Background

An IAB (IntegratedAccess and Backhaul) network consists of a plurality of IAB nodes, each of which may be connected to a plurality of UEs (User Equipment) or other network devices, which may be in different sub-networks. In order to enable communication between these devices, data packets need to be transmitted between different subnets. If all data packets are forwarded from one node to another, this increases the network traffic between the nodes and reduces the network performance. Therefore, the data packet is transmitted in a split flow mode, the data packet can be directly transmitted from the source node to the destination node, the forwarding through the intermediate node is avoided, and the network performance is improved.

In the prior art, under the condition that a data packet of split data of a first centralized unit CU (control unit) in a first IAB network is received, a second CU in a second IAB network determines backhaul adaptation protocol BAP (BehaviorActivity Profile, behavioural profile) configuration information; the second CU configures a second hosting distributed Unit (Data Unit) in the second IAB network to transmit a Data packet to a first IAB node in the first IAB network through a backhaul path in the second IAB network based on the BAP configuration information, wherein the first IAB node is a shunting node.

However, the IAB node topology between the UE and the IAB node is diversified, and the prior art does not set a splitting manner according to the relevant information of the IAB node, but only transmits the data packet to a preset splitting node, which may cause problems of transmission congestion and reduced transmission efficiency.

Example 1

Fig. 1 is a flow chart of a method for shunting transmission of a data packet in an IAB network according to an embodiment of the present application. As shown in fig. 1, the method specifically comprises the following steps:

s101, obtaining the topology structure of the current IAB host node.

Firstly, the usage scenario of the scheme may be that the current IAB host node searches whether a dual-connection IAB node exists, determines an IAB father node of the IAB node if the dual-connection IAB node exists, and finally determines a data sending splitting manner according to relevant information of the IAB father node, and sends a data scenario to the UE according to the splitting manner.

Based on the above usage scenario, it can be appreciated that the execution subject of the present application may be the current IAB host node, which is not limited in this way.

The current IAB-hosting node may be an IAB-hosting node to which the device is currently connected, may be a plurality of different types of devices, and may include, for example:

1. 4G/5G base station: the 4G/5G base station generally has higher processing capacity and network capacity, can play the role of an IAB host node, simultaneously provides access and backhaul functions, and realizes integrated network service.

2. Router/switch: routers and switches typically have good network management and control capabilities, can act as IAB hosting nodes to handle network traffic, and provide access and backhaul functionality.

3. Multimedia gateway: multimedia gateways typically have audio and video processing capabilities, can act as IAB host nodes to handle multimedia traffic and provide access and backhaul functions.

4. Gateway of internet of things: the internet of things gateway generally has better internet of things protocol support and data management capability, can be used as an IAB host node to process internet of things traffic, and provides access and return functions.

Topology may refer to the physical layout of various devices such as computers interconnected by a transmission medium, and refers to the geometry formed during the interconnection process, which may represent the network configuration and interconnections of network servers and workstations. The IAB hosting node topology may be a tree network topology, where individual IAB nodes are hierarchically connected, where the higher the position, the more reliable the node is. I.e., the IAB home node is at the highest position and the IAB intermediate node is at the lower layer position of the IAB home node. In the tree structure, no loop is generated between two nodes in all nodes, and all paths can carry out bidirectional transmission. The topology structure can embody an IAB intermediate node under the IAB host node and the connection relation between the IAB host node and the IAB intermediate node.

The IAB host node may obtain the topology of the current IAB host node by:

1. an IP address or domain name of the IAB host node is determined.

2. And performing route tracking on the IAB host node by using a network tool such as Traceroute and the like to acquire the route path information of the host node.

3. For each router, the SNMP protocol (Simple Network Management Protocol ) is used to obtain other device information of its topology and connections. SNMP can obtain information of network devices through MIB (Management Information Base ).

4. And establishing a network topological graph by using the topological structure and the equipment information, and marking the IAB host node and other connected equipment, thereby obtaining the topological structure of the IAB host node and the IAB intermediate node.

S102, determining whether a double-connection IAB node which is connected with at least two IAB father nodes simultaneously exists according to the current IAB host node topological structure.

In an IAB network, an IAB parent node may refer to a base station connected to a core network, through which other IAB nodes are connected. And a dual-connection IAB node may refer to an IAB node connected to two IAB parent nodes, which may transmit data to the two IAB parent nodes at the same time to improve fault tolerance and reliability of the network.

Based on the current IAB hosting node topology, it may be determined whether there are dual-connected IAB nodes that connect at least two IAB parent nodes simultaneously by:

1. all the IAB nodes are traversed and all the IAB parent nodes and IAB child nodes are identified.

2. For each IAB parent node, it is checked whether at least one of its neighbors is simultaneously connected to another neighbor node of the node.

3. If at least one node exists to meet step 2, the node is a dual-connection IAB node, and at least two IAB father nodes are connected.

4. If no node exists to satisfy step 2, then no dual connectivity IAB node exists in the current IAB hosting node topology.

And S103, if yes, acquiring configuration parameters and real-time loads of at least two IAB father nodes connected with the double-connection IAB node.

Configuration parameters of the IAB parent node may include network topology, network protocol stack, routing policy, security policy, etc., which may affect performance and reliability of the entire IAB network. The real-time load may include the current load status of the IAB parent node in terms of computation, storage, and network.

The configuration parameters and real-time load of at least two IAB parent nodes connected by the dual-connection IAB node are obtained by the following steps:

1. And acquiring a father node list of the double-connection IAB node through an interface in the IAB protocol stack.

2. And for each father node, acquiring configuration parameters and real-time load of the father node through an interface in an IAB protocol stack.

3. And integrating the configuration parameters and the real-time load of each parent node to obtain the configuration parameters and the real-time load of at least two IAB parent nodes connected by the double-connection IAB node.

And S104, generating at least two shunting channels according to the configuration parameters and the real-time load, and determining a shunting mode for transmitting downlink data to the UE through the dual-connection IAB node.

In an IAB network, a split channel may refer to a technique of dividing a data packet into multiple sub-streams according to a certain rule, and then transmitting the sub-streams in parallel through different transmission paths, so as to improve transmission efficiency and reduce delay.

According to configuration parameters and real-time load information of the IAB father nodes, the transmission capacity and the availability of each IAB father node can be determined, so that data packets are distributed to different IAB father nodes according to a certain load balancing algorithm, and at least two shunting channels are generated.

At least two split channels may be generated by:

1. and according to the configuration parameters of the IAB father nodes, including the information of available bandwidth, delay, packet loss rate and the like, the transmission capacity and availability of each IAB father node are evaluated, and the weight of each IAB father node is determined.

2. And according to the real-time load information of the current IAB network, such as data packet transmission quantity, transmission delay and the like, evaluating the real-time load condition of each IAB father node, and determining the real-time load value of each IAB father node.

3. And distributing the data packets to different IAB father nodes according to a load balancing algorithm to generate at least two shunting channels.

In an IAB network, downstream data may be split-transmitted in two ways: time-based and frequency-based splitting.

The time-based distribution is to distribute downlink data packets in a time slice manner, and the data packets of different time slices are transmitted through different distribution channels. The method has the advantages of simplicity and easiness in implementation, but the situation that time slice allocation is unreasonable possibly exists, so that the load of some shunting channels is too high, and the network performance is affected.

Frequency-based splitting is to allocate downlink data packets according to frequency, and data packets on different frequencies are transmitted through different splitting channels. The method has the advantages that the shunt strategy can be adjusted more flexibly, but frequency synchronization is needed among nodes, and the implementation complexity is relatively high.

According to the configuration parameters and the real-time load of at least two IAB father nodes connected by the double-connection IAB node, a shunting mode for transmitting downlink data to the UE through the double-connection IAB node can be determined, if the configuration parameters and the real-time load of the two IAB father nodes are similar and the requirement of the UE can be met in the same time period, the shunting mode based on time can be selected, the time is divided into a plurality of time slots, and only one IAB father node is selected in each time slot to transmit data to the UE; if the configuration parameters and the real-time loads of the two IAB father nodes have obvious differences, or the requirements of the UE cannot be met in the same time period, a frequency-based splitting mode can be selected to divide the frequency band into a plurality of sub-frequency bands, and only one IAB father node is selected in each sub-frequency band to send data to the UE.

S105, transmitting downlink split data to the UE through the at least two split channels based on the split mode; each data packet of the downlink split data includes a data split field, where the data split field is used to inform the UE that the received data is obtained based on at least two split channels when the split character is filled.

The downlink split data may refer to a data transmission mode in which data transmitted to the UE through the IAB network is split into multiple splits and transmitted through different paths, so as to reduce network congestion and improve transmission efficiency.

The data splitting field included in each data packet of the downlink splitting data may be a splitting identifier, which is used to identify the splitting to which the data packet belongs. The split character is a binary value that is added to the packet at the packet header to identify the different splits in the IAB network. The downlink data packet sent in the splitting manner needs to include a data splitting field, which is used for indicating that the data packet is obtained by issuing at least two splitting channels. The data splitting field can be used under the condition of filling in the splitting character, so that the UE is informed that the received data is obtained in a splitting mode, and the UE can combine the data from different splitting channels according to the data splitting field.

The sending of the downlink split data to the UE through at least two split channels based on the split mode may be performed by:

1. and splitting downlink split data to be sent, wherein each data packet comprises a data split field, and the data split field is used for informing the UE that the received data is obtained based on at least two split channels under the condition of filling split characters.

2. And sending the distributed downlink data packets to the generated distributed channels, and dynamically adjusting the bandwidth ratio of each distributed channel according to the configuration parameters and the change of the real-time load to realize balanced distribution of data.

3. After receiving the split data packet, the UE analyzes the data split field, determines through which split channels the data is issued, and performs data recombination to obtain complete downlink data.

Based on the above technical solutions, optionally, after sending downlink split data to the UE through the at least two split channels based on the split manner, the method further includes:

If yes, closing the shunt channel based on the load change data.

In the scheme, the purpose of creating the monitoring task is to periodically detect the load change data of at least two shunt channels so as to adjust the data shunt proportion according to the actual load condition, thereby improving the efficiency and the performance of the system.

The creation of the listening task may be performed as follows:

1. determining a shunt channel to be monitored: and selecting a shunt channel to be monitored according to the specific condition of the system. In general, at least two split channels need to be listened to.

2. Determining a listening time interval: and determining a monitoring time interval according to the real-time load condition of the system and the change condition of the data acquisition request. In general, the time interval should not be too short or too long, typically between a few minutes and a few tenths of a minute.

3. Creating a monitoring task: and writing codes to create monitoring tasks according to the selected programming language and system platform.

Load change data may refer to monitored data about the system load, typically including, but not limited to, CPU usage, memory usage, network bandwidth, and the like. In network systems, load change data is typically used to evaluate the performance and availability of the system and as a basis for adjusting system configuration and resource allocation.

The monitoring of the load change data of at least two split channels according to the monitoring task can be performed by:

1. acquiring real-time load data of at least two shunt channels;

2. comparing the current real-time load data with the last real-time load data, and calculating the variation between the two data;

3. judging whether load change exists currently or not according to the change quantity and a preset threshold value;

4. if the load change exists, calculating a new data distribution ratio according to a preset algorithm, and updating the data distribution ratio between at least two distribution channels;

5. if there is no load change, the next monitoring task trigger is continued to be waited.

Channel shutdown conditions may refer to shutting down one or more channels under certain conditions to optimize network performance, and may include, in particular, the following:

1. the load is higher than a preset threshold: when the load of one channel is higher than a preset threshold, the channel can be considered to be closed, and other channels can be used for data transmission.

2. The data transmission time exceeds the preset time: when a channel has no data transmission for a certain time, it may be considered to shut down the channel to save network resources.

3. The communication quality with a certain node is below a preset threshold: when the communication quality of a channel with a certain node is below a preset threshold, it may be considered to shut down the channel to avoid affecting the network performance.

4. The node offline time exceeds the preset time: when a node goes offline for more than a preset time, it may be considered to close a channel associated with the node to avoid wasting resources.

5. Optimizing a network topology structure: in certain cases, the network topology may be optimized by closing some channels to improve network performance.

According to the load change data, the load condition of each current father node can be calculated, if the load of a certain father node is found to be too high, the data flow carried by the node is too high, and the data distribution imbalance and the congestion problem of data transmission can be caused by continuously maintaining the shunt channel between the node and the node. Thus, a threshold may be set, and when the load of a certain parent node is higher than the threshold, it may be determined whether at least two parent nodes constructing the split channel satisfy the channel closing condition.

The process of closing the bypass channel based on the load change data may include the steps of:

1. And monitoring load change data of at least two shunting channels, and judging the load state of each father node.

2. When the load state of a certain father node is higher than a preset threshold value, the load of the father node is considered to be too high, and the shunt channel can be considered to be closed.

3. If the load state of a certain parent node continues to be above a preset threshold for a certain period of time (e.g., 3 consecutive load change cycles), then the load of that parent node may be deemed to be indeed too high and it may be considered to close the bypass channel with that parent node.

4. After the shunt channel is closed, the data flow can be redistributed according to the current load state, and the balance and the rationality of flow distribution are ensured.

In the scheme, whether the shunt channel is closed or not is determined according to the load change data, the shunt channel is closed based on the load change data, so that network resources can be more reasonably utilized, the condition of network congestion is avoided, the overall performance and efficiency of the network are improved, and meanwhile, the stability and reliability of the network can be ensured.

The technical scheme provided by the embodiment obtains the topology structure of the node connected with the current IAB host; determining whether a dual-connection IAB node which is connected with at least two IAB father nodes simultaneously exists according to the current IAB host node topological structure; if yes, acquiring configuration parameters and real-time loads of at least two IAB father nodes connected with the double-connection IAB node; generating at least two shunting channels according to the configuration parameters and the real-time load, and determining a shunting mode for transmitting downlink data to the UE through the dual-connection IAB node; transmitting downlink split data to the UE through the at least two split channels based on the split mode; each data packet of the downlink split data includes a data split field, where the data split field is used to inform the UE that the received data is obtained based on at least two split channels when the split character is filled. By the method for the split transmission of the data packets in the IAB network, the split transmission can be realized in the IAB network, the utilization rate of network resources is improved, network congestion and delay are reduced, and user experience and network performance can be improved.

Based on the above technical solutions, optionally, after sending the split data to the UE connected to the dual connectivity IAB node by the split method, the method further includes:

In this scheme, the uplink split data may refer to data that is sent by the UE to the IAB network through at least two split channels and is received by a node in the IAB network and then processed. Each upstream split data packet includes a data split field that informs the receiving node on which split channels the data packet was sent.

The current IAB host node may receive uplink split data sent by the UE based on the split character by:

1. and monitoring the double-connection IAB node connected to the current IAB host node, and acquiring configuration parameters and real-time load information of at least two IAB father nodes connected with the node.

2. And generating at least two shunting channels according to the configuration parameters and the real-time load information, wherein the at least two shunting channels are used for receiving uplink shunting data sent by the UE based on the shunting characters.

3. After receiving the uplink split data packet sent by the UE, the splitting character in the data packet is checked to determine which splitting channel the data packet is sent on.

4. And transmitting the data packet to a corresponding shunting channel for processing according to the shunting character of the data packet, namely, decrypting, decompressing, de-duplicating, rearranging and the like the data packet.

In the uplink data offloading process, the UE needs to determine which offloading channel should be selected to transmit data according to the offloading character. Meanwhile, the nodes in the IAB network also need to correctly process and forward the data according to the received splitting characters of the uplink data.

In the scheme, by receiving the uplink split data sent by the UE based on the split character of the split field, the splitting mode of the uplink data of the UE based on at least two split channels can be known. Thus, the IAB network is facilitated to realize data transmission based on distribution, the utilization rate of network resources is improved, the network performance is optimized, and the user experience is improved.

Example two

Fig. 2 is a flow chart of a method for shunting transmission of a data packet in an IAB network according to an embodiment of the present application. As shown in fig. 2, the method specifically comprises the following steps:

s201, obtaining the topology structure of the current IAB host node.

S202, determining whether a dual-connection IAB node which is connected with at least two IAB father nodes simultaneously exists according to the current IAB host node topological structure.

And S203, if yes, acquiring configuration parameters and real-time loads of at least two IAB father nodes connected with the double-connection IAB node.

And S204, if the configuration parameters and/or the real-time load reach preset conditions, determining that the dual-connection IAB node and at least two father nodes construct a split channel.

The preset condition may be a condition that the dual-connection IAB node may construct a split channel with at least two IAB parent nodes. The preset conditions may include:

the preset conditions may include:

1. the link quality between at least two father nodes and the double-connection IAB node reaches certain requirements, such as delay, packet loss rate, bandwidth and the like.

2. The availability of at least two father nodes meets certain requirements, such as network connection stability, equipment failure rate and the like.

3. The real-time load of at least two parent nodes is less than 70%, and a split channel can be established to share the network load.

On the basis of the above embodiment, optionally, if the configuration parameter and/or the real-time load reach a preset condition, determining that the dual-connection IAB node and at least two parent nodes construct a split channel includes:

In this solution, the average value of the Qos requirement data may be a Qos average value, which may refer to an average quality of service level that can be provided by the network system in a period of time. In mobile networks, qoS is often used to measure the performance of the network, such as the speed, delay, and reliability of data transmission.

For configuration parameters and real-time load of each parent node in the IAB network, a QoS average value to be provided by the network can be determined according to a pre-designed QoS rule. And then, judging whether the network can reach the expected QoS average value currently by monitoring and analyzing the configuration parameters and the real-time load of each father node.

Specifically, the following method may be used to identify whether the configuration parameters and real-time load of each parent node can achieve QoS average values:

1. and monitoring the bandwidth utilization rate, the channel interference degree, the transmission delay and other real-time load conditions of each father node so as to know the current network state.

2. And analyzing the data transmission speed and stability among the father nodes according to factors such as the network topology structure, the distance between the father nodes, the signal strength and the like, and judging whether the data transmission speed and stability meet the expected QoS requirement.

3. And evaluating the influence of configuration parameters and real-time loads of each father node on the network performance through methods such as experiments and simulation, and finding out a method and a scheme for optimizing the network so as to improve the QoS average value of the network.

If the configuration parameters and the real-time load of each father node can reach the average value of the service quality requirement data, the split channel between the dual-connection IAB node and at least two father nodes can be determined according to the preset rule. In general, a time-based or frequency-based splitting scheme may be employed, and the data splitting ratio of each splitting channel may be determined according to a preset rule. In this way, the available resources can be utilized to a maximum extent while guaranteeing an average value of the data meeting the quality of service requirements.

If the configuration parameters and/or real-time load of one or more parent nodes cannot reach preset conditions, a shunting channel cannot be constructed with the parent nodes. In this case, only the parent node capable of satisfying the preset condition will construct a split channel with the dual-connection IAB node. In case that the number of the finally constructed split channels of the dual connectivity IAB node reaches at least two, the construction of the split channels is completed. The method can ensure that the constructed split channel can meet the average value of preset service quality requirement data, and improve network performance and user experience.

In the scheme, by identifying the configuration parameters of each father node and/or whether the real-time load can reach the average value of the service quality requirement data, network congestion and delay can be reduced, and the stability and reliability of the network are improved. Meanwhile, by constructing a shunt channel between at least two father nodes and the double-connection IAB node, the data can be shunted and balanced in load, and the network performance is improved. If some father nodes are not able to meet the quality of service requirements, it can avoid setting up a split channel with them, thereby avoiding data loss and network congestion.

On the basis of the above embodiment, optionally, after determining that the dual-connection IAB node and at least two parent nodes construct a split channel, the method further includes:

In this solution, the UE may be a radio device, which refers to a terminal device in a mobile communication system, such as a mobile phone, a tablet computer, etc. In mobile communication networks such as LTE and 5G, a UE is one of the key devices for communication with a base station.

The data acquisition request of the UE may refer to a request from the UE to the network, which requires acquisition of some type of data, such as images, video, audio, text, etc. The acquisition request may be an uplink request, i.e. the UE requests to upload data to the network; or may be a downlink request, i.e. the UE requests to download data from the network to its own device.

The data acquisition request of the UE may be acquired through a network interface protocol or an application program interface. In general, the UE needs to explicitly specify its own required data type in an application and then send a request to the network to acquire the required data. The network may return corresponding data to the UE according to the request type and parameters of the UE.

The target data types for the UE may include a variety of different data formats and content types, such as picture, video, audio, text, binary data, and so forth. The target data type required by the UE can be determined according to the data acquisition request of the UE. For example, if the UE requests to download a picture, its target data type is the picture type; if the UE requests to download a PDF document, the target data type is the PDF file type.

In determining the target data type of the UE, factors such as parameters, data format, coding mode, protocol and the like required by the UE need to be considered to ensure that the network can correctly identify and provide the required data type.

Depending on the target data type, configuration parameters and real-time load, a pre-designed algorithm may be used to determine the data split ratio between at least two split channels. The specific algorithm may vary from case to case, but generally takes into account the following factors:

1. target data type: different types of data may have different priority and QoS requirements. Thus, the algorithm needs to consider the target data type and adjust the split ratio accordingly.

2. Configuration parameters: the configuration parameters may include bandwidth limitations of the dual-connection IAB node and the parent node, processor speed, etc. These parameters may help the algorithm optimize the split ratio to maximize the overall system performance.

3. Real-time load: the real-time load comprises the load level of the current system, the network congestion condition and other information. Based on this information, the algorithm can adjust the split ratio in real time to ensure that the QoS requirements are met and to maximize system throughput.

In the scheme, the data distribution ratio between at least two distribution channels is determined according to the target data type, the configuration parameters and the real-time load, so that the target data type and the service quality requirements of the UE can be better met. According to the target data type, reasonable distribution is carried out on the data, so that the data transmission efficiency can be effectively improved, and the user experience is improved. Meanwhile, according to the configuration parameters and the real-time load, the data distribution proportion is determined, so that the resource distribution can be more accurately carried out, the efficient utilization of network resources is ensured, and the resource waste is avoided.

S205, determining the data distribution ratio between the at least two distribution channels according to the configuration parameters and the preset calculation rule of the real-time load.

The preset calculation rule may be an algorithm used to determine the proportion of data split between at least two split channels. According to the configuration parameters and the preset calculation rules of the real-time load, various factors such as bandwidth of the split channels, network load and QoS (Quality ofService ) requirements and the like need to be considered in determining the data split ratio between at least two split channels. One possible algorithm is to dynamically allocate the data split ratio based on the bandwidth and real-time load of each split channel. For example, a dynamic weight scheduling algorithm may be set to allocate data packets to each split channel according to a certain proportion, so as to ensure that the bandwidth utilization of the whole network is maximized and the QoS requirements of different flows are satisfied. The QoS refers to a technology that a network can provide better service capability for specified network communication by using various basic technologies, is a security mechanism of the network, and is used for solving the problems of network delay, blocking and the like.

Another algorithm is to dynamically adjust the data splitting ratio according to the network delay and packet loss rate of each splitting channel. For example, an adaptive flow adjustment algorithm may be provided to automatically adjust the data splitting ratio according to the network delay and the packet loss rate, so as to optimize the network performance and the user experience.

S206, transmitting downlink split data to the UE through the at least two split channels based on the split mode; each data packet of the downlink split data includes a data split field, where the data split field is used to inform the UE that the received data is obtained based on at least two split channels when the split character is filled.

According to the technical scheme provided by the embodiment, the distribution channel is constructed according to the preset conditions and the preset calculation rules, the data distribution proportion is determined, the data distribution can be realized when the network load is high, the network congestion and delay are reduced, and the stability and the reliability of data transmission are improved. Meanwhile, the balanced distribution of the shunt data can realize the maximum utilization of resources and improve the throughput and performance of the network.
