Description

Realization system and method of intelligent network enterprise virtual switchboard service

technical field

The present invention relates to the field of intelligent network communication, in particular to the use of intelligent network to realize Code Division Multiple Access (CDMA) intelligent network and Global System for Mobile Communication (Global System for Mobile Communication) (hereinafter referred to as GSM) intelligence A system and method for realizing a network enterprise virtual switchboard service.

Background technique

With the rapid development of the telecommunication network, there is an increasingly strong need to use existing network resources to provide users with richer value-added services. The enterprise virtual switchboard service is a new type of value-added service recently launched. Its basic business characteristics and functions are: provide one or more switchboard numbers for enterprise users (such as groups, companies, hotels, etc.), unify the external image of the enterprise, and provide users with links to other businesses as the enterprise portal. Typical services include manual number checking/transfer, company profile, etc. Any user can access the enterprise by dialing the switchboard number, obtain manual customer service or be transferred to an extension user in the enterprise.

The traditional method needs to realize the switchboard number and internal network of the enterprise by adding a small exchange in the enterprise and establishing a private line access relay with the telecom operator. The Chinese patent No. 02123906 provides a method for private branch exchange (PBX) (hereinafter referred to as PBX) small exchange to realize the call function between enterprise users and external users by using mobile relay. Therefore, there is no need to add a dedicated line access relay between the small exchange and the operator's network. The U.S. Patent No. 6,256,512 introduces access to Adjunct Mobile Switching Center (MSCA) equipment between the PBX and the wireless network, and through the originating mobile switching center (Mobile Switching Center) (hereinafter referred to as MSC) ), the service control point/home location register (Service Control Point/Home Location Register) (hereinafter referred to as SCP/HLR) and the message interaction among MSCA to realize the function that the wireless network user directly dials the short number of the PBX branch exchange to connect.

The enterprise virtual switchboard service needs to assign one or more switchboard numbers to the enterprise users who apply for the service. According to the network type of the number, it can be divided into public switched telephone network (Public Switched Telephone Network) (hereinafter referred to as PSTN) fixed user number, GSM user numbers and CDMA user numbers, corresponding to the intelligent network related protocols involved in the above three types of networks are Intelligent Network Application Protocol (Intelligent Network Application Protocol) (hereinafter referred to as INAP protocol), Mobile Network Enhanced Custom Application Logic (Customized Application foe Mobile Network Enhanced Logic) (hereinafter referred to as CAMEL) agreement and wireless intelligent network (Wireless Intelligent Network) (hereinafter referred to as WIN) agreement, the implementation required is also very different.

From the above description of the basic service features of the switchboard service, we can see that the basic service features include manual number search/transfer, that is, the calling user first calls the switchboard user number for manual agent service, and then selects the extension number. The call is routed to the extension number requested by the user.

In the current WIN protocol standard, the secondary connection function cannot be realized. The secondary connection function is that the calling user A dials the called user B and talks, and user B hangs up; user A does not need to hang up and the SCP instructs the user The function that A connects to the called user C again and talks. Specifically, when user A dials intelligent network user B, an intelligent network call process will be established between the switching device and the SCP. When user A and B talk and user B hangs up, the switching device will send an on-hook message to the SCP. Release the call after waiting for the SCP to respond. It is not possible to indicate to continue the call to another number C in the hook response message of the SCP again. A complete called call process is shown in Figure 1.

Similarly, in the CAMEL2 protocol standard, when the call ends and the called party disconnects, the Service Switching Point (Service Switching Point) (hereinafter referred to as SSP) reports the Basic Call State Model (hereinafter referred to as BCSM) event (terminal After the connection is disconnected (ie, T_disconnection), the SCP also cannot instruct the call to be connected to the third-party terminal number to initiate a second call. A complete called call process is shown in Figure 2.

Through the enterprise virtual switchboard service, the existing network resources of operators can be utilized to the greatest extent, and it is convenient to provide switchboard number services for many enterprise users without adding enterprise small switches. more users and revenue.

Fig. 3 is a schematic structural diagram of the realization system of the present invention. As shown in Figure 3, the network equipment entities involved in the present invention include CDMA exchange MSC/GMSC/SSP, GSM exchange MSC/GMSC/SSP, HLR, integrated intelligent network SCP (CDMASCP, GSMSCP, PSTNSCP), IP/SSP and customer service module.

First, the intelligent network subscription information of the switchboard user needs to be registered on the HLR. The basic triggers that should be configured for the CDMA intelligent network user include: originating terminal trigger (Initial_Termination), forwarding terminal trigger (Advanced_Termination), location and Call routing address available trigger (Location and Called_routing_address_available) etc.; For GSM intelligent network user can register terminal CAMEL subscription information (Termination-CAMEL SubscriptionInformation) (hereinafter referred to as T_CSI), registration service is GSM intelligent network switchboard guidance service. The user's home SCP is the comprehensive SCP where the guidance service is located.

Figure 4 shows a schematic diagram of a complete flow of dialing the CDMA switchboard number once. As shown in Figure 4, it includes the following steps:

Step 1, calling user A dials the switchboard number, and the CDMAMSC/GMSC where calling user A is located initiates a location request (LOCREQ) operation to the HLR. In this LOCREQ message, except including other mandatory parameters, it should also include TRIGTYPE (mobile terminal trigger Device (Mobile_Temination)), TRANSCAP and WINCAP parameters to indicate the type of trigger, the processing capability of the system and the processing capability of WIN (should support Call Control Directive (CCDIR), connection (CONN)).

Step 2, the above-mentioned HLR returns a locreq response message, which includes a trigger address list (TRIGADDRLIST), and triggers such as Initial_Termination, Advanced_Termination, Location and Called_routing_address_available are configured.

Step 3. The originating MSC triggers the Initial_Termination trigger, and sends an analysis information (ANLYZD) message to the relevant CDMASCP.

Step 4. The above-mentioned CDMASCP determines that the called number is the switchboard number of the enterprise and needs to be connected to the IP/SSP device. Allocate the temporary resource number (fixed prefix) that this call is connected to the above-mentioned IP/SSP device through the enterprise switchboard service leading service module, send a connection request (CONNRES) operation to the above-mentioned originating MSC/GMSC, and indicate to connect the above-mentioned independent IP device, wherein The parameter DSTDGTS is populated with the assigned temporary resource number. Different from the existing WIN protocol, the present invention does not need to initiate an acquisition request (SEIZERES) operation to the IP device to obtain the temporary resource number, but the CDMASCP allocates and manages the temporary resource number. And after sending the CONNRES operation, IP treats this call as an ordinary call, and will not send a temporary request (INSTREQ) operation to CDMASCP, so CDMASCP does not need to set the timeout timer that expects to receive the INSTREQ operation, but keeps this Call Waiting PSTNSCP returns the extension number.

Step 5. After receiving the CONNRES operation, the above-mentioned originating MSC/GMSC initiates a session connection request to the above-mentioned independent IP/SSP by using the assigned temporary resource number.

Step 6, the above-mentioned IP/SSP receives the initial address message (Initial Address Message) (hereinafter referred to as IAM) operation from the above-mentioned originating MSC/GMSC, wherein the called number is the fixed prefix temporary resource number allocated by the above-mentioned CDMASCP. The above IP/SSP analysis prefix triggers the fixed INAP procedure to the PSTNSCP device.

Step 7, the above-mentioned PSTNSCP enters the basic function processing module of the enterprise switchboard business, and instructs the above-mentioned IP/SSP to play a welcome tone to the user: XX Group welcomes you, please enter the extension number, please dial 1 for group introduction, and please dial 2 for manual services... ".

Step 8: The calling user A selects manual service, and if the extension number is directly input, step 10 is executed.

Step 9. The above-mentioned PSTNSCP applies to the agent system for queuing. After the queuing is successful, the agent is connected. After the agent answers, it provides manual services for the user. According to the user's request, the extension number to be connected is selected and sent to the above-mentioned PSTNSCP. After the service is over, the agent On-hook, the above-mentioned PSTNSCP captures the on-hook message, and continues automatic service processing.

Step 10, the above-mentioned PSTNSCP notifies the above-mentioned CDMASCP agent through the internal message interface that the processing is completed, and the above-mentioned CDMASCP sends a disconnection request (DISCONNRES) message to the above-mentioned originating MSC/GMSC to remove the voice channel connection with the above-mentioned IP/SSP. If there is no need to connect the extension number, the call flow ends, otherwise the above-mentioned PSTNSCP returns the collected extension real number C to the above-mentioned CDMASCP through the internal message interface.

Step 11. The above-mentioned CDMASCP sends an anlyzd return result to the above-mentioned originating MSC, in which the DMH_SVCID parameter is set to indicate that the switchboard service is executed.

Step 12. The above-mentioned originating MSC triggers the Advanced_Termination trigger, and sends an ANLYZD message to the above-mentioned relevant CDMASCP, requesting the above-mentioned CDMASCP to allocate an unconditional forwarding number.

Step 13, the above-mentioned CDMASCP sends anlyzd return result to the above-mentioned originating MSC, and the command is forwarded to the extension number C collected earlier. At the same time, the TRIGADDRLIST parameter configures triggers for call forwarding (Calling_Routing_Address_Available trigger (Calling_Routing_Address_Available), originating answer trigger (O_answer) and terminal disconnection trigger (O_Disconnect)).

Step 14, the originating MSC/GMSC analyzes the routing information, and prepares for call routing. The above-mentioned originating MSC triggers the Calling_Routing_Address_Available trigger, and sends an ANLYZD message to the CDMASCP related to the above-mentioned trigger.

Step 15, the above-mentioned CDMASCP sends an anlyzd return result message to the above-mentioned originating MSC. The DMH_SVCID parameter is set to indicate that the switchboard service is performed.

Step 16, the originating MSC/GMSC forwards the call. The call is answered.

Step 17, the above-mentioned originating MSC triggers an O_Answer trigger, and sends an OANSWER message to the CDMASCP related to the above-mentioned trigger.

Step 18: After the call is established, the called party hangs up, and the originating MSC triggers an O_Disconnect trigger, and sends an ODISCONNECT message to the CDMASCP related to the above trigger.

Step 19, the above-mentioned CDMASCP sends odisconnect to the above-mentioned originating MSC, and the MSC releases the call of the calling party.

Step 20, the process ends.

Figure 5 shows a schematic diagram of a complete flow of dialing the switchboard number of the GSM network once. As shown in Figure 5, it includes the following steps:

Step 1, calling user A dials the switchboard number, and the GSM intelligent network MSC/GMSC where calling user A is located initiates a Send Routing Information (SRI for short) operation to the HLR, and the above-mentioned HLR returns the subscription information T_CSI.

Step 2, the above-mentioned originating MSC obtains the SCP address of the user and the subscribed service according to the information in the above-mentioned T_CSI, and sends an Initial Detection Point (IDP) message to the integrated SCP (GSMSCP).

Step 3. The above-mentioned GSMSCP determines that the called number is the switchboard number of the enterprise and needs to be connected to the IP/SSP device. Send an Establish TemporaryConnection (hereinafter referred to as ETC) operation to the above originating MSC/GMSC, where the target number indicates the connection to the independent IP device. Here, the IP is required to configure the target number call as a normal call, and no longer send an Assist Request Instruction (ARI) message to the above-mentioned GSMSCP, so the above-mentioned GSMSCP does not need to set the timeout timer that expects to receive the ARI operation. Instead, the call is kept waiting for PSTNSCP to return the extension number.

Step 4. After receiving the ETC operation, the originating MSC/GMSC initiates a session connection request to the independent IP/SSP.

Step 5. The above-mentioned IP/SSP receives the IAM operation from the originating MSC/GMSC, wherein the called number is the fixed prefix number allocated by the above-mentioned GSMSCP. The above-mentioned IP/SSP treats this call as a normal call, and analyzes the prefix to trigger the INAP process of the fixed intelligent network to the PSTNSCP device.

Step 6.
