Description

Intelligent network enterprise virtual switchboard business realization system 3⁄4 method

TECHNICAL FIELD The present invention relates to the field of intelligent network communications, and in particular to an intelligent network for implementing Code Division Multiple Access (CDMA) intelligent network and Global System for Mobile Communication (hereinafter referred to as GSM). The system and method for realizing the virtual switchboard business of the intelligent network enterprise.

BACKGROUND OF THE INVENTION With the rapid development of telecommunication networks, the use of existing network resources to provide users with more abundant value-added services is increasingly demanding, and the enterprise virtual switchboard business is a new type of value-added service recently introduced. Its basic business characteristics and functions are: Provide one or more total ft numbers for enterprise users (such as groups, companies, hotels, etc.) to unify the external image of the enterprise, and use this as a portal for the enterprise to provide users with links to other businesses. Typical services include manual check/transfer, company profile, and more. Any user can access the enterprise by dialing the switchboard number, obtain customer service from the customer service or transfer to the extension user in the enterprise.

In the traditional way, the enterprise switchboard number and the internal network need to be realized by adding a small switch in the enterprise and establishing a private line access relay with the telecommunication operator. The Chinese patent No. 02123906 provides a method for a private branch exchange (PBX) small switch to realize the call function between an enterprise user and an external user by using a mobile relay. Therefore, there is no need to add a dedicated line access trunk between the small switch and the carrier network. US Patent No. 6,256,512 introduces an Adjunct Mobile Switching Center (MSCA) device between the PBX and the wireless network, and through the Mobile Switching Center (hereinafter referred to as MSC). ), Service Control Point / Home Location Register (Service Control Point/Home) Location Register) (hereinafter referred to as SCP/HLR) and message interaction between MSCA enable the wireless network user to directly dial the PBX PBX short number connection function.

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 a public switched telephone network (PSTN) fixed subscriber number, The GSM subscriber number and the CDMA subscriber number, the intelligent network related protocols involved in the above three types of networks are the Intelligent Network Application Protocol (hereinafter referred to as the INAP protocol) and the mobile network enhanced custom application logic (Customized Application foe Mobile Network). Enhanced Logic (hereinafter referred to as CAMEL) protocol and Wireless Intelligent Network (WIN) protocol, the implementation methods required are also very different.

As can be seen from the above description of the basic service characteristics of the switchboard service, the basic service features include manual directory/transfer, that is, the calling user first calls the switchboard user number for the manual agent service, and then selects the extension number, and the agent attendance will hang up after the agent The call is connected to the extension number requested by the user.

In the current WIN protocol standard, the secondary connection function cannot be implemented. The secondary connection function means that the calling user A dials the called user B and calls the user B to hang up; the user A does not need to hang up and the user is instructed by the SCP. A is connected to the called user C and talks. Specifically, when user A dials the intelligent network user B, an intelligent network call flow is established between the switching device and the SCP. After the user A and B talk and the user B hangs up, the switching device sends an on-hook message to the SCP. The call is released after waiting for the SCP to respond. The call cannot be re-instructed to continue to another number C in the SCP's On-hook response message. A complete called call flow is shown in Figure 1.

Similarly, in the CAMEL2 protocol standard, after the call is disconnected, the Service Switching Point (hereinafter referred to as SSP) reports the Basic Call State Model (hereinafter referred to as BCSM) event (terminal). After the disconnection, ie T_ disconnection), the SCP also cannot indicate that the call is connected to the third-party terminal number again. The code initiates a second call. A complete called call flow is shown in Figure 2.

The operator can set up a number of agent attendants to perform manual services as needed, and the switchboard system completes the transfer of the agent system. For example, the switchboard number applied by an enterprise is 13306380001. When other users dial the number, they can hear the automatic notification voice: "XX Group welcomes you, please enter the extension number, please dial 1 for group introduction, 2 for manual service... "When the user selects the manual service, the agent provides the enterprise secretarial service and the manual transfer extension service to the user. Through the enterprise virtual switchboard service, the existing network resources of the operator can be utilized to the greatest extent, and the switchboard number service can be conveniently provided for many enterprise users without adding an enterprise small switch, which is convenient for the enterprise user and also brings the operator More users and income.

3 is a schematic structural view of an implementation system of the present invention. As shown in FIG. 3, the network device entity involved in the present invention includes a CDMA switch MSC/GMSC, a GSM switch MSC/GMSC:, an HLR, an integrated intelligent network SCP (CDMASCP, GSMSCP, PSTNSCP. IP/SSP, and a 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:

(Initial-Termination), Advanced-Termination, Location and Called-routing address-available triggers, etc. For GSM intelligent network users can register terminal CAMEL Termination-CAMEL Subscription Information (hereinafter referred to as T-CSI), and the registration service is the GSM intelligent network switchboard guidance service. The user belongs to the SCP as the integrated SCP where the business is guided.

Figure 4 shows a complete flow chart of a single CDMA switchboard number. As shown in FIG. 4, it includes the following steps: Step 1. The calling user A dials the switchboard number, and the CDMAMSC/GMSC where the calling user A is located initiates a location request (LOCREQ) operation to the HLR, and the LOCREQ message includes other mandatory items. In addition to the parameters, it should also include TRIGTYPE (Mobile-Temination), TRANSCAP and WINCAP parameters. To indicate the type of trigger, the processing power of the system, and the processing power of WIN (Call Control Directive (CCDIR), Connection (CONN)) should be supported.

Step 2: The above HLR returns a locreq response message, which includes a trigger address list (TRIGADDRLIST), and is configured with triggers such as Initial- Termination, Advanced-Termination, Location and Called-route-address-availability.

Step 3. The originating MSC triggers an Initial- Termination trigger and sends an analysis information (ANLYZD) message to the associated CDMA SCP.

Step 4. The CDMA SCP determines that the called number is the enterprise switchboard number and needs to be connected to the IP/SSP device. Allocating a connection request (CONNRES) operation to the originating MSC/GMSC by using the enterprise switchboard service preamble service module to allocate the call to the temporary resource number (fixed prefix) of the IP/SSP device, indicating that the independent IP device is connected, wherein The parameter DSTDGTS fills in the assigned temporary resource number. Different from the existing WIN protocol, the present invention does not need to initiate a SEIZERES operation to the IP device to obtain the temporary resource number, but the CDMA SCP allocates the management temporary resource number. And after sending the CONNRES operation, the IP treats the call as a normal call and does not send a temporary request (INSTREQ) operation to the CDMA SCP. Therefore, the CDMA SCP does not need to set a timeout timer that expects to receive the INSTREQ operation, but keeps this. The call waits for the PSTNSCP to return the extension number.

Step 5: After receiving the CONNRES operation, the originating MSC/GMSC initiates a voice connection request to the independent IP/SSP by using the allocated temporary resource number.

Step 6: The IP/SSP receives an Initial Address Message (IAM) operation from the originating MSC/GMSC, where the called number is a fixed prefix temporary resource number allocated by the foregoing CDMA SCP. The above IP/SSP analysis prefix triggers the fixed intelligent network INAP process to the PSTNSCP device.

Step 7: The PSTNSCP enters the basic function processing module of the enterprise switchboard service, and instructs the IP/SSP to play the welcome tone to the user: Welcome to the XX Group, please enter the extension number Code, please dial 1 for group introduction, 2 for manual service...".

Step 8. The calling user A selects the manual service. If the extension number is directly input, go to step 10.

Step 9: The PSTNSCP applies for queuing to the agent system. After the queuing is successful, the agent accesses the agent. After the agent answers, the user is provided with a manual service. The user selects the extension number to be connected according to the user request and sends the number to the PSTNSCP. After the service ends, the agent is seated. On-hook, the above PSTNSCP captures the on-hook message and continues the automatic service processing.

Step 10: The PSTNSCP notifies the CDMA SCP agent that the CDMA SCP is processed by the internal message interface, and the CDMA SCP sends a DISCONN ES message to the originating MSC/GMSC to disconnect the voice channel of the IP/SSP. If the extension number is not required to be connected, the call flow ends. Otherwise, the PSTNSCP returns the collected extension real number C to the above CDMA SCP through the internal message interface.

Step 11. The CDMA SCP sends an alyzd return result to the originating MSC, where the DMH-SVCID parameter is set to indicate that the switchboard service is performed.

Step 12: The originating MSC triggers an Advanced_Termination trigger, and sends an ANLYZD message to the related CDMA SCP, requesting the CDMA SCP to allocate an unconditional forwarding number.

Step 13. The CDMA SCP sends an anlyzd return result to the originating MSC, and the command forwards to the previously collected extension number C:. At the same time, the TRIGADDRLIST parameter is configured for call forwarding triggers (Calling-Routing-Address-Available, Originating Answer Trigger (O- answer) and Terminal Disconnect Trigger (0-Disconnect) )).

Step 14. The originating MSC/GMSC analyzes the routing information and prepares to route the call. The originating MSC triggers a Calling-Routing-Address-Available Trigger and sends an ANLYZD message to the CDMA SCP associated with the trigger.

Step 15. The CDMA SCP sends an anlyzd return result message to the originating MSC. The DMH_SVCID parameter is set to indicate that the switchboard service is executed. Step 16. The foregoing originating MSC/GMSC forwards the call. The call is answered. Step 17, the originating MSC triggers a 0-Answer trigger, and sends an OANSWER message to the CDMA SCP associated with the trigger.

Step 18: After the call is established, the called party hangs up, and the originating MSC triggers a 0-Disconnect trigger, and sends an ODISCONNECT message to the CDMA SCP associated with the trigger.

Step 19. The CDMA SCP sends an odisconnect to the originating MSC, and the MSC releases the call of the calling party.

Step 20. The process ends.

Figure 5 shows the complete flow of a call to the GSM network switchboard number. As shown in FIG. 5, the method includes the following steps: Step 1. The calling user A dials the switchboard number, and the GSM intelligent network MSC/GMSC where the calling user A is located sends a Send Routing Information (SRI) operation to the HLR. The above HLR returns the subscription information T_CSI.

Step 2: The originating MSC obtains the SCP address and the contracted service that the user belongs according to the information in the T-CSI, and sends an Initial Detection Point (IDP) message to the integrated SCP (GSMSCP).

Step 3: The GSMSCP determines that the called number is the enterprise switchboard number and needs to be connected to the IP/SSP device. An Establish Temporary Connection (ETC) operation is sent to the originating MSC/GMSC, where the target number indicates that the independent IP device is connected. Here, the IP is required to configure the target number call as a normal call, and no Assist Request Instruction (hereinafter referred to as ARI) message is sent to the GSM SCP. Therefore, the GSM SCP does not need to set a timeout timer that is expected to receive the ARI operation. Instead, keep this call waiting for the 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 IP/SSP receives the IAM operation from the originating MSC/GMSC, where the called number is a fixed prefix number allocated by the GSM SCP. The above IP/SSP treats the call as a normal call, and analyzes the prefix to trigger the fixed intelligent network INAP process to the PSTNSCP device.

Step 6: The PSTNSCP enters the basic function processing module of the enterprise switchboard service, and instructs the IP/SSP to play the welcome tone to the user: XX Group welcomes you, please input the extension number, please dial 1 for group introduction, 2 for manual service.

Step 7. The calling user A selects the manual service. If you directly enter the extension number, go to step 9.

Step 8: The PSTNSCP applies for queuing to the agent system. After the queuing is successful, the agent accesses the agent. After the agent answers, the user is provided with a manual service. The user selects the extension number to be connected according to the user request and sends the number to the PSTNSCP. After the service ends, the agent is seated. On-hook, the above PSTNSCP captures the on-hook message and continues the automatic service processing.

Step 9. The PSTNSCP notifies the GSM SCP server that the GSM SCP is processed by the internal message interface, and the GSM SCP sends a Disconnect Forward Connection message to the originating MSC/GMSC to disconnect the IP/SSP. If the extension number is not required, the call flow ends. Otherwise, the PSTNSCP returns the collected extension real number C to the GSMSCP through the internal message interface.

Step 10: After the GSMSCP sends a request report BCSM Event (RRBE) or Apply Charging (AC) message, the CONNECT message is sent to the originating MSC, where the destination route address parameter indicates The extension destination number to which the extension should be sent.

Step 11. The originating MSC/GMSC forwards the call, and the call is answered. Step 12: The originating MSC reports an Apply Charging Report (ACR) to the GSM SCP.

Step 13. After the call is established, the called party hangs up, and the originating MSC reports the BCSM event. Event Report BCSM (ERB) is given to the relevant GSM SCP. Step 14. The GSM SCP sends a call release to the originating MSC (Release).

Call). The originating MSC releases the call.

Step 15. The process ends.

The above is a detailed description of the working principle of the present invention, but this is merely a visual example for the purpose of understanding, and should not be construed as limiting the scope of the invention. Also, various possible modifications or substitutions may be made in accordance with the description of the technical solutions of the present invention and the preferred embodiments thereof, and all such changes or substitutions are intended to fall within the scope of the appended claims.
