Embodiments of the present disclosure include a method, a device, and a system for deploying a network slice. The method, device and system disclosed herein are related to the field of communications technologies, and are designed to solve the problem of low efficiency in manually deploying a network slice. An exemplary solution includes: a first network management unit receiving a network slice management request message that carries service traffic information of a network slice, and, based on the service traffic information of the network slice, deploying the network slice or selecting an available network slice in an existing network.

A service processing method, a service processing apparatus, and a communications system are provided. The service processing method includes: receiving, by an access network device, from a core network device, a bearer setup request message of a voice over Long Term Evolution (VoLTE) service; and rejecting, by the access network device, the bearer setup request message when determining that LTE network signal quality of a terminal of the VoLTE service cannot satisfy the VoLTE service.

Aspects of the subject disclosure may include, for example, determining whether a past throughput of past traffic communicated between a communication device and a communication network meets a first threshold value, resulting in a first determination; responsive to the first determination being that the past throughput meets the first threshold, transmitting an instruction to the communication device to restrict a first subsequent throughput of first subsequent traffic to no greater than a second threshold value; determining whether the first subsequent throughput has been restricted, resulting in a second determination; and responsive to the second determination being that the first subsequent throughput has not been restricted, taking one or more actions to enforce a second subsequent throughput of second subsequent traffic to no greater than a third threshold value, wherein the third threshold value is lower than the second threshold value. Other embodiments are disclosed.

Techniques are disclosed for an adaptive and causal random linear network coding (AC-RLNC) with forward error correction (FEC) for a communication channel with delayed feedback. An example methodology implementing the techniques includes transmitting one or more coded packets in a communication channel, determining a channel behavior of the channel, and adaptively adjusting a transmission of a subsequent coded packet in the first channel based on the determined channel behavior. The communication channel may be a point-to-point communication channel between a sender and a receiver. The channel behavior may be determined based on feedback acknowledgements provided by the receiver. The subsequent coded packet may be a random linear combination of one or more information packets.

A client terminal sends a signal to a wireless access device. The wireless access device receives the signal, determines channel state information corresponding to the client terminal according to identity information of the client terminal in the signal, and calculates data sent by the client terminal according to the channel state information and the signal. The client terminal sends a request signal for acquiring channel state information, wherein the request signal includes identity information of the client terminal. The wireless access device receives the request signal, obtains the channel state information corresponding to the client terminal according to the identity information of the client terminal in the request signal, and sends the obtained channel state information to the client terminal. The client terminal receives the channel state information and the signal and calculates the data sent to the client terminal according to the channel state information and the signal.

This application provides a communication method, includes: sending N data packets in M data packets to an access network device through an air interface; sending M-N data packets in the M data packets to the access network device over a first relay link, where the first relay link includes a first link and a second link, the first link is a link between a terminal device and a first relay terminal, and the second link is a link between the first relay terminal and the access network device; and sending request information to the access network device when a link quality of the first link is less than or equal to a first preset threshold, where the request information is for requesting to update the first relay link to a second relay link.

A system and method for integrating 5g and satellite services. A data stream is received from a first network, and traffic conditions in the first network and a plurality of second networks are analyzed. The data stream is segmented into a first portion and at least one second portion based on the analysis of the traffic conditions, and transmitted over the plurality of second networks. The first portion of the data stream and the second portions of the data stream are received at a destination. The first portion of the data stream and the second portions of the data stream are subsequently reassembled, using reassembly information, to reproduce the data stream received from the first network.

Implementations relate to configuration of wireless communication signals between devices. In some implementations, a method includes determining a transmission scenario associated with transmission of wireless signals of a particular wireless communication protocol from a first device to a second device. The transmission scenario specifies one or more transmission characteristics for the signal transmission. A test message is sent wirelessly from the first device to the second device according to the transmission scenario, and a reply message is received from the second device in response to test message. The reply message includes one or more signal quality indicators that indicate a signal quality of the test message. The transmission scenario is selected as a designated scenario based on the signal quality indicators, and data is wirelessly transmitted from the first device to the second device according to the designated scenario.

Embodiments of the present disclosure provide a method and apparatus for managing a roadside device in vehicle road cooperation, a cloud control platform and a system. The method includes: acquiring, by a cloudside device, a data packet from a roadside device, the data packet including at least one of state information of the roadside device and dynamic traffic information associated with the roadside device; and adjusting a packet transmission policy for a data link associated with the roadside device based on the data packet, the data link comprising at least one of a first downlink from the roadside device to a vehicle, a first uplink from the vehicle to the roadside device, a second uplink from the roadside device to the cloudside device, and a second downlink from the cloudside device to the roadside device, so that personalized management for roadside devices is achieved.

Billions of low-cost autonomous sensors and actuators are expected to join 5G and 6G networks. Most of them will use DRX (discontinuous reception) to save power. However, if an incoming message arrives while the device is in sleep-mode, a complex process is required for the device to obtain its message. Instead, a fast, lean polling method is provided, in which the base station can inform the user devices periodically of their messages on hold, using an encoded matrix of bits, one bit per user device in the network. When a user device wakes up and receives the matrix, it can determine, according to its bit position, whether it has messages waiting. If so, the user device can then transmit a very brief signal in an allocated reply region, at a specific location corresponding to its bit position in the matrix, thereby requesting the message or messages on hold.
