Description
Technical Field
The embodiment of the invention relates to the technical field of communication, in particular to a method and a device for determining a UE RRC state.
Background
Currently, in 3GPP (3rd Generation Partnership Project) protocol, an RRC (Radio Resource Control) state of UE access after an RRC (Radio Resource Control) connection in a 5G (5-Generation mobile communication technology) network releases a UE (User Equipment) is defined, and the RRC state includes: RRC IDLE state, or RRC INACTIVE state. If the UE is accessed to the RRC IDLE state, when the UE has service data to be sent again, RRC connection needs to be reestablished, wherein the RRC connection comprises air interface connection and NG interface connection, and the timeliness of data transmission is poor due to the fact that the signaling interaction process between the UE and a core network is complex in the connection process; if the UE is in the RRC INACTIVE state, the RRC only needs to release the air interface connection, and the gNB (5G base station) still stores the context information and security information of the UE, and when the UE has a service to send again, the UE only needs to send an RRC connection request to the gNB to establish a connection. However, in practical situations, since the NG interface connection is not released in the UE access RRC INACTIVE state, if a large amount of NG interface resources are required to be occupied by accessing all UEs in the RRC INACTIVE state, such an approach obviously causes unnecessary waste of network resources for UEs that do not need to access the network frequently.
Therefore, after the RRC connection releases the UE, determining what RRC state the UE accesses to ensure timeliness of data transmission and reduce waste of network resources becomes a problem that needs to be solved at present.

It is to be understood that the embodiments described are only a few embodiments of the present invention, and not all embodiments.

In the embodiments of the present invention, words such as "exemplary" or "for example" are used to mean serving as examples, illustrations or descriptions. Any embodiment or design described as "exemplary" or "e.g.," an embodiment of the present invention is not necessarily to be construed as preferred or advantageous over other embodiments or designs.

Currently, in a 5G network, after the RRC connection is released, the UE may be switched to an RRC IDLE state or RRC INACTIVE state. In practical situations, the following problems occur when the UE accesses the RRC IDLE state and the UE is accessed after accessing the RRC INACTIVE state: if the UE accesses the RRC IDLE state, the UE reestablishes the RRC connection and needs to reestablish an air interface connection and an NG interface (i.e., an interface between the 5G Radio Access Network and the 5G core Network), and the establishment of the above connections needs to perform signaling interaction between a plurality of main bodies (including the UE, RAN (Radio Access Network), AMF (Authentication Management Function), UPF (User Plane Function, new I-UPF), SMF (Session Management Function), UPF (old I-UPF), UPF (psa), PCF (Packet Control Function), and AUSF (Authentication Server Function), which have a large number of signaling interactions and a complicated interaction process and have poor data transmission timeliness, and if the UE accesses the RRC RRC INACTIVE state, the RRC connection is released, and only the air interface connection and the safety information of the UE are saved, therefore, the RRC connection can be quickly established by only a few signaling when the UE reestablishes the RRC connection, so that the timeliness of data transmission is ensured, and the aim of saving electricity for the UE can be fulfilled. However, in practical cases, 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 being released by the RRC connection, these UEs do not need to use the NG interface but occupy a large amount of NG interface resources, which results in a large amount of NG interface resource waste, in which case, the UE should access the RRC IDLE state, and should not access the RRC INACTIVE state; when the UE moves, if the UE moves from one RNA (Radio Access Network) -based Notification Area to another RNA, uplink information and security information of the UE need to be transferred between gnbs of different RNAs, which requires consuming a large amount of Xn interface (for connecting NG-RAN nodes) resources, so for the UE that has a fast moving speed and does not need to frequently establish an RRC connection, the UE should Access the RRC IDLE state, but should not Access the RRC INACTIVE state. However, in practical situations, there is no corresponding determination method for the situation in which the UE should access the RRC IDLE state or the access RRC INACTIVE state, resulting in a problem of poor transmission timeliness or a serious waste of network resources between the UE and the network.
Based on the existing problems, the present invention provides a method for determining the RRC state of a UE, as shown in fig. 1, the method includes:
step S110: and acquiring service data of an application program operated 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 may specifically relate to: time data related to the service, location data related to the service, scene information data related to the service, a type of service data related to the service, service usage data related to the service, and service load data related to the service, and the like. In a specific implementation, the service data may be service data within a preset time period, and the preset time period may be set by a person skilled in the art according to an actual situation, which is not limited by the present invention.
There are various ways to obtain service data, for example, service data of the application program may be directly obtained from the UE; alternatively, the application identifier (for example, an ID of the application) of the application may be obtained from the UE, and then the service data of the application may be obtained from the network side according to the application identifier of the application. The method for 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 from the network side in batch, so that the efficiency of acquiring the service data can be improved. In specific implementation, preferably, the ID of the application carried by a Packet Data Convergence Protocol (PDCP) header may be obtained from a network slice that processes service Data of the application run by the UE, and the service Data of the application may be obtained from the network slice according to the ID of the application.
Of course, it is to be understood that the above described acquisition is merely exemplary. In a specific implementation, the present invention may also adopt other acquisition manners besides the above acquisition manner to acquire the service data, as long as the service data of the application program can be acquired.
Step S120: and inputting the service data into a preset service data prediction model to obtain the predicted service data of the application program.
The preset business data prediction model can be used for determining the predicted business data of the application program according to the input business data. In specific implementation, the preset service data prediction model may adopt a data mining algorithm or a machine learning algorithm, such as an Apriori algorithm, a K-Means algorithm, a theoretical reasoning algorithm, a laplacian support vector machine, and the like.
Predicting traffic data may include at least: the UE accesses a first access time interval of a network next time, a first access frequency of the UE in a preset time interval after RRC connection release and a first moving speed of the UE after accessing an application program. For example, if the first access time interval is 45 seconds, it can be regarded that the UE needs to re-access the network after the RRC connection releases the UE in 45 seconds, and the first access time interval may indicate whether the UE needs to quickly re-access the network after the RRC connection releases the UE; the first access frequency is a predicted frequency that the UE possibly re-accesses the network within a preset time interval after the RRC connection releases the UE, namely the number of times that the UE possibly re-accesses the network within unit time within the preset time interval; for example, if the preset time interval is 2 minutes and the first access frequency is 3, the frequency of the UE accessing the network within 2 minutes after the RRC connection releases the UE may be predicted to be 3 times/minute, in a specific implementation, the first access frequency may indicate whether the UE needs to access the network for multiple times within the preset time interval after the RRC connection releases the UE, and the preset time interval may be set by a person skilled in the art according to an actual situation, which is not limited by the present invention; the first moving speed is specifically a moving speed of the UE after the UE accesses the network next time (the moving speed of the UE may be a predicted moving speed of the UE within a preset time, and the preset time may be set by a person skilled in the art according to an actual situation, which is not limited by the present invention), and the first moving speed may represent a motion state of the UE and a moving speed of the UE after the UE accesses the network next time, for example, if the first moving speed is 0, it is determined that the UE is stationary; if the first moving speed is 60 km/h, it means that the UE is moving and the moving speed is faster.
Of course, it is understood that the predicted traffic data may also include other data than those listed above, such as the time of occurrence of a traffic, e.g., the peak time or the low peak time of occurrence of a traffic, etc.; a service occurrence location, such as a location where the service occurs, a cell covered by a signal of the UE when the service occurs, and the like; service occurrence scenes such as vehicle driving records, medical timing monitoring, intelligent home control and the like; service data types such as voice service, video service, data service, etc.
Step S130: determining the RRC state accessed by the UE according to the predicted service data; the RRC states include: RRC IDLE state, or RRC INACTIVE state.
Specifically, the execution manner of this step may be various. For example, a preset condition for accessing to the RRC IDLE state or a preset condition for accessing to the RRC INACTIVE state may be preset, and then the RRC state accessed by the UE may be determined according to the first moving speed, the first access time interval, the first access frequency, and the preset conditions. For example, preset conditions meeting the RRC IDLE state access may be preset, and then it is determined whether the first moving speed, the first access time interval, and the first access frequency meet the preset conditions meeting the RRC IDLE state, if yes, the UE is accessed to the RRC IDLE state, otherwise, the UE is accessed to the RRC INACTIVE state; or, similarly, it may also be preset to set a preset condition that the access RRC INACTIVE state is satisfied, and then determine whether the first moving speed, the first access time interval, and the first access frequency satisfy the preset condition of the access RRC INACTIVE state, if so, access the UE to the RRC INACTIVE state, otherwise, access the RRC IDLE state. In a specific implementation, the setting of the preset condition may be set by a person skilled in the art according to actual situations, and the present invention is not limited to this.
In a preferred manner, referring to fig. 2, the process of determining the RRC state accessed by the UE according to the predicted traffic data may be:
step S210: judging whether the first moving speed is greater than a preset UE moving speed preset threshold value or not; if yes, go to step S220; if the determination result is negative, step S230 is executed.
Step S220: judging whether the first access time interval is smaller than a preset first access time interval threshold or whether the first access frequency is larger than a preset first access frequency threshold; if yes, go to step S240; if the determination result is negative, step S250 is executed.
Step S230: judging whether the first access time interval is smaller than a preset second access time interval threshold or whether the first access frequency is larger than a preset second access frequency threshold; if yes, go to step S240; if the determination result is negative, step S250 is executed.
Step S240: the UE access RRC INACTIVE status is determined.
Step S250: and determining that the UE accesses the RRC IDLE state.
Wherein the first access time interval threshold is less 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 may be set by those skilled in the art according to practical situations, and the present invention is not limited thereto.
In the invention, through steps S210 to S250, the UE which needs to re-access the network in a short time after the RRC connection is released from the UE and/or needs to frequently access the network after the RRC connection is released from the UE can be accessed into RRC INACTIVE state; the UE which does not need to be re-accessed to the network in a short time after the RRC connection is released and/or does not need to be frequently accessed to the network after the RRC connection is released is accessed to the RRC IDLE state, so that the timeliness of data transmission is effectively ensured; meanwhile, the process also sets different thresholds for the time interval and the access frequency of the UE to re-access the network according to the first moving speed, for example, when the first moving speed is greater than a preset UE moving speed threshold, the UE moving speed is faster, the frequency of updating RNA (Radio Access Network ) -based Notification Area (sequence-based Notification Area) is higher and the transmission resource consuming the UE context is more, a smaller threshold is set for the time interval for such traffic to re-access the network and a larger threshold is set for the access frequency for such traffic, so that the UE with higher access frequency and shorter time interval for accessing the network is preferentially accessed into the RRC INACTIVE state, the timeliness of data transmission is guaranteed, meanwhile, the waste of network resources is reduced, and the timeliness of network data transmission and the utilization rate of network resources are balanced to the maximum.
Further, preferably, in order to improve the accuracy of predicting the service data in the present invention, after the step S230 is completed, the actual service data of the UE accessing the network next time may be further obtained; namely: the actual second access time interval when the UE accesses the network next time, 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 moving speed of the UE after the UE accesses the network next time (which may be the actual moving speed of the UE within the preset time duration, and the preset time duration may be set by a person skilled in the art according to the actual situation, which is not limited by the present invention), and then the preset service data prediction model is adjusted according to the actual service data of the UE, that is: inputting the obtained actual service data (i.e. the second access time interval, the second access frequency, and the second moving speed) into a preset service data prediction model according to a preset algorithm, and training and correcting the preset service data prediction model (i.e. the first access time interval, the first access frequency, and the first moving speed) through the preset algorithm and the actual service data so as to improve the accuracy of the predicted service data (i.e. the first access time interval, the first access frequency, and the first moving speed) output by the preset service data prediction model. In specific implementation, the algorithm used for adjusting the preset service data prediction model may be set by a person skilled in the art according to actual conditions, for example, an artificial intelligence algorithm such as a deep learning algorithm and a neural network algorithm may be used, which is not limited in the present invention.
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 may be adjusted in real time according to the service occurrence time.
For example, the following steps are carried out: if the peak time of the traffic occurrence and the low peak time of the traffic occurrence are further predicted in step S220, the UE moving speed preset threshold may be decreased during the peak time of the traffic occurrence, and the first access time interval threshold and the second access time interval threshold may be increased, and the first access frequency threshold and the second access frequency threshold may be decreased at the same time, so that the UE may be more easily accessed to the RRC INACTIVE state during the peak time of the traffic occurrence, and the timeliness of network data transmission may be ensured, for example. Of course, it is understood that the above adjustment manners are only exemplary, and the manner of adjusting the first access time interval, the first access frequency, and the first moving speed in real time according to the service occurrence time may be set by those skilled in the art according to practical situations, including but not limited to the above-listed adjustment manners.
Of course, it is understood that in an embodiment, the service occurrence time may be replaced by other predicted service data besides the first access time interval, the first access frequency, and the first moving speed, such as a service occurrence location (for example, whether the UE is in a hot cell), a service occurrence scene (for example, whether the UE is in a high-speed vehicle such as a high-speed rail), and the like, to perform real-time adjustment on the first access time interval, the first access frequency, and the first moving speed, and a real-time adjustment manner may be set by a person skilled in the art according to an actual situation, which is not limited by the present invention.
