BEST MODE FOR CARRYING OUT THE INVENTION Hereinafter, the present invention will be described in detail with reference to the accompanying drawings. It should be noted that the embodiments in the present application and the features in the embodiments may be combined with each other without conflict. Unstructured supplementary services data (USSD) is a new type of interactive data service based on GSM network. It sends an instruction to the network by inputting some pre-set numbers or symbols of the network. This directive provides the services required, which are fast, convenient, connection-oriented, widely applicable, and highly real-time.

USSD 在通话状态下使用独立专用控制信道（Stand-alone Dedicated Control Channel, 简称为 SDCCH), 数据传输速率大约为 600kbps; 而在非通话状态时， USSD 使用快速辅助控制信道（Fast Associated Control Channel, 简称为 FACCH), 数据传输速率大约为 lkbps, 比 SMS传输速率高。 USSD在会话过程中一直保持通话连接，提供透明通道，不进行存储转发；而 SMS 在物理承载层没有会话通道，是一个存储转发***，用户完成一次查询需要进行多次会话过程。由于 USSD与 GPRS类似，在交互中保持一个会话过程，每次数据发送不需要重新建立信道，所以 USSD***对用户的呼叫请求是即时响应的，使响应时间大大加快，主要的响应时延已转移为应用服务器一端，响应时间比短消息快。基于 USSD具备上述众多优点，在本实施例中，将 USSD技术应用于呼叫业务，使进行呼叫的一方受限时由另一方单独承担通话费用，从而仍然能够进行呼叫。在本实施例中，提供了一种呼叫方法，图 1是根据本发明实施例的呼叫方法的流程图，如图 1所示，该流程包括如下步骤：步骤 S102, 网络侧接收请求呼叫的非结构化补充数据业务 USSD消息，其中，该The USSD uses a Stand-alone Dedicated Control Channel (SDCCH) in the call state, and the data transmission rate is about 600 kbps. In the non-talk state, the USSD uses the Fast Associated Control Channel (FAST). For FACCH), the data transfer rate is approximately lkbps, which is higher than the SMS transfer rate. The USSD maintains a call connection during the session and provides a transparent channel without storage and forwarding. The SMS does not have a session channel on the physical bearer layer. It is a store-and-forward system. The user needs to perform multiple sessions during a single query. Because USSD is similar to GPRS, it maintains a session process in the interaction, and does not need to re-establish the channel for each data transmission. Therefore, the USSD system responds immediately to the user's call request, which greatly speeds up the response time, and the main response delay has been transferred. For the application server side, the response time is faster than the short message. Based on the USSD having the above-mentioned numerous advantages, in the present embodiment, the USSD technology is applied to the call service, so that when the party making the call is limited, the other party alone bears the call charge, so that the call can still be made. In this embodiment, a call method is provided. FIG. 1 is a flowchart of a call method according to an embodiment of the present invention. As shown in FIG. 1, the process includes the following steps: Step S102: The network side receives a request for a call. Structured supplementary data service USSD message, where

USSD消息中携带有指示付费方为当前呼叫的主叫方或被叫方的信息；步骤 S104, 将该 USSD消息发送至 USSD中心；步骤 S106, 获取该 USSD中心与该主叫方或被叫方协商后反馈的呼叫计费方式，并根据该呼叫计费方式继续当前呼叫，其中，该呼叫计费方式可以为主叫方付费或者被叫方付费。通过上述步骤，通过在网络侧与 USSD中心实现的交互获取呼叫计费方式，根据该呼叫计费方式进行呼叫，相比于现有技术中在通话一方停机等通话受限时不能进行呼叫的情况，通过选择协商的呼叫计费方式，在通话一方通话受限的情况下，由另一方承担全部通话费用来进行呼叫，提高了用户体验，并且达到了在用户停机等通话受限的情况下，有效使用资源的效果。在通话一方出现停机或是余额限制等通话受限的情况下，而另一方希望承担受限方的全部费用而进行本次呼叫，例如，当被叫方通话受限，主叫方希望承担全部的通话费用时，该主叫方付费包括：由该主叫方承担该被叫方在完成当前呼叫时所需的所有费用，例如，被叫方能够接受主叫方对其呼叫付费的服务费用；而当主叫方通话受限时，被叫方来承担全部的通话费用时，该被叫方付费包括：由该被叫方承担该主叫方在完成当前呼叫时所需的所有费用，例如，主叫方能够接受被叫方对其呼叫付费的服务费用。为了对希望付费的一方能够实现付费功能，在将该 USSD消息发送至该 USSD中心之前，网络侧对该主叫方或被叫方进行鉴权，在鉴权通过的情况下，将该 USSD消息发送给该 USSD中心，鉴权的方式可以很多种，例如，对呼叫计费方式中要求付费的一方的帐户进行查询，判断该付费方是否有能力进行付费，另外，在网络侧对主叫方或是被叫方进行鉴权，有利于直接获取用户信息，充分利用网络资源，并且实施较为简单。网络侧将该 USSD消息发送给该 USSD中心的方式可以有很多种，例如，该 USSD 消息中携带有接入码；该网络侧根据预先设置的接入码与该 USSD中心的标识的对应关系，获取与该 USSD消息中携带的接入码对应的该 USSD中心的标识，将该 USSD 消息发送给该标识对应的该 USSD 中心，例如，根据 USSD 消息中携带的接入码与 USSD 中心的地址的对应关系，将该 USSD 消息发送给与该 USSD 中心地址对应的 USSD中心。又例如，网络侧还可以主动建立与主叫的 USSD连接，获取主叫发送过来的 USSD回应消息，将 USSD消息发送至 USSD中心。该 USSD中心与该主叫方或被叫方协商反馈呼叫计费方式也可以有很多种，例如，该 USSD中心接收该 USSD消息；该 USSD中心向该主叫方或被叫方发送呼叫提示信息；根据该主叫方或被叫方返回响应消息，确定该主叫方或被叫方接受付费，该 USSD 中心向该网络侧反馈该呼叫计费方式，上述为 USSD中心通过发送提示信息的方式进行确认付费方是否接受付费，当然，也可以通过付费方设置自己默认付费的方式来使 USSD中心得知付费方接受付费。在本实施例中还提供了一种呼叫装置，该装置用于实现上述实施例及优选实施方式，已经进行过说明的不再赘述。如以下所使用的，术语 "模块"可以实现预定功能的软件和 /或硬件的组合。尽管以下实施例所描述的装置较佳地以软件来实现，但是硬件，或者软件和硬件的组合的实现也是可能并被构想的。图 2是根据本发明实施例的呼叫装置的结构框图，如图 2所示，该装置包括接收模块 22、发送模块 24和呼叫模块 26。下面对该装置进行说明。接收模块 22，设置为网络侧接收请求呼叫的非结构化补充数据业务 USSD消息，其中，该 USSD消息中携带有指示付费方为当前呼叫的主叫方或被叫方的信息；发送模块 24，连接至该接收模块 22，设置为将该 USSD消息发送至 USSD中心；呼叫模块 26，连接至该发送模块 24，设置为获取该 USSD中心与该主叫方或被叫方协商后反馈的呼叫计费方式，并根据该呼叫计费方式继续当前呼叫。该呼叫付费方式包括主叫方付费和被叫方付费，该主叫方付费包括：由该主叫方承担该被叫方在完成当前呼叫时所需的所有费用；该被叫方付费包括：由该被叫方承担该主叫方在完成当前呼叫时所需的所有费用。图 3是根据本发明实施例的优选呼叫装置的结构框图，如图 3所示，该装置除包括图 2所示的模块外，还包括鉴权模块 28，连接至该接收模块 22和该发送模块 24，设置为在将该 USSD消息发送至该 USSD中心之前，该网络侧对该主叫方或被叫方进行鉴权，在鉴权通过的情况下，将该 USSD消息发送给该 USSD中心。较选地，该 USSD消息中还携带有接入码，该发送模块，还设置为该网络侧根据预先设置的接入码与该 USSD中心的标识的对应关系，获取与该 USSD消息中携带的接入码对应的该 USSD中心的标识，将该 USSD消息发送给该标识对应的该 USSD中心。在本实施例中提供了一种基于运营商数据库，移动用户终端（例如， ME)，在进行呼叫时，由一方单独承担全部通话费用的综合解决方案。该方案可以根据用户的具体需求来选择不同的处理方式，下面分别以主叫承担全部通话费用和被叫承担全部通话费用来说明。一：被叫承担全部通话费用。 The USSD message carries the information indicating that the paying party is the calling party or the called party of the current call; Step S104, the USSD message is sent to the USSD center; Step S106, acquiring the USSD center and the calling or called party After the negotiation, the call charging mode is fed back, and the current call is continued according to the call charging mode, wherein the call charging mode may be paid by the calling party or the called party. Through the above steps, the call charging mode is obtained through the interaction between the network side and the USSD center, and the call is performed according to the call charging mode, which is not possible when the call is restricted when the call is stopped, such as when the call is down. By selecting the negotiated call billing method, when the call of the call party is limited, the other party bears the total call charge to make the call, which improves the user experience and achieves the limitation of the call when the user is down, etc. The effect of using resources effectively. In the case where the call side has a down call or the balance limit is limited, and the other party wants to bear the full cost of the restricted party, the call is made. For example, when the called party has limited calls, the calling party wishes to assume all the calls. The calling party's payment includes: The calling party bears all the expenses required by the called party to complete the current call, for example, the called party can accept the calling party's service fee for paying the call. When the called party has limited call and the called party bears all the call charges, the called party pays: the called party bears all the expenses required by the calling party to complete the current call. For example, the calling party can accept the service fee of the called party paying for its call. In order to implement the payment function for the party that wants to pay, the network side authenticates the calling party or the called party before sending the USSD message to the USSD center, and if the authentication is passed, the USSD is cancelled. The information can be sent to the USSD center. There are many ways to authenticate. For example, query the account of the party that requires payment in the call billing mode to determine whether the payer has the ability to pay. In addition, the caller is on the network side. The party or the called party performs authentication, which is beneficial to directly obtaining user information, making full use of network resources, and being relatively simple to implement. The network side can send the USSD message to the USSD center in a variety of ways. For example, the USSD message carries an access code. The network side according to the correspondence between the preset access code and the identifier of the USSD center. Obtaining the identifier of the USSD center corresponding to the access code carried in the USSD message, and sending the USSD message to the USSD center corresponding to the identifier, for example, according to the access code carried in the USSD message and the address of the USSD center. Corresponding relationship, the USSD message is sent to the USSD center corresponding to the USSD center address. For example, the network side can also actively establish a USSD connection with the calling party, obtain a USSD response message sent by the calling party, and send the USSD message to the USSD center. The USSD center may negotiate with the calling party or the called party for a plurality of feedback call charging methods. For example, the USSD center receives the USSD message; the USSD center sends a call prompt message to the calling party or the called party. According to the returning response message of the calling party or the called party, determining that the calling party or the called party accepts the payment, the USSD center feeds back the charging mode of the call to the network side, and the foregoing is a manner in which the USSD center sends the prompt information. Confirm whether the payer accepts the payment. Of course, the payer can also set the default payment method to let the USSD center know that the payer accepts the payment. In the embodiment, a call device is also provided, which is used to implement the above-mentioned embodiments and preferred embodiments, and has not been described again. As used hereinafter, the term "module" may implement a combination of software and/or hardware of a predetermined function. Although the apparatus described in the following embodiments is preferably implemented in software, hardware, or a combination of software and hardware, is also possible and conceivable. 2 is a block diagram showing the structure of a calling device according to an embodiment of the present invention. As shown in FIG. 2, the device includes a receiving module 22, a transmitting module 24, and a calling module 26. The device will be described below.
