Push-to-Talk over Cellular (PTToC) with Radio Interoperability

JPS VIA, powered by the ESChat platform, provides secure voice and data links between mobile devices and JPS gateways. This brings many new features to gateway operators, interoperability system members, and Smart Device users.

System operators and individual users of the gateways’ various communications systems can now communicate via Smartphones and tablets.

Benefits:

• Connection to JPS equipment with RoIP
• Wireless Carrier Independent and Cross Carrier Capable
• Fast Call Setup, Excellent Voice Quality
• Instant Secure PTT Voice and Group Text Communications
• Live and Historical (Bread Crumb) Location Tracking
• ISSI Integration for P25 Networks
• In-Call Preemption and Priority-Based Call Override
• Late Join and Re-Join on Group Calls
• Presence for Groups and Individual Contacts
• Complete User Account Management by Administrators using a Handset or by Web-based GUI
• SIPREC Interface for Professional Third-Party Recording Systems
• Future Improvements include Path to Mission Critical PTT (MCPTT), and Integration With & Visibility Into JPS Gateways

JPS VIA PoC APP is a cloud-hosted service running on commercial 3G/LTE/WiFi networks.

Customers simply purchase the service through JPS, download the application to their Smartphones from the Google Play or Apple App Store, and are charged a monthly service fee per mobile device used.  Wireless Carrier Independent and Cross Carrier Capable, this is an inexpensive option for customers seeking to extend their radio communications capability with lower cost cellular devices.  On-premise systems are available by request.  

ESChat’s addition of the JPS RoIP protocol into their platform, as a result, allows ESChat servers to communicate directly with new and existing JPS interoperability equipment.

This allows the many ESChat-enabled products currently offered to directly connect with JPS gateways and NXU radio interfaces – most importantly for both new deployments or with the large installed base of JPS products.

This drawing demonstrates the vast capabilities of the JPS VIA network.

JPS VIA Use Case Using ACU-M:

Below the JPS VIA PoC APP connects to the JPS VIA Server, which then goes to the JPS RoIP port on the ACU-M.  This allows interoperability between the LMR system on the right, and the JPS VIA APP users on the left.  This saves the cost and resources of everyone having to use LMR radios, the PoC APP users are on the LMR radio network.

Education Use Case with JPS VIA and RSP-Z2:

The Use Case below shows the college administration and college security group on the right using the JPS VIA APP to communicate through the JPS VIA server to the RSP-Z2.  The RSP-Z2 then allows the JPS VIA users to connect to the LMR college security.  Above all, everybody can connect to the police dispatch on the left when necessary.
