Referring to fig. 1, a flow diagram of one embodiment of a user equipment operating method according to the present disclosure is shown. The user equipment operation method is applied to user equipment such as a smart phone with mobile communication capability. As shown in fig. 1, the user equipment operation method includes the following steps:

step 101, when an NSA/AA dual-mode user equipment is attached to an LTE cell, detecting a message signaling issued by the LTE cell.

The UE is an important part of a mobile communication system, and may include a mobile phone, an intelligent terminal, a multimedia device, a streaming media device, and so on. In this embodiment, the NSA/AA dual-mode user equipment may be an intelligent terminal such as a5G mobile phone that supports both an NSA networking mode and an SA networking mode. The NSA is a non-independent networking mode, namely a networking mode with a 4G network and a5G network coexisting, the 5G network can be used when the network is good, and the 4G network can be switched to when the network is poor, the networking mode is flexible, and the application range is wide in the initial stage of 5G construction. The SA is an independent 5G networking mode, and is directly connected to a5G network, and is not switched to 4G at will, which is relatively high in cost. LTE (Long Term Evolution) is a Long Term Evolution of The umts (Universal Mobile Telecommunications System) technical standard established by The 3GPP (The 3rd Generation Partnership Project) organization. In LTE, a base station may be configured to suspend multiple cells, where each cell is an LTE cell. In an LTE system, UE (user equipment) identifies cells by using a cell search process, and resides in and performs an attachment process after selecting a proper cell. The LTE cell can page surrounding user equipment by issuing a message signaling, and the message signaling issued by the cell takes effect on all the user equipment accessed to the cell. When the ue is attached to the LTE cell, the ue may detect a message signaling sent by the LTE cell.

And 102, determining whether the neighbor cell of the LTE cell has a5G cell in an SA networking mode or not based on the message signaling.

Based on the message signaling detected in step 101, the user equipment may analyze the content of the message signaling to determine whether the neighboring cell of the LTE cell has a5G cell in an SA networking mode according to an analysis result. The neighboring cell of the LTE cell is another cell to which the user equipment may be handed over from the current LTE cell.

Step 103, setting the SA function of the user equipment to a corresponding on or off state according to whether the neighboring cell of the LTE cell has a5G cell in an SA networking mode.

In this embodiment, when a neighboring cell of the LTE cell has a5G cell in an SA networking mode, the user equipment may be set to an on state. On the contrary, when the neighboring cell of the LTE cell does not have a5G cell in an SA networking mode, the SA function of the user equipment may be set to a closed state. For example, when the neighboring cells of the LTE cell are all NSA networking, the SA function of the user equipment may be set to an off state.

In some optional implementations of this embodiment, step 102 may specifically include: and when the user equipment is in an idle state, determining whether the neighbor cell of the LTE cell has a5G cell in an SA networking mode according to whether the message signaling contains SIB24 broadcast messages. Generally, when the user equipment detects the SIB24 broadcast message from the message signaling, it may be determined that the neighboring cell of the LTE cell has a5G cell in an SA networking manner. And if the user equipment does not detect the SIB24 broadcast message, waiting for the user equipment to enter a connected state. The message signaling may include various system messages at a cell level, and the system information may be divided into MIB messages and various SIB messages, where each system information includes a series of parameter sets related to a certain function. The SIB24 broadcast message is one of SIB messages specifically introduced in the 4G cell to implement the reselection operation from 4G to 5G, and when a5G SA system exists in the neighboring cell of the LTE cell, it broadcasts the SIB24 to all the user terminals of the cell. And judging whether the neighbor cell of the LTE cell has a5G cell in an SA networking mode or not according to whether the detected message signaling contains SIB24 broadcast messages or not.

In some optional implementations of this embodiment, step 102 may include: and when the user equipment is in a connection state, determining whether the neighbor cell of the LTE cell has a5G cell in an SA networking mode according to whether the message signaling contains NR neighbor cell measurement and control information. When planning an NR neighboring cell (i.e., a5G neighboring cell), the LTE cell performs measurement and control on the NR neighboring cell, and issues the obtained measurement and control information of the NR neighboring cell when issuing a message signaling. Therefore, the user equipment can analyze whether the message signaling contains the measurement and control information of the NR neighbor cell, and can determine whether the neighbor cell of the LTE cell has the 5G cell in the SA networking mode according to the analysis result.

In some optional implementation manners of this embodiment, the determining whether the neighboring cell of the LTE cell has the 5G cell in the SA networking manner according to whether the message signaling includes the NR neighboring cell measurement and control information may include: and if the message signaling does not contain the measurement and control information of the NR neighbor cell, determining that the neighbor cell of the LTE cell does not have a5G cell in an SA networking mode.

In some optional implementation manners of this embodiment, the determining, according to whether the NR neighboring cell measurement and control information is included in the message signaling, whether a5G cell in an SA networking manner exists in a neighboring cell of the LTE cell includes: if the message signaling contains NR neighboring cell measurement and control information, analyzing SSB frequency point information of each frequency point in the NR neighboring cell measurement and control information; determining whether at least one SSB frequency point indicating an SA5G cell exists in each SSB frequency point information; when at least one SSB frequency point indicating an SA5G cell exists, determining that the SA5G cell exists in a neighboring cell of the LTE cell; and when the SSB frequency point indicating the SA5G cell does not exist, determining that the SA5G cell does not exist in the adjacent cell of the LTE cell. In this implementation manner, when the message signaling sent by the LTE cell includes the NR neighbor measurement and control information, the next processing may be performed. Firstly, analyzing the SSB frequency point information of each frequency point in the NR neighboring cell measurement and control information. The SSB, i.e., the Synchronization Signal and PBCH block, is composed of three parts, namely Primary Synchronization Signals (PSS), secondary Synchronization Signals (SSS), and PBCH. The SSB frequency points are usually set independently for the 5G system due to flexibility requirements. When an LTE cell performs NR neighbor measurement, measurement and control are usually performed based on SSB frequency points, and the obtained NR neighbor measurement and control information includes information of each SSB frequency point. And the user equipment analyzes the SSB frequency point information of each frequency point, so that whether the SSB frequency point indicates the SA5G cell can be determined. And when at least one SSB frequency point indicating the SA5G cell exists, determining that the SA5G cell exists in the adjacent cell of the LTE cell. Otherwise, when the SSB frequency point indicating the SA5G cell does not exist, determining that the SA5G cell does not exist in the adjacent cell of the LTE cell.

In some optional implementation manners of this embodiment, whether at least one SSB frequency point that conforms to the GSCN exists in each SSB frequency point information is detected; and if the SSB frequency point conforming to the GSCN does not exist, determining that the SSB frequency point indicating the SA5G cell does not exist. The GSCN is a global synchronization channel number, which is a unique number for each frequency domain location. Specifically, whether the 5G neighboring cell of the current 4G cell is in an NSA networking mode can be judged by judging whether the SSB frequency point information carrier freq-r15 in the measurement and control information measObjectNR matches with the GSCN, that is, if the effective GSCN cannot be calculated through the SSB frequency point number, the neighboring cell corresponding to the corresponding frequency point is in an NSA networking mode. If the effective GSCN can be calculated, the neighboring cell corresponding to the corresponding frequency point may be in an SA networking mode, and may be further processed. The mode of calculation of GSCN is shown in the following table:

for example, SSB frequency bin number 504990, 2524.95Mhz equals 2524950khz for GSCN =3 × n + (M-3)/2 =3 × 2104+ (3-3)/2 =6312.

In some optional implementation manners of this embodiment, the determining whether there is at least one SSB frequency point indicating an SA5G cell in each SSB frequency point information further includes: if SSB frequency points which accord with the GSCN exist, searching SSB blocks corresponding to the SSB frequency points aiming at the SSB frequency points which accord with the GSCN, analyzing MIB system information and calculating KSSB fields; determining whether an SSB frequency point corresponding to the KSSB field in a preset value range exists; and if not, determining that at least one SSB frequency point indicating the SA5G cell does not exist. The KSSB indicates a frequency domain interval, which is a frequency domain interval from subcarrier 0 of the SSB to subcarrier 0 of Common RB overlapping with the SSB. The KSSB has two roles, the first role is to calculate the CORSET0 or the starting point of the carrier bandwidth frequency domain, and the second role is to deduce whether the current SSB configures the related SIB1 according to the value of the KSsb. The KSSB field may include 4 bits, and the 4 bits have 16 values, wherein a partially taken value may be used to indicate an offset between Resource Elements (REs) between the control Resource set and the SSB, and the like. When the SSB frequency point indicates an SA5G cell, the KSSB field is usually within a certain value range. Therefore, whether the frequency point is likely to be the SSB frequency point of the SA5G cell can be determined by the SSB frequency point corresponding to the KSSB field within the preset value range. If not, determining that the SSB frequency point indicating the SA5G cell does not exist. If present, subsequent operations may be performed. Specifically, the above range may be 0 < = KSSB < =23. According to the 3GPP TS 38.211 protocol, if KSSB > 23, the SSB synchronous block is only used for measurement, and does not bear a control resource set Corset0 of a scheduling SIB1, but not a Cell Defined SSB synchronous block representing a Defined Cell of a5G adjacent Cell, namely, a corresponding measurement frequency point cannot be an SA networking mode. On the contrary, if 0 < = KSSB < =23, the corresponding measurement frequency point may be in the SA networking mode.

In some optional implementation manners of this embodiment, determining whether there is at least one SSB frequency point indicating an SA5G cell in each SSB frequency point information further includes: if the SSB frequency points corresponding to the KSSB fields in the preset value range exist, analyzing the identifier of the scheduling S1B1 on a control resource set Corset0 bearing the scheduling S1B1 at each SSB frequency point aiming at the SSB frequency points corresponding to the KSSB fields in the preset value range; if at least one SSB frequency point of which the analyzed identifier contains a tracking area identification code cell exists, determining that at least one SSB frequency point indicating an SA5G cell does not exist; and if the SSB frequency point of which the analyzed identifier contains the tracking area identification code cell does not exist, determining that at least one SSB frequency point indicating the SA5G cell exists. The system information at cell level is validated for all user equipment accessing the cell. SIB1 is one of the SIDs that contains scheduling information and access related information for other cells. coreset (countrol REsource SET) is introduced in NR for the definition of the SET of localized physical resources for PDCCH channel, there may be multiple coresets for one cell PDCCH channel, and each coreset has an ID number. Wherein coreset 0 is the set of physical resources corresponding to Type 0 Common Search space (RMAI). The CORESET 0 is configured by the MIB, the continuous RB number occupied by the CORESET 0 in the frequency domain, the continuous symbol number occupied in the time domain, the multiplexing type and the offset of the CORESET 0 and the SSB can be known through a high-4-bit index table look-up, and the monitoring time of the corresponding PDCCH can be known through a low-4-bit index table look-up. The Tracking Area Identity (TAI) is used to identify a Tracking Area and is composed of MCC, MNC and Tracking Area Code (TAC). Generally, if the determination result KSSB is within the preset value range in the foregoing steps, the additional steps in this implementation manner may be performed. That is, the DCI of scheduling SIB1 is parsed on the control resource set Corset0 carrying the scheduling SIB1, thereby parsing out the identifier of SIB1. And judging whether each identifier analyzed by each SSB frequency point contains a tracking area identification code cell or not. According to a 3GPP TS 38.331 protocol, if there is no SSB frequency point of which the analyzed identifier contains a tracking area identification code cell, it can be determined that there is no SSB frequency point of at least one indication SA5G cell in the adjacent area of the LTE cell. On the contrary, if the user equipment judges that at least one SSB frequency point of which the analyzed identifier contains the tracking area identification code cell exists, the user equipment can determine that at least one SSB frequency point of the indication SA5G cell exists in the adjacent cell of the LTE cell.

In this embodiment, a signaling message sent to the user equipment by the LTE network side can be fully utilized, and the user equipment can autonomously and intelligently identify whether a5G network in an SA networking mode exists under the coverage of the current area, so that the automatic SA opening or SA closing function is realized, and the power consumption problem caused by the invalid SA network search of an NSA/SA dual-mode 5G mobile phone is solved. In addition, the method of the embodiment does not need the participation of a cloud platform server deployed by an operator, and compared with the function of accurately opening and closing the terminal SA according to the geographic region based on the current operator cloud platform scheme containing the national SA network geographic position information, the method based on the 3GPP can be suitable for medium and small brand mobile phone manufacturers without operator cooperation channels besides 5G customized machine types deeply cooperating with head operators, and is higher in universality.

Continuing to refer to fig. 2a, a flow diagram of yet another embodiment of a method of operation of a user equipment according to the present disclosure is shown. The user equipment operation method is applied to the mobile terminal. The method for operating the user equipment as shown in fig. 2a includes the following steps:

step 201, when an NSA/AA dual-mode user equipment is attached to an LTE cell, detecting a message signaling issued by the LTE cell.

In this embodiment, the NSA/AA dual mode user equipment may default to the SA function in the off state when the user equipment is powered on. When the NSA/AA dual-mode terminal is attached to the LTE cell, the message signaling sent by the attached LTE cell can be detected.

Step 202, determine whether the ue is in an idle state.

In this embodiment, the ue may determine whether the state of the ue is idle or connected, so as to perform the following according to the determination result.

Step 203, when the ue is in the idle state, detecting whether the message signaling contains the SIB24 broadcast message.

In this embodiment, when the ue is in an idle state when attached to the LTE network, it may be further detected whether the message signaling includes an SIB24 broadcast message.

Step 204, if the message signaling includes SIB24 broadcast message, it is determined that the neighboring cell of the LTE cell has a5G cell in SA networking mode.

Generally, whether a5G neighboring cell of a current 4G cell is in a mode including SA networking is preliminarily known through whether an LTE network issues an SIB24 broadcast message. In this embodiment, when the user equipment detects the SIB24 broadcast message from the message signaling, it may be determined that the neighboring cell of the LTE cell has the 5G cell in the SA networking mode.

Step 205, if the message signaling does not include the SIB24 broadcast message, wait for the ue to enter a connection state.

In this embodiment, when the message signaling does not include the SIB24 broadcast message, it cannot be confirmed that the 5G cell in the SA networking mode exists in the neighboring cell of the LTE cell. At this time, it is necessary to wait for the ue to enter a connection state. When the user equipment enters the connected state, the following step 206 may be performed.

Step 206, when the user equipment is in the connection state, detecting whether the message signaling contains the NR neighbor measurement and control information.

In this embodiment, when it is determined that the ue is in the connected state, it may be further detected whether the message signaling includes NR neighbor measurement and control information, and the detection result may be used to perform subsequent steps.

Step 207, if the message signaling does not contain the NR neighbor cell measurement and control information, it is determined that the neighbor cell of the LTE cell does not have a5G cell in an SA networking mode.

In this embodiment, when the detection result in step 206 is that the message signaling does not include NR neighbor measurement and control information, it may be directly determined that the neighbor cell of the LTE cell does not have a5G cell in an SA networking mode.

And step 208, if the message signaling contains the NR neighboring cell measurement and control information, analyzing the SSB frequency point information of each frequency point in the NR neighboring cell measurement and control information.

In this embodiment, when it is detected that the message signaling includes NR neighbor measurement and control information in step 206, SSB frequency point information of each frequency point may be further analyzed from the NR neighbor measurement and control information.

Step 209, determine whether there is at least one SSB frequency point indicating the SA5G cell in each SSB frequency point information.

In this embodiment, after analyzing each SSB frequency point information based on step 208, the user equipment may determine whether at least one SSB frequency point indicating an SA5G cell exists in each SSB frequency point information.

Step 210, when at least one SSB frequency point indicating the SA5G cell exists, determining that the SA5G cell exists in a neighboring cell of the LTE cell.

In this embodiment, when it is identified through step 209 that at least one SSB frequency point indicating an AA 5G cell exists, it may be determined that an SA5G cell exists in a neighboring cell of the LTE cell.

And step 211, determining that the SA5G cell does not exist in the neighboring cell of the LTE cell when the SSB frequency point indicating the SA5G cell does not exist.

In this embodiment, when it is identified through step 209 that at least one SSB frequency point indicating an SA5G cell does not exist, it may be determined that the SA5G cell does not exist in the neighboring cell of the LTE cell.

Step 212, according to whether the neighboring cell of the LTE cell has a5G cell in an SA networking mode, setting the SA function of the user equipment to a corresponding on or off state.

In this embodiment, when it is obtained through the foregoing step 204, step 207, step 210, or step 211 that whether the neighboring cell of the LTE cell has the 5G cell in the SA networking mode, the SA function of the user equipment may be set to a corresponding on or off state. That is, when the 5G cell in the SA networking mode exists, the SA function is turned on, otherwise, the SA function is set to the off state.

In some optional implementation manners of this embodiment, the determining in step 209 whether there is at least one SSB frequency point indicating an SA5G cell in each SSB frequency point information may be performed in a manner shown in fig. 2b, and specifically includes the following steps:

step 2091, detecting whether at least one SSB frequency point conforming to GSCN exists in each SSB frequency point information.

In this step, the mode of detecting whether the SSB frequency point conforms to the GSCN may be that the effective GSCN cannot be calculated through the SSB frequency point number. The information of each SSB frequency point can be detected in sequence, so that whether at least one SSB frequency point which accords with the GSCN exists is judged.

Step 2092, if there is no SSB frequency point conforming to GSCN, it is determined that there is no SSB frequency point indicating the SA5G cell.

In this step, if an effective GSCN cannot be calculated through the SSB frequency point number, the neighboring cell corresponding to the corresponding frequency point is the NSA networking.

Step 2093, if the SSB frequency points conforming to the GSCN exist, searching the SSB blocks corresponding to the SSB frequency points aiming at the SSB frequency points conforming to the GSCN, analyzing the MIB system message and calculating the KSSB field.

And under the condition that SSB frequency points conforming to the GSCN exist, further processing the screened SSB frequency points conforming to the GSCN. First, SSB blocks corresponding to SSB bins, i.e., SSB blocks in the 5G domain, are searched. Secondly, the MIB system message is analyzed from the searched SSB block. The SSB block system information can be divided into MIB (masterinformation block) and various SIBs (analysis information block), and each system information includes a series of parameter sets related to a certain function. The most important system information is carried in PBCH, which is called MIB. Next, the KSSB field can be calculated through the MIB system message. In general, the KSSB field may be represented by 5 bits, the MIB indicates 4 bits, and the remaining 1bit is in the PBCH payload.

Step 2094, determine whether there is an SSB frequency point corresponding to the KSSB field within the preset value range.

Specifically, the value range may be 0 < = KSSB < =23. According to the 3GPP TS 38.211 protocol, if KSSB > 23 indicates that the SSB block is only used for measurement, and does not carry the control resource set Corset0 of the scheduling SIB1, but not the Cell Defined SSB block of the Defined Cell representing the 5G neighboring Cell, i.e. the corresponding SSB frequency point cannot be in an SA networking mode. On the contrary, if 0 < = KSSB < =23, the corresponding measurement frequency point may be in the SA networking mode.

Step 2095, if not, determining that the SSB frequency point indicating the SA5G cell does not exist.

Based on the previous step, when the KSSB calculated by each SSB frequency point is not within the value range, it indicates that each SSB frequency point is not an indication SA5G cell, that is, it can be determined that there is no SSB frequency point indicating an SA5G cell.

Step 2096, if there is an SSB frequency point corresponding to the KSSB field within the preset value range, then, for the SSB frequency point corresponding to the KSSB field within the preset value range, the identifier of the scheduling S1B1 is analyzed on the control resource set Corset0 bearing the scheduling S1B1 at each SSB frequency point. SIB1 is one of the SIBs that contains scheduling information and access related information of other cells. coreset (countrol REsource SET) is introduced in NR for the definition of the SET of localized physical resources for PDCCH channel, there may be multiple coresets for one cell PDCCH channel, and each coreset has an ID number. Wherein coreset 0 is the set of physical resources corresponding to Type 0 Common Search space (RMAI). CORESET 0 is configured by MIB, the continuous RB number occupied by CORESET 0 in the frequency domain, the continuous symbol number occupied in the time domain, the multiplexing type and offset of CORESET 0 and SSB can be known through table look-up of high 4-bit index, and the monitoring time of the corresponding PDCCH can be known through table look-up of low 4-bit index.

Based on step 2904, if there are SAB frequency points whose corresponding KSSB fields are within the preset value range, it is indicated that the SSB frequency points whose corresponding KSSB fields are within the preset value range may indicate the SA5G cell, so that further processing can be performed. That is, the identifier of the scheduling S1B1 is analyzed on the control resource set Corset0 carrying the scheduling S1B1 at each SSB frequency point.

Step 2097, identify whether there is an SSB frequency bin with the parsed identifier containing the tracking area identifier cell.

This step can identify whether the identifier obtained in the foregoing process contains the tracking area identification code cell, and further identify whether there is an SSB frequency point where the analyzed identifier contains the tracking area identification code cell. A Tracking Area Identity (TAI) is used to identify a Tracking Area, and is composed of MCC, MNC and Tracking Area Code (TAC).

Step 2098, if not, determining that at least one SSB frequency point indicating the SA5G cell does not exist.

In this step, when there is no SSB frequency bin in which the analyzed identifier contains the tracking area identifier cell, it can be said that any SSB frequency bin is not the SSB frequency bin indicating the SA5G cell.

Step 2099, if yes, determines that at least one SSB frequency point indicating the SA5G cell exists.

In this step, when a certain analyzed identifier contains a tracking area identifier cell, it can indicate that the SSB frequency point indicates an SA5G cell, that is, it can determine that there is at least one SSB frequency point indicating the SA5G cell.

In this embodiment and its optional implementation manner, the user equipment fully utilizes the SSB frequency point number in the measurement and control information of the surrounding 5G neighbor Cell sent by the LTE Cell and the broadcasted system message SIB24 to perform signaling Cell level calculation and prejudgment, and can autonomously identify whether the surrounding 5G neighbor Cell exists, thereby turning on or off the terminal SA function, further improving the SA neighbor Cell identification accuracy according to the KSSB value range, and excluding the Cell Defined SSB synchronization block of the Defined Cell of the non-5G neighbor Cell.
