Patent number: 10708190Abstract: A method of control Maximum Transmission Unit (MTU) reporting and discovery using AT commands is proposed. In communications networks, the MTU of a communication protocol of a layer is the size (in bytes or octets) of the largest protocol data unit that the layer can pass onwards. In an IP network, IP packets may be fragmented if the supported MTU size is smaller than the packet length. In accordance with one novel aspect, the packet data protocol (PDP) context of a packet data network (PDN) connection comprises MTU information. By introducing MTU information to the PDP contexts, TE can use AT commands to query MTU parameters from the network and thereby avoid fragmentation. TE can also use AT command to set MTU parameters and thereby control MTU discovery.Type: GrantFiled: October 25, 2018Date of Patent: July 7, 2020Assignee: HFI Innovation INC.Inventors: Chien-Chun Huang-Fu, Weirong Chu, Yu-Syuan Jheng

Publication number: 20140169289Abstract: The method and apparatus for accelerating connection establishment in a mobile communications system are provided. The method includes transmitting, by a user equipment, an Activate PDP Context Request to a network; determining whether the user equipment can be confirmed that the network received the Activate PDP Context Request by an lower layer; shortening a default timer value and retransmitting the Activate PDP Context Request to the network after the shortened default value if the lower layer does not confirm that the network received the Activate PDP Context Request; and preserving the default timer value if the lower layer confirms that the network received the Activate PDP Context Request.Type: ApplicationFiled: November 26, 2013Publication date: June 19, 2014Applicant: MEDIATEK INC.Inventors: Weirong CHU, Yuan-Chieh LIN, Po-Ying CHUANG, Chi-Hsien CHEN
