Wireless network system, a mobile communication network, male-female & A && and wired and wireless internet interwork, such as 'the wireless LAN system can be multi-stored with a wide frequency code A roaming service is provided in a manner that (WCDMA) fathers work together. In particular, when the wireless LAN system provides a voice service, a dual band dual mode (DBDM) 10 200833142 terminal supporting the wireless [AN and the WCDMA] performs voice on the mobile communication record. Call and simultaneously perform seamless automatic roaming on the LAN system. The wireless lan system 10 shown in Figs. 1A and 1B can transmit data via a connection process between ten stations 12 or between the station 12 and the access point I*. The connection process i is a program diagram, and the description thereof is used in the first one.

The connection processing process of the transmission data in the wireless LAN system. The wireless LAN system and various wireless network systems of Fig. 1B are partially different from the system of Fig. 2. However, the wireless system and various wireless network systems of Figs. 1B and 2 respectively include the linking process for transmitting the same data. Therefore, the detailed description will be explained later. The link processing 20 of the data between the points 14 includes a scan process S1, a process S12, and an association process S14. The station 12 and the access point are executed by the processes S1Q, si2 and the data transmission process. "Scan processing Sl0 is to use the beacon or the probe to find the peer (where P is called access point 14). The scan g S10 includes a passive scanning process for taking points. 1 4 periodic itching X save one, K broadcast beacon information search for the access point 14, to a active scanning process, the complex probe is broadcast according to each channel from the two twist ... or frame, and from The access point 14 receives - probe response = ^ = : its own service settings, the operating speed, and selects the corresponding access point 14. The beacon message 11 200833142 includes various access points that can be accessed by the access point 1 4 supported capabilities (speed, encryption, etc.) and someone's own service settings ID (also known as 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 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 S 14 is a process that 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 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 point 14 4, the access point 14 is sent to send an associated response message (including the association with other stations) The ID (AID)) manner is executed to perform the association processing S 14 . The station 12 and the access point 14 perform a data transfer process S 16 via the processes S10, S12 and S 1 4 . Re-association The association process S 1 4 is approximated to a re-association process. The reconnection process connects the access point associated with the station 12 to other access points. When a signal from the access point 14 associated with the station 12 is degraded 12 200833142, the re-association 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-association response to the The station 1 2, 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 buffered frames for the station 12. The station 12 and the access point 14 contain a number of components associated with the linking procedure. For example, the station 12 and the access point 14 include a verification component for performing a verification procedure with another station. Such components are implemented by software, hardware, or a combination thereof at the station 12 or the access point 14. The presence service during the association or re-association procedure is based on a communication method in a wireless network according to a specific embodiment. For example, in the wireless LAN in the first and second diagrams, the station can transmit the support capability. The association request or the re-association request frame (which contains its own location information and location capabilities). According to other embodiments, the communication method in a wireless network is that the station supporting the presence capability can transmit the associated response or the re-association response frame (which contains its own location information and location capabilities). 13 200833142 The station supporting the presence is a plurality of stations 12 or the access point 14'. The access point 14 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 1A, 1B and 2. In this communication method, there are parameters such as Tables 1 and 2, μ & Child Request and the Reassociation Request frame or the information shown in Figure 2. These presence parameters, such as Forms 1 and 2, are also added to the Stomach_Link Response and the Re-Response Response Frame or the message described in Figure 2. [Table 1] Order Information ---- Note 10 If the network management dotl lWirelessManagementlmpIemented capability value is true (true), the wireless network management capability is --·~'~--- exists. 11 Support If the entire category dotl lWirelessManagementlmpIemented is true, the ability to support the adjustment category is present. 12 Existence parameter dotl lWirelessManagementlmpIemented The value is true and the non-AP has Presence Reporting capability, then the existence -J parameter element is present. 14 200833142

In Tables 1 and 2, the order in which the parameters exist 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 an embodiment is related to the association and/or re-association request of the presence parameters as follows. From the station 1 2 15 200833142 is transferred to the access point 14 . The station 12 sends the association and/or reassociation request with the presence parameter information element to the access point 14 to provide its own capability information or location configuration associated with the presence of the station, wherein the presence parameter The information element includes a location descriptor. This can be considered as a program included in the presence requesting program, which is defined in the IEEE 802.11v series of the WLAN.

According to the communication method 30 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 12 or its location capability associated with the location information of the station 12 is forwarded to the station 14. Thus, the access point 14 can forward any location information of the station 12 to the station 1 2 without requiring a request for presence information from the station 12. This simplifies the process of providing a presence service, thereby providing a presence service quickly. Conversely, the access point 14 also forwards its own presence capabilities related to the presence of the access point 14 or its own location capabilities 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. 16 200833142

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. It is transferred from the station 12 to the access point 14. The station 12 sends 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 requestor or the presence advertisement program. The presence request procedure or the presence advertisement program is defined in the IEEE 802.1 1V 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 association request of the associated program or the re-association request of the re-association program' during the presence request or the presence configuration Before requesting, 'transfer its own data known to the station 12 to the access point 14 〇 Therefore, since the access point 14 foresees the location information of the station 12, the access point 14 provides the capability and the station 12 Coordinating (harm〇nize) the deposit service, and the station 12 receives the presence service coordinated with itself. This child's procedure for providing presence services is simplified to provide a presence service quickly for the station 12 to calculate or preserve its own location... change. For example, the station 12 can receive the calculated location from the access point by the probe response message. Similarly, the location 12 can be accessed by the location information of the access point. Calculate its own position " 17 200833142 The location information of the access point 14 is received from the access point 〖4. The station 12 can calculate its own position by the timing information, wherein the timing information is provided for the access point 12. As another example, if the station 12 is equipped with the GPS (Global Positioning System) receiver, the station i 2 can receive the signal from the Gps satellite and calculate its own by the received signal. Location data.

As another 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 12 can be from the WcdmA. The base station receives its own location information or location information. Conversely, the access point 14 may also switch its own location profile during the association or re-association. The platform! 2 can save the position of the access point 丨 4. For example, the station 1 2 uses the secured location information by the access point i 4 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. The presence parameter information element is used for presence and location services. The format of this information element includes a component ID block, a length block, and a sub-component field that contains one or more of the existing sub-elements described in Table 3. And another station executes a certificate component for 'which is used to receive a plurality of message elements from a station ^. Therefore, the station 1 2 operates in association with a wireless communication system.

The station includes a transmission component for transmitting data to another station in the wireless communication system, wherein the data includes presence parameter information including a support geographic coordinate value ('GEO') and a city location value of 27 200833142 ('CIVI c ') both location descriptor information; and an execution component for performing a presence operation in a wireless communication system.

In another aspect, the access point 14 performs an access point access operation in a wireless communication system. The access point 14 includes a receiving component for receiving data to another station in the wireless communication system, wherein the data includes presence parameter information, and the presence parameter information includes a support geographic coordinate value ('GEO') and Location descriptor information for both city location values ('CIVIC'); and a receiving component for performing a presence operation in a wireless communication system. The means for executing the program associated with the presence of the service may be implemented by means of software, hardware or a combination thereof in the access point 14. Similarly, the location descriptor information can be constructed for the location profile, indicating a preference between the GEO and the CIVIC. The location descriptor included in the presence parameter information element of the associated (or re-associated) request or response message (frame) is not limited to Tables 9 through 1, but may be variable. For example, the location descriptor can define only one of "GEO" and "CIVIC." The location resolution descriptor block has two intercept bits that indicate the location resolution (0-3 bits) and the accuracy (4 bits) requested or sent in a response, such as table 12 and table.

For example, an accurate estimate of +/- 5 units of measure is represented by the number 0x32 (decimal point 50). If the position is accurately estimated to be known, the field is set to 〇. The location value field contains the location material that matches the format defined by the location format descriptor. In order to indicate whether the location data in the location data block is defined by a certain degree or format, or when the location data in the location data field is measured, the above location descriptor field or location source identifier is used. . 1 1 · Location ID Block or Location Source Identifier Field The Location Source Identifier sub-element provides the location source identifier. The format of the sub-element is as shown in Figure 15. The time zone offset block is a coordinated universal time (UTC) offset that is associated with the location stamp. The preset time zone offset value is O(UTC). The timestamp block is the time that the position value was determined in UTC, including hours, minutes, seconds, and leap seconds, as shown in Table 15. The meta-tests are not included. [Table 15] Octet Description 0-2 Leap seconds (0-999) 3 seconds (0-59). 4 minutes (0-59) 5 hours ( 0-23) 30

200833142 Stations 12 or 14 that are unable to provide time will set this to 0. The public identifier chain block is one that complies with RFC3693. When a station 12 or 14 forwards an external agent, the public identifier chain is valid for that agent. The agreement to query the underlying structure based on the public identifier chain is beyond the scope of this standard. The above communication method in the wireless network provides the presence of the association or re-association procedure as in the association or re-association procedure is considered to be defined in the presence request sequence and in ΙΕΕΕ802·11ν for wireless [ΑΝ Program. The existence procedure 庠 Referring to Fig. 16, the presence program 5〇 contains the deposit name and the existence program S52. The former S50 contains the presence S54 and the program (S56). The latter S52 contains the presence and the presence response procedure S60. Many types of components. Such components may provide the presence service by means of the presence of software, hardware or a combination thereof in the rabbit point 14, such as < wireless between the station 1 2 2 and the access point 14 Through instant messaging software, action Ray Leo, email), (for example, emergency beer called ', 1 lack, other work, etc.) Force or characteristics (such as voice mail. 9 side pieces, video call, line area and time The stamp is used for the string value, and the position estimate is based on the location of the estimated position report.

Service, there are two main operations that can be set in the same level of the peer-to-peer station. The first-configuration operation = the purpose of collecting the necessary information, and the cycle of the frame is exchanged for a position determination. The second configuration operation system is used Establishing a location to periodically provide location estimates to a pair of stations 12 or 14 may be requested by a parameter information element or probe (or response) frame, or The presence parameter information element is included in the configuration request (or the way back to $) to configure the presence service. That is, the station 12 or 14 can be enclosed by the _ presence parameter 3 Or the party in the probe request (or response) frame sets the presence service so that the beacon or probe request (or the backhaul line is the same as the configuration request (or response) frame as described below) There is a configuration request. The presence configuration request frame can receive a configuration response request for a broadcast or unicast frame 12 or 14 to receive a unicast presence configuration request frame. The frame includes a presence parameter in the status sub-component. The parameter information element 1 2 or 14 receives a broadcast presence configuration request frame. There is no configuration response frame. The station 12 or 14 hopes to group State sets another peer: or 1 4 to periodically transmit the existence Responding to the frame, and in order to send a parameter information element to a beacon, probe station 12 or for the 'to complete the service, the piece is included in the frame by the Tengyi I. Meta-style to configure) frame function. The station is not in existence for the existence group. The station should send one (the station 12 purpose, can respond or save 32

200833142 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 indication in Figure 5 indicating the presence of the channel block in Figure 6. The presence parameter information element may contain a location service information sub-description as described in Figure 9 and Table 6.

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 a S T A receives a configuration response frame with the presence of 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 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. Set the data sub-parameter parameters and components. The existence of this parameter exists. Please ask if there is any power or loss. (This refers to the STA backhaul. The STA requests the service state request in the state state. 33 200833142 The station 1 2 or 1 4 A location descriptor field should be included in the configuration request frame to provide its location capability. The location 2 "CIVIC first" or 3 "GEO first" indicates that the station can both support and GEO format, but The indicated format is preferred. The station resolves the location and can support the location resolution descriptor component. Referring to Figure 19, after receiving the presence configuration request, the station σ 12 or 14 may have a configuration request And sending the configuration of the presence of the message.

Of course, before the station 12 transmits the presence configuration request to another station a, the station 12 constructs the containing one. There is a configuration request for the presence of a parameter information, wherein if the station 12 is capable of calculating its own position, the presence parameter information element can include a capability to provide its own position 35

A location descriptor for 200833142 and a location profile that provides information about its location. 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 component 'for constructing a presence configuration request; a transmission member for transmitting the presence configuration request to another station; A reward component that is used to report the result of the presence configuration request. Conversely, after the access point 14 receives a presence group request from the station 12, the access point 14 is processed in the action based on the presence configuration request and there is a ^ on the right group. If the status response is to be sent to the station 1 2 request, then the presence of the group cancer request should be transmitted because the configuration request has been received. Finally, the access point reports the presence of the response. According to the configuration of the access point 14, the access point 14 includes a receiving component for receiving an existing group from a station. State request; processing component for processing the presence action; a transport component for the presence of a configuration response; and a reward component for reporting the result of the store response. As a result, the station 12 or 丨4 can provide its own presence or bit information to other stations 12 or 14' in the step of setting the presence service prior to the presence of the program, which simplifies the next presence procedure. The manner in which it provides its own location has the effect of minimizing the load on the station 12 or 14 in the next presence procedure. Therefore, the user of the station 12 14 can quickly obtain the presence service when needed. In order to maintain the presence of the configuration request frame and the presence of the configuration response, the station is configured to store the data in the group prior to or in the box 200833142, in addition to including the location descriptor block or the location The previous fields outside the data field, this step can pre-maintain the presence configuration request frame and the presence of the group response frame and its own presence capability and location data. Of course, the receiving station 12 or 14 can send the presence configuration response including the A c κ message after receiving the presence configuration request, due to the presence of the configuration request. 2.
