Description

Method for processing flexible paging and additional service function in mobile communication system {method for processing of frexible paging and sub-service function in mobile communication system}

According to the present invention, in the case where a CDMA wireless subscriber is located in an adjacent area of a switching period (a flexible paging function performing area) and a holder of a CRBT (Color Ring Back Tone) function, flexible paging when setting an incoming call to an arbitrary subscriber Simultaneous processing of flexible paging function and color ring additional service to perform CRBT (Music Broadcasting / TONE) function to send CRBT of called subscriber instead of ring back tone to terminal of calling subscriber The method relates to a method of managing a CDMA wireless subscriber located in a hard handover area of a neighboring exchange, and more specifically, managing a flexible paging area and processing paging with two exchanges, and then responding with an actual called terminal. To perform the CRBT function as an additional service of the called party to the calling subscriber during the function of setting up a call to the exchange This is a function to allow the calling subscriber to listen to the music broadcast held by the called subscriber, and by providing the two services at the same time, the CDMA wireless subscriber can provide various and convenient additional service functions in the handover area of the exchange. The present invention relates to a method for processing flexible paging and additional service functions in a communication system.

In general, in a mobile communication system, flexible paging means that a home location register (HLR) manages a hard handoff area for two exchanges (MSC, Mobile Switching Center). RoutingRequest (requesting subscriber routing information request) is sent to send the two destination exchange information to the originating exchange, and then the call setup is performed to the exchange of the answering side of the two destination exchanges so that the call can be made. Say the function. In other words, due to the mobility of the subscriber, it is a function to increase the response rate of the called subscriber by requesting paging to both exchangers without using the hard handoff function in the adjacent area of the exchange period.

In addition, the CRBT (Color Ring Back Tone) in the mobile communication system refers to a function of listening to the calling subscriber a specific tone (tone) / music broadcast registered by the subscriber having the function. That is, it is a function of providing a caller with an arbitrary ring back tone determined by an incoming call when an arbitrary subscriber establishes a call as a function holder.

On the other hand, in the mobile communication system according to the prior art, the ringing tone / CRBT cannot be provided by the called party when the flexible function is used. In the ISUP section, when the status of the called subscriber is idle, the ACM message is transmitted before the paging response of the terminal. Therefore, the actual origin is that, even if the terminal does not respond to the paging, if the incoming is configured in the ISUP interval, the originating is determined that the incoming paging response.

That is, if the actual destination is located in the same exchange as the sender, the originating processing block receives the alerting message when the terminal transmits the paging response message to the exchange, but after checking the status of the called subscriber in the ISUP period (between the exchange period), the ACM When a message is received, an alerting message is received so that it is impossible to know which exchange is actually located at the exchange. Therefore, when the destination exchange provides ringback tones, there is a situation in which two ringback tones may be connected although one source path is connected.

At this time, if the ringback tone is provided from two incoming calls as described above, the outgoing call path and the two incoming call paths are shifted from each other.

Therefore, in case of flexible paging, the originating exchange connects the ringback tone directly at the originating side and ignores the ringback tone service provided by the called side exchange.

Therefore, the CRBT function is a service provided by the called party, so there is a problem in that the CRBT function cannot be provided in the flexible situation.

Accordingly, the present invention is proposed to solve the above problems of the prior art,

An object of the present invention is to manage a flexible paging area and to process paging with two exchanges when managing CDMA wireless subscribers located in a hard handover area in an adjacent exchange period, and then call the exchange with a response of the actual called terminal. By performing the setting function, the calling subscriber performs the CRBT function, which is an additional service of the incoming call, so that the calling subscriber can listen to the music broadcast held by the called subscriber. The present invention provides a method of processing flexible paging and additional service functions in a mobile communication system to provide various and convenient additional service functions in a handover area.

Hereinafter, a preferred embodiment of "a method of processing flexible paging and additional service functions in a mobile communication system" according to the present invention will be described in detail with reference to the accompanying drawings.

1 is a block diagram illustrating a simultaneous processing of a flexible paging function and a CRBT function in a mobile communication system according to the present invention.

As shown in the drawing, when the mobile communication terminal (calling terminal) 110 requests call origination in the region A, the first control station 120 receives the call and sends the call to the first exchange 130. Require. When the call originating request is received, the first exchange 130 requests the originating subscriber information of the mobile communication terminal 110 to a first visitor location register (hereinafter, abbreviated as "VLR") 140. When the originating subscriber information response is received from the first VLR 140, a call location and call setup information is requested to a home location register (hereinafter abbreviated as "HLR") 400.

In response to the call location and call setup information request from the first exchange 130, the HLR 400 sets an incoming call to the VLRs 240 and 340 in the adjacent areas (area B, area 200, and area C 300). You will be asked for information.

Thereafter, when a response to the incoming call setup information is received from the second and third VLRs 240 and 340, the destination location and the call setup information response are transmitted to the first exchange 130.

Upon receiving the response, the first exchange 130 requests the incoming and outgoing call setup from the second and third exchanges 230 and 330. The second and third exchangers 230 and 330 that receive the request request the information of the called subscriber to each of the VLRs 240 and 340 in the region, and request the called subscriber information from the corresponding VLR 240 and 340. When a response to the call is received, each control station 220 or 320 in the region transmits a call to the called subscriber and a response to the call setup to the first exchange 130.

Meanwhile, the second and third control stations 220 and 320 that receive the called party call request from each of the corresponding exchanges 230 and 330 make the called party call to the mobile communication terminal 210 and 310. FIG. send.

At this time, when there is a response to the called party call from the second mobile communication terminal 210, the second control station 220 sends the incoming response from the second mobile communication terminal 210 to the second switch 230. (Here, it is assumed that the terminal corresponding to the call setup request from the first mobile communication terminal 110 has a response from the second mobile communication terminal 210 in the region B).

The second exchange 230 notifies the first exchange 130 that there is an incoming response from the mobile communication terminal 210 of the region, and the first exchange 130 receives the first call completion. The control station 120 informs it.

Upon receiving the call setup completion, the first control station 120 notifies the first mobile communication terminal 110 requesting the call setup that call setup is completed.

An operation configuration for simultaneously processing a flexible paging function and an additional service (CRBT) function according to the present invention in the configuration as described above is as follows.

First, in the case of flexible paging (hereinafter, abbreviated as "FP"), since the actual called subscriber is located at one of two exchanges, the response of the called subscriber terminal may be made only at one of the two exchanges.

First, in the case of a ring back tone, when a terminal responds to paging when a paging request is made to a called subscriber, the receiving side exchange provides a tone as a path of an originating exchange. Here, since the ASUP message is transmitted before the paging response of the terminal when the called subscriber state is idle in the ISUP interval, the actual outgoing call does not respond to the paging response of the terminal. Judged that.

Second, when the actual terminal presses the SEND button for the call, the called party must disconnect the ringback tone and connect the route to the call between the called party and the called party.

As described above, in accordance with the technical principles of the present invention, as described in the first and second assumptions described above, connection from the called party to the call is performed at the paging response (the time point at which the ringback tone is connected to the called terminal) and the called party response (the caller terminal calls the call button). This is the case in two cases.

In more detail, when the originator receives the response message for the first time (for example, a paging response message in the home station, an ACM message in the ISUP interval), the originating path is connected to the FP control block at the first receiving side. To receive the ringback tone and CRBT transmitted from the destination exchange.

In addition, when receiving a response message for the second (for example, a connect message in case of own station, ANM message in case of ISUP interval), the first path is released and the second message is received. Reroute the route to an outgoing call.

In this case, when the first receiving the ringback tone receives the response message for the second, the calling party should not release the path and release the FP resources allocated for the second response message.

In addition, in case of CRBT, the called subscriber transmits a specific music broadcast or tone to the calling terminal instead of the ringback tone (RBT). Therefore, if the called party is the holder of the CRBT function, call_proc_tone / RBT is not transmitted. It provides music broadcasting (CRBT) / tone (TONE) so that the exchange of ACM sender performs CRBT function.

That is, because the calling route is already connected to the exchange that sent the ACM, the destination exchange does not provide ringback tone when the subscriber is the CRBT holder. Can be provided to the calling party.

2 is a flowchart illustrating a simultaneous processing of a flexible paging function and a CRBT function in a mobile communication system according to the present invention.

As shown in FIG. 1, a first process of requesting location and call setup information of a called party (LOCREQ) to an HLR registered by a called party, and receiving a request from a flexible paging area in the HLR receiving the request. The second process of requesting routing information to each VLR (first and second VLRs) of the neighboring area and allocating a TLDN from the VLR receiving the routing information request. Transmitting a result to the HLR, collecting the location and call setup information of the called party from the first and second VLRs in the received HLR, and transmitting the location and call setup information of the called party to the originating exchange. In the fourth process of transmitting, and if there are two terminating lists in the originating exchange, it is determined as FP, and the FP processing block is required to request FP processing to set the call to one called number transmitted in the terminating list. A fifth step of requesting FP processing to the FP processing block for another FP incoming after the request of the FP processing, and confirming the number of the called subscribers (TLDN) in the FP processing block. A seventh process of determining that the subscriber is the subscriber and requesting the incoming call setting to the incoming processing block of the third exchange; and an eighth process of requesting the incoming subscriber information from the incoming processing block to the VLR if the incoming call setting is requested; A ninth process of transmitting the called subscriber information to the called processing block at the received VLR, a tenth step of requesting paging when the called subscriber is idle with the called subscriber information in the called processing block, and the paging. An eleventh step of transmitting the ISUP message ACM to the calling exchange after the request; and the called subscriber additional service information in the called processing block receiving the called subscriber information response message; A twelfth step of requesting the CRBT function processing to the CRBT processing block, confirming that the holder is a CRBT function holder, a thirteenth step of requesting a connection from the CRBT processing block receiving the request to the CRBT server, and receiving the connection request. A 14th process of notifying the CRBT processing block that the CRBT server is connected to the CRBT processing block; and a call path of the called party by configuring a route for the call and connection with the CRBT server in the CRBT processing block; A 15th step of connecting a path to a call path and a call of the originating subscriber to the FP processing block when the incoming subscriber calling message is transmitted for the first time by determining that the notification message during the called subscriber call received in the transmitting step of the ISUP message ACM is the first; The FP processing block connects the path with the calling party, and the called subscriber transmitted from the second exchange. A 17th step of receiving a notification message during a call of the caller; and the called party transmits a called party response message to a second exchange in which the CRBT function is not currently performed, and the called processing block connects the path to the called party's call. Step 18, in the outgoing call processing block, when the incoming call outgoing notification message is the second time, the FP processing block notifies the FP processing block that it is already connected to the route; In step 20, the incoming subscriber response message is transmitted to the FP processing block, and the FP processing block transmits the incoming response message to the originating processing block, and the originating subscriber to the FP processing block occupying the call path from the originating processing block. Step 21 of transmitting the release notification message; and the FP processing block receiving the notification message is transferred to its own call. A step 22 of releasing the message, and notifying the terminating processing block of the third exchange to notify the originating subscriber release; requesting a route connection to the outgoing call to the FP processing block to which the actual terminating subscriber response message is transmitted; A twenty-third step of connecting a path to a call; and a terminating processing block of the third exchange that has received the originating subscriber release notification; a twenty-fourth step of requesting a CRBT release, releasing an allocated resource; and receiving the CRBT release request; In step 25, a CRBT processing block releases resources allocated for CRBT, requests CRBT release from the CRBT server, and the CRBT server releases allocated resources when receiving a CRBT release request.

Looking at the simultaneous processing method of the flexible paging function and the additional service (CRBT) function according to the present invention having the configuration as described above in more detail.

First, the location confirmation and call setup information (LOCREQ) of the called party is requested to the home location register (HLR) registered by the called party.

The HLR 400 determines that the called party is a flexible paging area (adjacent area of the exchange period), and requests routing information to the second VLR and the third VLR.

The VLR receiving the request for routing information allocates a TLDN (temporary number assigned by the exchange) and transmits a return result to the HLR, and the received HLR collects call location and call setup information from the two VLRs. .

The HLR also sends the collected location confirmation and call setup information of the called party to the calling exchange.

At this time, the TLDN transmitted from two VLRs is transmitted to a termination list (termination subscriber routing information) value, which is a parameter of location confirmation and call setup information (locreq) of the called subscriber, so that the call is sent to two exchanges. Allows setting to be performed.

On the other hand, the originating exchange determines that there are two called lists and determines that it is flexible paging, and requests flexible paging processing to set up a call with one called number transmitted to the called list.

At this time, the originating information (calling number, additional service information, location information) and the called number (TLDN) transmitted from the called list are transmitted from the calling processing block to the FP processing block.

Next, a flexible paging process is required for another flexible paging call, which is performed as two different incoming call processing routines as described above, and requests paging on both sides by performing call setup in two routines. Thereafter, when there is an incoming response to one FP processing block, the other routine is released.

On the other hand, the FP processing block determines the terminating subscriber's number (TLDN) to determine that the subscriber is in the third exchange area, and requests the incoming call setting to the terminating processing block of the third exchange.

Next, the called processing block receiving the request requests the called subscriber information to the VLR, and the receiving VLR sends the called subscriber information to the called processing block.

Here, the transmitted information is the actual subscriber number, location information, and additional service information of the called party, and the called processing block requests the paging when the called party is idle with the called party information.

Next, the incoming processing block sends an ISUP message ACM to the calling exchange after the paging request.

Here, the ACM is a message informing that the called party is alerting (Paging), and the FP processing block informs that the called party is calling the calling process block.

Next, the called processing block receiving the called subscriber information response message confirms that the called subscriber additional service information is a CRBT function holder, and requests the CRBT processing block to process the CRBT function.

The CRBT processing block that receives the CRBT function processing request requests a connection to a CRBT server, and the CRBT server that receives the CRBT processing block notifies the CRBT processing block that the CRBT server is connected.

The CRBT processing block that receives this connects the call path of the called party by constructing a call path for origination and connection and a call path for connection with the CRBT server.

Next, if it is determined that the notification message received during the called party is the first message, and the message of the called party is transmitted for the first time, the FP processing block requests a path connection to the call of the calling subscriber, and receives the received FP process. The block connects the route to the calling party.

At this time, since the path is connected to the called party in the CRBT processing block, when the path is connected to the calling party, the subscriber listens to a specific music broadcast registered by the called subscriber transmitted from the CRBT server.

Next, a notification message during a called destination call sent from the second exchange is received.

Thereafter, the called subscriber (receiving terminal) transmits the called subscriber response message to the second exchange in which the CRBT function is not currently performed, and the called processing block connects the path to the call of the called subscriber.

On the other hand, in the outgoing call processing block, if the incoming call outgoing notification message is the second time, the FP processing block notifies the FP processing block that the path is already connected, so that the call is not connected to the outgoing call, which is a response to receiving the notification message received from the second exchange. to be.

The incoming processing block of the second exchange receiving the response transmits the called party response message to the FP processing block, and the FP processing block transmits the incoming response message to the originating processing block.

The originating processing block receiving the response message transmits the originating subscriber release notification message to the FP processing block occupying the path of the call.

At this time, the FP processing block receiving the notification message releases the path of its own call and notifies the incoming subscriber release of the incoming processing block of the third exchange.

On the other hand, the outgoing process block requests the route connection to the outgoing call to the FP processing block to which the actual incoming subscriber response message is transmitted, and the FP processing block connects the route to the outgoing call.

Next, the incoming processing block of the third exchange that has received the originating subscriber release notification requests the CRBT release and releases the allocated resources.

Next, the CRBT processing block receiving the CRBT release request requests release of resources allocated for CRBT and CRBT release to the CRBT server, and the CRBT server releases the allocated resources upon receiving the CRBT release request.

As described above, the present invention changes the structure of the exchange to provide a Color Ring Back Tone function to a subscriber located in an area where a hard handover may occur in an adjacent exchange period (an area where a flexible paging function is performed). There is a key point about the matter.

First, when performing a flexible paging (incoming processing function to two exchanges) function, first, the paging response message (Alerting message, ISUP ACM message) of the terminal is connected to the outgoing call route to the exchange.

In this case, the called side exchange exchanges the CRBT function if the holder of the information of the called subscriber handles the CRBT function, and provides a ringback tone to the calling side path in the case of the general subscriber.

Second, when the actual called terminal responds to the call (Connect message, ISUP ANM message), the path is disconnected to the first call, and the incoming call is routed to one call.

That is, in the accompanying drawings, in Fig. 2, when the notification of the called party is called, the path is routed to an outgoing subscriber call, and when the called party responds to, the incoming response is received from the FP processing block that is currently connected to the CRBT or is received from another FP processing block. In the same case, the resource is released from the FP processing block that is not connected to the CRBT, and a call is made between the called party and the called party.

In addition, if not the same, there is a point in the configuration for requesting the release of the path to the call to the FP processing block in the CRBT connection, and rerouting to the call of the calling subscriber to the FP processing block of the receiving party response.

As described above, in the detailed description of the present invention, a specific embodiment of a method for processing flexible paging and additional service functions in a mobile communication system will be described. However, the present invention may be modified in various ways without departing from the scope of the present invention. It is possible. Therefore, the scope of the present invention should not be limited to the described embodiments, but should be determined not only by the claims below but also by the equivalents of the claims.

According to the present invention described above, "a method for processing flexible paging and additional service functions in a mobile communication system",

In case of setting up incoming call to CDMA wireless subscriber located between adjacent exchanges, paging is required for two exchange periods, and then incoming call is performed when flexible paging is connected to a call to exchange with answer. If the subscriber is a holder of an additional service (CRBT-Color Ring Back Tone) function, it has the advantage of providing the CRBT (music broadcasting or a specific tone) held by the called party to the terminal of the calling subscriber.

In addition, when performing the flexible paging function according to the prior art, since the ring back tone is transmitted from the originating party, the additional service (CRBT) function possessed by the called subscriber is specified in a specific region (hard handover region of exchange period, region performing FP function). In the present invention, the flexible paging function is performed through the management of the paging response and the response message of the called terminal in the two flexible processing blocks and the originating processing block, and the outgoing call path management. By performing the CRBT function during operation, there is an advantage that can provide a higher quality additional service to the CDMA wireless subscriber.
