Description

  The wireless industry has developed machine-to-machine (M2M) communications or machine-linked technologies such as smart grids, wireless sensor networks and resource control and applications focused on maximizing vehicle and commodity tracking. There is increasing interest in Type Communication (MTC). M2M uses devices (sensors, meters, etc.) to capture events (temperature, inventory levels, etc.) and convert the captured events into meaningful information (eg items that need to be replenished) Relayed to (software program) via a network (wireless, wired or hybrid). MTC relies on devices that interact to generate data with little manual assistance in any case, but the data needs to be available for human use. The user interface and mechanism allows for an easy query or, in general terms, an intuitive experience and interaction. Today's communication networks, such as mobile operator networks, have been designed and constructed to meet the needs of human communication. At the same time, machine-to-machine (M2M) communication means available in the market today have emerged. However, such means are almost monolithic infrastructure that does not interoperate.

  Internet of Things (IoT), a computational concept in which physical objects are connected to the Internet and can identify themselves to other devices, is related to MTC. IoT services rely on locating and tracking connected objects. IoT refers to identifiable objects and their virtual representations in an Internet-like configuration. RFID (Radio-Frequency Identification) is often viewed as a prerequisite for enabling IoT to manage devices and inventory by computers. Radio frequency systems utilize transmission signals received by mobile devices in the network. Used in multiple estimation techniques such as signal strength of received signal, angle of arrival, time of flight (ToF), etc., and thereafter used by triangulation to calculate node position.

  An access point (AP) may periodically provide location reports to stations that currently have a connection with the AP. A component that connects to a wireless medium in a network is referred to as a station. The station is equipped with a wireless network interface controller (WNIC). Wireless stations belong to one of two categories: access points and clients. An access point (AP) is usually a router and a base station for a wireless network. They transmit and receive radio frequencies for wireless enabled devices to communicate. Wireless clients can be mobile devices such as laptops, personal digital assistants, IP phones and other smartphones, or stationary devices such as desktops and workstations equipped with wireless network interfaces.

  The reporting AP transmits the information as part of the location configuration information report. The location configuration information report includes location information of the reporting AP, such as latitude, longitude, and altitude information. For a ToF location, an initiator such as a station needs to know the location of each unassociated AP that responded in order to self-recognize its location after calculating the range of the responding AP. The IEEE 802.11 standard provides a way to query the AP with which the station is associated for the location of the AP. However, the number of times the protocol is executed to obtain the location of an unassociated AP is currently too large.

FIG. 1 illustrates an AP location query according to an embodiment. FIG. 2 shows an LCI request according to IEEE 802.11k. FIG. 3 shows an optional sub-element field according to an embodiment. FIG. 4 shows a flag represented by a bit in the length field used to indicate the station to be queried according to the embodiment. FIG. 5 shows an LCI report according to an example. FIG. 6 is a flowchart of a method for providing a query for location information of an access point (AP) in the vicinity of a reporting AP according to an embodiment. FIG. 7 shows a block diagram of an example machine that provides a query for location information of access points (A) in the vicinity of a reporting AP according to an embodiment.

  The following description and drawings describe specific embodiments sufficient to enable those skilled in the art to practice. Other embodiments may include constructive, logical, electrical processing and other changes. Parts and features of some embodiments may be included in or substituted for those of other embodiments. The following examples in the claims cover the available equivalents of the claims.

  The embodiments described herein provide an AP location query for access points (APs) in the vicinity of the reporting AP in order for the station to determine its location. For example, the AP may be configured in a cluster of APs, and some may be other than the reporting AP, and the AP may be in the vicinity of the reporting AP or the like. The 802.11k standard provides a Location Configuration Information Request (LCI Request) protocol that allows a station to obtain the location of a reporting AP. The reporting AP may be an associated AP, in which case the frame exchange may also be secured utilizing the Protected Management Frame facility. Other 802.11 standards such as the 802.11v standard and the 802.11u standard use similar LCI messages. According to an embodiment, the location of APs other than the reporting AP may be provided via enhancements and extensions of the 802.11k protocol. APs may be identified by their basic service set identifier (BSSID). BSSID is the MAC address of the radio interface or subinterface on which the access point hosts the SSID. Access points include BSSIDs in their beacons and probe responses.

  The reporting AP transmits the information as part of the location configuration information report. Location Configuration Information Report includes reporting AP location information such as latitude, longitude and altitude information. Enhancements and extensions to the 802.11k protocol provide power and time savings and secure location reporting. Make the medium possible.

FIG. 1 illustrates an AP location query 100 according to an embodiment. In FIG. 1, four APs are shown in the network, namely AP ₁ 110, AP ₂ 120, AP ₃ 130, and AP ₄ 140. A client 150 such as a UE or a mobile phone communicates with _four APs: AP ₁ 110, AP ₂ 120, AP ₃ 130, AP ₄ 140. The network management / gateway 160 manages network users such as APs, ie AP ₁ 110, AP ₂ 120, AP ₃ 130, AP ₄ 140, client 150 in the controlled network.

Fine timing measurement frame 170 allows the receiving station to accurately measure the round trip time (RTT) for the transmitting station. Periodic transmission of fine timing measurement frames 170 from one station to another allows the receiving station to track changes in RTT with respect to the transmitting station over time. In FIG. 1, the client may receive a fine timing measurement frame 170 from _four APs, namely AP ₁ 110, AP ₂ 120, AP ₃ 130, AP ₄ 140. In FIG. 1, AP ₁ 100 is the associated AP and handles location requests from client stations 110 for the location of neighboring APs, ie AP ₂ 120, AP ₃ 130, AP ₄ 140. Location request 180 is sent from the client to AP ₁ 110, which is the associated AP. AP ₁ 110, which is the associated AP, may not know the location of its neighbors. Accordingly, the network management / gateway 160 may be queried to obtain location information 190 of neighboring APs AP ₂ 120, AP ₃ 130, AP ₄ 140. The associated AP, AP ₁ 110, then provides a location report 180 that provides the location of AP ₁ , serving AP, along with the location of AP ₂ 120, AP ₃ 130, AP ₄ 140, neighboring APs, to client 150. May be sent to.

When the sub-element ID 310 has a value 314 of 1, an optional sub-element field 300 is utilized for the azimuth request 324, which has a value 334 in the length field 330 (in octets) 330 The possible field 340 is Yes344. Yes 344 in the expandable field 340 indicates that the length indicated in the sub-element length field 330 may be expanded. When the sub-element ID 310 has a value 318 of 221, an optional sub-element field 300 is utilized for the vendor specific query 328, which has a value 338 in the length field 330 (by octet) 330.

  One of the reserved sub-element IDs 311, 315, 319 may be used to query a nearby AP 340. The name 320 of the reserved sub-element ID 311, 315, 319 may be changed to the position of the neighboring AP 342. The length field (in octets) 330 may have a value 344 of 61, and the expandable field 340 may be signaled by a value of Yes 346. When the expandable field 340 at the location of the neighboring AP 342 is set to YES 346, the length 344 shown in the length field 330 may be expanded. The 61 octets 344 of the length field 330 represent 488 bits.

  FIG. 4 shows the flags represented by the bits in the length field 400 used to indicate the station 400 to be queried according to the embodiment. In FIG. 4, the flag includes a BSSID array field 410 (BSSID = 6 × UINT8, Max Length = 10), an AP list notification flag field 420, and a reserve field 430. BSSID array field 410 identifies the queried AP using 480 bits 412. The AP list notification flag field 420 is a 1-bit length 422 for indicating whether a list of APs is provided. The reserve field 430 is 7 bits long 432. When the request has a flag 420 to indicate a station query for a particular AP as indicated by the AP's BSSID array field 410, the request is originated. If there is no specific AP indicated in the BSSID array field 410, the AP to which the request is sent sends a report on neighboring APs according to its determination.

  FIG. 5 shows an LCI report 500 according to an embodiment. As shown in FIG. 5, the LCI report 500 includes latitude 510, longitude 520, and altitude 530 information. The length of each field, such as fields of latitude 510, longitude 520, and altitude 530, is indicated by a defined length. However, the defined length may be changed without departing from the scope of the embodiments.

  The optional sub-element 550 may have multiple frames for transmitting location information for each neighboring AP and may provide additional information such as ToF support, floor text, and the like. Thus, separate frames may be sent for each AP. The length of the optional sub-element is variable 522. The optional sub-element field 550 may have a sub-element ID that includes a reserved sub-element ID as shown in FIG. Therefore, the reserve sub-element ID may be used to report the position information of the neighboring AP.
