技术领域technical field
本发明涉及通信领域，尤其涉及一种接入网络选择装置和方法。The present invention relates to the communication field, in particular to a device and method for selecting an access network.
背景技术Background technique
随着用户需求的提高和网络技术的不断成熟，运营商在原有2G网络基础上，正积极部署3G网络和WLAN网络，后续还将引入LTE网络。由于上述几种网络具备不同的覆盖能力和业务场景，将长期共存。为了向用户提供更高的服务质量，带来更好的体验，如何进行接入网络的选择成了一个急需解决的问题。With the improvement of user demands and the continuous maturity of network technology, operators are actively deploying 3G networks and WLAN networks on the basis of the original 2G networks, and will introduce LTE networks in the future. Since the above-mentioned networks have different coverage capabilities and service scenarios, they will coexist for a long time. In order to provide users with higher quality of service and better experience, how to select an access network has become an urgent problem to be solved.
现有的接入网络选择方法可以分为两类，第一类是侧重于网络侧，例如，考虑各网络的信号强度、网络负荷、网络时延等；第二类是综合考虑网络侧和用户侧，例如，考虑用户接入的费用、网络的信号强度、网络时延等。其中，通过第二类方法选择接入网络时，因没有考虑通信对端的情况和/或用户签约优惠的信息，导致在考虑用户接入费用时，有所偏差，降低了用户的感受。The existing access network selection methods can be divided into two categories. The first category focuses on the network side, for example, considering the signal strength, network load, network delay, etc. of each network; the second category comprehensively considers the network side and user On the other hand, for example, consider the cost of user access, the signal strength of the network, and the network delay. Among them, when selecting an access network through the second method, because the situation of the communication peer and/or the information of the user's subscription discount are not considered, there is a deviation in the consideration of the user's access fee, which reduces the user's experience.

具体实施方式detailed description
为使本发明实施例要解决的技术问题、技术方案和优点更加清楚，下面将结合附图及具体实施例进行详细描述。In order to make the technical problems, technical solutions and advantages to be solved by the embodiments of the present invention clearer, the following will describe in detail with reference to the drawings and specific embodiments.
本发明实施例提供了一种接入网络选择装置，用于为支持多个通信网络的终端选择接入网络，如图1所示，所述接入网络选择装置包括：An embodiment of the present invention provides an access network selection device for selecting an access network for a terminal supporting multiple communication networks. As shown in FIG. 1 , the access network selection device includes:
接收模块，用于接收主叫终端发送的针对第一业务的业务请求信息；A receiving module, configured to receive service request information for the first service sent by the calling terminal;
第一获取模块，用于在收到所述业务请求后，获取所述多个通信网络中的每个通信网络的评估参数；每个网络对应的评估参数至少包括执行所述第一业务的价格参数和一网络状况参数；The first acquisition module is configured to acquire the evaluation parameters of each of the plurality of communication networks after receiving the service request; the evaluation parameters corresponding to each network include at least the price for executing the first service parameter and a network status parameter;
第二评估模块，用于根据所述评估参数对所述多个通信网络进行综合评估，得到每种通信网络各自的评估结果；The second evaluation module is configured to perform comprehensive evaluation on the plurality of communication networks according to the evaluation parameters, and obtain respective evaluation results of each communication network;
第二选择模块，用于根据综合评估结果从所述多个通信网络中选择至少一个目标通信网络；A second selection module, configured to select at least one target communication network from the plurality of communication networks according to a comprehensive evaluation result;
下发模块，用于将选择的目标通信网络下发到所述终端，使得所述终端的用户能够根据接收到的目标通信网络进行网络接入。A sending module, configured to send the selected target communication network to the terminal, so that the user of the terminal can perform network access according to the received target communication network.
本发明实施例中，首先接收一主叫终端发送的针对第一业务的业务请求信息，这里的第一业务可以为通话业务、数据传输业务和/或多媒体业务等，然后获取所述多个通信网络中的每个通信网络的评估参数，其中，每个网络对应的评估参数至少包括执行所述第一业务的价格参数和一网络状况参数，根据所述评估参数对所述多个通信网络进行综合评估，得到每种通信网络各自的评估结果，根据综合评估结果从所述多个通信网络中为所述终端选择至少一个目标通信网络，下发到所述终端，使得所述终端的用户能够根据接收到的目标通信网络进行网络接入。In the embodiment of the present invention, the service request information for the first service sent by a calling terminal is firstly received, where the first service may be call service, data transmission service and/or multimedia service, etc., and then the plurality of communication services are acquired. An evaluation parameter of each communication network in the network, wherein the evaluation parameter corresponding to each network includes at least a price parameter for executing the first service and a network status parameter, and the multiple communication networks are evaluated according to the evaluation parameter Comprehensive evaluation, obtaining respective evaluation results of each communication network, selecting at least one target communication network for the terminal from the plurality of communication networks according to the comprehensive evaluation results, and sending it to the terminal, so that the user of the terminal can Perform network access according to the received target communication network.
其中，确认最终接入网络的方式有两种：Among them, there are two ways to confirm the final access to the network:
<方式一>由用户侧选择最终接入网络，即所述接入网络选择装置选择的目标通信网络为多个，并对多个目标通信网络进行优先级排序，下发到所述终端，由所述终端的用户根据接收到的接入网络优先级列表选择一个最终接入网络进行网络接入。<Method 1> The user side selects the final access network, that is, the access network selection device selects multiple target communication networks, and prioritizes the multiple target communication networks, and sends them to the terminal, and the The user of the terminal selects a final access network for network access according to the received access network priority list.
<方式二>由网络侧选择最终接入网络，即所述接入网络选择装置只选择一个目标通信网络下发给所述终端，所述终端直接进行网络接入即可。<Method 2> The final access network is selected by the network side, that is, the access network selection device only selects one target communication network and sends it to the terminal, and the terminal can directly access the network.
本发明实施例提供的装置是通过综合评估多个通信网络的价格和网络状况来为所述终端选择接入网络的，其中，在获取多个通信网络的价格时，应当考虑到如果主叫终端在某一通信网络上具有与所述第一业务和/或被叫终端对应的签约优惠，这里的签约优惠包括签约的优惠业务和/或套餐，此时该通信网络的价格就不应当为正常针对第一业务的价格，而应当为对应的签约优惠价格，因此，在本发明实施例中，当所述主叫终端在多个通信网络中的第一通信网络中具有与所述第一业务和/或所述被叫终端对应的签约优惠时，所述第一获取模块用于根据所述签约优惠对应的业务费率确定所述第一通信网络的价格参数。The device provided by the embodiment of the present invention selects an access network for the terminal by comprehensively evaluating the prices and network conditions of multiple communication networks. There is a subscription discount corresponding to the first service and/or the called terminal on a certain communication network, where the subscription discount includes the subscribed preferential service and/or package, and the price of the communication network should not be normal at this time For the price of the first service, it should be the corresponding discounted subscription price. Therefore, in the embodiment of the present invention, when the calling terminal has and/or the subscription discount corresponding to the called terminal, the first obtaining module is configured to determine the price parameter of the first communication network according to the service rate corresponding to the subscription discount.
相关功能节点可以通过与HLR(Home Location Register，归属位置寄存器)交互，获取相关的签约信息，当主叫终端在所述第一通信网络中具有与所述第一业务和/或所述被叫终端对应的签约优惠时，所述装置的第一获取模块是根据所述签约优惠对应的业务费率来确定所述第一通信网络的价格参数，避免了因未考虑通信对端的情况和/或用户签约优惠的信息导致的价格参数的偏差，进一步避免了对多个通信网络进行综合评估的偏差，提高了用户体验和感知。Relevant function nodes can obtain relevant subscription information by interacting with HLR (Home Location Register, home location register), when the calling terminal has a connection with the first service and/or the called terminal in the first communication network When the terminal corresponds to the subscription discount, the first acquisition module of the device determines the price parameter of the first communication network according to the service rate corresponding to the subscription discount, avoiding the situation caused by not considering the situation of the communication peer and/or The deviation of the price parameter caused by the information of the user's subscription discount further avoids the deviation of the comprehensive evaluation of multiple communication networks, and improves the user experience and perception.
当主叫终端在所述第一通信网络中具有与所述第一业务和/或所述被叫终端对应的签约优惠时，第一通信网络的价格参数与其他通信网络相比应当是较低的，在实际中，为了提高选择接入网络的速度，可以只从所述第一通信网络中进行目标网络的选择，因此，本发明实施例提供了对应的接入网络选择装置的实现方式，当存在多个第一通信网络时，所述接入网络选择装置还包括：When the calling terminal has a subscription offer corresponding to the first service and/or the called terminal in the first communication network, the price parameter of the first communication network should be lower than that of other communication networks Yes, in practice, in order to increase the speed of selecting an access network, the target network can be selected only from the first communication network. Therefore, this embodiment of the present invention provides an implementation of a corresponding access network selection device, When there are multiple first communication networks, the access network selection device further includes:
第一评估模块，用于根据所述评估参数对所述多个第一通信网络进行综合评估，得到每个第一通信网络各自的第一评估结果；A first evaluation module, configured to perform a comprehensive evaluation on the plurality of first communication networks according to the evaluation parameters, and obtain a first evaluation result of each first communication network;
第一选择模块，用于当所述第一评估结果中存在满足预设要求的评估结果时，直接从对应的第一评估结果满足预设要求的第一通信网络中选择至少一个目标通信网络，否则触发所述第二评估模块。The first selection module is configured to directly select at least one target communication network from the first communication networks whose corresponding first evaluation results meet the preset requirements when there is an evaluation result that meets the preset requirements in the first evaluation results, Otherwise trigger the second evaluation module.
由于所述第一通信网络的价格参数已经较低，可以只根据第一通信网络的网络状况参数来对每个第一通信网络进行评估，这里的预设要求可以为大于一预设的阈值，第一选择模块选择第一评估结果的数值大于所述阈值的第一通信网络作为目标通信网络。上述过程通过在多个第一通信网络中进行目标通信网络的选择，不再需要获取其他网络的网络状况参数，提升了为所述终端选择接入网络的速度，减少了交互信息，降低了额外的网络负荷和选网时延。Since the price parameter of the first communication network is relatively low, each first communication network can be evaluated only according to the network condition parameter of the first communication network, and the preset requirement here can be greater than a preset threshold, The first selection module selects the first communication network whose value of the first evaluation result is greater than the threshold as the target communication network. The above process selects the target communication network among multiple first communication networks, and no longer needs to obtain network status parameters of other networks, which increases the speed of selecting an access network for the terminal, reduces interactive information, and reduces additional network load and network selection delay.
如果所述第一评估结果中存在多个满足预设要求的评估结果，本发明实施例提供的装置还可以从满足预设要求的第一通信网络中只选择一个作为目标通信网络下发给所述终端，即，当所述第一评估结果中存在多个满足预设要求的评估结果时，所述第一选择模块从对应的第一评估结果满足预设要求的第一通信网络中仅选择价格参数最低的第一通信网络作为目标通信网络。If there are multiple evaluation results that meet the preset requirements in the first evaluation results, the device provided by the embodiment of the present invention may also select only one of the first communication networks that meet the preset requirements as the target communication network and send it to the target communication network. The terminal, that is, when there are multiple evaluation results meeting the preset requirements in the first evaluation results, the first selection module only selects from the first communication network whose corresponding first evaluation results meet the preset requirements The first communication network with the lowest price parameter is used as the target communication network.
如果没有满足预设要求的第一通信网络存在，则触发所述第二评估模块，这时所述第一获取模块不需要获取所述多个通信网络的评估参数，只需要获取除所述第一通信网络外剩余网络的评估参数即可，这主要是由于不满足预设要求的第一通信网络已经被排除了。If there is no first communication network that meets the preset requirements, the second evaluation module is triggered. At this time, the first acquisition module does not need to obtain the evaluation parameters of the plurality of communication networks, but only needs to obtain parameters other than the first communication network. The evaluation parameters of the remaining networks other than the first communication network are sufficient, mainly because the first communication network that does not meet the preset requirements has been excluded.
同时，在进行综合评估时，如果只考虑各网络的网络质量，不考虑网络负载，可能导致根据价格及网络质量选出的目标通信网络由于网络拥塞而无法接入，因此，在上述的评估参数中，所述网络状况参数包括：网络质量参数和/或网络负载参数。At the same time, if only the network quality of each network is considered during the comprehensive evaluation, and the network load is not considered, the target communication network selected based on the price and network quality may be unable to access due to network congestion. Therefore, in the above evaluation parameters Wherein, the network status parameters include: network quality parameters and/or network load parameters.
得到每个通信网络各自评估结果的一种优选方式如下：A preferred way to obtain individual evaluation results for each communication network is as follows:
所述价格参数和网络状况参数具有各自的权重，价格参数和网络状况参数的权重之和为1，所述第二评估模块具体用于将每个通信网络的第一乘积和第二乘积的和作为通信网络对应的评估结果，其中第一乘积为价格参数的取值与价格参数的权重的乘积，第二乘积为网络状况参数的取值与网络状况参数的权重的乘积。The price parameter and the network status parameter have respective weights, and the sum of the weights of the price parameter and the network status parameter is 1, and the second evaluation module is specifically used to combine the sum of the first product and the second product of each communication network As the evaluation result corresponding to the communication network, the first product is the product of the value of the price parameter and the weight of the price parameter, and the second product is the product of the value of the network status parameter and the weight of the network status parameter.
下面结合实际具体说明综合评估的过程。The following is a concrete description of the comprehensive evaluation process in combination with the actual situation.
首先，根据相关策略，针对价格参数、网络质量参数和网络负载参数分别赋予不同的权重，每部分权重在0-1之间，各部分权重之和为1，根据策略，越重视的部分，赋予的权重越高；First, according to relevant strategies, different weights are assigned to price parameters, network quality parameters, and network load parameters. Each part has a weight between 0 and 1, and the sum of the weights of each part is 1. The higher the weight;
其次，针对不同的价格参数赋予每个网络的价格参数不同的值，取值可以在0-1之间，价格参数越低的网络，赋予的值越大；Secondly, according to different price parameters, the price parameters of each network are given different values, and the value can be between 0-1. The lower the price parameter of the network, the greater the value assigned;
再次，根据获取的网络质量参数，赋予每个网络的网络质量参数不同的值，取值可以在0-1之间，网络质量越好的网络，赋予的值越大；Thirdly, according to the obtained network quality parameters, different values are assigned to the network quality parameters of each network, and the value can be between 0-1. The better the network quality, the larger the assigned value;
再次，根据获取的网络负载参数，可以从网管中获取，赋予每个网络的网络负载参数不同的值，取值可以在0-1之间，网络负载越高的网络，赋予的值越低；Thirdly, according to the obtained network load parameters, it can be obtained from the network management, and the network load parameters of each network can be given different values, and the value can be between 0 and 1. The higher the network load, the lower the value assigned;
最后，将价格参数、网络质量参数和网络负载参数的权重分别与价格参数、网络质量参数和网络负载参数的数值相乘，三项乘积的和作为每个通信网络的综合评估结果。Finally, the weights of the price parameter, network quality parameter and network load parameter are multiplied by the value of the price parameter, network quality parameter and network load parameter respectively, and the sum of the three products is used as the comprehensive evaluation result of each communication network.
所述接入网络装置在对多个通信网络进行综合评估时，同时考虑价格、网络质量和网络负载，避免了根据价格及网络质量选出的目标通信网络由于网络拥塞而无法接入，影响用户感受；同时，所述接入网络装置将权重与对应参数的数值相乘，乘积的和做为每个通信网络的评估结果，在进行目标网络选择时可以直接按综合评估的数值由大到小选择目标通信网络。When the access network device comprehensively evaluates multiple communication networks, the price, network quality and network load are considered at the same time, so as to prevent the target communication network selected according to the price and network quality from being unable to access due to network congestion, affecting users At the same time, the access network device multiplies the weight by the value of the corresponding parameter, and the sum of the products is used as the evaluation result of each communication network. When selecting the target network, it can be directly evaluated from large to small according to the value of the comprehensive evaluation Select the target communication network.

步骤二，在收到所述业务请求后，所述装置获取多个通信网络中的每个通信网络的评估参数，这里的多个通信网络为A、B、C、D四个通信网络；Step 2, after receiving the service request, the device obtains evaluation parameters of each of the multiple communication networks, where the multiple communication networks are four communication networks A, B, C, and D;
步骤三，相关节点通过与HLR交互，确认了所述主叫终端在A通信网络上具有与通话业务对应的签约优惠套餐，在B通信网络上和被叫终端具有与通话业务对应的签约优惠业务，所述接入网络选择装置获取在A通信网络上的优惠套餐价格参数，在B网络上的与被叫终端对应的优惠业务价格参数，在C、D网络上的正常通话价格参数，以及A、B两个通信网络上的网络状况参数；Step 3, the relevant node confirms that the calling terminal has a preferential contract package corresponding to the call service on the A communication network, and has a contract preferential service corresponding to the call service on the B communication network with the called terminal by interacting with the HLR , the access network selection device obtains the preferential package price parameter on the A communication network, the preferential service price parameter corresponding to the called terminal on the B network, the normal call price parameter on the C and D networks, and the A , B network status parameters on the two communication networks;
步骤四，A、B两个网络对应所述第一通信网络，所述接入网络选择装置可以根据A、B两个通信网络上的网络状况参数对A、B两个通信网络进行评估，获得的评估结果如果为A、B两个通信网络均满足预设要求，即A、B两个通信网络的第一评估结果的数值均大于一预设的阈值；Step 4, the two networks A and B correspond to the first communication network, and the access network selection device can evaluate the two communication networks A and B according to the network status parameters on the two communication networks A and B, and obtain If the evaluation results of the two communication networks A and B meet the preset requirements, that is, the values of the first evaluation results of the two communication networks A and B are both greater than a preset threshold;
步骤五，所述接入网络选择装置可以选择A、B两个通信网络，并进行优先级排序，形成一接入网络优先级列表下发给所述终端，根据所述终端的用户的选择确定接入A或B通信网络，或者从A、B两个通信网络中选择价格参数最低的A通信网络作为目标网络，下发给所述终端，终端接入即可。Step 5, the access network selection device may select two communication networks A and B, and perform priority sorting to form an access network priority list and send it to the terminal, and determine according to the selection of the terminal user Access A or B communication network, or choose A communication network with the lowest price parameter from A and B communication networks as the target network, send it to the terminal, and the terminal can access it.
上述的步骤四中，根据A、B两个通信网络上的网络状况参数对A、B两个通信网络进行评估，获得的评估结果如果为A、B两个通信网络均不满足预设要求，则步骤五为获取C、D两个通信网络上的网络状况参数并对C、D两个网络进行综合评估，即将权重与对应参数的数值相乘，乘积的和做为每个通信网络的评估结果，并根据综合评估的数值由大到小选择目标网络下发给所述终端，同样地，在下发目标网络时，可以对C、D通信网络进行优先级排序，下发形成的接入网络优先级列表给所述终端，或由所述装置直接选择一个目标网络C下发给终端。In the above step 4, the two communication networks A and B are evaluated according to the network status parameters on the two communication networks A and B, and if the obtained evaluation results are that both communication networks A and B do not meet the preset requirements, Then step five is to obtain the network status parameters on the two communication networks C and D and comprehensively evaluate the two networks C and D, that is, to multiply the weight by the value of the corresponding parameter, and the sum of the products is used as the evaluation of each communication network As a result, the target network is selected from large to small according to the comprehensive evaluation value and sent to the terminal. Similarly, when the target network is delivered, the C and D communication networks can be prioritized, and the formed access network can be delivered. The priority list is given to the terminal, or a target network C is directly selected by the device and delivered to the terminal.
本发明实施例还提供了一种接入网络选择方法，用于为支持多个通信网络的终端选择接入网络，如图2所示，包括：The embodiment of the present invention also provides a method for selecting an access network, which is used to select an access network for a terminal supporting multiple communication networks, as shown in FIG. 2 , including:
步骤21，接收主叫终端发送的针对第一业务的业务请求信息；Step 21, receiving service request information for the first service sent by the calling terminal;
步骤22，在收到所述业务请求后，获取所述多个通信网络中的每个通信网络的评估参数；每个网络对应的评估参数至少包括执行所述第一业务的价格参数和一网络状况参数；Step 22, after receiving the service request, obtain the evaluation parameters of each communication network in the plurality of communication networks; the evaluation parameters corresponding to each network include at least a price parameter for executing the first service and a network status parameter;
步骤23，根据所述评估参数对所述多个通信网络进行综合评估，得到每种通信网络各自的评估结果；Step 23, performing comprehensive evaluation on the plurality of communication networks according to the evaluation parameters, and obtaining respective evaluation results of each communication network;
步骤24，根据综合评估结果从所述多个通信网络中选择至少一个目标通信网络；Step 24, selecting at least one target communication network from the plurality of communication networks according to the comprehensive evaluation result;
步骤25，将选择的目标通信网络下发到所述终端，使得所述终端的用户能够根据接收到的目标通信网络进行网络接入。Step 25, sending the selected target communication network to the terminal, so that the user of the terminal can perform network access according to the received target communication network.
本发明实施例提供的方法是通过综合评估多个通信网络的价格和网络状况来为所述终端选择接入网络的，其中，在获取多个通信网络的价格时，应当考虑到如果主叫终端在某一通信网络上具有与所述第一业务和/或被叫终端对应的签约优惠，这里的签约优惠包括优惠业务和/或套餐，此时该通信网络的价格就不应当为正常的业务价格，而应当为对应的签约优惠价格，因此，在本发明实施例中，当所述主叫终端在多个通信网络中的第一通信网络中具有与所述第一业务和/或所述被叫终端对应的签约优惠时，步骤22具体为根据所述签约优惠对应的业务费率确定所述第一通信网络的价格参数。The method provided by the embodiment of the present invention selects an access network for the terminal by comprehensively evaluating the prices and network conditions of multiple communication networks. There is a subscription discount corresponding to the first service and/or the called terminal on a communication network, where the subscription discount includes preferential services and/or packages, and the price of the communication network should not be a normal service at this time price, but should be the corresponding discounted subscription price. Therefore, in the embodiment of the present invention, when the calling terminal has a connection with the first service and/or the In case of a subscription discount corresponding to the called terminal, step 22 is specifically to determine the price parameter of the first communication network according to the service rate corresponding to the subscription discount.
相关功能节点可以通过与HLR(Home Location Register,归属位置寄存器)交互，获取相关的签约信息，当主叫终端在所述第一通信网络中具有与所述第一业务和/或所述被叫终端对应的签约优惠时，步骤22是根据所述签约优惠对应的业务费率来确定所述第一通信网络的价格参数，避免了因未考虑通信对端的情况和/或用户签约优惠的信息导致的价格参数的偏差，进一步避免了对多个通信网络进行综合评估的偏差，提高了用户体验和感知。Relevant function nodes can obtain relevant subscription information by interacting with HLR (Home Location Register, home location register), when the calling terminal has a connection with the first service and/or the called terminal in the first communication network When the subscription discount corresponding to the terminal, step 22 is to determine the price parameter of the first communication network according to the service rate corresponding to the subscription discount, avoiding the situation caused by not considering the situation of the communication peer and/or the information of the user subscription discount. The deviation of the price parameter further avoids the deviation of comprehensive evaluation of multiple communication networks, and improves user experience and perception.
当主叫终端在所述第一通信网络中具有与所述第一业务和/或所述被叫终端对应的签约优惠时，第一通信网络的价格参数与其他通信网络相比应当是较低的，在实际中，为了提高选择接入网络的速度，可以只从所述第一通信网络中进行目标网络的选择，因此，本发明实施例提供了对应的接入网络选择方法，当存在多个第一通信网络时，所述接入网络选择方法还包括：When the calling terminal has a subscription offer corresponding to the first service and/or the called terminal in the first communication network, the price parameter of the first communication network should be lower than that of other communication networks Yes, in practice, in order to increase the speed of selecting an access network, the target network can be selected only from the first communication network. Therefore, this embodiment of the present invention provides a corresponding method for selecting an access network. When there are multiple When a first communication network is used, the method for selecting an access network further includes:
步骤221，根据所述评估参数对所述多个第一通信网络进行综合评估，得到每个第一通信网络各自的第一评估结果；Step 221, performing a comprehensive evaluation on the plurality of first communication networks according to the evaluation parameters, and obtaining a respective first evaluation result of each first communication network;
步骤222，当所述第一评估结果中存在满足预设要求的评估结果时，直接从对应的第一评估结果满足预设要求的第一通信网络中选择至少一个目标通信网络，否则进入步骤23。Step 222, when there is an evaluation result that meets the preset requirements in the first evaluation results, directly select at least one target communication network from the first communication networks whose corresponding first evaluation results meet the preset requirements, otherwise go to step 23 .
由于所述第一通信网络的价格参数已经较低，可以只根据第一通信网络的网络状况参数来对每个第一通信网络进行评估，这里的预设要求可以为大于一预设的阈值，步骤222具体为选择第一评估结果的数值大于所述阈值的第一通信网络作为目标通信网络。上述过程通过在多个第一通信网络中进行目标通信网络的选择，不再需要获取其他网络的网络状况参数，提升了为所述终端选择接入网络的速度，减少了交互信息，降低了额外的网络负荷和选网时延。Since the price parameter of the first communication network is relatively low, each first communication network can be evaluated only according to the network condition parameter of the first communication network, and the preset requirement here can be greater than a preset threshold, Step 222 is specifically to select the first communication network whose value of the first evaluation result is greater than the threshold as the target communication network. The above process selects the target communication network among multiple first communication networks, and no longer needs to obtain network status parameters of other networks, which increases the speed of selecting an access network for the terminal, reduces interactive information, and reduces additional network load and network selection delay.
如果所述第一评估结果中存在多个满足预设要求的评估结果，本发明实施例提供的装置还可以从满足预设要求的第一通信网络中只选择一个作为目标通信网络下发给所述终端，即，当所述第一评估结果中存在多个满足预设要求的评估结果时，步骤222可以具体为从对应的第一评估结果满足预设要求的第一通信网络中仅选择价格参数最低的第一通信网络作为目标通信网络。If there are multiple evaluation results that meet the preset requirements in the first evaluation results, the device provided by the embodiment of the present invention may also select only one of the first communication networks that meet the preset requirements as the target communication network and send it to the target communication network. The terminal, that is, when there are multiple evaluation results that meet the preset requirements in the first evaluation results, step 222 may be specifically to select only the price from the first communication network whose corresponding first evaluation results meet the preset requirements The first communication network with the lowest parameter is used as the target communication network.
如果没有满足预设要求的第一通信网络存在，则进入步骤23，这时不需要获取所述多个通信网络的评估参数，只需要获取除所述第一通信网络外剩余网络的评估参数即可，这主要是由于不满足预设要求的第一通信网络已经被排除了。If there is no first communication network that meets the preset requirements, then enter step 23. At this time, it is not necessary to obtain the evaluation parameters of the plurality of communication networks, and only need to obtain the evaluation parameters of the remaining networks except the first communication network, that is, However, this is mainly because the first communication network that does not meet the preset requirements has been excluded.
同时，在进行综合评估时，如果只考虑各网络的网络质量，不考虑网络负载，可能导致根据价格及网络质量选出的目标通信网络由于网络拥塞而无法接入，因此，在上述的评估参数中，所述网络状况参数包括：网络质量参数和/或网络负载参数。At the same time, if only the network quality of each network is considered during the comprehensive evaluation, and the network load is not considered, the target communication network selected based on the price and network quality may be unable to access due to network congestion. Therefore, in the above evaluation parameters Wherein, the network status parameters include: network quality parameters and/or network load parameters.
得到每个通信网络各自评估结果的一种优选方式如下：A preferred way to obtain individual evaluation results for each communication network is as follows:
所述价格参数和网络状况参数具有各自的权重，价格参数和网络状况参数的权重之和为1，所述第二评估模块具体用于将每个通信网络的第一乘积和第二乘积的和作为通信网络对应的评估结果，其中第一乘积为价格参数的取值与价格参数的权重的乘积，第二乘积为网络状况参数的取值与网络状况参数的权重的乘积。The price parameter and the network status parameter have respective weights, and the sum of the weights of the price parameter and the network status parameter is 1, and the second evaluation module is specifically used to combine the sum of the first product and the second product of each communication network As the evaluation result corresponding to the communication network, the first product is the product of the value of the price parameter and the weight of the price parameter, and the second product is the product of the value of the network status parameter and the weight of the network status parameter.
本发明实施例基于上述流程给出了一种实现网络选择的相关功能实体，用于为支持多个通信网络的终端选择接入网络，如图3所示，包括：Based on the above process, the embodiment of the present invention provides a related functional entity for realizing network selection, which is used to select an access network for a terminal supporting multiple communication networks, as shown in FIG. 3 , including:
采集单元，用于周期或非周期性采集检测多个通信网络中每个通信网络的评估参数，所述评估参数至少包括执行对应业务的价格参数和一网络状况参数；The collection unit is used for periodically or non-periodically collecting and detecting evaluation parameters of each of the multiple communication networks, the evaluation parameters at least including a price parameter for executing a corresponding service and a network status parameter;

下发单元，将决策单元选择的结果下发给所述终端。The delivery unit is configured to deliver the result selected by the decision-making unit to the terminal.
为了减少由于数据更新带来的网络负荷，可以不对网络状况参数进行存储和更新，只在需要对相关网络评估时才由采集单元进行采集。In order to reduce the network load caused by data updating, the network status parameters may not be stored and updated, and the collection unit collects them only when relevant network evaluation is required.
