KR970031561A - METHOD FOR CANCEL SESSION SET UP IN DSM-CC PROTOCOL - Google Patents

Abstract

The present invention relates to a method for simplifying client-initiated session establishment in the DSM-CC protocol, comprising: a first step of authorizing, from a client to a network, a "client session cancel request" message for a session reset to cancel; Determining whether the message received from the client is a "client session cancel cancellation request" message, and if the client session backup cancel request message is transmitted, after the second and second steps of delivering a "server cancel cancellation request" message from the network to the server; And determining whether the message received from the network from the network to the server is a "server session backup cancel instruction" message, and if the server session backup cancel instruction is a message, determining whether the server can cancel the "session session backup" message. If "cancel session session backup" is not possible by the step, the server session backup could not be canceled. A fourth step of canceling the session session backup of the server and sending a message notifying the cancellation to the network, if a "session cancellation of session session" is possible by the third step. After step 4, if it is determined in step 5 that the server session backup cancel response message has been delivered from the server to the network, and it is determined in step 5 that the "server session backup cancel response" message has been delivered, If the result of the sixth and sixth steps of determining whether or not the session session is canceled is determined that the session session has not been canceled, a message informing the network that the session session canceled has not been canceled is sent to the network. To the client and, on the contrary, if the "session cancellation" is canceled, cancel the session backup on the network, and then click the message informing the cancellation. It comprises a seventh step of sending to the client.

Claims (1)

In a communication method using a message from a client to a server via a network through a network, the client sends a "client session cancel request" message to the client for a session reset to be canceled. A first step of applying to a network; A second step of determining whether the message received from the client is a "client session cancellation request message", and if it is a "client session cancellation request message", forwarding a "server session backup cancellation request" message to the server in the network; ; After the second step, it is determined whether the message received from the network to the server is a "server session backup cancel instruction" message, and if it is a server session backup cancel instruction message, it is determined whether the "session cancel session backup" is possible. With three steps; If the "session cancel session session" is not possible by the third step, a message indicating that the server session session cancel is not transmitted to the network, while if the "session cancel session session" is possible by the third step Canceling a session session with the server and sending a message informing of the cancellation to the network; After the fourth step, a fifth step of determining whether a "server session backup cancel response" message has been delivered from the server to the network; A sixth step of judging whether the "session session backup cancel response" message has been delivered in the fifth step, if the "session session backup" of the server has been canceled; If the determination result of the sixth step is determined that the "session session" has not been canceled, a message informing that the "session session canceled" has not been transmitted to the client in the network, and conversely, if the "session session canceled" And canceling the session backup on the network, and then sending a message informing the cancellation to the client. 7. The method of claim 2, wherein the session backup cancellation method is performed in the DSM-CC protocol. ※ Note: The disclosure is based on the initial application.
