    Publication number: 20210075744
    Abstract: A network device includes a network interface for establishing a communication session with another network device, a memory to store instructions, and a processor to execute the instructions. The processor may, for each time period during the communication session, adjust a size of a receive buffer of a socket. When the processor adjusts the size, the processor, if a utilization number of the receive buffer is greater than a high threshold: may determine a first new size for the receive buffer, and set a size of the receive buffer to the first new size. If the utilization number is less than a low threshold, the processor may determine a second new size for the receive buffer; and set the size of the receive buffer to the second new size.

  • SYSTEM AND METHOD FOR INDICATING COVERAGE TYPES FOR USER DEVICES IN DUAL CONNECTIVITY WIRELESS NETWORKS
    Publication number: 20210014917
    Abstract: Systems and methods described herein improve a customer experience for non-standalone cellular networks by displaying a secondary cell group (SCG) network icon after data activity ends while a user device likely remains in SCG coverage. When connected to the SCG, the user device detects inactivity on the connection and initiates a first timer, based on the detecting, while continuing to present an SCG-related icon. If the first timer expires while the user device is in an idle state, the user device initiates a second timer, while continuing to present the SCG-related icon. If the user device detects an active connection before expiration of the second timer, the user device initiates a third timer while continuing to present the SCG-related icon. If the user device fails to detect a connection to the SCG before expiration of the third timer, a master cell group (MCG)-related icon is displayed.
