A communication system is described herein which has at least two compact 'network-in-a-box' systems which are configured such that when a mobile station roams from a first radio coverage area supported by a first compact system into a second radio coverage area supported by a second compact system then packets originating from an IP host will be routed to the mobile station via a GGSN and a SGSN in the second compact system instead of through a GGSN in the first compact system and then through the SGSN in the second compact system as had been done in the past.

Dynamic GGSN relocation in a GPRS network

A portable telecommunications system (PTS) allows mobility and rapid deployment with minimal on-site configuration. PTS systems exchange multicast packets including location and identification information. A protocol manager sets up these communications channels, manages exchanges between PTS systems, and passes the data to or from internal system nodes. The PTS system detects when another PTS system is operating in close physical proximity and automatically perform actions, such as adjustment of transmission power level, to maintain service to the user base.

Auto-control of radiation power in a portable telecommunication system

A communications network and method for providing a voice message to a user of a mobile station (MS) in a network having a plurality of independent mobile systems, each independent mobile system including a Mobile Switching Center (MSC), Short Message Service Center (SMS-C) and Voice Message System (VMS), wherein each VMS is identified by a unique identifier code. A received voice message is stored in a VMS, and an SMS notification message is sent to the MS. Because each VMS is identified by a unique identifier code, the MS can retrieve a voice message by dialing the code contained in an SMS notification message, regardless of which independent mobile system is serving the MS at the time the voice message retrieval is requested.

Distributed fault-tolerant voice message system for independent mobile telephony networks

A portable telecommunications system (PTS), and discovery and update protocol provides an ad-hoc system in which PTS systems can detect one another over a wide area network (WAN). The system may be compact in a way that allows mobility and rapid deployment with minimal on-site configuration. PTS systems exchange multicast packets and peer-to-peer data exchanges. A protocol manager sets up these communications channels, manages exchanges between PTS systems, and passes the data to or from internal system nodes. The protocol manager also performs key oversight functions such as signaling to other systems that a PTS is joining or leaving the community, keeping track of which other PTS systems are in the community and active, and determining when data needs to be updated and exchanged.
