Description

接入点的发现方法、 装置及系统  Access point discovery method, device and system
技术领域 本发明涉及无线通信技术领域, 具体涉及一种接入点的发现方法、 装 置及系统。 The present invention relates to the field of wireless communication technologies, and in particular, to a method, device, and system for discovering an access point.
背景技术 无线局 i或网 (wireless local area network, WLAN )是一种以无线方式 组建的网络体系, 支持接入 WLAN的用户设备 ( user equipment, UE )通 过搜索并连接到 WLAN的接入点 (access point, AP ), 就可以享受到便捷 的宽带互联网服务。 近年来, 随着移动数据流量的大幅上升, 移动通信网 络的带宽和速度都面临着越来越大的挑战, 电信运营商开始部署大量的 AP 供 UE接入, 以緩解现有移动通信网络的数据流量负荷。 BACKGROUND A wireless local area network (WLAN) is a wirelessly established network system that supports user equipment (UE) accessing a WLAN by searching and connecting to an access point of a WLAN ( Access point, AP ), you can enjoy convenient broadband Internet service. In recent years, with the sharp increase of mobile data traffic, the bandwidth and speed of mobile communication networks are facing more and more challenges. Telecom operators are beginning to deploy a large number of APs for UE access to alleviate the existing mobile communication networks. Data traffic load.
目前, 支持接入 WLAN的 UE可以通过 WLAN搜索,发现周围可用的 AP。 但是当 UE不在 AP的覆盖范围时, 持续进行 WLAN搜索会耗费 UE 较多电量。 为了节省电量, 通常 UE并不会一直进行 WLAN搜索。 这就导 致即使 UE进入 AP的覆盖范围, UE也不会发现周围可用的 AP。  Currently, UEs that support access to the WLAN can search for available APs through WLAN search. However, when the UE is not in the coverage of the AP, continuing the WLAN search will consume more power of the UE. In order to save power, the UE does not always perform a WLAN search. This results in the UE not discovering the surrounding APs even if the UE enters the coverage of the AP.
现有技术中,可以由移动通信网络辅助 UE发现周围可用的 AP。例如, 在基于蜂窝小区标识符( cell identifier )的 WLAN发现方法中, 当 UE进入 预先铺设有 AP的蜂窝小区时,蜂窝网设备可以指示 UE搜索周围可用 AP。 但是, 由于蜂窝小区的覆盖范围通常远大于 AP的覆盖范围, 当 UE进入铺 设有 AP的蜂窝小区时,仍然不能确定 UE是否位于 AP的覆盖范围。此时, 若指示 UE进行 WLAN搜索, 仍然很有可能搜索不到可用 AP, 既浪费了 UE电量, 也降低了用户的使用体验。 发明内容 本发明实施例提供了一种接入点的发现方法、 装置及系统, 可以确定 用户设备是否位于所述接入点的覆盖范围。 In the prior art, the UE can be assisted by the mobile communication network to discover surrounding APs. For example, in a cell identifier based WLAN discovery method, when a UE enters a cell in which an AP is pre-paved, the cellular network device may instruct the UE to search for surrounding available APs. However, since the coverage of the cell is usually much larger than the coverage of the AP, when the UE enters the cell where the AP is deployed, it is still not determined whether the UE is located in the coverage of the AP. At this time, if the UE is instructed to perform WLAN search, it is still possible to search for an available AP, which wastes the power of the UE and reduces the user experience. SUMMARY OF THE INVENTION Embodiments of the present invention provide a method, an apparatus, and a system for discovering an access point, which can determine whether a user equipment is located in a coverage range of the access point.

其中, 所述预设门限, 可以是第一测量结果与参考测量结果的最大可 接受差值, 可以根据经验值预先设定。 可以理解, 所述预设门限的取值越 小, 即要求所述第一测量结果与参考测量结果的取值越接近, 所述确定第 一 UE位于所述 AP的覆盖范围的准确性就越高, 即误 ·^艮率也越低。 所述误 报率, 是指所述第一 UE实际地理位置不在所述 AP的覆盖范围, 但被错误 确定在所述 AP的覆盖范围的概率。 理想情况下, 希望误报率越低越好, 但 在实践中, 若仅通过减小预设门限的取值来降低误报率, 当误报率降低到 一定程度时, 再减小预设门限的取值, 误报率会趋于稳定, 但是漏报率会 明显上升。 所述漏报率, 是指所述第一 UE实际地理位置在所述 AP的覆盖 范围, 但未被确定在所述 AP的覆盖范围的概率。 因此, 所述预设门限的取 值并非越小越好, 在实际应用中, 所述预设门限的取值可根据误报率和漏 报率的要求进行权衡。 The preset threshold may be the maximum of the first measurement result and the reference measurement result. Accept the difference, which can be preset according to the empirical value. It can be understood that the smaller the value of the preset threshold is, that is, the closer the value of the first measurement result is to the reference measurement result, the more accurate the determining that the first UE is located in the coverage area of the AP High, that is, the lower the error rate. The false alarm rate refers to the probability that the actual geographic location of the first UE is not in the coverage of the AP, but is incorrectly determined in the coverage of the AP. Ideally, the lower the false positive rate, the better, but in practice, if you only reduce the false alarm rate by reducing the value of the preset threshold, when the false alarm rate is reduced to a certain level, the preset is reduced. The value of the threshold, the false positive rate will tend to be stable, but the false negative rate will increase significantly. The false negative rate refers to a probability that the actual geographic location of the first UE is in the coverage of the AP, but is not determined to be in the coverage of the AP. Therefore, the value of the preset threshold is not as small as possible. In practical applications, the value of the preset threshold may be weighed according to the requirements of the false alarm rate and the false negative rate.

The difference between the measured values of each of the cells is compared with the single preset threshold; if the difference between the measured values of each of the cells is less than or equal to the single preset The threshold is determined to determine that the first UE is located in a coverage area of the AP.
情形三、 所述预设门限为针对多个小区设置的单一预设门限: 分别计算所述第一测量结果的全部小区或部分小区中每个小区的测量 值与所述参考测量结果中相同小区的测量值的差值; 对上述每个小区的测 量值的差值进行统计处理, 得到所述第一测量结果与所述参考测量结果的 差值统计量; 若该差值统计小于或等于该单一预设门限, 则确定所述第一 Scenario 3: The preset threshold is a single preset threshold set for multiple cells: respectively, calculating a measurement value of each cell in all cells or partial cells of the first measurement result and the same cell in the reference measurement result The difference between the measured values of each of the cells is statistically processed to obtain a difference statistic between the first measurement result and the reference measurement result; if the difference statistic is less than or equal to the a single preset threshold, determining the first

采用图 1所示实施例提供的接入点的发现方法,可以根据对移动通信网 络中小区测量的结果, 即 AP的参考测量结果和第一 UE的第一测量结果, 无需额外获取第一 UE和 AP的地理位置信息, 即可便捷地确定所述第一 UE是否位于所述 AP 的覆盖范围, 从而克服了基于蜂窝网小区标识符的 WLAN发现方法不能确定 UE是否在 AP的覆盖范围的缺陷。 可选地,在本实施例中, 可以根据所述 AP的信号路径损耗确定所述预 设门限; 或者, 也可以根据第二 UE的第二测量结果与所述 AP的参考测量 结果的差值确定所述预设门限, 所述第二 UE为已成功搜索或连接到所述 AP的 UE。  The method for discovering the access point provided by the embodiment shown in FIG. 1 may be based on the result of cell measurement in the mobile communication network, that is, the reference measurement result of the AP and the first measurement result of the first UE, without additionally acquiring the first UE. And the geographical location information of the AP, which can conveniently determine whether the first UE is located in the coverage of the AP, thereby overcoming the defect that the WLAN discovery method based on the cellular network cell identifier cannot determine whether the UE is in the coverage of the AP. . Optionally, in the embodiment, the preset threshold is determined according to a signal path loss of the AP; or, may be, according to a difference between a second measurement result of the second UE and a reference measurement result of the AP.

所述 AP的信号路径损耗是指 AP信号的传输路径对信号功率的衰减。 在同等条件下, 传输路径越长, 信号路径损耗也就越大, 若信号路径损耗 超过最大路径损耗, UE接收到 AP信号的接收信号功率会低于 UE的接收 机灵敏度, 此时 UE就不能搜索到或连接到该 AP。 因此, 根据 AP信号的 最大路径损耗能够确定 AP的覆盖范围。 实际应用中, 可以根据 AP的信号 发射功率以及 UE的接收机灵敏度计算得到最大路径损耗,所述 AP的信号 发射功率以及 UE的接收机灵敏度可以预先确定。此外,考虑到所述移动通 信网络与所述 WLAN为不同制式的无线网络, 两者的工作频率可能不同。 此后, 还可以根据 AP信号的最大路径损耗, 以及移动通信网络与所述 AP 的信号频率,计算出在该 AP的覆盖范围,移动通信网络信号的最大路径损 耗。例如,可以利用如下公式进行计算,The signal path loss of the AP refers to the attenuation of the signal power by the transmission path of the AP signal. Under the same conditions, the longer the transmission path, the greater the signal path loss. If the signal path loss exceeds the maximum path loss, the received signal power of the UE receiving the AP signal will be lower than the receiver sensitivity of the UE. Searched or connected to the AP. Therefore, the coverage of the AP can be determined based on the maximum path loss of the AP signal. In practical applications, can be obtained according to the maximum path loss AP signal transmit power and receiver sensitivity of the calculation of the UE, the AP transmit power and receiver sensitivity signal UE may be determined in advance. In addition, considering that the mobile communication network and the WLAN are different types of wireless networks, the operating frequencies of the two may be different. Thereafter, the maximum path loss of the mobile communication network signal can be calculated according to the maximum path loss of the AP signal and the signal frequency of the mobile communication network and the AP. For example, you can use the following formula to calculate,

The maximum path loss of the mobile communication network signal is the maximum acceptable difference between the reference measurement result and the first measurement result, and the maximum acceptable difference value may be used as the preset threshold The value.
