Description
Technical Field
The present invention relates to a mobile communication technology, and in particular, to a method for a mobile terminal to access a cell.
Background
3GPP (3 rd Generation Partnership Project, third Generation partnership project) is an internationalized Mobile communication standardization organization. The 3GPP R17 (release 17) standard is formally frozen at month 6 of 2022.
A RedCap (Reduced Capability, reduced performance) terminal is defined in the 3gpp r17 freeze standard. The RedCap terminal reduces complexity by reducing terminal air interface capabilities, such as antenna capabilities, system bandwidth, peak rate, etc., to meet the requirements for reducing terminal cost, size, and power consumption. In other words, redCap is a lightweight, low cost, low power consumption 5G terminal technology.
The 5G network has the advantages of large bandwidth and high uplink and downlink speed. With the large-scale development of the RedCap technology, the number of terminals in the 5G cell may greatly increase, which results in limited bandwidth allocated to each mobile terminal, and thus cannot satisfy some scenes with high requirements on rate, such as games, videos, and the like.
Disclosure of Invention
The invention aims to solve the technical problem of how to enable a non-RedCAP terminal to acquire the most abundant bandwidth resources.
In order to solve the technical problems, the invention provides an optimization method for selecting a 5G access cell by a non-RedCAP terminal, which comprises the following steps. Step S1: and the non-RedCAP terminal receives the SIB1 message issued by the 5G NR cell, judges whether the 5G NR cell supports access of the RedCAP terminal, and acquires the system bandwidth capability of the network of the 5G NR cell and the bandwidth part BWP configured for the non-RedCAP terminal from the SIB1 message. Step S2: the non-RedCAP terminal stores information whether the 5G NR cell supports access of the RedCAP terminal and the system bandwidth capability of the network of the 5G NR cell each time the non-RedCAP terminal resides in the 5G NR cell; and after each time the non-RedCAP terminal successfully switches cells or receives neighbor information of network configuration conditional switching, the neighbor relation of a new 5G NR cell is stored. Step S3: the non-RedCAP terminal judges whether a currently accessed 5G NR cell supports the access of the RedCAP terminal; if yes, go to step S4; if not, go back to step S2. Step S4: the non-RedCAP terminal judges whether a cell optimization triggering condition is met; if yes, the non-RedCAP terminal stores the information of the currently accessed 5G NR cell, and then step S5 is carried out; if not, step S4 is repeated at intervals. Step S5: the non-RedCAP terminal judges whether a currently accessed 5G NR cell has a neighbor cell with larger system bandwidth or not and whether the neighbor cell which does not support the access of the RedCAP terminal or not; if not, returning to the step S2; if yes, actively measuring the signal intensity of the adjacent 5G NR cell, reporting a measurement report to a base station, and switching or reselecting the non-RedCAP terminal to a neighboring cell corresponding to the measurement report by the base station; or the non-RedCAP terminal is directly switched to the adjacent cell of the active measurement signal intensity through conditional switching.
Further, in the step S1, after receiving the SIB1 message issued by the 5G NR cell, the non-RedCap terminal finds that any one or more of the following two conditions exist, that is, (1) the SIB1 message does not include the intra freqReselection RedCap; (2) The value of the interFreqReselectionRedCAP in the SIB1 message is notAllowed; the 5G NR cell is considered not to support the access of the RedCap terminal; otherwise, the 5G NR cell is considered to support the access of the RedCAP terminal.
Further, in the step S2, the non-RedCap terminal can determine whether the currently accessed 5G NR cell has a neighboring cell with a larger system bandwidth and whether the currently accessed neighboring cell does not support the access of the RedCap terminal according to the previously stored neighboring cell relationship.
Further, in the step S4, the cell optimization triggering condition refers to any one of the following two: the service scene of the current application of the non-RedCAP terminal has higher requirement on the rate, and the current network speed of the non-RedCAP terminal is limited.
Preferably, if the non-RedCap terminal is running an app of a preset kind, or is running an app in a preset list, or the network rate is greater than or equal to a first threshold value in 10 consecutive seconds, it indicates that the traffic scenario currently applied by the non-RedCap terminal has a higher rate requirement. The first threshold is, for example, between 1Mbps and 5 Mbps.
Preferably, if the modem of the non-RedCap terminal receives that the number of RBs allocated by the network is less than or equal to the second threshold, it indicates that the current network speed of the non-RedCap terminal is limited. The second threshold is for example between 30 and 50.
Further, in the step S5, if the judgment of yes is arbitrary, a plurality of neighboring cells are obtained, and a target cell is determined from the neighboring cells according to the priority order; the priority of the adjacent cell which does not support the access of the RedCAP terminal is higher than that of the adjacent cell which supports the access of the RedCAP terminal; if a plurality of adjacent cells which do not support access of the RedCAP terminal exist, taking the order from large to small of the system bandwidth as a priority order; if a plurality of adjacent cells supporting access of the RedCAP terminal exist, the order of the system bandwidth from large to small is also used as a priority order; according to the stored neighbor cell information, the non-RedCAP terminal actively measures the signal intensity of the target cell, if the signal intensity of the target cell is greater than or equal to a third threshold value, the non-RedCAP terminal reports the measurement result without considering the signal intensity of the current cell, and a base station switches or reselects the non-RedCAP terminal to the target cell; or, the non-RedCap terminal is directly switched to the target cell through conditional switching. The signal strength is greater than or equal to a third threshold, for example SS-RSRP ∈equal to-105 dBm.
The application also provides an optimization device for selecting the 5G access cell by the non-RedCAP terminal, which comprises a message analysis unit, an information storage unit, a first judgment unit, a second judgment unit and a third judgment unit. The message parsing unit is configured to receive an SIB1 message issued by a 5G NR cell, determine whether the 5G NR cell supports access of a RedCap terminal, and obtain a system bandwidth capability of a network of the 5G NR cell and a bandwidth portion BWP configured by the 5G NR cell for the non-RedCap terminal from the SIB1 message. The information storage unit is used for storing information whether the 5G NR cell supports access of the RedCAP terminal and the system bandwidth capability of the network of the 5G NR cell when the non-RedCAP terminal resides in the 5G NR cell each time; and the method is also used for storing the neighbor relation of the new 5G NR cell after the non-RedCAP terminal successfully switches cells each time or receives neighbor information of the conditional switch of network configuration. The first judging unit is used for judging whether the currently accessed 5G NR cell supports access of the RedCAP terminal; if yes, the processing is continued by the second judging unit; if not, the return information holding unit continues the processing. The second judging unit is used for judging whether the cell optimization triggering condition is met or not; if yes, the information of the 5G NR cell accessed currently is saved, and then the information is delivered to a third judging unit for continuous processing; if not, the operation is repeated at intervals. The third judging unit is used for judging whether the currently accessed 5G NR cell has a neighboring cell with larger system bandwidth or not and whether the currently accessed 5G NR cell does not support the access of the remote access terminal or not; if all the information is not processed, the return information storage unit continues processing; if yes, the non-RedCAP terminal actively measures the signal intensity of the adjacent 5G NR cell, reports a measurement report to the base station, and the base station switches or reselects the non-RedCAP terminal to the adjacent cell corresponding to the measurement report; alternatively, the non-RedCap terminal is directly handed over to the neighbor cell actively measuring the signal strength by conditional handoff.
The invention has the technical effects that: and enabling the non-RedCAP terminal to access to the 5G NR cell which does not support the RedCAP terminal preferentially, so as to strive for obtaining more bandwidth resources for the non-RedCAP terminal. The 5G network is characterized by a large bandwidth, high rate. The cost of the 5G terminal is reduced by the RedCAP, the capacity of the 5G cell is affected by the access of a large number of RedCAP terminals, and the resources of non-RedCAP users in the cell are reduced. According to the invention, the non-RedCAP terminal can intelligently switch to the 5G cell which does not support the access of the RedCAP terminal or the 5G cell with larger capacity when the non-RedCAP terminal has a high-speed service scene by learning the 5G cell configuration message issued by the network, so that the more sufficient resources of the 5G cell where the non-RedCAP terminal is located are ensured, and the use experience of a user is improved.

Description of the embodiments
Referring to fig. 1, the optimization method for selecting a 5G access cell by a non-RedCap terminal according to the present application includes the following steps.
Step S1: the non-RedCAP terminal receives SIB1 information issued by a 5G NR cell, judges whether the 5G NR cell supports access of the RedCAP terminal, and acquires the system Bandwidth capability of the network of the 5G NR cell and BWP (Bandwidth Part) configured by the 5G NR cell for the non-RedCAP terminal from the SIB1 information. The non-RedCap terminal refers to a mobile terminal not belonging to the RedCap terminal. The SIB1 message defines scheduling of other SIBs and contains information required for a UE (user equipment, i.e., mobile terminal) to access a cell. Wherein the SIB represents a system information block (System Information Block). The system bandwidth capability of the network represents the total carrier bandwidth of the cell (carrier bandwidth), known by the carrier bandwidth in the SIB1 message. BWP is a subset or part of the total carrier bandwidth of the cell, which implements bandwidth adaptation by configuring the UE with one or more BWP and telling the UE which BWP to activate.
After receiving the SIB1 message issued by the 5G NR cell, the non-RedCAP terminal finds that any one or more of the following two conditions exist (1) the SIB1 message does not contain the intra FreqReselection RedCAP; (2) The value of the interFreqReselectionRedCAP in the SIB1 message is notAllowed; the 5G NR cell is not considered to support the RedCap terminal access. Otherwise, the 5G NR cell is considered to support the access of the RedCAP terminal.
Step S2: the non-RedCAP terminal stores information of whether the 5G NR cell supports access of the RedCAP terminal and the system bandwidth capability of the network of the 5G NR cell each time the non-RedCAP terminal resides in the 5G NR cell. The non-RedCap terminal stores the neighbor relation of the new 5G NR cell each time it successfully switches cells or receives neighbor information of conditional switch (Conditional Hand Over, CHO) of network configuration. Through the neighbor relation stored before, the non-RedCAP terminal can judge whether the currently accessed 5G NR cell has a neighbor cell with larger system bandwidth or not and whether the currently accessed 5G NR cell does not support the access of the RedCAP terminal or not.
Step S3: and the non-RedCAP terminal judges whether the currently accessed 5G NR cell supports the access of the RedCAP terminal. If so, step S4 is entered. If not, go back to step S2.
Step S4: and the non-RedCAP terminal judges whether the cell optimization triggering condition is met. The cell optimization triggering condition refers to any one of the following two items: the service scene of the current application of the non-RedCAP terminal has higher requirement on the rate, and the current network speed of the non-RedCAP terminal is limited. The above two judging conditions are only met, and the condition that the cell optimization triggering condition is met is indicated, at this time, the non-RedCap terminal stores the information of the currently accessed 5G NR cell, and then step S5 is performed. If the two judging conditions are not met, the condition that the cell optimization triggering condition is not met is indicated, and the step S4 is repeated at intervals.
As an example, if the non-RedCap terminal is running a preset kind of app, such as a game app (especially an athletic-type game app), a video app, a live app, etc.; or running apps within a preset list; or the network rate of the non-RedCap terminal is greater than or equal to a first threshold value in 10 continuous seconds, the fact that the non-RedCap terminal has a large data interaction requirement is indicated, namely the current service scene of the non-RedCap terminal has higher rate requirement. The first threshold is, for example, between 1Mbps and 5 Mbps.
As an example, if the modem (modem) of the non-RedCap terminal receives the number of RBs (resource blocks) allocated by the network is less than or equal to the second threshold, it indicates that the rate of the non-RedCap terminal is limited, and a more abundant resource is needed for the 5G NR serving cell. The second threshold is for example between 30 and 50.
Step S5: and the non-RedCAP terminal judges whether the currently accessed 5G NR cell has a neighbor cell with larger system bandwidth or not and whether the currently accessed neighbor cell does not support the access of the RedCAP terminal. If both the above two judging conditions are negative, the process returns to step S2. If only one of the above two judging conditions is yes, the signal strength of the adjacent 5G NR cell (serving as a target cell) is actively measured. And if yes, determining a target cell from the adjacent cells according to the priority order. The priority of the neighbor cell which does not support access of the RedCap terminal is higher than the priority of the neighbor cell which supports access of the RedCap terminal. If a plurality of adjacent cells which do not support access of the RedCAP terminal exist, the order of the system bandwidth from large to small is used as the priority order. If a plurality of adjacent cells supporting access of the RedCAP terminal exist, the order of the system bandwidth from large to small is also used as the priority order. The priority of the neighbor cell which has the smallest system bandwidth and does not support the access of the RedCAP terminal is also higher than the priority of the neighbor cell which has the largest system bandwidth and does not support the access of the RedCAP terminal. After actively measuring the signal intensity of the target cell, if the signal intensity of the target cell is greater than or equal to a third threshold value, the non-RedCAP terminal reports a measurement report to the base station, and the base station switches or reselects the non-RedCAP terminal to the target cell without considering the signal intensity of the current cell. Or, the non-RedCAP terminal is directly switched to the target cell through conditional switching. The signal strength is greater than or equal to a third threshold, for example, SS-RSRP (Synchronization Signal Reference Signal Received Power, synchronous signal reference signal received power) is greater than or equal to-105 dBm. After actively measuring the signal intensity of a target cell, if the signal intensity of the target cell is smaller than a third threshold value, selecting a neighbor cell with the next priority as the target cell; if there is no neighbor cell of the next priority, the whole flow ends.
The 5G cells supporting the RedCap terminals allow the RedCap terminals to access, and thus the number of mobile terminals to which they access tends to be significantly larger than the number of mobile terminals to which the 5G cells not supporting the RedCap terminals access. The bandwidth allocated to each mobile terminal by the 5G cell supporting the RedCap terminal is often smaller than the bandwidth allocated to each mobile terminal by the 5G cell not supporting the RedCap terminal. The non-RedCAP terminal triggers a process of searching for a better 5G cell, namely, the process is to avoid staying in the 5G cell supporting the RedCAP terminal as much as possible so as to avoid resource limitation; and 5G cells with abundant resources are accessed as much as possible and service is carried out.
Referring to fig. 2, the optimizing apparatus for selecting a 5G access cell by a non-RedCap terminal according to the present application includes a message parsing unit 1, an information saving unit 2, a first judging unit 3, a second judging unit 4, and a third judging unit 5. The apparatus shown in fig. 2 corresponds to the method shown in fig. 1.
The message parsing unit 1 is configured to receive SIB1 message sent by a 5G NR cell, determine whether the 5G NR cell supports access of a RedCap terminal, and obtain, from the SIB1 message, a system bandwidth capability of a network of the 5G NR cell, and a BWP configured by the 5G NR cell for the non-RedCap terminal.
The information storage unit 2 is configured to store, when a non-RedCap terminal resides in a 5G NR cell each time, information whether the 5G NR cell supports access of the RedCap terminal and a system bandwidth capability of a network of the 5G NR cell; and the method is also used for storing the neighbor relation of the new 5G NR cell after the non-RedCAP terminal successfully switches cells each time or receives neighbor information of the conditional switch of network configuration.
The first judging unit 3 is configured to judge whether a currently accessed 5G NR cell supports access of a RedCap terminal. If so, the processing is continued by the second judging unit 4. If not, the return information holding unit 2 continues the processing.
The second judging unit 4 is configured to judge whether a cell optimization triggering condition is satisfied. The cell optimization triggering condition refers to any one of the following two items: the service scene of the current application of the non-RedCAP terminal has higher requirement on the rate, and the current network speed of the non-RedCAP terminal is limited. The above two judging conditions are satisfied only if one is satisfied, which means that the cell optimization triggering condition is satisfied, and the second judging unit 4 saves the information of the currently accessed 5G NR cell, and then gives the information to the third judging unit 5 for further processing. If both of the above two judgment conditions are not satisfied, it means that the cell optimization trigger condition is not satisfied, and the second judgment unit 4 repeats operations at intervals.
The third judging unit 5 is configured to judge whether the currently accessed 5G NR cell has a neighboring cell with a larger system bandwidth, and whether the currently accessed 5G NR cell has a neighboring cell that does not support access of the RedCap terminal. If all of the above two judgment conditions are negative, the return information holding unit 2 continues the processing. If one of the two judging conditions is yes, taking the neighbor cell meeting the condition as a target cell, actively measuring the signal intensity of the target cell by a non-RedCAP terminal, reporting a measurement report to a base station, and switching or reselecting the non-RedCAP terminal to the target cell by the base station. Alternatively, the non-RedCap terminal is handed over directly to the target cell by conditional handoff.
The optimization method for selecting the 5G access cell by the non-RedCAP terminal is to preferentially strive for accessing the 5G NR cell which does not support the RedCAP terminal for the non-RedCAP terminal. The number of mobile terminals of the 5G NR cells which do not support access of the RedCAP terminal is smaller, so that more bandwidth resources can be allocated for the non-RedCAP terminal.
The above are only preferred embodiments of the present invention, and are not intended to limit the present invention. Various modifications and variations of the present invention will be apparent to those skilled in the art.
