Description

Method for local loop service of base station {Method for local loop service of base station transceiver}

The present invention relates to mobile communication, and in particular, when a caller and a receiver exist within a service area of a specific base station when a subscriber makes an incoming call during operation of the base station, the service is provided through a base station inner loop for a call processing request. The present invention relates to a local loop service method of a base station for saving resources.

In general, a main system in which a switch is installed in a mobile communication is connected to a base station providing a mobile communication service in a certain area by wire, and a mobile communication terminal capable of transmitting and receiving data wirelessly is connected to the base station wirelessly. To transmit and receive data. Therefore, transmission and reception of signals for call and control between the exchange, the base station, and the mobile communication terminal are essential for providing a high quality mobile communication service.

1 shows a schematic configuration of a base station and an exchange controlling a base station. The base station 10 is a radio station established on the land for communication with a land mobile station or with a relay of a mobile relay station. The wireless interface unit 11 within 10 receives a call processing signal transmitted from the terminal 30 of the mobile subscriber and processes the mobile call generated by performing a wireless access function for connection to the terminal 40 of the receiver. do. The modem 12 in the base station converts a digital signal into an analog signal so as to be transmitted through a communication line, and converts an incoming analog signal into a digital signal. On the other hand, the network setting unit 13 in the base station provides a network path into or out of the base station 10.

The upper base station exchanger 20 interoperates with a plurality of base stations 10 to perform a mobile call processing function, and performs management and control functions for these base stations 10. The vocoder 21 in the upper base station exchanger 20 compresses the voice signal and converts it to digital, and at the receiver side, converts the compressed digital signal back to analog and transmits it. /9.6kbps) to convert the data.

2 illustrates a conventional mobile call processing method of a base station. When an originator terminal 30 transmits an access signal to a base station 10 for a call, the base station 10 receives an upper base station switch (controller) ( 20) transmitting a signal for requesting subscriber authentication (S1) (S2), and receiving resource allocation for the subscriber authentication and call call from the upper base station exchanger 20 and the base station 10 to the called party terminal 40; (S3) (S4) and the vocoder 21 of the upper base station exchanger 20 establishes a path between the caller and the called party, and then performs a call between the calling and called subscribers (S5) and S6.

Meanwhile, when a mobile communication subscriber located in an arbitrary base station 10 requests a call call service to a subscriber in the same base station, the mobile terminal of the subscriber makes a call and receives a signal from the base station 10 so as to receive a signal from the base station 10. The subscriber's authentication process. After the authentication is completed, the resources for performing the call are allocated from the upper base station exchanger 20 and the base station 10 to complete the authentication and resource allocation process for the calling party subscriber.

In addition, after receiving authentication and resource allocation through a similar process to the called party, if a path for a call call is established between the called party and the calling party, a normal call is made between the calling party and the called party.

At this time, the path connection between the two subscribers (Loop) is made in the vocoder 21 in the upper base station exchange 20.

Therefore, conventionally, even if a caller and a called party are located inside a service area of a specific base station 10, the resources for providing the call processing service are actually assigned the vocoder 21 of the upper base station switch 20, so that the base station 10 itself. By connecting a call that can be processed in the upper base station exchanger 20 unnecessarily occupy a double resource, there is a problem inefficient operation of the base station system.

The present invention has been made to solve the conventional problems, by providing a service in the inner loop of the base station itself for the call processing request generated when the sender and the receiver is located in the service area of the specific base station during operation of the base station The purpose of the present invention is to provide a local loop service method of a base station that prevents waste of resources of an upper base station exchanger and converts excess resources into other uses.

A feature of the present invention for achieving the above object is that when the calling subscriber accesses the base station for the call, determining whether the called party is in the same base station by performing authentication and information retrieval of the calling and called party; If the called subscriber is in the same base station, the base station itself may establish a call loop path to allow a call between the calling and called subscribers to be made.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

3 is a schematic configuration diagram of a base station according to the present invention, comprising a calling terminal 30, a base station 10, a wireless interface unit 11, a modem 12, a network setting unit 13, and a called terminal 40. .

When the caller terminal 30 transmits a signal for a call call, the wireless interface unit 11 transmits a signal to the network setting unit 13 via the modem 12, and the network setting unit 13 transmits a signal to the caller terminal ( 30) and the identification and location of the called party terminal 40 is located within the service providing area of the base station 10 to establish a path for the call is made between the caller and the called party.

4 is described as follows in order of a local loop service of a base station according to the present invention.

If the caller and the called party are located in the area serviced by the specific base station, when the caller makes the call and accesses the base station 10, the caller and the called party acquire the authentication and location information of the calling and called party and determine whether the called party is in the same base station. (S11 ~ S13) and, if the called subscriber is in the same base station, and performs the step (S14 ~ S16) to set up a base station loop path so that the call between the calling party and the called subscriber.

On the other hand, when the authentication and location information of the calling and called subscribers are located outside the service area of the base station, the call is established between the calling party and the called party by allocating resources for authentication and calling of the called subscriber from the upper base station exchange. Is done.

As described above, when any subscriber requests a call to another subscriber, the mobile station 10 connects to the base station 10 corresponding to the current location and attempts to perform the authentication. Allocate base station resources to the called party. Next, by determining whether the called subscriber is at the same base station, the location information of the called subscriber is searched to determine whether or not the called subscriber is at a location in the same base station as the calling subscriber. If the called subscriber is in the same base station, the call call loop path is set up in the base station. If the called subscriber is not in the same base station, resource allocation for the call is requested to the higher base station exchange. The call is made to.

As described above, when the sender and the called party are located in the service area of a specific base station, the base station itself may perform call processing in an inner loop, thereby converting resources of the exchange to other uses, thereby increasing efficiency, and Even in the event of a network failure with a higher base station exchanger, continuous service can be provided to the called party in the base station, thereby improving base station operation efficiency and reducing the cost of the exchange.
