MSRN - Mobile Station Roaming Number
The Mobile Station Roaming Number is an E.214
defined telephone number used to route telephone calls in a mobile network from a GMSC (Gateway Mobile Switching Centre) to the target MSC (see Network Switching Subsystem
). It can also be defined as a directory number temporarily assigned to a mobile for a mobile terminated call. A MSRN is assigned for every mobile terminated call, not only the calls where the terminating MS lives on a different MSC than the originating MS. Although this seems unnecessary since many vendors' VLR's are integrated with the MSC, the GSM
specification indicates that the MSC and VLR (Visitor Location Register) do not need to reside on the same switch. They are considered two different nodes as they have their own routing addresses. i.e.the MSRN is one of the returned parameters into SRI_Response message. In particular the MSRN is used into an MNP scenario (in this case it can be modified as 'RgN + MSISDN').
Another temporary address that hides the identity of a subscriber. The VLR generates this address on request from the MSC,and the address is also stored in the HLR. MSRN contains the current visitor country code(VCC), the visitor national destination code (VNDC), the identification of the current MSC together with the subscriber number.
If we have all the MSC working as a GMSC like the latest technologies so what would be the states of the MSRN ? we can use it only for test to route the calls to a specific MSC otherwise we don't need it to use it.

E.214
E.214 is a numbering plan used for delivering mobility management related messages in GSM networks. The E.214 number is derived from the IMSI E.212 numbers are composed of two parts. The first, the E.164 part, is made up of a country code followed by the network code. The second part of the...
