Problems solved by technology

[0003] From the above description, it can be seen that AG interacts with SS through the uplink service interface to implement ISDN services. Therefore, once the communication between the uplink service interface and the softswitch is interrupted, the message exchange between IUA and SS will not be possible, thus causing the ISDN service to be interrupted. ; Only after the uplink service interface returns to normal, the ISDN service can be resumed

Embodiment 1

[0018] This embodiment provides an ISDN service processing method. figure 1 is a flowchart of an ISDN service processing method according to an embodiment of the present invention, such as figure 1 As shown, the method includes:

[0019] Step S102, the access gateway decodes the message of the ISDN service;

[0020] Step S104, process the ISDN service according to the decoding result.

[0021] In this embodiment, the access gateway decodes the message of the ISDN service. In this way, when the communication between the uplink service interface and the softswitch is interrupted, the access gateway can also decode the message of the ISDN service, thereby performing corresponding service processing. This solves the problem in the related art that when the communication between the uplink service interface and the softswitch is interrupted, the ISDN service will also be interrupted, thereby achieving the effect that the ISDN service will not be interrupted when the uplink servic...

Embodiment 2

[0028] In view of the problems existing in the related technologies, this embodiment provides a method and a gateway for ISDN self-switching in the access network. The method and the gateway can be used to ensure ISDN user services when a communication failure occurs on the uplink service interface, so as to realize docking The protection of the ISDN user's uplink service interface in the ingress gateway, so as to solve the problem of all ISDN user services being interrupted due to the communication interruption of the uplink service interface in the current access network.

[0029] figure 2 is a schematic diagram of ISDN self-switching according to an embodiment of the present invention, such as figure 2 As shown, the main contents of this embodiment include:

[0030] 1. Increase the link check mechanism of the uplink service interface. When the link of the uplink service interface is normal, AG and SS communicate normally, and implement ISDN service through IUA; when the...

Embodiment 3

[0035] This embodiment describes the embodiment of the present invention in detail through a specific example. image 3 It is a flow chart of AG working in ISDN self-switching mode according to an embodiment of the present invention, wherein the process includes step S302 to step S330.

[0036] Step S302, the calling ISDN user ( image 3 Middle ISDN user 1) picks up the hook, sends the Q.931 message of SETUP (1) (set up a call) to AG (the following messages are all Q.931 messages), and the AG prepares to receive the number.

[0037] In step S304, the calling ISDN user sends an INFORMATION (2) (information) message to the AG, and the AG receives the number.

[0038]Step S306, the AG number collection ends, by the encoding submodule of the Q931 message processing module (hereinafter referred to as the Q931 encoding submodule), encapsulate a CALL PRO (3) (that is, CALL PROCEEDING, indicating that the message is received and is being processed) message, and Send this message to ...

Abstract

The invention discloses an integrated services digital network (ISDN) service processing method and an ISDN service processing device. The method comprises the following steps of: decoding a message of an ISDN service by using an access gateway; and processing the ISDN service according to a decoding result. By the method and the device, the problem that the ISDN service is interrupted when communication between an uplink service interface and soft switching is interrupted in the prior art is solved, and an effect that the ISDN service is not interrupted when the communication between the uplink service interface and the soft switching is interrupted is achieved.

Description

technical field [0001] The present invention relates to the communication field, in particular, to an integrated services digital network (Integrated Services Digital Network, ISDN for short) service processing method and device. Background technique [0002] In the Next Generation Network (NGN for short), the Access Gateway (AG for short) connects ISDN users to the softswitch through the ISDN User Adaptation Layer Protocol (IUA for short). (Soft Switching, referred to as SS). The communication between the uplink service interface of the AG and the softswitch is crucial, and the IUA implements the user's ISDN service by exchanging messages with the softswitch. During the interaction process, the ISDN user sends a Q.931 message to the AG, and the AG encapsulates it into an Internet Protocol (IP) message through IUA and sends it to the softswitch, and the softswitch decodes the received message from the access gateway , and are treated differently. [0003] From the above d...
