A plurality of stations 12 load a network interface card for the wireless LaN to perform a physical layer and a Mac layer operation in accordance with IEEE 802.11. In the wireless LAN system 1A of Fig. 1A, a plurality of stations 2 are connected to the access point 14 to transmit a data frame. The access point 14 performs a wired and wireless network connection function for relaying - transmission of frames from one station to other stations. The access point 14 performs the same function as a bridge or switch of an Ethernet. Further, the access point 14 basically comprises the same physical layer and MAC layer as the station 12 described above. Thus, the access point 14 can operate substantially the same 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 the _wireless communication system), may include a variety of components for Execute a procedure related to the existence of services.

These components perform all or part of the steps, which contain procedures related to the presence of services.

The decentralized system 16 is the hub network that is connected to a plurality of access points 14 . The decentralized system 16 typically has an Ethernet network but can be wirelessly connected to a plurality of access points 14 . The decentralized system 16 can broadly include a router or a switch connected to the Ethernet, and a plurality of servers connected to the wired and wireless internet.

Referring to FIG. 1B, the wireless network system, for example, the wireless LAN system 10 includes a plurality of stations or terminals 12. The wireless LAN system 10 is directly connected 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 1 6, which is different from the wireless LAN system of Fig. 1A. However, a plurality of stations 12 in the wireless L AN system 10 can perform the functions of the separate access point 14 and the distributed system 16. Similarly, the function of the split access point 14 and a portion of the distributed system 16 can be ignored. Although the wireless LAN system 10 is explained with reference to FIGS. 1A and 1B, according to an embodiment of the present invention, the wireless network system including the wireless LAN system 10 is not limited thereto and may be It is implemented in combination with or in a separate system. According to an embodiment of the present invention, the wireless network system can exist independently and interwork between 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, the wireless LAN and the WCDMA are supported. Both dual-band dual mode (DBDM) terminals perform voice calls on the mobile communication to the recording, and simultaneously perform seamless automatic roaming on the wireless LAN system.

The wireless LAN system 10 shown in Figs. 1A and 1B can transmit data via a connection process between the stations 12 or between the station 12 and the access point 14. Linking Procedure Fig. 2 is a flowchart showing a connection processing for transmitting data in a wireless LAN system as shown in Fig. The wireless LAN system and various wireless network systems of Fig. 1B are partially different from the system of Fig. 2. However, the wireless LAN system and various wireless network systems of Figs. 1B and 2 respectively include the connection processing for transmitting the same data. Therefore, the detailed description will be explained later.

Referring to Figures 1A and 2', a linking process 20 for transmitting data between the station 12 and the access point 14 includes a scanning process S10, an authentication process S12, and an association process S14. The station 12 and the access point 14 perform a data transmission process s 6e via the processes S10, S12 and S14. The scan process S10 uses the beacon or the probe message to find the peer. (peer) processing of access point 14. The scanning process S10 includes a passive scanning process for searching the access point 1* from the beacon message periodically broadcasted by the access point 14, and 12 1356647 an active scanning process for the platform 12 can broadcast a probe request message or frame according to each channel, and receive a probe response message (including one's own service setting ID (SSID)' from the access point 14 - operating speed, and other In order to select the corresponding access point 14 . The beacon message includes various capabilities (speed, encryption, etc.) that can be supported by the access point 14 and a person's own service setting ID (i.e., SSID). This verification processing S12 checks whether or not the station 12 that selects the appropriate access point 14 in the scanning process S10 is a valid terminal. In other words, the test

The certificate processing S12 is to negotiate with the access point 14 through a verification procedure and an encryption method. Generally, an open system verification method is used in the verification process S 1 2 . Therefore, the access point 14 unconditionally verifies a verification request from the station. An enhanced authentication method includes EAP-TLS, EAP-TTLS, EAP-FAST, PEAP, and others. The association process S14 is a process in which the station 12 is connected to the access point 14 after the verification is successfully completed. The association process S·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, and the station 12 can communicate with the f station γ 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 I 4 is sent to send an associated response message (including the association with other stations) The association process S14 is performed by means of ID (AID). The station 12 and the access point 14 perform a data transfer process S16 via the processes S10, S12 and S14. 13 1356647

Re-association The association process S14 is similar to a re-association process. This reconnection process connects the access points associated with the station 12 to other locations. When a signal from an access point 14 associated with the station 12 is weakened, the re-association process establishes a link with a new access point 14. In the re-association, the frame stored to the old access point 14 is transferred from the new access point 14 to the station 12. In detail, if the station 12 sends an access point 14 address in the current AP to the access point 14 to the access point, the access point sends a new association response to the station. The re-association response contains the Gate ID (AID), which is used to logically identify the value identifier of the station 12, wherein the buffered frame must be passed to the station 12. The new store 14 requests the IAP (Intra AP Agreement) for the old access point 14 to send any buffered frame for the station 12. The station 12 and the access point 14 contain components related to the type of connection procedure. For example, the station 12 and the access point 14 include an inspection component for performing a verification procedure with another station. Such components are implemented by software, hardware, or a combination thereof at the station 12 or the access point 14. Presence service during association or re-association procedure According to a specific embodiment, a communication method in a wireless network, such as the wireless LAN in FIGS. 1A and 1B, is that the station supporting the presence can transmit the association. The request or the re-association request frame (which is related to the acquisition of the new re-scheduled multi-certificate loan) contains 14 (S) 1356647 with its own location information and location capabilities. According to other embodiments, the communication method in a wireless network is that the station supporting the presence capability can transmit the associated response or the re-association response frame (which contains its own location information and location capabilities).

The station supporting the 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 1 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. The presence parameters, such as Tables 1 and 2, are also added to the associated response and the re-association response frame or the message described in Figure 2. [Table 1] Sequence Information Note 10 If the wireless network management dotl IWirelessManagementlmplemented capability value is true (true), the wireless network management capability is present. 11 Support If the entire category dotl IWirelessManagementlmplemented is true, the ability to adjust the category is supported. presence. 12 Existence parameters dotl IWirelessManagementlmplemented

In Tables 1 and 2, the order in which 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. 16 C S ) 1356647

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 that the presence parameters are added to the message, the frame is from The station is forwarded to the access point 14. The station 12 transmits the association and/or reassociation 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 element Includes a location description (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 14 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. Therefore, the access point 14 can send any location information of the station 12 to the station 12 without requiring a request for presence information from the station 12, thereby simplifying the process of providing the presence service, thereby enabling the service to be quickly provided. . Conversely, the access point 14 will also be associated with the access point 14 of the box 12 resource point 1 v line new energy 12 which is converted to its own presence capability or related at 17 1356647 The location capability of the location information at the access point 14 is forwarded. Therefore, the station 12 can anticipate 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. 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 requesting program or the presence advertisement program, which is defined in the IEEE 802.1 lv system 歹ij 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 Prior to the request, the own data known to the station 12 is forwarded to the access point 14. Therefore, since the access point 14 foresees the location data of the station 12, the access point 14 provides the capability and the station. 12 harmonize the presence service, 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. 18 C S ) 1356647

The station 12 is calculated or preserved for its own change. For example, the station 12 can receive the calculated position from the access point: or the probe response message. The station 12 can be counted by the location information of the access point 14, wherein the location of the access point 14 The information is collected from the name. In other words, the station 12 can be set 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 a piano 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-frequency dual mode) capable of both WCDMA or a WLAN in which the interworking works, the platform 1 2 can receive its own location information or location data from the station. Conversely, the access point 14 may also associate or forward its own location data. The station 12 can maintain the I; set information. For example, the station 1 2 calculates its own bit by the access point full position information as described above. The presence parameter information element is added to the associated 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 location information of the station 12 in a wireless communication system can pass through the beacon. Similarly, the station calculates its own location F.

The address of the meridian is shown in Box 9, address RFC RFC hand (bit [Table 10] Format Description 0 CIVIC 1 GEO 2 CIVIC and GEO 3 Vendor Specific 4-1 5 Retention 27 1356647 Table 10 "GEO" and " The CIVIC" format is equivalent to that explained in Table 9. The location description values for the "CIVIC and GEO" format indicate that the station 12 or 14 is capable of supporting both "CIVIC" and "GEO" formats. The value of the position descriptor (bits 4 - 7) is as shown in Table 11. [Table 1 1] Format Description 0 CIVIC 1 GEO 2 CIVIC Priority 3 GEO Priority 4 Not Supported 5 Vendor Specific 6-15 Reserved

The “GEO” and “CIVIC” formats in Table 11 are equivalent to those explained in Table 9. The location description values for the "CIVIC Priority" and "GE0 Priority" formats indicate that the station 12 or 14 is capable of supporting both the "CIVIC" and "GEO" formats, but prefers the format specified. The location description value of the "unsupported" format indicates that the station 12 or 14 cannot support the "CIVIC" or "GEO" format. Adding "CIVIC Priority" and "GEO Priority" to the location descriptor block provides a number of types of location services for the station 12 or 14 to increase the quality of the presence service. 28 1356647

Therefore, the station 12 performs a presence in 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, and the II parameter information includes supporting geographic information. Location descriptor information for both the coordinate value CGEO') and the city location ('CIVIC'); and an execution component for performing the presence operation in a wireless communication system. In another aspect, the access point 14 operates in an access point of an access point in a wireless communication system. The access point 14 includes a receiving component for receiving data to another station in the wireless communication system, including presence parameter information, the presence parameter information including supporting geographic J ('GEO') and city location values ('CIVIC) ') The location descriptor of both and a receiving component for performing a function in a wireless communication system. The means for executing the program associated with the presence of the service can be implemented by means of software, hardware or a combination thereof in the access point 14. Similarly, the location descriptor information can be directed to the location information indicating a preference between the GEO and the CIVIC. The location descriptor included in the associated (or re-associated) request or response message (not present in the parameter information element is not limited to ^1, but may be mutable. For example, the location descriptor Only one of 4 and "CIVIC" can be defined.

The location resolution descriptor field has two fields indicating the location resolution (0-3 bits) and the I (4 bits) requested or sent in 4, as in Table 12 and Table 13. Instructions.

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 block is variable.

The position is accurately estimated as an estimate of the increment by 0.1 meter, defined by an unsigned integer of a low order data order (1 i 111 e e n d i a η) of 16 bits. For example, an accurate measurement of +/- 5 units of measurement is represented by the number 0 X 3 2 (decimal point 50). If the position is accurately estimated to be unknown, the block is set to zero. The location value block contains the location information that 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 〇 (UTC). 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.

Or the parameter information subcomponent may contain options or vendor specific information as described in Figure 7 and Table 4. If the frame for initializing the service is a unicast presence group, then the peer STA should respond to a presence configuration request frame request message frame including a presence status sub-component indicating the success. The presence state sub-element has four possible status values: defeat, rejection, and incapability. When a S T A receives a configuration response frame with a presence; j indicates any state other than success, j should assume that the original request has not been made and that S should take appropriate action based on the state value. The original request may be retried or an alternate request sent for the presence status "Failed". For "incapable", the STA shall not send another configuration request that is associated with the previous B S S. t station 12 purpose, can respond to or save the location data information sub-indicator parameters and sub-components, the existence of the existence of the request message, the existence of the request is successful, lost state (which refers to I丨J the STA backhaul The STA presence status configuration request 34 1356647 The requesting station can use the station block of the location service information sub-element in Figure 9 and Table 6 to start or stop the service. Supporting the presence of the station 12 or 14 may send a presence configuration request frame to provide its own location information and location capabilities.
