Embodiment 1

[0103] Take the 3G R4 softswitch network as an example, such as Figure 6 As shown, the MSC Server included in the 3G R4 softswitch network and the media gateway MGW interact through the H.248 protocol. The following describes in detail how the media gateway MGW1 under the MSC Server performs user plane disconnection and recovery detection processing.

[0104]MGW1 under the MSC Server continuously monitors the routes from the local end to other MGWs (MGW2). If the office route is not restored within this timer, MGW1 can determine that the office route to MGW2 is disconnected; if the office route to MGW2 is restored within this timer, MGW1 can determine the route to MGW2 The user plane is not disconnected, and the timer is stopped immediately. The above timing mechanism can effectively avoid disconnection misjudgment caused by short-term fluctuations in packet network routing.

[0105] The specific process for MGW1 to know whether the office direction to MGW2 is reachable is...

Embodiment 2

[0128] Taking the IMS network as an example, such as Figure 8 As shown, the MGCF included in the IMS network and the IMS-MGW interact through the H.248 protocol. The media stream processing module in the IMS network can be IMS-MGW, GGSN and SBC. The method of detecting and processing the disconnection and restoration of the user plane by the media gateway IMS-MGW under the MGCF will be described in detail below.

[0129] The IMS-MGW under the MGCF continuously monitors the routing situation from the local end to the peer media stream processing module (GGSN), and if it finds that the office routing to the GGSN is revoked at a certain moment, it starts the disconnection detection method and starts the disconnection detection timer, if the office route is not restored within this timer, the IMS-MGW can determine that the user plane to the GGSN office is disconnected; if the office route to MGW2 is restored within this timer, the IMS - The MGW can determine that there is no sho...

Abstract

The invention discloses a method for detecting an office direction open circuit in a user plane. The method comprises: a local terminal media stream processing module detects office direction from self to an opposite terminal media stream processing module in the same user plane, and judges that the office direction in the user plane is in an open circuit when detecting that the office direction from self to at least one opposite terminal media stream processing module can not be reached. The invention also discloses a method for reporting the office direction open circuit in the user plane, which comprises: detecting whether the office direction in the user plane is in the open circuit; and reporting information of the office direction open circuit to a communication control module when the detection result is that the office direction in the user plane is in the open circuit. Correspondingly, the invention also discloses a method for detecting and reporting office direction recoveryof the user plane, a device thereby, and a device for reporting the office direction open circuit in the user plane. By adopting the proposal, the invention can effectively sense the office directionopen circuit in the user plane and office direction recovery events, and reports the events to the communication control module in time, so that the communication control module can take effective counter measures for the office direction open circuit in the user plane and the office direction recovery events.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a method and device for user-plane disconnection detection, recovery detection and reporting. Background technique [0002] Next Generation Network (NGN, Next Generation Network) is a network that uses a packet communication network as a bearer and separates the control function from the bearer function. exist figure 1 The shown network based on packet communication includes four types of functional modules in a logical sense: a communication control module, a media stream processing module, a module access device, and a packet backbone network module. [0003] The packet backbone network refers to a packet communication network that can provide a bearer channel for communication among communication control modules and media stream processing modules. The interface for transferring communication control information between the media stream processing module and t...
