Description
Technical Field
The present invention relates to the field of communications technologies, and in particular, to a method, a system, and a storage medium for reducing consumption of base station resources by a connected terminal.
Background
In 4G and 5G wireless communication systems, the tasks of the user plane scheduling of the medium access control layer of the base station are: 1) and allocating physical layer resources including physical uplink control channel resources to the terminal in the access process. 2) And selecting a terminal in each scheduling period, and distributing physical layer resources including a physical downlink control channel, a physical downlink shared channel, a physical uplink control channel and a physical uplink shared channel for data transmission according to the data volume to be transmitted of the terminal and the channel condition. 3) And the physical uplink control channel is allocated to the terminal for use according to the time, frequency band and code word triad. The terminal in the connected state occupies the physical uplink control channel resource, and the media access control layer and the physical layer of the base station need to perform corresponding processing on the frequency band at the corresponding moment whether to send a message or not.
With the increase of the permeability of the mobile internet, the terminal uses continuous fragmentation for network resources. For example, after a web page is browsed and refreshed, it may be necessary to read for several seconds or several tens of seconds; a small video is refreshed and needs to be viewed for a few seconds or a dozen seconds after the downloading is completed. In order to cope with such a scenario, radio resource control layers are introduced in 4G and 5G to realize a deactivated state for the terminal. However, when the network side has data to send to the terminal in the deactivated state of the radio resource control layer, the terminal needs to be paged by using a paging mechanism. Because the paging process generally sends paging messages in several to dozens of cells at the same time, more resources are consumed; and each paging cycle is 320 milliseconds at the shortest, and the paging delay is larger. Therefore, the terminal in the connected state generally transitions to the deactivated state of the radio resource control layer after countless tens of seconds, and the technology can only be applied to the scene of interrupting the transmission of tens of seconds.
Short-time data transmission and several-second interruption scenes such as mobile phone application heartbeat packages and shopping browsing software in wireless networks are increasing nowadays. In this scenario, the terminal cannot switch to the radio resource control layer deactivated state if the time for stopping data transmission is too short, and the terminal in the connected state occupies the physical uplink control channel resource, which causes unnecessary load on the media access control layer and the physical layer and affects the access of more terminals in the cell.

Detailed Description
The technical solutions in the embodiments of the present disclosure will be clearly and completely described below with reference to the drawings in the embodiments of the present disclosure, and it is obvious that the described embodiments are only a part of the embodiments of the present disclosure, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments disclosed herein without making any creative effort, shall fall within the protection scope of the present disclosure.
Fig. 1 is a schematic flow chart illustrating a method for reducing consumption of base station resources by a connected terminal according to an embodiment of the disclosure. The method for reducing consumption of base station resources by a connected terminal shown in this embodiment may be applied to communication between a base station and a terminal, where the base station includes, but is not limited to, a 4G base station, a 5G base station, and a 6G base station, the terminal may be used as a user equipment, and the terminal includes, but is not limited to, an electronic device such as a mobile phone, a tablet computer, a wearable device, a sensor, and an internet of things device.
When a certain base station operates in the existing network, the physical uplink control channel resource is insufficient, and the time occupied by the media access control layer in one-time scheduling is almost close to the exhausted transmission interval time. Analyzing and finding that the scheduling time of a media access control layer is very long when the physical uplink control channel message is processed. Techniques have thus been developed to reduce physical uplink channel resources.
Referring to fig. 1, the method for reducing consumption of base station resources by a connected terminal according to the present invention includes the following steps:
step 101: after the terminal completes the random access procedure, the base station starts the countless transmission timers, which are defined in this embodiment, each terminal scheduling entity has one, and the terminal scheduling entities are software entities corresponding to the terminals one to one in the base station and used for storing and maintaining the states of the terminals on the base station.
Step 102: checking whether the countless transmission timers are overtime according to a set time interval, wherein the count values of the countless transmission timers are reduced at a fixed interval after being started, and the countless transmission timers are regarded as overtime when the count values are 0; according to the time length of idle wireless resources of the terminal, the active control terminal is determined to enter the uplink lost gait, so that the utilization rate of the physical uplink control channel is improved, the time consumption of the media access control layer in message processing and scheduling is reduced,
if the countless transmission timer is overtime, the base station stops sending a time synchronization command to the countless transmission timer overtime terminal, and calculates the out-of-step time of the terminal, wherein the out-of-step time of the terminal is the overtime time point of the time synchronization timer obtained by calculation according to the time sent by the latest time synchronization command and the configuration of the time synchronization timer of the terminal;
the time synchronization timer in this embodiment is a timer specified in the protocol of the third generation partnership project. Each terminal maintains a time synchronization timer. When the terminal receives a time synchronization command (TAC) sent by the base station, the timer is reset to an initial value, the timer is reduced by 1 every millisecond, when the value is 0, the timer is considered to be overtime, and after the time is overtime, the uplink connection of the terminal and the cell is considered to be out of step. The method for maintaining the uplink synchronization between the terminal and the cell by the base station is to send a time synchronization command (TAC) to the terminal to reset the timer before the timer expires.
Step 103: waiting for the terminal out-of-step time to arrive, and after the terminal out-of-step time arrives, switching the terminal to an uplink out-of-step state, and releasing the resource corresponding to the terminal by the base station, specifically in one embodiment of the present invention, the base station releases the resource corresponding to the terminal, and the method includes:
clearing all hybrid automatic repeat request buffers;
releasing all configured uplink physical control channel resources;
releasing the configured sounding reference signal resources;
clearing all configured downlink grants and uplink grants;
clearing all physical uplink shared channel resources used for reporting the semi-static channel state information;
and the terminal automatically shifts to the uplink gait loss and releases resources because the time synchronization command is not received in the set time. After the terminal out-of-step time is reached, the network side only needs to transfer the terminal scheduling entity corresponding to the terminal to the uplink out-of-step.
Referring to fig. 2, in addition, in an embodiment of the present invention, the method further includes step 104: after the countless transmission timers are started, if the terminal successfully schedules the data, the data uplink transmission or the data downlink transmission is carried out, and the countless transmission timers are not overtime, the countless transmission timers are reset to initial values, and through the setting, the terminal can be interrupted to enter an uplink missing gait when the terminal reschedules the data.
According to the 3gpp protocol, the terminal has three radio resource control layer states: the wireless resource control layer is in a connection state, a non-activation state and an idle state. When the terminal is in the radio resource control layer connection state, the terminal is divided into an uplink synchronous radio resource control layer connection state and an uplink out-of-step radio resource control layer connection state according to whether time synchronization is completed or not. The uplink desynchronizing state is short for the uplink desynchronizing radio resource control layer connection state, and the uplink synchronizing state is short for the uplink synchronizing radio resource control layer connection state.
In this embodiment, a terminal without data transmission for a period of time is controlled to enter a radio resource control layer connection state with uplink desynchronization, according to a protocol of the third generation partnership project (3gpp), the terminal releases physical uplink control channel resources, and a base station media access control layer also synchronously releases the physical uplink control channel resources of the terminal. Thus, the base station media access control layer does not process the physical uplink control channel message of the terminal.
In the existing base station design, the uplink desynchronization occurs after the uplink desynchronization of the terminal due to the failure of sending a time synchronization command (TAC) and the like, and the base station can immediately send a physical downlink control channel command to the terminal. The terminal initiates random access to realize uplink synchronization after receiving the physical downlink control channel command.
In the invention, after the terminal is controlled to enter the uplink gait loss state, compared with the terminal in the uplink synchronous wireless resource control layer connection state, the time consumed by the physical layer and the media access control layer for processing the physical uplink control channel can be effectively reduced, the time consumed by the media access control layer for scheduling can be effectively reduced, and the requirement of the media access control layer for hardware resources can be reduced;
the terminal is controlled to enter the uplink out-of-step state, and compared with the switching from the radio resource control layer connection state to the non-activated state, the signaling interaction can be faster and less. The terminal is controlled to enter the uplink out-of-step state only by the base station to stop sending the time synchronization command to the terminal, and the wireless resource control layer connection state to the non-activation state needs to send two wireless resource control layer signaling between the terminal and the base station.
In addition, in the invention, the re-synchronization of the terminal with the uplink gait loss is faster relative to the switching from the inactive state to the connected state of the radio resource control layer, and the terminal can be recovered to the connected state of the radio resource control layer with the uplink synchronization more quickly. The method comprises a synchronization process that the terminal has data sending trigger at the terminal side and a synchronization process that the terminal has data sending trigger at the network side.
Specifically, in an embodiment of the present invention, when a terminal is in an uplink failure state, if there is data transmission at a terminal side, the terminal initiates a random access based on collision, the terminal initiates a random access on a preamble resource, a base station sends a random access response message to the terminal after receiving the preamble, the terminal sends a connection establishment request message to the base station after receiving the random access response message, the connection establishment request message includes a cell radio network temporary identifier, the base station receives the cell radio network temporary identifier carried by the random access message, the base station checks a physical uplink control channel resource of a terminal scheduling entity, if no physical uplink control channel resource is allocated, the physical uplink control channel resource is reallocated, and triggers a radio resource control layer to reconfigure, and release the newly allocated cell radio network temporary identifier and a corresponding resource in a random access process, after receiving the reconfiguration message of the radio resource control layer, the terminal reconfigures the physical uplink control channel resources and recovers the connection state of the radio resource control layer from the terminal to uplink synchronization.
Specifically, in an embodiment of the present invention, when there is data to be sent to a terminal in an uplink gait loss, the method may specifically be represented as: in a radio link control layer of a base station, a data buffer area of a corresponding terminal is changed from empty to non-empty; informing a media access control layer of a base station to add the service flow of the corresponding terminal into a scheduling queue;
the base station generates a physical downlink control channel command to trigger uplink synchronous recovery, and after the terminal receives the physical downlink control channel command, the terminal initiates random access on a designated preamble signal resource;
after receiving the appointed leading signal, the base station sends a random access response, the base station checks the physical uplink control channel resource of the terminal scheduling entity, if the physical uplink control channel resource is not allocated, the physical uplink control channel resource is reallocated, the reconfiguration of a wireless resource control layer is triggered, after the terminal receives the reconfiguration message of the wireless resource control layer, the physical uplink control channel resource is reallocated, and the connection state of the terminal to the uplink synchronous wireless resource control layer is recovered.
After the base station generates a physical downlink control channel command to trigger uplink synchronization recovery, if the random access waiting timer is overtime, a new physical downlink control channel command is generated.
In addition, referring to fig. 2, in an embodiment of the present invention, the method further includes step 105: when countless transmission timers corresponding to the terminal are overtime and do not reach the terminal out-of-sync time, data is to be transmitted, and for the situation, data uplink or downlink transmission can be performed, which is represented as: when the countless transmission timers corresponding to the terminal are overtime and do not reach the terminal out-of-step time, if data transmission exists, data transmission is carried out according to the flow of the uplink synchronous radio resource control layer connection state; when the terminal out-of-step time arrives, the data transmission is stopped, the uplink resource is cleared, and the uplink out-of-step state is entered. And the base station at the network side stops data transmission, eliminates the uplink resource corresponding to the terminal and transfers the terminal scheduling entity corresponding to the terminal to an uplink lost gait.
When the terminal has data to send to the base station: by adopting the method of the invention, the terminal with the ascending gait losing needs to initiate random access and needs two signaling of the radio resource control layer; the radio resource control layer inactive state terminal also needs to initiate random access and needs two radio resource control layer signaling.
When the base station on the network side has data to send to the terminal: by adopting the method of the invention, the base station needs to send a physical downlink control channel command to the terminal with the uplink gait losing, and then the terminal initiates random access and needs two signaling of a wireless resource control layer; in the prior art, a base station needs to send paging information to a terminal in a radio resource control layer inactive state, the paging information consumes more time and resources than a physical downlink control channel command, and then the terminal initiates random access and needs two radio resource control layer signaling.
By the method provided by the embodiment, the terminal with the uplink gait loss synchronizes again and can recover to the uplink synchronous radio resource control layer connection state more quickly relative to the switching from the radio resource control layer non-activation state to the connection state.
