Hello,

I am trying to test our SRVCC implementation.

In the "PS to CS Request" message from MME to EMSC, there is no specific format in which target cell id is sent.

Do you have any inputs how i can encode and send and decode the same. ?

29.280 sec 6.9 says refer to MAP spec 29.002, But MAP spec doesnot specify anything.

Is there some format like "PLMN id", LAC etc passed in ..If so why this is not specified in specs !

thanks a lot

When target eNodeB is not able to allocate resource for all the bearers which comes as part of Handover Request message, it sends handover request ack with partial success since "E-RABs Failed to Setup List" is present in HOReqAck message.
What MME or source eNodeB does in that case ? Does any action taken by MME for the E-RABs which failed to setup at target eNodeB or some other actions taken ?

In case of S1 Handover, we have two path for data forwarding "direct" or "Indirect". How we can decide to choose direct data forwarding? Is it based on X2 Connection ( UP or Down ) OR based on any other configuration parameter?
