Detailed Description

Reference will now be made in detail to embodiments of the present application, examples of which are illustrated in the accompanying drawings, wherein like or similar reference numerals refer to the same or similar elements or elements having the same or similar function throughout. The embodiments described below with reference to the drawings are illustrative and intended to be used for explaining the present application and should not be construed as limiting the present application.

In the related art, the UE preferentially selects a cell with a high frequency point priority for camping according to the frequency priority provided in the system message or the RRC Release (Release) message. However, after the network device configures the dedicated uplink resource for the UE in the RRC _ IDLE state or the RRC _ INACTIVE state, if the UE continues to select or reselect the cell according to the priority of the frequency point in the system information, the cell configured with the dedicated uplink resource is often not selected, which results in a waste of the dedicated uplink resource reserved for the UE. In order to solve the above technical problem, embodiments of the present application provide the following cell selection or reselection method and apparatus.

S101, obtaining configuration information of an object to which an exclusive uplink resource of UE belongs, wherein the configuration information indicates that the UE preferentially uses the configuration information to select or reselect a cell suitable for residing, and the object to which the exclusive uplink resource belongs comprises a frequency point and/or a cell to which the exclusive uplink resource belongs.

In this embodiment, the dedicated uplink resource of the UE may include: a Resource on a Physical Uplink Shared Channel (PUSCH), a Resource on a Physical Uplink Control Channel (PUCCH), for example, a dedicated Uplink Resource on the PUSCH may be a pre-allocated Uplink Resource (PUR) or a Configured Uplink Grant (CG). The UE may send data to the network device using the dedicated uplink resource. Optionally, the Data sent to the network is often Small Data (Small Data), for example, data that may be a Data Radio Bearer (DRB).

Optionally, the dedicated uplink resource of the UE may be configured by the network device, or may be determined in a predetermined manner, for example, the network device may configure the dedicated uplink resource on the frequency point-1 or the cell-1 for the UE. Or, configuring exclusive uplink resources for the UE on the frequency point-1 or the cell-1 by protocol agreement in advance. Further, the UE may send data of DRB-1 on the dedicated uplink resource, for example, configuration signaling (configured grant configuration-1) of configured uplink grant configuration.

Optionally, the UE may receive configuration information of the dedicated uplink resource object sent by the network device, for example, the network device may send the configuration information of the dedicated uplink resource object to the UE in an rrcreelease message, and the network device may also send the configuration information of the dedicated uplink resource object to the UE in an additional configuration signaling. In some implementations, the network device may send the UE the configuration information of the object to which the dedicated uplink resource belongs while sending the dedicated uplink resource to the UE. In some implementations, the network device may also send the configuration information of the object to which the dedicated uplink resource belongs to the UE before or after sending the dedicated uplink resource to the UE. In other implementations, the configuration information of the object to which the dedicated uplink resource belongs may also be determined by a communication standard. In other implementations, the configuration information of the dedicated uplink resource object may also be pre-stored in the UE.

Further, the configuration information indicates that the UE preferentially uses the configuration information of the object to which the dedicated uplink resource belongs to select a cell suitable for camping. That is to say, when the UE receives the configuration information, it preferentially selects or reselects the verification resident cell from the object to which the dedicated uplink resource belongs, i.e. the frequency point and/or the cell to which the dedicated uplink resource belongs, and configures the opportunity preferentially selected by the UE for the frequency point or the cell to which the dedicated uplink resource belongs through the configuration information.

And S102, selecting or reselecting a proper resident cell based on the configuration information of the object to which the exclusive uplink resource belongs.

In the embodiment of the present application, after the configuration information of the object to which the dedicated uplink resource belongs is obtained, a cell suitable for residing can be selected from candidate objects of the UE based on the configuration information. The candidate objects comprise candidate frequency points and/or candidate cells. In some implementations, the candidate objects at least include an object to which the dedicated uplink resource belongs, that is, a frequency point and/or a cell to which the dedicated uplink resource belongs. In some implementations, the candidate object may further include a part of frequency points and/or cells where the dedicated uplink resource is not configured. Alternatively, the UE may select a cell suitable for camping from the candidates based on the signal quality of the candidates, the regional location of the candidates, and/or the access control information.

In some implementations, the priority of the partial candidate and/or the effective duration of the configuration priority may be included in the configuration information. Optionally, a priority of an object to which the partially dedicated uplink resource belongs or a Radio Access Technology (RAT) priority to be used may be configured in the configuration information. In some implementations, the configuration information includes a priority of an object to which the dedicated uplink resource belongs, or a priority of a RAT employed by the object to which the dedicated uplink resource belongs. Optionally, the configuration information may include not only the priority of the object to which the part of dedicated uplink resources belong or the priority of the adopted RAT, but also the priority of the part of candidate objects or the priority of the adopted RAT. In the embodiment of the present application, the information carried by the configuration information is not limited.

In some implementations, in the configuration information of the dedicated uplink resource belonging object, the priority of the dedicated uplink resource belonging object configured may be higher, and the UE selects a cell suitable for residing from candidate objects, that is, candidate frequency points and/or candidate cells, based on the priority, so that the UE accesses the cell suitable for residing. In some implementations, the configuration information of the dedicated uplink resource object is configured with an identifier of the dedicated uplink resource object, and the UE can preferentially use the configuration information to perform cell selection or reselection, so that the UE can preferentially select a cell suitable for camping from the dedicated uplink resource object, so that the UE camps in the cell suitable for camping, and the UE can camp on a frequency point and/or a cell configured with the dedicated uplink resource as much as possible, so that the UE can use the dedicated uplink resource to send data to the network device.

In the embodiment of the application, the configuration information of the object to which the dedicated uplink resource of the UE belongs is acquired, and the UE performs cell selection or reselection based on the configuration information of the object to which the dedicated uplink resource belongs to acquire a cell which is suitable to reside, so that the UE can be always in the cell which is suitable to reside, and thus high-quality service can be provided for the UE. And the configuration information can indicate that the UE preferentially selects a cell suitable for residing from the object to which the exclusive uplink resource belongs to facilitate the UE to access the cell suitable for residing, so that the frequency point or the cell where the exclusive uplink resource exists has a chance of being preferentially selected by the UE, the UE can further reside in the frequency point or the cell configured with the exclusive uplink resource as much as possible, and waste of the exclusive uplink resource reserved for the UE is prevented.

Fig. 2 is a schematic flow chart of another cell selection or reselection method provided in this embodiment and executed by a UE. As shown in fig. 2, the cell selection or reselection method includes the following steps:

s201, receiving dedicated uplink resources configured for the UE and sent by the network equipment.

In some implementations, the network device may send the 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 the existing message or signaling to the UE. Optionally, the resource configuration information may be carried in the rrcreelease message. The sending method of the resource configuration information in this embodiment is only an example, and the method for sending the resource configuration information is not limited here.

S202, receiving configuration information of an object to which the dedicated uplink resource belongs, wherein the configuration information indicates that the UE preferentially uses the configuration information to select or reselect a cell where the UE suitably resides.

In all embodiments of the present application, the configuration information indicates that the UE preferentially uses the configuration information to select or reselect a cell where the UE is camped on, that is, the configuration information indicates that the priority of one or more cells is high, or the configuration information indicates that the priority of one or more cells is increased.

In some implementations, the configuration information may include at least one of: and the identification information of the resident object, the frequency point and/or the priority information of the cell and/or the RAT and the available duration of the priority information are designated for the UE.

The following explains the identification information of the resident object designated for the UE, where the resident object is at least part of the objects belonging to the dedicated uplink resource. In some implementations, the identification information of the resident object includes an identification of the resident object and/or an identification of a radio access technology, RAT, employed by the resident object.

For example, the object to which the dedicated uplink resource belongs includes N frequency points and/or cells using a New Radio Access Technology (RAT), and the configuration information may include K frequency points and/or cells using a New RAT (NR) as the camping object designated for the UE, where N ≧ 1,1 ≦ K ≦ N. In implementation, the configuration information may carry identification information of K resident objects, and optionally, the identification information of the resident objects includes at least one of the following items:

frequency bin punctuation and/or cell identification, for example, the Frequency bin identification may include an Absolute Radio Frequency Channel Number (ARFCN).

RAT identities, for example, identities of NRs or identities of Evolved Universal Terrestrial Radio Access (EUTRA). Through the RAT identification, the resident frequency point and/or the wireless access technology adopted by the resident cell can be indicated.

In the following, priority information of a frequency point and/or a cell and/or a RAT is explained, where the priority information of a frequency point and/or a cell and/or a RAT includes at least one of the following: the method comprises the identification information of the frequency point and/or the cell and/or the RAT, and the priority of the frequency point and/or the cell and/or the RAT, wherein the priority of the frequency point and/or the cell and/or the RAT comprises a selection or reselection priority and a selection or reselection sub-priority. For example, a selection or reselection priority of 1 may be configured, and a selection or reselection sub-priority of 0.4 may be configured.

In some implementations, the frequency points configured with the priority information may include at least some of the frequency points belonging to the camping frequency point or the dedicated uplink resource. In some implementations, the frequency points configured with the priority information may include at least some of the camping frequency points and the frequency points to which the dedicated uplink resources belong.

In some implementations, the cells configured with priority information may include at least some of the camped cells or the cells to which dedicated uplink resources belong. The cells configured with priority information in some implementations may include at least some of the camped cells and the cells to which dedicated uplink resources belong.

In some implementations, the RAT configured with the priority information may be a RAT employed by at least some of the camping object or the object to which the dedicated uplink resource belongs. The RAT configured with priority information in some implementations may include a RAT employed by at least some of the camping object and the object to which the dedicated uplink resource belongs.

For example, the dedicated uplink resource includes N objects, and the network device may configure priority information of some or all of the N objects, and carry the priority information of some or all of the N objects in the configuration information, where N ≧ 1. As another example, RATs may include NR and EUTRA. Priority information of NR or EUTRA or the order of priority information of NR and EUTRA may be specified in the configuration information.

In some possible implementations, the priority information of the frequency point and/or the cell and/or the RAT has a certain available duration, within the available duration, the priority information of the frequency point and/or the cell and/or the RAT is valid, and beyond the available duration, the priority information of the frequency point and/or the cell and/or the RAT fails. For example, a timer may be provided, and the timer is started to time from the reception of the configuration information or other appropriate time point, and the timer timing duration is the available duration of the priority information of the frequency point and/or the cell and/or the RAT; and if the timer is timed out, the priority information of the frequency point and/or the cell and/or the RAT is invalid.

S203, based on the configuration information of the object to which the exclusive uplink resource belongs, selecting or reselecting a proper resident cell.

As a possible implementation manner, when the configuration information includes identification information of a camping object specified for the UE, a target cell suitable for camping is selected for the UE from candidate objects corresponding to the UE for camping on based on the identification information of the camping object. In some possible implementation manners, a plurality of target cells suitable for residing are selected for the UE from candidate objects corresponding to the UE for residing on the basis of the identification information of the residing object; and finally determining a target cell for residing according to other information.

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

Optionally, in response to that the identification information of the camping object is the RAT identification, the target RAT identified by the RAT identification is set to the RAT with the highest priority, and one target cell where the target RAT is suitably camped is selected from candidate objects corresponding to the UE for camping. That is, the UE first sets the priority of the target RAT identified by the RAT identification to be highest, e.g., NR may be set to the highest priority RAT. Further, after the setting is completed, since the NR priority and the NR is used for the camping frequency point and/or the camping cell, when the UE selects from the candidate objects, the UE preferentially selects a suitable camping cell from the NR camping frequency point and/or the camping cell as the target cell, and the UE accesses the target cell to camp.

Optionally, in response to that the identification information of the resident object is the identification of the resident object, before selecting another candidate object, a suitable resident target cell is selected from the resident objects designated for the UE to be resident. That is to say, the UE has candidate objects, wherein a part of the candidate objects are designated as camping objects, and in the embodiment of the present application, if the identifier designated as camping objects is configured in the configuration information, the UE may be instructed to select a target cell suitable for camping from the camping objects to camp on before selecting other candidate objects.

Optionally, in response to that the identification information of the camping object is the RAT identification, before selecting another candidate object, the indicated target RAT is determined according to the RAT identification, and a target cell suitable for camping using the target RAT is selected from the candidate object of the UE for camping. In some implementations, the RAT identifier of the employed RAT may be configured in the configuration information of the dedicated uplink resource belonging object based on the RAT employed by the dedicated uplink resource belonging object. Correspondingly, after receiving the configuration information, the UE preferentially selects a target cell suitable for camping from the candidate objects based on the RAT identifier in the configuration information, wherein the RAT adopted by the target cell suitable for camping is the RAT identified by the RAT identifier. The candidate object may include an object to which the dedicated uplink resource belongs. The candidates may also include a resident object designated for the UE.

For example, when the object to which the dedicated uplink resource belongs adopts NR, it may be determined that the RAT identifier is NR-1, and when a target cell suitable for camping is selected from the candidate objects, the object adopting NR may be preferentially considered, and the target cell suitable for camping may be selected from the designated camping objects. In some implementations, the first and second sensors are,

optionally, in response to that the identification information of the resident object includes the identifier of the resident object and the RAT identifier, before selecting another candidate object, selecting the resident object adopting the target RAT as the target cell suitable for residing according to the RAT identifier and the identifier of the resident object. That is to say, the number of candidate objects is reduced based on the identifier of the resident object, the candidate object obtained after the range reduction is the resident object, and based on the RAT identifier, the resident object of the target RAT identified by one RAT identifier is selected from the resident objects and used as the target cell suitable for residing. Optionally, the number of candidates is reduced based on the RAT identifier, and further, a suitable camping cell is selected or reselected from the reduced candidate based on the identity of the camping object. When narrowing down the candidates based on the RAT identification, the candidates obtained after narrowing down may include not only the resident object but also other candidates.

As a possible implementation manner, in response to that the configuration information includes priority information of the frequency point and/or the cell and/or the RAT, the UE performs selection or reselection of a target cell where the UE is suitable to camp on based on the configured priority information. Optionally, the UE may rank the priority information of the frequency points and/or the cells and/or the RATs, rank the priority information according to the priority information, and select a target cell suitable for residing from the candidate objects corresponding to the frequency points and/or the cells and/or the RATs to reside. In some implementations, the frequency point and/or the cell to which the dedicated uplink resource belongs and/or the priority of the RAT used may be higher, so that the UE can be instructed to select a suitable target cell to camp on from the cells configured with the dedicated uplink resource.

As another possible implementation manner, in response to that the configuration information includes an available time length of the priority information of the frequency point and/or the cell and/or the RAT, the UE needs to perform cell selection or reselection based on the identification information of the frequency point and/or the cell and/or the RAT and the priority information of the frequency point and/or the cell and/or the RAT within the available time length of the priority information. For example, the configuration information is counted from the received time, and when the available time length of the priority information of the frequency point and/or the cell and/or the RAT is reached, the priority information of the frequency point and/or the cell and/or the RAT may fail.

In some implementations, the UE performs selection or reselection of a suitable resident cell based on the identification information of the frequency point and the cell selection or reselection priority and/or the cell selection or reselection sub-priority corresponding to the frequency point priority information in the available duration of the frequency point priority information. In some implementations, the UE performs selection or reselection of a suitable camping cell based on the identification information of the cell and the cell selection or reselection priority and/or the 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 camped cell based on a cell selection or reselection priority and/or a cell selection or reselection sub-priority of a cell in the cell priority information within an available duration of the RAT priority information.

In each embodiment of the present application, a plurality of target cells suitable for camping may be selected for the UE from candidate objects corresponding to the UE for camping; and finally determining a target cell for residing according to other information.

Fig. 3 is a schematic flow chart of another cell selection or reselection method provided in this embodiment and executed by a UE. As shown in fig. 3, the cell selection or reselection method includes the following steps:

s301, receiving configuration information of an object to which an exclusive uplink resource belongs, wherein the configuration information indicates that the UE preferentially selects a cell suitable for residing from the object to which the exclusive uplink resource belongs.

For a specific description of step S301, reference may be made to the description of relevant contents in the above embodiments, and details are not repeated here.

S302, receiving configuration information of an exclusive object configured for the UE, wherein the exclusive object includes an exclusive frequency point and/or an exclusive cell, and the configuration information is sent by the network device.

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, the configuration information of one dedicated object may be additionally configured through an rrcreelease message. Wherein, the configuration information of the exclusive object comprises at least one of the following items:

identification information of at least part of the exclusive objects in the exclusive objects;

priority information of the dedicated object;

the available duration of the priority information of the dedicated object.

And S303, based on the configuration information of the object to which the exclusive uplink resource belongs, selecting or reselecting a proper resident cell.

For a specific description of step S303, reference may be made to the description of relevant contents in the above embodiments, and details are not described herein.

And S304, in response to the unavailability of the dedicated uplink resource, selecting or reselecting a suitable resident cell based on the configuration information of the dedicated object.

Optionally, in this embodiment of the application, the condition for determining that the dedicated uplink resource is no longer available includes at least one of:

the uplink transmission of the dedicated uplink resource is no longer synchronized, for example, the uplink transmission of the dedicated uplink resource CG-1 corresponds to the uplink synchronization timer being out of time, that is, the subframe or timeslot position of the uplink transmission is no longer aligned.

The use duration of the dedicated uplink resource exceeds the configured available duration. For example, the network device configures dedicated uplink resource CG-1 to the UE through the rrcreelease message, and configures the available duration of CG-1 to be 100ms. The UE starts a timer (e.g., CG-validity timer) after receiving the configuration information of the CG-1, sets the duration of the timer to be 100ms, and when the timer expires, the UE considers that the CG-1 is no longer available.

When the dedicated uplink resource is not available, the configuration information of the object to which the dedicated uplink resource belongs is correspondingly invalidated, that is, no longer available, in the embodiment of the present application, when the configuration information of the dedicated object is configured, the UE may select a target cell suitable for residing from the candidate objects for residing based on the configuration information of the dedicated object. Regarding the process of selecting a suitable resident target cell based on the configuration information of the dedicated object, the process is similar to the process of selecting a suitable resident target cell based on the configuration information of the object to which the dedicated uplink resource belongs in the above embodiment, and details are not repeated here.

It should be noted that, as shown in fig. 4, the configuration information of the dedicated object may include an available duration of the priority information of the dedicated object. As shown in fig. 4, the time t1 is a starting time of an available duration of priority information of an object in configuration information of an object to which an exclusive uplink resource belongs, the time t2 is an ending time of the available duration of the priority information of the object, and the time t2 is a starting time of a timer corresponding to the available duration of the priority information of the exclusive object and ends at the time t 3. And when the available time timer of the priority information of the exclusive object reaches the time t3, the UE considers that the priority information of the exclusive object is no longer available.

It should be noted that, if the network device does not configure the dedicated object and the configuration information of the dedicated object for the UE, the UE selects a target cell suitable for residing in for the UE from the candidate objects by using the priority information configured in the system information.

In the embodiment of the 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 are/is invalid, the UE selects or reselects a cell where the UE appropriately resides based on the configuration information of the dedicated object to acquire the cell where the UE appropriately resides, so that the UE can be always located in the cell where the UE appropriately resides, and thus high-quality service can be provided for the UE.

Fig. 5 is a schematic flow chart of another cell selection or reselection method provided in this embodiment and executed by a UE. As shown in fig. 5, the cell selection or reselection method includes the following steps:

s501, receiving configuration information of an object to which an exclusive uplink resource belongs, wherein the object to which the exclusive uplink resource belongs includes a frequency point and/or a cell to which the exclusive uplink resource belongs.

For specific description of step S501, reference may be made to the description of relevant contents in the above embodiments, and details are not repeated here.

And S502, based on the configuration information of the object to which the exclusive uplink resource belongs, selecting or reselecting a proper resident cell.

For a specific description of step S502, reference may be made to the description of relevant contents in the above embodiments, and details are not repeated here.

S503, in response to the exclusive uplink resource is unavailable, deleting or suspending the configuration information and/or the exclusive uplink resource of the object to which the exclusive uplink resource belongs.

For the condition for determining that the dedicated uplink resource is no longer available, reference may be made to the description of the related contents in the above embodiments, which is not described herein again.

When the dedicated uplink resource is not available, the configuration information of the object to which the dedicated uplink resource belongs may also be invalid, i.e., no longer available, and in this embodiment, the UE may delete or suspend the configuration information of the dedicated uplink resource and/or the object to which the uplink resource belongs. For example, the UE receives, in an rrcreelease message, a CG-1 resource belonging to a frequency point-1 or a cell-1 and configured by the network device, and when uplink transmission of the CG-1 resource is no longer synchronous, it indicates that the CG-1 resource is no longer available, optionally, the UE deletes or suspends the configuration information of the frequency point-1 or the cell-1 corresponding to the CG-1 resource, or the UE deletes or suspends both the configuration information of the frequency point-1 or the cell-1 corresponding to the CG-1 resource and the CG-1 resource.

In the embodiment of the 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 fails, the UE deletes or suspends the configuration information of the object to which the dedicated uplink resource belongs and/or the dedicated uplink resource, so as to release the resource conveniently.

Fig. 6 is a schematic flow chart of another cell selection or reselection method provided in this embodiment and executed by a network device. As shown in fig. 6, the cell selection or reselection method includes the following steps:

s601, sending configuration information of an object to which the dedicated uplink resource belongs to the UE, wherein the configuration information is used for indicating the UE to select or reselect a suitable resident cell based on the configuration information, and the object to which the dedicated uplink resource belongs comprises a frequency point to which the dedicated uplink resource belongs and/or a cell to which the dedicated uplink resource belongs.

In this embodiment, the dedicated uplink resource of the UE may include: the resource on the PUSCH, the resource on the PUCCH, for example, the dedicated uplink resource on the PUSCH may be a PUR resource, or a CG resource.

Optionally, the dedicated uplink resource of the UE may include configuration by the network device, or may be determined in a predetermined manner.

In this embodiment, the network device may send configuration information of an object to which the dedicated uplink resource belongs to the UE. For example, the network device may send the configuration information of the dedicated uplink resource belonging object to the UE in the rrcreelease message, or the network device may send the configuration information of the dedicated uplink resource belonging object to the UE in some configuration signaling. In some implementations, the network device may send the UE the configuration information of the object to which the dedicated uplink resource belongs while sending the dedicated uplink resource to the UE. In some implementations, the network device may also send the configuration information of the object to which the dedicated uplink resource belongs to the UE after sending the dedicated uplink resource to the UE.

Optionally, the network device may configure dedicated uplink resources for the UE on frequency point-1 or cell-1. Or, configuring exclusive uplink resources for the UE on the frequency point-1 or the cell-1 by protocol agreement in advance.

In the embodiment of the present application, after the configuration information of the object to which the dedicated uplink resource belongs is obtained, a cell suitable for residing can be selected from candidate objects of the UE based on the configuration information. The candidate objects at least include an object to which the dedicated uplink resource belongs, that is, a frequency point and/or a cell to which the dedicated uplink resource belongs. In some implementations, the candidate object may further include a part of frequency points and/or cells not configured with the dedicated uplink resource. Alternatively, the UE may select a cell suitable for camping from the candidate objects based on the signal quality of the candidate objects, the area locations of the candidate objects, the access control information, and the like.

In some implementations, the priority of the partial candidates and/or the validity duration of the configuration priority may be included in the configuration information. Optionally, the priority of the object to which the partially dedicated uplink resource belongs or the RAT priority used may be configured in the configuration information. In some implementations, the configuration information includes a priority of an object to which the dedicated uplink resource belongs, or a priority of a RAT employed by the object to which the dedicated uplink resource belongs. Optionally, the configuration information may include not only the priority of the object to which the part of dedicated uplink resources belong or the priority of the adopted RAT, but also the priority of the part of candidate objects or the priority of the adopted RAT. In the embodiment of the present application, the information carried by the configuration information is not limited.

In some implementations, in a case that all the candidate objects are configured with priorities, if the priority of the object where the dedicated uplink resource is located is higher, the UE selects a cell where the UE appropriately resides from the candidate objects, that is, the candidate frequency points and/or the candidate cells, based on the priority, so that the UE can access the cell where the UE appropriately resides. In some implementations, the object where the dedicated uplink resource is located is configured with a priority, and the frequency point or cell where the dedicated uplink resource is not configured with a priority, which similarly enables the frequency point or cell where the dedicated uplink resource is located to be preferentially selected by the UE. The configuration information of the object to which the dedicated uplink resource belongs in the two implementations can indicate that the UE preferentially selects a cell suitable for residing from the object to which the dedicated uplink resource belongs, so that the UE resides in the cell suitable for residing, and the UE can reside in a frequency point and/or a cell configured with the dedicated uplink resource as much as possible, so that the UE can use the dedicated uplink resource to send data to the network device.

And the configuration information can indicate that the UE preferentially selects a cell suitable for residing from the object to which the exclusive uplink resource belongs to facilitate the UE to access the cell suitable for residing, so that the frequency point or the cell where the exclusive uplink resource exists has a chance of being preferentially selected by the UE, the UE can further reside in the frequency point or the cell configured with the exclusive uplink resource as much as possible, and waste of the exclusive uplink resource reserved for the UE is prevented.
