Description

UE RRC state determination method and device

technical field

Background technique

At present, in the 3GPP (3rd Generation Partnership Project, 3rd Generation Partnership Project) protocol, it is defined that the RRC (Radio Resource Control, Radio Resource Control) connection release in the 5G (5-Generation mobile communication technology, fifth generation mobile communication technology) network is released The RRC state accessed by the UE after the UE (User Equipment, user equipment) includes: the RRC IDLE state or the RRC INACTIVE state. If the UE accesses the RRC IDLE state, when the UE has service data to send again, the RRC connection needs to be re-established, including the air interface connection and the NG interface connection. The above connection process is complicated by the signaling interaction between the UE and the core network. , so the timeliness of data transmission is poor; if the UE accesses the RRC INACTIVE state, the RRC only needs to release the air interface connection, and the gNB (5G base station) still saves the context information and security information of the UE. When the UE needs to send services again , the UE only needs to send an RRC connection request to the gNB to establish a connection. The above-mentioned connection process has less signaling interaction, so the connection establishment speed is faster, thereby ensuring the timeliness of data transmission. However, in practice, since the UE accesses the RRC INACTIVE state and does not release the NG interface connection, if all UEs access the RRC INACTIVE state, a large amount of NG interface resources are occupied. For UEs that do not need to access the network frequently, this This approach will obviously cause unnecessary waste of network resources.

It can be seen that, after the UE is released from the RRC connection, determining which RRC state the UE accesses to ensure the timeliness of data transmission and reduce the waste of network resources has become an urgent problem to be solved at present.

Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

Currently, in the 5G network, after the RRC connection is released, the UE can enter the RRC IDLE state or the RRC INACTIVE state. In the actual situation, the following problems arise when the UE accesses the RRC IDLE state and the UE accesses the RRC INACTIVE state: If the UE accesses the RRC IDLE state, the UE needs to re-establish the air interface connection and the NG interface (ie: 5G wireless connection) to re-establish the RRC connection. The interface between the access network and the 5G core network) is connected, and the establishment of the above-mentioned connection requires multiple subjects (including UE, RAN (Radio Access Network, radio access network), AMF (Authentication Management Function, authentication management function), UPF (User Plane Function, new I-UPF), SMF (Session Management Function, session management function), UPF (old I-UPF), UPF (PSA), PCF (Packet Control Function, packet control function), and The signaling interaction between AUSF (Authentication Server Function, authentication server function), the number of signaling exchanges is large, the interaction process is complex, and the timeliness of data transmission is poor; if the UE accesses the RRC INACTIVE state, the RRC is only released. In the air interface connection, the gNB saves the context information and security information of the UE. Therefore, when the UE re-establishes the RRC connection, the RRC connection can be quickly established with only a few signaling, thereby ensuring the timeliness of data transmission and saving power for the UE. However, in practice, since the NG interface connection is not released when the UE accesses the RRC INACTIVE state, and some UEs do not need to re-establish the RRC connection within a short time after the RRC connection is released, these UEs do not need to use the NG interface but occupy a large amount of In this case, the UE should access the RRC IDLE state instead of the RRC INACTIVE state; when the UE moves, if the UE moves from an RNA (RAN (Radio Access) Network, radio access network)-based Notification Area, sequence-based notification area) moves to another RNA, UE's uplink information and security information need to be transferred between gNBs of different RNAs, which requires a lot of Xn interface (using For connecting to NG-RAN nodes) resources, so for UEs that move fast and do not need to establish RRC connections frequently, the UE should access the RRC IDLE state instead of the RRC INACTIVE state. However, in practical situations, There is no corresponding determination method for when the UE should access the RRC IDLE state or the RRC INACTIVE state, resulting in transmission between the UE and the network. The problem of poor timeliness or serious waste of network resources.

Based on the above problems, the present invention provides a UE RRC state determination method, as shown in FIG. 1 , the method includes:

Step S110: Acquire service data of an application running in the UE when the RRC connection releases the UE.

The service data may include: all data related to the service of the application running in the UE, and may specifically involve: service-related time data, service-related location data, service-related scene information data, and service-related service data types , business-related business usage data, business-related business load data, and so on. In a specific implementation, the service data may be service data within a preset time period, and the foregoing preset time period may be set by those skilled in the art according to actual conditions, which is not limited in the present invention.

There are various ways to obtain service data. For example, the service data of the above application can be obtained directly from the UE; The application ID of the application program obtains the business data of the application program from the network side. The acquisition method of acquiring the service data of the application program from the network side can achieve the purpose of acquiring the service data of the application program in batches from the network side, thereby improving the efficiency of acquiring the service data. In specific implementation, preferably, the ID of the application carried in the PDCP (Packet Data Convergence Protocol, Packet Data Convergence Protocol) header can be obtained from the network slice that processes the service data of the application run by the UE, and the ID of the application can be obtained from the network slice according to the ID of the application. to get the business data for the application.

Of course, it can be understood that the above-mentioned acquisition methods are only exemplary. In specific implementation, the present invention can also acquire the above-mentioned business data by other acquisition methods other than the above-mentioned acquisition methods, as long as the business data of the application program can be acquired.

Step S120: Input the business data into a preset business data prediction model to obtain the predicted business data of the application.

The preset business data prediction model may be used to determine the predicted business data of the application according to the input business data. In specific implementation, the preset business data prediction model may use data mining algorithm or machine learning algorithm, such as Apriori algorithm, K-Means algorithm, theoretical reasoning algorithm, Laplace support vector machine, etc. The specific algorithm used by the data prediction model is not limited.

The predicted service data may at least include: the first access time interval of the UE accessing the network next time, the first access frequency of the UE within the preset time interval after the RRC connection is released, and the first access frequency after the UE accesses the application program. Moving speed. The first access time interval is the time interval between the time when the UE is predicted to release the RRC connection and the time when the UE accesses the network next time. For example, if the first access time interval is 45 seconds, it can be regarded as the RRC connection release. At the 45th second after the UE needs to re-access the network, the first access time interval can indicate whether the UE needs to quickly re-access the network after the RRC connection is released; The frequency at which the UE may re-access the network within the time interval, that is, the number of times the UE may re-access the network within a unit time within the preset time interval; for example, if the preset time interval is 2 minutes, the first access frequency is 3 , then it can be predicted that the UE accesses the network 3 times per minute within 2 minutes after the RRC connection is released. The second access network, the preset time interval can be set by those skilled in the art according to the actual situation, which is not limited in the present invention; Set the movement speed of the UE within the duration, the preset duration can be set by those skilled in the art according to the actual situation, which is not limited in the present invention), the first movement speed can represent the movement state of the UE and the movement of the UE after the UE accesses the network next time For example, if the first moving speed is 0, it means that the UE is stationary; if the first moving speed is 60 km/h, it means that the UE is moving and moving fast.

Of course, it can be understood that the predicted business data may also include other data other than the data listed above, such as the business occurrence time, such as the peak time or low peak time of the business occurrence, etc.; the business occurrence location, such as the business occurrence place, Cells covered by UE signals when the service occurs; service occurrence scenarios, such as vehicle driving records, medical timing monitoring, smart home control, etc.; service data types, such as voice service, video service, data service, etc.

Step S130: Determine the RRC state accessed by the UE according to the predicted service data; the RRC state includes: RRC IDLE state or RRC INACTIVE state.

Specifically, this step can be performed in many ways. For example, the preset conditions for accessing the RRC IDLE state or the preset conditions for accessing the RRC INACTIVE state may be preset, and then according to the first moving speed, the first access time interval, the first access frequency and the above preset The condition determines the RRC state of the UE access. For example, the preset conditions for accessing the RRC IDLE state can be preset, and then it is determined whether the first moving speed, the first access time interval, and the first access frequency meet the above-mentioned preset conditions for accessing the RRC IDLE state. If it is satisfied, then the UE is connected to the RRC IDLE state, otherwise, the UE is connected to the RRC INACTIVE state; or, similarly, the preset conditions that satisfy the access to the RRC INACTIVE state can also be preset, and then the first moving speed and the first access time can be determined. Whether the interval and the first access frequency meet the above preset conditions for accessing the RRC INACTIVE state, if so, the UE is connected to the RRC INACTIVE state, otherwise, the UE is connected to the RRC IDLE state. In specific implementation, the setting of the above-mentioned preset conditions may be set by those skilled in the art according to the actual situation, which is not limited in the present invention.

In a preferred manner, as shown in FIG. 2 , the process of determining the RRC state accessed by the UE according to the predicted service data may be as follows:

Step S210: Determine whether the first movement speed is greater than a preset UE movement speed preset threshold; if the determination result is yes, then step S220 is performed; if the determination result is no, step S230 is performed.

Step S220: Determine whether the first access time interval is less than the preset first access time interval threshold or whether the first access frequency is greater than the preset first access frequency threshold; if the determination result is yes, perform step S240 ; If the judgment result is no, execute step S250.

Step S230: Determine whether the first access time interval is less than the preset second access time interval threshold or whether the first access frequency is greater than the preset second access frequency threshold; if the determination result is yes, then perform step S240 ; If the judgment result is no, execute step S250.

Step S240: determine that the UE accesses the RRC INACTIVE state.

Step S250: Determine the UE access RRC IDLE state.

The first access time interval threshold is smaller than the second access time interval threshold, and the first access frequency threshold is greater than the second access frequency threshold. The first access time interval threshold, the first access frequency threshold, the second access time interval threshold and the second access frequency threshold can be set by those skilled in the art according to actual conditions, which are not limited in the present invention.

In the present invention, through steps S210-S250, the UEs that need to re-access the network in a short time after the RRC connection is released and/or the UEs that need to frequently access the network after the RRC connection is released can be brought into the RRC INACTIVE state; After the RRC connection is released, the UE does not need to re-access the network in a short time and/or the UE that does not need to frequently access the network after the RRC connection is released accesses the RRC IDLE state, thereby effectively ensuring the timeliness of data transmission; at the same time, the above process is also based on the first The movement speed sets different thresholds for the time interval and access frequency of the UE re-accessing the network. For example, when the first movement speed is greater than the preset UE movement speed preset threshold, the UE movement speed is faster at this time, and the RNA(RAN() Radio Access Network (Radio Access Network)-based Notification Area) has a high frequency and consumes a lot of UE context delivery resources, so a small threshold is set for the time interval for re-accessing the network for this type of service And set a larger threshold for the access frequency of such services, so that UEs with higher access frequency and shorter time interval accessing the network are preferentially connected to the RRC INACTIVE state, which reduces network resources while ensuring the timeliness of data transmission. Waste, so that the timeliness of network data transmission and the utilization of network resources to achieve the maximum balance.

Further, preferably, in order to improve the accuracy of the predicted service data in the present invention, after step S230 is executed, the actual service data of the UE's next access to the network can be further obtained; that is, the actual service data when the UE accesses the network next time. The second access time interval, the actual second access frequency of the UE within the preset time interval after the RRC connection is released next time, and the actual second movement speed of the UE after the UE accesses the network next time (which can be a preset duration The actual moving speed of the UE, the preset duration can be set by those skilled in the art according to the actual situation, which is not limited in the present invention), and then the preset service data prediction model is adjusted according to the actual service data of the UE, that is: according to the actual service data of the UE. The preset algorithm inputs the acquired actual service data (that is, the above-mentioned second access time interval, second access frequency, and second moving speed) into the preset service data prediction model, and uses the preset algorithm and actual service data to predict the prediction model. The preset service data prediction model (that is, the first access time interval, the first access frequency, and the first moving speed) is trained and corrected to improve the predicted service data (that is, the output of the preset service data prediction model). : the accuracy of the first access time interval, the first access frequency, and the first movement speed). In the specific implementation, the algorithm used to adjust the preset business data prediction model can be set by those skilled in the art according to the actual situation. limited.

More preferably, in order to more accurately determine the RRC state accessed by the UE, the first access time interval, the first access frequency, and the first moving speed can also be adjusted in real time according to the service occurrence time.

For example: if the peak time of service occurrence and the low-peak time of service occurrence are further predicted in step S220, the preset threshold value of UE movement speed can be reduced and the first access time interval threshold value can be increased at the peak time of service occurrence. and the second access time interval threshold, as well as reducing the first access frequency threshold and the second access frequency threshold, so that the UE can more easily access the RRC INACTIVE state during the peak time of service occurrence, ensuring the timeliness of network data transmission, etc. . Of course, it can be understood that the above adjustment method is only exemplary, and the real-time adjustment method of the first access time interval, the first access frequency, and the first moving speed according to the service occurrence time can be performed by those skilled in the art according to the actual situation. settings, including but not limited to the adjustment methods listed above.

Of course, it can be understood that, in the specific implementation, the above-mentioned service occurrence time can also be replaced with other predicted service data other than the first access time interval, the first access frequency, and the first moving speed, such as the service occurrence location ( The first access time interval, the first access frequency, and the first moving speed are adjusted in real time, such as whether the UE is in a hotspot cell), the service occurrence scenario (such as whether the UE is in a high-speed vehicle such as a high-speed rail), etc. The adjustment mode can be set by those skilled in the art according to the actual situation, which is not limited in the present invention.
