detailed description

The technical solutions in the embodiments of the present disclosure will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present disclosure. Obviously, the described embodiments are part of the embodiments of the present disclosure, but not all of the embodiments. Based on the embodiments in the present disclosure, all other embodiments obtained by a person of ordinary skill in the art without making creative efforts fall within the protection scope of the present disclosure.

The term "comprising" and any variants thereof in the description and claims of this application are intended to cover non-exclusive inclusions, for example, a process, method, system, product, or device containing a series of steps or units need not be limited to clear Those steps or units are listed explicitly, but may include other steps or units not explicitly listed or inherent to these processes, methods, products, or equipment. In addition, the use of "and / or" in the specification and in the claims indicates at least one of the connected objects, such as A and / or B, which means that there are three cases of A alone, B alone, and A and B.

In the embodiments of the present disclosure, words such as "exemplary" or "for example" are used as examples, illustrations or illustrations. Any embodiment or design described as "exemplary" or "for example" in the embodiments of the present disclosure should not be construed as more preferred or advantageous over other embodiments or designs. Rather, the use of words such as "exemplary" or "for example" is intended to present related concepts in a concrete manner.

When the terminal is powered on, it needs to select the initial cell. During the initial cell selection process, the terminal scans all the radio frequency channels (RF channels) one by one according to its own capabilities to find a suitable cell. At each scanning carrier frequency, the terminal only needs to search for the cell with the strongest signal quality. Once a suitable cell is found, the cell is selected for camping.

When the terminal traverses from one cell to another cell in a non-connected state, the terminal needs to perform cell reselection. In the cell reselection process in the related technology, the terminal sequentially evaluates whether or not each frequency point has a suitable reselection target cell based on the priority order of the frequency points provided by the network-side device. A suitable cell can be used as a target cell for reselection. For different frequency points, they can be configured with the same frequency point priority or with different frequency point priorities. The suitable cell refers to a cell where the terminal can camp and obtain normal services. The non-connected state includes an idle state or an inactive state.

For example, in the above cell reselection process, when a terminal camps on a serving cell, if a cell at a frequency of a higher priority NR or other RAT satisfies a period of TreselectionRAT (that is, a cell reselection timer) The signal quality of the cell within Squal> threshold ThreshX, HighQ, the terminal may initiate a reselection process to a cell at a frequency point of a higher priority NR or other RAT; or, if a higher priority NR exists Or the cells at other RAT frequencies meet the signal strength Srxlev> threshold ThreshX, HighP within a period of TreselectionRAT, and the terminal has camped on the current serving cell for more than one second, the terminal can initiate to a higher priority NR or Cell reselection process at other RAT frequencies.

In the related art, the cell reselection priority may be carried in an RRCRelease message, or may be carried in a system message. The cell reselection priority carried in the RRCRelease message is a special priority. If the RRCRelease message does not carry the cell reselection priority, the terminal takes the cell priority broadcasted in the system message as the standard. In related technologies, cell reselection priorities are 0-7, where 0 represents the lowest priority and 7 represents the highest priority.

In related technologies, network-side devices may assign priorities of frequency points based on load conditions at different frequency points to achieve the purpose of load balancing. However, the way of assigning the priorities of frequency points based on the load situation may cause the target cell reselected by the terminal to not adapt well to the needs of the terminal.

Therefore, the embodiment of the present disclosure aims to provide a cell reselection method, so that the cell reselection mechanism of the terminal does not only follow the frequency point priority indicated by the network-side device, but may introduce other cell reselection mechanisms. For example, for service-based cell reselection, the terminal will tend to reside on the frequency point where it provides services of interest; cell reselection based on access network notification area (RAN-based Notification Area, RNA), inactive The terminal may preferentially select a cell belonging to the same RNA; and so on.

The cell reselection system, the cell reselection method, the terminal, and the network-side device according to the embodiments of the present disclosure are specifically described below.

The cell reselection method provided in the embodiments of the present disclosure can be applied to a wireless communication system. The wireless communication system may be a 5G New Radio (NR) system, or a Long Term Evolution (LTE) system, or an Evolved Long Term Evolution (eLTE) system, or a subsequent evolved communication system.

FIG. 1 is a structural diagram of a cell reselection system according to an embodiment of the present disclosure. As shown in FIG. 1, the system includes a terminal (User Equipment) 11 and a network-side device 12. The terminal 11 may be a mobile communication terminal. For example: it can be a mobile phone, a tablet (Personal Computer), a laptop (Laptop Computer), a personal digital assistant (PDA), a mobile Internet device (Mobile Internet Device (MID), or a wearable device ( Wearable (Device) and other devices. It should be noted that the specific type of the terminal 11 is not limited in the embodiments of the present disclosure. The above network-side device 12 may be a 5G network-side device (for example, gNB, 5G, NR, NB), or may be a 4G network-side device (for example, eNB), or may be a 3G network-side device (for example, NB), or subsequent evolution The network-side device in the communication system, etc. It should be noted that the specific type of the network-side device 12 is not limited in the embodiments of the present disclosure.

An embodiment of the present disclosure provides a cell reselection system as shown in FIG. 1, and provides a cell reselection method applied to the cell reselection system, as follows:

Cell reselection is performed by using a cell reselection target priority. The cell reselection target priority is: using a target modification parameter to modify a cell reselection priority sent by a network-side device to obtain the modified priority.

The above-mentioned target modification parameters may be agreed through a protocol or may be indicated by a network-side device, which is not limited in the embodiment of the present disclosure. The above target modification parameters can be used by the terminal to modify the cell reselection priority sent by the network-side device.

It should be noted that the embodiment of the present disclosure provides a possibility that the terminal can modify the cell reselection priority. Whether the terminal uses the target modification parameter to modify the cell reselection priority can be based on its own requirements, or can be based on Make decisions in its current scenario.

In the related art, during the cell reselection process, the terminal needs to comply with the cell reselection priority indicated by the network-side device. In the embodiment of the present disclosure, the terminal can use the target modification parameter to modify the cell reselection priority and use the modification. The obtained target priority of the cell is then used for cell reselection. It can be seen that the terminal can reselect the target cell more flexibly, and the target cell reselected by the terminal can better meet the needs of the terminal, which is conducive to improving the communication performance of the terminal.

FIG. 2 is a flowchart of a cell reselection method according to an embodiment of the present disclosure. As shown in FIG. 2, the cell reselection method, which is applied to a terminal, includes the following steps:

Step 201: Use the cell reselection target priority to perform cell reselection. The cell reselection target priority is to use the target modification parameter to modify the cell reselection priority sent by the network-side device to obtain the modified priority. .

The network-side device may send the cell reselection priority to the terminal in any of the following ways:

Radio resource control (Radio Resource Control, RRC) signaling, such as an RRCRelease message;

System message broadcasts, such as System Message Block Type 2 (System Information Block Type 2, SIB2), System Message Block Type 4 (System Information Block Type 4, SIB4), and System Message Block Type 5 (System Information Block Type 5, SIB5)

The cell reselection priority can also be inherited from other radio access technologies that are different from the current radio access technology. For example, when the terminal is in the eLTE system, the network-side device sends the cell reselection priority to the terminal through RRC signaling. When switching from the eLTE system to the 5G NR system, the terminal can continue to use the cell to reselect the priority.

The above-mentioned manner in which the network-side device sends the cell reselection priority may use related technologies, and is not described in detail herein.

In the embodiment of the present disclosure, the target modification parameter may be used by the terminal for modifying (including reducing or enlarging) the cell reselection priority. Therefore, the modified parameter may also be referred to as a cell reselection priority scaling factor. The target modification parameter may be a value for performing an operation with the cell reselection priority, and the value may be any integer or decimal from 0 to 7. The target modification parameter may also be a function of the cell reselection priority.

The foregoing use of the target modification parameter to modify the cell reselection priority sent by the network-side device can be understood as using the target modification parameter to perform an operation on the cell reselection priority sent by the network-side device. The operation may include at least one of the following: an addition operation, a multiplication operation, a division operation, and a subtraction operation.

The above target modification parameters may be agreed through a protocol or may be indicated by a network-side device, which is not limited in the embodiment of the present disclosure.

The above target modification parameters may be selected from a plurality of modification parameters corresponding to different effective conditions, and the modification parameters corresponding to the currently effective effective conditions.

For example, a plurality of modification parameters corresponding to different effective conditions may be agreed through the agreement, and the terminal selects a target modification parameter corresponding to the current scene (or, currently effective effective conditions) according to the scene in which the terminal is currently located. It is also possible to issue modification parameters corresponding to different effective conditions through a network-side device, and the terminal selects a target modification parameter corresponding to the current scene (or, currently effective effective conditions) according to the scene in which the terminal is currently located. It may also be that after obtaining the reference information of the terminal, the network-side device selects a target modification parameter suitable for the terminal from a plurality of modification parameters corresponding to different effective conditions according to the reference information of the terminal, and sends the target modification parameter to terminal.

In addition, after acquiring the reference information of the terminal, the network-side device can also directly configure the target modification parameters for the terminal according to the reference information of the terminal, without selecting from multiple modification parameters.

Optionally, before the cell reselection using the cell reselection target priority, the method further includes:

Receiving instruction information from a network-side device, where the instruction information is used to instruct the target to modify a parameter.

In this embodiment, the instruction information indicating the target modification parameter is sent to the terminal through the network-side device.

Further, the foregoing indication information may be transmitted through RRC signaling (such as an RRCRelease message); or,

The indication information may be transmitted via system message broadcast (such as SIB2, SIB4, SIB5); or

The instruction information may be inherited from other wireless access technologies different from the current wireless access technology. For example, when the terminal is in the eLTE system, the network-side device sends the instruction information to the terminal through RRC signaling. When the terminal switches from the eLTE system to In the 5G NR system, the terminal can continue to use the instruction information.

Optionally, before the receiving the instruction information from the network-side device, the method further includes:

Sending parameter determination reference information to the network-side device;

The target modification parameter is a modification parameter determined by the network-side device according to the parameter determination reference information.

The above-mentioned parameter determination reference information can be understood as reference information of the terminal itself (for example, information such as a scene where the terminal is currently located), and the reference information is used by a network-side device to determine a target modification parameter.

In this embodiment, the network-side device may determine the reference information based on the parameters of the terminal, and configure a target modification parameter for the terminal. In this case, the target modification parameter is determined based on the terminal's parameter determination reference information. Therefore, the target modification parameter is applicable to the terminal, and the target modification parameter can be understood as a modification parameter corresponding to a currently valid effective condition. The terminal may use the target modification parameter to modify the cell reselection priority to obtain the cell reselection target priority, and use the cell reselection target priority to perform cell reselection.

Optionally, the parameter determination reference information of the terminal includes at least one of the following:

The RRC state of the terminal, such as an RRC_idle state or an RRC_inactive state;

Whether the terminal is in an inactive state, and the number of times of performing RAN-based Notification Area Update (RNAU) within a preset time exceeds a preset threshold;

Frequency points corresponding to services supported by the terminal;

The speed of the terminal;

The speed state of the terminal, such as a high speed state, a medium speed state, or a low speed state.

After the terminal sends the foregoing parameter determination reference information to the network-side device, the network-side device may determine the target modification parameter applicable to the terminal according to the parameter determination reference information.

Optionally, the indication information further indicates at least one of the following information:

The effective time of the target modification parameter;

Effective conditions of the target modification parameter.

If the effective time of the target modification parameter is indicated in the instruction information, the terminal may use the target modification parameter within the effective time of the target modification parameter. If the effective time of the target modification parameter expires, the network-side device may need to reconfigure the target modification parameter for the terminal.

If the effective condition of the modified parameter is indicated in the instruction information, the terminal may select a target to modify the parameter according to the scene in which the terminal is currently located. That is, the target modification parameter is a modification parameter corresponding to the currently valid effective condition among the modified parameters, and the effective condition of the target modified parameter matches the scenario in which the terminal is currently located.

Optionally, the effective condition of the target modification parameter is described using at least one of the following information:

The RRC state of the terminal;

Support information of the terminal for service-based cell reselection;

Support information of the terminal for RNA-based cell reselection;

Support information of the terminal for speed-based cell reselection;

The terminal's support information for cell reselection based on speed status.

Wherein, the terminal's support information for service-based cell reselection includes the two cases where the terminal supports service-based cell reselection and the terminal does not support service-based cell reselection. If the terminal supports service-based cell reselection, the terminal may use the target modification parameter to modify the cell reselection priority of the frequency point based on the frequency point at which the service of interest is located to obtain the cell at the frequency point. Reselect target priority.

Wherein, the terminal's support information for RNA-based cell reselection includes the two cases where the terminal supports RNA reselection and the terminal does not support RNA reselection. If the terminal supports cell reselection of RNA, the terminal in the inactive state may use the target modification parameter to perform cell reselection priority on the frequency based on the frequency of the cell in the same RNA as the serving cell. Modify to get the cell reselection target priority at this frequency.

Wherein, the terminal's support information for cell reselection based on speed or speed state includes two cases: the terminal supports cell reselection for speed or speed state, and the terminal does not support cell reselection for speed or speed state. If the terminal supports cell reselection at a speed or speed state, the terminal at a different speed or speed state may use the target modification parameter to reselect the cell at that frequency point based on which frequency point the cell it needs to access is at The priority is modified to obtain the cell reselection target priority of the frequency point.

As described above, the network-side device may send the instruction information indicating the target modification parameter, and the target modification parameter may be determined through the parameter determination reference information sent by the terminal, so that the target modification parameter is applicable to the terminal. On the other hand, the target modification parameter can also be determined through terminal selection. In this mode, the instruction information sent by the network-side device may include multiple modification parameters and the effective conditions corresponding to each modification parameter. After receiving the instruction information, the terminal may modify the parameters according to its current scene and the instruction information. For the corresponding effective conditions, select the target modification parameter from the modification parameters in the instruction information.

Optionally, the effective condition of the modification parameter in the indication information is described using at least one of the following information:

RRC status of the terminal;

Support information of the terminal for service-based cell reselection;

Support information of the terminal for RNA-based cell reselection;

Support information of the terminal for speed-based cell reselection;

The terminal's support information for cell reselection based on speed status.

Wherein, if the terminal supports service-based cell reselection, the terminal may select a modification parameter from the network-side device instruction to modify the parameter, and the target may modify the parameter that is valid when the terminal supports service-based cell reselection, and may be based on which service it is interested in. At the frequency point, the cell reselection priority of the frequency point is modified by using the target modification parameter to obtain the cell reselection target priority of the frequency point.

If the terminal supports RNA-based cell reselection, the inactive terminal can select a target modification parameter that is valid when the terminal supports RNA-based cell reselection from the modification parameters indicated by the network-side device, and can serve based on its own At which frequency of a cell in the same RNA is the cell, use the target modification parameter to modify the cell reselection priority of the frequency to obtain the cell reselection target priority of the frequency.

If the terminal supports cell reselection based on speed or speed status, the terminal may select a target modification parameter that is valid when the terminal supports cell reselection based on speed or speed status from the modification parameters indicated by the network-side device, at a different speed or speed The terminal in the state may modify the cell reselection priority of the frequency point based on the frequency point of the cell to which the user needs to access to obtain the cell reselection target priority of the frequency point.

In the embodiment of the present disclosure, when the terminal meets the measurement condition and the reselection condition, the terminal may perform cell reselection by using the cell reselection target priority.

The reselection condition means that the terminal needs to select a cell with a frequency point with a different frequency point priority for reselection according to the satisfaction of different conditions. For example:

If the threshold threshinging LowQ parameter is broadcast in the system, and the terminal has camped on the current target cell for more than 1 second, then if there is a cell with a high priority NR / LTE frequency, the signal quality Squal> ThreshX, HighQ within the time interval TreselectionRAT , The terminal will initiate a reselection to the cell at a high priority frequency.

If the system does not broadcast the thresholdServingLowQ parameter, but the terminal has been camped on the current target cell for more than 1 second, and the cell at the high priority frequency meets the signal strength Srxlev> ThreshX, HighP within the time interval TreselectionRAT, the terminal will initiate a high priority Reselection of the cell at the frequency point.

If the threshServingLowQ parameter is broadcast in the system and the terminal has camped on the current target cell for more than 1 second, then if the serving cell Squal <ThreshServing, LowQ is satisfied within the time interval TreselectionRAT and there is a cell Squal on the low priority NR / LTE frequency > ThreshX, LowQ, the terminal will initiate a reselection to the cell at a low priority frequency.

If the system does not broadcast the thresholdServingLowQ parameter, but the terminal has camped on the current target cell for more than 1 second, and the serving cell Srxlev <ThreshServing, LowP is satisfied within the time interval TreselectionRAT, and there is a cell Srxlev> ThreshX on the low priority NR / LTE frequency LowP, the terminal will initiate reselection to the cell at the low priority frequency.

For cell reselection at the same priority frequency, the R criterion for cell reselection at the same frequency is directly performed.

The above-mentioned high-priority frequency points, the same-priority frequency points, and the low-priority frequency points are obtained after comparing the cell reselection target priority with the frequency priority of the serving cell. Among them, frequencies higher than the frequency priority of the serving cell are high priority frequencies, frequencies lower than the frequency priority of the serving cell are low priority frequencies, and the frequency priority of the serving cell is The same frequency points are the same priority frequency points.

In the embodiment of the present disclosure, the terminal may use the target modification parameter to modify the cell reselection priority, and use the modified cell retargeting priority to perform cell reselection. It can be seen that the terminal can reselect the target cell more flexibly, and the target cell reselected by the terminal can better meet the needs of the terminal, which is conducive to improving the communication performance of the terminal.
