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 an auxiliary base station.
Background
In a Non-independent Networking (NSA) scenario, 5G network connection needs to be achieved through 4G network assistance, that is, a terminal needs to access two base stations simultaneously, one is a base station (eNB) of long term evolution (Long Time Evolution, LTE), the other is a base station (gNB) of New Radio, NR), and the 5G side bears data transmission of a part of terminals, so that the service rate of the terminal is greatly improved. The mode in which the terminal accesses two base stations simultaneously may also be referred to as a dual connectivity (EUTRA-NR Dual Connection, EN-DC) mode, in which the LTE base station is a Master base station (MN) and the 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, if the terminal does not receive uplink and downlink data for a long time or cannot receive uplink and downlink data due to abnormal links, the base station still maintains the AS context, the software and hardware resources of the base station are consumed, and when the number of users reaches a certain number, the admission of new users and the normal communication of other active users in the system are affected. For example, when the terminal link is in a normal state, the scenario that no data is transmitted or received in the uplink or downlink is as follows: the user clicks a webpage and then reads the webpage for too long, or the user does not continue clicking other webpages or initiating other services for various reasons under the condition of keeping connection after clicking a webpage; in addition, the possible scenarios that the terminal link is in an abnormal state and normal data transmission and reception cannot be performed are as follows: the terminal enters a shadow area or the terminal fails, such as a sudden power failure of a machine owner, battery removal and other software and hardware failures.
For users in the current NSA networking mode, a terminal (UE) context exists at both the SN and the MN side, and if the MN side cannot timely sense the SN side rate condition, the link and the current state of the terminal, the MN side may also affect the admission of new users to the MN and normal communications of other active users. For example, when the dual-connection user in NSA mode has no uplink and downlink data transmission and reception for a long time, the SN side has abnormal SN side, and cannot perform uplink and downlink data transmission and reception, or the SN side user has abnormal or lost, the SN side cannot notify the MN side of the sensing in real time, 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, possibly affecting the normal communication of the new access user at the MN side, thereby affecting the system performance and user sensing.

Detailed Description
For the purpose of making the objects, technical solutions and advantages of the embodiments of the present application more apparent, the technical solutions of the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present application, and it is apparent that the described embodiments are some embodiments of the present application, but not all embodiments of the present application. All other embodiments, which can be made by those skilled in the art based on the embodiments of the application without making any inventive effort, are intended to be within the scope of the application.
As shown in fig. 1, a flowchart of steps of a network connection control method applied to an MN in an 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 at the same time; 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 obtains a Radio Resource Control (RRC) state of the terminal on the MN side, the MN may receive the terminal state report of the L2 through the RRC, and if the terminal is in the 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 the Radio Resource Management (RRM) to store the RRC state of the terminal on the MN side.
In addition, when the MN obtains the terminal link status of the terminal on the SN side, the MN may receive a user status report sent by the SN, where the user status report includes the terminal link status of the terminal on the SN side.
Of course, the SN may send a secondary base station activity notification (SGNB ACTIVITY NOTIFICATION) message to the MN over the X2 interface to send a user status report to the MN when it detects that the terminal is in idle state and when the SN side link is abnormal.
Step 102: and performing release processing on the terminal or the SN according to the RRC state and the terminal link state.
In this step, specifically, after acquiring the RRC state of the terminal at the MN side and the terminal link state at the SN side, the MN may perform release processing on the terminal or SN according to the RRC state and the terminal link state.
The method and the device can execute release processing on the terminal or the SN when the SN side terminal information is abnormal or lost, or the transmission rate is low due to link abnormality, or abnormal conditions such as data receiving and transmitting exist for a long time, so that the problem that SN side terminal resources cannot be released in time after being maintained in an NR base station for a long time is avoided, the consumption of base station resources is reduced, and the system performance is improved.
Further, in this embodiment, optionally, when the MN performs release processing on the terminal or SN according to the RRC state and the terminal link state, any one of the following may be included:
first, when the terminal link state is a no data transmission state and the RRC state is an inactive state, release processing is performed on the terminal.
Specifically, when the terminal link state of the terminal at the SN side is a data transmission state, that is, there is no data transmission and reception, the MN may query the RRM for the RRC state of the terminal at the MN side, and determine whether the RRC state at the MN side is an inactive state. At this time, when the RRC state is in an inactive state, the terminal release process may be performed, so that the terminal does not have data transmission on the SN side and when the MN side is in an inactive state, resources occupied by the terminal on the MN and SN sides may be released, and base station resource consumption may be reduced, so that the problem that the SN cannot timely release a context of the inactive terminal, and additionally consume resources of a storage context in this case is avoided, and normal communication of a new access terminal on the MN side may not be affected.
And secondly, when the terminal link state is a no data transmission state and the RRC state is not an inactive state, performing release processing on the SN.
Specifically, when the link state of the terminal at the SN side is a data transmission state and the RRC state at the MN side is not an inactive state, the release process may be performed on the SN, that is, the SN is no longer used as a dual-connection secondary base station, so that the resource occupation of the SN is avoided.
Thirdly, when the terminal link state is a low rate transmission state, the RRC state is set to an active state, and release processing is performed on the SN.
Specifically, when the terminal 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, so as to avoid resource occupation on the SN.
Fourth, when the terminal link state is a terminal information loss state and the RRC state is an inactive state, release processing is performed on the terminal.
Specifically, when the link state of the terminal at the SN is the terminal information loss state, the RRM may query the RRC state of the terminal at the MN side, and determine whether the RRC state of the terminal at the MN side is inactive.
At this time, when the RRC state is in an inactive state, the terminal release process may be performed, so that resources occupied by the terminal on the MN and SN sides may be released, and base station resource consumption may be reduced, so that the problem that the SN cannot timely release the context of the inactive terminal in this case, and additionally consume resources for storing the context, and normal communication of the new access terminal on the MN side may not be affected.
Fifthly, when the terminal link state is the terminal information loss state and the RRC state is not the inactive state, performing a release process on the SN.
Specifically, when the link state of the terminal at the SN side is a terminal information loss state and the RRC state at the MN side is not an inactive state, release processing may be performed on the SN, so that resource occupation of the SN is avoided.
In this way, by executing the release processing on the terminal or the SN by any one of the above items, the problem that the SN side terminal resource cannot be released in time after long-term maintenance at the NR base station when the SN side terminal information is abnormal or lost, or the speed is low due to link abnormality, or abnormal conditions such as data receiving and transmitting exist for a long time is avoided, and the base station resource consumption is reduced.
In addition, in this embodiment, optionally, after the SN is released, whether the total number of SN releases reaches the preset number of times threshold before the preset detection timer expires may be detected, and when the total number of SN releases reaches the preset number of times threshold before the detection timer expires, a preset penalty timer is started, and adding to the primary and secondary cells of the SN is prohibited again before the penalty timer expires.
Specifically, after the release processing is performed on the SN, a preset detection timer may be started, and the MN may initiate the adding and releasing processes of the primary and secondary cells of the SN again before the detection timer expires, that is, the base station is used as the secondary base station again and releases the SN, and at this time, the total number of SN releases before the detection timer expires may be recorded.
Of course, when the total number of SN releases reaches the preset number of times threshold, a preset penalty timer may be started, and adding the primary and secondary cells of the SN again is prohibited before the penalty timer times out, that is, the base station corresponding to the primary and secondary cells is prohibited to be used as the secondary base station again. This makes the dual connectivity system more stable over time, reducing the ping-pong effect between base stations.
In addition, specifically, before detecting whether the total number of SN releases reaches a preset number of times threshold before the preset detection timer times out, whether the primary and secondary cells of the SN exist in a preset penalty list can be detected; when the primary and secondary cells are detected to exist in the punishment list, recording the total release times of the SN; when the primary and secondary cells are detected not to exist in the punishment list, adding the primary and secondary cells into the punishment list, and recording the total release times of the SN.
If the total number of SN releases does not reach the preset number of times 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 MN can learn the state of SN, thereby make can avoid the interpolation to the basic station that the service quality is bad, make the dual connectivity system more stable in certain time, reduced the ping-pong effect between the basic station.
In this way, the network connection control method provided by the application, the MN obtains the RRC state of the terminal at the MN side and obtains the terminal link state of the terminal at the SN side, wherein the terminal link state comprises a data transmission state, a low-rate transmission state or a terminal information loss state, and performs release processing on the terminal or the SN according to the RRC state and the terminal link state, thereby avoiding the problem that the terminal resource at the SN side cannot be released in time after being maintained at the NR base station for a long time, reducing the resource consumption of the base station, improving the system performance, enhancing the information interaction and the information synchronization between the LTE base station and the NR base station, and leading the NSA networking to be more flexible.
In addition, as shown in fig. 2, a flowchart of steps of a network connection control method applied to SN in an 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 link on the SN side is abnormal, sending the link state of the terminal on the SN side to the MN.
Specifically, the terminal establishes dual connectivity communication with both the MN and the SN.
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 the L2 through RRC, and if the terminal link state is no data transmission state, low rate transmission state, or a terminal information loss state, and the terminal establishes dual connectivity with the MN and the SN at the same time, then detect whether the terminal is in a process, i.e. is in an idle state, if the terminal is not in an idle state, then the terminal link state is not required to be sent to the MN, and if the terminal is in an idle state, then 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, a user status report may be sent 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 on the SN side to the MN, so that the MN can execute release processing on the terminal or the SN by combining the RRC state of the terminal on the MN side and the terminal link state, thereby avoiding the problem that the terminal resource on the SN side cannot be released in time after being maintained on an NR base station for a long time, reducing the consumption of the base station resource and improving the system performance.
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 also be started, and when the SN release waiting timer is detected to timeout for the first time, the terminal link state is sent to the MN again; and when the SN release waiting timer is detected to timeout for the second time and the SN release request sent by the MN is not received, carrying out release processing on the terminal at the SN side.
That is, after the SN starts the SN release waiting timer, it can determine whether the SN is overtime for the first time, if so, it can 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 wait timer times out for the second time and the SN release request initiated by the MN is not received yet, the SN may automatically release the SN-side terminal, so that when the SN-side terminal information is abnormal or lost, or the transmission rate is low due to link abnormality, or there is no abnormal situation such as data transceiving for a long time, the SN-side terminal can be released, thereby avoiding the problem that the SN-side caused by failing to notify the MN-side perception in real time cannot timely release the context of the link abnormality terminal, avoiding the additional consumption of resources for storing the context, and not affecting the normal communication of the MN-side new access terminal, and improving the system performance and user perception.
An embodiment of the present application will be specifically described with reference to fig. 3.
Referring to fig. 3, the overall flow of the embodiment of the present application is as follows:
the present embodiment includes the following procedure on the SN side:
firstly, acquiring a 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 if the terminal is an NSA user terminal, namely, the MN and the SN are connected at the same time, whether the terminal is in a process, namely, in an idle state can be checked; if not in idle state, not sending user state report to MN; if the mobile terminal is in an idle state, a user state report is sent to the MN through an X2 interface, and the user state report comprises a terminal link state of the terminal at an SN side.
Specifically, the user status report may be transmitted to the MN through a SGNB ACTIVITY NOTIFICATION message.
Then, the SN starts an SN release waiting timer, judges whether the SN release waiting timer is overtime for the first time or not when the SN release waiting timer is overtime, and when the SN release waiting timer is detected to be overtime for the first time, the SN release waiting timer is restarted after the SN release waiting timer is sent to the MN again; when the SN release waiting timer is detected to timeout for the second time and the SN release request sent by the MN is not received, 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 at the MN side through the RRC, and if the terminal is connected with the MN and the SN at the same time, the RRM is informed to store the RRC state of the MN side; and the MN receives a user state report sent by the SN through the X2 interface, so as to acquire the terminal link state of the terminal at the SN side;
then, the MN performs a distinguishing process on different terminal link states reported by the SN side, specifically:
when the link state of the terminal is a non-data transmission state, judging whether the RRC state of the MN side is in 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, notifying the RRM to set the RRC state of the terminal at the MN side as an active state, 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, if so, executing a terminal release processing process, and otherwise, initiating an SN release process.
Then, when MN initiates SN release, a penalty mechanism may be entered, which comprises the steps of:
firstly traversing a preset punishment list, and judging whether a primary cell and a secondary cell of the SN exist in the punishment list or not; if yes, recording the total release times of the SN; if the primary cell and the secondary cell of the SN do not exist, the primary cell and the secondary cell of the SN are added into the punishment list, and the total release times of the SN are recorded, namely the total release times of the SN are set to be 1. Specifically, SN and identification information of a primary and secondary cell (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, 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, and the total SN release times are recorded.
Finally, if the total release times of the SN reach a preset time threshold, stopping the detection timer, starting a preset punishment timer, and prohibiting the addition of 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 between base stations is reduced.
Thus, the network release process of the MN and the SN side is realized through the process, and the resource consumption of the base station is reduced.
