Description

Method, device and system for implementing CRBT service, storage medium

Technical field

The present invention relates to the field of color ring tones, and in particular, to a method, an apparatus and system, and a storage medium for implementing a color ring back tone service.

Background technique

The circuit domain network structure diagram is as shown in FIG. 1. The user terminal UE completes call setup through a Node B (Node B) and a Radio Network Controller (RNC) access circuit domain (CS). The Mobile Switch Center Server (MSC Server) and the Media Gateway (MGW) are responsible for the establishment and communication of CS voice channels. The networks of different communication carriers are connected through the Gateway Mobile Switching Center (Gateway Mobile Switching Center, The GMSC Server and the network port bearer device GMGW are connected; in order to provide the user experience, the communication carrier provides the CRBT service to the user during the time when the user initiates the call to the called party. According to the actual situation, user calls (including calling and called) are divided into four application scenarios: the calling user initiates an intra-office call, the calling user initiates an outgoing call, the called user receives an intra-office call, and the called user receives an incoming call.

According to the above analysis, in the triggering process of the existing CRBT service, the MSC Server determines whether the user in the mobile network can trigger the CRBT, which is identified according to the customized supplementary service code signed by the user, and the existing call is executed. The primary and called CRBT processes can only be routed to the local ring back tone platform based on the customized ring code of the local ring tones.

In actual application, the CRBT user of the home operator B can roam to the network of the operator A, and then the calling party initiates or makes the called party to receive the call. For the inter-network roaming user, when the network user roams to the network, the calling party initiates When a new call or a called party receives a call, the MSC Server of the local network cannot treat the private supplementary service of the roaming user of the network and the user of the local network separately; therefore, there are:

1. If the network and the local office use different custom supplementary service codes to represent the CRBT service, it When the network user initiates or receives a call in the local office, the local switch can not correctly identify the CRBT service of the roaming user of the current network according to the customized supplementary service code, and the CRBT service cannot be triggered.

2. If the network and the local office use the same custom supplementary service code to represent the CRBT service, when the local network user initiates or receives a call, the local switch will continue to the local ring according to the customized supplementary service code. The ring back tone platform, not the ring back tone platform of the roaming user. That is, in the prior art, the MSC Server of the local network does not correctly identify the ring back tone platform that is routed to the network of the calling ring back tone carried by the roaming user of the network.

Therefore, how to solve the problem that the MSC Server of the local network does not correctly recognize the supplementary ring code of the calling ring tones of the roaming user of the network, and cannot perform the correct ring tones service, which is caused by the difference in the custom supplementary service codes of the different networks. The method for implementing the service is a technical problem that needs to be solved by those skilled in the art.

detailed description

It can be known from the prior art that user calls (including calling and called) are divided into four application scenarios: the calling user initiates an intra-office call, the calling user initiates an outgoing call, the called user receives an intra-office call, and the called user receives an incoming call. For the four application scenarios, the triggering process of the existing CRBT service is shown in Figure 2a to Figure 2d. The call is initiated only for the calling user to initiate the intra-office call. The other three cases are summarized:

As shown in Figure 2a, when the existing calling user initiates an intra-office call, the triggering process of the CRBT service includes:

S201: The calling terminal UE sends a SETUP message to the MSC Server.

S202: After receiving the SETUP message, the MSC Server queries the local configuration according to the customized supplementary service code stream of the calling user, and obtains the calling ring back tone information (including the calling color ring service indication and the calling color ring prefix) and saves the same.

S203: After the MSC Server returns a Call Proceeding message to the calling terminal UE,

S204-S207: The MSC Server initiates a routing process, and generates a routing information request to the HLR. The HLR sends a request for providing a roaming number to the called MSC Server (because the call is an intra-office call, the calling party and the called party belong to the same MSC Server), and the called party is called. The MSC Server provides a roaming number request response, and the message carries the roaming number; after receiving the request for providing the roaming number, the HLR responds to the calling MSC Server loop by the information request;

S208-S210: After receiving the routing information request response, the calling MSC Server finds that the called MSC, that is, the current MSC Server, sends a paging request to the called terminal B; after receiving the paging request, the terminal B sends the paging request to the MSC. The current MSC Server returns a paging response; after receiving the paging response, the calling MSC Server sends a call SETUP message to the called terminal B;

S211-S213: The calling MSC Server receives a Call Confirm message and an Alerting message sent by the called terminal B; the calling MSC Server sends a call to the calling terminal A. Send Alerting message;

S214-S215: After receiving the ringing message, the MSC Server queries the route according to the previously saved route prefix of the ring tones, and sends an IAM (Initiated Address Message) message to the local CRBT platform. The CRBT platform sends the ACM to the MSC Server. (Address Complete Message) message, after which the ring back tone platform starts to play the ring tones, and the calling terminal A starts to listen to the ring tones;

S216-S218: After receiving the response message sent by the called terminal B, the MSC Server sends a Connect message to the calling terminal A, enters the call, and sends a REL (Release Message) message to the ring back tone platform to notify the ring back tone. The platform stops playing.

As shown in Figure 2b, when the calling party initiates an outgoing call, the triggered ring tones process is similar to the in-office calling ring tone process shown in Figure 2a. The difference is that the calling party finds that the called MSC Server is not the current MSC Server. Send an IAM (Initiated Address Message) to the called MSC Server to complete the routing process at the called MSC Server. The called terminal sends an Alerting message to the called MSC Server, and the called MSC Server sends an ACM (Address Complete Message) to the calling MSC Server. The triggering process of the calling CRBT is the same. The subsequent called terminal sends a Connect message to the called MSC, and the called MSC Server sends an ANM (Answer Message) to the calling MSC Server. After the calling MSC Server receives the ANM (Answer Message), The ring back tone platform is notified to stop the ring back tone, and a Connect message is sent to the calling mobile phone, and the call enters the call.

As shown in Figure 2c, when the existing called user receives an intra-office call, the triggered ring tones of the called party are basically the same as the intra-office ring tones shown in Figure 2a. The difference is that the timing of obtaining the CRBT information is different: the MSC Server is receiving After the route response to the HLR, the local supplementary configuration is performed according to the user's custom supplementary service code stream, and the called CRBT information (including the called CRBT service indication and the called CRBT prefix) is saved and saved. Subsequent MSC Server receives the called party When the UE rings, it queries the route according to the previously saved route prefix of the called CRBT, and sends an IAM (Initiated Address Message) to the local ring back tone platform.

As shown in FIG. 2d, when the called user receives an incoming call, the triggered ring back tone process is basically the same as the inter-office call ring tone process shown in FIG. 2b. The difference is that the timing of obtaining the CRBT information is different. After receiving the route response from the HLR, the MSC Server B queries the local configuration of the called supplementary ringlet that is called by the user to obtain the called CRBT information (including the called CRBT service indication and the called CRBT prefix). ) and save it. When the MSC Server B receives the ringing of the called UE, it queries the route according to the previously saved route prefix of the called CRBT, and sends an IAM (Initiated Address Message) to the local ring back tone platform.

The invention will now be further illustrated by way of specific embodiments in conjunction with the accompanying drawings.

First embodiment:

FIG. 3 is a flowchart of a method for implementing a CRBT service according to the first embodiment of the present invention. As shown in FIG. 3, in the embodiment, the method for implementing a CRBT service provided by the present invention includes the following steps:

S301: Determine a home network of the terminal.

This step is generally performed by the calling terminal/called terminal when the calling terminal or the called terminal is called, or the call implementation unit in the network, such as the MSC Server, where the MSC Server is also referred to as the MSC Server of the local network;

The home network of the terminal is a network that provides communication services for the terminal (such as the CRBT service signed by the terminal). The home network can be the same as the network where the terminal is located. In this case, the terminal is actually the network terminal, and the home network can be different from the network where the terminal is located. At this point, the terminal is the other terminal;

S302: Parse the customized supplementary service code of the terminal according to the home network, and generate an analysis result.

The actual implementation of this step is to use the definition of the custom supplementary service code by the terminal home network to resolve the customized supplementary service code of the terminal, so that the correct resolution result can be obtained, such as whether the terminal subscribes to the CRBT service and the CRBT service. Type (caller ringtone and/or called ringtone), And information such as a ring back tone platform for providing a color ring back tone service to the terminal;

S303: Complete the CRBT service of the terminal according to the analysis result.

This step is based on the result of the analysis to determine how to handle the ring tone service during the call waiting time of the terminal. When the terminal subscribes to the CRBT service, the CRBT is provided for the caller to listen to. If the terminal is the contracted CRBT service, the call is only provided to the caller. bell.

In some embodiments, determining the home network of the terminal in the embodiment shown in FIG. 3 includes: determining the home network of the terminal when the terminal is calling or called; the embodiment is when determining the home network of the terminal. In this embodiment, the home network of the terminal is determined only when the terminal is called/called, and the power consumption is reduced. For example, when the terminal roams on a network without calling/called, the network only needs to provide the network. The signal connection is sufficient, and it is not necessary to care which network the terminal belongs to, because determining the home network of the terminal often needs to communicate with the terminal, which brings unnecessary power consumption.

In some embodiments, determining the home network of the terminal in the embodiment shown in FIG. 3 includes: acquiring a unique identification code of the terminal, determining a home network according to the unique identification code; the unique identification code includes a phone number corresponding to the terminal, and a mobile phone card. The IMSI (International Mobile Subscriber Identity) or the like can determine the identity of the network to which the terminal belongs.

In some embodiments, the customized supplementary service code according to the home network parsing terminal in the embodiment shown in FIG. 3 includes: parsing a customized supplementary service code according to a correspondence between the stored home network and a customized supplementary service code, and generating an analysis. As a result, the resolution result of the custom supplementary service code is obtained from the home network. In practical applications, the local MSC Server may obtain and correspondingly store other network definitions of their respective customized supplementary service codes. On this basis, when the terminal calls/calls, it can query according to the home network of the terminal. The definition of the supplementary supplementary service code to the home network, and then the correct supplementary service code corresponding to the terminal can be correctly parsed to obtain the correct analysis result. When storing, the storage may also directly store the IMSI and the IMSI corresponding to the customization. Supplement the content of the service code (such as the CRBT service indication and the CRBT prefix). Then, when using, you can directly find the content of the corresponding customized supplementary service code according to the IMSI of the terminal. More data needs to be stored, and the query is slower, but the basic understanding is based on the terminal's home network to resolve the terminal's custom supplementary service code; the local MSC Server may also be the active and terminal home network MSC when the terminal is calling/called. The server obtains the definition and parses the custom supplementary service code of the terminal.

In some embodiments, the parsing result in the embodiment shown in FIG. 3 includes a CRBT service indication. The completion of the CRBT service of the terminal according to the parsing result is: determining whether to provide the CRBT service for the terminal according to the CRBT service indication, and if yes, performing the CRBT service. .

In some embodiments, the parsing result in the embodiment shown in FIG. 3 further includes a CRBT prefix. The step of completing the CRBT service of the terminal according to the parsing result further includes: determining, according to the CRBT prefix, the home ring back tone platform of the terminal, and routing the CRBT service to The home color ring platform is executed.

In some embodiments, the parsing result further includes a CRBT prefix. The service execution module 43 in the embodiment shown in FIG. 4 is configured to determine the home ring back tone platform of the terminal according to the CRBT prefix, and route the CRBT service to the home CRBT platform.
