Sigtran interworking issue between multivendor node

+2 votes
297 views

We are trying to connect open MGW to an AOIP BSC. Both belongs to different vendors. Fluctuation of M3Ua SUA observed at BSC end post Connectivity.

As per MGW vendor BSC is not supposed to send SUA management messages to MGW( DAUD) which is causing MGW to send DUNA to BSC which is causing fluctuations @ BSc end for mgw cluster SPC.

Please be informed, there is no fluctuation @ association level. Kindly suggest and share the actual guidelines.
What should happen as per RFC.

From what I understand, an ASP is a process running on an AS, and a SGP is a process running on a SG. Each ASP SGP link is a SCTP connection.

Also, I understand that SGP is responsible for message-routing, while an ASP is merely an end-point for a SCTP connection.

Given that, are there any extra differences between a ASP and SGP (in addition to the routing-capabilities of a SGP)?

What is the reason behind not having the controlled re-routing in M3UA/SIGTRAN? Is it so that we don't need such procedures in IP world?

Why we use Point codes in SIGTRAN when we have IP address to identify the nodes ?

In SIGTRAN, we have SCTP transport and have Source and destination IP addresses.

In such a case , why we need point codes to identify the destination node ?

i can understand that point codes are needed in SS7 since, its not IP . But why we need point codes in SIGTRAN ?

Assume you have the conditions (one AS, etc.) to allow RC to be optional, does the RFC permit one side (IPSP SE mode for example) to still send an RC and the other to not include an RC? I think the answer is yes, but I can't find an explicit reference permitting it.

This is regarding M3UA SSNM messages.
1. Take an ASP with 2 SCTP link sets with each link set having 2 associations, connecting to two different SGs.

| - - - - -> Link Set 1 (2 Associations) - - - - -> SG 1 - - - - - >|ASP | | HLR-1| - - - - -> Link Set 2 (2 Associations) - - - - -> SG 2 - - - - - >|

If all connections between SG-1 and the HLR-1 break, the ASP would be notified with a DUNA.My question is through which SCTP connection between the ASP and SG-1, the DUNA would be sent in a proper SG implementation?Would it be sent to both connections or to a randomly selected one ?
