[0038] The paging method provided by the embodiments of the present application will be described in detail below with reference to the accompanying drawings through specific embodiments and their application scenarios.
[0039] As Figure 2 shown, the embodiments of the present application provide a paging method, including:
[0040] Step 201: The network-side device determines a first resource according to the terminal information and the paging indication information, where the paging indication information is used to indicate the time-domain configuration information of the paging message, and there is an association relationship between the time-domain configuration information of the paging message and the beam scanning information.
[0041] Here, the above terminal information may include at least one of a terminal identifier, a terminal wave position identifier, and position change information of the terminal.
[0042] The above beam scanning information may include at least one of the following:
[0043] Beam scanning period;
[0044] Number of wave positions within the satellite coverage area;
[0045] Number of wave position dwell times within the beam scanning period, where the wave position dwell time refers to the dwell time at each wave position;
[0046] Number of sets of wave positions within the satellite coverage area;
[0047] Number of wave positions within each set of wave positions;
[0048] Area size of each wave position;
[0049] Wave position identifier, which is determined according to the beam scanning order and is used to identify the wave position;
[0050] Spatial position information corresponding to each wave position identifier;
[0051] Beam scanning mode.
[0052] In the embodiments of the present application, the satellite scans within the satellite coverage area according to a certain scanning order, such as row-by-row scanning, through beam scanning, and determines the wave position identifier of each wave position according to the scanning order, where the area on the ground corresponding to the beam is the wave position.
[0053] Optionally, the paging indication information includes at least one of the following:
[0054] Number I of system frames included in the paging period T f ;
[0055] Number I of beam scanning periods T included in the paging period T s ; s ;
[0056] Number I of wave position dwell times T included in the beam scanning period T s ; b ; b ;
[0057] Number I of sets of paging opportunities POC included in the paging period T poc ;
[0058] Number I of paging opportunities PO included in the set of paging opportunities POC po ;
[0059] The number I of detection opportunities MO included in the paging opportunity PO pm ;
[0060] The dwell time T of the waveform position b The number I of detection opportunities MO included therein m ;
[0061] The beam scanning period T s The number of paging opportunity sets POC included therein;
[0062] The beam scanning period T s The number of paging opportunities PO included therein.
[0063] It should be noted that in the embodiments of the present application, the paging period is in units of frames, the lengths of each POC within the paging period are the same, and the length of each POC is an integer multiple of system frames. Among them, (SFN1 + offset1) mod T = 0, SFN1 represents the starting system frame number of the paging period, offset1 represents the offset configured by the system, and T can include 32, 64, 128, or 256 system frames. Of course, this is only an example here, and the paging period can also include other numbers of system frames.
[0064] Step 202: The network-side device transmits a paging message on the first resource, and the paging message is used to page at least one terminal located within the satellite coverage area.
[0065] Optionally, the determined first resource includes at least one PO, and each PO corresponds to at least one MO.
[0066] This step 202 includes: sending the same paging message among all the MOs corresponding to the PO.
[0067] In the paging method of the embodiments of the present application, an association relationship is established between the time-domain configuration information of the paging message and the beam scanning information, and based on the time-domain configuration information of the paging message associated with the beam scanning information, the first resource for transmitting the paging message is determined. Furthermore, the paging message can be sent to the terminal within the satellite coverage area through this first resource, realizing paging based on beam scanning.
[0068] As a first optional implementation manner, the paging indication information includes:
[0069] The beam scanning period T s The number of paging opportunities PO included therein is one.
[0070] Based on this, the terminal information includes a terminal identifier; then
[0071] Determining the first resource according to the terminal information and the paging indication information includes:
[0072] Determine the N1-th PO in the M1-th POC as the first resource;
[0073] where M1 = UE_ID mod I poc ; N1 = floor(UE_ID div I poc ) mod I po ;
[0074] UE_ID represents the terminal identifier.
[0075] Specifically, the implementation method will be described from four parts: satellite beam scanning setting, Paging physical layer time domain setting, system paging setting, and terminal blind detection.
[0076] 1) Satellite beam scanning setting.
[0077] There are I b wave positions in the satellite coverage area. The satellite scans the coverage area in a certain way, such as row-by-row scanning, and completes the scanning within the beam scanning period T s . There are I s wave position dwell times T b in one beam scanning period T b .
[0078] 2) Paging physical layer time domain setting.
[0079] One paging period T contains I poc POCs;
[0080] One POC contains I po POs;
[0081] One beam scanning period T s contains one PO, and this PO corresponds to all wave positions in the satellite coverage area;
[0082] The wave position dwell time T b contains I m logically consecutive MOs, where I m is greater than or equal to 1. If there are multiple MOs at the same wave position, multiple detection opportunities can be provided for the terminal.
[0083] 3) System paging setting.
[0084] Before the network side device initiates paging to the satellite coverage area, paging indication information has been configured on the terminal side, including the paging period, the number of POCs I poc , the number of POs I po , the number of wave position dwell times in one PO I b , the number of MOs in one wave position dwell time Im Given the paged terminal ID (UE_ID), the above paging indication information and beam scanning mapping relationship are as follows Figure 3 shown. Figure 3 The paging message (PM) in the middle contains the paging messages of several terminals. The maximum number of terminals that can be paged in each paging message is at most maxNrofPageRec. In the relevant protocol, maxNrofPageRec = 32. In this application, the maximum number of terminals that can be paged is not specifically limited.
[0085] The network side device transmits the paging messages of a group of terminals in the N1th PO in the M1th POC. Specifically, the paging messages sent in all the MOs corresponding to this PO are the same. The descriptions of M1 and N1 refer to the above formula and will not be elaborated here.
[0086] 4) Terminal blind detection.
[0087] Terminals in the radio resource control idle state and the radio resource control inactive state receive paging messages in a discontinuous reception manner, that is, the terminal only listens to the time of one PO in each paging cycle. The terminal knows the paging indication message before listening, such as the paging cycle, the number of POCs I poc , the number of POs I po , the number of wave position dwell times in one PO I b , the number of MOs in one wave position dwell time I m , and then determines the listening time slot by using the terminal identifier. Specifically, the terminal continuously listens to K1 MOs starting from the R1th MO of the first system frame number until it receives its own paging message. Among them, (SFN2 + offset2) mod T = (T div I poc ) * (UE_ID mod I poc );
[0088] R1 = S * I b * I m ; S = floor(UE_ID div I poc ) mod I po ; K1 = I b * I m , UE_ID represents the terminal identifier, I b represents the number of wave positions in the satellite coverage area, SFN2 represents the first system frame number, offset2 represents the offset configured by the system, and the first system frame number is the starting system frame number of the POC where the terminal is located.
[0089] In this implementation, since the network side equipment does not obtain or use the specific location information of the terminal for paging, it is necessary to send paging messages to each beam position in accordance with the scanning order through beam scanning, and complete the paging of a group of terminals in the satellite coverage area after one beam scanning cycle.
[0090] As a second optional implementation, the beam scanning period T s Contains a POC;
[0091] The wave position residence time T b Contains a PO;
[0092] The number of POs in the POC is the same as the number of wave positions in the satellite coverage area.
[0093] The terminal information includes the terminal identifier and the terminal's wave position identifier;
[0094] Based on this, determining the first resource according to the terminal information and the paging indication information includes:
[0095] Determine the N2th PO in the M2th POC as the first resource;
[0096] Where M2 = UE_IDmodI poc ; N2 = b_ID;
[0097] UE_ID represents the terminal identifier, and b_ID represents the waveband identifier of the terminal.
[0098] Specifically, the implementation method is described below from four parts: satellite beam scanning setting, paging physical layer time domain setting, system paging setting, and terminal blind detection.
[0099] 1) Satellite beam scanning settings.
[0100] Satellite coverage area exists I b The satellite scans the beam in a certain way, such as line by line, during the beam scanning period T s The scanning of the coverage area is completed within 10 seconds, and each beam position ID is determined according to the scanning sequence. A beam scanning cycle T s There is I b Wave position residence time T b .
[0101] 2) Paging physical layer time domain settings.
[0102] A paging cycle T contains I poc POCs;
[0103] A POC contains I po POs;
[0104] A beam scanning period T s contains a POC, and the number of POs in the POC is the same as the number of wave positions in the satellite coverage area, that is, the POs and the wave positions are in one-to-one correspondence;
[0105] A wave position dwell time T b contains I m logically consecutive MOs, where I m is greater than or equal to 1. If there are multiple MOs in the same wave position, multiple detection opportunities can be provided for the terminal.
[0106] 3) System paging settings.
[0107] Before the network-side device initiates paging to the satellite coverage area, paging indication information has been configured on the terminal side, including the paging cycle, the number of POCs I poc , the number of POs I po , the number of MOs in a PO I m , and the ID of the terminal to be paged (UE_ID) is known. The above paging indication information and the beam scanning mapping relationship are as Figure 4 shown. Figure 4 The paging message (Paging Message, PM) in it contains the paging messages of several terminals, and the maximum number of terminals that can be paged in each paging message is at most maxNrofPageRec. In the relevant protocol, maxNrofPageRec = 32. In this application, the maximum number of terminals that can be paged is not specifically limited.
[0108] The network-side device transmits the paging messages of a group of terminals in the N2th PO in the M2th POC. Specifically, the paging messages sent in all MOs corresponding to this PO are the same. The explanations of M2 and N2 refer to the above formula and will not be elaborated here.
[0109] 4) Terminal blind detection.
[0110] Terminals in the Radio Resource Control idle state and the Radio Resource Control inactive state receive paging messages in a discontinuous reception manner, that is, the terminal only listens to the time of one PO in each paging cycle. The terminal knows the paging indication message before listening, such as the paging cycle, the number of POCs I poc , the number of POs I po , the number of MOs in a PO I m , and then determines the listening time slot by using the terminal identifier and the wave position identifier. Specifically, the terminal continuously listens to I m MOs starting from the R2th MO of the first system frame number until it receives its own paging message. Among them, (SFN2 + offset2) mod T = (T div I poc ) * (UE_ID mod Ipoc ); R2 = b_ID * I m ; UE_ID represents the terminal identifier, b_ID represents the wave position ID of the terminal, SFN2 represents the first system frame number, offset2 represents the offset configured by the system, and the first system frame number is the starting system frame number of the POC where the terminal is located.
[0111] This implementation method performs paging by means of the position of the terminal. The satellite only needs to send a paging message to the wave position where the terminal is located to complete the paging, which can greatly improve the paging capacity.
[0112] As a third optional implementation method, the beam scanning period T s contains one POC;
[0113] The wave position dwell time T b contains one PO;
[0114] Wherein, the number of POs in the POC is the same as the number of wave positions in the satellite coverage area.
[0115] The terminal information includes the position change information and the terminal identifier of the terminal; then
[0116] Based on this, determining the first resource according to the terminal information and the paging indication information includes:
[0117] Determining the paging message distribution parameter according to the position change information of the terminal;
[0118] Determining the set of wave position identifiers corresponding to the paging message according to the paging message distribution parameter;
[0119] Determining the first resource according to the set of wave position identifiers, the terminal identifier, and the paging indication information.
[0120] Further optionally, determining the set of wave position identifiers corresponding to the paging message according to the paging message distribution parameter includes:
[0121] Determining the first wave position set according to the paging message distribution parameter, wherein the wave positions in the first wave position set are at a distance less than the distance indicated by the paging message distribution parameter from the terminal wave position;
[0122] Determining the set of wave position identifiers corresponding to the paging message according to the identifier of the terminal wave position and the identifiers of the wave positions in the first wave position set.
[0123] In the embodiments of the present application, the paging message distribution parameter is determined according to the terminal location change information, such as being determined according to the degree of terminal location change, and the degree of location change is determined by factors such as the wave position size, the time since the last location update, and the moving speeds of the satellite and the terminal. Exemplarily, the above paging message distribution parameter indicates that the wave position IDs of s wave positions within k circles adjacent to the terminal wave position are recorded in ascending order as a1, a2, a3,..., as, then the above wave position identification set is A, and A = {a1, a2, a3,... as}. Optionally, k is used to indicate the number of circles of wave positions adjacent to the terminal wave position, such as Figure 5 as shown, k = 1 indicates that the wave position IDs of s wave positions within 1 circle adjacent to the terminal wave position constitute the above wave position identification set, and k = 2 indicates that the wave position IDs of s wave positions within 2 circles adjacent to the terminal wave position constitute the above wave position identification set.
[0124] Further optionally, determining the first resource according to the wave position identification set, the terminal identification, and the paging indication information includes:
[0125] Determining the N3th PO in the M3th POC as the first resource;
[0126] wherein, M3 = UE_ID mod I poc ; N3 includes each element in the wave position identification set A;
[0127] UE_ID represents the terminal identification, A = {a1, a2,..., as}, and the total number of wave position identifications in the wave position identification set is s.
[0128] Specifically, the implementation manner will be described below from four parts: satellite beam scanning setting, paging physical layer time domain setting, system paging setting, and terminal blind detection.
[0129] 1) Satellite beam scanning setting.
[0130] There are I b wave positions in the satellite coverage area. The satellite scans the coverage area in a certain manner, such as row-by-row scanning, and completes the scanning of the coverage area within the beam scanning period T s , and determines the wave position ID of each one according to the scanning order. There are I s wave position residence times T b in one beam scanning period T b , and records the wave position ID and its corresponding spatial position. Among them, the wave position ID and its corresponding spatial position are called wave position planning information. Exemplarily, the above spatial position information may be longitude and latitude information, etc.
[0131] 2) Paging physical layer time domain setting.
[0132] There are I poc POCs in one paging period T;
[0133] One POC contains I po POs;
[0134] One beam scanning period T s contains one POC, and the number of POs in the POC is the same as the number of wave positions in the satellite coverage area;
[0135] One wave position dwell time T b contains I m logically consecutive MOs, where I m is greater than or equal to 1. If there are multiple MOs at the same wave position, multiple detection opportunities can be provided for the terminal.
[0136] 3) System paging settings.
[0137] Before the network-side device initiates paging to the satellite coverage area, wave position planning information and paging indication information have been configured on the terminal side, including the paging cycle, the number of POCs I poc , the number of POs I po , the number of MOs in one POC I m and the paging message distribution parameter k, and the ID of the paged terminal (UE_ID) and the wave position ID are known. The above paging indication information and the beam scanning mapping relationship are as Figure 6 shown. Figure 6 The paging message (Paging Message, PM) in it contains the paging messages of several terminals, and the maximum number of terminals that can be paged in each paging message is at most maxNrofPageRec. In the relevant protocol, maxNrofPageRec = 32. In this application, the maximum number of terminals that can be paged is not specifically limited.
[0138] The network-side device transmits a group of terminal paging messages in the N3rd PO in the M3rd POC. Specifically, the paging messages sent in all MOs corresponding to this PO are the same. The descriptions of M3 and N3 refer to the above formula and will not be elaborated here.
[0139] 4) Terminal blind detection.
[0140] Terminals in the Radio Resource Control idle state and the Radio Resource Control inactive state receive paging messages in a discontinuous reception manner. The terminal knows the paging indication message and the wave position planning information, such as the paging cycle T, the number of POCs I poc , the number of POs I po , the number of MOs in one POC I mAnd the paging message distribution parameter k, and then determine the listening time slot by using the terminal identifier and the wave position identifier. Specifically, the terminal listens to the a-th PO starting from the first system frame number until it receives its own paging message. Wherein, a includes each element in the wave position identifier set A, and (SFN2 + offset2) mod T = (T div I poc ) * (UE_ID mod I poc ); A = {a1, a2,..., as}, the total number of wave position identifiers in the wave position identifier set is s, UE_ID represents the terminal identifier, SFN2 represents the first system frame number, the first system frame number is the starting system frame number of the POC where the terminal is located, and offset2 represents the offset configured by the system.
[0141] In this implementation manner, the terminal listens to the a1, a2, a3,..., as-th PO starting from the starting system frame number of the POC where it is located, that is, in this implementation manner, the terminal listens to multiple POs according to its own position change information.
[0142] In the above-mentioned third optional implementation manner, the paging message is designed centered on the terminal, that is, the paging message of each terminal will be distributed in the paging messages of this wave position and adjacent wave positions, which can improve the paging capacity and robustness at the same time.
[0143] In addition, in the embodiments of the present application, the network device may also send the first indication information. When the first indication information is the first identifier (such as true), the terminal determines the first resource by using the second optional implementation manner based on the above-mentioned paging indication information, that is, the terminal listens to a single PO. When the first indication information is the second identifier (such as false), the terminal determines the first resource by using the above-mentioned third optional implementation manner based on the above-mentioned paging indication information, that is, the terminal listens to multiple POs.
[0144] Of course, in the embodiments of the present application, the terminal may also first use the second optional implementation manner to listen to the PO based on the above-mentioned paging indication information, and when the paging message is not listened to based on the second optional time slot manner, further adopt the above-mentioned third optional implementation manner to listen to the paging message.
[0145] As a fourth optional implementation manner, the number of POCs included in the beam scanning period T s is one, and the number of POs I po included in the POC is equal to the number I bc of the wave position set, and the number of wave positions in the wave position set corresponding to each PO is in turn
[0146] The terminal information includes the terminal identifier and the wave position identifier of the terminal; then
[0147] Determining the first resource according to the terminal information and the paging indication information includes:
[0148] Determining the N4th PO in the M4th POC as the first resource;
[0149] where M4 = UE_ID mod I poc ;
[0150] UE_ID represents the terminal identifier, b_ID represents the wave position identifier of the terminal, and I cb,k represents the number of wave positions in the wave position set k.
[0151] Specifically, the implementation is described below from four parts: satellite beam scanning setting, paging physical layer time domain setting, system paging setting, and terminal blind detection.
[0152] 1) Satellite beam scanning setting.
[0153] In the satellite coverage area, a clustered wave position set is divided. There are I bc wave position sets in the satellite coverage area, and the number of wave positions in each wave position set is successively The paging messages sent in the same wave position set are the same. The satellite completes the beam scanning inside each wave position set in a certain way, such as row-by-row scanning, sets the scanning order of the wave position set, and completes the scanning of the coverage area within the scanning period T s according to the scanning order of the wave position set, and determines each wave position ID according to the scanning order. There are I b wave position residence times T b in the scanning time of a wave position set. In the embodiments of the present application, the wave position set includes at least two adjacent wave positions. As Figure 7 shown, 7 wave positions with wave position identifiers from 0 to 6 form a wave position set. As Figure 8 shown, 3 wave positions with wave position identifiers from 0 to 2 form a wave position set, and 3 wave positions with wave position identifiers from 3 to 5 form a wave position set.
[0154] 2) Paging physical layer time domain setting.
[0155] One paging period T contains I poc POCs;
[0156] One POC contains I po POs;
[0157] One beam scanning period T s contains one POC, and the number of POs in the POC is the same as the number of wave position sets in the satellite coverage area, that is, I po = I bc ;
[0158] A wave position dwell time T b including I m logically consecutive MOs, where I m is greater than or equal to 1. If there are multiple MOs in the same wave position, multiple detection opportunities can be provided for the terminal.
[0159] 3) System paging settings.
[0160] Before the network-side device initiates paging to the satellite coverage area, paging indication information has been configured on the terminal side, including the paging cycle, the number I of POCs poc , the number I of POs po , and the number of wave positions in the wave position set corresponding to each of the POs is successively the number I of MOs within a wave position dwell time m , and the ID of the terminal (UE_ID) to be paged and its wave position ID are known. The above paging indication information and the beam scanning mapping relationship are as Figure 9 shown. Figure 9 The paging message (Paging Message, PM) in the middle contains the paging messages of several terminals. The maximum number of terminals that can be paged in each paging message is at most maxNrofPageRec. In the relevant protocol, maxNrofPageRec = 32. In this application, the maximum number of terminals that can be paged is not specifically limited.
[0161] The network-side device transmits the paging messages of a group of terminals in the N4th PO in the M4th POC. Specifically, the paging messages of the terminals located within the wave position set corresponding to a certain wave position set are transmitted in the PO corresponding to that wave position set. The descriptions of M4 and N4 refer to the above formula and will not be elaborated here.
[0162] 4) Terminal blind detection.
[0163] Terminals in the Radio Resource Control idle state and the Radio Resource Control inactive state receive paging messages in a discontinuous reception manner. That is, the terminal only listens to the time of one PO in each paging cycle. The terminal knows the paging indication information before listening, such as the paging cycle T, the number I of POCs poc , the number I of POs po , and the number of wave positions in the wave position set corresponding to each of the POs is successively the number I of MOs within a wave position dwell time m , and then determines the listening time slot by using the terminal identifier and the wave position identifier. Specifically, the terminal continuously listens to I starting from the R3rd MO of the first system frame number cb,Q *I ma MO until it receives its own paging message. Wherein, (SFN2 + offset2) mod T = (T div I poc ) * (UE_ID mod I poc ); Wherein, UE_ID represents the terminal identifier, b_ID represents the wave position identifier of the terminal, SFN2 represents the first system frame number, offset2 represents the offset configured by the system, and the first system frame number is the starting system frame number of the POC where the terminal is located.
[0164] In this implementation method, a clustered wave position set design is carried out. The paging messages sent under the same wave position set are the same. By repeatedly sending the paging message through multiple wave positions, the paging robustness is improved.
[0165] In the paging method of the embodiment of the present application, an association relationship is established between the time domain configuration information of the paging message and the beam scanning information, and based on the time domain configuration information of the paging message associated with the beam scanning information, the first resource for transmitting the paging message is determined.
