Problems solved by technology

However, it is necessary to wait for subsequent signals to determine the business type
If there is a large delay in the H.248 communication between the gateway and the gateway controller, it will lead to the loss and retransmission of the event report, and it will also cause misjudgment of the service type

Embodiment Construction

[0034] Such as figure 1 As shown in , define new events in new H.248 packages or in existing packages (ie figure 2 , 3 preset event in the H.248 protocol), the gateway notifies the gateway controller of the newly added event through the Notify command defined in the H.248 protocol. In the mode where the gateway controller controls the gateway to switch services, this event is used to report the new service type received by the gateway, and the gateway controller can understand the new service type more accurately, avoiding the gateway controller performing business on complex signal combinations Type analysis and judgment, which can avoid the risk caused by misjudgment, and the gateway controller can directly negotiate new capabilities according to the business type reported by the gateway; in the gateway automatic switching business type mode, this event is used to report the business of the gateway By changing and using the RTP resource attributes, the gateway controller ...

Abstract

New added event is defined in new H.248 packet or incurrent packet. Through Notify command defined in H.248 protocol, gateway informs gateway controller the new added event. In mode of gateway carrying out service switching controlled by the gateway controller, the event is in use for reporting gateway that a new type of service is received to let gateway controller know new type service more accurately so as to avoid carrying out analytical judging type of service from complicated signal combination by the gateway controller. Thus, risk caused by misjudge can be avoided. Based on the reportedtype of service, the gateway controller can arrange new capability. Under mode that gateway automatic switches type of service, the new event is in use for reporting change of service of gateway, andutilized attributes of RTP resources. Thus, gateway controller knows service state of gateway in order to satisfy charging requirement.

Description

technical field [0001] The present invention relates to the technical field of Next Generation Network (NGN for short), and more specifically, relates to a method for reporting service switching of a Media Gateway (MG for short). Background technique [0002] In the process of implementing data services such as fax service and modem (Modem) under the NGN architecture, the gateway generally reports service switching to the gateway server (Media Gateway Controller, MGC for short) in the following two ways: [0003] First, the gateway will receive various events (for example, V.21 signal tone and flag (V21flag for short) events) generated in the process of reporting Fax / Modem / Text through the signal detection event defined in the H.248.2 protocol and the user. The incoming Fax / Modem / Text devices send out various signal tones and report them to the gateway controller. [0004] In fact, signal tones themselves do not correspond to service types one-to-one, and some signal tones ...
