It relates to an HDR system having a voice transmission function that can use all of them.

1 is a block diagram schematically illustrating a configuration of a system supporting voice and data communication for a conventional dual mode terminal.

In the communication system having the configuration as shown in FIG. 1, when the user performs data communication using the IS-95 / HDR dual mode terminal 110, the router 180 after connecting to the HDR access point 170. Access to the Internet network 190 through. Accordingly, the user may be connected to the Internet network 190 using the dual mode terminal 110 to perform data communication.

In addition, when a user performs voice communication using the dual mode terminal 110, the user accesses the IS-95 / 1XRTT base station 120, and the base station controller (BTS) 130 and the mobile communication exchange (MSC). It is connected to the public switched telephone network (PSTN) 150 via 140. Accordingly, the user may be connected to the public switched telephone network 150 using the dual mode terminal 110 to perform voice communication with a call counterpart.

Meanwhile, the user may access the IS-95 / 1XRTT base station 120 using the dual mode terminal 110 to transmit / receive wireless data. In this case, the data transmitted from the dual mode terminal 110 is transmitted from the base station controller 130 to the internet network 190 via the data interlocking device 160 and through the router 180.

In addition, the data received by the dual mode terminal 110, in turn, the data provided from the Internet network 190 is transmitted to the data interlocking device 160 through the router 180, the transmitted data Is received by the dual mode terminal 110 via the base station controller 130.

However, such a dual mode terminal has a disadvantage in that hand-off is not provided between the IS-95 and the HDR. In addition, since the dual mode terminal is provided with different frequency bands of the IS-95 and HDR, each terminal should have an RF unit corresponding to each frequency band. Accordingly, since the dual mode terminal must monitor the paging channels of the IS-95 and the HDR, respectively, power consumption is also generated.

The present invention was created in view of the above conditions, and by designing a communication system to support not only data communication but also voice transmission for an HDR dedicated terminal, a user can perform data communication and voice communication through an HDR dedicated terminal. It is an object of the present invention to provide an HDR system with a voice transmission function that can be used.
