next presence procedure. Therefore, the user of the station 12 or 14 can quickly obtain the presence service when needed. In order to maintain the previous configuration of the presence configuration request frame and the presence configuration response message 36 1374625, in addition to the previous location including the location descriptor field or the location data field, this step can be maintained in advance. There is a configuration request frame and a configuration response frame and its own existing capability and location data. Of course, the receiving station 12 or 14 can send the presence configuration response including the ACK message after receiving the presence configuration request, due to the presence of the configuration request. 2. Procedures exist

Referring to Figures 17 and 18, the beacon, the probe request or the probe response in a wireless LAN like the wireless LAN of Figure 1A may include the location for the presence of the parameter information element. The parameter sub-component is allowed to exist in order to execute the same existing program as the presence request or response.

For example, when the station 12 or 14 moves from an ESS (Extended Service Set) to another ESS, the station 12 or 14 can use the above-mentioned parameter information element (which includes at least a location descriptor or location information). The presence parameter information sub-component is added to the beacon, the probe request, or the probe response, such that the station 12 or 14 can provide the location capability or the location information prior to the presence of the program. The ESS (Extended Service Set) means a set of one or more interconnected Basic Service Sets (BSS), and integrates a Local Area Network (LAN) that appears as a single BSS into any one of the BSSs. The logical link control layer at the associated station, as defined in IEEE 802.il. 1) There is a request for the presence request frame to use the mobile frame body format, and is transmitted by the 37 1374625 station 12 or 14 to publish it from the peer-to-peer station 2 or 14 (its support location service) Exist or request its own location information. The station 12 or 14 can periodically advertise its presence by transmitting a presence request frame. The presence request frame can be a broadcast or multicast frame. When the station 12 is not associated with the access point 14, a presence request frame can be transmitted by the station 12. In a BSS, a presence request frame can be sent to the access point 14 (when sent in unicast mode) or can be sent to other access points (when sent as the same broadcast frame). In the wireless network like the wireless LAN (BSS) of FIG. 1A, a presence request frame can be sent to the access point (when sent in unicast mode) or can be sent to other storage. Take points (when sent as the same broadcast frame). The presence of the request frame may not be transmitted in the wireless network t' like the wireless LAN (BSS) of Fig. 1B. The station 12 or 14 in a BSS can transmit a request frame as indicated in the beacon or probe response frame presence parameter information element. When the station 12 or 14 moves from an ESS to another ESS, the station 12 or 14 can transmit a presence request frame indicated by the presence request frame, such as the beacon or the probe response box of the new ESS. The station 12 can request its own location information from the peer station 12 or access point 14 (which supports location services). In order to request the location, the station C shall send a presence request frame with a presence parameter information element (which includes a location descriptor). The location descriptor in the request shall be indicated as ''local.') The station 12 shall indicate the format descriptor of the location data, the parsing description and the cosmic descriptor, and the public juice _ this presence response The encoding descriptor received in the frame.

If the presence request subcomponent is not included, the presence response frame is not sent. The station 12 or 14 may include the no-information field value in the presence request frame to provide radio related information to the receiving station. Radio information can be served at a support location. The station 12 or 14 can include the shift value in the presence request frame to provide mobile related information to the receiving station. This mobile capital can be used to support location services. The station 12 or 14 supporting the location service and receiving a presence request frame (which includes a presence request option sub-element with a radio information bit set to "1") should respond to an presence response frame, which includes a Radio information sub-component that can be used as a radio information field value. A station or 14 that supports location services and receives a presence request frame (which includes a presence request option sub-element with a mobile bit set to "1") should respond to an presence response frame that includes an applicable Moves the moving sub-element of the indicator field value. A station 12 or 14 that supports the location service and receives a presence request frame (which includes a presence request option sub-element with a timing measurement bit set to "1") should respond to an presence response frame, which includes a The time difference timing measurement sub-element is between the time when the request frame has been received from the pair of stations and the time when the corresponding ACK frame has been transmitted to the pair of stations. The station 12 or 14 supporting the presence capability can send an association request line to the station, the station has 12 units, and the like, the 13 1374625 re-association request or the presence request frame to provide its own location information and location. ability. The station 12 or 14 should include a location descriptor sub-element in the presence parameter information element within an association request, re-association request or presence request frame to provide its location capabilities.

The location description value 2 "CIVIC Priority" or 3 "GE0 Priority" indicates that the station 12 or 14 is capable of supporting both CIVIC and GEO formats, but prefers the specified format. If the station 12 or 14 is capable of calculating its own position and desires to provide its location to the access S 1 4, the station 12 may include a location data sub-element into the presence parameter information element. 2) Presence Response The presence response frame is sent in response to a received presence request frame and provides a presence reward parameter to the station 12 or 14. The presence response frame shall be sent by the station 12 or 14 in response to a received presence request frame, wherein the response request bit is set to one. The presence response frame, beacon, and probe response frames provide presence parameters to the station 12 or 14 .

The presence response frame can be sent for several purposes, including providing location information to a pair of station stations 12 or exchanging frames for location calculation purposes. Supporting the presence capability and receiving a presence request frame (which includes a presence request option sub-element), the station 12 or 14 should respond to the presence response frame, wherein the presence response frame includes the presence request option The requested sub-element in the sub-element and a presence-state sub-element indicating the result of the request. 41 1374625 Supporting the location service and receiving a presence parameter information element (which includes a location service parameter sub-component) or a presence request frame (which includes a data description sub-component), the station 12 or 14 should be made to have a response frame In response to the presence of the response frame, a 'descriptor and a location data element are included.

Depending on the options defined in the location descriptor of the request, station 12 or 14 may also include the location source identifier component in the response. The subject should be set to local or remote in the location descriptor depending on the desired location. The station 12 or 14 should set the format, parsing and encoding descriptors in the location descriptor to match the contents of the bit sub-component. If the responding station 12 or 14 is unable to return a value that matches the request (as defined in the location description sub-element), then the station shall send a response with a presence status element indicating that the status element indicates " failure".

The child is asked to have the number of digits in the presence of the action frame for the presence of the response frame to be transmitted by the station 12 or 14 in response to the receipt of the request frame. The format of the frame body is as shown in Fig. 22. The category bar is set to indicate the value of the wireless network management category. The action field is set to indicate the value of the response. The dialog field is set to the "non-zero" value received in the presence request response to identify the request/response transaction. If no management action is placed on hold for the target station, the management pending field is set to 0, and if a management action is placed on the target station and is placed on hold, the management action hold block is set 42 1374625 Stop in) Source and method This bit should be in the number of stations for the number of stations. A value 255 in the management action hold block indicates that the STa stops transmitting the presence request frame. The presence parameter component field contains the parameter sub-elements. For a presence parameter element (which is included in the presence of the response frame, the allowed parameter sub-elements include radio information, timing quantities, moving 'location data, location descriptors, presence status, location identifiers And vendor specific information. Figure 23 is a flow chart of a communication method for the presence request response frame according to another embodiment. Referring to Figure 2 3, the communication party 7 according to another embodiment In the middle, the station 12 or 14 may send a presence request frame to provide its own location data and capabilities through a wireless network (eg, a wireless LAN). After receiving the presence request, the other stations 12 or 14 The ACK (acknowledgement) for the presence request may be sent for the presence request. The format of the stored request frame body includes both the presence capability and the location material in Figure 24. The category paste is set to indicate the The value of the wireless network.Rod management category. The action field is set to indicate the value of the request. The dialog bit is set to identify the non-zero value of the request/response transaction. The token is unique to each of the presence messages sent to a given destination MAC address. The response request is indicated by the presence of a response frame if the response frame is requested by the transmission station. The response frame is not requested. A 43 1374625 Responsive frame is requested in response to the transmitted frame. i The parameter component field contains the presence parameter sub-elements for a presence parameter component (1 In the presence request frame, the allowed parameter sub-components a include the position data block in FIG. 14 and together with the radio information in the n 0 map 'in FIG. 12 The movements are shown in Figure 13, the location descriptors in Tables 9 through 4, the presence options in Figures 7 and 4, and vendor specific information.

Fig. 25 shows an example in which the first station 12a desires to know the existence capability of the second station 12b when the first and second stations 12a or 12b can exchange data with each other through the access point 14.

Referring to Fig. 25, the first station 12a transmits a presence configuration request frame including the location identifier to the presence parameter information elements to the access point 14. As a result, the access point 14 and the second station 12b become aware of the existence capability of the first station 12a before the presence of the service. Conversely, the second station 12b can send a presence configuration response frame having its own capability to the first station 12a via the access point 14.

Of course, the presence configuration request and response frame may include the location data of the station and the presence capability. Both the station 12a or 12b and the access point 14 can know in advance the presence of the station 12a or 12b and the location date. The access point 14 can also provide its own presence capability and location data for both stations 12a or 12b by using the presence configuration request or response frame. Both stations 12a or 12b can calculate their location data by using the location data of the access point 14. Both stations 12a or 12b and the access point 14 can provide their presence and location profiles in advance with each other by using the presence request frame and the presence configuration request and/or response frame. Both the station 12a or 12b and the access point 14 can be associated with each other by using the beacon, the probe request or the probe response frame in Figures 17 and 18 prior to the association procedure. Exchange their presence and location information in advance.

Transmitting the allowed or supported presence parameter information element may be included in one or more of the beacon, the needle request, the presence configuration request, the presence request, the association request, or the reassociation request. Priority of the presence information The above specific embodiment adds all or part of the presence parameter information element including the location descriptor to the location data to the beacon 'probe request, the probe response, the presence configuration The request, the presence request, and the presence response that provides the presence and location information. When a station receives the presence energy and the location data for other stations through the foregoing frame, the priority of the presence information may be the presence echo frame, the presence request frame, the presence configuration response frame, The order of the request frame, the beacon, the probe request, or the probe response frame if the station 12 or 14 receives a new priority related frame having a higher priority than the old existing related frame , then cancel the old configuration and start a one-time configuration. When the relevant frame is unicast and broadcast, the unicast frames may have a higher priority for broadcasting. For example, when a unicast configuration response frame is received and a configuration presence response frame is broadcast, the unicast configuration response frame can have a higher priority than the broadcast.
