Call setting processing is performed for the subscriber station 10a to be received.

Here, when a situation in which the personal communication subscriber accommodated in the personal communication exchange system cannot receive an incoming call for a predetermined period of time occurs, the calling personal communication subscriber calling the personal communication subscriber cannot know the situation of the personal communication subscriber. Therefore, as the individual communication subscribers are continuously called within the predetermined time, the corresponding personal communication exchange system is overloaded, so that the efficient exchange service cannot be performed. In this case, for the convenience of the user, the corresponding personal communication exchange system requires a predetermined service for notifying the calling personal communication subscriber that the personal communication subscriber is not in a call for a certain period of time registered by the personal communication subscriber.

It includes a CSL (Call Processing System Library) 72a-5 for interfacing with a register number.

In addition, the INS indicated by the reference numeral 78 includes an LCC (LR call control) 78a for providing data required for mobile subscriber call processing, and the LCC 78a is the PCC 72a- when the mobile subscriber makes an outgoing call. 2) If mobile subscriber information is provided or the mobile subscriber of the called party responds to paging, the mobile subscriber information of the called party becomes the call control block, and the TLDN is allocated when the mobile subscriber receives a TLDN assignment. The function will be performed. The INS 78 further includes a location register service control (LRSC) 78b which performs an operation processing procedure for the LCC 78a as a personal communication application unit (MAP), an interface between the LLU and the question-and-answer operation (TCAP); A number translation unit (NTR) for obtaining and processing information of a called party by translating an incoming / outgoing call, an incoming call while translating an international number, an area code, and a country code; Switching network control (SNC) 78D, which performs the function of assigning and releasing a call for connection / release of a call to a channel of an entire switch (T-S-T switch network) of a personal communication system; A space switch (SSW) 78e which performs a connect / disconnect request from the SNC 78d to the call; Call processing service that performs basic encoding and decoding functions of component parameters by referring to connection function with TCAP, related operation with application processor, management of instruction number and dialog number, and operation / error definition while performing operation procedure. It also includes a call processing service control (CPSC) 78f as a control means. In addition, the INS 78 is connected to the HLR 100 via a signal through the ASS-T 80 and the HLR 100 can be accessed.

In addition, reference numeral 82 shown in FIG. 3 is an ASS-GS configured to include a general fixed subscriber access, a GSC 82b for guide broadcast processing, a GSI 82c, and a TSW 82a for setting a call path. .

Subsequently, a call-inhibition processing method in the personal communication exchange system according to the present invention will be described in detail with reference to the flowchart shown in FIG.

First, when the mobile subscriber station 10a becomes the calling party and the call establishment request is delivered to the first international controller 30a, in step 94, the connection request for the call management (CM) service is transmitted from the first base station controller 30a to the SCCP. The message for the CM service request is transmitted to the PCSI 72a-1 of the ASS-W 72a of the exchange 40. Accordingly, the PCSI 72a-1 of the ASS-W 72a is transmitted. In step 96, a CM service request is forwarded to the PCC 72a-2. In response to the request, the PCC 72a-2 sends a calling party information request signal to the LCC 78a of the INS 78 in step 98. And in response to the request, the LCC 78a notifies the PCC 72a-2 of the ASS-W 72a of the calling party information, and the PCC 72a-2 that has been notified of the calling party information. In step 102, after notifying the PCSI 72a-1 of the process ID, it determines whether the authentication procedure and encryption are applied.

If it is determined that authentication and encryption are applied (YES in step 104), the PCC 72a-2 of the ASS-W 72a transmits to the LCC 78a of the INS 80 in step 106. The subscriber's authentication is required, and thus, the LCC 78a of the INS 80 requests the authentication of the calling party's personal communication subscriber to the LRSC 78b, and the ASS-T 80 at the LRSC 78b. ), The HLR is required to authenticate the calling party's personal subscriber.

In response to the authentication request, the HLR notifies the LRSC 78b of the INS 80 of the calling personal communication subscriber in step 108, and in step 110 determines whether to apply the authentication result and unique attempt. do.

As a result of the determination, if the authentication fails and the unique attempt is not applied (YES in step 112), the release command is transmitted from the PCC 72a-2 of the ASS-W 72a to the PCSI 72a-1 in step 116. Therefore, when the PCSI 72a-1 transmits a release message to the SCCP, the PCSI 72a-1 transfers a message indicating the connection rejection from the SCCP to the corresponding base station controller 30a, and terminates the call setup process.

On the other hand, if authentication fails in step 110 and the unique attempt is applied (YES in step 116), the process proceeds to step 118 where the PCSI (PCSI 72a-2) of the ASS-W 72a is used. 72a-1), and in response to the authentication request, the PCSI 72a-1 transmits a signal connection establishment message for the authentication request to the SCCP, and accordingly, the SCSI to the base station controller 30a. A connection establishment message for the authentication request is sent.

Accordingly, the base station controller 30a transmits a response message to the SCCP in step 120, and transmits an authentication response message to the PCSI 72a-1 of the ASS-W 30a in the SCCP. The PCSI 72a-1 transfers the authentication response to the PCC 72a-2.

Then, the PCC 72a-2 determines whether authentication failed in step 122, and if it is determined that the authentication fails, in step 124, the PCC 72a-2 of the ASS-W 72a receives a PCSI ( The release command is transmitted to 72a-1, and the PCSI 72a-1 transmits the release command message to the SCCP. Accordingly, the SCCP transmits a message of type 1 data on the release command to the base station controller 30a at step 126. Accordingly, the type 1 data message on completion of the release is transmitted from the base station controller 30a to the SCCP. Will be sent. Then, the SCCP forwards the released first type data message to the PCSI 72a-1 of the ASS-W 72a in step 128. Accordingly, the PCSI 72a-1 transmits the PCC 72a-2. In addition to notifying the completion of the release to send a message for the signal connection recovery (rejection) to the SCCP, and then the connection recovery message from the PCSI (72a-1) of the ASS-W (72a) to the SCCP On the other hand, after the base station controller 30a transmits a recovery completion message to the SCCP, the call setup process ends.

On the other hand, if it is determined in step 110 that the authentication succeeds and encryption is applied (YES in step 132), or in step 134, the authentication success is determined in step 134 without determining that authentication failed. If it is determined (YES in step 134), the PCC 72a-2 of the ASS-W 72a transmits an encryption command to the PCSI 72a-1 in step 136, and the PCSI 72a-1. ) Transmits an encrypted mode command message to the SCCP. Accordingly, the SCCP transmits an encrypted mode command data message to the base station controller 30a.

In response to the command, if the base station controller 30a transmits a data message indicating completion of the encryption mode to the SCCP in step 138, the SCCP sends an encryption mode to the PCSI 72a-1 of the ASS-W 72a. The PCSI 72a-1 of the ASS-W 72a notifies the PCC 72a-2 of the encryption completion in step 140.

The PCC of the ASS-W 72a when the completion of encryption is notified and when the determination result encryption step is not applied in the step 104 and when the authentication result is successful when the determination result in the step 132 is not applied. 72a-2 notifies the PCSI 72a-1 of the acceptance of the CM service in step 142, whereby the PCSI 72a-1 transmits the response of the signal connection message to the SCCP, and the SCCP. In step 144, the base station controller 30a transmits a connection establishment message.

Accordingly, the base station controller 30a transmits a message requesting call setup to the SCCP in step 146 in response to the connection establishment message. Accordingly, in the SCCP, the PCSI 72a-1 of the ASS-W 72a is transmitted. Call setup request message is transmitted to the PCC 72a-1, and the call setup message is transmitted to the PCC 72a-2.

Then, the PCC 72a-2 of the ASS-W 72a determines the availability of the lake at step 148. If the determination is not possible, the PCC 72a-2 proceeds to step 150 to the PCSI 72a-1. The connection recovery command is transmitted, and the PCSI 72a-1 transmits a connection recovery (release) command message to the SCCP, and then the SCCP transmits a release completion command message to the base station controller 30a.

Then, in the PCC 72a-2 of the ASS-W 72a, when the release command is transmitted to the step PCSI 72a-1, the PCSI 72a-1 transfers the release command message to the SCCP. The SCCP transmits a release command message to the base station controller 30a.

In response to the release command message, the base station controller 30a transmits a release completion message to the SCCP in step 154. The SCCP receiving the release completion message transmits the PCSI 72a-1 of the ASS-W 30a. The PCSI 72a-1 notifies the PCC 72a-2 of the release completion and transmits the release message to the SCCP.

Then, the SCCP transmits a recovery message to the base station controller 30a in step 156, and the base station controller 30a transmits a recovery completion message to the SCCP in step 158 to complete call release.

On the other hand, if the result of the determination in step 148 is possible, the flow proceeds to step 160 and the PCC 72a-2 of the ASS-W 30a transmits the personal communication to the LCC 78a of the INS 80. In step 162, the LCC 78a of the INS 80 notifies the PCC 72a-2 of the ASS-W 72a of the calling personal communication subscriber. In step 164, the PCC 72a-2 registers the call setup state of the subscriber station 10a as a calling party to the LCC 78a of the INS 80 and sets up a call to the PCSI 72a-1. You will be informed of the process.

Then, in step 166, the PCSI 72a-1 of the ASS-W 72a transmits a call setup process message to the SCCP, and the SCCP transmits a call setup process message to the base station controller 30a. In addition, in the PCC 72a-2 of the ASS-W 72a, when the PCSI 72a-1 receives a command for setting a call path in step 168, the PCSI 72a-2 receives the PCSI.

In 72a-1, the call setup command request message is transmitted to the SCCP. Accordingly, the SCCP transmits a call setup request message to the base station controller 30a in step 170, and the base station controller 30a transmits a call setup completion message to the SCCP in response to the message.

Accordingly, the SCCP forwards the setting completion message to the PCSI 72a-1 of the ASS-W 72a in step 172, and the PCSI 72a-1 sends the call to the PCC 72a-2. You will be notified of the setting.

Subsequently, the PCC 72a-2 of the ASS-W 72a requests translation of the station number into the NTR 78c of the INS 80 in step 174, and the ASS-W ( The personal communication number is notified to the PCC 72a-2 of 72a. Accordingly, the PCC 72a-2 of the ASS-W 72a requests the position information to the CPSC 72a-3 in step 176. The CPSC 72a-3 then transmits the location information request to the HLR via the ASS-T 80. In response to the request, when the response of the location information request is transmitted from the HLR to the CPSC 72a-3 of the ASS-W 72a in step 178, the CPSC 72a-3 routes to the PCC 72a-2. It delivers the response of the information request.

At this time, if it is determined in step 180 that the personal communication subscriber who is the target of optical illusion is registered as a call-inhibiting subscriber based on the routing information transmitted from the CPSC 78f, in step 182, the PCC of the ASS-W 72a is determined. 72a-2 transmits an incoming call guide access command to the CSL 72a-5, and the CSL 72a-5 then transmits the fixed announcement to the GSC 82b of the ASS-GS 82 in step 184. The GSC 82b transmits the announcement broadcast channel request signal to the SNC 78d of the INS 78 in step 186.

Subsequently, when the SNC 78d transmits a unidirectional switch connection request signal to the SSW 78e at step 188, the SSW 78e is guided to the GSC 82b of the ASS-GS 82 at step 190. The TSW 82a transmits a channel access notification signal, and the GSC 82b receiving the guide broadcast channel access notification signal transmits a T-switch guide broadcast connection request signal to the TSW 82a in step 192. In step 194, a T switch guide broadcast access notification signal is transmitted to the GSC 82b.

Then, the GSC 82b transmits the announcement start request signal to the GSI 82c in step 196. The GSI 82c receiving the request signal is guided to the GSC 82b in step 198. In step 200, the GSC 82b transmits a fixed announcement channel notification signal to the PCC 72a-2 of the ASS-W 72a.

In contrast, as the PCC 72a-2 transmits the announcement broadcast T switch connection request signal to the LSL 72a-4 in step 202, the LSL 72a-4 transmits the TSW 72a-3 in step 204. While the T switch connection request signal is transmitted to the PC, the GSC 82b of the ASS-GS 82 transmits a voice guidance broadcast start notification signal to the PCC 72a-2 of the ASS-W 72a. The call route for the announcement is set, and in step 208, the call forwarding announcement is broadcast to the calling party's personal subscriber, according to the call-in status of the caller.

As described above, according to the method of processing an incoming call in the personal communication switching system according to an embodiment of the present invention, when the corresponding personal communication subscriber is registered as a do not call subscriber when the user wants to send a call to the personal communication subscriber, the incoming call is received.
