# Enabling Mobile Call

Top Previous Next

Descriptions

A mobile-to-mobile call (MMC) is a call between two mobile subscribers. The MMC may be considered an MOC followed by an MTC. The MOC initiation and completion procedures are then handled by the originating MSC/VLR and the MTC initiation and completion procedures are handled by the destination-MSC/VLR. The originating MSC/VLR may also be responsible for the interrogation procedure.

In addition, when the two mobile subscribers are registered in the same MSC/VLR area and the traffic channels are switched entirely within this one MSC/VLR, we speak about a local call. In this case the servicing MSC/VLR performs both the MOC and MTC initiation/completion procedures.

To enable local mobile call, XAPP, MTP3, SCCP and MSC parameters need to be configured on NSS side.
