  • Patent number: 10863436
    Abstract: The present invention is a method for transmitting a data packet by a user terminal in a mobile communication system. The method enters a power saving mode for transmitting the data packet only if a channel state satisfies a transmission threshold value, compares the index indicating the channel state and the transmission threshold value upon occurrence of a data packet to be transmitted, starts transmission of the data packet if the index indicating the channel state is greater than the transmission threshold value, and proceeds with the transmission of the data packet until the time set by the timer that starts at the same time as the transmission of the data packet expires.

  • Publication number: 20200145910
    Abstract: Embodiments herein provide methods and systems for performing paging operation in 5G communication networks. The 5G core network can transmit a NAS message to a UE through a N3GPP access network, if the UE is reachable through the N3GPP access network. The NAS message can be sent by the 5G core network to the N3IWF. The N3IWF can send the NAS message to the UE, through the N3GPP access network. The UE can send a service request over 3GPP access, in response to the NAS message, to the 5G core network, through a 5G RAN. If the UE is not having access to the 5G RAN, then the UE can transmit a notification response message to the 5G core network, indicating the inability to transmit a service request. The transmission of NAS message through the N3IWF can lead to a significant saving of radio resources.

  • Patent number: 10542425
    Abstract: A method and an apparatus reduce overhead for data integrity checks in a wireless communication system. When receiving a message, a first Integrity Check Value (ICV) is compared with a second ICV to detect an integrity error in the message. When the integrity error exists in the message, a frequency of the integrity error is counted. When the frequency of the integrity error is more than a threshold, a key update procedure is performed. Therefore, the overhead of the information for integrity check may be reduced in the wireless communication system.
