US Patent 8310990: System, method, and device for routing calls using a distributed mobile architecture

• Title: System, method, and device for routing calls using a distributed mobile architecture
• Inventors: ShaoWei Pan
• Original Assignee: Lemko Corp
• Current Assignee: Lemko Corp. As of March 25, 2025, Piccadilly Patent Funding LLC is listed as a security holder.
• Filing Date: November 9, 2010
• Issue Date: November 13, 2012
• Abstract: Methods and devices are disclosed for routing communications between distributed mobile architecture (DMA) servers using DMA gateways. This involves a first DMA gateway receiving and storing communications information associated with a network accessible by a second DMA gateway. When the first DMA gateway receives a communication for a destination device served by the second DMA gateway, it routes the communication to the destination device by relaying it to the second DMA gateway via a DMA gateway communications network.

Plain-Language Overview of Independent Claims (as described in the detailed description):

1. Computer-Readable Medium for Gateway Routing: This claim describes a non-transitory computer-readable storage medium with instructions. When a processor executes these instructions, it enables a first DMA gateway to receive communication information about a network accessible by a second DMA gateway, store this information, receive a communication for a destination device served by the second DMA gateway, and then route that communication by relaying it to the second DMA gateway through a DMA gateway communications network.
2. Computer-Readable Medium for Server-to-Gateway Routing (Private IP): This claim describes a non-transitory computer-readable storage medium with instructions. When a processor executes these instructions, it causes a first DMA server to receive routing instructions from a first DMA gateway (e.g., an orbiting satellite) while in its service area. The DMA server then sends a call, received from a mobile communication device via its wireless transceiver, to the first DMA gateway over a private Internet Protocol (IP) network, where the call is destined for a device on a legacy communications network accessible by the first DMA gateway.
3. Computer-Readable Medium for Satellite-Based Routing: This claim describes a non-transitory computer-readable storage medium with instructions. When executed, these instructions cause a processor to receive a call at a first interface of an orbiting satellite. This first interface communicates with a legacy network. The call is directed to a mobile communication device accessible by a first DMA server. The instructions then route the call to the first DMA server via a second interface of the orbiting satellite, which communicates with a private IP network. The first DMA server includes a wireless transceiver for the mobile device.
4. First DMA Gateway Device: This claim describes a first DMA gateway device with multiple interfaces: a first for a legacy communications network, a second for a private IP network, and a third for a DMA gateway communications network. The gateway includes logic to receive legacy network information from a second DMA gateway, indicating the legacy network is within the second gateway's range. The first DMA gateway forwards communications received from a DMA server (via its second interface) to the second DMA gateway (via its third interface), where the communication is for a destination device on the legacy communications network.
5. Method for Server-to-Gateway Routing (Satellite Gateway): This claim describes a method where a first distributed mobile architecture (DMA) server receives routing instructions from a first DMA gateway (which is a first orbiting satellite) when the server is in the satellite's service area. A call, received at the first DMA server from a mobile device via a wireless transceiver, is sent to the first DMA gateway over a private Internet Protocol (IP) network according to these instructions. The call is for a destination device accessible via a legacy communications network that is also accessible by the first DMA gateway.
6. DMA Server Device: This claim describes a distributed mobile architecture (DMA) server coupled to a wireless transceiver. The DMA server has a first interface for a private IP network and a second interface for a satellite communications network. It includes logic to receive a call from a mobile communication device via the wireless transceiver and send call information to a DMA gateway (an orbiting satellite). The call is intended for a destination device accessible via a legacy communications network, which is also accessible via the DMA gateway.
7. Orbiting Satellite Device for Routing: This claim describes an orbiting satellite that includes a first interface for communicating with a legacy communications network and a second interface for communicating with a private Internet Protocol (IP) network. The satellite has logic to receive a call via the first interface, where the call is for a mobile communication device accessible to a first DMA server. The satellite then routes this call to the first DMA server via its second interface, with the first DMA server having a wireless transceiver to communicate with the mobile device.

Litigation Information:
According to the legal status timeline, US Patent 8310990 is involved in litigation. A PTAB case, IPR2025-01142, was filed but not instituted (procedural). Additionally, a US case was filed in the Texas Eastern District Court (case number 2:25-cv-00305). First worldwide family litigation was also filed.

No specific CAFC 2026 dockets were found listing US8310990 directly in the general search results, but the existing litigation in district court and PTAB suggests potential for future CAFC activity.
