[0037] 步骤S100,获取终端上报的终端位置信息,查询关联数据库获取各WLAN热点的热点位置信息,根据所述终端位置信息和各所述WLAN热点的热点位置信息,计算所述终端与各所述WLAN热点之间的距离最小值; [0037] step S100, the acquired terminal location information reported by the terminal, the database associated with the query obtain position information of each hotspot WLAN hot spots, the hot spot according to the position information of the terminal and the location information of each of the WLAN hotspots, calculating each of the terminal and the the distance between said minimum WLAN hotspot;

[0038] 步骤S102,判断所述距离最小值是否小于预设距离门限值,若小于所述预设距离门限值则进入步骤S104; [0038] step S102, determining whether the minimum distance is less than a predetermined distance threshold, if the distance is less than the preset threshold the process proceeds to step S104;

[0039] 步骤S104,判断所述距离最小值对应的WLAN热点的策略状态是否为允许所述终端接入,若所述WLAN热点的策略状态为允许所述终端接入,则进入步骤S106 ; [0039] In step S104, it is determined whether the WLAN hot spots corresponding to the minimum distance policy state to allow the access terminal, if the WLAN hotspot policy state to allow the terminal to access, the process proceeds to step S106;

[0040] 步骤S106,下发切换策略信息至所述终端。 [0040] step S106, the switching circuit of the policy information to the terminal.

[0041] 具体地,蜂窝网络和WLAN间的无缝切换装置中包含关联数据库,关联数据库中存储全网的WLAN热点的热点位置信息,热点位置信息为标示WLAN热点地理位置的信息。 [0041] In particular, seamless switching device between a cellular network and the WLAN association database contains, stored in the database associated with the entire network of the WLAN hotspot hotspot location information and hotspot location information of the location designation information WLAN hotspots. 终端上报终端位置信息至该装置,终端位置信息为标示终端所在地理位置的信息。 Terminal to report the location information to the terminal apparatus, location information of the terminal position information of the labeled terminal is located. 该装置获取终端上报的终端位置信息后,开启蜂窝网络和WLAN间的无缝切换操作,具体包括: After the device acquires the terminal location information reported by the terminal, opening the seamless switching operation between a cellular network and a WLAN, including:

[0042] 查询关联数据库,获取各WLAN热点的热点位置信息,根据终端位置信息和各WLAN热点的热点位置信息,计算该终端与各WLAN热点之间的距离,反馈距离最小值,然后判断该距离最小值是否小于预设距离门限值。 [0042] associated database query, acquires position information of each hotspot WLAN hot spots, the hot spot according to the location information and the terminal location information of each WLAN hotspots, calculates the distance between each terminal and the WLAN hot spots, the feedback from the minimum value, and then determines whether the distance the minimum distance is less than the preset threshold. 由于终端和WLAN热点之间进行通信的过程中,信号强度会随着距离的增加而加速衰减,因此当终端和WLAN热点之间的距离过大时,终端与WLAN热点之间无法进行正常通信。 Since the process between the terminal and the WLAN hotspot communication, signal strength with increasing distance attenuation is accelerated, so that when the distance between the terminal and the WLAN hotspot is too large for normal communication between the terminal and the WLAN hotspot. 距离最小值小于预设距离门限值表示终端周围存在可正常通信的WLAN热点。 The minimum distance is less than the predetermined distance threshold may indicate the presence of the WLAN hotspot surrounding normal communication terminal.

[0043] 在优选的实施例中,预设距离门限值为100米。 [0043] In a preferred embodiment, the predetermined distance threshold is 100 meters.

[0044] 当WLAN热点处于重负载时,终端再接入WLAN热点后进一步加重该WLAN热点的负载,容易造成终端通信不畅,掉话等情况。 [0044] When the WLAN hotspot in a heavy load, the terminal to access the WLAN hotspot and then further increases the load of the WLAN hotspots, where the terminal is likely to cause poor communication, such as call drop. 网络侧系统根据WLAN网络中WLAN热点的负载情况,实时更新WLAN热点的策略状态,当某一个WLAN热点的负载超过预设值时,即将该WLAN热点的策略状态更改为不允许新的终端接入。 The system according to the load-side network WLAN network WLAN hotspots, updated in real time policy status WLAN hotspots, when a load of a WLAN hot spot exceeds a preset value, i.e. the WLAN hotspots change the status of the policy does not allow access to the new terminal .

[0045] 因此当终端周围存在距离较近的WLAN热点时,需要进一步判断距离该终端最近的WLAN热点的策略状态是否为允许所述终端接入,若允许则下发切换策略信息至终端,切换策略信息包括距离最小值对应的WLAN热点的WLAN热点信息,如热点ID。 [0045] When present, the WLAN hotspot close distance around a terminal, needs to be further determined whether the nearest WLAN hotspot policy state of the terminal to allow the access terminal, if allowed to send the next handover policy information to the terminal, the switching WLAN hotspot information comprising policy information corresponding to the minimum distance WLAN hotspots, such as hot spot ID. 终端根据切换策略信息,开启WLAN搜索,接入距离该终端最近的WLAN热点,完成蜂窝网到WLAN网络的切换。 The handover policy information terminal, WLAN search open access WLAN hotspots closest to the terminal, the handover is completed cellular network WLAN.

[0046] 本实施例的技术方案中,蜂窝网络和WLAN间的无缝切换装置通过获取终端的终端位置信息,查询关联数据库获取全网WLAN热点的热点位置信息,根据终端位置信息和热点位置信息判断距离终端最近的WLAN热点是否在预设距离门限值的范围内,若是则进一步判断距离终端最近的WLAN热点是否允许终端接入,如果允许则下发切换策略信息至该终端,通知该终端开启WLAN搜索,接入该WLAN热点。 Technical Solution [0046] In the present embodiment, seamless handover between the cellular network and means acquires WLAN hotspot WLAN hotspot location information of the whole network by acquiring location information of the terminal end, database query related, location information based on the terminal location information and hotspot WLAN hotspots in the last terminal determines whether a preset distance from the threshold range, if it is further determined from the latest WLAN hotspots terminal is allowed access to the terminal, if it is allowed to send the policy information to the switching terminal to notify the terminal open WLAN search, the access of the WLAN hotspot. 实现了网络侧进行智能判断,制定切换策略信息通知终端接入WLAN热点,从而提高了WLAN网络的利用率,降低了蜂窝网络的负载压力,进一步地,由于切换策略信息是由网络侧制定,因此无需终端侧的用户进行繁琐的切换设置,简化了用户操作。 Implement intelligent network side is determined, the terminal information notification policy to develop switching access the WLAN hotspot, thereby improving the utilization of WLAN network, reducing the load pressure of a cellular network, and further, since the switching policy information developed by the network side, so the user terminal side without cumbersome switch setting, simplifying user operation.

[0048] 通过后台短信通道下发切换策略信息,既不需要更改现有信令通道的传输协议,又不会使用户产生GPRS流量费用。 [0048] The message sent by switching a background channel policy information, neither change the existing transport protocol signaling path, the user will not GPRS traffic charges.

[0049] 图2为本发明蜂窝网络和WLAN间的无缝切换方法第二实施例的流程图,如图2所示,本实施例由网络侧的蜂窝网络和WLAN间的无缝切换装置执行,该方法包括: [0049] FIG seamless handover method between a cellular network and a WLAN flowchart of a second embodiment of the present invention, shown in Figure 2, for example, performed by means seamless handover between a cellular network and a WLAN network according to the present embodiment , the method comprising:

[0056] 具体地,蜂窝网络和WLAN间的无缝切换装置获取到终端上报的终端位置信息后,首先判断终端所处的蜂窝网小区的小区负载是否大于预设小区负载门限值,若小于预设小区负载门限值则说明该终端目前所处的蜂窝网小区负载较轻,无需切换至WLAN网络,若大于预设小区负载门限值则说明该终端目前所处的蜂窝网小区负载较重,需要切换至WLAN网络。 [0056] In particular, seamless switching means between the cellular and WLAN network after obtaining the terminal location information reported by the terminal, the terminal first determines the cell in which the cellular network cell is the cell load is greater than a preset load threshold, if less than load cell preset threshold indicates that the terminal is currently located in the cellular network cell is lightly loaded, without switching to the WLAN network, if greater than the preset threshold then the load cell of the cellular network terminal is currently located more load cells weight, need to switch to WLAN network.

[0057] 当蜂窝网小区的负载较重时,该装置启动蜂窝网络和WLAN间的无缝切换操作,具体切换操作与第一实施例中相应步骤相同。 [0057] When the load cell of the cellular network is heavy, the switching means to enable seamless operation between the cellular network and WLAN, the concrete switching operation of the first embodiment the same as the corresponding step.

[0058] 本实施例的技术方案中,蜂窝网络和WLAN间的无缝切换装置获取终端的终端位置信息后,首先判断终端所在的蜂窝网小区是否处于重负载,若是则启动切换操作,将该终端从负载较重的蜂窝网小区切换至负载较轻的WLAN网络中。 [0058] The technical solutions of the present embodiment, the seamless handover between the cellular device and the WLAN network after acquiring terminal position information of the terminal, the terminal first determines whether the cell where the cellular network is in a heavy load, if the switching operation is initiated, the terminal from a heavy load to the load cell of the cellular network lighter WLAN network. 从而实现了网络侧进行智能判断,制定切换策略信息通知终端接入WLAN热点,提高了WLAN网络的利用率,降低了蜂窝网络的负载压力,进一步地,由于切换策略信息是由网络侧制定,因此无需终端侧的用户进行繁琐的切换设置,简化了用户操作。 Enabling the intelligent network side is determined, to develop the utilization of the access terminal information notification policy handover WLAN hot spots, improved WLAN network, a cellular network load pressure is reduced, and further, since the switching policy information are made by the network side, so the user terminal side without cumbersome switch setting, simplifying user operation.

[0070] 本实施例的技术方案中,蜂窝网络和WLAN间的无缝切换装置通过获取终端的终端经纬度信息,根据终端经纬度信息和热点经纬度判断终端周围是否有允许其接入的WLAN热点,制定切换策略信息。 [0070] This technical solution of the embodiment, a seamless handover between the cellular network and means WLAN terminal by acquiring latitude and longitude information of the terminal, the terminal according to latitude and longitude information and latitude hotspots around the terminal determines whether there is allowed to access WLAN hotspots, formulated switching policy information. 由此实现通过网络侧进行智能判断,制定切换策略信息通知终端接入WLAN热点,提高了WLAN网络的利用率,降低了蜂窝网络的负载压力,由于切换策略信息是由网络侧制定,因此无需终端侧的用户进行繁琐的切换设置,简化了用户操作。 Analyzing thus achieved through intelligent network, the terminal information notification policy to develop switching access the WLAN hotspot, improve the utilization of WLAN network, reducing the load pressure of a cellular network, since the switching policy information are made by the network side, there is no need terminal cumbersome user side switch setting, simplifying user operation. 进一步地,由于GPS模块上报的终端经纬度信息精准度高,因此网络侧能够根据终端经纬度准确寻找到终端周围的WLAN热点,提高了终端切换的成功率。 Further, due to the high module GPS latitude and longitude information reported by the terminal accuracy, so the network side can accurately find the WLAN hotspot terminal according to latitude and longitude around the terminal, the terminal improves the success rate of handover.

[0072] 通过后台短信通道下发切换策略信息,既不需要更改现有信令通道的传输协议,又不会使用户产生GPRS流量费用。 [0072] The message sent by switching a background channel policy information, neither change the existing transport protocol signaling path, the user will not GPRS traffic charges.

[0073] 进一步地,终端位置信息还包括所述终端所在蜂窝网小区的小区ID,所述关联数据库中还包括各蜂窝网小区的小区ID以及小区经纬度信息,该方法步骤S304之前还包括: [0073] Furthermore, the terminal position information further includes a cell ID of the cell of a cellular network terminal is located, the association database further comprises a cell ID and the latitude and longitude information of each cell in the cellular network cells, the method further comprising before step S304:

[0074] 步骤S312,判断所述终端经纬度信息是否无效,若所述终端经纬度信息无效,则进入步骤S314,若所述终端经纬度信息有效,则进入步骤S304 ; [0074] step S312, the terminal determines the latitude and longitude information is invalid, if the terminal is not valid latitude and longitude information, the process proceeds to step S314, the terminal if the latitude and longitude information is valid, the process proceeds to step S304,;

[0077] 具体地,终端上报终端位置信息至蜂窝网络和WLAN间的无缝切换装置,其中终端位置信息包括终端经纬度信息和终端所在蜂窝网小区的小区ID。 [0077] Specifically, the terminal position information sent to the terminal apparatus to the cellular switch seamlessly between networks and WLAN, wherein the terminal position information includes the latitude and longitude information of a cell ID of the terminal and the terminal is located in the cellular network cells. 该装置首先判断终端经纬度信息是否有效,当终端没有GPS模块或终端位于无GPS信号区域时,上报的终端位置信息中终端经纬度信息无效。 The terminal apparatus first determines whether a valid latitude and longitude information, GPS module or when the terminal is not located in the terminal areas when no GPS signal, the terminal reported by the terminal position information is latitude and longitude information is invalid. 当终端经纬度信息无效时,根据终端上报的小区ID来判断终端所在的地理位置。 When the terminal is not valid latitude and longitude information, the cell ID reported by the terminal to determine the location of the terminal is located.

[0078] 根据小区ID查询关联数据库,关联数据库中包括各WLAN热点的热点经纬度、各蜂窝网小区的小区ID以及小区经纬度信息,获取终端所在小区的小区经纬度信息。 [0078] The database query associated with the cell ID, latitude and longitude association database comprises for each hotspot WLAN hotspots, cell ID, and latitude and longitude information of each cell in the cellular network cells, obtaining a cell latitude and longitude information of the cell terminal is located. 根据小区经纬度信息和各WLAN热点的热点经纬度,计算出终端所在的蜂窝网小区和各WLAN热点之间的距离,并反馈距离最小值。 The hot spot cell latitude and longitude information and latitude and longitude of each WLAN hotspots, calculates the distance between the cellular terminal is located in each cell and a WLAN hot spots, and the feedback from the minimum value. 当终端位置信息中的终端经纬度信息有效时,则优先选择根据终端经纬度信息和各WLAN热点的热点经纬度来计算终端和各WLAN热点之间的距离。 When the terminal in the terminal position information of latitude and longitude information is valid, the preference calculates the distance between each terminal and the WLAN hotspot hotspot according to latitude and longitude and the latitude and longitude information of each terminal WLAN hotspots.

[0079] 由于GPS模块上报的终端经纬度信息精确度很高,因此当终端上报的经纬度信息有效时,优先根据终端经纬度信息来确定终端的位置。 [0079] Since the GPS latitude and longitude information of a terminal module reports a high degree of accuracy, so that when the valid latitude and longitude information reported by the terminal, the terminal priority determining a location based on latitude and longitude information terminal. 但部分终端上没有GPS模块,或当终端进入无GPS信号的区域时,存在终端无法上报终端所在地的经纬度的情况。 GPS module but no part of the terminal, when the terminal enters the area or no GPS signal, the presence of the terminal when the terminal can not report a latitude and longitude location. 因此当终端上报的终端经纬度信息无效时,以小区经纬度补充确定终端的位置,从而实现了在终端通过GPS定位失败时还可以通过其他方式获得可用的终端位置信息。 Therefore, when the latitude and longitude information reported by the terminal the terminal is invalid, to supplement the cell latitude and longitude of the position determination terminal, thereby realizing the GPS positioning terminal can have failed obtained by the terminal location information available through other means.

[0088] 步骤S414,判断所述距离最小值对应的WLAN热点的策略状态是否为允许所述终端接入,若所述WLAN热点的策略状态为允许所述终端接入,则进入步骤S416,若所述WLAN热点的策略状态为不允许所述终端接入,则流程结束; [0088] step S414, the policy determines the state corresponding to the minimum distance WLAN hotspots whether to allow the access terminal, if the WLAN hotspot policy state to allow the terminal to access, the process proceeds to step S416, the if state of the WLAN hotspots policy to the terminal access is not allowed, the flow ends;

[0089] 步骤S416,下发切换策略信息至所述终端。 [0089] step S416, the policy information issued to the switching terminal.

[0090] 具体地,蜂窝网络和WLAN间的无缝切换装置中的热点状态数据库中存储全网WLAN热点的策略状态,该装置根据预设周期采集全网WLAN热点的参数信息,并根据WLAN热点的参数信息获得WLAN热点的策略状态,定时更新热点状态数据库中每个WLAN热点的策略状态,具体方法如下: [0090] In particular, seamless switching device between a cellular network and the WLAN hotspot state of the whole network stored in the database policy status WLAN hotspots, the device information acquisition parameters entire network WLAN hot spots according to a preset period, and according to the WLAN hotspot parameter information obtained WLAN hotspots state policy, the policy update the timing status of each hotspot WLAN hotspots state database, as follows:

[0091 ] 该装置与各WLAN AC通信连接,各WLAN AC根据预设的采集粒度采集接入WLAN热点的总用户数、接入WLAN热点的用户中正在使用业务的业务用户数以及业务类型,WLAN AC根据预设周期将上述参数发送至蜂窝网络和WLAN间的无缝切换装置,预设周期等于WLANAC的采集粒度。 [0091] The WLAN communication device is connected with each of the AC, each WLAN AC predetermined size acquisition collection total number of users accessing the WLAN hotspot, the hotspot WLAN user access service and service type the number of users are using the service, according to the WLAN the AC transmission according to a preset period of the parameters to seamless handover between the cellular network and means WLAN, WLANAC preset period equal size acquisition. 根据各业务类型所占网络资源的大小设定各业务类型的业务权重值,例如根据各业务类型所占的网络带宽或所需的承载速率来设定各业务类型的业务权重值。 Occupied by each service type according to the size of the set traffic weight value of each service type of network resources, such as traffic weight value is set for each service type according to the network bandwidth or the required rate for each bearer service type occupies.

[0092] 根据总用户数和WLAN热点的拟覆盖面积,计算用户密度,用户密度等于总用户数与拟覆盖面积的比值。 [0092] The intended number of users and the total coverage area of ​​WLAN hot spots, the user density is calculated, the user density is equal to the ratio of the total number of users with the intended coverage area. 根据业务用户数和总用户数,计算业务渗透率,业务渗透率等于业务用户数和总用户数的比值。 The number of users and the total number of service users, service penetration rate calculation, traffic permeability equal to the ratio of the total number of users and the number of service users. 根据业务权重值和接入WLAN热点的用户所使用的业务类型计算WLAN热点的总业务权重。 WLAN hotspots calculated according to the service type and the traffic weight value to access the WLAN hotspots used by the user weight of the total traffic.

[0093] 根据影响WLAN热点负载的因素预设三个门限值,包括预设密度门限值、预设渗透率门限值以及预设权重门限值。 [0093] The factors affecting the WLAN hotspot preset load threshold of three, including a preset threshold density, permeability preset threshold and the preset weight threshold. 对WLAN热点的上述参数和预设的三个门限值进行比较,从而确定该WLAN热点的策略状态,其中策略状态分为允许终端接入和不允许终端接入,进一步设置允许终端接入为1,不允许终端接入为O。 WLAN hotspots above parameters and the preset three threshold values ​​are compared to determine the state of the WLAN hotspots policy, wherein the policy state is divided into the terminal is allowed access and allowed access terminal, the access terminal is further provided to allow 1, the access terminal is not allowed is O. 具体判断方法如下: Specific determination method is as follows:

[0094] 判断用户密度是否大于预设密度门限值,若不大于预设密度门限值则说明该WLAN热点接入的用户总数较少,因此将WLAN热点的策略状态设为允许所述终端接入;若大于预设密度门限值则说明该WLAN热点接入的用户总数较多。 [0094] determines whether the user density is greater than the predetermined density threshold, if not greater than the preset threshold then the density of the small total number of users of the WLAN hotspot access, so the policy is set to allow the state of the WLAN hotspots terminal access; density greater than the predetermined threshold value if the user of the WLAN hotspot access is described more total.

[0095] 进一步判断业务渗透率是否大于预设渗透率门限值,若不大于预设渗透率门限值,则说明该WLAN热点中正在使用业务的用户数量较少,因此将WLAN热点的策略状态设为允许所述终端接入;若大于预设渗透率门限值,则说明该WLAN热点中正在使用业务的用户 [0095] further determines whether the service is greater than a preset permeability permeability threshold, if not greater than the preset threshold permeability, then the small number of users of the WLAN hotspot service being used, so the strategy WLAN hotspots state allowing the terminal to access; permeability if it exceeds a preset threshold, it indicates that the WLAN hotspot service user is using

数量较多。 Larger quantities.

[0096] 进一步判断总业务权重是否大于预设权重门限值,若不大于预设权重门限值则说明该WLAN热点中虽然使用业务的用户数较多,但该用户所使用的业务需要的网络资源较小,因此将WLAN热点的策略状态设为允许所述终端接入,若大于预设权重门限值则说明该WLAN热点使用业务的用户数较多,且所使用业务需要的网络资源较多,因此将WLAN热点的策略状态设为不允许所述终端接入。 [0096] further determines whether the total traffic weights greater than a preset threshold weight, if not greater than the preset threshold then the weights of the WLAN hotspots large number of users while using the service, but the service used by the user needs less network resources, the policy state thus set to allow the WLAN hotspot access terminal, if the threshold value is greater than a predetermined weight then the weight of the WLAN hotspot large number of users use the service, and the service used by the network resources required more, so the policy is defined as the state of the WLAN hot spots do not allow the access terminal.

[0097] 在优选的实施例中,当用户密度大于预设密度门限值且业务渗透率大于预设渗透率门限值时,周期性计算该WLAN热点的总业务权重,如果连续三次出现总业务权重大于预设权重门限值,则将该WLAN热点的策略状态设为不允许所述终端接入。 [0097] In a preferred embodiment, when the user density is greater than a predetermined threshold density and penetration rate greater than a predetermined threshold value permeability periodically calculating the total traffic of the WLAN hotspot weight, if there is three times the total operational weight is greater than a predetermined weight threshold, the policy is set to the state of the WLAN hotspots terminal access is not allowed.

[0098] 蜂窝网络和WLAN间的无缝切换装置的热点状态数据库中存储全网WLAN热点的策略状态,并定时更新每个WLAN热点的策略状态。 [0098] Database seamless hot state switching device between a cellular network and a WLAN in the state of the whole network storage policy WLAN hotspots, and regularly updated for each policy state WLAN hotspots. 当终端上报终端位置信息至该装置后,该装置经过计算获得距离终端最近的WLAN热点后,查询热点状态数据库中该WLAN热点的策略状态,并判断该WLAN热点的策略状态是否为运行终端接入,若是则下发切换策略信息至终端。 When the terminal reports whether the location information to the terminal apparatus that has been calculated from the nearest hotspot WLAN terminal, queries the policy database state hot state of the WLAN hot spots, and determines the status of the WLAN hotspot access policy for the terminal to run , if the policy information issued to the switching terminal. 其中步骤S410至步骤S416和上述实施例中相应步骤的流程相同。 Wherein the same as step S410 to step S416 and the above-described embodiments, the flow of respective steps. [0099] 本实施例的技术方案中,蜂窝网络和WLAN间的无缝切换装置通过获取终端的终端经纬度信息,根据终端经纬度信息和热点经纬度判断终端周围是否有允许其接入的WLAN热点,并进一步制定切换策略信息。 [0099] This technical solution of the embodiment, a seamless handover between the cellular network and means WLAN terminal by acquiring latitude and longitude information of the terminal, the terminal according to latitude and longitude information and latitude hotspots around the terminal determines whether there is allowed to access WLAN hotspots, and switching to further develop policy information. 由此实现通过网络侧进行智能判断,制定切换策略信息通知终端接入WLAN热点,提高了WLAN网络的利用率,降低了蜂窝网络的负载压力,由于切换策略信息是由网络侧制定,因此无需终端侧的用户进行繁琐的切换设置,简化了用户操作。 Analyzing thus achieved through intelligent network, the terminal information notification policy to develop switching access the WLAN hotspot, improve the utilization of WLAN network, reducing the load pressure of a cellular network, since the switching policy information are made by the network side, there is no need terminal cumbersome user side switch setting, simplifying user operation. 进一步地,由于GPS模块上报的终端经纬度信息精准度高,因此网络侧能够根据终端经纬度准确寻找到终端周围的WLAN热点,提高了终端切换的成功率。 Further, due to the high module GPS latitude and longitude information reported by the terminal accuracy, so the network side can accurately find the WLAN hotspot terminal according to latitude and longitude around the terminal, the terminal improves the success rate of handover.

[0100] 进一步地,步骤S414后还包括: [0100] Further, the step S414 further comprises:

[0101] 若WLAN热点的策略状态为不允许所述终端接入,则进入步骤S418 ; [0101] When the policy is the state of the WLAN hotspots terminal access is not allowed, the process proceeds to step S418;

[0102] 步骤S418,判断与终端距离小于预设距离门限值的其他WLAN热点的策略状态是否为允许所述终端接入,若其他WLAN热点的策略状态为允许所述终端接入,则进入步骤S416,若其他WLAN热点的策略状态为不允许所述终端接入,则流程结束。 If [0102] Step S418, and the determined distance is less than other terminal WLAN hotspot predetermined distance threshold state policy to allow the access terminal, if the WLAN hotspots other policy state to allow the terminal to access, the process proceeds step S416, the policy state if said WLAN hotspots other terminal access is not allowed, the flow ends.

[0103] 具体地,当距离终端最近的WLAN热点的策略状态为不允许终端接入时,说明该WLAN热点处于重负载,对该WLAN热点临近的其他WLAN热点的策略状态进行判断,如果其他WLAN热点的策略状态为允许终端接入,临近的其他WLAN热点处于轻负载,下发切换策略信息至终端,通知终端接入临近的其他WLAN热点。 [0103] Specifically, when the latest state of the policy from the terminal is a WLAN hot spot does not allow the access terminal, indicating that the WLAN hotspot is a heavy load, the determination of the status of the other policy WLAN hotspot WLAN hotspots adjacent, if another WLAN policy hot state to allow access to the terminal, other neighboring WLAN hotspots at light load, the switching policy information issued to the terminal, the access terminal notifies other WLAN hotspot approaching.

[0104] 当最近的WLAN热点处于重负载时,将新请求接入终端调度到临近的处于轻负载的其他WLAN热点,从而起到WLAN网络负载均衡的作用。 [0104] When the latest WLAN hotspots in a heavy load, the new request scheduling access terminals in a WLAN hotspot to another adjacent light load, and thus play a role in the WLAN load balancing.
