Patent number: 11968745Abstract: The present invention discloses methods and systems for providing UICC/eUICC related response information to information requests at a cellular router. The method includes receiving an information request from a wireless communication module, and determining whether a response to the information request is cached. When the response information is not cached, forwarding the information request to a massive SIM apparatus (MSA). MSA will then respond to the information request. A response based on the MSA's response will then be sent to the wireless communication module for the information request. When the response information is cached, retrieve the response information and send it to the wireless communication module.Type: GrantFiled: May 28, 2021Date of Patent: April 23, 2024Assignee: Pismo Labs Technology LimitedInventors: Uzair Ahmed Chughtai, Man Kit Kwan, Yu Yeung, Fawad Ahmed, Tomas {hacek over (S)}eirys, Azim Ul Islam, Chun Kit Chan, Kaho Ho Ho

Patent number: 11950321Abstract: The present invention discloses methods and systems for communicating at a cellular router between a first wireless communication module and a first subscriber identity module (SIM). The cellular router receives a first request from a first wireless communication module and encapsulates the first request in a first modified request. The cellular router then sends the first modified request to a first SIM card in a first communication apparatus and waits for a first modified reply. While waiting for the first modified reply the cellular router sends at least one halt message to the first wireless communication module after a first time threshold. After receiving the first modified reply, the cellular router decapsulates the first modified reply to retrieve a first reply and sends the first reply to the first wireless communication module where the first modified reply is a reply to the first modified request.Type: GrantFiled: August 31, 2022Date of Patent: April 2, 2024Assignee: Pismo Labs Technology LimitedInventors: Uzair Ahmed Chughtai, Man Kit Kwan, Yu Yeung

Patent number: 11943060Abstract: Methods and systems for managing an error correction mode at a first communications router. The first communication router transmits data packets to a second communications router and stores the first data packet in a local storage medium. When a delay inquiry message is received from the second communications router, the first communications router activates the error correction mode. When the error correction mode is activated, the first data packet is retransmitted to the second communications router and an error correction packet corresponding to the first data packet is also transmitted. When a back-to-normal message is received from the second communications router, the first communications router deactivates the error correction mode. The back-to-normal message indicates that the first communications router no longer needs to be in error correction mode.Type: GrantFiled: June 12, 2023Date of Patent: March 26, 2024Assignee: Pismo Labs Technology LimitedInventors: Patrick Ho Wai Sung, Kam Chiu Ng, Ho Ming Chan
