[0116] The present disclosure will be described in further detail below with reference to the accompanying drawings and embodiments.

[0117] In the related art, the network side can broadcast the slice information supported by each frequency through the system information block (SIB) 16 in the system message, or send the slice information for cell reselection (also understood as slice-based cell reselection information) to the terminal through dedicated RRC signaling (such as RRC release (which can be expressed as RRCRelease in English) message, etc.). The slice information may include the identifier of the NSAG (such as ID, etc.), the TAC of the NSAG, the cell reselection priority for the NSAG (that is, the cell reselection priority based on the NSAG, which can also be understood as the cell reselection priority based on the slice), the cell list that supports NSAG (that is, the allowed cell list, which can be expressed as allowed cell list in English), and the cell list that does not support NSAG (that is, the excluded cell list, which can be expressed as excluded cell list in English), etc. Exemplarily, the slice information broadcast through SIB16 can be as shown in Table 1, assuming that the smaller the value of the cell reselection priority, the higher the cell reselection priority; frequency F1 supports NSAG#1 and NSAG#2, the cell reselection priority value based on NSAG#1 is 6, the cell reselection priority value based on NSAG#2 is 5, only cell #1 and cell#2 support NSAG#1, and all cells except cell#4 support NSAG#2. The traditional (which can be expressed as Legacy in English) cell reselection priority value of F1 is 3; F2 supports NSAG#1, the cell reselection priority value based on NSAG#1 is 4, and the traditional cell reselection priority value is 5. Because there is no broadcast allowed cell list and excluded cell list, it can be considered that all cells of this frequency support NSAG#1; F3 supports NSAG#2, the cell reselection priority value based on NSAG#2 is 4, there is no traditional cell reselection priority, and all cells of this frequency support NSAG#2; F4 does not support any NSAG, and the traditional cell reselection priority value is 4.

[0118] Table 1

[0119] In addition, the network side can also provide the terminal with the priority of the NSAG supported by the terminal through the Non-Access Stratum (NAS). The terminal can derive the cell reselection priority based on NSAG for multiple frequencies according to the priority of the NSAG supported by itself, the slice information broadcast by SIB16 and / or the slice information in the dedicated RRC signaling, and the rules defined by the relevant technology to obtain a new frequency priority list; thereafter, the terminal can reselect and evaluate the frequencies according to the derived frequency priority list. Among them, the overall principle of deriving the frequency priority list may include: the cell reselection priority of the frequency supporting high-priority NSAG is higher than the cell reselection priority of the frequency supporting low-priority NSAG; the cell reselection priority of the frequency supporting any NSAG is higher than the cell reselection priority of the frequency not supporting any NSAG; for frequencies supporting the same or same-priority NSAG, the frequency priority can be determined according to the cell reselection priority based on NSAG.

[0120] For example, assuming the NSAG priority provided by the NAS to the terminal is NSAG#1 taking precedence over NSAG#2, the actual representation may be a specific priority value or priority order (ascending or descending), for example, NSAG#1 (priority value 3) and NSAG#2 (priority value 4). Assuming that the lower the priority value, the higher the priority. For the high-priority NSAG#1, both frequencies F1 and F2 are supported, with cell reselection priorities of 6 and 4, respectively. Assuming that the lower the cell reselection priority value, the higher the cell reselection priority, then F2 has a higher priority than F1 (simply expressed as F2 > F1). For the second-priority NSAG#2, both F1 and F3 are supported. Since F1 is already considered when sorting frequencies based on NSAG#1, only F3 is considered, and the new priority order is F2 > F1 > F3. For the frequency that does not support any NSAG, that is, F4, it has the lowest priority, so the terminal derives the frequency priority order as F2 > F1 > F3 > F4.

[0121] The terminal reselects and evaluates the frequencies in the derived frequency priority list. If the highest ranked cell (which can be expressed as highest ranked cell in English) or the best cell (which can be expressed as best cell in English) of the highest priority frequency meets the cell reselection criteria of different frequencies, the same frequency, or the same priority different frequencies, but does not support the NSAG corresponding to the frequency when the terminal derives the cell reselection priority based on NSAG, the terminal needs to consider the NSAG supported by the cell (instead of the NSAG of the corresponding frequency) and re-derive the cell reselection priority of the frequency; if the cell does not support other NSAGs (that is, other NSAGs except the NSAG corresponding to the frequency when the terminal derives the cell reselection priority based on NSAG, that is, the cell does not support any NSAG), the terminal can derive according to the traditional cell reselection priority, that is, re-sort the cell reselection priority of the frequencies. Exemplarily, for the frequency priority F2>F1>F3>F4 derived by the terminal in the above example, the terminal can first evaluate the cells on F2. Assuming that cell#3 is the best cell, but cell#3 does not support NSAG#1 (that is, when the terminal derives the cell reselection priority based on NSAG, the NSAG corresponding to frequency F2 is NSAG#1), then the terminal needs to re-derive the cell reselection priority of F2 based on other NSAGs supported by cell#3 except NSAG#1; assuming that cell#3 does not support other NSAGs, the above frequencies (that is, F1, F2, F3, F4) can be re-sorted according to the traditional cell reselection priority of F2. Since the traditional cell reselection priority of F2 (priority value is 5) is lower than the traditional cell reselection priority of F4 (priority value is 4), the terminal's updated frequency priority is F1>F3>F4>F2; thereafter, the terminal can continue to evaluate F1, that is, measure the cells on F1, until a suitable cell is reselected.

[0122] From the above description, it can be seen that in the related art, for the frequency priority list derived by the terminal based on NSAG, if the highest-ranked cell or the best cell of the highest priority frequency does not support the NSAG corresponding to the frequency when the terminal derives the cell reselection priority based on NSAG, then the terminal needs to re-derive the cell reselection priority based on NSAG and then re-reselect the cell, which not only prolongs the cell reselection time of the terminal, but also increases the power consumption of the terminal. In addition, from the perspective of the network side, on the one hand, it indicates that there may be coverage holes in the slice; on the other hand, it indicates that the slice information broadcast by SIB16 and / or the slice information in the dedicated RRC signaling may not better support the terminal to perform slice-based cell reselection.

[0123] Based on this, in various embodiments of the present disclosure, the terminal reports the NSAG-based cell reselection related information to the network side, so that the network side can subsequently use the NSAG-based cell reselection related information to perform corresponding network optimization operations, such as performing slice coverage blind spots, updating the NSAG-based cell reselection priority in the system message and / or RRC signaling, updating the allowed cell list in the system message and / or RRC signaling, and updating the excluded cell list in the system message and / or RRC signaling, etc., etc., which can help the network side to achieve network optimization; and the network side can also help the terminal to perform slice-based cell reselection faster after network optimization, that is, it can increase the speed of the terminal to perform NSAG-based cell reselection, thereby reducing terminal power consumption and improving user experience.

[0124] Specifically, an embodiment of the present disclosure provides an information transmission method, applied to a terminal, including:

[0125] Sending first information to the network side, where the first information includes information related to cell reselection based on NSAG.

[0126] In actual application, the terminal may also be referred to as a terminal device or a user equipment (UE), or may also be referred to as a user.

[0127] In actual application, the sending of the first information to the network side can be understood as sending the first information to the network equipment deployed on the network side. The network equipment may specifically include a base station and / or a network management, etc. The network management may include operation management and maintenance (OAM), etc. The embodiment of the present disclosure does not limit the specific type of the network equipment, as long as it can realize its function (i.e., using the NSAG-based cell reselection related information to perform corresponding network optimization operations, such as performing slice coverage blind spots, updating the NSAG-based cell reselection priority in the system message and / or RRC signaling, updating the allowed cell list in the system message and / or RRC signaling, and updating the excluded cell list in the system message and / or RRC signaling, etc.).

[0128] In actual application, the first information may also be referred to as slice information or slice-based cell reselection information, etc. The embodiments of the present disclosure do not limit the specific name of the first information, as long as its function is implemented. In addition, it should be noted that in various embodiments of the present disclosure, "NSAG-based" can also be understood as "slice-based".

[0129] In actual application, the network side may send slice information for cell reselection to the terminal through a system message (i.e., SIB16) and / or RRC signaling (which may be referred to as the eleventh information in the subsequent description). The eleventh information may at least include the fifth information, and the fifth information represents the cell reselection priorities of the multiple frequencies based on NSAG indicated by the network side; and the network side may provide the priority of the NSAG supported by the terminal to the terminal through NAS, that is, the network side may send the fourth information to the terminal through NAS, and the fourth information represents the priority of one or more NSAGs supported by the terminal. After receiving the fourth and fifth information, the terminal may perform cell reselection based on NSAG based on the fourth and fifth information; in other words, the terminal may use the fourth and fifth information to derive the cell reselection priorities of the multiple frequencies based on NSAG, and perform cell reselection based on the derived cell reselection priorities of the multiple frequencies based on NSAG. When performing NSAG-based cell reselection, the terminal can record information such as the cell's support for slices, that is, record the NSAG-based cell reselection related information, that is, generate (which can be understood as determine) the first information, and send the first information to the network side.

[0130] Based on this, in one embodiment, the method may further include:

[0131] Using the fourth information and the fifth information, the cell reselection priorities of multiple frequencies based on NSAG are derived to obtain the third information, wherein the fourth information represents the priority of one or more NSAGs supported by the terminal, the fifth information represents the cell reselection priorities of the multiple frequencies based on NSAG indicated by the network side, and the third information represents the cell reselection priorities of the multiple frequencies based on NSAG derived by the terminal.

[0132] Here, the one or more NSAGs refer to at least one NSAG, the multiple NSAGs refer to at least two NSAGs; and the multiple frequencies refer to at least two frequencies.

[0133] In actual application, for the cell reselection priorities based on NSAG of multiple frequencies derived by the terminal, if the highest-ranked cell or the best cell (the highest-ranked cell or the best cell may be referred to as the first cell in the subsequent description) of the highest priority frequency (which may be referred to as the first frequency) meets the cell reselection criteria of different frequencies, the same frequency, or the same priority but different frequencies, but does not support the NSAG corresponding to the first frequency when the terminal derives the cell reselection priority based on NSAG, then the terminal needs to consider the NSAG supported by the first cell to re-derive the cell reselection priority of the first frequency; if the first cell does not support other NSAGs (that is, other NSAGs except the NSAG corresponding to the first frequency when the terminal derives the cell reselection priority based on NSAG, that is, the first cell does not support any NSAG), then the terminal can derive according to the traditional cell reselection priority of the first frequency, that is, re-sort the cell reselection priorities of the multiple frequencies.

[0134] Based on this, in one embodiment, the method may further include:

[0135] When the first condition is met, the fourth information, the fifth information, and the sixth information are used to re-derive the cell reselection priorities of multiple frequencies based on the NSAG to obtain updated third information; wherein,

[0136] The satisfying of the first condition indicates that the first cell satisfies the cell reselection criteria, but does not support the NSAG corresponding to the first frequency when the terminal derives the cell reselection priority based on NSAG; the first cell includes the highest-ranked cell or the best cell of the first frequency, and the first frequency includes the highest priority frequency derived by the terminal; the sixth information indicates the NSAG supported by the first cell or the cell reselection priority of the first frequency (that is, the traditional cell reselection priority of the first frequency).

[0137] Among them, in actual application, for the above-mentioned example scenario, it is assumed that the terminal receives the eleventh information shown in Table 1, and the terminal supports NSAG#1 (priority value is 3) and NSAG#2 (priority value is 4), and it is assumed that the smaller the value of the cell reselection priority, the higher the cell reselection priority; then the cell reselection priorities of multiple frequencies based on NSAG derived for the first time by the terminal are F2>F1>F3>F4. Next, assuming that cell #3 (i.e., the first cell) is the best cell for best frequency F2 (i.e., the first frequency), but cell #3 does not support NSAG #1 (i.e., the NSAG corresponding to the first frequency when the terminal derives the NSAG-based cell reselection priority), the terminal needs to re-derive the cell reselection priority for F2 based on other NSAGs supported by cell #3, except NSAG #1. Assuming that cell #3 does not support other NSAGs, the cell reselection priorities of frequencies F1, F2, F3, and F4 can be re-ordered according to the traditional cell reselection priority of F2. Since the traditional cell reselection priority of F2 (priority value 5) is lower than the traditional cell reselection priority of F4 (priority value 4), the terminal re-derives the cell reselection priorities for multiple frequencies based on NSAGs as F1 > F3 > F4 > F2. The terminal can then continue to measure cells on F1 until a suitable cell is reselected. As can be seen from the above description, the third information can include the cell reselection priority information for multiple frequencies based on NSAGs obtained by the terminal through at least one derivation (i.e., one or more derivations).

[0138] Based on this, in one embodiment, the third information may include at least one of the following:

[0139] one or more frequency lists, each frequency list comprising cell reselection priorities of the plurality of frequencies;

[0140] The terminal derives the NSAG corresponding to the cell reselection priority of the frequency.

[0141] Here, the one or more frequency lists refer to at least one frequency list, and the multiple frequency lists refer to at least two frequency lists. Furthermore, it is understood that the cell reselection priorities of the multiple frequencies included in a frequency list are derived by the terminal using the fourth information and the fifth information, or are derived by the terminal using the fourth information, the fifth information, and the sixth information. The cell reselection priorities of the multiple frequencies included in each frequency list may be the same or different.

[0142] It should be noted that the embodiments of the present disclosure do not limit the specific forms of expression of various priorities (ie, frequency cell reselection priority, NSAG cell reselection priority, NSAG priority), as long as their functions are achieved. Exemplarily, the various priorities may be expressed in the form of priority values, and the smaller the priority value, the higher the priority. For example, for NSAG#1 (priority value is 3) and NSAG#2 (priority value is 4), the priority of NSAG#1 is higher than that of NSAG#2; or, the various priorities may be expressed in the form of priority values, and the larger the priority value, the higher the priority. For example, for NSAG#1 (cell reselection priority value is 6) and NSAG#2 (cell reselection priority value is 5), the cell reselection priority of NSAG#1 is higher than that of NSAG#2; or, the priorities may be expressed in the order of arrangement, and the priorities arranged in front are higher. For example, the order of arrangement of F1, F3, F4, and F2 may be used to express the cell reselection priorities of F1>F3>F4>F2; or, the priorities may be expressed in the order of arrangement, and the priorities arranged in the back are higher. For example, the order of arrangement of F2, F4, F3, and F1 may be used to express the cell reselection priorities of F1>F3>F4>F2.

[0143] In actual application, although the first cell meets the cell reselection criteria (which may include cell reselection criteria for different frequencies, the same frequency, or the same priority different frequencies), since the first cell does not support the NSAG corresponding to the first frequency when the terminal derives the cell reselection priority based on NSAG, the terminal will not reside in the first cell. Assuming that the terminal resides in the second cell of the second frequency after multiple (i.e., at least two) derivations of cell reselection priorities, the NSAG-based cell reselection related information may specifically include (i.e., the first information may specifically include) at least one of the following:

[0144] an identifier of the first cell (such as an ID);

[0145] the first frequency;

[0146] a cell quality of the first cell;

[0147] one or more NSAGs supported by the first cell;

[0148] second information, where the second information indicates that the first cell does not support any NSAG;

[0149] one or more NSAGs supported by the first frequency;

[0150] TACs of one or more NSAGs supported by the first cell;

[0151] a cell reselection priority of one or more NSAGs supported by the first frequency;

[0152] The priority of one or more NSAGs supported by the terminal;

[0153] the third information;

[0154] the location of the terminal;

[0155] an identifier of the second cell (such as an ID);

[0156] the second frequency;

[0157] one or more NSAGs supported by the second frequency;

[0158] a cell reselection priority of one or more NSAGs supported by the second frequency;

[0159] a cell reselection priority of the second frequency;

[0160] a cell quality of the second cell;

[0161] one or more NSAGs supported by the second cell;

[0162] The TAC of one or more NSAGs supported by the second cell.

[0163] In actual application, it can be understood that since the terminal has undergone multiple (i.e., at least two) derivations of cell reselection priorities, each derivation and reselection evaluation can correspond to a first frequency and a first cell, the first information can include relevant information of at least one first cell (i.e., one or more first cells) and relevant information of at least one first frequency (i.e., one or more first frequencies).

[0164] In actual application, the terminal may implicitly indicate the frequency (i.e., the first frequency, the second frequency) in the first information, for example, by indicating the frequency through index information (index), 0 represents the service frequency, 1 corresponds to the first frequency in the inter-frequency neighbor list (which can be expressed as interFreqCarrierFreqList in English) of SIB4, and 2 corresponds to the second frequency in the list. Alternatively, the terminal may explicitly indicate the frequency (i.e., the first frequency, the second frequency) in the first information, for example, by using the Absolute Radio-Frequency Channel Number (ARFCN) frequency point to indicate the frequency, ARFCN-ValueNR represents the NR frequency, ARFCN-ValueEUTRA represents the Long Term Evolution (LTE) frequency, etc.

[0165] In actual application, when the first information includes the identifier of the first cell and the first frequency, for the above example scenario, the terminal may specifically record and report F2 and cell#3 to the network side.

[0166] In actual application, the specific expression of the cell quality (i.e., the cell quality of the first cell, the cell quality of the second cell) may include at least one of the information such as reference signal received power (RSRP), reference signal received quality (RSRQ), and signal to interference plus noise ratio (SINR). The embodiment of the present disclosure is not limited to this.

[0167] In actual application, when the first information includes one or more NSAGs supported by the first cell and the TAC of one or more NSAGs supported by the first cell, it means that the first information may include other NSAGs and TACs supported by the first cell except the NSAG corresponding to the first frequency when the terminal derives the cell reselection priority based on NSAG; if the first cell does not support other NSAGs except the NSAG corresponding to the first frequency when the terminal derives the cell reselection priority based on NSAG, that is, the first cell does not support any NSAG, then the first information may include the second information. For the above example scenario, the best cell cell#3 of the best frequency F2 does not support NSAG#1 or other NSAGs. In this case, the first information may include the second information. Assume that after the terminal derives the frequency priority of F1>F3>F4>F2, the best cell measured for F1 is cell#5, but cell#5 does not support NSAG#1 (because only cell#1 and cell#2 are in the allowed cell list, and only these two cells support NSAG#1), and cell#5 supports NSAG#2 (because only cell#4 is in the excluded cell list, and all other cells except cell#4 support NSAG#2). In this case, the terminal can record and report NSAG#2. If there is a TAC corresponding to NSAG#2, the terminal can report the TAC and NSAG#2 (that is, one or more NSAGs supported by the first cell) to the network side. If there is no TAC corresponding to NSAG#2, the TAC of the cell (Cell#5) can be reported by default.

[0168] In actual application, the embodiment of the present disclosure may not limit the specific form of expression of the second information. For example, the second information can be implemented through a specific empty field; or, a specific indication (expressed as indication in English) can be used to indicate that the first cell does not support other NSAGs except the NSAG corresponding to the first frequency when the terminal derives the cell reselection priority based on NSAG, that is, a specific indication is used to indicate that the first cell does not support any NSAG.

[0169] In actual application, when the first information contains the cell reselection priority of one or more NSAGs supported by the first frequency, for the above example scenario, the terminal can specifically record and report the cell reselection priority (priority value is 4) based on NSAG#1 of F2 (i.e. the first frequency) to the network side.

[0170] In actual application, considering that the network side may not save all configurations, the terminal can also report all cell reselection priority information configured in the system message (i.e. SIB16) and / or RRC signaling to the network side (i.e. the fifth information, such as all NSAG-based cell reselection priority information shown in Table 1); or, the terminal can also report all or part of the content of the eleventh information to the network side according to the pre-settings or instructions of the network side (such as all or part of the content shown in Table 1).

[0171] In actual application, it can be seen from the above description that the priority of one or more NSAGs supported by the terminal may include a specific priority value, or the priority of the NSAG may be reflected by the arrangement order of the NSAG (ascending or descending). For the above example scenario, the terminal may specifically record and report NSAG#1 (priority value is 3) and NSAG#2 (priority value is 4) to the network side; or, the terminal may report {NSAG#2, NSAG#1} in ascending order; or, the terminal may report {NSAG#1, NSAG#2} in descending order.

[0172] In actual application, the location of the terminal may include at least one of the following information: Global Positioning System (GPS) positioning information, Global Navigation Satellite System (GNSS) positioning information, cell identification (such as ID, etc.), etc., and the embodiments of the present disclosure are not limited to this.

[0173] In actual application, the terminal may determine what content the NSAG-based cell reselection related information needs to include through preset rules (such as protocol provisions, etc.), that is, the specific content included in the first information may be pre-set on the terminal. Alternatively, the network side may configure the terminal with what content the NSAG-based cell reselection related information needs to include.

[0174] Based on this, in one embodiment, the method may further include:

[0175] Receive tenth information sent by the network side, where the tenth information is used to indicate specific content included in the first information.

[0176] In actual application, the network side may request the terminal to report the first information.

[0177] Based on this, in one embodiment, the method may further include:

[0178] Receive seventh information sent by the network side, where the seventh information is used to request the first information.

[0179] Accordingly, in actual application, after receiving the seventh information, the terminal may send the first information to the network side. The terminal may report the first information to the network side via a random access report, or the terminal may report the first information via a newly defined message.

[0180] In actual application, the terminal may also actively report the first information to the network side.

[0181] In actual application, the terminal may first inform the network side that there is the first information to be reported; then, the network side may request the terminal to report the first information.

[0182] Based on this, in one embodiment, the method may further include:

[0183] Eighth information is sent to the network side, where the eighth information indicates that there is first information to be reported.

[0184] In actual application, a new specific field may be introduced into a specific message (such as a random access report, etc.) to implement the eighth information, that is, the field indicates to the network side that the terminal has the first information to be reported.

[0185] In actual application, the terminal may pre-set some trigger conditions or trigger events (hereinafter referred to as second conditions). When the second conditions are triggered, the terminal may send the first information to the network. Alternatively, the second conditions may be configured for the terminal by the network.

[0186] Based on this, in one embodiment, sending the first information to the network side may include:

[0187] When a second condition configured on the network side is met, the first information is sent to the network side; wherein the second condition may include one of the following:

[0188] Reporting time;

[0189] Reporting cycle;

[0190] The first cell exists;

[0191] There is first information to be reported.

[0192] In actual application, the terminal may also report to the network side whether it supports recording and / or reporting relevant information about cell reselection based on NSAG, that is, whether the terminal has the ability to record and / or report the first information. For example, the terminal may report to the network side through terminal capability information or other relevant auxiliary information that it supports reporting relevant information about cell reselection based on NSAG, or that it can record relevant information about cell reselection based on NSAG. In other words, the terminal may report to the network side through terminal capability information or other relevant auxiliary information that it has the ability to record and / or report the first information. For another example, when the terminal supports recording relevant information about cell reselection based on NSAG, the terminal may also report to the network side information indicating that it does not want to record the first information. The information may also carry the corresponding reason, such as high terminal power consumption, insufficient terminal power, limited terminal storage, etc. Alternatively, it may be assumed that all terminals that support slice-based cell reselection support recording relevant information about cell reselection based on NSAG.

[0193] Based on this, in one embodiment, the method may further include:

[0194] Ninth information is sent to the network side, where the ninth information indicates that the terminal has the ability to record and / or report the first information.

[0195] Accordingly, an embodiment of the present disclosure further provides an information transmission method, which is applied to a network device (such as a base station, a network management (such as OAM), etc.), including:

[0196] First information sent by a receiving terminal is received, where the first information includes information related to cell reselection based on NSAG.

[0197] In one embodiment, the method may further include:

[0198] Seventh information is sent to the terminal, where the seventh information is used to request the first information.

[0199] In one embodiment, the method may further include:

[0200] Eighth information sent by the terminal is received, where the eighth information indicates that there is first information to be reported.

[0201] In one embodiment, the method may further include:

[0202] Receive ninth information sent by the terminal, where the ninth information indicates that the terminal has the ability to record and / or report the first information.

[0203] In one embodiment, the method may further include:

[0204] Sending tenth information to the terminal, where the tenth information is used to indicate specific content included in the first information.

[0205] In actual application, after receiving the first information, the network device can use the NSAG-based cell reselection related information to perform corresponding network optimization operations, such as performing slice coverage blind spots, updating the NSAG-based cell reselection priority in the system message and / or RRC signaling, updating the allowed cell list in the system message and / or RRC signaling, and updating the excluded cell list in the system message and / or RRC signaling, etc., and at least one of the operations.

[0206] Based on this, in one embodiment, the method may further include:

[0207] Based on the first information, perform at least one of the following:

[0208] Perform section coverage and blind filling;

[0209] Update the NSAG-based cell reselection priority in system messages and / or RRC signaling;

[0210] Update the allowed cell list in system messages and / or RRC signaling;

[0211] Update the excluded cell list in system messages and / or RRC signaling.

[0212] In actual application, the system message may include SIB16, etc., and the RRC signaling may be understood as dedicated signaling of the terminal.

[0213] In actual application, if the highest-ranked cell or the best cell of the highest priority frequency does not support the corresponding NSAG, that is, the first cell does not support the NSAG corresponding to the first frequency when the terminal derives the cell reselection priority based on NSAG, then the network device can perform slice coverage blind spot filling, that is, deploy the corresponding slices; when performing slice coverage blind spot filling, the network device can consider the slices that need to be deployed together with information such as the terminal location.

[0214] In actual application, the updated system message and / or RRC signaling excluded cell list may include: when the SIB16 and / or dedicated RRC signaling does not originally contain the NSAG excluded cell list (which can be expressed as excluded cell list in English), the NSAG excluded cell list is added to the SIB16 and / or dedicated RRC signaling, and the list may include the highest ranking cell of the highest priority frequency (i.e., the first frequency) or the identifier of the best cell (i.e., the first cell) (such as ID, etc.); when the SIB16 and / or dedicated RRC signaling originally contains the NSAG excluded cell list, the highest ranking cell of the highest priority frequency (i.e., the first frequency) or the identifier of the best cell (i.e., the first cell) (such as ID, etc.) may be added to the list. In this way, when the terminal receives the updated system message and / or RRC signaling, it can know in advance that the first cell does not support the NSAG corresponding to the first frequency when the terminal derives the cell reselection priority based on NSAG. Then, when the terminal performs cell reselection based on NSAG, it does not need to evaluate the cell or read the system message of the cell to determine whether the corresponding NSAG is supported, thereby reducing terminal power consumption.

[0215] In actual application, the updated system message and / or the list of cells allowed in the RRC signaling may include: when the SIB16 and / or dedicated RRC signaling does not originally contain the NSAG allowed cell list (which can be expressed as allowed cell list in English), the NSAG allowed cell list is added to the SIB16 and / or dedicated RRC signaling, and the list may include the highest ranking cell of the highest priority frequency (i.e., the first frequency) or the identifier of the best cell (i.e., the first cell) (such as ID, etc.); when the SIB16 and / or dedicated RRC signaling originally contains the NSAG allowed cell list, the highest ranking cell of the highest priority frequency (i.e., the first frequency) or the identifier of the best cell (i.e., the first cell) (such as ID, etc.) may be added to the list.

[0216] In actual application, when the network device updates the allowed cell list and excluded cell list in the system message and / or RRC signaling based on the first information, it can also optimize the NSAG allowed cell list and excluded cell list in SIB16 and / or dedicated RRC signaling according to the identifier (such as ID, etc.) of the NSAG supported by the resident cell (i.e., the second cell).

[0217] In actual application, when the network device updates the NSAG-based cell reselection priority in SIB16 and / or dedicated RRC signaling based on the first information, the cell reselection priority can be lowered for the frequency where the terminal is not stationed (i.e., the first frequency); and the cell reselection priority can be increased for the frequency where the terminal is stationed (i.e., the second frequency). In addition, it can be understood that since SIB16 is a broadcast message, the network device can comprehensively consider the adjustment of the NSAG-based cell reselection priority in SIB16 based on the first information reported by a large number of terminals; and dedicated RRC signaling is a message for each terminal (which can be expressed as per UE in English), so the network device can adjust the NSAG-based cell reselection priority in the dedicated RRC signaling of a terminal based on the first information reported by the terminal.

[0218] In actual application, the network device can also update the NSAG-based cell reselection priority in SIB16 and / or dedicated RRC signaling based on the priority of one or more NSAGs supported by the terminal, that is, the network device can consider the priority of NSAGs reported by multiple terminals, such as configuring a higher cell reselection priority for NSAGs that support higher priorities, so that the terminal can reside in a cell that supports higher-priority NSAGs, reducing the delay and signaling consumption caused by subsequent switching.

[0219] Accordingly, an embodiment of the present disclosure further provides an information transmission method, as shown in FIG1 , the method comprising:

[0220] Step 101: The terminal sends first information to the network side, where the first information includes information related to cell reselection based on NSAG;

[0221] Step 102: The network side receives the first information sent by the terminal.

[0222] The information transmission method provided by the embodiment of the present disclosure is that the terminal sends first information to the network side, and the network side receives the first information sent by the terminal, and the first information includes information related to cell reselection based on NSAG. The solution provided by the embodiment of the present disclosure is that the terminal reports information related to cell reselection based on NSAG to the network side, so that the network side can subsequently use the information related to cell reselection based on NSAG to perform corresponding network optimization operations, such as performing slice coverage blind spots, updating the cell reselection priority based on NSAG in system messages and / or RRC signaling, updating the list of allowed cells in system messages and / or RRC signaling, and updating the list of excluded cells in system messages and / or RRC signaling, etc., which can help the network side to achieve network optimization; and the network side can also help the terminal to perform slice-based cell reselection faster after network optimization, that is, it can increase the speed of the terminal in performing NSAG-based cell reselection, thereby reducing terminal power consumption and improving user experience.

[0223] In order to implement the terminal-side method of the embodiment of the present disclosure, the embodiment of the present disclosure further provides an information transmission device, which is provided on the terminal. As shown in FIG2 , the device includes:

[0240] In order to implement the method on the network device side of the embodiment of the present disclosure, the embodiment of the present disclosure further provides an information transmission device, which is provided on the network device. As shown in FIG3 , the device includes:
