US7606885B2 — Patent Overview
Title: Method for, and a topology aware resource manager in an IP-telephony system
Patent number: US7606885B2 (application US10/363,628; also published as US20030187986A1)
Inventors: Jim Sundqvist, Anders Larsson, Joakim Norrgard, Olov Schelen
Assignee of record (as listed): NetSocket Inc (original assignee); reassigned to OPERAX AB (2003) and later back to NETSOCKET, INC. (2008–2009). Per the source, current assignee is listed as NetSocket Inc.
Key dates: Priority date 2000-09-05; filing date 2001-09-03; publication of US20030187986A1 2003-10-02; grant/publication of US7606885B2 2009-10-20. Legal status: Expired – Lifetime (anticipated expiration 2021-09-03).
Purpose (from the excerpt): The invention concerns a method and arrangement in a communications network, specifically IP telephony resource management and admission control within an IP telephony system. It addresses the problem that, in H.323 networks, the gatekeeper is the manager of a zone and performs call control functions including address translation and bandwidth management; the excerpt notes the bandwidth-management implementation is vendor specific, with a common approach being a threshold on simultaneous calls in the gatekeeper's zone, and that Quality of Service (QoS) issues were later added to H.323. The described context covers H.323 components—terminals (T), gateways (G), gatekeepers (Gk), multipoint control units (MCU)—and packet-switched IP networks routed via OSPF, IS-IS, or RIP.
Plain-language scope: The patent relates to managing IP-telephony resources and controlling call admission in a way that is aware of network topology.
What the excerpt does not establish: The supplied text does not include the claims, the full detailed description, or the abstract, so the precise metes and bounds of the claimed invention cannot be determined from it. It contains no verbatim claim language, no specification of how the topology-aware resource manager is implemented, and no limits on claim scope. Accordingly, no statement here should be read as describing the actual claimed subject matter beyond the general field and context indicated.

Assignment history
Inventors, original assignee, and the chain of ownership recorded with the USPTO — including the correspondent attorney who recorded each assignment, since shell-LLC chains often share one repeat-player attorney even when the entity names look unrelated. Surfaces NPE / patent-troll patterns: shell-entity transfers, known asserters in the chain, repeat correspondent fingerprints, pre-litigation assignments, and bankruptcy fire-sales.
