KR960020571A - Mobile subscriber call control method in mobile communication switch - Google Patents

Abstract

The present invention relates to a method for controlling a subscriber's incoming signal in a mobile communication switch.

The present invention is a base station controller (BSC) which is a base station controller; Mobile Service Switching Center (MSC); And a Home Location Register (HLR) that manages the location registration of subscribers, and when a paging is requested from an origination and a paging response is received from the destination MSA 1b, the destination subscriber information is transmitted. A first step of receiving from a) and becoming an alerting state; A second step of receiving the alerting and placing a call when the incoming call is answered in the waiting state for waiting for an incoming call; It is performed by a third step of performing a release process at the end of the subscriber call, it is configured as described above to provide an efficient call control method.

Description

Mobile subscriber call control method in mobile communication switch

As this is a public information case, the full text was not included.

1 is a structural diagram of a mobile communication system to which the present invention is applied;

2 is an incoming call state transition diagram according to the present invention.

Claims (4)

A base station controller (BSC) 10 which is a base station controller; ASS (Access Switching Subsystem) (13) to perform distributed call processing, INS (Interconnection Network Subsystem) (14) to perform centralized call processing, and Central Control Subsystem (CCS) to centralize operation and maintenance A mobile service switching center (MSC) 11 including (15); And a home location register (HLR) 12 that manages the location registration of subscribers; If paging is required from the origination and a page response is received from the destination MSA (1b), the first step (21) is received from the originating MOC 1c and placed in an alerting standby state. 23); A second step (24, 25) of receiving the alerting and performing an incoming call when the incoming call is answered in the waiting state for the incoming call after performing the first step; And performing a teardown process at the end of the subscriber call after performing the second step. 2. The method of claim 1, wherein the first step receives an paging response message from a mobile station signaling access (MSA) 1b after receiving a paging response from an idle state, and receives an incoming subscriber information. When the paging request for paging to the MPC 1f is requested from the MCC 1c, the mobile paging controller 1f loads the base station information to the MSA 1b to request paging, and the MSA 1b Requesting paging to the base station controller (BSC) 10 and receiving a paging response from the BSC 10 sends a page response message to the mobile call controller (MCC) 1c and receives a paging response. The MCC 1c transmits an incoming subscriber page notification message to the MPC 10f informing the MPC 1f that the incoming paging is successful, and is in a waiting state for receiving subscriber information from the originating party. In step 30 to 33 and when the called party information is received from the originating MOC 1c in the reception waiting state, an incoming call setup request message is transmitted to the MSA 1b, and an alerting wait state is entered (34). And a method for controlling an incoming call of a mobile communication switch, characterized in that performed by -36). 2. The method of claim 1, wherein the second step connects a ringback tone to an originating subscriber when receiving an alerting notification from the MSA 1b in the alert waiting state, and the incoming call is ringed to the originating MOC 1c. Transmitting the alerting notification message that the user is busy, waiting for the next beep (40 to 43) in the incoming response waiting state, and when the incoming call is answered, the MSA 1b transmits the incoming response notification message, and the MOC 1c It is performed by the steps 44 to 48 of cutting the ringback tone sent to the originating party, connecting the calling channel, connecting the calling channel, transmitting the incoming call response notification message to the calling MOC 1c, and becoming in a busy state. An incoming call control method of a mobile communication switch, characterized in that. The call cutting notification message according to claim 1, wherein the third step further comprises: when the incoming call first disconnects the call in the busy state, when the incoming call disconnection notification message is received from the incoming MSA 1b, the incoming call disconnection notification message is sent to the calling MOC 1c. When the call is disconnected from the calling party (50-53) and the calling party first disconnects the call, the call cutting notification message is sent from the calling MOC 1c, and the call cutting is made. When the notification message is received, the outgoing disconnection notification message is sent to the called party MSA 1b, and the incoming call disconnection completion wait message waits for the incoming call to be disconnected. When the incoming call disconnection completion message is received from the incoming MSA 1b, the call is received. A method for controlling incoming calls in a mobile communication switch, characterized in that it is carried out by steps (54 to 59) of cutting the furnace and placing it in an idle state. ※ Note: The disclosure is based on the initial application.
