Description

5. Method of packet service system operation using protocol {Method of packet service system operation using V5.2 protocol}

The present invention relates to subscriber management using the V5.2 protocol, and in particular, the public switched network (Public Switched Data) instead of the local exchange (Local Exchange), which is a public switched telephone network (Access Network) for packet services The present invention relates to a method of operating a packet service system using a V5.2 protocol, which is suitable for managing subscriber status when connected via a network.

In general, the V5.2 protocol is for a Public Switched Telephone Network service in which an access network and a local exchange are connected to E1.

In the above, the access network may use either a wired system or a wireless system. In addition, the local switching network is connected to the public switched telephone network to perform a circuit service.

1 is a diagram showing a system for a public switched telephone network service according to the prior art.

The system of FIG. 1 includes a relay station 11 for managing a terminal and a radio resource, a base station controller 12 for managing a local switching network 20 and a wired resource, and a base station for managing the relay station 11 and a base station controller 12. It consists of a manager 13, a local switching network 20 for exchanging between multiple subscribers in a particular area, and a public switching telephone network 30 for general subscriber service.

The access network 10 includes a relay station 11, a base station controller 12, and a base station manager 13.

The V5.2 protocol consists of public switched telephone networks, basic connection components, link control, protection control, and general control protocols to control call and wired resources between the local switching network and the access network.

In general, outgoing call processing steps of V5.2 are as follows.

First, when the terminal sends an off-hook signal to the access network (10), the access network 10 detects the off-hook signal and sends a dial tone to the terminal.

At this time, the access network transmits an off hook setup signal to the local switching network, and the local switching network sends an off hook acknowledgment signal to the access network.

In addition, the local switching network transmits an allocation request signal specifying an E1 link and a time slot to be used as a bearer to the access network, and the access network receives the signal and sends an allocation completion signal to the local switching network.

From this point, a bearer is established between the access network and the local switching network to transmit a digit and to make a call.

After the call is made, the access network transmits an on-hook signal to the local switching network, and the local switching network 20 transmits a disconnection signal to the access network 10, and the access network transmits a disconnection completion signal to the local switching network.

The local switching network terminates the call by sending a signal for releasing bearer allocation for E1 link and time slot assignment to the access network and sending the de-allocation signal to the local switching network.

For a variety of reasons, the access state and the local switching network may have different subscriber states. In this case, when the access states and the local switching network have different subscriber states, the local switching network controls the access network and the local switching network to have the same state.

That is, when the subscriber of the local switching network is idle and the subscriber of the access network is busy, the local switching network sends a monitoring signal to the access network.

The access network receiving the monitoring signal sends a monitoring acknowledgment signal to the local switching network, the local switching network sends an allocation request signal to the access network, and the access network transmits a deassignment completion signal to the local switching network.

In addition, the local switching network transmits a disconnection signal to the access network, and the access network that receives the signal transmits a disconnection completion signal to the local switching network, thereby making the state of the local switching network and the access network idle.

2 is a flowchart illustrating an incoming call processing step of a packet service according to the related art based on the above contents.

First, the terminal sends an off hook signal to the access network 10 (S30).

The access network 10 detects the off-hook signal and sends a dial tone to the terminal (S31).

In the above configuration, when the access network 10 connects to the public switched data communication network for packet service, the local switching network transmits a monitoring signal to the access network 10 (S32).

The access network 10 receiving the monitoring signal transmits an acknowledgment signal for monitoring to the local switching network 20.

In addition, the local switching network 20 directly sends a release signal for an allocation request specifying an E1 link and a time slot to be used as a bearer (S34).

The access network 10 receiving the deassignment request signal sends a signal to the local switching network 20 that the deassignment is completed.

The local switching network 20 that has received the deassignment completion signal transmits a signal for requesting call disconnection to the access network 10 (S36).

The access network 10 receiving the call disconnection request signal completes the call disconnection and transmits a completion signal to the local switching network 20 (S37).

However, in the above configuration, when the subscriber of the access network 10 performs packet service, the call may be disconnected because there is no method of notifying the subscriber of the local switching network 20 using the V5.2 protocol.

That is, when the user of the access network 10 performs a packet service, the access network 10 is in a busy state, and at this time, the local switching network 20 is idle.

In the public switched telephone network service according to the prior art, when the local switching network calls from the local switching network to the access network, the local switching network is in an idle state, so it operates to adjust the state to each other and sends a call disconnection signal from the local switching network to the access network. There is a problem in that the use fee of the subscriber cannot be settled at the local switching network.

Accordingly, an object of the present invention has been devised in view of the above-mentioned problems of the prior art, and can use a packet service using the V5.2 protocol for a wireless system, and at this time, it is possible to perform a reasonable rate settlement by passing a packet counter. In addition, the present invention provides a method of operating a packet service system using the V5.2 protocol which can prevent call disconnection by an incoming signal in the local switching network by maintaining the same state of the access network and the local switching network.

According to an aspect of the present invention for achieving the above object, the step of delivering a packet service configuration message from the access network to the local switching network, making the state of the local switching network in use, and the access network to the interconnect function device Performing packet service with the local switching network, transmitting packet counter signal to the local switching network together with packet service termination, informing the access network and the local switching network of the packet service termination, and putting the state of the access network and the local switching network into the idle state. And maintaining.

The access network 100 includes a relay station 101, a base station controller 102, and a base station manager 103.

4 is a flowchart illustrating an incoming call processing step of a packet service based on the system of FIG.

First, the terminal transmits an off hook signal to the access network 100 (S100).

The access network 100 detects the off-hook signal and sends a dial tone to the terminal (S101).

At this time, the access network 100 transmits a service setting request signal to the local switching network 200, and since it does not need to allocate a time slot, it sends a service setting request signal indicating that the packet service (S102).

Upon receiving the signal, the local switching network 200 transmits an acknowledgment signal for packet service setting to the access network 100 (S103).

The acknowledgment signal for the packet service setting means that the allocation request signal is not sent, and thus, an incoming call is not made to the local switching network 200.

In other words, the access network 100 is in a packet service subscriber state is in use, and accordingly, the subscriber state of the local switching network 200 is also maintained in use.

In this case, the access network 100 performs a packet service using a public data communication network through the interconnection function device 400.

Performing a packet service When the packet service is terminated, the access network 100 transmits a packet counter to a signal sent to the local switching network 200, thereby enabling the subscriber to calculate a fee according to the use of the packet service (S104).

In addition, the access network 100 transmits a signal for requesting disconnection to the local switching network 200 (S105).

Local exchange network 200 receiving the signal for requesting disconnection notifies each other that the packet service is terminated by sending an acknowledgment signal for disconnection (S106).

Upon termination of service, the subscribers of the access network 100 and the local switching network 200 become idle.

As described above, the packet service operation method of the system using the V5.2 protocol according to the present invention may use the packet service using the V5.2 protocol in a wireless system, and at this time, perform a reasonable charge settlement by passing a packet counter. By maintaining the same status of the access network and the local switching network, it is possible to prevent the call disconnection by the incoming call in the local switching network.
