Description
Technical Field
The present invention relates to the field of communications technologies, and in particular, to a cell access control method, apparatus, and base station.
Background
The number of UEs (User Equipment) that a single Cell (Cell) of a base station can accommodate is always limited. In the general practice of the wireless communication system in the aspect of Access Control (AC), the Access to the UE is generally controlled by the UE number, the DRB (Data Radio Bearer) number, and the GBR (Guaranteed Bit Rate) Rate, so as to prevent the service upper limit that can be provided by a cell from being exceeded and to affect the existing UE. But existing access control methods still result in saturated access.
The saturated access can be divided into the following scenarios: the first situation is that a large number of legal UEs reside in a certain cell in a centralized way to perform wireless access, a base station performs access control according to the existing access control method, but for certain access types, priority cannot be distinguished, so that the UEs needing priority access cannot preferentially access a wireless network in a saturated scene; the second situation is that a large number of illegal UEs exist and reside in a certain cell for saturated access, and wireless resources are seized, so that legal UEs cannot normally access the network; the third situation is that the UE is in a remote location and accessed in a shielded or wireless signal interference situation, and because of the signal strength and quality, the UE cannot access the network all the time, and tries to access for a long time, thereby occupying a large amount of wireless resources.
The saturated access not only causes the wireless access resources to be completely occupied, but also the UE which should be preferentially accessed cannot access the network, and the long-time wireless access occupies the system and the wireless resources, thereby influencing the normal service use of the UE on the network. The existing access control can only ensure the service use of the UE on the network in a limited way, and the saturated access can occupy the system resource and reduce the normal service experience of the UE on the network. In addition, some UEs requiring preferential access cannot access the wireless network due to saturated access, so that the demand of high priority cannot be responded, and user experience is affected.
In summary, the existing cell access control method has the defect that it is difficult to ensure the normal service of the legal UE.

Specific meanings of the above terms in the embodiments of the present invention can be understood in specific cases by those of ordinary skill in the art.
In order to overcome the above problems in the prior art, the present invention provides a cell access Control method, device and base station, and the inventive concept is that a cell access Control device independent of a CU-CP (Control Unit-Control Plane) or a CCU (Central Control Unit) processes an access request of a UE to complete access of the UE, and even in a saturated access scenario, the UE that is performing a normal service through the CU-CP or the CCU is not affected, thereby ensuring a normal service of a valid UE and improving quality and experience of a communication service.
Fig. 1 is a flowchart illustrating a cell access control method according to the present invention. The cell access control method according to the embodiment of the present invention is described below with reference to fig. 1. As shown in fig. 1, the method includes: step 101, receiving an access request of a target UE; the access request is used for requesting access to the target cell.
Specifically, an execution subject of the cell access control method provided by the embodiment of the present invention is a cell access control apparatus. The cell access control device belongs to a kind of CP-AC (control plane-access control) device, independent of CU-CP (control unit-control plane) or CCU (central control unit) included in the base station. The cell access control device is used for processing the UE process before the access request is completed, and comprises a random access process and other subsequent processes. The base station can be applied to but not limited to a 4G communication system and a 5G communication system.
The target UE sends an access request for accessing the target cell to the base station, and the base station can receive the access request through the cell access control device.
The Cell access Control device may communicate with the CU-CP or the CCU through an SCTP link based on a Stream Control Transmission Protocol (SCTP) to transmit configuration of relevant parameters of a Cell, an RRC (Radio Resource Control) and an RRM (Radio Resource Management). Based on relevant parameter configuration of Cell, RRC and RRM, the Cell access control device may process the access request.
There may be two results in processing the access request: the access is successful, namely the target cell is successfully accessed; and access failure, i.e. failure to access the target cell.
102, under the condition that the continuous access failure times of the target UE reach the target times, sending an SIB1 message carrying information of a target time period to the target UE so that the target UE does not initiate an access request in the target time period;
specifically, in the embodiment of the present invention, an information element regis failurecontrol is added to the SIB1 message. According to networking requirements, two parameters, namely, the regis failurecount and the regis failuretime, may be configured in the cell regis failurecontrol, that is, the cell regis failurecontrol may include at least two parameters: regis FailureCount and Regis FailWaitTime. The cell RegisFailureControl can be applied to, but not limited to, a 4G communication system and a 5G communication system.
The parameter RegisFailUreCount represents the target number of times, and RegisFailWaitTime represents the duration of the target time period.
The target times can be preset according to actual conditions. The examples of the present application are not particularly limited with respect to the specific value of the target number of times.
Alternatively, the target number of times may be 5 times.
The duration of the target time period can be preset according to actual conditions. The specific value of the duration of the target time period is not specifically limited in the embodiments of the present application.
In case that the target UE fails to access the target cell successfully, the number of times of continuous access failure of the target UE may be counted.
If the number of times of continuous access failure does not reach the target number of times, the target UE can initiate the process of requesting to access the target cell by sending the access request again.
If the number of consecutive access failures reaches the target number, the cell access control device may return an SIB1 message to the target UE. The information element of the SIB1 message includes the above-mentioned information element RegisFailureControl.
After receiving the SIB1 message returned by the cell access control device, the target UE may immediately respond, and no access request is sent on any network within a target time period (RegisFailWaitTime) with the current time as the start time and the time as the target time period.
In the embodiment of the invention, by adding the RegisFailureControl cell, the waiting time can be applied to the UE with continuous registration failure, the UE is prevented from frequently initiating an invalid registration request process, and the second situation and the third situation of saturated access can be effectively responded. NAS (non-access stratum) related description in a 3GPP protocol can prevent an access request from being sent after an access failure exceeds 5 times through a counter count and a related timer, and the number of times of the access request is limited.
In the embodiment of the invention, under the condition that the continuous access failure times of the target UE reach the target times, the target UE is sent with the SIB1 message carrying the information of the target time period, so that the target UE does not initiate an access request in the target time period, thereby avoiding the frequent access of illegal UEs and UEs with poor signal quality, increasing the waiting time of legal UEs, reducing the access load pressure of a base station, better ensuring the normal service of the legal UEs and avoiding the reduction of the service quality of the normal UEs on the network.
Based on the content of any of the above embodiments, after receiving the access request of the target UE, the method further includes: and under the condition that the target cell meets the saturated access, determining the processing sequence of each UE which has sent the access request and does not finish accessing the target cell.
Specifically, whether the target cell satisfies the condition of the saturated access may be determined based on at least one of a sum of UEs that have completed accessing the target cell and UEs that have transmitted the access request but have not completed accessing the target cell, and a target performance parameter of the target cell.
For example, if the target performance parameter a of the target cell exceeds a first target threshold and/or the target performance parameter a of the target cell is lower than a second target threshold, it may be determined that the target cell satisfies the condition of saturated access. The first target threshold and the second target threshold can be preset according to actual conditions. For specific values of the first target threshold and the second target threshold, the embodiments of the present application are not particularly limited.
Under the condition that the target cell meets the saturated access, the cell access control device can enter a saturated access mode, for each UE which has sent the access request and does not finish accessing the target cell, the priority of the UE can be determined according to a pre-stored priority list, and then the access request sent by each UE is processed from high to low according to the priority of the UE, so that the first condition of the saturated access can be effectively dealt with.
The priority list may store mapping relationships between UEs of various access types and priorities.
The UEs are arranged in the order of priority from high to low, i.e. the processing order.
And processing the access request sent by each UE based on the processing sequence.
Specifically, based on the processing sequence, the access requests sent by the UEs are processed, and the UE with the high priority access type can preempt the access opportunity of the UE with the low priority access type, and control the access of the UE with the low priority access type, so that the access of the UE with the low priority access type fails.
Optionally, the UE with the high priority access type preferentially accesses the network; and each UE of the low-priority access type is sequentially accessed or refused to be accessed according to the priority sequence.
For any UE in the UEs that have sent the access request and have not completed accessing the target cell, the cell access control device may send an RRC Release message to each UE with a priority lower than that of the UE in the process of processing the access request of the UE, interrupt the process of accessing the target cell by each UE, and leave an access opportunity for other UEs with high priorities.
The embodiment of the invention preferentially accesses the UE with the high priority type and controls the access of the UE with the low priority type under the condition that the target cell meets the saturated access, thereby better ensuring the normal service of the legal UE and realizing the timely response of the access requirement of the UE with the high priority.
Based on the content of any of the above embodiments, determining that the target cell satisfies the condition of saturated access includes: and if the number of the UE which finishes accessing the target cell and has sent the access request and does not finish accessing the target cell exceeds the target number is judged and known, determining that the target cell meets the condition of saturated access.
Specifically, the sum of the number of UEs that have completed accessing the target cell and UEs that have sent access requests but have not completed accessing the target cell is obtained.
And judging whether the sum of the number of the UE which finishes accessing the target cell and the number of the UE which has sent the access request but does not finish accessing the target cell reaches the target number.
Alternatively, the target number may be preset according to actual conditions. The examples of the present application are not particularly limited with respect to the specific values of the target amounts.
If the target number is reached, determining that the target cell meets the condition of saturated access; if the target number is reached, it may be determined that the target cell does not satisfy the condition of the saturated access.
The embodiment of the invention can more accurately determine whether the target cell is in saturation access or not by judging whether the number of the UE which finishes accessing the target cell and has sent the access request and does not finish accessing the target cell exceeds the target number or not and determining whether the target cell meets the condition of saturation access or not, thereby timely carrying out cell access control, avoiding the phenomenon that the UE with high priority access type cannot access the target cell because a large number of the UE with low priority access type access into the target cell, better ensuring the normal service of the UE with high priority access type, realizing timely responding to the UE high priority access requirement and improving the quality and experience of communication service.
Based on the content of any of the above embodiments, determining a processing order of each UE that has sent an access request and has not completed accessing a target cell specifically includes: the processing order is determined based on the RRC setting request message transmitted by each UE.
Specifically, for each UE that has transmitted an access Request and has not completed accessing the target cell, the processing order of each UE may be determined based on an RRC Setup Request (RRC Setup Request) message transmitted by each UE.
Optionally, the UEs may be sorted based on the essablishmentcause information carried in the RRC Setup Request message.
The EstablishmentCause information can comprise mergency, highPrioriyAccess, mt-Access, mo-Signalling, mo-Data, mo-VoiceCall, mo-VideoCall, mo-SMS, mp-PrioriyAccess and mcs-PrioriyAccess, and the like, and the priority is from high to low, namely emergency, highPrioriyAccess, mo-Signaling, mo-VoiceCall, mo-SMS, mcs-PrioriyAccess, mp-PrioriyAccess, mo-VideoCall, mt-Access and mo-Data.
For example, the information of the instablessmentaue carried in the RRC Setup Request messages sent by UE1, UE2, and UE3 are mo-SMS, highpriorityacess, and mo-VideoCall, respectively, and then it may be determined that the processing order of UE1, UE2, and UE3 is: UE2, UE1, UE3.
The embodiment of the invention determines the processing sequence based on the RRC setting request message sent by each UE, can ensure that the UE with the high priority access type is preferentially accessed to the target cell, and can respond to the access requirement of the UE with the high priority in time, thereby better ensuring the normal service of the UE with the high priority access type and improving the quality and experience of communication service.
Based on the content of any of the above embodiments, the target number is determined based on the maximum number of UEs accommodated by the target cell and the target ratio.
Specifically, the target number may be determined based on a maximum number of target cells accommodating UEs (Thresh-H) and a target ratio (Percent-H).
The maximum number of UEs accommodated by the target cell is determined according to the design criteria of the target cell.
The target proportion can be preset according to the actual situation. For example, the target proportion is 90%. The examples of the present application are not particularly limited with respect to the specific value of the target ratio.
The embodiment of the invention determines the target number based on the maximum number and the target proportion of the target cell for accommodating the UE, and can more accurately determine whether the target cell is in saturation access or not based on the target number, thereby timely carrying out cell access control, avoiding the phenomenon that the UE in a high priority access type cannot be accessed into the target cell because a large number of the UE in a low priority access type is accessed into the target cell, timely responding to the access requirement of the UE in a high priority, better ensuring the normal service of the UE in the high priority access type, and improving the quality and experience of communication service.
Based on the content of any of the above embodiments, after receiving the access request of the target UE, the method further includes: and transferring the UE context of the target UE to the control unit under the condition that the target UE is successfully accessed into the target cell.
Specifically, after the target UE successfully accesses the target cell, the cell access control apparatus may transfer the UE CONTEXT (UE CONTEXT) of the target UE to the control unit.
And after the UE context of the target UE is transferred to the control unit, processing the normal service requirement of the subsequent target UE by the control unit.
Optionally, after the UE context of the target UE is transferred to the control unit, the cell access control apparatus may delete the UE context of the target UE stored in the cell access control apparatus.
Optionally, for a 5G base station, the control unit is CU-CP; for a 4G base station, the control unit is a CCU.
According to the embodiment of the invention, after the target UE is successfully accessed into the target cell, the UE context of the target UE is transferred to the control unit, the access process of the UE is separated from the service processing process, the saturated access can be prevented from occupying system resources, the service of the accessed UE is influenced, the normal service of legal UE can be better ensured, and the reduction of the normal UE service quality in the network can be avoided.
