===Mobile switching center server (MSC-Server, MSCS or MSS)===
{{main article|Mobile switching centre server}}

The '''mobile switching center server''' is a soft-switch variant (therefore it may be referred to as mobile soft switch, MSS) of the mobile switching center, which provides circuit-switched calling mobility management, and GSM services to the mobile phones [[roaming]] within the area that it serves. The functionality enables split control between (signaling ) and user plane (bearer in network element called as media gateway/MG), which guarantees better placement of network elements within the network.

MSS and [[Media Gateway|media gateway]] (MGW) makes it possible to cross-connect circuit-switched calls switched by using IP, ATM AAL2 as well as [[Time-division multiplexing|TDM]]. More information is available in 3GPP TS 23.205.

The term [[Circuit switching]] (CS) used here originates from traditional telecommunications systems. However, modern MSS and MGW devices mostly use generic [[Internet]] technologies and form [[Next-generation network|next-generation telecommunication networks]]. MSS software may run on generic computers or [[virtual machine]]s in [[Cloud computing|cloud]] environment.
