Problems solved by technology

[0011] The problem in providing SVD services in the CDMA mobile communication system of the related art is that mobile terminals and base stations should at least meet IS 2000 Release A that allows SVD services
[0012] Furthermore, another problem that exists in the prior art system that provides SVD service is: when requesting voice service and packet data service at the same time, it needs to spend a long time until all business negotiations of voice service and packet data service are completed

Embodiment Construction

[0044] According to one embodiment of the present invention, by adding a new speech RLP frame type to the RLP frame used for transmitting standard packet data in the packet data service option in the CDMA mobile communication system, by only implementing one for transmitting together and The service options for receiving voice and packet data enable mobile terminals and base stations that cannot support SVD services to provide SVD services. Furthermore, mobile terminals and base stations supporting SVD services can provide SVD services by implementing only one service option for transmitting and receiving voice and packet data together.

[0045] The call processing procedure between the mobile terminal and the base station for providing the SVD service can use the same method as the general call processing procedure of packet data. The call processing procedure can perform SVD call processing by defining a new SVD service option or by exchanging additional signaling informatio...

Abstract

A method and apparatus for simultaneous voice and data (SVD) service in mobile communication system are disclosed. SVD service can be provided by designating a new voice RLP frame type and adding the new voice RLP frame type in the RLP frame transmittal standard for packet data in CDMA mobile communication system. Further, by designating the new SVD service option or additional signaling message exchange, the signaling procedures or multiplexing and de-multiplexing procedures used for SVD service can be simplified. Thus, mobile terminals and base stations, which could not provide SVD service, can be enabled to provide SVD service by performing SVD call processing between mobile terminals and base stations with only one service option.

Description

technical field [0001] The present invention relates to a method for simultaneous voice and data transmission (SVD) in a mobile communication system. Background technique [0002] In general, mobile communication systems based on Code Division Multiple Access (CDMA) are classified into synchronous systems in which base stations use the Global Positioning System (GPS) and mobile terminals operate on an isochronous time base; and asynchronous systems in which base stations do not use GPS. The services in this CDMA mobile communication system can be divided into voice communication services, short message services using signaling, and wireless data services using packet data. [0003] Synchronous CDMA mobile communication systems can be classified into "CDMA 1" and "CDMA2000". First, "CDMA 1" is a comprehensive system that includes IS95, the second-generation wireless packet protocol. Secondly, "CDMA2000" is a comprehensive system based on IS-2000's third-generation wireless...
