Methods and system for setting up call in CDMA mobile communication system
First Claim
1. A method for setting up a real time data call in a mobile communication system, comprising:
- setting up a control path between an origination base station controller (BSC), a termination BSC and a mobile switching center (MSC) controlling the origination and termination BSCs when a call is set up between an origination side mobile station and a termination side mobile station;
transferring bearer information between the origination BSC and the termination BSC through the set up control path, wherein transferring bearer information comprises;
sending a request from the origination BSC to the MSC along the control path for Connection Management service carrying required information, for setting up a radio link with the origination side mobile station upon reception of a call set up message from the origination side mobile station,sending a request from the MSC to the termination BSC along the control path for a termination number for a call, to set up a radio link between the termination BSC and the termination side mobile station, andtransferring bearer information of the termination BSC to the origination BSC along the control path, and transferring a response to the bearer information from the origination BSC to the termination BSC along the control path, to form the bearer path;
setting up the bearer path between the origination BSC and the termination BSC by using the bearer information transferred along the control path; and
transferring real time video data of at least one of the origination side mobile station and the termination side mobile station between the origination BSC and the termination BSC through the set up bearer path without using traffic resources of the MSC.

Abstract
A method and system for setting up a call in a CDMA mobile communication system, which is suitable for real time transmission of a fast data, such as a video data, between origination and termination mobile stations is disclosed. The method includes setting up a call between an origination side mobile station and a termination side mobile station, transferring bearer information between an origination base station controller (BSC) and a termination BSC through the set up call, to set up a bearer path between the two BSCs, transferring a data of a mobile station between the origination BSC and the termination BSC through the set up bearer path, and clearing the set up call and bearer path after the data is transferred.

14. A mobile communication system, comprising:
-
an origination base station controller (BSC), configured to manage and control at least one origination device; a termination BSC, configured to manage and control at least one termination device; a mobile switching center (MSC), configured to control the origination and termination BSCs; and a router coupled to form a direct bearer channel corresponding to a bearer path between the origination BSC and the termination BSC to allow for real time transfer of video data between the at least one origination device and the at least one termination device, wherein bearer information to set up the bearer path is transferred between the origination BSC and the termination BSC through control paths between the origination BSC, the termination BSC and the MSC, the control paths being different than the bearer path, and wherein real time video data of at least one of the origination device and the termination device is transferred between the origination BSC and the termination BSC through the formed direct bearer channel without using traffic resources of the MSC. - View Dependent Claims (15, 16, 17, 18, 19, 20)

21. A mobile communication system, comprising:
-
origination and termination mobile stations; at least one first Base Transceiver Station (BTS) to form a radio interface with the origination mobile station; an origination BSC configured to manage and control the first BTS; at least one second BTS to form a radio interface with the termination mobile station; a termination BSC configured to manage and control the second BTS; a mobile switching center (MSC) to control calls of the origination BSC and the termination BSC; a home location register connected to the MSC for storage and processing position information for paging subscribers of the mobile stations; and a router to establish a direct link between the origination BSC and the termination BSC to carry a real time video data call, wherein bearer information to establish the direct link is transferred between the origination BSC and the termination BSC through control paths between the origination BSC, the termination BSC and the MSC, the control paths being different than the direct link, and wherein real time video data of at least one of the origination and termination mobile stations is transferred between the origination BSC and the termination BSC through the direct link without setting up a traffic path through the MSC. - View Dependent Claims (22, 23)

24. A method for setting up a real time data call in a mobile communication system, comprising:
-
setting up a call between an origination side mobile station and a termination side mobile station; transferring bearer information along control paths between an origination base station controller (BSC) and a termination BSC through the set up call to set up a bearer path between the origination and termination BSC, portions of the control paths being different than the bearer path; and transferring real time video data of at least one of the origination side mobile station and the termination side mobile station between the origination BSC and the termination BSC through the set up bearer path, wherein transferring the beater information comprises; sending a request from the origination BSC to a mobile switching center (MSC) along one of the control paths for Connection Management service carrying required information, for setting up a radio link with the origination side mobile station upon reception of a call set up message from the origination side mobile station; sending a request from the MSC to the termination BSC along one of the control paths for the termination number for a call, to set up a radio hnk between the termination BSC and the termination side mobile station; and transferring bearer information of the termination BSC to the origination BSC along the control paths, and transferring a response to the bearer information from the origination BSC to the termination BSC, to form the bearer path. - View Dependent Claims (25, 26, 27, 28, 29)
