If you are not using Amarisoft LTEIMS and LTEMME running on the same PC, edit the file config/ims.cfg
to set the address of the SIP interface.
To define your UE in the UE database, edit mme/config/ue_db-ims.cfg
.
Parameters such as IMSI, OPC and Key (K) should be given from your SIM cards' provider. Enter those values in the configuration file.
If the IMPI is not provided beforehand, it can be easily derived from the IMSI number. IMPI is composed of the username part and the domain name part. The username part corresponds to the whole IMSI string. The domain name is composed of the MCC and the MNC. For a 15 digit IMSI, take the first 3 digits as the MCC and the two following digits preceded by a 0 as the MNC. The domain name is then in the format mnc<MNC>.mcc<MCC>.3gppnetwork.org
. Finally, the IMPI is in the format username@ims.domain
.
The IMPU is in the format sip:IMSI. Y
ou can assign a phone number as well, in the format tel:number
.
For example :
IMSI =
012340
111111111
MCC = 012
MNC = 34
Domain Name = ims.mnc034.mcc012.3gppnetwork.org
IMPI = 012340111111111@ims.mnc034.mcc012.3gppnetwork.org
IMPU = sip:012340111111111@ims.mnc034.mcc012.3gppnetwork.org
tel:0600000001
