Description

Technical Field

[0001] This application relates to the field of communication technology, and in particular to an evaluation method and related equipment for adding and changing conditional auxiliary base stations. Background Technology

[0002] In 5G (5th Generation Mobile Communication Technology) systems, to improve terminal service quality, terminals are allowed to connect to two base stations for data transmission and reception. The base station responsible for terminal management and control is called the primary base station, and the base station assisting the terminal in data transmission and reception is called the secondary base station. In order to reduce signaling overhead and improve the efficiency of adding and changing secondary base stations, a conditional secondary base station addition and change mechanism has been introduced. This mechanism allows conditional configuration at the primary base station, and the terminal can update or add secondary base stations on its own based on the measurement and evaluation results of the conditional configuration.

[0003] However, the current mechanism for adding and changing conditional secondary base stations only allows the terminal to perform the process once. Without the primary base station reconfiguring and sending the conditions back to the terminal, the terminal will not execute its own secondary base station update process. If the terminal needs to continue the secondary base station change process, the primary base station must reconfigure the conditional secondary base station addition and change, which is complex and inefficient.

Obviously, the drawings in the following description are only some embodiments of the present application, and other drawings can be obtained by those skilled in the art without creative effort.

[0022] Figure 1 is a flowchart of a connection switching management method according to an embodiment of the present application. DETAILED DESCRIPTION

[0023] Reference Signs List Figure 1The embodiment of the present application provides a connection switching management method, which can be applied to a terminal, for example, a mobile phone, a cordless phone, a smart wearable device or the like, and the terminal has established a communication connection with a main base station in a communication system, wherein the communication system further comprises a neighboring base station of the main base station, and the method comprises the following steps.

[0024] S10: receiving first broadcast information sent by the main base station, wherein the first broadcast information comprises a first conditional secondary base station addition change control parameter. The first conditional secondary base station addition change control parameter comprises the following parameters: Tcpa, representing an addition change statistical period, Ncpa_M, representing a medium-level addition change frequency threshold value, and Ncpa_H, representing a high-level addition change frequency threshold value.

[0025] S11: saving the first conditional secondary base station addition change control parameter.

[0026] In one embodiment, after the terminal establishes the communication connection with the main base station, the main base station sends a broadcast message (i.e. the first broadcast information) to the terminal, and the broadcast message comprises a conditional secondary base station addition change control parameter (i.e. the first conditional secondary base station addition change control parameter). Exemplarily, the first conditional secondary base station addition change control parameter comprises the parameters shown in Table 1.

[0027] Table 1

[0028]

[0029] Further, after the terminal receives the first broadcast information, the terminal stores the first conditional secondary base station addition change control parameter in the first broadcast information, and sets an initial value of a counter N as 0. The value of N can represent the number of times of secondary base station change.

[0030] S12: measuring the neighboring base stations, and determining a target secondary base station from the neighboring base stations based on the measurement results.

[0031] As a feasible implementation, the first conditional secondary base station addition change control parameter further comprises a parameter: Time to trigger, representing a time T1 of triggering of a secondary base station evaluation condition. The secondary base station evaluation condition comprises a first secondary base station evaluation condition and a second secondary base station evaluation condition. The measurement results comprise a cell signal measurement value of each of the neighboring base stations, and the determining of the target secondary base station from the neighboring base stations based on the measurement results comprises the following steps.

[0032] If the cell signal measurement value of any one of the neighboring base stations meets a first secondary base station evaluation condition and continuously meets the first secondary base station evaluation condition within a first time length when the terminal is not currently connected to any secondary base station, the any one of the neighboring base stations is determined as a target secondary base station; the first secondary base station evaluation condition is: Mn+On-H×factor>Th1;

[0033] Wherein, Mn represents the measured cell signal measurement value of the neighboring base station, On represents the calculated compensation value of the neighboring base station, H represents a hysteresis value, factor represents a hysteresis influence factor, and TH1 is a threshold value corresponding to the first secondary base station evaluation condition; the first time length is T1×factor. Exemplarily, the default value of factor can be 1;

[0034] Or, if the cell signal measurement value of any one of the neighboring base stations meets a second secondary base station evaluation condition and continuously meets the second secondary base station evaluation condition within a first time length when the terminal is currently connected to a secondary base station, the any one of the neighboring base stations is determined as a target secondary base station; the second secondary base station evaluation condition is: (Mn+On)-(Ms+Os)-H×factor>Th2;

[0035] Wherein, Mn represents the measured cell signal measurement value of the neighboring base station, On represents the calculated compensation value of the neighboring base station, H represents a hysteresis value, factor represents a hysteresis influence factor, TH2 is a threshold value corresponding to the second secondary base station evaluation condition, Ms represents the cell signal measurement value of the currently connected secondary base station, and Os represents the calculated compensation value of the currently connected secondary base station; the first time length is T1×factor.

[0036] It can be understood that the above On, H and Os can be pre-set according to experimental measurement data, and the specific values are not limited. Th1 and Th2 are determined according to the values of the parameters Addition Evaluate condition and Change evaluate condition in the first condition secondary base station addition change control parameter.

[0037] S13: performing synchronization and random access processes with the target secondary base station, setting the value of a counter N according to the information of the target secondary base station after the execution is completed, setting the value of a first timer as the value of a parameter Tcpca, and starting the first timer to count down.

[0038] As a feasible way, the above setting the value of the counter N according to the information of the target secondary base station can include:

[0039] If the operating frequency of the target secondary base station belongs to the first frequency band, and the information of the target secondary base station satisfies the first secondary base station counting condition, the value of the counter N is accumulated by a first preset value; wherein the first frequency band is a frequency band less than or equal to 6GHZ, and the first secondary base station counting condition is that the target secondary base station and the currently connected secondary base station use the same access technology, or the target secondary base station is a newly added secondary base station.

[0040] For example, the first preset value can be 1, and when the operating frequency of the target secondary base station belongs to the first frequency band, and the information of the target secondary base station satisfies the first secondary base station counting condition, the value of the counter N is N+1. For example, assuming that the current value of the counter N is 0 (i.e. N=0), when the terminal detects that the operating frequency of the target secondary base station belongs to the first frequency band, and the information of the target secondary base station satisfies the first secondary base station counting condition, the value of the counter N is updated to 0+1=1.

[0041] Alternatively, if the operating frequency of the target secondary base station belongs to the millimeter wave frequency band, and the information of the target secondary base station satisfies the first secondary base station counting condition, the value of the counter N is set to N×weight_FR2, and the weight_FR2 is set to a value less than 1. Here, the weight_FR2 is set to a value less than 1, which can make the terminal reduce the increase of the counter when operating in the base station of the millimeter wave frequency band with smaller coverage, so that a lower frequency impact factor can be applied in the secondary base station evaluation condition, or a new impact factor is not introduced, so that the change condition of the secondary base station is not improved.

[0042] Alternatively, if the operating frequency of the target secondary base station belongs to the first frequency band, and the target secondary base station and the currently connected secondary base station use different access technologies (for example, changing from an LTE secondary base station to an NR secondary base station, or changing from an NR secondary base station to an LTE secondary base station), the value of the counter N is set to N+weight_Inter-RAT; wherein the weight_Inter-RAT is a value greater than 1, which can make the terminal increase the value of the counter after moving to the base station of different access technologies, so as to use a higher frequency impact factor to improve the change condition and increase the time trigger time, thereby reducing the number of changes and reducing the delay introduced by the core network node transformation due to the change between base stations of different access technologies.

[0043] Alternatively, if the operating frequency of the target secondary base station belongs to the millimeter wave frequency band, and the target secondary base station and the currently connected secondary base station use different access technologies, the value of the counter N is set to N+weight_FR2×weight_Inter-RAT.

[0044] S14: resetting and restarting the first timer at the end of the first timer countdown, and continuously performing evaluation of conditional secondary base station addition change according to the value of the counter N, the value of Ncpca_M and the value of Ncpca_H.

[0045] As a feasible implementation, the first conditional secondary base station addition change control parameter further comprises the following parameters: FHcpca_M, representing a medium level addition change frequency impact factor, and FHcpca_H, representing a high level addition change frequency impact factor; and the evaluation of conditional secondary base station addition change according to the value of the counter N, the value of Ncpca_M and the value of Ncpca_H comprises:

[0046] If the value of the counter N is less than Ncpca_M, the current first conditional secondary base station addition change control parameter is maintained for the evaluation of conditional secondary base station addition change;

[0047] If Ncpca_M≤ the value of the counter N < Ncpca_H, the value of factor in the current secondary base station evaluation condition is set to factor x the value of parameter FHcpca_M, and the new factor value is used for the evaluation of conditional secondary base station addition change;

[0048] If the value of the counter N is greater than or equal to Ncpca_H, the value of factor in the current secondary base station evaluation condition is set to factor x the value of parameter FHcpca_H, and the new factor value is used for the evaluation of conditional secondary base station addition change. The value of parameter FHcpca_H is greater than the value of parameter FHcpca_M, and the values of the two parameters are both greater than 1.

[0049] In this way, the evaluation condition can be dynamically adjusted according to the state of the motion of the terminal, such as the change of addition change frequency caused by the moving speed or the switching between different access technology networks, so that the terminal can reduce the number of changes when changing the secondary base station by itself, thereby reducing the signaling of the terminal and saving power consumption.

[0050] In one embodiment, the above method further comprises the following steps:

[0051] S15: if the primary base station connected by the terminal is switched to a target primary base station during the movement of the terminal, reading second broadcast information of the target primary base station, the second broadcast information comprising a second conditional secondary base station addition change control parameter.

[0052] S16: If the second conditional secondary base station addition change control parameter is the same as the first conditional secondary base station addition change control parameter currently used by the terminal, the first conditional secondary base station addition change control parameter is continued to be used to perform the evaluation of the conditional secondary base station addition change.

[0053] S17: If the second conditional secondary base station addition change control parameter is not the same as the first conditional secondary base station addition change control parameter currently used by the terminal, the evaluation of the conditional secondary base station addition change is performed according to the second conditional secondary base station addition change control parameter.

[0054] As a feasible implementation, the evaluation of the conditional secondary base station addition change according to the second conditional secondary base station addition change control parameter in step S17 can include the following modes:

[0055] Mode 1: The first timer is stopped when the first timer countdown is not ended, the value of the counter N is reset to 0, the value of the factor is reset to a default value, the value of the first timer is set to the value of Tcpa in the second conditional secondary base station addition change control parameter, the first timer is started and the evaluation is performed according to the second conditional secondary base station addition change control parameter;

[0056] Mode 2: The first timer is stopped when the first timer countdown is not ended, the value of the counter N is reset to 0, the value of the factor is kept unchanged, the value of the first timer is set to the value of Tcpa in the second conditional secondary base station addition change control parameter, the first timer is started and the evaluation is performed according to the second conditional secondary base station addition change control parameter;

[0057] Mode 3: The first timer is continued to run when the first timer countdown is not ended, the values of the counter N and the factor are kept unchanged, and the evaluation is performed using the first conditional secondary base station addition change control parameter currently used; when the first timer countdown is ended, the value of the first timer is set to the value of Tcpa in the second conditional secondary base station addition change control parameter, the first timer is started and the evaluation is performed according to the second conditional secondary base station addition change control parameter;

[0058] Mode 4: The first timer is continued to run when the first timer countdown is not ended, the values of the counter N and the factor are kept unchanged, and the evaluation is performed using the second conditional secondary base station addition change control parameter; when the first timer countdown is ended, the value of the first timer is set to the value of Tcpa in the second conditional secondary base station addition change control parameter, the first timer is started and the evaluation is performed according to the second conditional secondary base station addition change control parameter.

[0059] As a feasible implementation, the terminal can acquire the value of the factor, the value of the parameter FHcpca_H, the value of the first timer and the value of Ncpca_M, and if the value of the factor is less than the value of the parameter FHcpca_H and the value of the first timer is less than 1 / 2*Ncpca_M, the evaluation of conditional secondary base station addition or change is performed by the above-mentioned mode 1.

[0060] Alternatively, if the value of the factor is greater than the value of the parameter FHcpca_H and the value of the first timer is less than 1 / 2*Ncpca_M, the evaluation of conditional secondary base station addition or change is performed by the above-mentioned mode 2. If the value of the factor is less than the value of the parameter FHcpca_H and the value of the first timer is greater than or equal to 1 / 2*Ncpca_M, the evaluation of conditional secondary base station addition or change is performed by the above-mentioned mode 3. If the value of the factor is greater than the value of the parameter FHcpca_H and the value of the first timer is greater than or equal to 1 / 2*Ncpca_M, the evaluation of conditional secondary base station addition or change is performed by the above-mentioned mode 4.

[0061] In the embodiments of the present application, the above-mentioned mode can make the terminal still ensure the effective execution of the evaluation process when the primary base station is switched, further improve the adaptive ability of the terminal and guarantee the service quality of the terminal.

[0062] It can be understood that, in the present application, the so-called addition can be understood as that the current terminal is not connected to any secondary base station and a new secondary base station needs to be added, and this case is the addition of the secondary base station; the so-called change can be understood as that the current terminal is connected to a secondary base station and a new secondary base station needs to be switched, and this case is the change of the secondary base station.
