Cell selection refers to a process in which a terminal device selects a cell that meets preset conditions and camps on it. The cell selection may occur when the terminal equipment is powered on or reconnects to the network after being disconnected from the network; or, the cell selection may also occur when the terminal equipment enters the connected state from the idle state. The process of cell selection by the terminal device will be described below.

When the terminal device is turned on or re-connected to the network, the NAS layer of the terminal device first selects the PLMN according to the list of available public land mobile networks (PLMN) provided, and tries to register on the selected PLMN. to obtain the service of the operator corresponding to the PLMN.

After selecting a PLMN, the terminal device performs cell selection. The purpose of cell selection is to enable the terminal equipment to select a cell with satisfactory signal quality as soon as possible under the selected PLMN to camp on.

During the cell selection process, the terminal needs to measure the cell to be selected in order to evaluate the signal quality and judge whether it meets the criteria for camping. The measurement standard for cell selection is called the S criterion. When the signal quality of a certain cell satisfies the S criterion, it can be selected as a resident cell. The specific content of the S criterion is as follows.

The S criterion is defined as: Srxlev>0 and Squal>0. Among them, Srxlev represents the cell selection reception level value (also can be understood as the reference signal receiving power (reference signal receiving power, RSRP) of the terminal equipment in the cell), Squal represents the cell selection reception quality value (also can be understood as the terminal equipment in the cell Reference signal receiving quality (reference signal receiving quality, RSRQ) of the cell. If the signal measurement result of the cell satisfies the conditions of Srxlev>0 and Squal>0, it indicates that the cell is suitable for camping. For the convenience of description, Srxlev and Squal are referred to as S parameters below.

The calculation formula of the above-mentioned S parameter can be as follows, for example:

Srxlev＝Qrxlevmeas–(Qrxlevmin+Qrxlevminoffset)–Pcompensation–Qoffsettemp

Squal＝Qqualmeas–(Qqualmin+Qqualminoffset)–Qoffsettemp

Among them, Qrxlevmeas represents the measured value of RSRP of the terminal device in the cell, Qqualmeas represents the measured value of RSRQ of the terminal device in the cell, Qrxlevmin represents the minimum receiving level (also called minimum RSRP) required by the cell, and Qqualmin represents the minimum RSRQ value required by the cell Reception quality (also called minimum RSRQ), Qrxlevminoffset represents the minimum reception level offset of the cell, and Qqualminoffset represents the minimum reception quality offset of the cell. The network device can send Qrxlevmeas, Qqualmeas, Qrxlevmin, Qqualmin, Qrxlevminoffset, Qqualminoffset and other parameters to the terminal device by broadcasting.

Pcompensation is used to punish terminal devices that fail to meet the maximum transmission power requirement of the cell, and the calculation formula of Pcompensation is: Pcompensation=max(pmax-pumax,0)(db). pmax indicates the maximum uplink transmission power of the terminal device allowed by the cell, and pumax indicates the maximum uplink transmission power supported by the capability of the terminal device.

Qoffsettemp is a penalty factor introduced for a cell with multiple T300 timeouts, that is, the terminal device sends RRCSetupRequest on this cell for many times, but does not receive the RRCSetup message. The Qoffsettemp parameter can be specified in SIB1.

The calculation formula of the above S parameter is only for illustration and does not limit the embodiment of the present application. In some embodiments, the calculation formula of the S parameter may also use other formulas, for example, the Qoffsettemp parameter may also be omitted from the calculation formula of the S parameter.

It can be seen from the above description that in the prior art, when a terminal device selects a cell, it usually selects a serving cell based on signal strength and quality.

However, in some application scenarios, such as train stations or stadiums where there are multiple cells and multiple PLMN cross-coverage areas, if there are a large number of users at the same time, these terminal devices will be based on the existing S When cell selection is performed according to the criteria, multiple terminal devices will access the same cell with the strongest signal.

However, due to the limited link resources of the cell for transmitting signals, each terminal device can only be allocated very few resources, which will make the data network service provided by the cell for the terminal device incompatible with the application of the terminal device. Scenarios are matched, resulting in data service congestion of terminal equipment. For example, when a user needs to make a video call, the cell where the user is camped cannot provide enough uplink and downlink resources for the user, which causes problems such as freezing during the video call. For another example, when a game needs to be played, the delay of the current network cannot meet the requirements of the game, which affects the user experience.

This will make the terminal equipment camped in the cell unable to obtain the voice or data service matching the signal strength, that is, the data service congestion of the user terminal will occur. For example, when a video call needs to be made, the downlink rate is reduced because the network device cannot provide enough resources, and the problem of freezing or disconnection occurs.

In related technologies, in mobile phones based on the Android platform, when data service congestion is detected, the data call reconstruction process can be executed at the phone frame layer, and the deactivation and activation process can be triggered, so that the terminal device actively performs cell reselection in order to attempt to connect Enter a cell that can provide sufficient network resources.

In the above method, when the terminal device performs cell reselection, it still performs cell reselection according to the above-mentioned S criterion, and takes the cell with the best current signal strength and signal quality as the target cell. When the location of the terminal device does not change greatly, there is a high probability of re-registering with the same serving cell, so that the terminal device cannot be released from the state of data traffic congestion.

Embodiments of the present application provide a congestion processing method and device, a terminal device, and a readable storage medium. Firstly, the congestion processing method provided by this application will be described in detail below with reference to the accompanying drawings.

Fig. 2 is a schematic flow chart of a congestion processing method provided by an embodiment of the present application. The method is used to perform cell switching when the data service of the terminal equipment is congested, so as to provide the terminal equipment with data network services matching the application scenario.

Wherein, whether the terminal device is in the state of data service congestion may be determined by the terminal device according to its service requirements and the wireless network resources provided by the currently accessed serving cell. For example, in the video call scenario mentioned above, when the uplink and downlink rates of the network provided by the serving cell cannot meet the requirements of the video call, it can be determined that the data service congestion of the current terminal device. For ease of description, the specific method for determining whether the terminal device is in data traffic congestion will not be expanded here, and will be described in detail later.

The method in Fig. 2 includes steps S210-S220. The method is applied to a terminal device, and the terminal device may be, for example, the terminal device shown in FIG. 1 above.

In step S210, when the data service of the terminal equipment is congested, the current serving cell is added to the congestion list.

In this embodiment of the application, if the terminal device is congested with data traffic, it indicates that the cell where it resides (that is, the current serving cell) cannot provide network resources that match the data traffic of the terminal device, and it needs to try to access other cells in an attempt to improve data traffic congestion.

In the process of cell handover, according to the method in the prior art, the terminal device will select a cell with higher signal quality and signal strength to access. However, in the method of the embodiment of the present application, the current serving cell is added to the congestion list; and the congestion list is configured to store one or more cells for terminal device access. In this way, the terminal device will not access the cell again when cell switching is performed.

In some implementation manners, the congestion list stores identification information of the above-mentioned one or more cells prohibited from re-access to uniquely identify a cell, and the identification information may be, for example, a physical cell identifier (Physical Cell Identifier, PCI) of the cell. When data service congestion occurs, the terminal device can determine multiple cells that are prohibited from re-accessing according to multiple PCIs in the congestion list, so as to avoid re-accessing the cells in the list during cell handover.

In some implementations, the congestion list may be stored in a preset storage location of the terminal device, and the terminal device may obtain the congestion list from the preset storage location when congestion occurs and needs to perform cell switching; exemplary, the The congestion list may also be obtained by the terminal device from other devices. For example, the terminal device may obtain the congestion list from a storage server, etc. The embodiment of the present application does not specifically limit the access method of the congestion list.

In step S220, the terminal device switches from the current serving cell to the target cell.

In the above step S210, the current serving cell has been added to the congestion list. Therefore, the target cell is a different cell than the current serving cell. Further, when multiple cells are included in the congestion list, the target cell is different from the cells in the congestion list, so that the terminal device can be prevented from re-accessing a cell where data traffic congestion occurs.

In the embodiment of the present application, when the data traffic of the terminal equipment is congested, the currently serving cell is added to the congestion list, and the terminal equipment is prohibited from accessing the cells in the congestion list, so that the cell with traffic congestion can be avoided during cell handover, so that Terminal devices can break away from congestion, provide data network services that match the application scenarios, and improve user experience.

In some implementation manners, the above congestion handling method further includes: selecting a target cell from multiple neighboring cells of the current serving cell.

Wherein, the plurality of neighboring cells may refer to other cells within the range where the terminal device is currently located. The multiple neighboring cells may be determined based on one or more of the following information: the public land mobile network PLMN supported by the terminal device and the radio access technology RAT supported by the terminal device.

The terminal device in this embodiment of the present application may be a device supporting multiple subscriber identity module (SIM) cards, and in this case, the terminal device may also be called a multi-card terminal device. For such terminal equipment, different SIM cards usually belong to different operator networks, that is, correspond to different PLMNs respectively. Therefore, the multiple adjacent cells mentioned above may be multiple cells in different PLMNs.

The embodiment of the present application does not limit the type, shape, and quantity of SIM cards supported by the terminal device. For example, the SIM card may include, but is not limited to: a standard SIM card (Standard SIM), a mini SIM card (Mini SIM), a micro SIM card (MicroSIM) and an ultra-small SIM card (Nano SIM).

The above-mentioned terminal device may also be a device supporting multiple RATs, wherein the wireless access technology may include but not limited to Long Term Evolution (Long Term Evolution, LTE), LTE evolution system (LTE-Advanced), 5G (New Radio, NR) wait. Therefore, the multiple neighboring cells may include cells of multiple RATs supported by the terminal device, such as LTE cells or NR cells.

In some implementation manners, the aforementioned multiple neighboring cells may include one or more of the following:

A plurality of first cells belonging to the same public land mobile network PLMN and the same radio access technology RAT as the current serving cell; a plurality of second cells belonging to the same PLMN and not belonging to the same RAT as the current serving cell; and the current The serving cell does not belong to multiple third cells of the same PLMN.

Taking the NR cell of the first PLMN as the current serving cell as an example, the above-mentioned multiple first cells are other NR cells of the first PLMN, the multiple second cells may be LTE cells of the first PLMN, and the multiple third cells may be A cell of the second PLMN.

In some implementation manners, the foregoing multiple neighboring cells may also be determined according to a current data service request of the terminal device. For example, when a terminal device is performing services such as file downloads or video calls, it has high requirements for uplink and downlink rates. At this time, neighboring cells can be limited to NR cells, that is, multiple neighboring cells can include the NR cell of the current PLMN and the NR cell. NR cells of other PLMNs supported by the terminal device; or, when the current user needs services such as phone calls or text messages, it is necessary to limit the candidate cells to the current PLMN, that is, multiple neighboring cells only include multiple cells in the current PLMN. The cell of the RAT.

In some implementation manners, the terminal device selecting the target cell from the multiple neighboring cells may be: selecting the target cell from the multiple neighboring cells according to the priority order of the multiple neighboring cells.

Wherein, the priority order of multiple adjacent cells includes at least one of the following: the priority of the first cell is greater than the priority of the second cell; the priority of the second cell is greater than the third cell; the priority of the first cell is greater than that of the second cell; Second district.

As an implementation, when determining the target cell, it can be selected from the first cell that belongs to the same PLMN and the same RAT as the current serving cell; when there is no target cell in the first cell, select the second cell of another RAT. cell; when the target cell does not exist in the second cell, then determine the target cell from multiple third cells.

In some implementation manners, the above-mentioned target cell is a cell whose network transmission capability can meet the data service request of the terminal device.

Based on this, as a possible implementation, when selecting the target cell, the network transmission capability of each neighboring cell at the current moment can be obtained, and the cell whose network transmission capability is greater than the data service request of the terminal device is selected as the target cell . In this implementation manner, the selection of the target cell may be performed sequentially according to the above priority order.

In some embodiments, the above method further includes: determining the data service request of the terminal device and the network transmission capability of the current serving cell; if the network transmission capability of the current serving cell cannot meet the data service request of the terminal device, then determining that the terminal device is currently in Data service congestion status.

In some embodiments, the data service request of the terminal device can be characterized by the data rate of the application program of the current terminal device, and the network transmission capability of the cell can be represented by the network throughput rate of the cell. By determining whether the network throughput rate can meet the requirements of the application The program data rate can determine whether the current terminal device is in a state of data traffic congestion. The process will be described in detail below with reference to FIG. 3 .

FIG. 3 shows a schematic flow chart of a method for determining whether a data service of a terminal device is congested in an embodiment of the present application, and the method in FIG. 3 includes steps S310-S340.

In step S310, the application program in the terminal device initiates a data transmission request.

In step S320, the application data rate is determined.

Wherein, the determination of the data rate of the application program may be to search in a pre-established first database according to the information of the application program, so as to determine the data rate of the current application program.

In some implementations, the first database may be determined in the following manner: counting the peak data rates and network delays of different types of applications in multiple scenarios; taking the average of multiple statistics as the average data rate of the application; The average data rate of multiple application programs is saved in the first database, and the data format in the first database can be:

Tuple A (application, ping delay, uplink throughput, downlink throughput).

The value of the above-mentioned average data rate reflects the requirements of the application on the network transmission capacity. If the current network transmission capacity is lower than this value, the performance of the application may be degraded, such as connection failure or freezing.

In step S330, the network throughput rate of the current serving cell is determined.

Wherein, the network throughput rate may be determined according to parameters such as the bandwidth of the currently registered network and carrier aggregation. Alternatively, the network throughput rate may also be searched in a pre-established second database according to the cell information of the current serving cell to determine the network throughput rate of the previous serving cell,

The above-mentioned second database stores empirical values of network throughput rates of multiple cells, wherein the value corresponding to each cell can be considered as a typical value of the uplink and downlink transmission capabilities of an operator's network under a specific frequency and carrier aggregation configuration .

The data format of the network throughput experience value in the second database is: tuple B (operator PLMN, serving cell RAT/Band, EN-DC combination, NR-CA combination, average Ping delay, average uplink throughput, average downlink throughput).

In the embodiment of the present application, the network throughput corresponding to the current serving cell can be obtained by searching in the second database according to information such as the PLMN, RAT, and carrier aggregation configuration of the current serving cell.

In step S340, it is determined whether the network throughput rate of the current serving cell meets the data rate of the application program. If the current network throughput rate can meet the requirements, it means that the current terminal device is not in a state of data traffic congestion. On the contrary, when the network throughput rate is lower than the data rate of the application program, it means that the current network cannot meet the business needs of the terminal device, and the terminal device is in a state of data traffic congestion. state.

On the basis of the above embodiments, the present application also provides a more detailed congestion processing method, and FIG. 4 is a schematic flowchart of the congestion processing method provided in another embodiment of the present application. The method in Fig. 4 includes steps S401-S407.

In step S401, the application initiates a data request.

In step S402, it is determined whether the current data traffic is congested.

Wherein, the method for determining whether the current data service is congested may refer to FIG. 3 and the foregoing description of the method in FIG. 3 .

When it is determined that the data traffic of the current terminal device is congested, step S403 is executed.

In step S403, the current serving cell is added to the congestion list. In this step, adding the current serving cell to the congestion list can prevent the terminal device from accessing the cell again.

After the current serving cell is added to the congestion list, the target cell is determined among multiple neighboring cells, and the current serving cell is switched to the target cell. Including steps S404-S407.

In step S404, traverse and select multiple first cells, and determine whether there is a target cell satisfying the first condition among the multiple first cells. Wherein, the multiple first cells are multiple neighboring cells that belong to the same public land mobile network (PLMN) as the current serving cell and belong to the same radio access technology (RAT) as the current serving cell. The first condition may be that the network transmission capability of the target cell meets the data service request of the terminal device. When there is a target cell satisfying the first condition in the first cell, step S407 is performed; otherwise, step S405 is performed.

In step S405, traverse and select a plurality of second cells, and determine whether there is a cell satisfying the above-mentioned first condition among the plurality of second cells. Wherein, the multiple second cells are multiple neighboring cells that belong to the same PLMN as the current serving cell and belong to different RATs from the current serving cell. If it exists, execute step S407, otherwise execute step S406.

In step S406, a plurality of third cells are traversed and selected to determine a target cell satisfying the first condition. Wherein, the multiple third cells are multiple neighboring cells that do not belong to the same PLMN as the current serving cell.

It should be noted that when determining the target cell in multiple third cells, it can also be performed according to the priority in the above, for example, you can preferentially choose to traverse the NR cell, and when there is no target cell in the NR cell, then in the LTE The traversal is performed in the cell, so that the target cell has stronger network transmission capability.

In step S407, switch to the target cell.

After the terminal device switches to the target cell, it can also periodically detect the congestion state of the current data service during operation, that is, return to step S402.
