Detailed Description
The present invention will be described in further detail with reference to the following detailed description and accompanying drawings.
The first embodiment is as follows:
referring to fig. 1, the present disclosure relates to a method for switching a service from an original unstructured supplementary service data platform to a target unstructured supplementary service data platform, where fig. 1 mainly describes a processing flow of the original unstructured supplementary service data platform in a process of completing a whole task, and the method includes:
s101: generating and sending switching information for switching the service to a target unstructured supplementary service data service platform to a core network;
s102: and triggering the target unstructured supplementary service data platform by using the core network according to the switching information.
In the USSD service system, when a user needs to perform some USSD service processing using the system, a terminal is used to actively send a service processing request to an original unstructured supplementary service data platform through a core network. The terminal may be a commonly used mobile phone, a telephone, a PAD (PAD) device, or the like; for the request transmission method, it is common to preset specific numbers or characters such as # and the like. For example, when a user inputs a number or a symbol preset in the network by using a mobile phone keyboard, and presses a dial key, a Request may be sent to the network, where the Request may be a PUSSDR (Processing USSD Request) Request, and the network selects a service required by the user according to an instruction of the user and provides the service to the user. Therefore, before step S101 is executed, a first processing service request from the user is received, and the content requested by the user and the service to be processed can be known according to the first processing service request. And the original unstructured supplementary data service platform is configured with unstructured supplementary data service platforms corresponding to various services, which are usually configured by staff. The staff will know the service functions of other unstructured supplementary service data platforms, for example, the unstructured supplementary service data platform a has a function of inquiring balance; the unstructured supplementary data service platform B may be used for top-up. Thus, it is configured in advance, when the content of the received service processing request is that balance inquiry is needed, the processing to be performed is to switch the service to the unstructured supplementary service data platform a.
In step S101, when the original unstructured supplementary service data platform determines that the service to be processed needs to be completed by the target unstructured supplementary service data platform according to the first service processing request of the user, switching information is generated and sent to the core network. When the original unstructured supplementary service data platform receives a service processing request of a user, the request is analyzed, and then the service requested by the user can be known. The service request initiated by the user according to the first service processing request may be one or more, for example, the user may request only to query the balance, or may query the balance and the package usage status. Of course, there is a situation that a user requests a certain service, but the service needs to be supported by many sub-services to be completed, and the sub-services need to be completed by the cooperation of a plurality of unstructured supplementary service platforms. For those non-concerned, it is only necessary to determine whether the service to be processed needs to be completed by the target unstructured supplementary data service platform according to the first service processing request. First, a service request initiated by a user only needs to be processed by one unstructured supplementary service data platform, and for this case, the original unstructured supplementary service data platform may be needed to complete the processing, or the target unstructured supplementary service data platform may be needed to complete the processing. If the original unstructured supplementary service data platform is needed to complete the processing, the service switching is not needed, and the original unstructured supplementary service data platform completes the processing of all the services. If the target unstructured supplementary service data platform is required to complete the processing, the service to be processed includes all services required to be processed for the first service processing request. Next, a case where a service request initiated by a user only needs to be processed by two or more unstructured supplementary data service platforms is discussed, and for this case, the processing of possible tasks is sequential, and if the original unstructured supplementary data service platform is first required to perform partial processing, and then the target unstructured supplementary data service platform is required to perform processing, at this time, the service to be processed includes all the remaining services to be processed except the processed service. If the target unstructured supplementary service data platform is required to process firstly, all the services required to be processed belong to the services to be processed. It may also be that after one handover has been completed, the target unstructured supplementary service platform is required to process, and at this time, the to-be-processed service is a service that needs to be processed but has not been processed, in addition to the already-processed service, in all services that need to be processed for the first service processing request.
When the original unstructured supplementary service data platform judges that the service to be processed needs to be processed by the target unstructured supplementary service data platform according to the first processing service request of the user, switching information is generated, wherein the switching information comprises access information of the target unstructured supplementary service data platform and communication information of the user. The access information of the target unstructured supplementary service data platform may include an access code of the target unstructured supplementary service data platform, a GT (Global Title) code of an SIU (System interface unit) corresponding to the target unstructured supplementary service data platform, and the like. Generally, one unstructured supplementary service data platform may correspond to one SIU, or a plurality of unstructured supplementary service data platforms may correspond to the same SIU, and may be flexibly set according to specific situations. The user may initiate a first service processing request through a terminal such as a mobile phone or a telephone, and at this time, the communication information of the user may be a mobile phone number, a telephone number, and the like of the user. The switching information carries access information of the target unstructured supplementary service data platform, and is mainly used for the core network to find the target unstructured supplementary service data platform and communicate with the target unstructured supplementary service data platform so as to trigger the target unstructured supplementary service data platform to perform service processing. The communication information of the user is carried to facilitate the interaction between the target unstructured supplementary service data platform and the user. In one embodiment, the original unstructured supplementary service data platform sends the handover information by means of MAP signaling.
And then executing step S102, and triggering the target unstructured supplementary service data platform by using the core network according to the switching information. And after the original unstructured supplementary service data platform sends the switching information to the core network, the core network triggers the target unstructured supplementary service data platform according to the switching information to process the service to be processed.
In one embodiment, when the original unstructured supplementary service data platform determines that the service to be processed needs to be completed by the target unstructured supplementary service data platform according to the first service processing request of the user, an auxiliary session for relaying the interaction information between the target unstructured supplementary service data platform and the user is generated while sending the switching information to the core network. After a core network is utilized to trigger a target unstructured supplementary service data platform to process the service to be processed according to switching information, if the target unstructured supplementary service data platform needs to perform information interaction with a user, an original unstructured supplementary service data platform receives service processing information obtained by the target unstructured supplementary service data platform executing service function, and the service processing information is transmitted to the user; and receiving feedback information sent by the user according to the service processing information, and transmitting the feedback information to the target unstructured supplementary data service platform.
In addition, when the original unstructured supplementary service data platform detects that the processing of the target unstructured supplementary service data platform to the service to be processed is finished, the service is switched to the original unstructured supplementary service data platform. The specific process is to judge whether a service needing to be processed still exists, if so, the original unstructured supplementary data service platform controls and completes the processing of the service needing to be processed; otherwise, the original unstructured supplementary service data platform controls to finish all service processing.
Example two:
referring to fig. 2, fig. 2 mainly describes a processing flow completed on a core network in a process of completing a whole task, where the method includes:
s201: receiving switching information which is sent by an original unstructured supplementary service data platform and used for switching the service to a target unstructured supplementary service data platform;
s202: and generating a second processing service request according to the switching information, and sending the second processing service request to the target unstructured supplementary data service platform to trigger the target unstructured supplementary data service platform to process the service to be processed.
When a user initiates a first service processing request, the core network sends the first service processing request to the original unstructured supplementary service data platform. And the original unstructured supplementary service data platform generates switching information according to the first processing service request and sends the switching information to the core network. The core network executes step S201 to receive switching information for switching the service to the target unstructured supplementary service data platform, which is sent by the original unstructured supplementary service data platform. The switching information comprises access information of the target unstructured supplementary service data platform and communication information of the user. The access information of the target unstructured supplementary service data platform may include an access code of the target unstructured supplementary service data platform, a GT code of an SIU corresponding to the target unstructured supplementary service data platform, and the like. The user may initiate a first service processing request through a terminal such as a mobile phone or a telephone, and at this time, the communication information of the user may be a mobile phone number, a telephone number, and the like of the user. The switching information carries access information of the target unstructured supplementary service data platform, and is mainly used for the core network to find the target unstructured supplementary service data platform and communicate with the target unstructured supplementary service data platform so as to trigger the target unstructured supplementary service data platform to perform service processing. The communication information of the user is carried to facilitate the interaction between the target unstructured supplementary service data platform and the user. In one embodiment, the original unstructured supplementary service data platform sends the handover information by means of MAP signaling.
And then, executing step S202, the core network generating a second processing service request according to the exchanged information, and sending the second processing service request to the target unstructured supplementary data service platform to trigger the target unstructured supplementary data service platform to process the service to be processed. After the core network receives the switching information, if the original unstructured supplementary service data platform is sent in the form of MAP signaling, the core network receives the MAP signaling. After receiving the MAP signaling, the core network analyzes the signaling, and acquires an access code of a target unstructured supplementary service data platform, a GT code of a corresponding SIU and the like, and communication information of a user. And generating a second service processing request according to the content analyzed from the switching information, so as to trigger the target unstructured supplementary service data platform to perform service processing, wherein the request can also be a PUSSDR request.

s302: the core network receives the switching information;
s303: the core network generates a second processing service request according to the switching information, and sends the second processing service request to the target unstructured supplementary data service platform to trigger the target unstructured supplementary data service platform to process the service to be processed;

For the specific processes of steps S302 and S303, refer to the implementation processes of steps S201 and S202 of the unstructured supplementary data service switching method in the second embodiment. Then, step S304 is executed, after receiving the second service processing request sent by the core network, the target unstructured supplementary service platform triggers execution of its own service function, and in this process, interaction with the user may be required, for example, the request for joining the user is login, at this time, the user may be required to input a login name and a password, so that the target unstructured supplementary service platform generates service processing information and sends the service processing information to the original unstructured supplementary service platform, and the original unstructured supplementary service platform transparently transmits the service processing information to the user through the core network. The user can feed back feedback information aiming at the service processing information, and the specific mode is that the user terminal sends the return information to the original unstructured supplementary data service platform through the core network, and the original unstructured supplementary data service platform transmits the return information to the target unstructured supplementary data service platform. The target platform receives the feedback information and continues processing.
When the target unstructured supplementary service data platform finishes processing the service to be processed, an end message is sent to the original unstructured supplementary service data platform, the original unstructured supplementary service data platform finishes the auxiliary conversation after receiving the end message, meanwhile, the service is switched back to the original unstructured supplementary service data platform, and the original unstructured supplementary service data platform controls the session to be ended or the processing to be continued.
