Description
Technical Field
The present application relates to the field of communications technologies, and in particular, to a network connection control method and apparatus, a primary base station, and a secondary base station.
Background
In a Non-independent Networking (NSA) scenario, a 5G network connection needs to be realized by assistance of a 4G network, that is, a terminal needs to access two base stations at the same Time, one is a base station (eNB) of Long Time Evolution (LTE), and the other is a base station (gNB) of New Radio (NR), and a 5G side undertakes data transmission of a part of terminals, thereby greatly improving a service rate of the terminal. A mode in which a terminal simultaneously accesses two base stations may also be referred to as an EUTRA-NR Dual Connection (EN-DC) mode, where an LTE base station is a Master Node (MN), and an NR base station is a Secondary base Station (SN).
In addition, once the terminal initiates access in the base station, the base station stores the context information (AS context) of the access layer of the terminal, and if the terminal has no uplink and downlink data transceiving for a long time or cannot perform uplink and downlink data transceiving due to link abnormality, but the base station still maintains the AS context, the software and hardware resources of the base station are consumed, and when the number of the users reaches a certain number, the admission of new users and the normal communication of other activated users in the system are influenced. For example, when the terminal link is in a normal state, the scenario that both uplink and downlink have no possibility of data transmission and reception is as follows: the reading time is too long after the user clicks a webpage, or the user does not continue to click other webpages or initiate other services for various reasons under the condition of keeping connection after clicking a webpage; in addition, the possible scenarios that the terminal link cannot normally transmit and receive data in the abnormal state are as follows: the terminal enters a shadow area or the terminal malfunctions, such as sudden power off of the owner, battery removal, and other software and hardware malfunctions.
For a user in the current NSA networking mode, a terminal (UE) context may exist on both the SN side and the MN side, and if the MN side cannot timely sense the speed condition of the SN side, the link, and the current state of the terminal, the admission of a new MN user and normal communication of other active users may also be affected. For example, in the NSA mode, under the circumstances that the SN side has no uplink and downlink data transceiving for a long time, the SN side link is abnormal and cannot perform uplink and downlink data transceiving, or the SN side user is abnormal or lost, the SN side cannot notify the MN side in real time of sensing, which results in that the SN side cannot timely release the context of the inactive user, thereby causing additional consumption of resources for storing the context, and at the same time, may affect the normal communication of a newly accessed user at the MN side, thereby affecting the system performance and the user sensing.

Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are some embodiments of the present application, but not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.
As shown in fig. 1, a flowchart of steps of a network connection control method applied to an MN in the embodiment of the present application is shown, where the method includes the following steps:
step 101: and acquiring the RRC state of the terminal at the MN side and acquiring the terminal link state of the terminal at the SN side.
Specifically, the MN may be an LTE base station, and the SN is an NR base station.
In addition, the terminal establishes dual-connection communication with the MN and the SN simultaneously; the RRC state may be an idle state, an inactive state, or a connected state; the terminal link state may include a no data transmission state, a low rate transmission state, or a terminal information loss state.
In addition, specifically, when the MN acquires a Radio Resource Control (RRC) state of the terminal on the MN side, the MN may receive the terminal state report of L2 through the RRC, and at this time, if the terminal is in a dual connectivity mode, that is, the terminal establishes dual connectivity communication with the MN and the SN at the same time, the MN may notify a Radio Resource Management (RRM) to store the RRC state of the terminal on the MN side.
In addition, when acquiring the terminal link state of the terminal at the SN side, the MN may receive a user status report sent by the SN, where the user status report includes the terminal link state of the terminal at the SN side.
Of course, the SN may send an auxiliary base station ACTIVITY NOTIFICATION (SGNB ACTIVITY NOTIFICATION) message to the MN through the X2 interface to send the user status report to the MN when detecting that the terminal is in an idle state and an SN side link is abnormal.
Step 102: according to the RRC state and the terminal link state, release processing is performed for the terminal or the SN.
In this step, specifically, after acquiring the RRC state of the terminal on the MN side and the terminal link state on the SN side, the MN may perform release processing on the terminal or the SN according to the RRC state and the terminal link state.
The method can release the terminal or the SN when the SN side terminal information is abnormal or lost, or the transmission rate is low due to abnormal link, or abnormal conditions such as data receiving and sending do not exist for a long time, thereby avoiding the problem that the SN side terminal resources can not be released in time in the NR base station for a long time, reducing the resource consumption of the base station and improving the system performance.
Furthermore, in this embodiment, optionally, when the MN performs the release processing on the terminal or the SN according to the RRC state and the terminal link state, any one of the following items may be included:
first, when the link state of the terminal is the no data transmission state and the RRC state is the inactive state, the release process is performed for the terminal.
Specifically, when the terminal link state of the terminal on the SN side is a no-data transmission state, that is, no data transmission and reception, the MN may query the RRM about the RRC state of the terminal on the MN side, and determine whether the RRC state on the MN side is an inactive state. At this time, when the RRC state is an inactive state, the terminal release process may be executed, so that the terminal may release resources occupied by the terminal on the MN and the SN side when there is no data transmission on the SN side and the MN side is in an inactive state, and resource consumption of the base station is reduced, thereby avoiding a problem that the SN cannot release a context of the inactive terminal in time under such a situation, and additionally consumes resources for storing the context, and making normal communication of a new access terminal on the MN side not affected.
And secondly, when the link state of the terminal is a no-data transmission state and the RRC state is not an inactive state, releasing the SN.
Specifically, when the link state of the terminal on the SN side is a no-data transmission state and the RRC state on the MN side is not an inactive state, the terminal may perform release processing on the SN, that is, the SN is no longer used as a secondary base station for dual connectivity, thereby avoiding resource occupation of the SN.
And thirdly, when the link state of the terminal is a low-rate transmission state, setting the RRC state to be an activated state, and performing release processing on the SN.
Specifically, when the link state of the terminal at the SN side is a low-rate transmission state, that is, the rate is low due to link abnormality, the MN may notify the RRM to set the RRC state at the MN side to an active state, and initiate SN release, that is, perform release processing on the SN, thereby avoiding resource occupation on the SN.
And fourthly, when the link state of the terminal is the terminal information loss state and the RRC state is the non-activated state, releasing the terminal.
Specifically, when the link state of the terminal at the SN is the terminal information loss state, the RRC state of the terminal at the MN side may be queried for the RRM, and whether the RRC state of the terminal at the MN side is an inactive state is determined.
At this time, when the RRC state is an inactive state, the terminal release process may be performed, so that resources occupied by the terminal on the MN and the SN side may be released, and resource consumption of the base station may be reduced, thereby avoiding a problem that the SN cannot release the context of the inactive terminal in time and additionally consumes resources for storing the context, and preventing normal communication of the new access terminal on the MN side from being affected.
And fifthly, when the terminal link state is the terminal information loss state and the RRC state is not the non-activated state, releasing the SN.
Specifically, when the link state of the terminal on the SN side is the terminal information loss state and the RRC state on the MN side is not the inactive state, the release process may be performed on the SN, thereby avoiding resource occupation of the SN.
Therefore, by executing the release processing on the terminal or the SN according to any item, the problem that the SN side terminal resource can not be released in time after long-term maintenance on the NR base station when the SN side terminal information is abnormal or lost, or the SN side terminal information is low in rate due to abnormal link, or no data receiving and sending and other abnormal conditions exist for a long time is avoided, and the resource consumption of the base station is reduced.
In addition, in this embodiment, optionally, after the release processing is performed on the SN, it may be further detected whether the total number of releases of the SN reaches a preset number threshold before the preset detection timer expires, and when it is detected that the total number of releases of the SN reaches the preset number threshold before the detection timer expires, a preset penalty timer is started, and the main and auxiliary cells of the SN are prohibited to be added again before the penalty timer expires.
Specifically, a preset detection timer may be started after releasing the SN, and the MN may initiate the addition and release process of the primary and secondary cells of the SN again before the detection timer expires, that is, the base station may be used as the secondary base station again and released, and at this time, the total number of times of releasing the SN before the detection timer expires may be recorded.
Of course, when the total number of released SNs reaches the preset number threshold, a preset penalty timer may be started, and the addition of the primary and secondary cells of the SN is prohibited again before the penalty timer expires, i.e., the base station corresponding to the primary and secondary cells is prohibited from being used as the secondary base station again. This makes the dual connection system more stable for a certain time, reducing ping-pong effects between base stations.
In addition, specifically, before detecting whether the total number of times of releasing the SN reaches a preset number threshold before a preset detection timer expires, it may also be detected whether the primary and secondary cells of the SN exist in a preset punishment list; when detecting that the main and auxiliary cells exist in the punishment list, recording the total releasing times of the SN; and when detecting that the primary and secondary cells do not exist in the penalty list, adding the primary and secondary cells into the penalty list, and recording the total releasing times of the SN.
It should be noted that, if the total number of times of releasing the SN does not reach the preset number threshold before the detection timer expires, the primary and secondary cells of the SN may be deleted from the penalty list.
Through setting up punishment list for the MN can learn the state of SN, thereby makes and to avoid the addition to the not good basic station of quality of service, makes two connected systems more stable in a certain time, has reduced the ping-pong effect between the basic station.
In the network connection control method provided by the application, the MN acquires the RRC state of the terminal at the MN side and acquires the terminal link state of the terminal at the SN side, wherein the terminal link state comprises a no-data transmission state, a low-rate transmission state or a terminal information loss state, and the release processing is executed on the terminal or the SN according to the RRC state and the terminal link state, so that the problem that the terminal resources at the SN side cannot be released in time in the NR base station for a long time is solved, the resource consumption of the base station is reduced, the system performance is improved, the information interaction and the information synchronization between the LTE base station and the NR base station are enhanced, and the NSA networking is more flexible.
In addition, as shown in fig. 2, a flowchart of steps of a network connection control method applied to the SN in the embodiment of the present application is shown, where the method includes the following steps:
step 201: and when the terminal is detected to be in an idle state and the SN side link is abnormal, sending the terminal link state of the terminal at the SN side to the MN.
Specifically, the terminal establishes dual-connection communication with the MN and the SN at the same time.
In addition, the terminal link state includes a no data transmission state, a low rate transmission state, or a terminal information loss state.
Specifically, the SN may receive the terminal link state reported by L2 through the RRC, and at this time, if the terminal link state is a no-data transmission state, a low-rate transmission state, or a terminal information loss state, and when the terminal establishes dual-connection communication with the MN and the SN at the same time, it detects whether the terminal is in the process, that is, whether the terminal is in an idle state, at this time, if the terminal is not in the idle state, the terminal link state is not sent to the MN, and if the terminal is in the idle state, the terminal link state of the terminal on the SN side may be sent to the MN.
Specifically, when the SN sends the terminal link state of the terminal on the SN side to the MN, the SN may send a user status report to the MN, where the user status report includes the terminal link state of the terminal on the SN side.
The SN sends the terminal link state of the terminal at the SN side to the MN, so that the MN can perform release processing on the terminal or the SN by combining the RRC state of the terminal at the MN side and the terminal link state, the problem that the terminal resource at the SN side can not be released in time after being maintained at an NR base station for a long time is solved, the resource consumption of the base station is reduced, and the system performance is improved.
In addition, in this embodiment, optionally, after the SN sends the terminal link state of the terminal on the SN side to the MN, a preset SN release waiting timer may be started, and when detecting that the SN release waiting timer times out for the first time, the SN may send the terminal link state to the MN again; and when detecting that the SN release waiting timer is overtime for the second time and does not receive the SN release request sent by the MN, releasing the terminal at the SN side.
After starting the SN release waiting timer, the SN may determine whether the SN is overtime for the first time, and if the SN is overtime for the first time, the SN may send a user status report to the MN again through the X2 interface and start the SN release waiting timer again to wait for the processing result of the MN; if the SN release waiting timer is overtime for the second time and still does not receive the SN release request initiated by the MN, the SN can automatically release the terminal at the SN side, so that when the terminal at the SN side is abnormal or lost, or the transmission rate is low due to abnormal link, or no abnormal conditions such as data receiving and sending exist for a long time, the terminal at the SN side can be released, the problem that the SN side cannot timely release the context of the terminal with the abnormal link due to the fact that the MN side cannot be informed in real time is avoided, extra resources for storing the context are avoided being consumed, normal communication of a new access terminal at the MN side cannot be influenced, and system performance and user perception are improved.
The following specifically describes an embodiment of the present application with reference to fig. 3.
Referring to fig. 3, the overall process of the embodiment of the present application is as follows:
the present embodiment includes the following processes on the SN side:
firstly, acquiring the current link state of a terminal through RRC, wherein the link state is a no-data transmission state, a low-rate transmission state or a terminal information loss state, and at the moment, if the terminal is an NSA user terminal, namely, MN and SN are connected simultaneously, whether the terminal is in the process, namely, whether the terminal is in an idle state can be checked; if not, the user state report is not sent to the MN; and if the mobile terminal is in an idle state, sending a user state report to the MN through an X2 interface, wherein the user state report comprises a terminal link state of the terminal at the SN side.
Specifically, the user status report may be sent to the MN through an SGNB active NOTIFICATION message.
Then, the SN starts an SN release waiting timer, judges whether the SN release waiting timer is overtime for the first time when the SN release waiting timer is overtime, and sends the terminal link state to the MN again when the SN release waiting timer is detected to be overtime for the first time and restarts the SN release waiting timer; and when detecting that the SN release waiting timer is overtime for the second time and does not receive the SN release request sent by the MN, the SN automatically releases the SN side terminal.
The present embodiment includes the following procedures on the MN side:
firstly, the MN acquires the RRC state of the terminal on the MN side through the RRC, and if the terminal is connected with the MN and the SN simultaneously, the RRM is informed to store the RRC state of the MN side; in addition, the MN receives a user state report sent by the SN through an X2 interface, so as to obtain the terminal link state of the terminal at the SN side;
then, the MN performs differentiated processing on different terminal link states reported by the SN side, specifically:
when the terminal link state is a no-data transmission state, judging whether the RRC state of the MN side is an inactive state, if so, executing a terminal release processing process, otherwise, initiating an SN release process;
when the link state of the terminal is a low-rate transmission state, informing the RRM to set the RRC state of the terminal at the MN side to be an active state (active) and initiating an SN release process;
and when the link state of the terminal is a terminal information loss state, inquiring the RRC state of the terminal at the MN side from the RRM, judging whether the RRC state at the MN side is an inactive state (inactive), if so, executing a terminal release processing process, otherwise, initiating an SN release process.
Then, when the MN initiates SN release, a penalty mechanism may be entered, which includes the steps of:
firstly, traversing a preset penalty list, and judging whether a main cell and an auxiliary cell of the SN exist in the penalty list or not; if yes, recording the total release times of the SN; and if the SN does not exist, adding the primary and secondary cells of the SN into the penalty list, and recording the total releasing times of the SN, namely setting the total releasing times of the SN to be 1. Specifically, the SN and the identification information of the primary and secondary cells (PSCell) may be added to the penalty list.
And then, starting a preset detection timer, and before the detection timer is overtime, if the MN initiates the SN release of the PSCell again, and certainly, the reason for the SN release is that the terminal link state of the terminal at the SN side is a no-data transmission state, a low-rate transmission state or a terminal information loss state, recording the total release times of the SN.
And finally, if the total release times of the SN reaches a preset time threshold, stopping the detection timer and starting a preset punishment timer, and forbidding adding the PSCell before the punishment timer is overtime, so that the dual-connection system is more stable in a certain time, and the ping-pong effect among the base stations is reduced.
