Patent number: 11838109Abstract: Time stamp replication within wireless networks is described. In an embodiment, a wireless station receives an input time stamp and uses this input time stamp to generate an output time stamp. The wireless station transmits the output time stamp to wireless stations in one of a number of groups which make up the wireless network. The output time stamp is generated to compensate for delays between receiving the input time stamp and transmitting the output time stamp such that output time stamp which is transmitted at a time T corresponds to the value that the input time stamp would have had if it had been received at time T (and not at a time earlier than T). This may, therefore, reduce or eliminate independent time stamp errors and jitter caused by multiple disparate systems and processes.Type: GrantFiled: December 8, 2021Date of Patent: December 5, 2023Assignee: Imagination Technologies LimitedInventor: Ian Knowles

Patent number: 11792694Abstract: When initiating a Voice-over-IP (VoIP) communication session between an originating device (MO) and a terminating device (MT) on a packet-switched network, network components associated with the MO may encounter a failure when preparing resources for the session, such as a failure to establish a dedicated bearer with the MO. This might typically cause the system to abort the session. Instead, the network components are configured to detect the failure and to initiate a handover to a circuit-switched communication network so that the session may be conducted through the circuit-switched communication network. The failure may be detected by a component of a Long-Term Evolution (LTE) Radio Access Network (RAN) of the network, by a Mobility Management Entity (MME) of the network, or by some other network component. Single Radio Voice Call Continuity (SRVCC) procedures may be used to implement the handover.Type: GrantFiled: May 29, 2020Date of Patent: October 17, 2023Assignee: T-Mobile USA, Inc.Inventors: Kun Lu, Alan Denis MacDonald, Egil Gronstad, Hsin-Fu Henry Chiang, A.

Patent number: 11575656Abstract: Systems and methods herein provide for a proxy infrastructure. In the proxy infrastructure, a network element (e.g., a supernode) is connected with a plurality of exit nodes. At one of a plurality of messenger units of the proxy infrastructure, a proxy protocol request is received directly from a client computing device. The proxy protocol request specifies a request and a target. In response the proxy protocol request, a selection is made between one between one of the plurality of exit nodes. A message with the request is sent from the messenger to the supernode connected with the selected exit node. Finally, the message is sent from the supernode to the selected exit node to forward the request to the target.Type: GrantFiled: February 10, 2022Date of Patent: February 7, 2023Assignee: coretech It, UABInventors: Valdas Pilkauskas, Miroslav Kozlovski, Gytis Ciuta
