A method and device for updating parameters in a communication system supporting multi-link are disclosed. An operation method for a first device comprises: transmitting a first frame to a second device through a first link in a multi-link, the first frame including updated parameters used for a communication operation in the first link; transmitting a second frame to the second device through a second link in the multi-link, the second frame including information indicating that the updated parameters are present; and transmitting a third frame including the updated parameters to the second device through one link in the multi-link.

A component of a cellular communication system is configured to prioritize data packets based on packet tags that have been associated with the data packets. The packet tags may comprise an application identifier and a customer identifier, as examples. A Packet Data Convergence Protocol (PDCP) layer of a radio protocol stack receives a data packet and associated packet tags and assigns the data packet to a preferred transmission queue or a non-preferred transmission queue, based on the packet tags associated with the data packet. In order to manage queue overflows, data packets of the non-preferred transmission queue may be discarded when they have been queued for more than a predetermined length of time. Data packets of the preferred transmission queue, however, are retained regardless of how long they have been queued.

Provided in the present disclosure are a service transmission method, a communication device and a storage medium. A terminal establishes at least two mutually associated TCP links with a server to form a TCP link group. Then, during a process of implementing data transmission of a target service with the server by using a first TCP link in the TCP link group, the terminal and the server may also directly hand over the target service to a second TCP link in the TCP link group and continue to perform the target service.

Systems and methods are provided for supporting wide-protocol interface across a multi-die interconnect interface. Data signals of a wide-protocol interface are split into a plurality of data streams. A handshake signal is established between a first circuit and a second circuit, whereby the first circuit and second circuit are dies of a multi-die device. The first circuit transmits the plurality of data streams to the second circuit via a plurality of multi-die interconnect channels. Each data stream of the plurality of data streams are compressed based on the handshake signal in order to provide wide-protocol interface with reduced number of required pins.

A method for transmitting data includes: receiving delay parameter information of a plurality of communication links, in which the delay parameter information is configured to represent an access category (AC) access delay condition of a time sensitive network (TSN) data type under each of the plurality of communication links; and transmitting, based on the delay parameter information, TSN data to be transmitted on a first communication link in the plurality of communication links, in which the first communication link satisfies a TSN data transmission/reception delay requirement.

A method is disclosed for providing network access by a network stack in a communication device comprising a plurality of physical communication interfaces, each comprising a data link layer for the exchange of data frames with remote communication devices and a data link layer interface for exchanging data of data frames between the data link layer and higher layers in the network stack; and wherein the method comprises i) providing an abstraction data link layer comprising a single abstracted data link layer interface such that the plurality of physical communication interfaces appear as a single data link layer interface to the higher layers; and ii) obtaining network packets from the higher layers and distributing the network packets over the plurality of physical communication interfaces according to a neutral packet distribution scheme.

A computer device, having at least two long-range wireless profiles and coupled with a communication bus of a vehicle, receives a notice that a vehicle-centric download for the computer device, or for a vehicle device coupled to the communication bus, is pending from a remote server. The vehicle computer device determines the size and security requirement associated with the pending download, and a current operational state of the vehicle. If the size or security requirement is low, a consumer-centric profile may be used for the download even if the vehicle is currently being used. If the download file size is large or requires very high security, or if a user is currently using the computer device according to the consumer-centric profile, the computer device may schedule the download to occur after receiving a trigger event occurrence message.
