  • Patent number: 11382003
    Abstract: A mobile communication device including a Radio Frequency (RF) device and a controller is provided. The controller is coupled to the RF device and configured to allocate the RF device to selectively communicate with a Packet Switched (PS)-based network using a first subscriber identity or with a service network using a second subscriber identity, and ignore a paging message associated with the first subscriber identity during an ongoing on-demand service associated with the second subscriber identity.
    Type: Grant
    Filed: March 25, 2019
    Date of Patent: July 5, 2022
    Assignee: MEDIATEK INC.

  • Patent number: 11265771
    Abstract: A method of defining ATtention (AT) commands for supporting Service and Session Continuity (SSC) mode 2 and SSC mode 3 of 5G Protocol Data Unit (PDU) session operations is proposed. The AT command can be a notification of an unsolicited result code +CGEV: NW PDN DEACT, +CGEV: NW MODIFY, or +CGEV: ME PDN ACT, or a configuration command +CGDCONT with additional 5G parameters. Additional 5G parameters include an SSC, an old CID, a change reason and a PDU lifetime for the purpose of communicating information regarding the request of PDU session anchor relocation.

  • Patent number: 10021642
    Abstract: A timing control method for a user equipment (UE) in a wireless communications system, including: obtaining a starting time of a data transmission period from information of a data transmission timing received from a base station of a wireless network; obtaining a starting time of a current data processing period; and adjusting a data processing timing so that the adjusted starting time of the current data processing period is ahead of the starting time of the data transmission period by a predetermined time.

  • Patent number: 8505098
    Abstract: A recording, recovering, and replaying method for real traffic is used for processing a plurality of network packets of a plurality of network connections. A recording procedure of the method includes the following steps. A recording parameter (N, M, P) is received. A header and a payload of each network packet of the network connections are completely recorded, and a payload accumulation value of each network connection is accumulated. When one of the payload accumulation values exceeds N, the header of each network packet and first M bytes of the payload are recorded for P consecutive network packets corresponding to the payload accumulation value. When one of the payload accumulation values exceeds N and after the P consecutive network packets of the network connection corresponding to the payload accumulation value are recorded, the header of each network packet is recorded for the network connection corresponding to the payload accumulation value.
