The mobile switching station, abbreviated as MSC Server or MSS, is a 2G core network element which controls the network switching subsystem elements. Alternatively or adaptively, MSS can be used in GSM networks as well, if the manufacturer has implemented support for GSM networks in the MSS. Since an immediate upgrade of existing GSM network to ...
Network switching subsystem (NSS) (or GSM core network) is the component of a GSM system that carries out call out and mobility management functions for mobile phones roaming on the network of base stations.
A MSC can serve many BSCs/RNCs, which in turn serves many BTSs. As a result, a MSC can serve a large area, typically hundreds of miles. Highly populated areas require more BTSs and BSCs/RNCs, which will in turn reduce the geographic coverage of a DMSC. The above in a MSC is what's considered as its mobility management.
In mobile cellular telephony networks like GSM and UMTS the SS7 application MAP is used. Voice connections are Circuit Switched (CS) and data connections are Packet Switched (PS) applications. Some of the GSM/UMTS Circuit Switched interfaces in the Mobile Switching Center (MSC) transported over SS7 include the following: B -> VLR (uses MAP/B).
Phases 1 and 2 were defined before 3G networks existed, and as such support adding IN services to a GSM network, although they are equally applicable to 2.5G and 3G networks. Phase 3 was defined for 3GPP Releases 99 and 4, and hence is a GSM and UMTS common specification, while Phase 4 was defined as part of 3GPP Release 5.
ANSI-41 is the standard now approved for use as the network-side companion to the wireless-side AMPS (analog), IS-136 (Digital AMPS), cdmaOne, and CDMA2000 networks. It competes with GSM MAP, but the two will eventually merge [citation needed] to support worldwide roaming. IS-41 facilitates inter-switch operations like handoff and roaming ...
The Radio Network Controller (RNC) is a governing element in the UMTS radio access network and is responsible for controlling the Node Bs that are connected to it. The RNC carries out radio resource management, some of the mobility management functions and is the point where encryption is done before user data is sent to and from the mobile.
The Interworking MSC of the SMSC, on receipt of the MAP mo-ForwardSM message, passes the SMS-PP [2] Application Protocol Data Unit (APDU) containing the text message to the actual Service Centre (SC) of the SMSC for storing, and subsequent "forwarding" (delivery) to the destination address and the SC returns an acknowledgement indicating ...
