Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, not all, embodiments of the present invention. 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 invention.
Fig. 1 shows a flow chart of a parameter adjustment method according to an embodiment of the present invention, where the method is applied to a terminal, and the method includes:
if the terminal is switched among a plurality of cells, determining one cell in the plurality of cells as a main cell of the terminal; wherein at least two cells of the plurality of cells are pilot frequency cells;
adjusting at least one parameter of a plurality of communication parameters of the terminal to increase the receiving performance value of the terminal at the frequency point corresponding to the main cell;
and if the preset stop condition is reached, stopping parameter adjustment.
The embodiment of the invention realizes the improvement of the receiving performance value of the terminal by adjusting the communication parameters of the terminal, thereby improving the cell switching threshold value of the terminal and preventing frequent switching.
In an embodiment of the present invention, at least two cells in the plurality of cells are inter-frequency cells. In the field, cells with the same frequency point may be referred to as intra-frequency cells, and cells with different frequency points may be referred to as inter-frequency cells. The embodiment of the invention improves the receiving performance value of the terminal under a certain frequency point by adjusting the parameters of the terminal, thereby preventing the terminal from being switched from a service cell to other cells. Through intensive research by the inventor of the application, the switching behavior of the terminal can be controlled to a certain extent by adjusting the self parameter setting of the terminal.
The parameter adjustment method of the embodiment of the invention is more suitable for preventing the switching of the terminal between the different frequency cells, and the reason is that:
if the first cell and the second cell are assumed to be co-frequency cells, the first cell and the second cell both correspond to the first frequency point, the first cell and the third cell are pilot frequency cells, and the third cell corresponds to the third frequency point, after the parameter adjustment is performed by using the embodiment of the present invention, on one hand, if the reception performance value of the terminal at the first frequency point is improved, it means that the reception performance values of the terminal at the first cell and the second cell can both be improved, that is, it is difficult to distinguish the situations of the first cell and the second cell, so that the handover of the terminal between the first cell and the second cell cannot be affected.
On the other hand, after the parameter adjustment, if the reception performance value of the terminal at the third frequency point is not necessarily improved, and may not be changed or reduced, the reception performance value of the terminal at the first cell is larger than the reception performance value at the third cell, the terminal will not be handed over to the third cell, and the purpose of preventing the handover can be achieved.
Therefore, the parameter adjustment in the embodiment of the present invention is more applicable to the inter-frequency cells, and the number of the inter-frequency cells in the embodiment of the present invention is not particularly limited, and may be two inter-frequency cells, or may also be multiple cells, for example, three, four, six or more, where at least two cells exist in the multiple cells.
In the embodiment of the present invention, there may be a plurality of ways for adjusting the communication parameters of the terminal, which are not limited herein because: taking a communication parameter set QCN parameter set of a terminal as an example, where the communication parameter set QCN parameter set includes a plurality of parameters, the number of the parameters may be as many as several tens, and the QCN parameter sets in different frequency bands (bands) are different, and adjusting one or more of the parameters may be regarded as adjusting the QCN parameter set. The same applies to other communication parameters of the terminal. Therefore, the embodiment of the present invention does not limit the specific way of adjusting the parameters.
In an embodiment of the present invention, first, it is determined whether handover of a terminal between a plurality of cells satisfies a first handover decision condition. In the case that the handover between the plurality of cells satisfies the first handover decision condition, it may be considered that frequent cell handover occurs in the terminal, that is, determining one cell among the plurality of cells as a primary cell of the terminal, such as ping-pong handover, is performed. Specifically, if the number of times that the terminal switches among the plurality of cells is greater than or equal to a preset threshold value within a first preset time period, the terminal is considered to be frequently switched.
Then, one or more communication parameters of the terminal are adjusted, so as to increase the reception performance value of the terminal at the frequency point corresponding to the main cell, for example, the performance value is increased by 1dB, and as the reception performance value of the terminal at the main cell is increased, the switching threshold is correspondingly increased, the terminal does not switch when the switching threshold is not reached, and the frequent switching is suppressed.
After the communication parameters are adjusted for the first time, if the frequent switching condition is restrained, the parameter adjustment is stopped; if the terminal is switched again after the communication parameters are adjusted for the first time, the preset second switching judgment condition is met, and the terminal is still in a frequent switching state, the communication parameters need to be continuously adjusted, and the receiving performance value of the terminal is improved so as to improve the switching threshold; the process is repeated until the time length of the terminal staying in the main cell is greater than or equal to the preset time length, the terminal is considered to be successfully staying in the main cell, and the parameters do not need to be continuously adjusted.
And appropriate stopping conditions can be set according to requirements, and the adjustment of the communication parameters of the terminal is stopped after the stopping conditions are met. In some embodiments of the present invention, if the number of adjustments to the communication parameters has reached a predetermined number, for example, 10, 15, 50 or more, and the terminal has not successfully camped on the primary cell, in this case, to avoid the consumption of human resources and material data, the communication parameters may not be adjusted any more, and the communication parameters may be restored to the initial values.
In other embodiments of the present invention, after the terminal successfully camps on the primary cell, if the terminal does not perform cell handover again within the third predetermined time period, it may be considered that the terminal is less likely to perform frequent handover again, and the communication parameters may be restored to the initial values.
The embodiment of the invention does not need to send configuration at the network side, and the embodiment of the invention can enable the Receiving performance value of the terminal on a specific frequency point to be higher by adjusting the parameter setting of the terminal under the condition that the terminal is frequently switched, for example, on the premise of not changing the demodulation performance of the terminal, the communication parameter is modified to improve the value of Reference Signal Receiving Power (RSRP) measured by the terminal in a downlink way, and the RSRP value reported by the terminal is improved to make the terminal more difficult to meet the threshold for triggering cell switching, thereby achieving the purpose of inhibiting the cell switching.
The following describes a specific implementation procedure of the parameter adjustment method according to the embodiment of the present invention by using a plurality of specific embodiments.
Example 1
The following describes a specific processing procedure of the parameter adjustment method according to the embodiment of the present invention with reference to fig. 2.
S101, determining whether the terminal A enters a connection state (CONNECT), and if the terminal A enters the connection state, executing the next step S102;
when the terminal needs to perform service, the terminal enters a connection state, and interacts with a network and processes data transmission; when the terminal has no service, the terminal enters an IDLE state (IDLE) and monitors paging and other messages sent by the network;
s102, after a terminal A enters a cell (marked as a cell I), if the terminal A is switched between two different-frequency cells (such as the cell I and a cell II) and meets a first ping-pong switching judgment condition, determining that the terminal A is subjected to ping-pong switching, and executing the next step S103;
in the embodiment of the present invention, the first ping-pong handover decision condition may be: within a first preset time (for example, 60s), the number n of times that the terminal a performs back-and-forth handover between two different frequency cells is greater than or equal to a preset threshold (for example, 5 times), and the terminal a is considered to have ping-pong handover;
the terminal A increases the number n of the switching back and forth by 1 every time the terminal A switches between two different frequency cells;
s103, selecting one cell from the cell I and the cell II which are subjected to ping-pong handover as a main cell of the terminal A, and executing the next step S104;
in the embodiment of the present invention, a cell in which the terminal a resides when the first ping-pong handover decision condition is satisfied, for example, a cell I, may be used as a primary cell;
in the embodiment of the present invention, one cell, for example, cell II, may also be designated as a primary cell in cell I and cell II;
the mode of designating the primary cell can be designated according to a preset condition or randomly designated;
s104, taking the cell I as a main cell as an example, and improving the receiving performance value of the terminal A at the frequency point corresponding to the main cell I by 1dB by adopting a mode of adjusting QCN;
then, if the terminal A is switched between the cell I and the cell II and meets the second ping-pong switching judgment condition, the receiving performance value of the frequency point corresponding to the main cell I is improved by 1dB again;
in the embodiment of the present invention, the second ping-pong handover determination condition may be: within a second predetermined time (for example, 10s), after the terminal a is switched from the primary cell I to the cell II, it is switched back to the primary cell I;
repeating the processing of S104, and gradually improving the receiving performance value until the terminal A successfully resides in the main cell I;
alternatively, the first and second electrodes may be,
repeating the processing of S104, gradually increasing the receiving performance value until the number of times of adjusting the QCN reaches a predetermined number of times (e.g., 15 times), and the terminal a does not successfully reside in the primary cell I, and then restoring the QCN parameter of the terminal a to the initial setting;
alternatively, the first and second electrodes may be,
and repeating the processing of the step S104, gradually increasing the receiving performance value until the terminal a successfully resides in the primary cell I, and if the cell switching does not occur again after a third predetermined time (for example, 180S), restoring the QCN parameter of the terminal a to the initial setting.
In the embodiment of the invention, the lifting can be carried out by taking 1dB as the minimum step; the boost can be maximally stepped by 5 dB.
According to the embodiment of the invention, the receiving performance value on the frequency point of the main cell of the terminal is gradually improved by adjusting the QCN of the terminal, and the measurement report value of the terminal is improved, so that the terminal is not easy to trigger the threshold of cell switching, thereby reducing frequent switching and achieving the effect of reducing ping-pong switching of the terminal.
Example 2
The main difference between this embodiment and embodiment 1 is that the terminal B in this embodiment performs ping-pong handover between a plurality of inter-frequency cells, and three inter-frequency cells (cell I, cell II, and cell III) are taken as an example for description below.
In this embodiment, the first ping-pong handover determination condition is: in a first preset time length, the switching times n of the terminal B among the three different-frequency cells are greater than or equal to a preset threshold value, and the terminal B is considered to have ping-pong switching;
the terminal B increases the switching times n by 1 every time the terminal B switches in three different frequency cells;
in this embodiment, the second ping-pong handover determination condition is: within a second preset time, the terminal B is switched from the main cell I to the cell II and then is switched back to the main cell I;
in this embodiment, the second ping-pong handover determination condition may further be: within a second preset time, the terminal B is switched to the cell III after being switched from the main cell I to the cell II;
based on the first ping-pong handover determination condition and the second ping-pong handover determination condition of this embodiment, the receiving performance value of the terminal B at the frequency point corresponding to the primary cell I is improved by adjusting the QCN until the terminal B successfully resides in the primary cell I, or if the terminal B does not successfully reside in the primary cell I after the QCN is adjusted for the predetermined number of times, the QCN parameter of the terminal B is restored to the initial setting.
Example 3
In this embodiment, the tracking area code TAC of the cell I is different from the TAC of the cell II. When the terminal C switches from the cell I to the cell II, it finds that the TAC changes, the terminal C actively initiates a Tracking Area Update TAU request (Tracking Area Update request) to the network to notify the network, as shown in fig. 3, the terminal reports an effect schematic diagram, and the terminal C reports a measurement report MR until the TAU Update is completed.
The terminal C needs to perform frequent data interaction with the network in the above process.
At this time, the terminal C performs ping-pong handover between the inter-frequency cell I and the cell II, and each handover triggers the terminal C to initiate a TAU request, so that the TAU requests increase rapidly, the terminal C cannot perform effective data transmission, and power consumption of the terminal increases.
In this case, the terminal C executes the parameter adjusting method according to the embodiment of the present invention, which specifically includes:
s201, determining that the terminal C is in a CONNECT state;
s202, after entering a cell I, a terminal C is switched between the cell I and a cell II, and within 30S, the number of times that the terminal C is switched back and forth between the cell I and the cell II is 6, so that a first ping-pong switching judgment condition is met, and the ping-pong switching of the terminal C is determined;
s203, the terminal C resides in the cell I when the first ping-pong handover judgment condition is met, so that the cell I is taken as a main cell;
s204, improving the receiving performance value of the terminal A at the frequency point corresponding to the main cell I by 1dB in a QCN adjusting mode; the terminal C is switched from the cell I to the cell II and then is switched back to the main cell I, the time consumption is 8s, and if the second ping-pong switching judgment condition is met, the receiving performance value of the terminal A at the frequency point corresponding to the main cell I is improved by 1dB again;
repeating S204, after adjusting QCN of terminal C for the 6 th time, terminal C successfully camps on primary cell I, and then may enter IDLE state.
In the embodiment of the invention, the ping-pong switching of the terminal C between the cell I and the cell II is stopped by adjusting the QCN of the terminal C, and the terminal C does not need to initiate a TAU request to the network due to the cell switching, as shown in FIG. 4, which is beneficial to improving the effective data transmission of the terminal C, improving the communication quality and avoiding unnecessary electric quantity consumption.
