Detailed Description
The technical solutions in the embodiments of the present application will be described clearly below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are some, but not all, embodiments of the present application. All other embodiments, which can be derived from the embodiments in the present application by a person skilled in the art, are within the scope of protection of the present application.
The terms first, second and the like in the description and in the claims of the present application are used for distinguishing between similar elements and not necessarily for describing a particular sequential or chronological order. It will be appreciated that the data so used may be interchanged under appropriate circumstances such that embodiments of the application are capable of operation in sequences other than those illustrated or described herein, and that the terms "first," "second," etc. are generally used in a generic sense and do not limit the number of terms, e.g., a first term can be one or more than one. In addition, "and/or" in the specification and claims means at least one of connected objects, a character "/" generally means that a preceding and succeeding related objects are in an "or" relationship.
For the convenience of understanding, some contents related to the embodiments of the present application are explained below.
With the development and acceleration of the construction of 5G networks, the wireless spectrum resources of operators are increasingly strained. In order to solve the problem of shortage of wireless spectrum resources of operators, the trend of sharing networks by operators is more and more obvious. The operator can enhance the network coverage and reduce the network laying cost by using the shared network. Specifically, the operator may implement sharing of the network by sharing the base station or sharing the cell.
In this embodiment, the shared cell may be connected to the NSA as an anchor cell, where the anchor cell is a dual-connection cell supporting a Long Term Evolution (LTE) technology and a New Radio (NR) technology. Accordingly, the shared cell may also be referred to as a shared anchor cell.
When the operator lays the network, the terminal can be connected with 5G as much as possible according to the 5G support capability of the terminal equipment. When the terminal device starts the 5G capability and reports the 5G capability to the cell registered therein, the following situations may occur: 1) If the terminal equipment registers the shared anchor point cell, the shared anchor point cell does not configure the measurement of the non-shared anchor point cell, so that the terminal equipment cannot escape from the shared anchor point cell. 2) The terminal equipment is registered in the non-shared anchor point cell, and the terminal is configured in the non-shared anchor point cell and is easier to switch to the shared anchor point cell. When the terminal turns off the 5G capability, the terminal device is more likely to register with the non-shared anchor cell.
For ease of understanding, examples are illustrated below:
for a scenario in which the terminal device opens 5G, the terminal device may register in the shared anchor Cell a and connect to the 5G Cell C of NSA through a Secondary Cell Group (SCG). Cell a is not configured with the measurement of non-shared anchor cell B, only with the 5G SCG measurement.
For the scenario that the terminal device turns off 5G, the terminal device may register in the non-shared anchor cell B. The cell B network does not configure the measurement of the shared anchor cell a.
Therefore, when the 5G capability is started, the terminal equipment is easy to register to the shared anchor point cell; when the terminal equipment closes the 5G capability, the terminal equipment is easy to escape from the shared anchor point cell and register to the non-shared anchor point cell.
After registering to the shared anchor cell, the terminal device may borrow the shared anchor cell to connect to the NSAA. However, with the fast deployment of SA networks, the NSA is gradually reduced, and a situation may occur in which the shared anchor cell cannot access the NSA. On the other hand, a part of the shared network may limit the shared resources, and generally may limit the scheduling bandwidth of the shared terminal device, for example, only less than 20% of the resources may be scheduled as shared resources. Therefore, if the terminal equipment cannot access the NSA by using the shared cell and the scheduling resource is limited, the abnormal problems of low rate, network jamming, flow cutoff and the like occur, and the communication quality is poor.
In order to make communication of a terminal device in a shared network area smoother and to improve communication quality of the terminal device, embodiments of the present application provide a cell selection method, where when the terminal device starts a 5G capability to register in a shared cell but is not connected to a 5G auxiliary cell group, a target operation may be executed according to a processing policy corresponding to the shared cell, so that the terminal device registers in a cell with better communication quality. Therefore, the terminal equipment can escape from the shared cell which can not be accessed to the NSA, so that the communication stability of the terminal equipment can be improved, and the communication quality of the terminal equipment is improved.
The cell selection method provided in the embodiments of the present application is described in detail below with reference to the accompanying drawings through specific embodiments and application scenarios thereof.
Fig. 1 is a flowchart of a cell selection method according to an embodiment of the present application. The cell selection method provided by the embodiment of the application can be applied to terminal equipment, and in practical application, the terminal equipment can be a mobile phone, a computer or a mobile station.
As shown in fig. 1, the cell selection method may include:
In an embodiment of the present application, the first cell is a shared cell of at least two operators. After registering with the first cell, the terminal device may connect to the 5G SCG through the first cell, and thus it may be understood that the first cell may be the aforementioned shared anchor cell.
And the terminal equipment starts the 5G capability to register to the first cell. Specifically, the terminal device may start the 5G capability and report the 5G capability to the network, and the network may configure the terminal device to register in the first cell by querying the 5G capability of the terminal device. The terminal device may identify whether the operator to which the terminal device belongs and the operator to which the registered frequency point belongs are the same operator through a Public Land Mobile Network (PLMN), to determine whether to register the shared anchor point cell, and if not, may determine to register the shared anchor point cell.
It is to be understood that the terminal device is any terminal device registered to the first cell.
The terminal equipment is not connected with a 5G auxiliary cell group, and shows that: the terminal device is not connected to the 5G network of NSA. In one implementation, the terminal device may determine whether to connect to the 5G SCG by detecting whether an evolved universal terrestrial radio access network-new air interface Dual Connectivity (E-UTRAN-NR Dual Connectivity, endec) identity is displayed. If the ENDC mark is displayed, determining to connect to the 5G SCG; if the ENDC flag is not displayed, it is determined that 5G SCG is not connected.
In this case, if the terminal device continues to camp in the first cell, the terminal device cannot connect to the 5G network, and thus a problem of communication abnormality is likely to occur. Therefore, in order to ensure the communication fluency of the terminal device, the terminal device can escape from the first cell and register to the target cell.
In this embodiment, the terminal device may obtain a processing policy corresponding to the first cell, so as to execute a target operation according to the processing policy, escape from the first cell, and register to a target cell.
In some embodiments, the processing policy corresponding to the first cell may be sent to the terminal device by a server, and the terminal device may receive and acquire the processing policy corresponding to the first cell. The server may determine the processing policy corresponding to the first cell based on the number of the most recently collected abnormal events of the first cell within a preset time duration. In this way, the processing strategy corresponding to the first cell can be matched with the current situation of the first cell, and the reliability of communication processing can be improved.
In other embodiments, the processing policy corresponding to the first cell may be predefined in a protocol, and the terminal device may obtain the processing policy corresponding to the first cell by reading the protocol. Therefore, the terminal equipment does not need to interact with other equipment to acquire the processing strategy, and therefore signaling overhead can be saved.
And for the processing strategy for forbidding the first cell, the fact that the terminal equipment can be registered to other shared cells by escaping from the first cell is shown, and the communication quality of the terminal equipment is improved.
For the processing strategy of closing the 5G capability of the terminal device registered to the first cell, it indicates that a problem occurs in the network of the shared network area, and even if the terminal device escapes from the first cell and registers to another shared cell, the communication quality of the terminal device cannot be improved, so that the terminal device can register to a non-shared cell by closing the 5G function, and the communication quality of the terminal device is improved.
And 102, executing target operation according to the processing strategy so as to enable the terminal equipment to be registered to a target cell, wherein the communication quality of the terminal equipment in the target cell is higher than that of the terminal equipment in the first cell.
In an embodiment of the present application, the target operation may include at least one of: disabling the first cell; and closing the 5G function of the terminal equipment.
The target operation specifically executed by the terminal device may be determined based on the specific representation of the processing policy.
In the case that the processing policy only includes disabling the first cell, the terminal device may disable the first cell and register with a second cell to improve communication quality of the terminal device. In this case, the target operation is to disable the first cell, the target cell being the second cell. Since the 5G function of the terminal device is still turned on at this time, it can be known from the foregoing that the probability that the second cell is the shared cell is higher.
In a case that the processing policy only includes the 5G capability of the terminal device registered in the first cell being turned off, the terminal device may turn off the 5G function of the terminal device and register the terminal device in a third cell, so as to improve the communication quality of the terminal device. In this case, the target operation is to turn off the 5G function of the terminal device, and the target cell is a third cell. Since the 5G function of the terminal device is turned off at this time, it can be known from the foregoing that the probability that the second cell is a non-shared cell is high.
In a case that the processing policy includes disabling the first cell and turning off a 5G capability of a terminal device registered to the first cell, in one implementation, the terminal device may first disable the first cell and register to a second cell; then, whether the communication quality of the first terminal in the second cell reaches a preset index or not can be detected; in case of an arrival, may camp on the second cell; and if the number of the mobile terminals does not reach the preset value, the 5G function of the terminal equipment can be closed, and the terminal equipment is registered to the third cell. In another implementation manner, the terminal device may directly close the 5G function of the terminal device, and register to the third cell.
In the cell selection method in the embodiment of the present application, when the terminal device starts the 5G capability to register in the shared cell but is not connected to the 5G secondary cell group, the target operation may be executed according to the processing policy corresponding to the shared cell, so that the terminal device registers in the cell with better communication quality. Therefore, the terminal equipment can escape from the shared cell which can not be accessed to the NSA, so that the communication stability of the terminal equipment can be improved, and the communication quality of the terminal equipment is improved.
In some embodiments, before performing the target operation according to the processing policy, the method may further include:
obtaining first information, the first information comprising at least one of: the resource scheduling condition of the terminal equipment, the communication condition of the terminal equipment and the available adjacent cell condition of the terminal equipment;
the executing the target operation according to the processing policy may include:
and executing target operation according to the first information and the processing strategy.
In this embodiment, the resource scheduling condition of the terminal device may be represented as: resource scheduling is abnormal; or the resource scheduling is normal.
The resource scheduling condition of the terminal device can be characterized by at least one of the following:
the quantity of uplink data of the terminal equipment within a certain time length;
the number of downlink data of the terminal equipment within a certain time length;
a time delay of a Transmission Control Protocol (TCP) packet of the terminal device.
Determining a resource scheduling anomaly for the terminal device if at least one of:
the quantity of the uplink data is less than or equal to the uplink data threshold value;
the quantity of the downlink data is less than or equal to the threshold value of the downlink data;
the delay of the TCP packet is greater than the delay threshold.
The communication condition of the terminal device can be represented as: communication is abnormal; or, the communication is normal.
The communication condition of the terminal equipment can be characterized by at least one of the following items:
the blocking times of data transmission of the terminal equipment within a certain time length;
and the network disconnection times of the terminal equipment within a certain time length.
The communication anomaly of the terminal device may be determined if at least one of the following is satisfied:
the number of times of clamping is greater than the threshold value of the number of times of clamping;
the network breaking times are larger than the threshold value of the network breaking times.
The available neighboring cell condition of the terminal device may be represented as: the terminal equipment has available adjacent cells; or, the terminal device does not have an available neighboring cell.
In this embodiment, the terminal device may further perform the target operation in combination with one or more of the above conditions of the terminal device on the basis of the processing policy, so that the performed target operation may better meet the actual requirement of the terminal device, and the reliability of the communication processing may be improved.
In an optional implementation manner, the performing a target operation according to the first information and the processing policy may include:
disabling the first cell if a first condition is satisfied;
wherein the first condition comprises:
the processing policy comprises disabling the first cell;
the resource scheduling condition indicates that the resource scheduling of the terminal equipment is abnormal;
and the available adjacent cell condition indicates that the terminal equipment has an available adjacent cell.
In this embodiment, the first terminal may disable the first cell and register in the second cell only when the processing policy of the first cell includes that the first cell is disabled and the resource scheduling of the terminal device in the first cell is abnormal and the terminal device can search for an available neighboring cell in the first cell; otherwise, camping on the first cell may continue. Therefore, the terminal equipment can be guaranteed to have the requirement of escaping from the first cell really, namely, the strategy of forbidding the first cell is suitable for the terminal equipment, and the terminal equipment can escape from the first cell only under the condition that the terminal equipment has the available adjacent cells, so that the cell reselection of the terminal equipment can be avoided when the cell reselection is not needed, and the communication fluency of the terminal equipment can be improved.
It should be noted that, the embodiment of the present application does not limit the execution order of the following determination operations: determining whether a processing policy of the first cell includes disabling the first cell; determining whether resource scheduling of the terminal equipment is abnormal; and determining whether the terminal equipment has an available adjacent cell.
In an alternative implementation, the terminal device may determine whether resource scheduling of the terminal device is abnormal after determining that the processing policy of the first cell includes disabling the first cell.
And under the condition that the resource scheduling of the terminal equipment is abnormal, determining whether the terminal equipment has an available adjacent cell. Under the condition that the terminal equipment has the available adjacent cell, the terminal equipment can escape from the first cell and register to the available adjacent cell. Under the condition that the terminal equipment does not have an available adjacent cell, the communication quality of the shared area network is poor, if the terminal equipment starts the 5G function, the terminal equipment cannot solve the problem of abnormal communication even if the terminal equipment is registered in other cells, and the terminal equipment can stop the 5G function and register the terminal equipment in a third cell.
Under the condition that the resource scheduling of the terminal device is normal, it is indicated that the terminal device can normally communicate in the first cell, that is, the strategy of disabling the first cell is not applicable to the terminal device, and can continue to reside in the first cell.
In the case of disabling the first cell, in one implementation, the terminal device may permanently disable the first cell.
In another implementation, after disabling the first cell, the method may further include:
and under the condition that the forbidding duration of the first cell reaches a first duration, the forbidding of the first cell is released.
In an alternative implementation manner, the terminal device may set a timer, and determine whether the forbidden duration of the first cell reaches the first duration through the timer. In this way, the first electronic device may start the timer while the first cell is disabled, and set the duration of the timer to the first duration, and in case that the timer is overtime, the first cell may be disabled.
In this implementation, the terminal device may release the first cell from being disabled after the first cell is disabled for a period of time, so that after the first period of time, the first cell may still be used as a candidate registration cell of the terminal device, and thus the registration range of the terminal device may be expanded.
In another optional implementation, the performing a target operation according to the first information and the processing policy may include:
under the condition that a second condition is met, closing the 5G capability of the terminal equipment;
wherein the second condition comprises: the processing policy includes turning off 5G capability of terminal devices registered to the first cell, and at least one of:
the available neighbor cell condition indicates that the terminal equipment does not have an available neighbor cell;
the communication condition indicates that the communication of the terminal equipment is abnormal.
In this embodiment, the first terminal may shut down the 5G capability of the terminal device registered in the first cell when the processing policy of the first cell includes shutting down the 5G capability of the terminal device registered in the first cell, and the terminal device is abnormal in communication in the first cell, and/or the terminal device shuts down the 5G capability of the terminal device and registers in the third cell when the first cell cannot search for an available neighboring cell; otherwise, camping on the first cell may continue. Therefore, the terminal equipment can be ensured to close the 5G capability only under the condition that the terminal equipment really has the requirement of closing the 5G capability, namely under the condition that the strategy of closing the 5G capability is suitable for the terminal equipment, so that the terminal equipment can be prevented from closing the 5G capability when the terminal equipment does not need to close the 5G capability, and the reliability of the communication processing of the terminal equipment can be improved.
It should be noted that, the embodiment of the present application does not limit the execution sequence of the following determination operations: determining whether a processing policy of a first cell includes closing a 5G capability of a terminal device registered to the first cell; determining whether the communication of the terminal equipment is abnormal; and determining whether the terminal equipment has an available adjacent cell.
In an alternative implementation manner, the terminal device may determine whether communication of the terminal device is abnormal after determining that the processing policy of the first cell includes closing the 5G capability of the terminal device registered to the first cell.
And determining whether the terminal equipment has an available adjacent cell or not under the condition that the communication of the terminal equipment is abnormal. And under the condition that the terminal equipment does not have an available adjacent cell, the communication quality of the shared area network is poor, the 5G capability can be closed, the first cell is escaped, and the terminal equipment is registered to the non-shared cell. Under the condition that the terminal equipment has the available adjacent cell, the terminal equipment can firstly escape from the first cell temporarily in a mode of forbidding the first cell and register the terminal equipment to other shared cells so as to solve the problem of communication abnormity.
And under the condition that the communication of the terminal equipment is normal, the terminal equipment can normally communicate in the first cell, and the terminal equipment can continue to reside in the first cell.
In the case of turning off the 5G capability, in one implementation, the terminal device may permanently turn off the 5G capability.
In another implementation, after the 5G capability of the terminal device is turned off, the method may further include:
and when the closing time of the 5G function of the terminal equipment reaches a second time, starting the 5G function of the terminal equipment, and reporting the 5G capability of the terminal equipment to the target cell.
In an alternative implementation manner, the terminal device may set a timer, and determine whether the closing time of the 5G function reaches the second time through the timer. In this manner, the first electronic device may start the timer at the same time as the off duration of the 5G function, set the duration of the timer to the second duration, restart the 5G capability when the timer is overtime, and report the 5G capability to the target cell.
In this implementation, the terminal device may restart the 5G capability after closing the 5G capability for a period of time, and report the 5G capability to the target cell, so that the target cell may configure its measurement shared cell based on the 5G capability of the terminal device, and register to the shared cell for 5G communication, thereby improving communication quality.
It should be noted that, the timer for determining whether the forbidden time duration of the first cell reaches the first time duration and the timer for determining whether the closing time duration of the 5G function reaches the second time duration may be the same timer or different timers, which may be determined specifically according to actual requirements, and the embodiment of the present application is not limited thereto.
In some embodiments, the obtaining the processing policy corresponding to the first cell may include:
receiving second information, wherein the second information comprises identification information of an abnormal cell and a processing strategy corresponding to the abnormal cell;
and acquiring a processing strategy corresponding to the first cell from the second information under the condition that the second information comprises the identification information of the first cell.
In a specific implementation, the second information may be sent by a server. In one implementation, the server may periodically send the second information; in another implementation manner, the server can send the second information based on the request of the terminal device; in another implementation manner, the server may send the second information when the terminal device is not connected to the 5G SCG.
In an embodiment of the present application, the server may be configured to: collecting and counting abnormal events of the registered cells sent by the terminal equipment, determining whether the cells are abnormal cells or not based on the number of the abnormal events of each cell in a certain time period, and further determining a processing strategy corresponding to the abnormal cells.
In an optional implementation manner, in a case that the number of exceptional events of the first cell is greater than a first threshold, the processing policy may include: disabling the first cell; in the case that the number of abnormal events of the first cell is greater than a second threshold, the processing policy may include: closing the 5G capability of the terminal equipment registered to the first cell; wherein the second threshold is greater than the first threshold.
When the number of the abnormal events of the first cell is greater than a first threshold, it is described that the first cell is abnormal, the first cell may be determined as an abnormal cell, and in order to improve communication fluency of a terminal device registered in the first cell, a processing policy may be added to the first cell: disabling the cell. In this way, the terminal device may disable the first cell to escape the first cell based on the processing policy.
When the number of the abnormal events of the first cell is greater than a second threshold, it indicates that the communication quality of the shared network area is not good, and in order to improve the communication fluency of the terminal device registered in the first cell, a processing policy may be added to the first cell: and closing the 5G capability of the terminal equipment registered to the first cell. In this way, the terminal device may turn off the 5G capability to escape the shared network area based on the processing policy.
The abnormal event of the cell sent by the terminal equipment can comprise at least one of the following events: the resource scheduling of the terminal equipment in the cell is abnormal, and the communication of the terminal equipment in the cell is abnormal.
In this embodiment, the processing policy corresponding to the first cell is sent to the terminal device by a server.

In this way, the processing policy corresponding to the first cell can be matched with the current situation of the first cell, so that the reference value of the processing policy corresponding to the first cell to the execution operation of the terminal device can be improved.
It should be noted that various alternative embodiments, implementation manners or implementations provided in the embodiments of the present application may be implemented in combination or independently without conflict with each other, and may be determined according to actual needs, which is not limited in the embodiments of the present application.
In order to facilitate understanding of the cell selection method provided in the foregoing embodiments, the cell selection method is described below with a specific scenario embodiment. Fig. 2 is a flowchart illustrating a scenario embodiment of a cell selection method according to an embodiment of the present application.
The scenario embodiment may specifically include the following steps:
In this case, the network may query for 5G capabilities and configure the terminal to register with the shared anchor cell more easily.
If yes, go to step 203; otherwise, the flow may end.
In specific implementation, the mobile station may determine whether to register the shared anchor cell according to the PLMN and the registered frequency point, for example: and if the PLMN mark of the first operator registers the frequency point cell belonging to the second operator, the PLMN mark is judged to be registered in the shared anchor point cell.
If yes, go to step 204, otherwise, end.
And the background big data system (namely the server) collects and counts the abnormal conditions of the shared anchor point cells.
If the abnormal number of the shared anchor point cell exceeds the threshold value Th1 (namely the first threshold value), the background big data adding strategy disables the cell;
if the abnormal number of the shared anchor point cell exceeds the threshold Th2 (i.e. the aforementioned second threshold), the background big data adding strategy is turned off by 5G.
If yes, go to step 205, otherwise go to step 208.
Namely, whether the data transmission has the uplink and downlink scheduling problem is judged, and the judging method comprises the following steps:
if the uplink data of the mobile station in the cell is lower than the thresholds Th _ Rx and Th _ Tx; and the delay of the TCP packet is greater than Th _ TCP _ delay, the resource scheduling exception can be judged.
That is, the mobile station determines that the nearby area can not search for the available neighboring area, if yes, the step 207 is proceeded, otherwise, the step 208 is proceeded.
The threshold N1 is a disable threshold set by the scheme, and may be adjusted according to practical situations, for example, may be set to 5 minutes.
That is, the mobile terminal determines whether the data transmission has obvious sensed abnormalities such as network disconnection and multiple times of blocking and breaking, if yes, the mobile terminal goes to step 209, otherwise, the mobile terminal does not execute the operation.
If yes, go to step 210, otherwise, end.
Further, the mobile station may report that the network does not support the 5G capability, so that the network redirects or switches the terminal to the non-anchor cell. The threshold N2 is a 5G capability closing threshold set by the scheme, and may be adjusted according to actual conditions, for example, may be set to 5 minutes.
In step 211, the mobile station checks whether the timer has expired.
I.e., whether N2 minutes has elapsed since closing 5G, step 212 is performed if the timer has timed out, otherwise no action is performed.
In this scenario embodiment, the server may identify the abnormal shared anchor cell, and make a specific communication recovery policy for the abnormal shared anchor cell. Under the condition of residing on the abnormal shared anchor point cell, the abnormal shared anchor point cell can be quickly escaped based on a communication recovery strategy, and the communication stability of the mobile station is improved.
