Meanwhile, in the internet of things in the industrial field IIoT (Industrial Internet of Things), in V2X (vehicle to X) communication (Device to Device) between devices, in communication of unlicensed spectrum, in user communication quality monitoring, in network planning optimization, in NTN (Non Territerial Network, non-terrestrial network communication), in TN (TERRITERIAL NETWORK, terrestrial network communication), in dual connectivity (Dual connectivity) system, in the above mixture of various communication modes, in radio resource management and codebook selection of multiple antennas, in signaling design, neighbor management, traffic management, in beamforming, the transmission modes of information are all indispensable for 5G system, because they are very helpful to meet the above requirements.

Disclosure of Invention

In various communication scenarios, especially in a wireless network supporting new generation broadcast multicast, a radio bearer is configured for a user according to a specific service, the configured radio bearer may be a unicast bearer or a non-unicast bearer, a non-unicast bearer may be configured in a cell, a unicast bearer may be configured in a cell, and a non-unicast bearer may be configured in a certain time or in other times, so that flexibility of the network and flexibility of resource allocation may be greatly increased, and system resources may be saved, which is an important technical content of 5G broadcast multicast. However, this configuration suffers from a series of problems, namely, when to configure what radio bearer, and how to configure, when the user moves between different cells, if the radio bearer types are different, how to select, how to perform handover, what auxiliary method is needed to perform proper handover and selection, so as to reduce interruption of data; similar problems exist in a cell when the type of radio bearer changes. Non-unicast bearers and unicast bearers are very different, non-unicast bearers, including broadcast or multicast bearers, may be for one cell, one small area, or for a very large area, and many users within an area, so that such bearers are difficult to consider for each user, the serving cell does not even know which users are receiving or interested in receiving, because there is no exact context information about receiving such traffic for these users, so that it is difficult to optimize and involve for each specific user like unicast bearers, and mishandling may be likely to cause loss of interruption of data reception. It is important to let the serving cell keep track of enough information to make the correct decisions, which may include the situation of the user, the reception situation of the user, the situation of interest of the user, the resource usage situation of the user, the service requirements and the service transmission situation of different bearers for different services, etc.

In view of the above problems, the present application provides a solution.

It should be noted that, in the case of no conflict, the embodiments of any node of the present application and the features in the embodiments may be applied to any other node. The embodiments of the application and the features of the embodiments may be combined with each other arbitrarily without conflict.

As one embodiment, the problems to be solved by the present application include: when the type of radio bearer used for transmitting services such as broadcast multicast is required to be determined, or the switch is performed between a non-unicast bearer and a unicast bearer, especially when the switch is performed from the non-unicast bearer to the unicast bearer, the aspects of configuration mode, service capability, resource allocation, bearer management, user management, establishment and release are possibly different due to the great difference between the non-unicast bearer and the unicast bearer, so that in order to correctly implement an algorithm, decision making is required, information about the receiving condition of a user is required to be accurately grasped, and resource configuration and bearer selection are required to be performed according to the information. The application divides the interested service into the first service subset and the second service subset by sending the second signaling, correlates the first service subset and the second service subset with the bearing type, and reports the second service subset by a certain triggering means, so that the base station can establish connection between the service and the bearing type to be used, thereby solving the problems.

As an embodiment, the present application has the following advantages over the conventional scheme:

When a user just enters a new cell, or from a cell transmitting broadcast multicast service over a non-unicast bearer to a cell transmitting broadcast multicast service over a unicast bearer, or when a cell transmitting broadcast multicast service over a non-unicast bearer is converted to unicast bearer to transmit the same service, a key problem is encountered, namely how to assist the serving cell in performing proper configuration, and to deal with the problem of data loss or even interruption during bearer selection or conversion. Because in a cell using a non-unicast bearer, the network may not maintain the context of the user, and the non-unicast bearer does not support feedback from the user side, it is difficult for the serving cell to grasp the receiving situation of the user. When the bearer type of the serving cell is switched, especially when the broadcast multicast service is transmitted by using a unicast mode, if a new independent bearer is directly established between the user and the server according to the traditional method, a long-time service interruption can be caused, and thus, the loss of data is difficult to avoid. It is therefore necessary that the serving cell performs bearer selection or handover at the access level in case the user provides appropriate meaningful assistance information. The application can help the service cell to quickly establish the unicast bearer through the indication of the second signaling, especially through a service set generated by associating the unicast bearer with the service interested by the user, thereby avoiding a lengthy message flow and being simpler, more convenient and quicker than the traditional method.

Traditional unicast service can not directly establish radio bearer through the request of the access layer of the user; the user needs to establish contact with the core network through signaling of the non-access layer, for example, through PDU session, and requests to a functional entity of the core network, for example, an AMF, when the core network is established, if necessary and performs some verification work, the core network establishes an interface to the access network, and the access network can establish a radio bearer for the user, and then can transmit services. For broadcast multicast service, although of broadcast or multicast nature, unicast radio bearers may be used at the time of transmission at the bottom layer, e.g., access layer, e.g., when the number of users in a service area is not large, it is more efficient for the base station to choose to use unicast radio bearers. The traditional flow of establishing unicast bearer is very lengthy for 5G broadcast multicast, and for a broadcast multicast area, a user only needs to request the network once through a non-access layer, and does not need to request the core network again when the bearer changes or is in handover, which can make the function division between the core network and the access network very clear, and is also beneficial for the core network to transmit by using a unified data transmission mode. Meanwhile, the access network directly controls the type of the radio bearer, which is beneficial to reducing time delay and reducing data loss. This is an advantage of the method proposed by the present application.

The method provided by the application can help the service cell to directly initiate the flow of radio bearer establishment by providing the service set related to unicast bearer and the service set related to non-unicast bearer to the service cell, so that the method is compatible with the architecture of the existing protocol to the greatest extent, namely that the establishment and release of the radio bearer are controlled by the base station, the user does not need to directly request or explicitly request, but the base station is assisted to perform configuration in an implicit mode, so that the method is very concise in operation, low in complexity, and capable of reporting the services of different bearers simultaneously with the lowest complexity, thereby reducing signaling overhead.

Example 4

Embodiment 4 shows a schematic diagram of a first communication device and a second communication device according to the application, as shown in fig. 4. Fig. 4 is a block diagram of a first communication device 450 and a second communication device 410 communicating with each other in an access network.

The first communication device 450 includes a controller/processor 459, a memory 460, a data source 467, a transmit processor 468, a receive processor 456, a multi-antenna transmit processor 457, a multi-antenna receive processor 458, a transmitter/receiver 454, and an antenna 452.

The second communication device 410 includes a controller/processor 475, a memory 476, a receive processor 470, a transmit processor 416, a multi-antenna receive processor 472, a multi-antenna transmit processor 471, a transmitter/receiver 418, and an antenna 420.

In the transmission from the second communication device 410 to the first communication device 450, upper layer data packets from the core network are provided to a controller/processor 475 at the second communication device 410. The controller/processor 475 implements the functionality of the L2 layer. In the transmission from the second communication device 410 to the first communication device 450, a controller/processor 475 provides header compression, encryption, packet segmentation and reordering, multiplexing between logical and transport channels, and radio resource allocation to the first communication device 450 based on various priority metrics. The controller/processor 475 is also responsible for retransmission of lost packets and signaling to the first communication device 450. The transmit processor 416 and the multi-antenna transmit processor 471 implement various signal processing functions for the L1 layer (i.e., physical layer). Transmit processor 416 performs coding and interleaving to facilitate Forward Error Correction (FEC) at the second communication device 410, as well as mapping of signal clusters based on various modulation schemes, e.g., binary Phase Shift Keying (BPSK), quadrature Phase Shift Keying (QPSK), M-phase shift keying (M-PSK), M-quadrature amplitude modulation (M-QAM). The multi-antenna transmit processor 471 digitally space-precodes the coded and modulated symbols, including codebook-based precoding and non-codebook-based precoding, and beamforming processing, to generate one or more spatial streams. A transmit processor 416 then maps each spatial stream to a subcarrier, multiplexes with reference signals (e.g., pilots) in the time and/or frequency domain, and then uses an Inverse Fast Fourier Transform (IFFT) to generate a physical channel carrying the time domain multicarrier symbol stream. The multi-antenna transmit processor 471 then performs transmit analog precoding/beamforming operations on the time domain multi-carrier symbol stream. Each transmitter 418 converts the baseband multicarrier symbol stream provided by the multiple antenna transmit processor 471 to a radio frequency stream and then provides it to a different antenna 420.

In a transmission from the second communication device 410 to the first communication device 450, each receiver 454 receives a signal at the first communication device 450 through its respective antenna 452. Each receiver 454 recovers information modulated onto a radio frequency carrier and converts the radio frequency stream into a baseband multicarrier symbol stream that is provided to a receive processor 456. The receive processor 456 and the multi-antenna receive processor 458 implement various signal processing functions for the L1 layer. A multi-antenna receive processor 458 performs receive analog precoding/beamforming operations on the baseband multi-carrier symbol stream from the receiver 454. The receive processor 456 converts the baseband multicarrier symbol stream after receiving the analog precoding/beamforming operation from the time domain to the frequency domain using a Fast Fourier Transform (FFT). In the frequency domain, the physical layer data signal and the reference signal are demultiplexed by the receive processor 456, wherein the reference signal is to be used for channel estimation, and the data signal is subjected to multi-antenna detection in the multi-antenna receive processor 458 to recover any spatial stream destined for the first communication device 450. The symbols on each spatial stream are demodulated and recovered in a receive processor 456 and soft decisions are generated. The receive processor 456 then decodes and deinterleaves the soft decisions to recover the upper layer data and control signals that were transmitted by the second communication device 410 on the physical channel. The upper layer data and control signals are then provided to the controller/processor 459. The controller/processor 459 implements the functions of the L2 layer. The controller/processor 459 may be associated with a memory 460 that stores program codes and data. Memory 460 may be referred to as a computer-readable medium. In the transmission from the second communication device 410 to the second communication device 450, the controller/processor 459 provides demultiplexing between transport and logical channels, packet reassembly, decryption, header decompression, control signal processing to recover upper layer data packets from the core network. The upper layer packets are then provided to all protocol layers above the L2 layer. Various control signals may also be provided to L3 for L3 processing.

In the transmission from the first communication device 450 to the second communication device 410, a data source 467 is used at the first communication device 450 to provide upper layer data packets to a controller/processor 459. Data source 467 represents all protocol layers above the L2 layer. Similar to the transmit functions at the second communication device 410 described in the transmission from the second communication device 410 to the first communication device 450, the controller/processor 459 implements header compression, encryption, packet segmentation and reordering, and multiplexing between logical and transport channels based on radio resource allocations, implementing L2 layer functions for the user and control planes. The controller/processor 459 is also responsible for retransmission of lost packets and signaling to the second communication device 410. The transmit processor 468 performs modulation mapping, channel coding, and digital multi-antenna spatial precoding, including codebook-based precoding and non-codebook-based precoding, and beamforming, with the multi-antenna transmit processor 457 performing digital multi-antenna spatial precoding, after which the transmit processor 468 modulates the resulting spatial stream into a multi-carrier/single-carrier symbol stream, which is analog precoded/beamformed in the multi-antenna transmit processor 457 before being provided to the different antennas 452 via the transmitter 454. Each transmitter 454 first converts the baseband symbol stream provided by the multi-antenna transmit processor 457 into a radio frequency symbol stream and provides it to an antenna 452.

In the transmission from the first communication device 450 to the second communication device 410, the function at the second communication device 410 is similar to the receiving function at the first communication device 450 described in the transmission from the second communication device 410 to the first communication device 450. Each receiver 418 receives radio frequency signals through its corresponding antenna 420, converts the received radio frequency signals to baseband signals, and provides the baseband signals to a multi-antenna receive processor 472 and a receive processor 470. The receive processor 470 and the multi-antenna receive processor 472 collectively implement the functions of the L1 layer. The controller/processor 475 implements L2 layer functions. The controller/processor 475 may be associated with a memory 476 that stores program codes and data. Memory 476 may be referred to as a computer-readable medium. In the transmission from the first communication device 450 to the second communication device 410, a controller/processor 475 provides demultiplexing between transport and logical channels, packet reassembly, decryption, header decompression, control signal processing to recover upper layer data packets from the UE 450. Upper layer packets from the controller/processor 475 may be provided to the core network.
