By routing to the MCRS 290, a line is formed between the calling terminal 200 and the called terminal 270 through the MCRS (290).

Hereinafter, a method of recording an incoming call of a called subscriber according to an embodiment of the present invention will be described with reference to the accompanying drawings.

First, a method of recording an incoming call of a called subscriber according to a first embodiment of the present invention will be described with reference to FIGS. 1 to 4.

In the first embodiment of the present invention, when a call is generated to a called terminal of a called subscriber subscribed to an incoming call recording service (hereinafter referred to as 'MCRS service'), the called HLR determines whether the called subscriber is an MCRS service registrant, In the case of the service registrant, the routing is performed to the MCRS first to connect the circuit, and then the MCRS is set to the called subscriber again so that all the contents of the call with the called subscriber are recorded.

A first embodiment of the present invention describes a case where a mobile communication subscriber records a call coming from a mobile communication subscriber and a case where the mobile communication subscriber records a call coming from a wired subscriber.

First, a case in which a mobile communication subscriber records a call received from a mobile communication subscriber will be described with reference to FIGS. 1 and 3.

When the calling subscriber whose location is registered in the calling MSC 120 attempts to make an outgoing call to his calling terminal 100, the calling MSC 120 calls the incoming information request signal (LOCREQ), hereinafter to route to the called subscriber. 'LOCREQ' is transmitted to the destination HLR 150 (step a1).

The destination HLR 150 determines whether the recipient subscriber's MCRS service is ACT / DACT, and when the recipient subscriber is an MCRS service registered subscriber, the MCRS (190) in the routing digits of the message return response message (locreq RETURN RESULT) message. Including the MCRS Number (hereinafter referred to as 'MCRSN') that is routed to the information transmitted to the originating MSC (120) (b1).

Next, the originating MSC 120 is referred to as an Initial Address Message (IAM, hereinafter 'IAM') including the MCRSN and the CDN to the MCRS 190 through the adjacent MSC 180 to which the MCRS 190 is connected. (Step c1), the MCRS 190 sends an IAM including a specific prefix (Prefix: PFX, hereinafter referred to as 'PFX') and a CDN to out-dialing to the destination MSC 140; 180) (d1 step).

The neighboring MSC 180, which has received the IAM including the specific PFX from the MCRS 190, recognizes the incoming MCRS service and indicates the MCRS service ACT in the termination access type parameter to include in the LOCREQ message. (Step e1).

When the Termination Access Type parameter is set in the received LOCREQ message, the destination HLR 150 uses the pre-registered destination information, that is, the location information of the destination number, to the destination MSC 140 where the destination subscriber is located. A routing request signal (ROUTREQ, hereinafter referred to as 'ROUTREQ') for requesting routing information about the UE is transmitted (step f1).

Next, the destination MSC 140 receiving the ROUTREQ message sends a routing response signal including a called party identification number (Temporary Local Directory Number: TLDN, hereinafter referred to as 'TLDN') including routing information about the called party. Transmitting to the destination HLR 150 (step g1), the destination HLR 150 transmits an incoming information response signal (locreq) including the TLDN received from the destination MSC 140 to the neighbor MSC 180 (step h1). .

As such, when the neighboring MSC 180, which has received routing information to the destination MSC 140 via the destination HLR 150, delivers the IAM message to the destination MSC 140, the destination MSC 140 receives the destination BS 160. Paging for the called terminal 170 is started through step (i1).

Next, the receiving MSC 140, which has received a response from the terminal 170 of the called subscriber, transmits an address complete message (ACM, hereinafter referred to as 'ACM') to the MCRS 190 through the neighbor MSC 180. (Step j1, k1), the MCRS 190 transmits the corresponding ACM to the originating MSC 120 through the neighbor MSC (180).

On the other hand, when the destination MSC 140 receives a connection message indicating that the called party requests to connect to the incoming call, the destination MSC 140 sends a response message (ANM, hereinafter referred to as 'ANM') to the neighbor MSC 180. In step (m1, n1), the MCRS 190 transmits the corresponding ANM to the originating MSC (120) through the neighbor MSC (180) (step o1).

When the originating MSC 120 transmits a connection message to the calling terminal 100 when the ANM is received, a call path is formed between the calling terminal 100 and the called terminal 170 to establish a voice call between the calling subscriber and the called subscriber. Can be done. At this time, the formed call is the originating terminal 100, the originating BS (110), the originating MSC (120), the neighboring MSC (180), the MCRS (190), the destination MSC (140), the destination BS (160) And the called terminal 170, the MCRS 190 is located between the calling terminal 100 and the called terminal 170 to make an incoming call performed between the calling terminal 100 and the called terminal 170. You can record.

As such, when the calling subscriber terminates the call while the voice call is being performed between the calling subscriber and the called party, a release (Release: REL, hereinafter 'REL') message is sent from the calling terminal 100 to the calling MSC 120. The outgoing MSC 120 transmits the REL message to the MCRS 190 via the neighboring MSC 180 to drop the outgoing call (step p1).

Next, the MCRS 190 transmits a Release Complete (RLC) message to the neighbor MSC 180 in response to the REL message and breaks the destination path to the neighbor MSC 180 (q1). step).

Thereafter, when the MCRS 190 transmits a REL message to the destination MSC 140 through the neighbor MSC 180 to terminate the call with the destination MCS 140 (step r1, s1), the destination MSC 140 In response to this, the RLC message is transmitted to the MCRS 190 through the neighbor MSC 180 to disconnect the call formed between the MCRS 190 and the destination MSC 140 (steps t1 and u1). At this time, the neighbor MSC 180 transmits the RLC message to the originating MSC 120 in response to the REL message received in step p1, so that a call formed between the originating MSC 120 and the neighbor MSC 180 is also disconnected. (u1 step).

Next, a case in which a mobile communication subscriber records a call received from a wired subscriber will be described with reference to FIGS. 2 and 4.

When a wired subscriber connected to another provider network such as PSTN 210 attempts an outgoing call to originating terminal 200, IAM is transmitted from PSTN 210 to PGS 220 (step a2).

The PGS 220 sends a LOCREQ message to the destination HLR 250 to route to the destination subscriber (step b2), and the destination HLR 250 determines whether the recipient subscriber's MCRS service is ACT / DACT, and the recipient subscriber receives the MCRS. In the case of the service registration subscriber, the MCRSN, which is information routed to the MCRS 290, is included in RoutingDigits of the locreq RETURN RESULT message and transmitted to the PGS 220 (step c2).

Next, the PGS 220 transmits the IAM including the MCRSN and the CDN to the MCRS 290 through the adjacent MSC 280 to which the MCRS 290 is connected (step d2), and the MCRS 290 receives the incoming MSC ( In step 140, an IAM including a specific PFX and CDN is delivered to an adjacent MSC 280 for out-dialing.

The neighbor MSC 280 that received the IAM including the specific PFX from the MCRS 290 recognizes the incoming MCRS service and indicates the MCRS service ACT in the Termination Access Type parameter to include in the LOCREQ message and transmits it to the destination HLR 250 ( step f2).

When the Termination Access Type parameter is set in the received LOCREQ message, the destination HLR 250 uses the pre-registered destination information, that is, the location information of the destination number, to the destination MSC 240 where the destination subscriber is located. Send a ROUTREQ message requesting routing information for (step g2).

Next, the receiving MSC 240 receiving the ROUTREQ message sends a routreq message including the TLDN including routing information for the called subscriber to the destination HLR 250 (step h2), and the destination HLR 250 receives the MSC. The locreq message including the TLDN received from the 240 is transmitted to the neighbor MSC 280 (step i2).

As such, when the neighboring MSC 280, which has received the routing information to the destination MSC 240 via the destination HLR 250, delivers the IAM message to the destination MSC 240, the destination MSC 240 is the destination BS 260. Paging is started for the called terminal 270 via step (j2).

Next, the receiving MSC 240 receiving the response from the terminal 270 of the called subscriber transmits the ACM to the MCRS 290 through the neighboring MSC 280 (steps k2 and l2), and the MCRS 290 transmits the neighboring MSC ( 280) and the corresponding ACM is transmitted to the third-party vendor network 210 through the PGS 220 (m2 step).

On the other hand, when the destination MSC 240 receives a connection message indicating that the called party requests to connect to the incoming call, the destination MSC 240 transmits the ANM to the MCRS 290 through the neighbor MSC 280 (n2, o2). Step), the MCRS 290 transmits the ANM to the third-party vendor network 210 through the neighbor MSC 280 and the PGS 220 (p2 step).

The third-party vendor network 210 transmits a connection message to the calling terminal 200 when an ANM is received, thereby forming a call path between the calling terminal 200 and the called terminal 270, thereby making a voice call between the calling subscriber and the called subscriber. Can be made. In this case, the formed call includes the calling terminal 200, the third party network 210, the PGS 220, the adjacent MSC 280, the MCRS 290, the called MSC 240, the called side BS 260 and As formed by the called terminal 270, the MCRS 290 is located between the calling terminal 200 and the called terminal 270 to record an incoming call performed between the calling terminal 200 and the called terminal 270. You can do it.

Meanwhile, the process of disconnecting a call formed between the calling subscriber and the wired subscriber by ending the call while the voice call is performed between the calling subscriber and the wired subscriber is made in the process described in FIG. 3 (p1 to u1). When the PGS 220 and the third party network 210 is replaced with the operation instead of the MSC 120, the operation is very similar, so for convenience of explanation, the description of FIG. Will be.

As described above, when a call is generated to a called terminal of a called subscriber subscribed to the MCRS service according to the first embodiment of the present invention, the called HLR determines whether the called subscriber is an MCRS service registrant, and is an MCRS service registrant. New parameters are added to the Mobile Application Protocol (MAP) message of the conventional IS-41 by routing the circuit first to the MCRS, connecting the circuit, and then setting up the circuit from the MCRS to the destination subscriber so that all the conversations with the destination subscriber are recorded. By adding new bays, existing call flow procedures can be used.

In this case, the incoming HLR adds the ability to include the MCRSN prefix in the new parameter when sending a locreq RETRUN RESULT message, and the neighboring MSC uses the specific PFX in front of the called party for each IAM received from the originating MSC or PGS and the destination MSC. Added the function of performing call processing by distinguishing, and the function of performing call processing by distinguishing through Termination Access Type parameter when processing each LOCREQ message received from incoming HLR originating MSC or PGS and neighbor MSC. Just do it.

Next, a method of recording an incoming call of a called subscriber according to a second embodiment of the present invention will be described with reference to FIGS. 1 and 2 and 5 and 6.

In the second embodiment of the present invention, when a call is generated to a called terminal of a called subscriber subscribed to the MCRS service, the called MSC checks the called subscriber's profile to determine whether the called subscriber subscribes to the MCRS service and is a MCRS service subscriber. Routing to the MCRS first to connect the line, and then set the line from the MCRS to the destination subscriber again characterized in that all the content of the call with the destination subscriber is recorded.

Also in the second embodiment of the present invention, as in the first embodiment described above, the case where the mobile subscriber records the incoming call from the mobile subscriber and the case where the mobile subscriber records the incoming call from the wired subscriber Explain.

First, a case in which a mobile communication subscriber records a call received from a mobile communication subscriber will be described with reference to FIGS. 1 and 5.

When an originating subscriber registered in the originating MSC 120 attempts to make an outgoing call to its originating terminal 100, the originating MSC 120 transmits a LOCREQ message to the destination HLR 150 for routing to the called party. (step a3).

The called party HLR 150 transmits a ROUTREQ message requesting routing information for the called party to the called MSC 140 where the called party is located by using the registered call information, that is, location information of the called number (b3). Step), when the destination MSC 140 transmits a routreq message including the TLDN including routing information for the called party to the destination HLR 150 (step c3), the destination HLR 150 receives the destination MSC 140. The locreq message including the TLDN received from the transmission is transmitted to the originating MSC 120 (d3).

As such, when the originating MSC 120, which has received routing information to the destination MSC 140 via the destination HLR 150, transmits the IAM to the destination MSC 140 (step e3), the destination MSC 140 receives the destination subscriber's information. The MCRS service ACT / DACT is determined through the profile (step f3), and when the called subscriber is the MCRS service ACT, the IMS including the MCRSN and the CDN is transmitted to the MCRS 190 through the neighbor MSC 180 (step g3). ). At this time, the destination MSC 140 transmits a registration notification (REGNOT) requesting location registration to the destination HLR 150 in the registration process of the destination subscriber before the call is received, and then registers the location at the destination HLR 150. The MCRSN for routing to the MCRS 190 included in the profile of the regnot RETURN RESULT message indicating the result is received in advance and stored.

Next, the MCRS 190 includes the TLDN in the IAM message to establish a call with the called subscriber, out-dialing to the called MSC 140 through the neighbor MSC 180 (step h3), and the called MSC 140 If it is not the first TLDN value received through the CNT information of the TLDN included in the received IAM, paging is started to the called subscriber.

Next, the incoming MSC 140 receiving the response from the terminal 170 of the called subscriber transmits the ACM to the MCRS 190 through the neighbor MSC 180 (step i3), and the MCRS 190 sends the neighbor MSC 180 to the neighbor MSC 180. And transmits the corresponding ACM to the originating MSC 120 through the terminating MSC 140 (step j3).

On the other hand, when a connection message is received at the destination MSC 140 that the called subscriber requests to connect to the incoming call, the destination MSC 140 transmits the ANM to the MCRS 190 via the neighbor MSC 180 (step k3). The MCRS 190 transmits the corresponding ANM to the originating MSC 120 through the neighbor MSC 180 and the destination MSC 140 (step l3).

When the originating MSC 120 transmits a connection message to the calling terminal 100 when the ANM is received, a call path is formed between the calling terminal 100 and the called terminal 170 to establish a voice call between the calling subscriber and the called subscriber. Can be done. In this case, the formed call includes the calling terminal 100, the calling MSC 120, the called MSC 140, the adjacent MSC 180, the MCRS 190, the called MSC 140, the called BS 160, and As formed by the called terminal 170, the MCRS 190 is located between the calling terminal 100 and the called terminal 170 to make an incoming call performed between the calling terminal 100 and the called terminal 170. You can record.

As such, when the calling subscriber terminates the call while the voice call is performed between the calling subscriber and the called subscriber, a REL message is transmitted from the calling terminal 100 to the calling MSC 120, and the calling MSC 120 sends the calling call. In order to disconnect, the REL message is transmitted to the MCRS 190 through the destination MSC 140 and the neighbor MSC 180 (m3 step).

Next, the MCRS 190 transmits the RLC message to the destination MSC 140 through the neighbor MSC 180 in response to the REL message to break the destination path from the originating MSC 180 (step n3).

Thereafter, the MCRS 190 transmits a REL message to the destination MSC 140 through the neighbor MSC 180 (step o3) in order to hang up the call with the destination MCS 140. In response, the RLC message is transmitted to the MCRS 190 through the neighbor MSC 180, thereby disconnecting the call formed between the MCRS 190 and the destination MSC 140 (p3). At this time, the incoming MSC 180 transmits the RLC message to the originating MSC 120 in response to the REL message received in step m3, thereby disconnecting the call formed between the originating MSC 120 and the destination MSC 140. (p3 step).

Next, a case in which a mobile communication subscriber records a call received from a wired subscriber will be described with reference to FIGS. 2 and 6.

When a wired subscriber connected to another provider network such as PSTN 210 attempts an outgoing call to originating terminal 200, IAM is transmitted from PSTN 210 to PGS 220 (step a4).

The PGS 220 transmits a LOCREQ message to the destination HLR 250 to route to the destination subscriber (step b4), and the destination HLR 250 uses the previously registered destination information, that is, location information of the destination number. The ROUTREQ message requesting routing information for the called subscriber is transmitted to the called MSC 240 where the subscriber is located (step c4).

The destination MSC 240 sends a routreq message containing the TLDN including routing information for the called party to the destination HLR 250 (step d4), and the destination HLR 250 receives the TLDN received from the destination MSC 240. A locreq message including a is transmitted to the PGS 220 (step e4).

As such, when the PGS 220 that has received routing information to the destination MSC 240 through the destination HLR 250 transmits the IAM to the destination MSC 240 (step f4), the destination MSC 240 receives the profile of the destination subscriber. Determining the MCRS service ACT / DACT through (g4 step), if the called subscriber is the MCRS service ACT, and delivers the IAM including the MCRSN and CDN to the MCRS 290 through the neighbor MSC (280) (step h4) . At this time, the destination MSC 240 transmits a REGNOT message for requesting location registration to the destination HLR 250 in the location registration process of the destination subscriber before the call is received, and then regnot RETURN for notifying the location registration result at the destination HLR 250. The MCRSN for routing to the MCRS 290 included in the profile of the RESULT message is received in advance and stored.

Next, the MCRS 290 includes the TLDN in the IAM message to establish a call with the called party, out-dialing to the destination MSC 240 through the neighbor MSC 280 (step i4), and the called MSC 240 If it is not the first TLDN value received through the CNT information of the TLDN included in the received IAM, paging is started to the called subscriber.

Next, the receiving MSC 240 receiving the response from the terminal 270 of the called subscriber transmits the ACM to the MCRS 290 through the neighboring MSC 280 (step j4), and the MCRS 290 sends the neighboring MSC 280. The ACM transmits the corresponding ACM to the third-party provider network 210 through the incoming MSC 240 and the PGS 220 (step k4).

On the other hand, when a connection message is received at the destination MSC 240 that the called party requests to connect to the incoming call, the destination MSC 240 transmits the ANM to the MCRS 290 through the neighbor MSC 280 (step l4). The MCRS 290 transmits the corresponding ANM to the third party network 210 through the neighbor MSC 280, the destination MSC 240, and the PGS 220 (m4 step).

The third-party vendor network 210 transmits a connection message to the calling terminal 200 when an ANM is received, thereby forming a call path between the calling terminal 200 and the called terminal 270, thereby making a voice call between the calling subscriber and the called subscriber. Can be made. At this time, the formed call is the originating terminal 200, third party network 210, PGS 220, destination MSC 240, adjacent MSC 280, MCRS (290), destination MSC 240, incoming As formed by the side BS 260 and the called terminal 270, the MCRS 290 is located between the calling terminal 200 and the called terminal 270 and is located between the calling terminal 200 and the called terminal 270. You can record incoming calls as they are made.

Meanwhile, the process of disconnecting a call formed between the wired subscriber and the called subscriber by ending the call while the voice call is being performed between the wired subscriber and the called subscriber is performed in the process described in FIG. 5 (m3 to p3). When the PGS 220 and the third party network 210 is replaced with the operation instead of the MSC 120, the operation is very similar, so for convenience of description, the description of FIG. Will be.

As described above, when a call is generated to the called terminal of the called subscriber subscribed to the MCRS service according to the second embodiment of the present invention, the called MSC checks the called subscriber profile to determine whether the called subscriber subscribes to the MCRS service. In the case of MCRS service subscribers, routing to MCRS is performed first, and then the line is connected. Then, MCRS sets up a line as a called subscriber so that all the contents of the call with the called subscriber are recorded. By adding new parameters only, existing call flow procedures can be used.

In this case, in the incoming MSC, the function of checking whether or not the subscriber is an MCRS service subscriber is added, and in the incoming HLR, the function of including the MCRSN prefix in the new parameter when transmitting a regnot RETURN RESULT message is added to the conventional system. do.

Next, a method of recording an incoming call of a called subscriber according to a third embodiment of the present invention will be described with reference to FIGS. 1 and 2 and 7 and 8.

According to the third embodiment of the present invention, when a call is generated to a called terminal of a called subscriber subscribed to the MCRS service, the called MSC checks the called subscriber's profile to determine whether the called subscriber subscribes to the MCRS service and is a MCRS service subscriber. By setting a line between the MCRS and the called subscriber through a call mixer, all the contents of the called subscriber are recorded.

In the third embodiment of the present invention, as in the first and second embodiments described above, the mobile subscriber records the incoming call from the mobile subscriber and the mobile subscriber receives the incoming call from the wired subscriber. Explain when recording.

First, a case in which a mobile communication subscriber records a call received from a mobile communication subscriber will be described with reference to FIGS. 1 and 7.

When an originating subscriber registered with the originating MSC 120 attempts to make an outgoing call to its originating terminal 100, the originating MSC 120 sends the TLDN from the terminating HLR 150 via the LOCREQ message to route to the called party. Get the value (steps a5, b5, c5, d5).

Next, the originating MSC 120 transmits the IAM to the destination MSC 140 (step e5), and the destination MSC 140 determines the MCRS service ACT / DACT based on the profile of the called party (step f5). If the MCRS service ACT is, through the neighbor MSC (180) to the MCRS 190 and delivers the IAM including the MCRSN and CDN at the same time to deliver the paging to the terminal subscribers (g5 step). At this time, the destination MSC 140 transmits a REGNOT message requesting location registration to the destination HLR 150 in the registration process of the destination subscriber before the call is received, and then regnot RETURN notifying the location registration result from the destination HLR 150. The MCRSN for routing to the MCRS 190 included in the profile of the RESULT message is received in advance and stored.

Next, the MCRS 190 receiving the IAM from the destination MSC 140 transmits the ACM to the destination MSC 140 (step h5), and the destination MSC 140 receives the IAM from the MCRS 190 and paging from the destination subscriber. When receiving a response to step (i5), the ACM is forwarded to the originating MSC (120) (step j5).

Meanwhile, the MCRS 190 transmits the ANM to the originating MSC 120 through the neighbor MSC 180 and the destination MSC 140 (step k5).

When the originating MSC 120 transmits a connection message to the calling terminal 100 when the ANM is received, a call path is formed between the calling terminal 100 and the called terminal 170 to establish a voice call between the calling subscriber and the called subscriber. Can be done. At this time, the called MSC 140 mixes the call between the MCRS 190 and the called subscriber by using the call mixer function so that the contents of the call pass through the MCRS 190 during the incoming call. Calls formed here include the originating terminal 100, the originating MSC 120, the terminating MSC 140, the neighboring MSC 180, the MCRS 190, the terminating MSC 140, the terminating BS 160 and the terminating terminal. As formed by the 170, the MCRS 190 may be located between the calling terminal 100 and the called terminal 170 to record an incoming call performed between the calling terminal 100 and the called terminal 170. Will be.

As such, when the calling subscriber terminates the call while the voice call is performed between the calling subscriber and the called subscriber, a REL message is transmitted from the calling terminal 100 to the calling MSC 120, and the calling MSC 120 sends the calling call. In order to disconnect, the REL message is transmitted to the MCRS 190 through the terminating MSC 140 and the neighboring MSC 180 (step l5).

Next, the MCRS 190 breaks the incoming path by transmitting the RLC message to the originating MSC 120 through the neighbor MSC 180 and the destination MSC 140 in response to the REL message (step m5).

Next, a case in which a mobile communication subscriber records a call received from a wired subscriber will be described with reference to FIGS. 2 and 8.

When a wired subscriber connected to another provider network such as PSTN 210 attempts an outgoing call to originating terminal 200, IAM is transmitted from PSTN 210 to PGS 220 (step a4).

Then, when the PGS 220 transmits a LOCREQ message to the destination HLR 250 for routing to the called subscriber, the MCRS 290 sends the ANM through the neighbor MSC 280 and the destination MSC 240 to the third party. Processes (b6 to l6) up to the step of transmitting to the network 210 is very similar to the processes (a5 to m5) in the embodiment described with reference to FIG. 7, and thus omitted for convenience of description, FIGS. 4 and 7 Reference will readily be made by those skilled in the art to which reference is made. Here, only the operation of the third-party vendor network 210 and the PGS 220 in place of the originating MSC 120 in FIG. 7 is different, and this part is fully described in FIG. 4 above.

On the other hand, for the call termination process between the wired subscriber and the called subscriber, the PGS 220 and the third party network 210 operate in place of the originating MSC 120 in the process described in FIG. 7 (steps l5 and m5). In case of replacement, the operation is very similar, so for convenience of description, the description of FIG. 7 will be easily understood by those skilled in the art, even if omitted.

As described above, when a call is generated to the called terminal of the called subscriber subscribed to the MCRS service according to the third embodiment of the present invention, the called MSC checks the called subscriber profile to determine whether the called subscriber subscribes to the MCRS service. In the case of MCRS service subscribers, the MCRS and the called subscribers are set up through a call mixer to record all the calls made by the called subscribers, thereby adding only new parameters to the conventional IS-41 MAP message. The existing call flow procedure can be used.

In this case, the incoming MSC adds a function to check whether or not it is an MCRS service subscriber when processing all calls, the incoming HLR adds a function to include MCRSN prefix in a new parameter when sending a regnot RETURN RESULT message, and also in the incoming MSC The function of mixing the MCRS with the called subscriber by using the call mixer function only needs to be added to the conventional system.

Next, a method of recording an incoming call of a called subscriber according to a fourth embodiment of the present invention will be described with reference to FIGS. 1 and 2 and 9 and 10.

In the fourth embodiment of the present invention, when a call is generated to a called terminal of a called subscriber subscribed to the MCRS service, the called HLR determines whether the called subscriber is an MCRS service registrant, and if it is an MCRS service registrant, routing to MCRS first. After the line is connected, the MCRS sets the line back to the called subscriber so that all the contents of the call with the called subscriber are recorded.

In the fourth embodiment of the present invention, as in the first to third embodiments described above, when the mobile subscriber records the incoming call from the mobile subscriber and the mobile subscriber receives the incoming call from the wired subscriber, Explain when recording.

First, a case in which a mobile communication subscriber records a call received from a mobile communication subscriber will be described with reference to FIGS. 1 and 9.

When an originating subscriber registered in the originating MSC 120 attempts to make an outgoing call to its originating terminal 100, the originating MSC 120 transmits a LOCREQ message to the destination HLR 150 for routing to the called party. (step a7).

The called party HLR 150 transmits a ROUTREQ message requesting routing information for the called party to the called MSC 140 where the called party is located by using the registered call information, that is, location information of the called number (b7). Step), the destination MSC 140 transmits a routreq message including the TLDN including routing information for the called party to the destination HLR 150 (step c7).

Next, the destination HLR 150 transmits a locreq message including the TLDN and MCRSN received from the destination MSC 140 to the originating MSC 120 (step d7).

The originating MSC 120 transmits the IAM including the MCRSN and TLDN to the MCRS 190 via the neighbor MSC 180 (step e7), and the MCRS 190 receives the MSC 140 through the neighbor MSC 180. Forwards the IAM with the TLDN (step f7).

As such, the receiving MSC 140 receiving the IAM message including the TLDN from the MCRS 190 starts paging for the called terminal 170.

Next, the receiving MSC 140 receiving the response from the terminal 170 of the called subscriber transmits the ACM to the MCRS 190 through the neighbor MSC 180 (step g7), and the MCRS 190 sends the neighbor MSC 180. The ACM is transmitted to the originating MSC 120 through (step h7).

On the other hand, when a connection message is received at the destination MSC 140 that the called party requests to connect to the incoming call, the destination MSC 140 transmits the ANM to the MCRS 190 via the neighbor MSC 180 (step i7). The MCRS 190 transmits the corresponding ANM to the originating MSC 120 through the neighbor MSC 180 (step j7).

When the originating MSC 120 transmits a connection message to the calling terminal 100 when the ANM is received, a call path is formed between the calling terminal 100 and the called terminal 170 to establish a voice call between the calling subscriber and the called subscriber. Can be done. At this time, the formed call is the originating terminal 100, the originating BS (110), the originating MSC (120), the neighboring MSC (180), the MCRS (190), the destination MSC (140), the destination BS (160) And the called terminal 170, the MCRS 190 is located between the calling terminal 100 and the called terminal 170 to make an incoming call performed between the calling terminal 100 and the called terminal 170. You can record.

On the other hand, the process of disconnecting the call formed between the calling subscriber and the called subscriber (steps k7 to o7) during the voice call is performed between the calling subscriber and the called party (steps k7 to o7) described in FIG. To step u1), so they are omitted here.

Next, a case in which a mobile communication subscriber records an incoming call from a wired subscriber will be described with reference to FIGS. 2 and 10.

When a wired subscriber connected to a third-party provider network such as PSTN 210 attempts an outgoing call to originating terminal 200, IAM is transmitted from PSTN 210 to PGS 220 (step a8).

Thereafter, the PGS 220 transmits the LOCREQ message to the destination HLR 250 for routing to the called party, and disconnects the call path between the calling party and the called party (steps b8 to p8). Is very similar to the processes (a7 to o7) in the embodiment described with reference to FIG. 9 and will be easily understood by those skilled in the art when referring to FIGS. 4 and 9 even if omitted for convenience of description. Here, only the operation of the third-party vendor network 210 and the PGS 220 in place of the originating MSC 120 in FIG. 9 is different, and this part is fully described in FIG. 4 above.

As described above, when a call is generated to a called terminal of a called subscriber subscribed to the MCRS service according to the fourth embodiment of the present invention, the called HLR determines whether the called subscriber is an MCRS service registrant of the called subscriber, and if it is an MCRS service registrant, By routing the circuits first, connecting the circuits, and then setting up the circuits from the MCRS to the called subscribers so that all of the contents of the call with the called subscribers are recorded, thereby adding only new parameters to the MAP message of the conventional IS-41. Existing call flow procedures can be used.

In this case, in the destination HLR, the function of including the MCRSN prefix in the new parameter when transmitting the locreq RETRUN RESULT message need only be added to the conventional system.

Although the preferred embodiment of the present invention has been described in detail above, the present invention is not limited thereto, and various other changes and modifications are possible.

According to the present invention, important call contents can be preserved without a separate device.

In addition, it is possible to preserve the contents of the call without worrying about the storage space where the called subscriber stores the contents of the call.

In addition, it is possible to increase profitability by recording incoming call contents.
