FIELD: radio engineering, communication.SUBSTANCE: invention relates to mobile communication systems which dynamically pair user communication devices with a personal survivability gateway. The gateway can support the establishment of communication services in case of a network failure between a site where the user communication devices are located and a site which provides user communication services. Preferably, the survivability gateway is configured so that if a network failure occurs, the user does not experience service degradation, or at least significant service degradation. For instance, the user's inbound and outbound messages during such an outage may be routed through the user's personal survivability gateway and a survivability proxy.EFFECT: limiting quality of service degradation.25 cl, 7 dwg |
