Mobile eXchange

Replication of a Cellular Network and Cellular Exchange in Software

Technology

At the core of the PMN solution is the Private Mobile eXchange (PMX), the mobile equivalent of a PBX (Private Branch Exchange) in traditional telephony. The PMX provides the replication of a cellular network and cellular exchange in software, creating a software-based PBX switching solution that enables the creation of the secure and private GSM network, able to be used as an alternative to a carrier’s mobile network.

Private Mobile eXchange creates a switched mobile network

The Private Mobile eXchange creates a switched mobile network that can be either used as a totally self-contained communications solution or integrated with public and corporate telecoms infrastructures. The PMX includes all the features and functionality of a standard GSM network but operates using low powered spectrum GSM.

The PMX is a server (or group of servers) that connects the base transceiver station (BTS) and associated mobile phones to either a corporate PBX and/or the PSTN and GSM networks. The software components together create an integrated switching environment. The outputs from this mobile exchange are SIP and standard IP for data. SIP is able to interface with industry standard gateways. The IP connection will allow delivery of content to the mobiles in the PMN using the GPRS protocol.

The software MSC (Mobile Switching Centre) controls access to the private mobile network and it enables interoperability with PBXs and/or IP-PBXs, thereby extending the reach of the SIP-based telephony applications. A separate component provides standard PBX features such as call routing and number translation. These components provide connectivity to the IP network as well as the BSC (Base Station Controller). The BSC connects locally or remotely to one or more BTS (Base Transceiver Station) in order to create GSM access points. One BSC can manage up to 100 GSM access points, thereby creating an extensive local, private GSM network that can cover a number of different sites or buildings.

Delays in starting work on the project can be avoided with the use of mobile devices, enhancing site communications along with the added advantage that all calls within the network are free. Free calls on-network is an important consideration in cost justifying use of mobile phones and can be substantial against uncontrolled mobile phone costs. In addition, the portable nature of the RDU means that it can be moved from site to site, providing an ongoing communications solution at new sites.
