Description
Technical Field
The present application relates to the field of wireless communications technologies, and in particular, to a cell reselection method, an electronic device, and a computer storage medium.
Background
In order to reduce the burden on the public network, the 5G spectrum used by the industrial internet may be a public network 5G spectrum, or may use an unlicensed network spectrum or a public network spectrum. Independent networking is carried out by using a 5G NR-U (5G New Radio in Unlicensed Spectrum) Unlicensed Spectrum, so that the repeated utilization rate of Spectrum resources can be improved. In addition, the 5G NR-U network is generally a self-established network for enterprise Users, and is mainly applied to a production scenario, and the coverage of 5G in the field of production and manufacturing is generally fixed, for example, the network coverage is generally fixed in a factory area, and the working range of a terminal UE (Users Experience) is also in the more fixed area.
However, in the actual process of deploying the unlicensed spectrum, unlicensed spectrum networks of different operators may overlap, and if spectrum coordination is not performed between the unlicensed spectrum networks of different operators, cells belonging to different Public Land Mobile Networks (PLMNs) may exist at the same frequency point, so that a cell with a strongest unlicensed frequency band signal measured by the terminal UE during reselection may not belong to a registered PLMN thereof, and therefore, even if the cell satisfies an S criterion (cell selection criterion), cell reselection may be performed, but reselection may fail due to PLMN mismatch. While PLMN Information is broadcast in a system Information block SIB1 (Scheduling Unit-1), in order to identify whether a cell belongs to a registered PLMN, the terminal UE needs to acquire a Management Information Base MIB (Management Information Base) and SIB1 of more than one cell in the NR-U, which may significantly increase the power consumption of the terminal UE and delay the cell reselection speed. Meanwhile, as the measurement capability of the terminal UE is limited (for example, the number of co-frequency cells and the number of inter-frequency cells measurable by some terminal UEs are 8 and 4), detecting the cells of the unregistered PLMN may also cause the measurement capability of the terminal UE to be limited, thereby greatly increasing the time delay and power consumption of cell reselection.

Detailed Description
The technical solutions in the embodiments of the present application will be described in detail and clearly with reference to the accompanying drawings. It is to be understood that the embodiments described are only a few embodiments of the present invention, and not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention. In the embodiment of the application, the acquisition, storage, use, processing and the like of the data all conform to relevant regulations of national laws and regulations.
In order to reduce the burden on the public network, the 5G spectrum used by the industrial internet may be a public network 5G spectrum, or may use an unlicensed network spectrum or a public network spectrum. Independent networking is carried out by using a 5G NR-U (5G New Radio in Unlicensed Spectrum) Unlicensed Spectrum, so that the repeated utilization rate of Spectrum resources can be improved. In addition, the 5G NR-U network is generally a self-established network for enterprise Users, and is mainly applied to a production scenario, and the coverage of 5G in the field of production and manufacturing is generally fixed, for example, the network coverage is generally fixed in a factory area, and the working range of a terminal UE (Users Experience) is also in the more fixed area.
However, in the actual process of deploying the unlicensed spectrum, unlicensed spectrum networks of different operators may overlap, and if spectrum coordination is not performed between the unlicensed spectrum networks of different operators, cells belonging to different Public Land Mobile Networks (PLMNs) may exist at the same frequency point, so that a cell with a strongest unlicensed frequency band signal measured by the terminal UE during reselection may not belong to a registered PLMN thereof, and therefore, even if the cell satisfies an S criterion (cell selection criterion), cell reselection may be performed, but reselection may fail due to PLMN mismatch. While PLMN Information is broadcast in a system Information block SIB1 (Scheduling Unit-1), in order to identify whether a cell belongs to a registered PLMN, the terminal UE needs to acquire a Management Information Base MIB (Management Information Base) and SIB1 of more than one cell in the NR-U, which may significantly increase the power consumption of the terminal UE and delay the cell reselection speed. Meanwhile, due to the fact that the measurement capability of the terminal UE is limited (for example, the number of co-frequency cells measurable by some terminal UEs is 8, and the number of inter-frequency cells measurable by some terminal UEs is 4), the detection of the cells of the unregistered PLMN can also cause the limitation of the measurement capability of the terminal UE, and the time delay of cell reselection, power consumption and the like are greatly increased.
As shown in fig. 1, a schematic diagram of an application environment provided according to an embodiment of the present application is applied to a 5GNR-U network, where the 5G NR-U network includes two different PLMNs, which are equivalent to belonging to two different operators, namely a 5G NR-U network PLMN1 and a 5G NR-U network PLMN1, when a user equipment UE currently resides in a cell 1 or a cell 2 and is in a standby state. A cell 2 or a cell 1 is obtained through reselection measurement, where the cell 1 and the cell 2 belong to the same frequency point but belong to different PLMNs (this is possible due to the openness of an unlicensed network), and in this case, when a reselection condition is satisfied to perform cell reselection, reselection failure may be caused because the two cells belong to different PLMNs. In order to ensure successful cell reselection, SIB1 reception is completed or relevant field information needs to be added to the MIB (protocol modification is required), which increases the complexity of reselection.
In a first aspect, the present application provides a cell reselection method, and a flowchart is shown in fig. 2, where the method includes:
In one or more possible embodiments, after being powered on, the UE residing in the 5G NR-U network reads a system message for cell attachment, and reads a system message for cell selection and reselection in an idle mode, where the system message is downlink broadcast information periodically transmitted by a base station, and basically provides all details required for accessing the network, such as a system frame number, a system bandwidth, a PLMN, a cell selection and reselection threshold, and the like; and determining whether a cell meeting reselection conditions exists according to a measurement result obtained by the system message. Step 202, if there is at least one cell satisfying the reselection condition, receiving a system information block SIB1 message of the cell satisfying the reselection condition.
In one or more possible embodiments, if there is one cell satisfying the reselection condition, the SIB1 message of the one cell satisfying the reselection condition is received, and if there are multiple cells satisfying the reselection condition, the SIB1 messages of all the cells satisfying the reselection condition need to be received, and the multiple cells satisfying the reselection condition need to be prioritized.
And step 203, if the cell meeting the reselection condition does not exist, performing next new air interface NR measurement according to the indication of the network side.
In one or more possible embodiments, after the NR measurement, if no cell satisfying the reselection condition is found, the NR measurement needs to be performed again according to the indication of the network side, and the cell reselection process cannot be performed until at least one cell satisfying the reselection condition is found.
And step 204, judging whether the cell meeting the reselection condition and the current UE belong to the same operator or not according to the public land mobile network PLMN information in the SIB1 message.
In one or more possible embodiments, the PLMN is a pronoun of the mobile communication network. Specifically to our country, each mobile operator's network calculates a PLMN, and thus the networks for china mobile, china unicom and china telecommunications are different PLMNs. The PLMN information is composed of an MCC mobile country code and an MNC mobile network code, for example, PLMNs of the chinese mobile GSM are: 46000 (MCC: 460, MNC 00), the PLMN country code MCC of China Unicom GSM is 460, and the network code MNC is 01:46001. in order to make the user know the located PLMN, each PLMN should have an explicit identifier (number) and be broadcasted by the base station as system information, so that the terminal under the base station can receive the system information, and therefore, by comparing the MCC mobile country code and MNC mobile network code in the current PLMN of the UE with those in the received PLMN, it can be determined whether the PLMN belongs to the same operator.
In step 205, if any cell satisfying the reselection condition and the current UE belong to the same operator, reselecting the cell satisfying the reselection condition.
According to the cell reselection method provided by the application, for the user terminal UE residing in the 5G NR-U network, due to the fact that the unlicensed spectrum networks of different operators may overlap in the actual deployment process of the unlicensed spectrum, if spectrum coordination is not performed among the unlicensed spectrum networks of different operators, cells belonging to different PLMNs may exist under the same frequency point, and therefore the cell with the strongest unlicensed frequency band signal measured by the terminal UE during reselection may not belong to the registered PLMN of the cell, cell reselection can be performed even if the cell meets the S criterion, reselection failure is caused due to the fact that the PLMNs are not matched, and based on the cell reselection method provided by the application, the problem of cell reselection failure can be avoided without changing protocols, and user experience is optimized.
In one or more possible embodiments, if there is a cell satisfying the reselection condition, as shown in fig. 3, the method includes:
in one or more possible embodiments, if there are multiple cells satisfying the reselection condition, as shown in fig. 4, the method includes:
in one or more possible embodiments, if at least one of the cells satisfying the reselection condition belongs to the same operator as the current UE, it indicates that the cell reselection is successful, as shown in fig. 5:
in step 503, more than one cell satisfying the reselection condition among the cells satisfying the reselection condition and the current UE belong to the same operator, and the current UE is reselected from the current cell to any one of the more than one cell satisfying the reselection condition.
According to the cell reselection method provided by the application, aiming at the user terminal UE residing in the 5G NR-U network, the problem of cell reselection failure can be avoided without changing a protocol, and user experience is optimized.
In one or more possible embodiments, a system information block SIB1 message of a cell satisfying a reselection condition is received, and a flowchart is shown in fig. 6, where the method includes:
In one or more possible embodiments, a new forbidden list is established or whether each cell meeting reselection conditions is in the forbidden list is checked according to the established forbidden list;
as shown in fig. 7, the new forbidden list is schematic, and each entry in the list is empty; as shown in fig. 14, a flow chart for the forbidden list being empty;
1401, establishing a new forbidden list;
as shown in fig. 8, the forbidden list is schematic, and the forbidden list includes two cells satisfying the screening condition; as shown in fig. 15, a flow diagram for a forbidden list not being empty;
1503, each cell meeting the reselection condition and a cell forbidden to be reselected in the forbidden selection list have an overlapped part, and the cells meeting the reselection condition of the overlapped part are screened out;
step 1504, receiving the SIB1 message of the cell which is not screened and meets the reselection condition;
and when the step that the proceeding list is empty or not empty is completed, the following steps of reselecting are continuously executed.
In one or more possible embodiments, it is determined that all cells meeting the reselection condition coincide with cells in the reselection forbidden list according to the reselection forbidden list, and it is not necessary to receive SIB1 messages of all cells meeting the reselection condition, which indicates that the current cell reselection fails, and the cell reselection is stopped and resides in the current cell.
In one or more possible embodiments, after determining whether the cell satisfying the reselection condition and the current UE belong to the same operator, the method further includes adding the cell satisfying the reselection condition, which does not belong to the same operator as the current UE, to the reselection list to update the reselection list.
After the forbidden list is learned and updated for a period of time, the forbidden list can be directly screened in a 5G NR-U network in a fixed range without changing protocols, the problem of repeatedly receiving invalid SIB1 is avoided, reselection efficiency is improved, the speed of cell reselection can be greatly improved, power consumption is improved, and user experience is optimized.
In one or more possible embodiments, if there is at least one cell that satisfies the reselection condition, receiving a system information block SIB1 message of the cell that satisfies the reselection condition, where a flowchart is shown in fig. 9 and includes:
In one or more possible embodiments, if the plurality of cells satisfying the reselection condition perform at least steps 601 to 603, then at least one cell satisfying the reselection condition is reduced, the remaining other cells satisfying the reselection condition are prioritized, and the system information block SIB1 messages of the cells satisfying the reselection condition are sequentially received according to the priority order.
In one or more possible embodiments, if there is any one of the cells satisfying the reselection condition and the current UE belonging to the same operator, reselecting the cell satisfying the reselection condition, where the flowchart is shown in fig. 11 and includes:
and step 1102, reselecting the cell meeting the reselection condition with the highest priority according to the sequence of the priorities.
In one or more possible embodiments, if there is any one of the cells satisfying the reselection condition and the current UE belonging to the same operator, reselecting the cell satisfying the reselection condition, where the flowchart is shown in fig. 12 and includes:
In one or more possible embodiments, before the step of performing a new air interface NR measurement according to an indication of a network side and determining whether there is a cell satisfying a reselection condition according to a measurement result, the method further includes: clearing the forbidden list if the current UE is determined not to reside in the 5G NR-U network or the current UE is determined to replace the operator. The present application is applied to a UE residing in the 5G NR-U network, for example, when the UE registers in a public network, the forbidden list needs to be cleared, or the established forbidden list is directed to a connected network, when the UE changes an operator to a telecommunication or mobile network, the forbidden list needs to be cleared, and different forbidden lists are established for different operators.
According to a cell reselection method provided by the present application, as shown in fig. 13, the flowchart is applied to a user equipment UE residing in a 5G NR-U network, and in a fixed range, in step 1301, the UE performs a new air interface NR measurement according to an indication of a network side, in step 1302, determines whether a cell satisfying a reselection condition exists according to a measurement result, if no cell satisfying the reselection condition exists, the step 1301 is returned, if yes, in step 1303, the cells satisfying the reselection condition are sorted by priority, in step 1304, it is checked whether each cell satisfying the reselection condition is in a reselection forbidden list, if the forbidden list is empty, in step 1305, an SIB1 message of the cell satisfying the reselection condition is received, in step 1306, it is determined whether the current UE belongs to the same operator according to PLMN information in the SIB1 message, if yes, in step 1307, any cell satisfying the reselection condition is reselected, if not, in step 1308, the cell satisfying the reselection condition is added to the reselection list, in step 1309, if there is a cell satisfying the reselection condition, it is checked whether there is a cell, and if there is no cell satisfying the reselection condition is a cell is reselected, the reselection condition is returned 1308; if so, step 1310, prioritizing the remaining other cells meeting the reselection condition, step 1311, checking whether the cells meeting the reselection condition are in the forbidden list according to the priority order, step 1312, judging that the cell meeting the reselection condition with the highest priority is in the forbidden list, not receiving the SIB1 message of the cell meeting the reselection condition with the highest priority, and stopping the reselection to the cell meeting the reselection condition with the highest priority; receiving an SIB1 message of a cell of the secondary priority, repeating the steps 1305 to 1312, and finishing judgment of all cells meeting reselection conditions; if the forbidden list is not empty, executing step 1311, repeating other steps, and determining all cells meeting the reselection condition; if any cell meeting the reselection condition and the current UE belong to the same operator, reselecting the cell meeting the reselection condition, and if the cell meeting the reselection condition and the current UE do not belong to the same operator, indicating that reselection fails.
