It is inserted between communication network and TCP / IP type internet network and performs protocol conversion to connect mobile communication network and internet network.

A content management system (CMS) 170 manages contents transmitted to a mobile communication terminal (MS). This Content Management System (CMS) is a general management of internal and external factors from creation, modification and destruction of knowledge objects called contents, and the authority registration and contents provision of content provider servers (CP). It is in charge of server management and interworking between external and internal applications.

Domain Name System (DNS) 180 is a domain name for the content requested to be transmitted from the mobile communication terminal (MS) under the control of the content management system (CMS), the content is actually located. It translates to an IP address and provides routing information.

Content provider server (CP: Contents Provider) 190 is connected to the content management system (CMS) at least one or more multimedia content (music, melody, image, video content, etc.) at the request of the mobile communication terminal (MS) ) Is transmitted to the mobile communication terminal (MS).

The operation of the voice call service of the conventional mobile communication system having the above configuration will be described.

First, when the power of the mobile communication terminal (MS) (110) is turned on (ON) transmits an Origination signal to the base station (BS) 120 through an access channel (Access Channel). The base station (BS) 120 establishes a traffic channel and transmits a channel assignment signal to a mobile communication terminal (MS) 110 using a paging channel. The mobile communication terminal (MS) 110 confirms the traffic channel setting and transmits a traffic channel preamble to the base station (BS) 120. The base station (BS) 120 acquires a reverse traffic channel (Acquire), and transmits an acknowledgment signal to the mobile communication terminal (MS) 110 to establish a call.

In response to a call request from the transmitting mobile terminal MS1 with the call set up, the MSC 130 requests a call to the receiving mobile terminal MS2 through the base station BS. Send a signal and request a response. When there is a response signal from the receiving mobile terminal MS2, the mobile switching center (MSC) 130 makes a voice call between the transmitting mobile terminal MS1 and the receiving mobile terminal MS2.

When the mobile subscriber connects to a data communication service through his mobile communication terminal (MS) 110, the network interworking device 150 requests an initial connection to the domain name system 180. The domain name system 180 transmits the mobile IP assigned to the mobile communication terminal MS to the content management system 170 and requests access to the main menu of the mobile communication terminal MS. The content management system 170 browses the main menu with the mobile IP assigned to the mobile communication terminal 110. When the mobile subscriber selects a menu through his mobile terminal 110, the content management system 170 requests the URL of the selected menu from the domain name system 180. The domain name system 180 notifies the content management system 170 of the URL of the selected menu. The content management system 170 browses the menu corresponding to the notified URL to the mobile communication terminal 110. The mobile subscriber checks the contents of the menu through his mobile terminal 110 and requests a download from the content management system 170. The content management system 170 requests the URL of the selected content from the domain name system 180 and is notified of the URL of the selected content from the domain name system 180. The content management system 170 pushes the content corresponding to the notified URL to the mobile communication terminal 110 through a traffic channel, and the mobile communication terminal 110 loads the content. do. When the mobile communication terminal 110 downloads the content and moves to a higher menu, the mobile communication terminal 110 returns to the above process and repeats the subsequent process. When the mobile terminal 110 requests termination, the content management system 170 calculates the use of the content. Process the request and request a billing record to the Billing System.

However, in the conventional case, the voice call service and the data communication service of the mobile communication terminal were not simultaneously performed.

That is, when the sender calls the user for a voice call using a data communication service such as Nate or Fimm, the receiving mobile communication terminal MS2 receives a call because it is using a communication channel. A signal indicating that the receiving mobile communication terminal MS2 is busy is transmitted to the transmitting mobile communication terminal MS1.

That is, in the conventional case, if the receiving mobile communication terminal is in data communication when the sender requests a voice call connection, the MSC informs the transmitting mobile terminal that the receiving mobile communication terminal is in a call state. You can notify the recipient that a call came in by switching to a message mailbox.

Data services have a much longer time than voice calls. However, the sender will continue to call several times because it cannot know whether the receiver is in voice or data communication. In addition, since both data communication and voice call are made through the traffic channel, the receiver cannot know who is calling because the voice call is impossible during data communication.

If the receiver is using an additional service such as Call Kipper that informs the receiver via a message if the receiver does not answer when the call arrives, the receiver cannot terminate the current data communication. Information can be known.

Accordingly, the present invention solves the conventional problem that voice communication is impossible when the mobile communication terminal is in data communication, so that the mobile communication terminal can know information on the requested voice communication even when the mobile communication terminal is in data communication.

The downlink pilot channel helps the mobile terminal (MS) to obtain time synchronization of the downlink traffic channel. In addition, a phase reference is provided to enable coherent demodulation, and when hand-off, a reference for comparing signal sizes between base stations (BS) is provided. The pilot channel is an unmodulated direct spread spectrum signal that continues to be transmitted at all base stations (BSs). The downlink paging channel is used to transmit control information to the mobile communication terminal (MS). When the mobile communication terminal receives a call, the mobile communication terminal receives paging information through a predetermined paging channel from the base station BS. The downlink sync (sync) channel is a coded, interleaved, modulated spread spectrum signal that is used to synchronize initial time with the pilot channel. The uplink access channel is used when transmitting control information from the mobile communication terminal (MS) to the base station (BS). When a call occurs in the mobile communication terminal MS, the mobile communication terminal MS transmits call generation information to the base station using an access channel. The access channel is also used in response to paging.

The traffic channel is used to transmit (voice) data of the user including signaling traffic between the base station BS and the mobile communication terminal MS. The downlink traffic channel is also called a forward traffic channel, and in the uplink case, it is also called a reverse traffic channel. When voice information or voice data is replaced with related signaling information, it is called blank-and-burst. In addition, there is a power control channel in the downlink, which allows the mobile communication terminal (MS) to adjust the transmission power of the mobile communication terminal at each set time. In reality, the power control channel does not exist separately, but the power control information is transmitted to the downlink traffic channel at a predetermined frequency period.
