[0037] In all examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not as limiting. Therefore, other examples of the exemplary embodiments may have different values.

[0038] It should be noted that like reference numerals and letters refer to similar items in the following figures, and therefore, once an item is defined in one figure, it need not be further discussed in subsequent figures.

[0039] Figure 1 FIG. 2 shows a schematic flow chart of a reselection method according to some embodiments of the present invention. Figure 1 As shown, the reselection method of this embodiment includes steps S102 to S108.

[0040] In step S102, the base station shared by the first operator and the second operator obtains the load status of the cell at the frequency point where the terminal currently resides.

[0041] The co-built and shared base station in this embodiment provides multiple frequency points, which are shared by multiple operators, and without considering the load conditions, the frequency-specific priorities of these frequency points are the same.

[0042] In some embodiments, the base station is a 5G SA co-built and shared base station, and the terminal is an NR (New Radio) SA terminal.

[0043] In some embodiments, the base station determines the load condition of the frequency point according to a preset threshold.

[0044] In step S104, the terminal receives a broadcast message sent by the base station, wherein the broadcast message includes load information corresponding to the load condition of the cell at the frequency point where the terminal is currently stationed.

[0045] In some embodiments, the broadcast message is a MIB (Master Information Block) message in the NR broadcast message. Thus, the existing broadcast message can be used to indicate the load status of the frequency point to the terminal, which has a small change in the protocol, standard and equipment and has higher compatibility.

[0046] In some embodiments, the load information is located in the spare bits of the MIB message. Currently, the protocol stipulates that the spare bits are used for extended functions, thereby further reducing the amount of changes to the standard and being compatible with previous protocols and devices.

[0047] In the related art, the structure of the MIB message is as follows.

[0048]

[0049]

[0050] In the above format, the bit corresponding to "spare" is the spare bit. Some embodiments of the present invention redefine the meaning of this bit to indicate the load of the cell where the terminal currently resides. An example of the redefined message structure is as follows.

[0051]

[0052] In this example, "loadStatus" is used to represent the load status field, and this field is an enumeration type, including two values ​​of "heavy" and "light". When loadStatus = heavy, it means that the load of the cell where the terminal is currently residing at the frequency point is heavier than the preset level (for example, the load value is higher than the preset value); when loadStatus = light, it means that the load of the cell where the terminal is currently residing at the frequency point is lighter than the preset level (for example, the load value is lower than the preset value).

[0053] In step S106, the terminal adjusts the load priority information of the current resident frequency point according to the load information.

[0054] In some embodiments, after powering on or restarting, the terminal initializes the load priority information of each available frequency point provided by the base station so that the load priority of each available frequency point is the same. That is, without considering the load, the priority of each frequency point is the same.

[0055] In some embodiments, the terminal obtains the load priority value corresponding to each frequency point under the base station; if the load information indicates that the load of the cell at the frequency point where the terminal is currently stationed is heavier than a preset level, the terminal lowers the load priority value of the frequency point; if the load information indicates that the load of the cell at the frequency point where the terminal is currently stationed is lighter than a preset level, the terminal increases the load priority value of the frequency point.

[0056] For example, assume that the initial value of the load priority of each frequency point provided by the base station is S0, and the user currently resides at frequency point A. When the load information indicates that the load of the cell at frequency point A is heavier than the preset level, the value of the load priority of frequency point A after adjustment is S=S0-a, where a represents the adjustment amplitude and is a positive number; when the load information indicates that the load of the cell at frequency point A is lighter than the preset level, the value of the load priority of frequency point A after adjustment is S=S0+a.

[0057] In step S108, when the frequency point where the terminal currently resides is different from the frequency point available to the terminal and having the highest load priority, the terminal reselects the frequency point with the highest load priority.

[0058] For example, the terminal currently resides on frequency point A provided by the first operator. However, after the priority adjustment in step S106, it is found that frequency point B provided by the second operator with the same coverage has a higher priority, which means that the cell of frequency point B is currently more idle, so the terminal reselects to frequency point B.

[0059] Through the above embodiments, the terminal can adjust the load priority according to the load weight of each frequency point based on the instruction of the base station, so that the terminal can adjust the reselection strategy and reselect to another idle frequency point with the same coverage. Therefore, the terminal can initiate an RRC connection at any time on the idle frequency point, thereby reducing the monitoring, waiting and switching operations related to load balancing on the terminal side, reducing the access delay, improving the user experience under the shared carrier of the co-built and shared base station, and improving the utilization rate of shared network resources.

[0060] In some embodiments, the base station may add a switch to send load information to the terminal to enable or disable the process of reselecting a solution based on the load. Figure 2 An embodiment of a base station side control method is described.

[0061] Figure 2 FIG. 2 is a flow chart showing a base station side control method according to some embodiments of the present invention. Figure 2 As shown, the base station side control method of this embodiment includes steps S202 to S218.

[0062] In step S202, a shared carrier base station jointly built and shared by multiple operators is powered on or restarted.

[0063] In step S204, the base station performs initialization and parameter configuration.

[0064] In step S206, the base station determines whether it is currently in a load-based reselection mode. If not, step S208 is executed; if yes, step S210 is executed.

[0065] In step S208, the switching-based load balancing process in the related art is entered.

[0066] In step S210, a load-based reselection process is entered.

[0067] In step S212, the base station determines the load of the cell where the terminal currently resides. If the load of the cell where the terminal currently resides is heavier than a preset level, step S214 is executed; if the load of the cell where the terminal currently resides is lighter than a preset level, step S216 is executed.

[0068] In step S214, in the MIB message, loadStatus representing load information is set to heavy.

[0069] In step S216, in the MIB message, loadStatus representing load information is set to light.

[0070] In step S218, the base station periodically broadcasts MIB messages.

[0071] Steps S206 to S218 may be executed in a loop.

[0072] The above-mentioned embodiments support both the original load balancing strategy and the strategy of adjusting reselection based on load information proposed by the present invention. The shared carrier base station can notify all terminals in the cell of the current frequency of the load information by periodically broadcasting a MIB message in a new format including the load weight information of the current frequency cell. After receiving the MIB message in the new format, the terminal adjusts the reselection strategy according to the cell load situation of the current frequency to reselect to another idle cell with the same coverage. Thereby, the access delay is reduced, the user experience under the shared carrier is improved, and the utilization rate of shared network resources is improved.

[0073] In some embodiments, the terminal may also add a switch for determining whether to reselect based on load conditions, so as to enable or disable the process of reselecting a solution based on load. Figure 3 An embodiment of a terminal-side reselection method is described.

[0074] Figure 3 FIG. 2 shows a schematic flow chart of a terminal side reselection method according to some embodiments of the present invention. Figure 3 As shown, the terminal-side reselection method of this embodiment includes steps S302 to S318.

[0075] In step S302, the terminal performs a power-on or restart process. In some embodiments, the terminal is a SANR terminal.

[0076] In step S304, the terminal performs initialization and parameter configuration, and initializes the value of the load priority of each available frequency point to S0.

[0077] In step S306, the terminal determines whether it is currently in a mode of reselection based on load conditions. If not, step S308 is executed; if yes, step S310 is executed.

[0078] In step S308, the MIB message broadcast by the base station is parsed in a standard MIB format.

[0079] In step S310, the MIB message broadcast by the base station is parsed using the parsing method of the new MIB format.

[0080] In step S312, the terminal determines whether the value of the loadStatus field representing the load information in the MIB message is heavy or light. If it is heavy, execute step S314; if it is light, execute step S316.

[0081] In step S314, the value of the load priority of the frequency point where the terminal currently resides is set to S=S0-a, where a represents the adjustment amplitude and is a positive number.

[0082] In step S316, the value of the load priority of the frequency point where the terminal is currently residing is set to S=S0+a.

[0083] In step S318, when the frequency point where the terminal is currently residing is different from the frequency point available to the terminal and having the highest load priority, the terminal reselects the frequency point with the highest load priority.

[0084] Part or all of the above steps may be executed in a loop.

[0085] The above embodiment supports both the original load balancing strategy and the strategy of adjusting reselection based on load information proposed by the present invention. The terminal can periodically receive a MIB message in a new format including the load information of the cell at the current resident frequency point. After parsing the MIB message in the new format, the terminal adjusts the reselection strategy according to the load situation of the cell at the current resident frequency point to reselect to another relatively idle frequency point with the same coverage. Thus, the access delay is reduced and the user experience under the shared carrier of the co-built and shared base station is improved.

[0086] When applied to SA co-construction and sharing base stations and the terminals covered by them, the above embodiments can greatly improve the reliability and completeness of the SA co-construction and sharing technical solution, shorten the network construction cycle, and reduce the network construction, operation and maintenance, and business development costs. In addition, the above embodiments have fewer modifications to the network side and the terminal side, and the implementation complexity is low, so it is easy to implement the system and promote the solution.
