KR940013280A - Control method of communication channel of digital subscriber - Google Patents

Abstract

The present invention relates to a B channel control method for communication in which a digital subscriber can simultaneously set up multiple communication channels on a single physical line to receive a desired service, and receives a channel assignment request from the DCC / DPC blocks 11 and 13. A first step (20 to 22) of investigating whether a subscriber requested from the DCC / DPC blocks (11, 13) is a subscriber to the network, a basic access or a primary access interface, and the first step (20 to 20). 22) After performing the service type check, the second step of searching whether the requested channel is in use by checking whether the requested channel is allocated from the DCC / DPC blocks 11 and 13 by channel management ( 23, 24 and after performing the second steps 23 and 24, notify the DCC / DPC blocks 11 and 13 of the state of the request channel, maintain and manage until the service is terminated, and request channel allocation processing. Waiting for a call Claim is characterized in that performed by the step 3 (25 to 28) to the transition state.

Description

Control method of communication channel of digital subscriber

As this is a public information case, the full text was not included.

1 is a block diagram of a B / D channel connection structure between a digital subscriber matching exchange sub-system and a digital subscriber station of an electronic switching system, which is a distributed control system.

2 is a channel control processing diagram represented by a D channel message between an internal block related to channel control and a user electronic switch system;

3 is a data structure diagram for channel control of a basic / primary access interface,

4 is a flowchart of a channel allocation process according to the present invention.

Claims (1)

The DCC block 11 in charge of the circuit call service of the digital subscriber, the CSL block 12 which is a system common library required for call processing of the DCC block 11, and the CSL block 12 are connected to the digital subscriber. And a DPC block 13 for providing a packet call service of the CSL block 12. The CSL block 12 includes a channel initializer 16, a channel allocation processor 17, a circuit mode channel release processor, and a packet mode channel release processor 18. (19) a method of allocating a channel of a device comprising; Investigate whether the subscriber who is requested channel allocation from the DCC / DPC blocks (11, 13) and the request from the DCC / DPC blocks (11, 13) is a subscriber to the network or a basic access or primary access interface subscriber. After performing the first steps 20 to 22 and the first steps 20 to 22, a service type check is performed, and whether or not the channel requested from the DCC / DPC blocks 11 and 13 by channel management is allocated. The second step (23,24) of checking whether the requested channel is in use or not, and after performing the second step (23,24), the DCC / DPC block (11,13) is notified of the status of the request channel. And maintaining and managing the service until the service is terminated and transitioning to a waiting state for a channel allocation processing request call (25 to 28). ※ Note: The disclosure is based on the initial application.
