ports required in MGW as dividend variables respectively. Voice Mail Service and Home Location Register Each Voice mail service (VMS) and Home location register (HLR) comprises two parts: Base unit; Extension units. The outcome of the algorithm presented in this section is the number of base and extension units for VMS and HLR. The dividend variable for VMS is measured by mailboxes and HLR by the number of subscribers’. The amount of VMS and HLR base units and extension units is calculated according to the algorithm provided in section 7.3.1 Base and extension units concept with mailboxes and the number of subscribers as dividend variables. Service Control (Intelligent Network) Service Control Point (SCP) is the network element, which services pre-paid subscribers. SCP comprises two parts: Base unit (pre - paid related); Extension: Subscribers part; Transactions part. Estimation of the minimum number of SCP base required is a function of requirements to meet the subscribers and traffic demand. In each component’s case calculation algorithms are described below. The amount of SCP base units (BUSCP, units) is calculated according to the following formulas: Where: Npre Pre-paid – subscribers, units; NTr/s Busy hour transactions per second, units; – Maximal operational capacity to satisfy number of subscribers; – Maximal operational capacity to satisfy number of transactions, BH transactions/s; – NTSub GSM, UMTS and LTE subscribers, units; – NBHCA Call attempts in BHT, BHCA; – Average number of IN transactions per one pre-paid subscriber call (on-net and off-net) αt/c- The amount of SCP extension units for subscribers and transactions part is calculated according to the algorithm provided in section 7.3.1 Base and extension units concept with the number of subscribers and BH transactions per second dividend variables.
