  • Method and device for channel selection
    Patent number: 10764873
    Abstract: The present disclosure discloses a method and device for channel selection. The method comprises: indicating a time-domain resource position and a frequency-domain resource position of an extended physical uplink control channel region based on a common physical downlink control channel; and instructing a group of user terminals to transmit an extended physical uplink control channel in the extended physical uplink control channel region which has been indicated, wherein different user terminals each transmit the extended physical uplink control channel in different extended physical uplink control channel regions which have been indicated. The present disclosure solves a technical problem of a larger downlink signaling cost resulted from the uplink scheduling authorization when a larger number of users transmit data in the extended physical uplink control.

  • Service offload or bypass initiated by a service function forwarder in a service function chaining network
    Patent number: 10749710
    Abstract: In one embodiment, a service function forwarder (SFF) analyzes pre-service state and post-service state of an original packet to determine whether to initiate and perform service offload or service bypass. A service function forwarder (SFF) receives a particular packet having a service function chain (SFC) encapsulation of the original packet, the SFC encapsulation identifying a particular service function path (SFP) designating a particular service function (SF). The SFF extracts pre-service state of the original packet, typically adding it to the particular packet in an In-Situ Operations, Administration, and Maintenance (IOAM) data field (or alternatively storing locally) before sending the particular packet to the particular SF. The SFF receives the particular packet after the SF applies the particular network service.
