Detailed Description
To make the objects, technical solutions and advantages of the embodiments of the present application clearer, the embodiments of the present application will be described in detail below with reference to the accompanying drawings. However, it will be appreciated by those of ordinary skill in the art that in the examples of the present application, numerous technical details are set forth in order to provide a better understanding of the present application. However, the technical solution claimed in the present application can be implemented without these technical details and various changes and modifications based on the following embodiments. The following embodiments are divided for convenience of description, and should not constitute any limitation to the specific implementation manner of the present application, and the embodiments may be mutually incorporated and referred to without contradiction.
The first embodiment of the invention relates to a frequency point switching method, which updates the capability information of UE according to the historical access information of the frequency point of the UE and switches the frequency point of the UE according to the updated capability information of the UE. Because the actual supporting condition of the UE on the frequency point can be known from the historical access information of the frequency point of the UE, the capability information of the UE is updated according to the historical access information of the frequency point of the UE, the frequency point can be switched according to the actual capability information of the UE, and the switching to the non-supporting frequency point is avoided, so that the condition of frequency point switching failure is reduced, the success rate of frequency point switching is improved, and the user disconnection rate is reduced.
It should be noted that the execution main body of the frequency point switching method provided by the embodiment of the present invention may be a base station, and specifically, may be a base station connected to a UE.
The specific flow of the frequency point switching method provided by the embodiment of the invention is shown in fig. 1, and comprises the following steps:
s101: and updating the capability information of the UE according to the historical access information of the frequency point of the UE.
S102: and switching the frequency points of the UE according to the updated capability information of the UE.
For S101-S102, the detailed description is as follows:
optionally, the capability information of the UE may refer to radio capability information of the UE, and may be stored in the core network or the base station.
In practical application, the frequency point nominally supported by the UE but not actually supported exists, and the historical access information of the frequency point of the UE can indicate whether the UE actually supports or does not support the frequency point, so that the capability information of the UE is updated according to the historical access information of the frequency point of the UE, and the support information of the UE on the frequency point can be truly reflected.
It should be understood that the capability information of the UE may include support information for all frequency points, for example, support for the frequency point a, support for the frequency point B, and the like, and when the capability information of the UE is updated according to the historical access information of the frequency point of the UE, the support information that does not meet the actual situation is updated. For example, if the UE supports the access of the frequency point a in the original capability information of the UE, but the UE does not actually support the frequency point a, the information that the UE does not support the frequency point a is updated to the capability information of the UE; or, if the UE does not support the access of the B-bin in the original capability information of the UE, but actually supports the B-bin, the information that the UE supports the B-bin is updated into the capability information of the UE. If the support information conforms to the actual situation, the support information is maintained unchanged, for example, if the UE supports the access of the C frequency point in the original capability information of the UE, and actually the UE also supports the C frequency point, the capability information of the UE does not need to be updated. The UE capability information comprises an un-updated part and an updated part after being updated, and the frequency point switching of the UE is carried out according to the updated UE capability information, namely the frequency point switching of the UE is carried out according to the un-updated part and the updated part, and the updated part is the frequency point switching of the UE according to the updated information. For example, if the capability information of the UE after the update includes: and if the partial information, namely the supporting information of the frequency point A and the supporting information of the frequency point B, of the updated partial information is not updated, the frequency point switching of the UE is carried out according to the updated capability information of the UE, namely the supporting information of the frequency point A and the supporting information of the frequency point B.
In a specific example, S101 may include: and if the UE is accessed to the problem frequency point, updating the information of the problem frequency point supported by the UE into the capability information of the UE, wherein the problem frequency point is the frequency point with the disconnection rate larger than the preset value.
Optionally, the problem frequency points may be labeled manually, specifically, obtained by operation and maintenance management data, big data, terminal manufacturer feedback, and the like. For example, through statistics of operation and maintenance data, if the user disconnection rate on the D frequency point is greater than a preset value, the D frequency point is marked as a problem frequency point. Optionally, since the remaining frequency points except the problem frequency point are non-problem frequency points, the non-problem frequency points may not be marked additionally.
Because the problem frequency point can cause the UE to be disconnected, the information of the UE supporting the problem is updated to the capability information of the UE, and the frequency point switching of the UE is subsequently carried out according to the updated capability information of the UE, so that the UE can be switched to the problem frequency point which is successfully accessed once, but not to the problem frequency point which is not successfully accessed to cause the disconnection, and the disconnection rate of the UE is reduced.
In a specific example, the updating the information of the frequency points where the UE supports the problem to the capability information of the UE includes: and marking the information of the problem frequency points supported by the UE in the capability information of the UE to obtain the marking capability information of the UE.
Specifically, the information of the frequency points where the UE supports the problem may be added to the capability information of the UE in a form of a label, and the original capability information of the UE remains unchanged.
For example, if the problem frequency point E in the original capability information of the UE is not supported, but the UE can actually access the problem frequency point E, an additional piece of information is added to the capability information of the problem frequency point E by the UE, which indicates that the UE actually supports.
In a specific example, S102 may specifically include: and measuring the frequency point according to the marking capability information of the UE, and switching the frequency point of the UE according to the measurement result of the frequency point.
If the marking capability information of the UE supports a certain problem frequency point, the problem frequency point is measured, and then the frequency point of the UE is switched according to the measurement result; if the labeling capability information of the UE does not contain the support information of a certain problem frequency point, the problem frequency point is not subjected to measurement, and therefore the UE is prevented from being switched to the problem frequency point to cause disconnection.
Because the base station accessed by the UE may change, in order to enable the base station accessed by the UE to conveniently obtain the updated capability information of the UE, optionally, the capability information of the UE is updated according to the historical access information of the frequency point of the UE, which may specifically include: and updating the capability information of the UE in the core network according to the historical access information of the frequency point of the UE. In this way, even if the base station accessed by the UE changes, the UE can acquire the updated capability information of the UE from the core network.
Optionally, if the frequency point of the UE is switched to inter-station switching, the updated capability information of the UE is transmitted from the base station before UE switching to the base station after UE switching when the frequency point of the UE is switched. Thus, the base station after switching can obtain the updated capability information of the UE without acquiring the capability information from the core network.
Particularly, when the UE is restarted or re-accessed for a long time, the base station may not be able to acquire updated capability information of the UE from the core network, for example, the capability information of the UE needs to be re-updated according to the historical access information of the frequency point of the UE, if the capability information of the UE cannot be acquired due to the fact that the information of the frequency point currently supported by the UE in the core network is expired.
In order to more clearly explain the above process, a specific example is described below. Please refer to fig. 2, which is a diagram illustrating a frequency point switching method according to an embodiment of the present invention.
Specifically, frequency points Freq F4 of Cell (Cell) L4 and frequency points Freq F5 of Cell L5 are non-problem frequency points, and frequency points Freq F1, Freq F2 and Freq F3 are problem frequency points that users may drop due to the error of the UE supporting frequency band capability;
1. if the UE is in Cell L1 at the beginning, the UE tries to access a problem frequency point Freq F1 corresponding to Cell L1; if the access is successful, the UE actually supports the problem frequency point Freq F1;
2. the method comprises the steps that the supporting information of a problem frequency point Freq F1 is updated to the capability information of UE in a core network, meanwhile, Cell L1 only issues operations such as measurement and switching to the problem frequency point Freq F1, non-problem frequency points Freq F4 and Freq F5, and does not issue operations such as measurement and switching to the problem frequency points Freq F2 and Freq F3, so that the UE is prevented from being disconnected due to the fact that the UE is accessed to the problem frequency points Freq F2 and Freq F3;
3. if the UE is located in Cell L2 after being released from Cell L1, the UE can try to access to a problem frequency point Freq F2;
4. if the access is successful, the UE actually supports the problem frequency point Freq F2, and the UE capability information of the core network is acquired, and the problem frequency point Freq F2 is not indicated to be supported, the UE capability information is updated to the core network, and the information of the problem frequency point Freq F2 supported by the UE is updated to the UE capability information of the core network; meanwhile, Cell L2 issues operations such as measurement and switching to the problem frequency point Freq F1, the problem frequency point Freq F2, the non-problem frequency point Freq F4 and the non-problem frequency point Freq F5, without measuring the problem frequency point Freq F3;
5. if the UE is handed over from Cell L2 to Cell L4, the base station of Cell L2 may transmit the updated capability information of the UE to the base station of Cell L4 in the Cell of the handover request; according to the transmitted information, Cell L4 can know that the UE supports problem frequency points Freq F1 and Freq F2, and then can issue measurement and switching operations to problem frequency point Freq F1, problem frequency point Freq F2, non-problem frequency point Freq F4 and non-problem frequency point Freq F5, but not measure problem frequency point Freq F3, so as to avoid the UE from being switched to problem frequency point Freq F3 to cause drop.
According to the frequency point switching method provided by the embodiment of the invention, the capability information of the UE is updated according to the historical access information of the frequency point of the UE, and the frequency point switching of the UE is carried out according to the updated capability information of the UE. Because the actual supporting condition of the UE on the frequency point can be known from the historical access information of the frequency point of the UE, the capability information of the UE is updated according to the historical access information of the frequency point of the UE, the frequency point can be switched according to the actual capability information of the UE, and the switching to the non-supporting frequency point is avoided, so that the condition of frequency point switching failure is reduced, the success rate of frequency point switching is improved, and the user disconnection rate is reduced.
A second embodiment of the present invention relates to a frequency point switching method, and is substantially the same as the first embodiment except that: in the embodiment of the present invention, updating the capability information of the UE according to the historical access information of the frequency point of the UE includes: acquiring historical access information of a frequency point of UE and the moving speed of the UE; and updating the capability information of the UE according to the historical access information of the frequency point of the UE and the moving speed of the UE.
A specific flow of the frequency point switching method provided by the embodiment of the present invention is shown in fig. 3, and includes the following steps:
s201: and acquiring historical access information of the frequency point of the UE and the moving speed of the UE.
S202: and updating the capability information of the UE according to the historical access information of the frequency point of the UE and the moving speed of the UE.
S203: and switching the frequency point of the UE according to the updated capability information of the UE.
For S201-S203, the details are as follows:
since the historical access information of the frequency point of the UE has been described in the first embodiment, the moving speed of the UE is mainly described in the embodiment of the present invention, and for the part performing the frequency point switching of the UE according to the historical access information of the frequency point of the UE, reference may be made to the related description in the first embodiment, which is not repeated here.
It can be understood that, when the UE is at a low speed, for example, stationary or the user has a slow moving speed, the moving speed of the UE is slow, and the UE has sufficient time to measure the frequency point; at this time, a relatively strict switching parameter may be set, for example, the frequency point may be switched when the service quality of the adjacent frequency point is detected to be better than the service quality of the frequency point by a preset threshold, or the frequency point may be switched when the service quality of the adjacent frequency point is detected to be better than the service quality of the frequency point by a preset threshold and the duration reaches a preset time period, so as to ensure that the frequency point obtains a relatively stable service quality before and after switching. When the UE is in a train running at a high speed, the moving speed of the UE will be very fast, and accordingly, the switching of the frequency points (cells) will be very frequent, and if the UE is still switched according to a switching parameter with a relatively strict low speed, the UE may be switched too late to cause a switching failure, which causes a drop, for example, the UE may not perform the switching because the UE is not directly subjected to the requirement of the switching parameter; therefore, when the UE moves faster, the handover parameters need to be set more loosely so that the UE can handover smoothly, for example, the preset threshold is adjusted lower, or the duration is shortened. In addition, the loose handover parameters at high speed may not be suitable for the low speed, because if the handover parameters corresponding to high speed are used at low speed, the UE may prematurely meet the requirement of the handover parameters, and the frequency point corresponding to the handover target may not be suitable for the UE, resulting in premature handover failure of the UE.
Alternatively, the moving speed of the UE may be evaluated by the base station or the core network through the following relevant information of the UE: historical cell information, frequency offset or dwell duration, etc. Specifically, the base station or the core network may calculate the number of cells switched by the UE in unit time according to the historical cell information and the residence time of the UE, and evaluate the moving speed of the UE according to the number of cells switched by the UE in unit time; or the base station estimates the moving speed of the UE according to the residence time of the UE, for example, if the residence time of the UE is short, the moving speed of the UE is estimated to be high; and if the residence time of the UE is longer, evaluating the moving speed of the UE to be low speed.
The base station accessed by the UE may change, especially when the moving speed of the UE is high, the information of the moving speed of the UE is stored in the core network, and when the UE is accessed next time, the information of the moving speed of the UE is obtained from the core network. When the moving speed of the UE changes, the base station or the core network updates information of the moving speed of the UE in the core network.
Optionally, the moving speed of the UE may be divided into a plurality of different categories, and then different handover parameters are set according to the different categories, so that when the UE is in different moving speeds, the UE is handed over according to the appropriate handover parameters. For convenience of explanation, the following description will be given taking an example in which the moving speed of the UE is classified into two categories, high speed and low speed. Specifically, the moving speed of the UE is divided into two categories, namely a high speed and a low speed, and different handover parameters of the UE are set according to the two categories, where the high speed is greater than a preset speed threshold, and the low speed is less than or equal to the preset speed threshold. When the base station acquires the moving speed of the UE, if the moving speed of the UE is high speed, setting a switching parameter corresponding to the high speed for the UE; if the moving speed of the UE is low speed, the switching parameters corresponding to the low speed are set for the UE, so that the UE can adapt to two scenes of high speed and low speed when the frequency point is switched, and the phenomenon that the UE fails to switch due to unreasonable switching parameters to cause disconnection can be avoided.
After the base station acquires the information of the moving speed of the UE, the moving speed of the UE can be continuously evaluated, if the moving speed of the UE changes, the changed moving speed of the UE is used for updating the capability information of the UE in the core network, and then the switching parameters of the UE are reconfigured according to the changed moving speed of the UE.
In a specific example, if the moving speed of the UE is high (greater than a preset speed threshold), when the UE disconnects and re-accesses, the previously acquired moving speed of the UE is used as the current moving speed configuration switching parameter of the UE. Because the moving speed of the UE is not changed on a large scale before the UE is disconnected and after the UE is reconnected, if the moving speed of the UE is re-evaluated first during the re-accessing, the UE may fail to be switched due to unreasonable switching parameters to cause a drop during the re-evaluating of the moving speed of the UE; therefore, when the UE is disconnected and re-accessed, the moving speed of the UE is still regarded as high speed to configure the switching parameters, the UE can be switched according to the high-speed switching parameters, and the high-speed switching parameters are compatible with the high-speed state and the low-speed state, so that the UE can be ensured not to be disconnected due to UE switching failure caused by unreasonable switching parameters during the period of obtaining the re-evaluation result of the moving speed of the UE. Of course, regardless of whether the UE moves at a high speed or a low speed before disconnection, when the UE is disconnected and resumed, the handover parameters may be configured at a high speed according to the moving speed of the UE.
When the frequency point of the UE is switched to the inter-station switching, the information of the moving speed of the UE can be transmitted to the base station after the UE is switched when the frequency point of the UE is switched, so that the base station after the UE is switched can obtain the moving speed of the UE without acquiring the moving speed of the UE in a core network.
In order to more clearly explain the above process, a specific example is described below. Please refer to fig. 4, which is a diagram illustrating a frequency point switching method according to an embodiment of the present invention. Since the procedure of performing the frequency point handover of the UE according to the historical access information of the frequency point of the UE has been described in the first embodiment, only the procedure of configuring the handover parameter according to the moving speed of the UE will be described here.
1. The UE accesses a base station of the Cell L1;
2. the base station of the Cell L1 evaluates the moving speed of the UE, and if the evaluation result is high speed, the base station configures switching parameters corresponding to the high speed for the UE;
3. the base station of the Cell L1 updates the information that the UE has a high moving speed to the core network;
4. the UE disconnects the base station accessed to the Cell L2 from the base station of the Cell L1;
5. when the base station of the Cell L2 acquires that the movement speed of the UE is high from the core network, configuring a switching parameter corresponding to the high speed for the UE, and meanwhile, continuously evaluating the movement speed of the UE;
6. if the result of the reevaluation is low speed, the base station of Cell L2 configures a switching parameter corresponding to the low speed for the UE;
7. the base station of the Cell L2 updates the moving speed of the UE in the core network to be low speed;
8. switching the UE from the base station of the Cell L2 to the base station of the Cell L3, and transmitting information that the movement speed of the UE is low to the base station of the Cell L3 in a switching request by the base station of the Cell L2;
9. the base station of Cell L3 configures a handover parameter corresponding to a low speed for the UE, in response to the UE moving at a low speed.
According to the frequency point switching method provided by the embodiment of the invention, the historical access information of the frequency point of the UE and the moving speed of the UE are acquired, the capability information of the UE is updated according to the historical access information of the frequency point of the UE and the moving speed of the UE, and then the frequency point switching of the UE is carried out according to the updated capability information of the UE, so that the switching can be carried out by combining the moving speed of the UE on the basis of the historical access information of the frequency point of the UE, the switching parameter is matched with the moving speed of the UE when the UE is switched over at the frequency point, the situations of switching failure and disconnection caused by too early or too late switching due to unreasonable switching parameters are avoided, and the disconnection rate of a user can be further reduced.
In addition, those skilled in the art can understand that the steps of the above methods are divided for clarity, and the implementation can be combined into one step or split into some steps, and the steps are divided into multiple steps, so long as the same logical relationship is included, and the method is within the protection scope of the present patent; it is within the scope of the patent to add insignificant modifications to the algorithms or processes or to introduce insignificant design changes to the core design without changing the algorithms or processes.
