Description

Technical Field

[0001] This application relates to the field of communication technology, and in particular to a method and apparatus for reselecting priority configuration. Background Technology

[0002] For operators sharing the network, although the network is completely shared, operators still prefer their users to stay on their own frequency bands. For example, if a first operator in a city is responsible for building a 200MHz network in the 3.4GHz-3.6GHz frequency band, then both the first and second operators would prefer their users to stay on their respective 100MHz frequency band cell networks. This necessitates that the wireless network can be configured with different frequency priorities based on the different operators' users.

[0003] In existing technologies, base stations configure different frequency priorities and notify terminals via system broadcast messages. Terminals then select the frequency with the highest priority based on signal strength for camping and access, according to the frequency priority in the broadcast. In co-construction and sharing scenarios, different operators may employ different strategies for selecting the same frequency, thus requiring base stations to be able to configure frequency priorities based on user settings. Currently, frequency priority configuration requires manual intervention by maintenance personnel.

[0004] However, due to the complexity of frequency priority in co-construction and sharing scenarios, manual configuration is inefficient and prone to errors, resulting in low system reliability. Summary of the Invention

[0020] Optionally, before sending the target message to the target terminal, the method further includes:

[0021] If the priority of the target frequency point among all frequency points corresponding to the target terminal is greater than or equal to the priority of the frequency point of the different system, and if the target frequency band used by the target operator is a preset frequency band, and the priority of the target high frequency point is greater than or equal to the priority of the target low frequency point, then the minimum value of the priority of the target low frequency point minus the fourth preset value is configured as the priority of the target high frequency point of the target terminal.

Obviously, the drawings described below are some embodiments of this application. For those skilled in the art, other drawings can be obtained based on these drawings without creative effort.

[0053] Figure 5 This is a schematic diagram of the reselection priority configuration device provided in the embodiments of this application. Detailed Implementation

[0054] During the rapid development of the 5G network, operators face the challenges of rapid 5G network deployment, limited 5G frequency bands (with different operators having very limited 5G frequency bands), and a small number of early 5G users. Furthermore, the large-scale network construction expenditures of operators will take a long time to generate returns. For these reasons, operators are considering jointly building and sharing 5G networks, which can achieve advantages such as better utilization of 5G frequency bands and sharing of 5G network construction costs. For example, of the 200MHz spectrum resources in the 3.4GHz-3.6GHz band, 100MHz of the 3.4GHz-3.5GHz band is allocated to the second operator, and 100MHz of the 3.5GHz-3.6GHz band is allocated to the first operator. If the first and second operators co-build and share the spectrum, then the 5G users of both operators can use these 200MHz of spectrum resources. Currently, 160MHz of spectrum resources in the 2.6GHz band are allocated to the third operator, and 30MHz of spectrum resources in the 700MHz band are allocated to the fourth operator. If the third and fourth operators co-build and share the spectrum, then the users of both operators can use 190MHz of spectrum resources in the 2.6GHz and 700MHz bands.

[0055] For operators sharing the network, although the network is completely shared, operators still hope that their users will stay on their own frequency band resources. For example, if a city's first operator is responsible for building a 200M network on the 3.4G-3.6G frequency band, then the first operator and the second operator hope that their users can stay on their respective 100M frequency band cell networks. This requires the wireless network to be able to configure different frequency priority based on different operators' users.

[0056] In non-co-construction and sharing scenarios, network-side equipment (e.g., base stations) is configured with different frequency priorities, which are notified to the terminal in system broadcast messages. The terminal selects the frequency with the higher priority based on signal strength for camping and access, according to the frequency priority in the broadcast. For intra-frequency reselection, intra-frequency reselection is initiated when the minimum received level of the signal strength reduction area measured by the terminal is less than 0; reselection is triggered when the signal strength of a neighboring intra-frequency cell is greater than the minimum received level of the cell. For inter-frequency high-priority reselection, the terminal continuously measures the frequency and triggers reselection when the high-priority reselection threshold is met. For inter-frequency low-priority frequencies, if no high-priority frequency meets the threshold, measurement is initiated when the signal strength of the serving cell is lower than a certain threshold, and reselection is triggered when the signal strength of a neighboring cell is higher than a certain threshold. For inter-system high-priority frequencies, the terminal continuously measures and triggers reselection when the signal strength of a neighboring inter-system cell meets a threshold; for inter-system low-priority frequencies, measurement is initiated when the signal strength of the serving cell is lower than a certain threshold, and reselection is triggered when the signal strength of a neighboring inter-system cell is higher than the threshold.

[0057] However, in the context of co-construction and sharing, different operators have different strategies for selecting user frequency points for the same frequency point, so base stations need to be able to prioritize user-configured frequency points.

[0058] In existing protocols, user-specific frequency priority can be carried in the Radio Resource Control (RRC) release message. However, manually configuring priorities for different users and different frequencies is cumbersome, prone to errors, and inconvenient for system maintenance, resulting in low system reliability.

[0059] To address the aforementioned technical problems, embodiments of the present invention can, through simple configuration, allow network-side devices to automatically determine the priority of serving cell frequency points, inter-frequency points, and inter-system frequency points based on the terminal's operator, and inform the terminal through target messages. This achieves the effect that terminals of shared operator users preferentially select the network of their own operator in idle or inactive states.

[0060] Figure 1 This is a flowchart illustrating the priority configuration method for reselection provided in an embodiment of this application, as shown below. Figure 1 As shown in the figure, this application provides a method for reselecting priority configuration, the execution subject of which can be a network-side device, such as a base station, etc., and the method includes:

[0061] Step 101: Determine the priority of all frequency points corresponding to the target terminal based on the target operator to which the target user belongs.

[0062] Specifically, in this embodiment of the application, the priority of all frequency points corresponding to the terminal is first determined based on the operator to which the user to which the terminal belongs.

[0063] Among them, all frequency points corresponding to the terminal include at least one of the following: the frequency point of the current serving cell, the frequency point of the different frequency, and the frequency point of the different system.

[0064] For example, if the user's operator is the same as the operator of the frequency point of the terminal's current serving cell, the priority of the frequency point of the terminal's current serving cell is determined to be equal to the priority of that frequency point in the broadcast message.

[0065] For example, if the user's operator is different from the operator of the frequency point of the terminal's current serving cell, the priority of the frequency point of the terminal's current serving cell is determined to be equal to the priority of that frequency point in the broadcast message minus a first preset value. This first preset value can be configured according to the actual application scenario, and its value can be, but is not limited to: 0.2, 0.4, 0.6, 0.8, or 1.

[0066] For example, if the user's operator is the same as the operator of the frequency point supported by the terminal, the priority of the frequency point supported by the terminal is determined to be equal to the priority of that frequency point in the broadcast message.

[0067] For example, if the user's carrier is different from the carrier of the frequency point supported by the terminal, the priority of the frequency point supported by the terminal is determined to be equal to the priority of that frequency point in the broadcast message minus a second preset value. This second preset value can be configured according to the actual application scenario, and its value can be, but is not limited to: 0.2, 0.4, 0.6, 0.8, 1.

[0068] Step 102: Send a target message to the target terminal, the target message containing the priority of all frequency points corresponding to the target terminal.

[0069] Specifically, after determining the priorities of all frequency points of the terminal, the network-side device instructs the terminal through a target message. The target message sent by the network-side device to the terminal contains the priorities of all frequency points corresponding to the terminal.

[0070] The target message is a non-broadcast message and may include, but is not limited to, RRC release messages, downlink control information (DCI), and RRC connection reconfiguration messages.

[0071] The reselection priority configuration method provided in this application determines the priority of all frequency points corresponding to the terminal based on the operator to which the user belongs, thereby realizing automatic configuration of reselection priority and improving reliability.

[0072] Optionally, the priority of all frequency points corresponding to the target terminal is determined based on the target operator to which the target user belongs, including at least one of the following:

[0073] If the target operator and the operator to which the first frequency point belongs are the same, the priority of the first frequency point of the target terminal is determined to be equal to the priority of the first frequency point in the broadcast message.

[0074] If the target operator and the operator to which the first frequency point belong are different, the priority of the first frequency point of the target terminal is determined to be equal to the priority of the first frequency point in the broadcast message minus the first preset value. The first frequency point is the frequency point of the current serving cell of the target terminal.

[0075] When the target operator and the operator to which the second frequency point belong are the same, the priority of the second frequency point of the target terminal is determined to be equal to the priority of the second frequency point in the broadcast message.

[0076] When the target operator and the operator of the second frequency point are different, the priority of the second frequency point of the target terminal is determined to be equal to the priority of the second frequency point in the broadcast message minus the second preset value. The second frequency point is an inter-frequency point supported by the target terminal.

[0077] If the target operator and the operator to which the third frequency point belongs are the same, or if the target operator and the operator to which the third frequency point belongs are different, and the target frequency band used by the target operator is a preset frequency band, the priority of the third frequency point of the target terminal is determined to be equal to the priority of the third frequency point in the broadcast message.

[0078] If the target operator and the third frequency point belong to different operators, and the target operator uses a non-preset frequency band, the priority of not configuring the third frequency point of the target terminal is determined. The third frequency point is a cross-system frequency point supported by the target terminal.

[0079] For example, Figure 2 This is one of the logical flow diagrams of the reselection priority configuration provided in the embodiments of this application. Figure 2 Taking the target frequency band as the 5G frequency band and the preset frequency point as the 700M frequency band as an example, the explanation is as follows: Figure 2 As shown, determining the priority of all frequency points of the terminal includes the following steps:

[0080] Step 1: Start, the terminal is connected to the (5G) base station and is in a connected state.

[0081] Step 2: When the base station detects that the terminal has not had any service for a period of time, it prepares to release the liveness detection (User Inactive, UI) or other air interface release triggered by signaling processes, including but not limited to: context release triggered by the core network, release during redirection, etc.

[0082] Step 3: Determine whether the base station co-construction and sharing switch is turned on, which involves two scenarios:

[0083] (1) If the co-construction and sharing switch is turned on, proceed to step four.

[0084] (2) If the co-construction and sharing switch is closed, proceed to step thirteen.

[0085] Step 4: Determine whether the priority switch for dedicated frequency reselection is turned on on the base station. There are two possibilities:

[0086] (1) If the priority switch for reselecting the dedicated frequency point is turned on, then proceed to step five.

[0087] (2) If the priority switch for reselecting the dedicated frequency is turned off, proceed to step thirteen.

[0088] Step 5: The base station confirms the operator to which the current user belongs. The base station obtains the user's public land mobile network (PLMN) information from the current user's context, and then obtains the operator information to which the user belongs based on the operator identifier (ID) configured in the PLMN, for example, operator ID1.

[0089] Step Six: Determine whether the operator of the frequency point of the current serving cell is consistent with the operator of the user corresponding to the terminal. There are two cases:

[0090] (1) If the operator of the frequency point of the current serving cell is the same as the operator of the user corresponding to the terminal, then proceed to step nine.

[0091] (2) If the operator of the frequency point of the current serving cell is different from the operator of the user corresponding to the terminal, then proceed to step ten.

[0092] The method for determining the operator to which the frequency point of a serving cell belongs is as follows: the base station matches the frequency point information configured in the cell with the spectrum resources allocated to the operator for different frequency bands.

[0093] For example, if operator ID1 is matched, it is assumed that the operator to which the frequency point belongs is ID1. Then, the operator to which the frequency point of the serving cell belongs is compared with the operator to which the user to which the terminal belongs. If the operator IDs are the same, they are considered to be consistent; otherwise, they are considered to be inconsistent.

[0094] Step 7: Determine whether the operator of the different frequency point is the same as the operator of the user corresponding to the terminal. There are two cases:

[0095] (1) If the operator of the different frequency point is the same as the operator of the user corresponding to the terminal, then proceed to step nine.

[0096] (2) If the operator of the different frequency point is different from the operator of the user corresponding to the terminal, then proceed to step ten.

[0097] The method for determining the operator to which a frequency point belongs is as follows: the base station matches the frequency information configured in the frequency point table with the spectrum resources allocated to the operator for different frequency bands.

[0098] For example, if operator ID1 is matched, it is assumed that the operator to which the frequency point belongs is ID1. Then, the operator to which the frequency point of the serving cell belongs is compared with the operator to which the user to which the terminal belongs. If the operator IDs are the same, they are considered to be consistent; otherwise, they are considered to be inconsistent.

[0099] It should be noted that there may be multiple different frequency points in the base station configuration, and step seven needs to be performed for each different frequency point.

[0100] Step 8: Determine whether the operator of the different system frequency point (mainly 4G frequency point) is consistent with the operator of the user corresponding to the terminal. There are two cases:

[0101] (1) If the operator of the frequency point of the different system is the same as the operator of the user corresponding to the terminal, then proceed to step nine.

[0102] (2) If the operator of the frequency point of the different system is different from the operator of the user corresponding to the terminal, then proceed to step eleven.

[0103] The method for determining the operator to which a frequency point belongs in a different system is as follows: the base station matches the frequency point information of the different system configured in the frequency point table with the spectrum resources allocated to the operator for different frequency bands.

[0104] For example, if operator ID1 is matched, it is assumed that the operator to which the frequency point belongs is ID1. Then, the operator to which the frequency point of the serving cell belongs is compared with the operator to which the user to which the terminal belongs. If the operator IDs are the same, they are considered to be consistent; otherwise, they are considered to be inconsistent.

[0105] It should be noted that there may be multiple different system frequency points in the base station configuration, and step eight needs to be performed for each different system frequency point.

[0106] Step 9: Configure the dedicated frequency point priority as the terminal-level priority using the reselection priority of the broadcast message. This dedicated frequency point priority refers to the terminal-level priority, meaning that different terminals need to be configured separately.

[0107] Step 10: Configure the terminal-specific frequency priority by subtracting the pre-configured offset 'a' from the reselection priority of the frequency point in the broadcast message. The value of 'a' can be, but is not limited to, 0.2, 0.4, 0.6, 0.8, or 1.

[0108] Step 11: Determine if the user's carrier is a fourth-party carrier, which involves two scenarios:

[0109] (1) If the user is a fourth operator user, then proceed to step nine.

[0110] (2) If the user is not a user of the fourth operator, then proceed to step 12.

[0111] The base station obtains the user's PLMN information from the current user's context. Based on the operator ID configured in the PLMN, it can obtain the operator information to which the user belongs, and then confirm the operator attribute based on the operator ID.

[0112] It can generally be configured as follows: Carrier ID1 corresponds to the first carrier, Carrier ID2 corresponds to the second carrier, Carrier ID3 corresponds to the third carrier, and Carrier ID4 corresponds to the fourth carrier.

[0113] Step 12: Do not configure the reselection priority for this frequency point.

[0114] For users who are not affiliated with the fourth operator, each system has its own assigned frequency points. Therefore, if the user's operator and the operator of the assigned frequency point are different, the assigned frequency point of the other system will not be configured. However, for users of the fourth operator, since they do not have their own assigned frequency points, they need to use the frequency points of other operators.

[0115] Step 13: The base station obtains all frequency points and priorities corresponding to the terminal, and determines the specific values ​​of each frequency point in the RRC release message.

[0116] Step Fourteen: Send an RRC release message to the terminal, without carrying the terminal-specific frequency reselection priority.

[0117] Step 15: End, delete the user context.

[0118] The reselection priority configuration method provided in this application determines the reselection priority of the current serving cell frequency point, inter-frequency point, and inter-system frequency point based on the operator to which the user belongs, thereby realizing automatic configuration of reselection priority and further improving reliability.

[0119] Optionally, before sending the target message to the target terminal, at least one of the following is also included:

[0120] If the priority of the target frequency point is lower than the priority of the frequency point in the other system among all frequency points corresponding to the target terminal, the minimum priority of the target frequency point minus the third preset value is configured as the priority of the frequency point in the other system supported by the target terminal.

[0121] If the priority of the target frequency point is greater than or equal to the priority of the frequency point of the different system among all frequency points corresponding to the target terminal, and if the target frequency band used by the target operator is a preset frequency band, and the priority of the target high frequency point is greater than or equal to the priority of the target low frequency point, then the minimum value of the priority of the target low frequency point minus the fourth preset value is configured as the priority of the target high frequency point of the target terminal.

[0122] If the priority of the target frequency point is greater than or equal to the priority of the frequency point of the different system among all frequency points corresponding to the target terminal, and if the target frequency band used by the target operator is a non-preset frequency band, and the priority of the target high frequency point is less than the priority of the target low frequency point, then the minimum value of the priority of the target high frequency point minus the fifth preset value is configured as the priority of the target low frequency point of the target terminal.

[0123] For example, Figure 3 This is the second schematic diagram of the logic flow for reselection priority configuration provided in the embodiments of this application. Figure 3 Taking the target frequency band as the 5G band, the preset frequency point as the 700MHz band, the target high-frequency point as the 5G high-frequency point, and the target low-frequency point as the 5G low-frequency point as an example, this will be explained accordingly. Figure 3 As shown, the steps to further optimize the priority of each frequency point to determine the specific value of each frequency point in the RRC release message are as follows:

[0124] (1) The base station has obtained all frequency points and priorities of the user.

[0125] (2) Determine whether the priority of the 5G frequency point is greater than or equal to the priority of the frequency point of the other system. There are two cases:

[0126] i. If the priority of the 5G frequency point is greater than or equal to the priority of the frequency point of the other system, then proceed to step (4).

[0127] ii. If the priority of the 5G frequency point is lower than that of the frequency point of the other system, then proceed to step (3).

[0128] The judgment is made based on the frequency points and priority sets of the user that have been obtained, and the priority of 5G frequency points is compared with that of other system frequency points.

[0129] (3) The base station selects the minimum offset 'a' of the 5G frequency point priority as the inter-system frequency point priority: Execute step (4).

[0130] (4) Determine whether the user's operator is a fourth-party operator, which involves two cases:

[0131] i. If the user is a fourth-party operator user, then proceed to step (7).

[0132] ii. If the user is not a user of the fourth operator, then proceed to step (5).
