Problems solved by technology

When STP-2 fails and the message transmitted by Route2 is discarded, since the application layer cannot know the specific route of the message and the network layer does not necessarily block Route2 according to the protocol, the next time the application layer selects a route, it will select Route2 with the same probability , resulting in a certain degree of call loss

Embodiment Construction

[0024] First, the core of the present invention is described, including (1) implementing temporary deletion and restoration of routes when routes fail, and (2) a method for feeding back routing results from the network layer to the application layer. The following uses MSCe and MGW / SG as examples, but it is not limited to this, and any network element that uses SS7 can be used.

[0025] Second, illustrate the specific implementation method of the present invention:

[0026] like figure 2 , when the application layer MAP sends a request message to the network layer MTPL3 that needs to wait for the response from the peer end, it needs to add the corresponding data area index and application layer identifier of the message to the request message (if the application layer resides in multiple modules, the Add module number information; if there are multiple processes in the application layer, add process information), and then pass it to the next layer, and each layer transparent...

Abstract

The invention relates to a method of a network layer feeding back a routing result to an application layer, the method comprises the following steps: an application layer sends a request message to a network layer and transmits transparently a data section index and an application layer logo of the message. The network layer feeds back the routing result corresponding to the request message according to the data section index and the application layer logo. Based on the prior protocol, the method feeds back the routing result to the application layer by the network layer, then, the application layer determines whether a dynamic routing range is adjusted according to the processing result of the message, therefore, the seventh signaling dynamic routing which can be controlled by an application layer is realized, when an information routing fails or cannot meet the requirement of the application layer are solved, the application layer can adjust directly the seventh signaling routing to be chosen, thereby reducing unnecessary call loss. The invention is a beneficial supplement and an improvement of the prior signaling routing.

Description

technical field [0001] The invention relates to a mobile communication core network, in particular to a method for feeding back a route selection result from a network layer to an application layer. Background technique [0002] At present, there are three kinds of international standards in the third generation of mobile communication, any of which supports the docking with the traditional telecom No. 7 equipment, which includes MSC, HLR and PSTN. For example, in the LMSD stage of CDMA2000, MSCe / MGW, HLRe, and SCPe respectively implement simulation devices such as mobile switching center, user location register, and intelligent control node. In order to solve the adaptation between the circuit domain and the IP domain carrying SS7, the Sigtran protocol is adopted, but the signaling route selection basis of SS7 is still the routing keyword or destination signaling point code provided by the application layer, according to the routing configuration Obtain the coupling or No....
