The present disclosure provides a network communication method and a branch apparatus. The method is applied to a branch apparatus which communicates with a central apparatus through a public network. The method includes: receiving a public IP address sent by the central apparatus after determining that a network address translation, NAT, gateway exists between the branch apparatus and the public network, wherein the public IP address is an internet protocol, IP, address of a target interface included in a target NAT gateway; sending a probe request packet to the target interface, the probe request packet including a destination IP address, the destination IP address being different from the public IP address and in the same network segment as the public IP address; obtaining the number of network apparatuses in a forwarding path for forwarding the probe request packet based on a probe result; sending a NAT keepalive packet to the central apparatus based on a preset period, the NAT keepalive packet including a first time to live, TTL, the first TTL being a sum of the number and a first value. Implementing the method provided in the present disclosure may avoid the impact on traffic forwarding of the central apparatus caused by the NAT keepalive packets.

The present disclosure provides data transmission methods and apparatuses and an electronic device. The method includes: receiving, by a user equipment, a resource configuration message from a base station equipment, where the resource configuration message includes configuration information of a transport block over multiple slots (TBoMS) resource; determining, based on the configuration information of the TBoMS resource, the TBoMS resource; where the TBoMS resource carries N transport blocks, N is a positive integer greater than 1, and the TBoMS resource carrying first-type transport blocks included in the N transport blocks overlaps with an uplink sub-band of a sub-band full duplex (SBFD) time-frequency resource; and based on the TBoMS resource, sending, by the user equipment, uplink data to the base station equipment.

The present disclosure provides a method and an apparatus for user equipment (UE) registering, an electronic device and a storage medium. Under 5G core network slice isolation networking, when an AMF network element detects that a UE is unsuccessfully registered on the AMF network element, the AMF network element sends to the UE a registration reject message comprising at least a first cell and a second cell. In this way, when the UE sends registration information again, the UE can select target network slice information based on network slice information configured in the first cell. And a 5G base station, when receiving the registration information from the UE, determines a corresponding target AMF network element based on the target network slice information in the requested NSSAI, such that the UE can be successfully registered to the target AMF network element.

A data processing method, apparatus, forwarding chip and network device are disclosed. The method comprises: acquiring a first packet that needs to be forwarded through the multiple sending and selective receiving path; forwarding, if the network device is a source network device, the first packet to a next hop network device on the multiple sending and selective receiving path respectively through multiple paths comprised in the multiple sending and selective receiving path; forwarding, if the network device is an intermediate network device, the first packet to the next hop network device on the multiple sending and selective receiving path; extracting, if the network device is a destination network device, packet information from the first packet, storing extracted packet information if the extracted packet information is not stored in the network device, and forwarding the first packet to a destination terminal.

The present disclosure provides a packet transmission method. According to the method, data packets to be sent to a wireless terminal are obtained. If a load of each wireless link is greater than a load threshold and the data packets are high-priority data packets, it is determined whether a target wireless link has been selected for the wireless terminal, if not, a target wireless link is selected from all wireless links corresponding to the wireless terminal, and the data packets and a migration message are sent to an AP corresponding to the target wireless link, so that the AP migrates, based on the migration message, low-priority data packets to other wireless links except the target wireless link for sending, and sends the data packets to the wireless terminal through the target wireless link; if yes, the data packets are sent to an AP corresponding to the target wireless link.

The present disclosure provides a data transmission method and apparatus, and an electronic device. The method includes: when there is an overlapping resource between an initial physical downlink control channel (PDCCH) frequency-domain resource of a PDCCH and an initial sub-band full-duplex (SBFD) time-frequency resource of SBFD, determining a target PDCCH frequency-domain resource and a target SBFD time-frequency resource based on the initial PDCCH frequency-domain resource and the initial SBFD time-frequency resource, where the target PDCCH frequency-domain resource does not overlap with the target SBFD time-frequency resource; sending downlink data corresponding to the PDCCH based on the target PDCCH frequency-domain resource, so that a user equipment (UE) receives the downlink data based on the target PDCCH frequency-domain resource determined by the UE. The technical solution of the present disclosure can improve resource utilization rate.

An embodiment provides a cross-domain transmission method and an electronic device. The cross-domain transmission method applied to a network node in a DetNet domain, comprises, if the network node is an egress node in a last DetNet domain that a DetNet-flow data packet passes through, determining an actual transmission latency Δt′ n of the DetNet-flow data packet in the last DetNet domain; based on the Δt′ n and actual transmission latencies of the DetNet-flow data packet when passing through other DetNet domains, determining a to-be-compensated time tc; based on the tc and a tReady, determining a corresponding target scheduling cycle, and placing the DetNet-flow data packet into a periodic scheduling queue corresponding to the target scheduling cycle for scheduling and transmission; wherein the tReady refers to a time point that the present node completes processing on the DetNet-flow data packet based on a set data packet processing manner.

A method of transmitting a deterministic flow, applied to an ingress node of the deterministic flow in a deterministic network domain, comprises, receiving a deterministic flow data packet; determining an index number of an elastic buffer queue (EQ) for buffering the deterministic flow data packet and buffering the deterministic flow data packet in the EQ corresponding to the index number of the EQ; in a current scheduling cycle Cycle x, obtaining a planned EQ resource of a next scheduling cycle Cycle (x+1), wherein the EQ resource at least comprises: an EQ index number and a planned transmission resource amount of the EQ corresponding to the EQ index number; obtaining at least one deterministic flow data packet from the EQ corresponding to the obtained EQ index number, storing the obtained at least one deterministic flow data packet into a physical queue corresponding to the next scheduling cycle Cycle (x+1).

This application provides a packet forwarding method and apparatus. In the embodiment, a headend releases respectively to other nodes on the current path SRv6 TE Policy source path routing and a source path control probe packet, to trigger other nodes on the current path to generate a source path control table. The source path control table contains routing forwarding information that nodes on the path of the existing SRv6 TE Policy conventionally does not care about, in order to use this source path control table to mitigate risks caused by nodes on the path of the existing SRv6 TE Policy not caring about the above routing forwarding information and improve the security of the SRv6 network.

The present application provides methods and apparatuses for implementing clock extension based on an integrated circuit bus IIC. The present application additionally provides a clock extension indication signal line between an IIC master device and a control device in a communication control system. The IIC master device sends a first notification to the control device through the clock extension indication signal line to enable clock extension, so that the control device maintains a pin of a slave device SCL in a low-level state, to suspend data transmission. In the absence of a second notification sent by the IIC master device to the control device through the clock extension indication signal line to cancel clock extension, even if the specified period of the SCL clock cycle ends, the slave device SCL pin connected to the slave device SCL will not be controlled to be in a high impedance state.
