The present invention relates to a mobile communication relay technology, and more particularly, to a method and a system for receiving video signal call processing for improving a call failure rate of an incoming video terminal located in an overlapping base station coverage area.

In recent years, mobile communication has expanded its scope from voice services to data services. In particular, interest in high-speed wireless transmission technology for providing various multimedia services is increasing, and CDMA 1x EVDO has been developed to provide various multimedia services. CDMA 1x EVDO implements high-speed wireless transmission using the existing 1.25MHz band frequency, and supports voice service and high-speed packet data service by integrating CDMA 2000 1x and 1x EVDO into one system. Through this, it is possible to provide a variety of content, such as Internet search, MP3, such as web search or e-commerce.

Furthermore, the network configuration of the CDMA 1x EVDO is largely composed of AN (Access Network) and DCN (Data Core Network). The AN has a function of providing a voice communication service to a mobile communication terminal and receiving and transmitting packet data to a DCN. The DCN functions to process packet data of the mobile communication terminal received through the AN. AN is a base station transceiver system (BTS) that performs air interface with a terminal, a base station controller (BSC) that performs call processing and provides a base station and a core network interface, and mobility to wireless subscribers of a network.

Hereinafter, the two embodiments mentioned above will be described in detail.

First, a video telephone system in a base station coverage overlap area for executing multiple accesses to a plurality of base stations 200 and 300 through a single base station controller 400 is generated by a video call request of an originating video terminal (not shown). A base station 200 initially connected to the incoming video terminal 100 of the base station overlapping area responsive to the incoming paging, at least one additional base station 300 constituting the base station overlapping area, and the initial accessing base station 200 Generates cell sector data based on radio wave environment information, receives session information on the incoming image terminal 100 from a data location register 500 which is a DB that manages terminal registration and mobility, and receives the cell sector data and the session.

FIG. 3 is a flowchart schematically illustrating an operation of the system shown in FIG. 2. As shown in FIG. 3, the method for executing the called-side video telephone call processing is performed to the called-side base station controller 400 via the packet data serving node 600 in response to a video call request from an originating video terminal (not shown). When the incoming request is made (S100), the base station controller 400 requests the position lookup of the corresponding incoming video terminal 100 to the data location register 500 (S102). Thereafter, the data location register 500 searches the previously stored DB and notifies the base station controller 400 of the inquiry result about the incoming image terminal 100 (S104). Accordingly, the base station controller 400 transmits the incoming paging to the incoming video terminal 100 located in the base station coverage overlap area (S106), and then multiple calls for a plurality of base stations 200 and 300 constituting the base station coverage overlap area. By executing the connection, the incoming video terminal 100 can seamlessly connect the incoming and outgoing video call call without disconnection (S108). In addition, when a call setup route is established between the incoming video terminal 100 and a predetermined base station through a multi-access process, a gatekeeper (gateway) for connecting the packet data serving node 600 and the originating video terminal (not shown) ( Video call setup is performed via 700 (S114).

In addition, FIG. 4 is a flowchart illustrating an operation of the system illustrated in FIG. 2 in detail. As shown in FIG. 4, the method for executing a more specific called party's video telephone call processing is performed when the called video terminal 100 receives an incoming call according to a video call request from an originating video terminal (not shown) (S200). The base station 200 initially connected to the incoming image terminal 100 retransmits the incoming response to the call processing controller 410 of the base station controller 400 (S202). Subsequently, the base station controller 400 that manages the initial call access base station 200 generates cell sector data through the PN base station list identified based on the received radio wave environment information included in the incoming response, and generates the generated cell sectors. Through the data, it is determined whether it is compatible with the base station. In addition, the call processing controller 410 of the base station controller 400 executes a process of requesting and receiving session information on the incoming image terminal 100 from the data location register 500 (S204 and S206). Subsequently, the call processing controller 410 of the base station controller 400 assigns at least one or more additional base stations 300 for redundant call connection with the incoming video terminal 100 based on the session information and the cell sector data. The access control and resource allocation process is performed (S208). In the step S208, the multi-access setup is performed and the additional base station 300 is selectively set according to the base station signal strength ranking based on the cell sector data, and the number of additional base stations 300 to be selectively set is up to three. It is desirable that it can be set. In addition, the call processing controller 410 requests the multi-access channel resource allocation for each base station by utilizing a multi-PN function (S210, 212), each base station (200, 300) is a multiple access received through the channel controller A channel resource allocation request message is processed and a response message generated thereby is transmitted to the call processing controller 410 (S214 and S216).

Further, the call processing controller 410 of the base station controller 400 that manages the initial call access base station 200 requests the processing module allocation to the data media controller 420 for data packet management (S218). Thereafter, the call processing controller 410 generates a traffic channel assignment message based on the channel resource allocation information of each of the base stations 200 and 300 in response to the processing module assignment (S220), and generates the generated traffic channel assignment message. Is transmitted to the channel controller of each of the base stations 200 and 300 set up in multiple access, and the traffic channel assignment message received by the channel controller of each of the base stations 200 and 300 is retransmitted to the destination video terminal 100 (S222). To S228). Accordingly, when the incoming video terminal 100 receives the traffic channel assignment message through the base station 200 to which the initial call is connected, or receives the traffic channel assignment message through the additional base station 300, the incoming video terminal 100 receives the reverse direction with the received base station. It is turned on by the channel link (S230).

Here, when the incoming video terminal 100 receives the traffic channel assignment message only through the additional base station 300, the related video message is transmitted to the channel controller of the additional base station 300 to be turned on by the reverse channel link ( S232), the channel controller of the additional base station 300 transmits the mobile acquisition information of the incoming image terminal 100 to the call processing controller 410 via the data media controller 420 of the base station controller 400 (S234). .

Thereafter, the incoming video terminal 100 generates a traffic channel completion message in response to the received reverse traffic channel response message, and transmits the generated traffic channel completion message to the channel controller of the additional base station 300 (S244). .

In addition, the channel controller of the additional base station 300 notifies the data media controller 420 of the fact that the message has been received (S246), and the data media controller 420 executes de-packeting for the traffic channel completion message. Transfer to the call processing controller 410 (S248). Thereafter, the call processing controller 410 notifies the data media controller 420 after completing the traffic channel allocation based on the received message (S250).

In step S230, a plurality of reverse links may be formed by all of the called video terminal 100 responding to the traffic channel assignment message provided to the called video terminal 100 via the initial call access base station 200 and the additional base station 300. In that case, another flow is added. This will be described in more detail with reference to FIG. 5. As shown in FIG. 5, steps S300 to S328 correspond to before step S228 of FIG. 4.

Subsequently, the incoming video terminal 100 turns on the corresponding reverse link in response to each traffic channel assignment message received from each base station set up in multiple access, and then passes through the base station to the call processing controller 410 of the base station controller 400. And transfers the mobile acquisition information to each other (S330 to S340). The call processing controller 410 of the base station controller 400, which has received the mobile acquisition information through each path, includes a plurality of base stations 200 and 300 set up in multiple access with the incoming video terminal 100 located in the base station coverage overlap area. The radio signal strength of each base station (200, 300) is determined by rank based on the radio environment information that is reconstructed between the base stations. Set to the root (S342). In addition, subsequent steps S344 to S358 correspond to steps S236 to S250 mentioned in FIG. 4.

Furthermore, the video call processing system for performing at least two base station controllers 400 interworking with each other to execute multiple accesses to a plurality of base stations may respond to an incoming paging generated by a video call request from an originating video terminal (not shown).
