Publication number: 20190373444Abstract: 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.Type: ApplicationFiled: July 13, 2018Publication date: December 5, 2019Applicant: Pismo Labs Technology LimitedInventors: Uzair Ahmed CHUGHTAI, Man Kit KWAN, Yu YEUNG

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.Type: ApplicationFiled: July 13, 2018Publication date: December 5, 2019Applicant: Pismo Labs Technology LimitedInventors: Uzair Ahmed CHUGHTAI, Man Kit KWAN, Yu YEUNG

Patent number: 10298416Abstract: The present invention discloses a method and system for processing a first layer two packet converting a first layer two packet to a first unicast layer two packet at a wireless access point. The wireless access point receives first one or more layer three packets and extracts a first layer two packet from the first one or more layer three packets. If the first layer 2 packet is a multicast packet and it satisfies the predefined rule, the first layer two packet is converted to a layer two unicast packet with a first destination address and send to a Local Area Network (LAN) network interface. If the first layer two packet does not satisfy the predefined rule, it is broadcast to one or more LAN network interface. When the first layer two packet is not a multicast packet, it is sent to its corresponding destination address through one or more LAN network.Type: GrantFiled: November 21, 2016Date of Patent: May 21, 2019Assignee: PISMO LABS TECHNOLOGY LIMITEDInventors: Kam Chiu Ng, Yu Yeung, Ka Kei Liu

Patent number: 10050867Abstract: The present invention discloses methods and systems for transmitting broadcast data at a communication gateway. When the communication gateway receives a broadcast packet from a host or node, the communication gateway determines whether the broadcast packet satisfies at least one condition. If the broadcast packet satisfies the at least one condition, it is determined whether or not to modify a time to live (TTL) value. The TTL value of the broadcast packet is modified if it is determined to modify the TTL value. The broadcast packet is then forwarded to the destination address of the broadcast packet based on the TTL value. The destination address is reachable through an interconnected network.Type: GrantFiled: October 29, 2014Date of Patent: August 14, 2018Assignee: PISMO LABS TECHNOLOGY LIMITEDInventors: Ho Ming Chan, Kam Chiu Ng, Yu Yeung, Kwok Yui Mok

Publication number: 20170134361Abstract: The present invention discloses methods and systems for printing messages on a print medium. The system comprises a server, a print server, and a gateway. The print server receives a list of server messages from a remote server and also receives a user input from a user. Based on the user input, the print server determines whether a printing message should be printed on the print medium. The printing message is determined from the list of server messages. The gateway also receives a first password list from the remote server and an input password from a user. If the input password matches one of the passwords in a verification password list, the gateway allows the user to access a network.Type: ApplicationFiled: May 28, 2015Publication date: May 11, 2017Applicant: PISMO LABS TECHNOLOGY LIMITEDInventors: Yu Yeung, Kang Yin Su
