Description

Method and apparatus for wireless communication network terminal to extend discontinuous reception period configuration

Technical Field

The present invention relates to the field of wireless communication networks, and in particular, to a method and apparatus for expanding discontinuous reception period configuration of a wireless communication network terminal.

Background

The extended discontinuous reception is a technology applied to the network terminal to reduce the power consumption of the network terminal, and the parameters are configured by the base station, and the main configuration parameters comprise discontinuous reception period duration and paging time window duration. In a 5G communication network, the current configuration method of the extended discontinuous reception parameter configures a fixed parameter on a 5G base station based on an empirical value and notifies the fixed parameter to a network terminal. Along with the expansion of 5G application in vertical industry, 5G network terminals and service types also show diversified trends, and the application of the network terminals in different industries puts more demands on the functions of the network side. The third generation partnership project international standard conference discusses a technology for enhancing an extended discontinuous reception mechanism of a 5G lightweight network terminal, and the 5G lightweight network terminal in a radio resource control-inactivity state can support an extended discontinuous reception period length of up to 10485.76 seconds, which means that the network terminal can monitor a physical downlink control channel and paging messages in a paging time window in a longer period of time in the radio resource control-inactivity state, wherein the period of time is determined by an extended discontinuous reception period configuration parameter. The existing method for configuring the parameters of the extended discontinuous reception period duration cannot meet the requirements of saving energy consumption and reducing communication time delay, if the configured extended discontinuous reception period is too long, a network terminal cannot receive paging messages from a core network and an access network in a longer dormancy period in the extended discontinuous reception period, so that the network is caused to be in 'out-of-line' with the network terminal for a long time, larger communication time delay is caused, and backlog of downlink service data on a 5G base station is caused; if the extended discontinuous reception period duration is configured too short, excessive power consumption of the network terminal is caused. The prior proposal has the limitations, and needs to research and select more reasonable extended discontinuous reception period duration and flexible configuration method. In view of the above, this need can be addressed by introducing artificial intelligence techniques into discontinuous reception parameter configuration methods. The existing discontinuous reception configuration method in the standard specification does not adopt artificial intelligence technology, for example, the 3GPP standard only standardizes a simple configuration method through discontinuous reception fixed parameters, and the flexible expansion discontinuous reception configuration requirement in the service diversity scene cannot be solved, so that certain limitation exists.

Detailed Description

For the purpose of making the objects, technical solutions and advantages of the present application more apparent, the technical solutions of the present application will be clearly and completely described below with reference to the accompanying drawings, and it is apparent that the described embodiments are some embodiments of the present application, not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the application without making any inventive effort, are intended to be within the scope of the application. In order to facilitate a clearer understanding of various embodiments of the present application, some relevant background knowledge will first be explained.

Based on the existing 5G network architecture (e.g., fig. 1) and the existing protocol stack architecture (e.g., fig. 2 and 3), a discontinuous reception mechanism was introduced in the third generation partnership project (3 GPP) R15 version. As shown in fig. 1, a Uu interface is between the UE and the 5G base station (abbreviated as gNB), and the Uu interface adopts wireless connection. The UE represents a network terminal; uu interface between network terminal and 5G base station.

Uu interface communication protocol stack as shown in fig. 2 and 3, the radio resource control layer is a key part of the protocol stack, and its function is to control all radio resources, so that communication between the network terminal and the 5G base station is possible. The radio resource control layer defines three states: the radio resource control-inactive state, radio resource control-connected state and radio resource control-idle state, and the transition relationship between the three states is shown in fig. 4. The UE adopts a discontinuous receiving mechanism, namely, the network terminal periodically monitors a physical downlink control channel in a wireless resource control-idle state and a wireless resource control-non-active state to receive paging messages sent by the 5G base station, and the rest time enters a dormant state without monitoring the paging messages, so that the power consumption can be greatly reduced. The basic principle is shown in fig. 5. The increase in 5G network vertical applications requires that the network be compatible with a wider variety of network terminals, such as 5G lightweight network terminals, and the configuration parameter types and attributes of the network are also extended. The discontinuous reception period is extended based on the discontinuous reception basic principle, namely an extended discontinuous reception (abbreviated as extended discontinuous reception) mechanism is introduced, and the discontinuous reception period in the radio resource control-idle state is extended from 10.24 seconds to 10485.76 seconds, so that the sleep time of the network terminal is longer, and the power consumption is saved. The enhancement of the extended discontinuous reception mechanism of 5G lightweight network terminals is discussed in the 3gpp r18 release, and a radio resource control-inactive 5G lightweight network terminal may also support an extended discontinuous reception period of no more than 10485.76 seconds, which means that such network terminals may monitor the physical downlink control channel and paging messages for a longer period of time. As shown in fig. 6, an in-network terminal listens to a downlink channel and paging messages only during a Paging Time Window (PTW) during one extended discontinuous reception period (eDRX period), and the rest of the time is in a sleep state. PTW: paging time window.

When the UE completes the startup registration procedure, the state reserved by the UE in the core network element is a registration management-registered state, and the state relationship between the reserved state of the UE in the core network and the state relationship between the UE in the 5G base station are shown in fig. 7. After the network terminal is successfully started and registered, a core network Authentication Management Function (AMF) can keep context information of the network terminal; the network terminal context represents: after the network terminal establishes contact with the network, the network needs to store necessary information of the network terminal, such as network terminal capability, authentication information, accessed 5G base station identifier, and the like.

As long as the 5G base station triggers the release of the context information of the network terminal to the AMF through the NG interface, the core network considers that the UE is in a core network-defined connection management-connection state, and even if the network terminal is in a radio resource control-inactive state at this time, the core network still transmits downlink service data to the 5G base station, which causes that the 5G base station needs to reserve a large amount of UE service data. The extended discontinuous reception period is longer in duration, which means that the network terminal does not monitor the paging message for a longer time, resulting in missing part of the paging message, service delay and a large amount of downlink data being stored in the 5G base station. Therefore, the reasonable and flexible configuration of expanding the discontinuous receiving period duration and the paging time window duration and the data storage method under the configuration are problems to be solved. AMF: a core network authentication management function network element; and NG, an interface between the 5G base station and the network element of the core network authentication management function.

The invention introduces an LSTM prediction model in the field of artificial intelligence to solve the problems. The artificial intelligence model is applied to the training and reasoning process. The training process is to adjust and determine parameters of the model by sample data, including ideal values of ownership weights and deviations, and the training process is to generate the model; the reasoning process is to input the data model to be applied to start working after the neural network model is trained. The LSTM prediction model is a long-term and short-term memory neural network model.

As shown in fig. 8, the present invention provides a method for expanding discontinuous reception period configuration of a wireless communication network terminal, which is applied to a network terminal, such as a 5G lightweight network terminal, a mobile phone, etc. The method comprises the following steps: s1, a 5G base station configures initialization parameters of a network terminal, and the network terminal sends or receives uplink service flow data and downlink service flow data through an access network under the configuration.

S2, the 5G base station records downlink service flow data and buffer report data in a first time period, and predicts the flow in a second time period according to the downlink service flow data.

S3, the 5G base station calculates and updates new extended discontinuous receiving period duration and paging time window duration based on a downlink service flow data prediction result of the second time period, buffer report data and information of storage space allocation for the network terminal by the 5G base station, and the 5G base station allocates the storage space for the network terminal by a dynamic storage allocation module, wherein the dynamic storage allocation module comprises a storage calculation module and a dynamic storage space module.

S4, when the network terminal in the radio resource control-non-activated state switches the RNA area, the target 5G base station sends updated new extended discontinuous reception period duration and paging time window duration for the network terminal.

Fig. 9 is a block diagram employed in the present invention. As shown in fig. 9, a computing function module is deployed inside the gNB-CU and is responsible for the computing function in the present invention, including: the device comprises a flow prediction module, a storage calculation module and an extended discontinuous reception period calculation module; the traffic prediction module is used for predicting downlink traffic data of the network terminal UE; the storage calculation module is a sub-module of the dynamic storage allocation module in the gNB-CU and is used for calculating the storage space of the network terminal UE in the gNB-DU, the calculation result of the storage calculation module is notified to the gNB-DU through the F1 interface message, and the gNB-DU allocates the storage space for the network terminal UE according to the received calculation result; the storage space module is used for storing downlink business flow data to be received by the UE and data to be transmitted in the uplink buffer area, and the storage allocation module structure is divided into two parts; as shown in fig. 9, one part is a storage computation module, which is located in part in the gNB-CU; the other part is dynamic memory space, and the module part is located in gNB-DU. The function of the storage calculation module is to calculate the size of the storage space allocated by the 5G base station for each UE, and since the data flow of uplink and downlink services is dynamically changed, the buffer reported data received by the 5G base station and the data flow of downlink services are also dynamically changed, the calculation module needs to be capable of calculating the dynamic flow data, and the allocable storage space of the gNB-DU can be obtained based on the F1 interface signaling flow. And allocating dynamic storage space for the UE by adopting a certain strategy based on the acquired information. gNB-CU is a 5G base station central unit; the gNB-DU is a 5G base station distribution unit.
