[0020] The following describes in detail embodiments of the present application, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements, or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present application, and are not to be construed as limiting the present application.

[0021] In related technologies, a UE will prioritize cells with higher frequency priorities for resident use based on the frequency priority provided in a system message or an RRC Release message. However, after a network device configures dedicated uplink resources for a UE in the RRC_IDLE or RRC_INACTIVE state, if the UE continues to select or reselect a cell based on the frequency priority in the system information, it often fails to select a cell configured with the dedicated uplink resources, resulting in a waste of the dedicated uplink resources reserved for the UE. To address the above technical issues, embodiments of the present application provide the following cell selection or reselection method and apparatus.

[0022] S101, obtaining configuration information of an object to which a dedicated uplink resource of a UE belongs, where the configuration information instructs the UE to preferentially use the configuration information to select or reselect a suitable cell to reside, wherein the object to which the dedicated uplink resource belongs includes the frequency point and / or cell to which the dedicated uplink resource belongs.

[0023] In an embodiment of the present application, the dedicated uplink resources of the UE may include: resources on the physical uplink shared channel (PUSCH) and resources on the physical uplink control channel (PUCCH). For example, the dedicated uplink resources on the PUSCH may be pre-allocated uplink resources (PUR) or configured uplink grants (CG). The UE may use the dedicated uplink resources to send data to the network device. Optionally, the data sent to the network is often small data, such as data carried by a data radio bearer (DRB).

[0024] Optionally, the dedicated uplink resource of the UE may be configured by a network device or determined in a pre-agreed manner. For example, the network device may configure a dedicated uplink resource for the UE on frequency-1 or cell-1. Alternatively, a dedicated uplink resource may be configured for the UE on frequency-1 or cell-1 in advance through a protocol. Furthermore, the UE may send data for DRB-1 on the dedicated uplink resource, such as configuration signaling of the configured uplink grant configuration (configuredGrantConfiguration-1).

[0025] Optionally, the UE may receive configuration information of the object to which the exclusive uplink resource belongs sent by the network device. For example, the network device may send the configuration information of the object to which the exclusive uplink resource belongs to the UE in the RRCRelease message, or the network device may send the configuration information of the object to which the exclusive uplink resource belongs to the UE in additional configuration signaling. In some implementations, the network device may send the configuration information of the object to which the exclusive uplink resource belongs to the UE at the same time as sending the exclusive uplink resource to the UE. In some implementations, the network device may also send the configuration information of the object to which the exclusive uplink resource belongs to the UE before or after sending the exclusive uplink resource to the UE. In other implementations, the configuration information of the object to which the exclusive uplink resource belongs may also be determined by the communication standard. In other implementations, the configuration information of the object to which the exclusive uplink resource belongs may also be pre-stored in the UE.

[0026] Furthermore, the configuration information instructs the UE to preferentially use the configuration information of the object to which the dedicated uplink resource belongs to select a suitable cell to camp on. In other words, upon receiving the configuration information, the UE will preferentially verify the selection or reselection of a cell to camp on from the object to which the dedicated uplink resource belongs, i.e., the frequency point and / or cell to which the dedicated uplink resource belongs, in accordance with the configuration information. The frequency point or cell to which the dedicated uplink resource belongs is configured through the configuration information to have a priority opportunity to be selected by the UE.

[0027] S102: Select or reselect a suitable camping cell based on the configuration information of the object to which the dedicated uplink resource belongs.

[0028] In an embodiment of the present application, after obtaining the configuration information of the object to which the exclusive uplink resource belongs, a suitable cell to reside can be selected from the candidate objects of the UE based on the configuration information. The candidate objects include candidate frequencies and / or candidate cells. In some implementations, the candidate objects include at least the object to which the exclusive uplink resource belongs, that is, the frequency and / or cell to which the exclusive uplink resource belongs. In some implementations, the candidate objects may also include some frequency points and / or cells that are not configured with exclusive uplink resources. Optionally, the UE can select a suitable cell to reside from the candidate objects based on the signal quality of the candidate objects, the regional location of the candidate objects and / or the access control information, etc.

[0029] In some implementations, the configuration information may include the priority of some candidate objects and / or the validity period of the configured priority. Optionally, the priority of the object to which some exclusive uplink resources belong or the priority of the adopted radio access technology (Radio Access Technology, RAT) may be configured in the configuration information. In some implementations, the configuration information includes the priority of the object to which the exclusive uplink resource belongs, or the priority of the RAT adopted by the object to which the exclusive uplink resource belongs. Optionally, the configuration information may include not only the priority of the object to which some exclusive uplink resources belong or the priority of the adopted RAT, but also the priority of some candidate objects or the priority of the adopted RAT. In the embodiments of the present application, there is no limitation on the information carried by the configuration information.

[0030] In some implementations, the priority of the object to which the exclusive uplink resource belongs can be configured to be higher in the configuration information of the object to which the exclusive uplink resource belongs. The UE selects a suitable cell to reside in from the candidate objects, i.e., the candidate frequency points and / or candidate cells, based on the priority, so that the UE can access the suitable cell to reside in. In some implementations, the configuration information of the object to which the exclusive uplink resource belongs is configured with an identifier of the object to which the exclusive uplink resource belongs. Since the UE can preferentially use the configuration information for cell selection or reselection, the UE can preferentially select a suitable cell to reside in from the object to which the exclusive uplink resource belongs, so that the UE can reside in the suitable cell to reside, and the UE can try to reside in the frequency points and / or cells configured with the exclusive uplink resource, so that the UE can use the exclusive uplink resource to send data to the network device.

[0031] In an embodiment of the present application, configuration information of an object to which a dedicated uplink resource of a UE belongs is obtained, and the UE performs cell selection or reselection based on the configuration information of the object to which the dedicated uplink resource belongs to obtain a suitable cell to reside, so that the UE can always be in a suitable cell to reside, thereby providing high-quality service to the UE. Furthermore, the configuration information can instruct the UE to preferentially select a suitable cell to reside for the UE from the object to which the dedicated uplink resource belongs, so that the UE can access the suitable cell to reside, thereby enabling the frequency or cell where the dedicated uplink resource is located to have a priority opportunity to be selected by the UE, thereby enabling the UE to reside in the frequency or cell configured with the dedicated uplink resource as much as possible, thereby preventing waste of the dedicated uplink resources reserved for the UE.

[0032] The embodiment of the present application provides another cell selection or reselection method. Figure 2 A flowchart of another cell selection or reselection method provided in an embodiment of the present application is executed by a UE. Figure 2 As shown, the cell selection or reselection method includes the following steps:

[0033] S201: Receive dedicated uplink resources configured for a UE from a network device.

[0034] In some implementations, the network device may send resource configuration information directly to the UE. The resource configuration information may carry dedicated uplink resources configured for the UE. In some implementations, the network device may carry the resource configuration information in an existing message or signaling and send it to the UE via the existing message or signaling. Optionally, the resource configuration information may be carried in an RRCRelease message. The method of sending the resource configuration information in this embodiment is only an example and does not limit the method in which the resource configuration information can be sent.

[0035] S202: Receive configuration information of an object to which a dedicated uplink resource belongs, which is sent by a network device. The configuration information instructs the UE to preferentially use the configuration information to select or reselect a suitable cell to reside in.

[0036] In all embodiments of the present application, the configuration information instructs the UE to preferentially use the configuration information to select or reselect a suitable cell to reside in, that is, the configuration information indicates that the priority of one or more cells is high, or the configuration information indicates to increase the priority of one or more cells.

[0037] Optionally, the UE may receive configuration information of the object to which the exclusive uplink resource belongs sent by the network device. For example, the network device may send the configuration information of the object to which the exclusive uplink resource belongs to the UE in the RRCRelease message, or the network device may send the configuration information of the object to which the exclusive uplink resource belongs to the UE in additional configuration signaling. In some implementations, the network device may send the configuration information of the object to which the exclusive uplink resource belongs to the UE at the same time as sending the exclusive uplink resource to the UE. In some implementations, the network device may also send the configuration information of the object to which the exclusive uplink resource belongs to the UE before or after sending the exclusive uplink resource to the UE. In other implementations, the configuration information of the object to which the exclusive uplink resource belongs may also be determined by the communication standard. In other implementations, the configuration information of the object to which the exclusive uplink resource belongs may also be pre-stored in the UE.

[0038] In some implementations, the configuration information may include at least one of the following: identification information of a camping object designated for the UE, priority information of a frequency point and / or cell and / or RAT, and availability duration of the priority information.

[0039] The identification information of the resident object specified for the UE is explained below. The resident object is at least part of the objects to which the dedicated uplink resource belongs. In some implementations, the identification information of the resident object includes an identifier of the resident object and / or an identifier of the radio access technology RAT used by the resident object.

[0040] For example, the objects to which the dedicated uplink resources belong include N frequencies and / or cells using a new radio access technology (Radio Access Technology, RAT). The configuration information may include selecting K from the N frequencies and / or cells using a new RAT (New RAT, NR) as resident objects designated for the UE, where N ≥ 1 and 1 ≤ K ≤ N. In implementation, the configuration information will carry identification information of the K resident objects. Optionally, the identification information of the resident objects includes at least one of the following:

[0041] Frequency mark and / or cell identifier, for example, the frequency identifier may include an Absolute Radio Frequency Channel Number (ARFCN).

[0042] The RAT identifier, for example, the NR identifier or the Evolved Universal Terrestrial Radio Access (EUTRA) identifier, can be used to indicate the radio access technology used by the resident frequency point and / or the resident cell.

[0043] The following explains frequency and / or cell and / or RAT priority information. Frequency and / or cell and / or RAT priority information includes at least one of the following: identification information of the frequency and / or cell and / or RAT, and priority of the frequency and / or cell and / or RAT. The priority of the frequency and / or cell and / or RAT includes a selection or reselection priority and a selection or reselection sub-priority. For example, a selection or reselection priority of 1 and a selection or reselection sub-priority of 0.4 can be configured.

[0044] In some implementations, the frequencies configured with priority information may include the resident frequencies or at least some of the frequencies to which dedicated uplink resources belong. In some implementations, the frequencies configured with priority information may include the resident frequencies and at least some of the frequencies to which dedicated uplink resources belong.

[0045] In some implementations, the cells configured with priority information may include the camped cell or at least some of the cells to which the dedicated uplink resource belongs. In some implementations, the cells configured with priority information may include the camped cell and at least some of the cells to which the dedicated uplink resource belongs.

[0046] In some implementations, the RAT configured with priority information may be the RAT used by at least some of the objects to which the resident object or dedicated uplink resources belong. In some implementations, the RAT configured with priority information may include the RAT used by at least some of the objects to which the resident object or dedicated uplink resources belong.

[0047] For example, if there are N objects belonging to a dedicated uplink resource, the network device may configure priority information for some or all of the N objects and include the priority information for some or all of the N objects in the configuration information, where N ≥ 1. For another example, RATs may include NR and EUTRA. Priority information for NR or EUTRA may be specified in the configuration information, or the order of the priority information for NR and EUTRA may be specified.

[0048] The following explains the duration of availability of the priority information of the frequency point and / or cell and / or RAT. In some possible implementations, the priority information of the frequency point and / or cell and / or RAT has a certain duration of availability. During this duration, the priority information of the frequency point and / or cell and / or RAT is valid. Beyond this duration, the priority information of the frequency point and / or cell and / or RAT becomes invalid. For example, a timer can be provided, which starts counting from the time when the configuration information is received or at another appropriate time point. The duration of the timer is the duration of availability of the priority information of the frequency point and / or cell and / or RAT. When the timer times out, the priority information of the frequency point and / or cell and / or RAT becomes invalid.

[0049] S203: Select or reselect a suitable camping cell based on the configuration information of the object to which the dedicated uplink resource belongs.

[0050] As a possible implementation, in response to the configuration information including identification information of a camping object specified for the UE, a suitable target cell for the UE to camp on may be selected from candidate objects corresponding to the UE based on the identification information of the camping object. In some possible implementations, multiple suitable target cells for the UE to camp on may be selected from candidate objects corresponding to the UE based on the identification information of the camping object; and then a target cell for the UE to camp on may be finally determined based on other information.

[0051] Optionally, in response to the identification information of the resident object being the identifier of the resident object, the selection or reselection priority of the resident object is set to the highest priority, and according to the highest priority of the resident object, a suitable target cell for resident is selected from the candidate objects corresponding to the UE for resident. That is, the UE first sets the selection or reselection priority of the resident frequency point and / or resident cell identified by the identifier of the resident object to the highest. Further, after the setting is completed, since the selection or reselection priority of the resident object is the highest, when selecting from the candidate objects, the UE will select according to the priority, so that a suitable cell for resident is preferentially selected from the resident object as the target cell, and the UE accesses the target cell for resident.

[0052] Optionally, in response to the identification information of the resident object being a RAT identifier, the target RAT identified by the RAT identifier is set as the RAT with the highest priority, and a target cell suitable for resident using the target RAT is selected from the candidate objects corresponding to the UE for resident. That is, the UE first sets the priority of the target RAT identified by the RAT identifier to the highest. For example, NR can be set as the RAT with the highest priority. Furthermore, after the setting is completed, due to the priority of NR and the resident frequency and / or resident cell adopting NR, when selecting from the candidate objects, the UE will give priority to selecting a suitable resident cell from the resident frequency and / or resident cell of NR as the target cell, and the UE accesses the target cell for resident.

[0053] Optionally, in response to the identification information of the resident object being the identifier of the resident object, before selecting other candidate objects, a suitable target cell for resident selection is selected from the resident objects designated for the UE for resident selection. In other words, the UE has candidate objects, some of which are designated as resident objects. In this embodiment of the present application, the configuration information is configured with identifiers designated as resident objects, and the UE can be instructed to select a suitable target cell for resident selection from the resident objects for resident selection before selecting other candidate objects.

[0054] Optionally, in response to the identification information of the resident object being a RAT identifier, before selecting other candidate objects, the indicated target RAT is first determined based on the RAT identifier, and a suitable resident target cell that adopts the target RAT is selected from the candidate objects of the UE for residence. In some implementations, the RAT identifier of the adopted RAT can be configured in the configuration information of the object to which the dedicated uplink resource belongs, based on the RAT adopted by the object to which the dedicated uplink resource belongs. Accordingly, after receiving the configuration information, the UE preferentially selects a suitable resident target cell from the candidate objects based on the RAT identifier in the configuration information, wherein the RAT adopted by the suitable resident target cell is the RAT identified by the RAT identifier. The candidate objects may include the object to which the dedicated uplink resource belongs. The candidate objects may also include the resident objects specified for the UE.

[0055] For example, if the object to which the dedicated uplink resource belongs adopts NR, it can be determined that the RAT identifier is NR-1. When selecting a suitable target cell to reside in from the candidate objects, the object adopting NR will be given priority, and the suitable target cell to reside in can be selected from the designated resided objects first. In some implementations,

[0056] Optionally, in response to the identification information of the resident object including the resident object's identifier and the RAT identifier, before selecting other candidate objects, the resident object using the target RAT is first selected as a suitable target cell for residency based on the RAT identifier and the resident object's identifier. That is, the number of candidate objects is narrowed down based on the resident object's identifier, and the candidate objects obtained after the narrowing down are the resident objects. Based on the RAT identifier, a resident object of the target RAT identified by the RAT identifier is selected from the resident objects as a suitable target cell for residency. Optionally, the number of candidate objects is narrowed down based on the RAT identifier, and further, based on the resident object's identifier, a suitable cell for residency is selected or reselected from the candidate objects obtained after the narrowing down. When the candidate objects are narrowed down based on the RAT identifier, the candidate objects obtained after the narrowing down may include not only the resident object, but also other candidate objects.

[0057] As a possible implementation, in response to configuration information including priority information of frequency points and / or cells and / or RATs, the UE selects or reselects a suitable target cell to reside in based on the configured priority information. Optionally, the UE may sort the priority information of the frequency points and / or cells and / or RATs, and select a suitable target cell to reside in from the corresponding candidate objects of the frequency points and / or cells and / or RATs according to the sorting of the priority information. In some implementations, the frequency points and / or cells to which the dedicated uplink resources belong and / or the RAT used may be given a higher priority, thereby instructing the UE to select a suitable target cell to reside in from the cell configured with the dedicated uplink resources.

[0058] As another possible implementation, in response to the configuration information including the duration of availability of the priority information of the frequency and / or cell and / or RAT, the UE needs to select or reselect a cell based on the identification information of the frequency and / or cell and / or RAT and the priority information of the frequency and / or cell and / or RAT within the available time of the priority information. For example, a timer starts counting from the time the configuration information is received, and when the available time of the priority information of the frequency and / or cell and / or RAT is reached, the priority information of the frequency and / or cell and / or RAT becomes invalid.

[0059] In some implementations, the UE selects or reselects a suitable cell to camp on based on the identification information of the frequency, and the cell selection or reselection priority and / or cell selection or reselection sub-priority corresponding to the frequency in the frequency priority information, within the available duration of the frequency priority information. In some implementations, the UE selects or reselects a suitable cell to camp on based on the identification information of the cell, and the cell selection or reselection priority and / or cell selection or reselection sub-priority of the cell corresponding to the cell in the cell priority information, within the available duration of the cell priority information. In some implementations, the UE selects or reselects a suitable cell to camp on based on the cell selection or reselection priority and / or cell selection or reselection sub-priority of the cell in the cell priority information, within the available duration of the RAT priority information.

[0060] In an embodiment of the present application, configuration information of an object to which a dedicated uplink resource of a UE belongs is obtained, and the UE performs cell selection or reselection based on the configuration information of the object to which the dedicated uplink resource belongs to obtain a suitable cell to reside, so that the UE can always be in a suitable cell to reside, thereby providing high-quality service to the UE. Furthermore, the configuration information can instruct the UE to preferentially select a suitable cell to reside for the UE from the object to which the dedicated uplink resource belongs, so that the UE can access the suitable cell to reside, thereby enabling the frequency or cell where the dedicated uplink resource is located to have a priority opportunity to be selected by the UE, thereby enabling the UE to reside in the frequency or cell configured with the dedicated uplink resource as much as possible, thereby preventing waste of the dedicated uplink resources reserved for the UE.

[0061] In each embodiment of the present application, multiple suitable target cells for the UE to camp on can be selected from the candidate objects corresponding to the UE; and then a target cell can be finally determined for the UE to camp on based on other information.

[0062] The embodiment of the present application provides another cell selection or reselection method. Figure 3 A flowchart of another cell selection or reselection method provided in an embodiment of the present application is executed by a UE. Figure 3 As shown, the cell selection or reselection method includes the following steps:

[0063] S301: Receive configuration information of an object to which a dedicated uplink resource belongs sent by a network device, where the configuration information instructs the UE to preferentially select a suitable cell to reside in from the object to which the dedicated uplink resource belongs.

[0064] In all embodiments of the present application, the configuration information instructs the UE to preferentially use the configuration information to select or reselect a suitable cell to reside in, that is, the configuration information indicates that the priority of one or more cells is high, or the configuration information indicates to increase the priority of one or more cells.

[0065] For a detailed description of step S301, please refer to the relevant contents in the above embodiment, which will not be repeated here.

[0066] S302: Receive configuration information of a dedicated object configured for a UE from a network device, where the dedicated object includes a dedicated frequency point and / or a dedicated cell.

[0067] Optionally, when the network device sends the configuration information of the object to which the dedicated uplink resource belongs to the UE, the network device may further configure the configuration information of the dedicated object, for example, by configuring the configuration information of an additional dedicated object through the RRCRelease message. The configuration information of the dedicated object includes at least one of the following:

[0068] identification information of at least some of the exclusive objects;

[0069] Priority information for exclusive objects;

[0070] How long the priority information of a dedicated object is available.

[0071] S303: Select or reselect a suitable camping cell based on the configuration information of the object to which the dedicated uplink resource belongs.

[0072] For a detailed description of step S303, please refer to the relevant contents in the above embodiment, which will not be repeated here.

[0073] S304 : In response to the dedicated uplink resource being unavailable, selecting or reselecting a suitable camping cell based on the configuration information of the dedicated object.

[0074] Optionally, in the embodiment of the present application, the condition for determining whether the dedicated uplink resource is no longer available includes at least one of the following:

[0075] The uplink transmission of the dedicated uplink resource is no longer synchronized. For example, the uplink synchronization timer corresponding to the uplink transmission of the dedicated uplink resource CG-1 times out, which means that the subframe or time slot positions of the uplink transmission are no longer aligned.

[0076] The usage duration of the dedicated uplink resource exceeds the configured availability duration. For example, the network device configures the dedicated uplink resource CG-1 for the UE through the RRCRelease message, and configures the availability duration of the CG-1 to be 100ms. After receiving the configuration information of the CG-1, the UE starts a timer (such as cg-ValidationTimer) and sets the timer duration to 100ms. When the timer expires, the UE considers that the CG-1 is no longer available.

[0077] When the dedicated uplink resource is unavailable, the configuration information of the object to which the dedicated uplink resource belongs will also become invalid, that is, it will no longer be available. In the embodiment of the present application, when the configuration information of the dedicated object is configured, the UE can select a suitable target cell for it to reside in from the candidate objects based on the configuration information of the dedicated object. The process of selecting a suitable target cell to reside in based on the configuration information of the dedicated object is similar to the process of selecting a suitable target cell to reside in based on the configuration information of the object to which the dedicated uplink resource belongs in the above embodiment, and will not be repeated here.

[0078] It should be noted that if Figure 4 As shown, the configuration information of the exclusive object may include the available time of the priority information of the exclusive object. Figure 4As shown, time t1 is the start time of the available duration of the priority information of the object in the configuration information of the object to which the dedicated uplink resource belongs, and time t2 is the end time of the available duration of the priority information of the object. At the same time, time t2 is the start time of the timer corresponding to the available duration of the priority information of the dedicated object, and ends at time t3. When the available duration timer of the priority information of the dedicated object reaches time t3, the UE considers that the priority information of the dedicated object is no longer available.

[0079] It should be noted that if the network device does not configure a dedicated object and configuration information of the dedicated object for the UE, the UE uses the priority information configured in the system information to select a suitable target cell for the UE to reside in from the candidate objects.

[0080] In an embodiment of the present application, after the configuration information of the object to which the exclusive uplink resource belongs obtained by the UE and / or the exclusive uplink resource becomes invalid, the UE selects or reselects a suitable cell to reside based on the configuration information of the exclusive object to obtain a suitable cell to reside in, so that the UE can always be in a suitable cell to reside, thereby being able to provide high-quality services to the UE.

[0081] The embodiment of the present application provides another cell selection or reselection method. Figure 5 A flowchart of another cell selection or reselection method provided in an embodiment of the present application is executed by a UE. Figure 5 As shown, the cell selection or reselection method includes the following steps:

[0082] S501: Receive configuration information of an object to which a dedicated uplink resource belongs, sent by a network device, wherein the object to which the dedicated uplink resource belongs includes a frequency point and / or a cell to which the dedicated uplink resource belongs.

[0083] In all embodiments of the present application, the configuration information instructs the UE to preferentially use the configuration information to select or reselect a suitable cell to reside in, that is, the configuration information indicates that the priority of one or more cells is high, or the configuration information indicates to increase the priority of one or more cells.

[0084] For a detailed description of step S501, please refer to the relevant contents in the above embodiment, which will not be repeated here.

[0085] S502: Select or reselect a suitable camping cell based on the configuration information of the object to which the dedicated uplink resource belongs.

[0086] For a detailed description of step S502, please refer to the relevant contents in the above embodiment, which will not be repeated here.

[0087] S503: In response to the dedicated uplink resource being unavailable, delete or suspend the configuration information of the object to which the dedicated uplink resource belongs and / or the dedicated uplink resource.

[0088] Regarding the judgment condition that the dedicated uplink resource is no longer available, reference may be made to the relevant contents in the above embodiments, which will not be repeated here.

[0089] When the exclusive uplink resource is unavailable, the configuration information of the object to which the exclusive uplink resource belongs will also become invalid, that is, it will no longer be available. In an embodiment of the present application, the UE can delete or suspend the configuration information of the exclusive uplink resource and / or the object to which the uplink resource belongs. For example, the UE receives the CG-1 resource belonging to frequency-1 or cell-1 configured by the network device in the RRCRelease message. When the uplink transmission of the CG-1 resource is no longer synchronized, it means that the CG-1 resource is no longer available. Optionally, the UE deletes or suspends the configuration information of the frequency-1 or cell-1 corresponding to the CG-1 resource, or the UE deletes or suspends the CG-1 resource, or the UE deletes or suspends both the configuration information of the frequency-1 or cell-1 corresponding to the CG-1 resource and the CG-1 resource.

[0090] In an embodiment of the present application, after the configuration information of the object to which the dedicated uplink resource belongs and / or the dedicated uplink resource acquired by the UE becomes invalid, the UE deletes or suspends the configuration information of the object to which the dedicated uplink resource belongs and / or the dedicated uplink resource to facilitate the release of the resource.

[0091] This embodiment provides another cell selection or reselection method. Figure 6 This is a flow chart of another cell selection or reselection method provided in an embodiment of the present application, which is executed by a network device. Figure 6 As shown, the cell selection or reselection method includes the following steps:

[0092] S601, sending configuration information of an object to which a dedicated uplink resource belongs to a UE, where the configuration information is used to instruct the UE to select or reselect a suitable cell to which the dedicated uplink resource belongs based on the configuration information, wherein the object to which the dedicated uplink resource belongs includes the frequency point and / or cell to which the dedicated uplink resource belongs.

[0093] In all embodiments of the present application, the configuration information instructs the UE to preferentially use the configuration information to select or reselect a suitable cell to reside in, that is, the configuration information indicates that the priority of one or more cells is high, or the configuration information indicates to increase the priority of one or more cells.

[0094] In the embodiment of the present application, the dedicated uplink resources of the UE may include: resources on the PUSCH and resources on the PUCCH. For example, the dedicated uplink resources on the PUSCH may be PUR resources or CG resources.

[0095] Optionally, the dedicated uplink resources of the UE may be configured through network equipment, or may be determined in a pre-agreed manner.

[0096] In an embodiment of the present application, the network device may send configuration information of the object to which the exclusive uplink resource belongs to to the UE. For example, the network device may send configuration information of the object to which the exclusive uplink resource belongs to to the UE in an RRCRelease message, and the network device may also send configuration information of the object to which the exclusive uplink resource belongs to to the UE in some configuration signaling. In some implementations, the network device may send configuration information of the object to which the exclusive uplink resource belongs to the UE while sending the exclusive uplink resource to the UE. In some implementations, the network device may also send configuration information of the object to which the exclusive uplink resource belongs to the UE after sending the exclusive uplink resource to the UE.

[0097] Optionally, the network device may configure dedicated uplink resources for the UE on frequency-1 or cell-1, or pre-agreed through a protocol to configure dedicated uplink resources for the UE on frequency-1 or cell-1.

[0098] In an embodiment of the present application, after obtaining the configuration information of the object to which the exclusive uplink resource belongs, a suitable cell to reside can be selected from the candidate objects of the UE based on the configuration information. The candidate objects include at least the object to which the exclusive uplink resource belongs, that is, the frequency point and / or cell to which the exclusive uplink resource belongs. In some implementations, the candidate objects may also include some frequency points and / or cells that are not configured with exclusive uplink resources. Optionally, the UE can select a suitable cell to reside from the candidate objects based on the signal quality of the candidate objects, the regional location of the candidate objects, and access control information.

[0099] In some implementations, the configuration information may include the priority of some candidate objects and / or the validity period of the configured priority. Optionally, the priority of the object to which some exclusive uplink resources belong or the adopted RAT priority may be configured in the configuration information. In some implementations, the configuration information includes the priority of the object to which the exclusive uplink resource belongs, or the priority of the RAT adopted by the object to which the exclusive uplink resource belongs. Optionally, the configuration information may include not only the priority of the object to which some exclusive uplink resources belong or the adopted RAT priority, but also the priority of some candidate objects or the adopted RAT priority. In the embodiments of the present application, there is no limitation on the information carried by the configuration information.

[0100] In some implementations, when the candidate objects are configured with priorities, if the priority of the object where the exclusive uplink resource is located is higher, the UE selects a suitable cell to reside in from the candidate objects, i.e., the candidate frequency points and / or candidate cells, based on the priority, so that the UE can access the suitable cell to reside in. In some implementations, the object where the exclusive uplink resource is located is configured with a priority, while the frequency points or cells that are not configured with exclusive uplink resources are not configured with a priority, which similarly enables the frequency points or cells where the exclusive uplink resource is located to be preferentially selected by the UE. The configuration information of the object to which the exclusive uplink resource belongs in the above two implementations can instruct the UE to preferentially select a suitable cell to reside in from the object to which the exclusive uplink resource belongs, so that the UE resides in the suitable cell to reside, and can enable the UE to reside in the frequency points and / or cells configured with exclusive uplink resources as much as possible, so that the UE can use the exclusive uplink resource to send data to the network device.

[0101] In an embodiment of the present application, configuration information of an object to which a dedicated uplink resource belongs can be sent to a UE, so that the UE can perform cell selection or reselection based on the configuration information of the object to which the dedicated uplink resource belongs, to obtain a suitable cell to reside, so that the UE can always be in a suitable cell to reside, thereby providing high-quality service to the UE. Moreover, the configuration information can instruct the UE to preferentially select a suitable cell to reside in from the object to which the dedicated uplink resource belongs, so that the UE can access the suitable cell to reside, thereby enabling the frequency or cell where the dedicated uplink resource is located to have a priority opportunity to be selected by the UE, thereby enabling the UE to reside in the frequency or cell configured with the dedicated uplink resource as much as possible, thereby preventing waste of the dedicated uplink resources reserved for the UE.

[0102] Optionally, the configuration information of the object to which the dedicated uplink resource belongs includes at least one of the following: identification information of the resident object designated for the UE, priority information of the frequency and / or cell and / or RAT, and available duration of the priority information of the frequency and / or cell and / or RAT. Optionally, the identification information of the resident object includes at least one of the following: an identifier of the resident object and an identifier of the radio access technology (RAT) used by the resident object.

[0103] Optionally, the priority information of the frequency and / or cell and / or RAT includes at least one of the following: the identifier of the frequency and / or cell and / or RAT, and the priority of each frequency and / or cell and / or RAT, wherein the priority of the frequency and / or cell and / or RAT includes the selection or reselection priority and the selection or reselection sub-priority.

[0104] For a detailed introduction to the configuration information, please refer to the relevant contents in the above embodiments, which will not be repeated here.

[0105] The embodiment of the present application provides another cell selection or reselection method. Figure 7 This is a flow chart of another cell selection or reselection method provided in an embodiment of the present application, which is executed by a network device. Figure 7 As shown, the cell selection or reselection method includes the following steps:

[0106] S701, sending configuration information of the object to which the dedicated uplink resource belongs to the UE, where the configuration information is used to instruct the UE to preferentially use the configuration information to select or reselect a suitable cell to which the dedicated uplink resource belongs, wherein the object to which the dedicated uplink resource belongs includes the frequency point and / or cell to which the dedicated uplink resource belongs.

[0107] In all embodiments of the present application, the configuration information instructs the UE to preferentially use the configuration information to select or reselect a suitable cell to reside in, that is, the configuration information indicates that the priority of one or more cells is high, or the configuration information indicates to increase the priority of one or more cells.

[0108] For a detailed description of step S701, please refer to the relevant contents in the above embodiment, which will not be repeated here.

[0109] S702: Send configuration information of a dedicated object to the UE, where the dedicated object includes a dedicated frequency and / or a dedicated cell.

[0110] Optionally, when the network device sends the configuration information of the object to which the dedicated uplink resource belongs to the UE, the network device may further configure the configuration information of the dedicated object, for example, by configuring the configuration information of an additional dedicated object through the RRCRelease message. The configuration information of the dedicated object includes at least one of the following:

[0111] identification information of at least some of the exclusive objects;

[0112] Priority information for exclusive objects;

[0113] How long the priority information of a dedicated object is available.

[0114] In response to the dedicated uplink resource being unavailable, the UE may select or reselect a suitable camped cell based on the configuration information of the dedicated object.

[0115] When the dedicated uplink resource is unavailable, the configuration information of the object to which the dedicated uplink resource belongs will also become invalid, that is, it will no longer be available. In the embodiment of the present application, when the configuration information of the dedicated object is configured, the UE can select a suitable target cell for it to reside in from the candidate objects based on the configuration information of the dedicated object. The process of selecting a suitable target cell to reside in based on the configuration information of the dedicated object is similar to the process of selecting a suitable target cell to reside in based on the configuration information of the object to which the dedicated uplink resource belongs in the above embodiment, and will not be repeated here.

[0116] In an embodiment of the present application, the network device not only sends the configuration information of the object to which the exclusive uplink resource belongs to the UE, but also sends the configuration information of the exclusive object to the UE, so that after the configuration information of the object to which the exclusive uplink resource belongs and / or the exclusive uplink resource becomes invalid, the UE can select or reselect a suitable cell to reside based on the configuration information of the exclusive object to obtain a suitable cell to reside, so that the UE can always be in a suitable cell to reside, thereby being able to provide high-quality services to the UE.
