Example 1

In this embodiment, an analog call office (hereinafter referred to as the local office) is used to simulate the originating call of the calling user as an example. Referring to FIG. 1, the embodiment of the present invention provides a method for simulating a call, which specifically includes the following steps:

Step 101: The operator sends a request message for simulating the calling user to call the called user to the MSC (Mobile Switching Center) through the client/network management station.

The operator can send a request message simulating the calling user to call the called user through the network management station connected to the MSC of the local office, or send an analog calling user to call the called party through a GUI (Graphical User Interface) interface. The request message of the user may be defined by the operator. For example, information such as the calling number, the calling location area cell and the called number may be specified in the message, and the request message may be an A port or an Iu port message. .

Step 102: After receiving the request message that the calling user calls the called user, the local MSC obtains the data of the calling user according to the information of the calling user specified in the request message. The local MSC can also return a call response message to the client/network management station.

Further, referring to FIG. 2, it is also possible to introduce a monitoring phone during the process of simulating the call, explain to the called user that the test is currently in progress, and check whether the voice path between the simulated calling user and the called user is normal, so the master is acquired. The user's data can also include the following steps:

The MSC sends an IAM (Initial Address Message) to the PSTN (Public Switched Telephone Network) to call the monitoring phone. The IAM message can be defined by the device vendor, and can carry information such as a monitoring phone number. After receiving the IAM message, the PSTN returns an ACM (Address Complete Message) ringing message and an ANM (Answer Message) to the local MSC. Response message. After receiving the ACM ringing message and the ANM response message, the local MSC returns a response message to the network management station/client to inform the network management station/client that the monitoring phone is connected.

The specific process for the local MSC to obtain the calling user data according to the information of the calling user in step 102 is as follows: The local MSC determines whether the VLR (Visit Loaction Register) is in accordance with the information of the calling user specified in the received request message. There is data of the calling user (that is, whether the calling user is in the local office), if there is, the data of the calling user is read from the VLR; otherwise, the local MSC initiates a data recovery process to the HLR (Home Loaction Register) , receiving data of the calling user inserted by the HLR.

The process in which the MSC initiates a data recovery process to the HLR is as follows:

The MSC sends a restoreData request message to the HLR. After receiving the restoreData request message, the HLR sends an insertSubscriberData request message to the local MSC, where the request message carries the calling user data, and the HLR requests the message through the insertSubscriberData. The MSC inserts the calling subscriber data; after receiving the insertSubscriberData request message sent by the HLR, the local MSC extracts the calling subscriber data, and returns an insertSubscriberData response message to the HLR, indicating that the calling subscriber data has been received; after receiving the insertSubscriberData response message, the HLR receives the response message. , returning a restoreData response message to the local MSC, indicating that the data recovery process is completed.

Further, referring to FIG. 2, if the caller number specified by the operator in step 101 is MSISDN (Mobile Station International Integrated Service Digital Network Number), before the data recovery process is initiated, The method includes: the local MSC sends a sentlMSI request message to the HLR; after receiving the request message, the HLR returns a sentlMSI response message to the local MSC, and carries the IMSI corresponding to the MSISDN number of the calling user in the response message (International Mobile Subscriber Identity, International Mobile subscriber identity) After receiving the IMSI, the local MSC initiates a data recovery procedure to the HLR.

Step 103: The local MSC constructs an originating call message according to the acquired data of the calling user, and then simulates a call initiated by the calling user to the called user according to the originating call message.

The details are as follows: The MSC configures the CM_SERVICE_REQUEST (Connection Management Service Request) message according to the obtained data, changes the status of the calling user to the active state, and identifies the current call of the calling user as an analog call, preventing the main call from being affected. The user is called to initiate a real call, and then the calling party is simulated to initiate a call to the called user. The CM_SERVICE_REQUEST message is the originating call message.

Further, after the local MSC obtains the data of the calling user in step 102, the data may be backed up, for example, the acquired data of the calling user is backed up to a temporary database, and is not saved in the VLR, thereby avoiding the initiation by the real user. The call is affected. Correspondingly, in step 103, the process in which the local MSC simulates the calling user to initiate a call is as follows: The local MSC reads the data of the calling user from the temporary database for backup, according to the data of the called calling user. Construct a CM_SERVICE_REQUEST message, change the status of the calling user in the backed up data to the active state, and then simulate the calling user to initiate a call to the called user. In the process of simulating a call, unlike the existing real call, the MSC obtains the calling user data through the SIFOC (Send Information For Outgoing Call) message to the temporary database instead of the VLR. Get the data in .

Step 104: Determine whether the called user is in the local office. If yes, go to step 105; otherwise, go to step 108. Step 105: Determine whether the local office is abnormal. If yes, go to step 106; otherwise, go to step 107.

Step 106: It is determined that the current simulated call fails, and the local MSC directly returns a fault response message to the network management station/client, reports the abnormality information of the local MSC, and then ends.

The internal MSC abnormality may be data failure, or the calling user subscribes to a special service to release the call, for example, the operator has established a service code or set roaming restrictions.

Step 107: It is determined that the current simulated call of the local MSC is successful, and then ends.

Step 108: At this time, the called user is in the back office MSCb of the local office, first judge whether the local office is abnormal, and if yes, execute step 109; otherwise, execute step 110.

Step 109: It is determined that the current simulated call of the local MSC fails, and then ends.

Step 110: The local MSC sends an IAM incoming message to the downstream MSCb, connects the call to the backward MSCb, and receives the response message returned by the subsequent MSCb.

The contents of the IAM incoming message signaling can be directly filled in, and the calling number, called number, OPC, DPC, and M are set by the user.

Step 111: The local MSC determines whether the backward direction is abnormal according to the received response message. If yes, step 112 is performed; otherwise, step 113 is performed.

When the backward MSCb returns a REL (Release) disconnection message to the local MSC, it indicates that an abnormality occurs in the subsequent office connection. If there are multiple subsequent stations, it indicates that at least one abnormality occurs in multiple backward offices. At this time, the operator of this office can inform the operator of the subsequent office to inform the bureau that there is no abnormal situation. Please continue to check the abnormal situation to the operator of the bureau to further determine which of the multiple backwards stations has failed; When the back office MSCb returns an ACM ringing message and an ANM response message to the MSC, it indicates that the backward station continues to be normal.

Step 112: It is determined that the current simulated call of the local MSC fails, and the local MSC returns a fault response message to the network management station/client, reports the abnormality to the office after the report, and then ends.

The fault response message returned by the local MSC to the network management station/client in steps 106 and 112 can be defined by the operator. The message can carry information such as the local fault or the backward fault and the fault cause value.

Step 113: It is determined that the current simulated call of the local MSC is successful. Further, the local MSC can connect the monitoring telephone to the called user, and then ends. By monitoring the phone, the operator can talk to the called user to check the quality of the call. If the call is normal, the operator can explain to the called user that it is currently a test call.

In this embodiment, the data of the calling user is obtained through the local office, and the calling user is initiated the call according to the data. When an abnormality occurs in any one of the offices passing the call, the call is determined to be failed. When all the stations passing the call are normal, Then the call is determined to be successful. When the analog call is used to locate a call fault, it can simulate the real situation of the user's fault, and combine with the incoming incoming analog call to locate the fault. It is not necessary to specifically initiate a test call to locate the fault, which saves cost and shortens the cost. The time to solve the problem, improve user satisfaction and fault location efficiency, and can also be used to test new services, saving maintenance costs and the cost of new business testing. Set the ID when modifying the status of the calling user, or modify the status of the calling user after backing up the data of the calling user, as much as possible to reflect the situation when the real user initiates the call, which will not affect the call of the real user, and avoid the real The user's call has an impact.

In addition, in the actual application, when the new site or the site is expanded, if the wireless side construction progress is slow, and the core network side cannot be coordinated, the initial call can be performed by using the analog call method provided in this embodiment. Avoid creating work.

Example 2

This embodiment is described by using an analog call office (hereinafter referred to as the local office) to simulate a trunk incoming call. Referring to FIG. 3, the embodiment of the present invention further provides a method for simulating a call, which specifically includes the following steps:

Step 201: The operator of the local MSCb sends a request message for simulating the incoming call to the called party to the local MSCb through the client/network management station.

The request message for simulating a relay incoming call may include a calling number, a called number, and an incoming office direction. The message may be an ISUP (ISDN User Part), a PRA, a R2, a TUP (Telephone User Part), and a BICC (Bearer Independent Call Control).

Step 202: After receiving the request message for simulating the incoming call, the local MSCb constructs an originating call message, and then simulates the incoming call to the called user according to the initial call message. Among them, the originating call message is an IAM message. In addition, the MSCb also returns a call response message to the client/network management station.

Referring to FIG. 4, further, the local MSCb can also introduce a monitoring phone during the analog call, explain to the called user that the test is currently in progress, and check whether the voice path between the local office and the called user is normal, and therefore in the analog trunk. The following steps can also be included before the incoming call is initiated:

The MSCb of the local office sends an IAM message to the PSTN to call the monitoring phone. After receiving the IAM call request message, the PSTN returns an ACM ringing message and an ANM response message to the local office. After receiving the ACM ringing message and the AM response message from the PSTN, the local office returns a response message to the network management station/client to inform the network management station/client that the monitoring phone is connected. Monitoring electricity After the call is connected, the local office continues to perform the simulated IAM incoming message, simulating the step of the trunk incoming call. In order to improve the authenticity of the test, the link signaling tracking may be performed in the process of simulating the calling user to initiate the call in the embodiment 1, and the initial address message sent by the office where the calling user is located may be tracked. When the local analog trunk incoming call is initiated, the initial address message sent by the office where the calling user is located may be received, and the initial address message is used as an initial address message for relaying the incoming call to perform an analog call.

Step 203: In the process of simulating a relay incoming call, determine whether the local office is abnormal. If yes, perform the step.

204; Otherwise, go to step 205.

Step 204: It is determined that the current incoming MSCb call of the local MSCb fails, and the MSCb directly returns a fault response message to the network management station/client, reports the abnormality information of the local office, and then ends.

Step 205: The local MSCb sends an IAM incoming message to the downstream MSCb', and connects the call to the backward office.

MSCb'.

Step 206: The local MSCb receives the response message returned to the office.

Step 207: The local MSCb determines whether there is an abnormality in the backward office according to the received response message. If yes, step 208 is performed; otherwise, step 209 is performed.

Step 208: It is determined that the current simulated incoming call of the local office fails, and the local office returns a fault response message to the network management station/client, and reports the abnormality to the office after the report, and then ends.

If the called user is in the back office MSCb', that is, there is only one back office in the local office, the fault can be directly located in the back office MSCb'. If there are multiple back office in the local office, the backward office MSCb The returned response message cannot locate which back office has failed. Further, the operator of the local office can notify the backward office MSCb' to continue to simulate the incoming incoming call, so as to continue troubleshooting the call failure. The process of initiating a relay incoming call by the MSCb' is the same as that in the embodiment, and is not described here.

For example, after the MSC in Beijing receives a user complaint, the operator initiates a call through a simulated complaint to locate the fault. If the Beijing office is normal, the operator will notify the MSC of the Tianjin Bureau of the fault location after the notification. The operator of the bureau passes the simulation. After the incoming call is initiated, it is detected whether the Tianjin Bureau or another office has a fault. If another office fails, the other office is notified to continue the fault location.

Step 209: It is determined that the currently simulated relay incoming call of the local office is successful. Further, the local MSCb can connect the monitoring telephone to the called user, and then ends.

By monitoring the phone, the operator of the office can talk to the called party to check the quality of the call. If the call is normal, the operator can explain to the called user that it is currently a test call.

Further, in order not to affect the CDRs of the real user, the calling number in the calling CDR may be set by the operator or set by the system to test the MSC number of the MSC; in order not to affect the CDR of the backward office, the interoffice IAM message also may Fill in the number set by the operator or set by the system to test the MSC number of the MSC. During the analog call, if the calling user or the called user is a smart user, the system can control not to trigger the intelligent service, so that the user will not be deducted. If an analog call is made to test the smart service, the MSC needs to fill in the duration of the ACR (Apply Charging Report) reported to the SCP (Service Control Point) in the process of simulating the call. The SCP is not charged. After the SCP receives the ACR and reads the ACR for 0, the current analog call is not charged.

In this embodiment, a call is initiated by the analog trunk in the local office, which can simulate the real situation of the user when the fault occurs, and can solve the problem of the remote complaint when the fault is located, and remotely locate the fault and return the result to the user fault claim place, saving Cost, shortened the time to solve problems, improved user satisfaction and fault location efficiency, and can also be used to test new services, saving maintenance costs and the cost of new business testing. Sending an analog call through the initial address message tracked by the link signaling can improve the authenticity of the simulation.
