Etherstack's LTE25 solution bridges LTE networks and existing APCO P25 narrowband networks with an integrated, push-to-talk solution. Traditional radio handsets communicate seamlessly with 4G Android devices, allowing for true interoperability in multi-vendor P25 / LTE networks. LTE25 consists of a number of elements hosted (preferably) within the LTE Evolved Packet Core.
A high availability all-IP SIP & RTP based softswitch designed specifically for mission critical radio networks. The softswitch supports a rich supplementary service feature set based on public safety LMR network call types including group calls, fast call setup times, emergency calls and encrypted voice services. The solution supports geographical redundancy (disaster recovery node) and multiple LTE25 softswitches can be deployed within the EPC to provide regionalization of voice traffic services (reducing backhaul considerations) or greater segregation of traffic services (e.g. police vs. industry).
A high availability all-IP data service node (SGSN/GGSN) that manages SNDCP data connections for secure applications on the LTE25 Android Client handsets, such as encrypted location.
A high availability network element that manages cryptographic key distribution within the LTE25 and APCO P25 network solution. The KMF manages Over-The-Air-Rekeying (OTAR) sessions between LTE25 Client handsets and the key manager in the network. Etherstack's KMF can be used to rekey either LTE25 client handsets or traditional P25 client handsets from the same manager simultaneously. One or more KMFs (private or shared) can be deployed in the EPC.
Etherstack’s state of the art Local Operations Console (LOC) provides team management functions within the client’s enterprise network. Distinct from a larger Network Operations Centre (NOC) based console from manufacturers such as Zetron and Intergraph, the LOC provides a desktop based solution blending AVL / GPS fleet management and dispatch calling functions. Utilizing Google Earth mapping, the LOC communicates with the LSC to provide mapped location details of team members within the network. The LOC can see both LTE users and P25 users simultaneously and establish calls to individuals or groups of users at the click of a mouse.
