Description
Technical Field
The present invention relates to the field of communications technologies, and in particular, to a method and an apparatus for processing repeated access of a terminal device.
Background
With the development of communication technology, 5G communication technology is beginning to be applied in three scenes, namely, mobile bandwidth enhancement, large-scale internet of things and high-reliability low-delay transmission, so that higher requirements on reasonable allocation of resources and processing efficiency are provided.
In the prior art, after a 5G base station (gnnodeb, gNB) receives a radio resource establishment request (RRCSetupRequest) sent by a User Equipment (User Equipment, UE), the gNB allocates radio resources to the UE and sends a radio resource establishment (rrcsetupmessage) message to the UE, and at the same time, starts a wait Timer (Timer) to wait for timing. Further, if the gbb receives a radio resource setup complete (RRCSetupComplete) message sent by the UE and the Timer has not timed out, the gbb determines that the connection of allocating radio resources is complete; if the gNB does not receive the RRCSetupcomplete message sent by the UE all the time, the gNB recovers the resources allocated to the UE after the Timer waits for timeout.
However, after the gbb allocates the radio resources to the UE and before waiting for the Timer not to time out, because the gcb does not receive the RRCSetupComplete message sent by the UE, the gbb allocates the resources to the UE although the gmb has already allocated the resources, but the connection is not successful, at this time, if the gbb receives the RRCSetup message retransmitted by the UE again, the gmb reallocates the radio resources to the UE, and repeats the radio resource allocation process until waiting for the Timer connection to time out and recover the resources, so that the UE occupies the resources allocated by the gbb within a certain time, and cannot timely recover the resources, which causes waste of occupation of the resources and affects the capacity of the system.

Detailed Description
In order to solve the problem that resources cannot be timely recovered in the prior art, the method includes the steps of firstly receiving an RRC connection establishment request message sent by a terminal device, wherein the RRC connection establishment request message carries identity identification information of the terminal device, recovering the last allocated resources when the terminal device is determined to be allocated with the resources based on the identity identification information, adding 1 to failure times of the terminal device for executing RRC connection establishment to obtain current recorded failure times, and re-allocating corresponding resources to the terminal device when the current recorded failure times are determined not to reach a preset failure times threshold value.
The preferred embodiments of the present application will be further described with reference to the accompanying drawings in which:
referring to fig. 1, a process flow of repeated access to a terminal device in the present application is described:
step 101: receiving an RRC connection establishment request message sent by a terminal device, wherein the RRC connection establishment request message carries identity identification information of the terminal device.
After receiving an RRC connection establishment request message (denoted as an RRCSetupRequest) sent by a terminal device, a gNB obtains Identity information of the terminal device, which is carried in the RRC connection establishment request message, in the present application, the Identity information (denoted as an Initial UE-Identity) of the terminal device, where the Initial UE-Identity is configured based on a communication protocol between the gNB and the terminal device, and the content of the Initial UE-Identity may be a random Value or a 5G temporary Identity: 5G-S-TMSI-PART1, wherein, for any terminal device, in the RRC connection establishment request sent by the any terminal device to the gNB each time, the content of the Initial UE-Identity corresponding to the any terminal device is fixed.
Step 102: is the identification information recorded in the terminal device blacklist determined? If yes, go to step 114, otherwise, go to step 103.
Specifically, after acquiring the Initial UE-Identity of the terminal device, the gNB acquires a terminal device blacklist, where the Initial UE-Identity of the terminal device whose RRC connection establishment message reception failure number exceeds the product of a failure number threshold (denoted as accwaittree) and a preset threshold (denoted as accblackthree) is stored in the terminal device blacklist. The failure time threshold is used for limiting the times of failure of receiving RRC connection establishment messages of the terminal equipment, and the gNB executes corresponding operations on the terminal equipment reaching the failure time threshold; the preset threshold is used to represent that the number of failures recorded in the previous comparison process exceeds the upper limit of the number of the failure threshold, the gNB performs corresponding operations on the terminal device exceeding the preset threshold, and specific operation contents will be described in detail later and will not be described again.
Further, if the gNB determines that the Identity information is not recorded in a terminal device blacklist (black ue-Identity) based on the Identity information, the content in step 103 is further determined.
If the gNB determines that the id information is recorded in the terminal device blacklist based on the id information, the content in step 114 is directly executed.
Optionally, if the gNB determines that the terminal device currently initiating the RRC connection access request is a trusted terminal device, such as a terminal device for testing, step 102 may not be performed.
Step 103: and determining whether resources have been allocated to the terminal equipment or not based on the identity identification information, if so, executing step 107, otherwise, executing step 104.
Specifically, the gNB obtains a first terminal device list (denoted as pre-UE-Identity), where the first terminal device list records Identity information of each terminal device to which a resource has been allocated, and further determines, based on the Initial UE-Identity of the terminal device, whether the Initial UE-Identity is recorded in the first terminal device list.
If the gNB determines that the Initial UE-Identity of the terminal device is recorded in the terminal device list, it determines that the terminal device has been allocated with resources, and performs step 107.
If the gNB determines that the Initial UE-Identity of the terminal device is not recorded in the terminal device list, it determines that the terminal device has not been allocated resources, and simultaneously performs step 104.
Step 104: and recording the identity identification information of the terminal equipment in a first terminal equipment list.
Specifically, when the gbb determines that the terminal device is not allocated with resources based on the Initial UE-Identity of the terminal device and a first terminal device list, the gbb records Identity information of the terminal device in the first terminal device list, and records Identity information of each terminal device to which resources have been allocated in the first terminal device list, thereby performing subsequent steps to allocate resources to the terminal device.
Step 105: and allocating resources for the terminal equipment and sending RRC connection establishment information and a preset waiting duration basic value to the terminal equipment.
And after determining that the terminal equipment is not allocated with resources, and recording the identity identification information of the terminal equipment in a first terminal equipment list, the gNB starts to allocate resources to the terminal equipment, wherein the resources comprise channel resources, air interface resources, memory resources and the like which are configured for the terminal equipment by the gNB. Specifically, an RRC connection setup message is sent to the terminal device, and a preset waiting duration base value is executed, where the waiting duration base value (denoted as AccWaitCmpTimer) is configured by the gNB based on actual needs, and is used to represent a waiting duration for the gNB to wait for the terminal device to send the RRC connection setup complete message.
Step 106: an RRC connection setup situation is determined.
Specifically, after the gNB sends an RRC connection setup message and a preset waiting duration basic value to the terminal device, further, if the gNB receives an RRC connection setup complete message sent by the terminal device within the AccWaitCmpTimer waiting duration timing range, it determines that the terminal device successfully executes RRC connection setup; if the gNB does not receive the RRC connection establishment completion message sent by the terminal equipment within the AccWaitCmptimer waiting time duration timing range, the gNB judges that the terminal equipment cannot use the allocated resources in time, and directly recovers the resources allocated to the terminal equipment in order to ensure the timely utilization of the resources.
For example, the gNB sends RRC connection setup messages to a terminal device a and a terminal device B, and executes a preset AccWaitCmpTimer, where the AccWaitCmpTimer is 4s, and if the information received or sent by the terminal device a is not obtained by the gNB within 4s after the gNB sends the RRC connection setup messages, it is determined that the terminal device a cannot use the allocated resources in time, and the gNB directly recovers the resources allocated to the terminal device a; and within 4s after the gNB sends the RRC connection establishment message, the gNB obtains the RRC connection establishment completion message sent by the terminal equipment B based on the message received or sent by the terminal equipment B, and then judges that the terminal equipment B uses the allocated resources in time, and under the condition of normal use, the connection of the terminal equipment B cannot be interfered.
Step 107: and recovering the last distributed resources to obtain the failure times of the current record.
Specifically, after the gbb allocates resources to the terminal device, the gbb determines that the terminal device has allocated resources based on an Initial UE-Identity of the terminal device and a first terminal device list in a process of waiting for the terminal device to send an RRC connection setup complete message, that is, a preset waiting duration basic value is not timed yet, and the gbb recovers the resources allocated to the terminal device last time, determines that the RRC connection setup message reception last time has failed, and obtains a currently recorded failure number (acckeeping) for further determination and execution.
Step 108: and acquiring the total number of the recorded failure times exceeding the failure time threshold in the comparison process of the past times.
Specifically, the gNB obtains, based on the history record, a total number (denoted as AccBlackN) that the number of recorded failures exceeds the threshold of the number of failures in the past comparison process, where the total number is used to represent that the number of recorded failures reaches the total number of the threshold of the number of failures, and adds 1 to the total number and resets the number of currently recorded failures to restart counting each time it is determined that the number of recorded failures reaches the threshold of the number of failures.
For example, the gNB determines, based on the history, that the total number of the recorded failure times of the terminal device C exceeds the failure time threshold is 2 in the history comparison process, where the total number 2 represents that the number of times that the failure times of the terminal device C reaches the failure time threshold is 2 in the history comparison process, that is, if the failure time threshold is 5, then the failure times of two current recordings have reached 5 times, and then the failure times are cleared to 0 and counted again.
For another example, the gNB determines that the number of failures of the current record is 5 based on the history record, the threshold of the number of failures is 5, and since the number of failures of the current record is 5 and reaches the threshold of the number of failures 5, the gNB counts the number of failures that have been recorded by the gNB, clears 0 and recounts the number of failures, and adds 1 to the total number exceeding the threshold of the number of failures.
Optionally, in order to shorten the repeated access processing flow, a larger threshold of failure times may be set, and step 108 may not be executed.
Step 109: and judging whether the total number reaches a preset threshold value, if so, executing the step 113, otherwise, executing the step 110.
And after acquiring the total number of the recorded failure times exceeding the failure time threshold in the comparison process of the past times based on the history record, the gNB compares the total number with a preset threshold value, wherein the preset threshold value is used for representing the upper limit of the number of the recorded failure times exceeding the failure time threshold in the comparison process of the past times. Based on the preset threshold and the threshold of the failure times, interference of normal reasons such as networks and environments can be eliminated, so that when the total number exceeds the preset threshold, step 113 is executed to perform processing, and when the total number does not exceed the preset threshold, step 110 is executed to perform further judgment.
For example, the gNB obtains, based on the history record, that the total number recorded for the terminal device E is 3 times, the preset threshold value is 3, and the failure time threshold value is 5, it is known that the number of times that the failure time of the terminal device E exceeds the failure time threshold value is 3 times, and it is seen that the number of times that the terminal device E accumulates the RRC connection establishment failure has reached at least 15 times, which may be enough to eliminate the interference of the normal cause, so that the terminal device E may be listed as an illegal terminal device, and then step 113 is executed.
Step 110: determine whether the currently recorded failure number reaches a preset failure number threshold? If yes, go to step 111, otherwise go to step 105.
Specifically, the gNB performs determination based on the obtained failure times of the current record and a preset failure time threshold, first obtains a total number of recorded failure times exceeding the failure time threshold based on a history record, further compares the failure times of the current record with the failure time threshold when determining that the total number does not reach the preset threshold, determines that the failure times does not reach the failure time threshold when determining that the failure times of the current record is not greater than the failure time threshold, and performs step 105, otherwise performs step 111.
Therefore, the processing workload of the gNB can be reduced, the judgment process is shortened, and when the total number is judged to reach the preset threshold value, the gNB can determine that the terminal equipment corresponding to the total number is illegal terminal equipment, directly execute the operation of the step 113 on the terminal equipment, and does not judge the relationship between the currently recorded failure times and the failure time threshold value any more. Only when the total number does not reach the preset threshold value, the relationship between the currently recorded failure times and the failure time threshold value needs to be further determined due to the influence of normal reasons such as network and environment.
Step 111: and adding 1 to the total number, clearing the recorded failure times and restarting the calculation.
And when judging that the failure times of the currently recorded terminal equipment reach a preset failure time threshold value, the gNB adds 1 to the total number, wherein the total number is used for representing that the recorded failure times reach the total number of the failure time threshold value, and when determining that the recorded failure times reach the failure time threshold value once, the gNB adds 1 to the total number, clears the recorded failure times and starts counting again.
For example, assuming that the number of failures of the current record of the terminal device F obtained by the gNB is 5, the threshold of the number of failures is 5, and the total number is 1, the gNB clears the number of failures of the current record and restarts counting based on the above determination basis, that is, the number of failures of the current record of the terminal device F after processing is 1, and the total number is 2.
Step 112: setting corresponding waiting time according to the total number of the failure times exceeding the threshold value; and adopting a message of refusing RRC connection establishment to inform the set waiting time length to the terminal equipment.
And when determining that the total number does not reach the preset threshold value but the currently recorded failure times reach the failure time threshold value, the gNB sets corresponding waiting time according to the total number exceeding the failure time threshold value, wherein the waiting time is determined based on the total number, a waiting time accumulation base number and the terminal equipment waiting time, the terminal equipment waiting time (marked as AccWaitTime) is used for representing the waiting time of the next request initiated by the preset terminal equipment, and the waiting time accumulation base number (marked as DeltaAccWaitTime) is used for representing the waiting time accumulation number after the RRC connection establishment message receiving failure times exceed the threshold value. The waiting duration is specifically AccWaitTime + DeltaAccWaitTime × the total number.
Further, the set waiting duration is notified to the terminal device by using a reject RRC connection setup message, that is, the reject RRC connection setup message is sent to the terminal device, where the reject RRC connection setup message carries the waiting duration. And step 113: and writing the identity identification information of the terminal equipment into a terminal equipment blacklist.
And the gNB obtains the total number of the recorded failure times exceeding the threshold value of the failure times based on the history record, and when the total number is determined to reach the preset threshold value, the reason that the RRC connection establishment message of the terminal equipment corresponding to the total number fails to be received is judged to be not the normal reason of the network or the environment, and the terminal equipment corresponding to the total number can be judged to be illegal terminal equipment. Writing the Initial UE-Identity of the terminal equipment into a blacklist of the terminal equipment. The gNB will not allocate resources to the terminal devices recorded in the terminal device blacklist any more.
Step 114: and setting the waiting time length as a maximum value, and notifying the maximum value to the terminal equipment by adopting an RRC connection establishment rejection message.
Specifically, after the gNB performs a series of judgments, after writing the identification information of the terminal device in a terminal device blacklist, or the gNB judges that the identification information is recorded in the terminal device blacklist based on the identification information of the terminal device, further, sends an RRC connection establishment rejection message to the terminal device, sets a waiting duration to a maximum value according to a protocol specification, and notifies the maximum value to the terminal device by using the RRC connection establishment rejection message.
Moreover, for the terminal devices recorded in the terminal device blacklist, the gNB does not allocate resources to the terminal devices.
