Description

Technical Field

[0001] The present application relates to the field of wireless communications, and in particular to an information transmission method, apparatus, related equipment, storage medium and computer program product. Background Art

[0002] In the related art, when a terminal is camping in a cell, the terminal can receive System Information Block 1 (SIB1) in the cell and listen to paging. The configuration used by the terminal to listen to paging is included in SIB1. The terminal can calculate its own paging occasion (PO) and paging frame (PF) based on the configuration, receive a paging message at the corresponding time, and check whether the paging message contains its own identification (such as ID, etc.). If it does, the terminal can access the network.

[0003] At the same time, the process of network paging a terminal may include: when the terminal context is released, the fifth generation mobile communication technology (5G) radio access network (NG-RAN, Next Generation Radio Access Network) node may provide the access and mobility management function (AMF, Access and Mobility Management Function) with a list of recommended units (i.e. recommended cells) and NG-RAN nodes as auxiliary information for subsequent paging. The AMF may provide paging attempt information such as the number of paging attempts (which can be expressed as paging attempt in English) and the expected number of paging attempts. The paging attempt information may also include the next paging area scope (which can be expressed as next paging area scope in English; it can also be called the next paging scope, which can be expressed as next paging scope in English). If the paging attempt information is included in the paging message, each paging NG-RAN node receives the same information (i.e. paging attempt information) during the paging attempt. And, the paging attempt count shall be increased by 1 for each new paging attempt. When the next paging scope appears, it can indicate whether the AMF plans to modify the currently selected paging area at the next paging attempt. If the terminal has changed the state to Connection Management (CM) CONNECTED, the paging attempt count will be reset.

[0004] However, in some specific scenarios, the terminal may miss the paging of the network. Summary of the invention

[0174] The present application is further described in detail below in conjunction with the accompanying drawings and embodiments.

[0175] One of the research objectives in the related art is to support on-demand SIB1 (which can be expressed as on-demand SIB1 in English), that is, the NES cell sends SIB1 only when there is a user equipment (UE, User Equipment; also known as a terminal) request (which can be expressed as request in English), thereby reducing downlink transmission and achieving energy saving; it should be noted that in the above process, the transmission of the synchronization signal block (SSB, Synchronization Signal / PBCH Block) is not affected. Based on the above process, for the NES cell, the UE can only reside if it obtains SIB1, which can specifically include three scenarios (i.e., scenario 1, scenario 2 and scenario 3 in the subsequent description). At the same time, in order to further study the on-demand SIB1 for idle / inactive mode UE, the radio access network 1 (RAN1, Radio Access Network 1) focuses on the following three scenarios (which can be expressed as For the further study of on-demand SIB1 for idle / inactive mode UE, RAN1 focuses its studies on the following cases):

[0176] Scenario 1, Option 1, Option A, and Option X (in English, it can be expressed as Case 1: Option 1+A+X);

[0177] Scenario 2, Option 1, Option B, and Option X (in English, it can be expressed as Case 2: Option 1+B+X);

[0178] Scenario 3, Option 2, Option B and Option Y (expressed in English as Case 3: Option 2+B+Y).

[0179] Among them, for the target cell of UL WUS transmission (expressed in English as On target cell of UL WUS transmission), Option 1 refers to the UE sending UL WUS to the NES cell (expressed in English as Option 1: UE transmits UL WUS to NES Cell), and Option 2 refers to the UE sending UL WUS to cell A (expressed in English as Option 2: UE transmits UL WUS to Cell A).

[0180] For the configuration provision for UL WUS transmission (expressed in English as On configuration provision for UL WUS transmission), Option A means that the UE obtains the UL WUS configuration from the NES cell (expressed in English as Option A: UE obtains the UL WUS configuration from NES Cell), and Option B means that the UE obtains the UL WUS configuration from cell A (expressed in English as Option B: UE obtains the UL WUS configuration from Cell A).

[0181] For the reception of SIB1 (expressed as On receiving of SIB1 in English), Option X means that the UE receives on-demand SIB1 from the NES cell (expressed as Option X: UE receives on-demand SIB1 from NESCell in English), and Option Y means that the UE receives on-demand SIB1 from cell A (expressed as Option Y: UE receives on-demand SIB1 from Cell A in English).

[0182] In addition, the UE's request for the on-demand SIB1 will be implemented based on the random access channel (RACH) of the random access (RA) process, and the on-demand SIB1 of the NES cell may be received after receiving the RAR.

[0183] However, for the above scenario 2, that is, in the scenario of "UE transmits UL WUS to NES Cell, UE obtains the UL WUS configuration from Cell A, UE receives on-demand SIB1 from NES Cell", the UE obtains the WUS configuration through Cell A and sends a WUS request on-demand SIB1 to the NES cell. When the UE obtains RAR or SIB1 in the NES cell (at this time, the UE has not completed the stay in the NES cell), the UE is still staying in Cell A. At this time, the UE can only receive paging through Cell A. Therefore, the UE may miss the paging on Cell A. Moreover, even if the NES cell can broadcast paging to the UE, since the UE has not completed the reception of SIB1, the UE cannot receive paging in the NES cell. Based on the relevant mechanism, when the network pages the UE in the cell where the UE last accessed but does not receive feedback, it will spread to other base stations to page the UE. Therefore, in this case, when the UE does not report on cell A or NES cell, the network may think that the UE is not there and instruct other base stations to send paging, increasing signaling overhead. In addition, whether the cell supporting on-demand SIB1 supports UE to receive paging, the relevant technology is also under discussion; from the perspective of energy saving, it can be considered that cell A assists in sending paging. Therefore, it is also necessary to design a mechanism for the UE to return to cell A to receive paging, so that the network and UE can determine the specific paging effective time and reduce the overhead of cell A.

[0184] Based on this, in various embodiments of the present application, the terminal (i.e., UE) sends indication information to the NG-RAN node associated with cell A, and the information is used to indicate that the terminal will obtain one or more of the on-demand SIB1 from the NG-RAN node associated with the NES cell, the terminal will leave cell A, the terminal will access the NES cell, and the terminal will obtain the on-demand SIB1 in the NES cell. In this way, for the above-mentioned scenario 2, since the network can promptly learn the specific situation indicated by the terminal, that is, it is known that the terminal will obtain the on-demand SIB1 from the NG-RAN node associated with the NES cell, the terminal will leave cell A, the terminal will access the NES cell, and the terminal will obtain the on-demand SIB1 in the NES cell, the network can subsequently perform paging based on the terminal's indication, such as paging the terminal by one or more of cell A, NES cell, and other cells within each time range of one or more specific time ranges, thereby reducing the situation where the terminal misses the network paging when obtaining the on-demand SIB1 in the NES cell, and can reduce the paging overhead of the network.

[0185] Specifically, the embodiment of the present application provides an information transmission method, which is applied to a terminal, such as Figure 1 As shown, the method includes:

[0186] Step 101: Send first information to a first network node, where the first information is used to indicate one or more of the following:

[0187] The terminal obtains the on-demand SIB1 from the second network node;

[0188] The terminal will leave the first cell;

[0189] The terminal will access the second cell;

[0190] The terminal will obtain the on-demand SIB1 in the second cell; wherein,

[0191] The first cell is associated with the first network node, the second cell is associated with the second network node, and the second cell includes a NES cell.

[0192] Here, it should be noted that, in various embodiments of the present application, cell A (i.e., the first cell) can be understood as an anchor; "one or more / one or more items" refers to at least one / at least one item, and "multiple / multiple items" refers to at least two / at least two items.

[0193] In actual application, the terminal may also be referred to as UE or user. In addition, the network node (i.e., the first network node and the second network node) may also be referred to as a network side node, a network device, a network side, a network, etc., and may specifically include an NG-RAN node, such as a base station, etc.; the embodiment of the present application does not limit the specific name and type of the network node, as long as its function is realized.

[0194] In actual application, the terminal will obtain the on-demand SIB1 from the second network node, and the terminal will obtain the on-demand SIB1 in the second cell. The obtaining of the on-demand SIB1 can also be understood as requesting / receiving / obtaining / collecting SIB1. In addition, the terminal can request / receive / obtain / collect SIB1 by sending WUS to the second network node; or, the terminal can request / receive / obtain / collect SIB1 by sending Msg1 / msgA or other information (these information can be recorded as second information in the subsequent description). The embodiment of the present application does not limit the specific method of the terminal requesting / receiving / obtaining / collecting SIB1.

[0195] In one embodiment, sending the first information to the first network node may include:

[0196] The first information is sent to the first network node at a first time, where the first time is separated from a second time by a first time length, and the second time includes one or more of the following:

[0197] A time point at which the terminal obtains the on-demand SIB1 from the second network node;

[0198] The time when the terminal sends the WUS to the second network node;

[0199] A moment when the terminal sends second information to the second network node, where the second information is used to request on-demand SIB1.

[0200] Here, it can be understood that, since the first information sent by the terminal at the first moment indicates the future action of the terminal (i.e., obtaining the on-demand SIB1 from the second network node, leaving the first cell, accessing the second cell, and obtaining the on-demand SIB1 in the second cell), and the terminal performs one or more of obtaining the on-demand SIB1 from the second network node, sending WUS to the second network node, and sending the second information to the second network node at the second moment, that is, the terminal obtains / requests / receives / obtains / receives the on-demand SIB1 at the second moment, so the first moment is before the second moment. In addition, in actual application, the first duration can be pre-defined on the terminal according to demand (such as the uplink propagation delay of the terminal sending a message to the first network node, etc.); or, the network can indicate the first duration to the terminal, for example, the third information broadcast by the first network node in the subsequent description can include the first duration.

[0201] In actual application, the terminal may send the first information to the first network node through a specific RACH resource (which may also be understood as a dedicated resource for the first information); in this way, the first network node may obtain the first information through the dedicated resource for the first information.

[0202] In one embodiment, if Figure 1 As shown, the method may also include:

[0203] Step 102: within a first time range, listen to a paging message sent by the second network node and / or the first network node, wherein the second time is a start time of the first time range.

[0204] Among them, in actual application, the duration of the first time range can be equal to the sum of the second duration, the third duration, and the fourth duration; the second duration represents the RAR window (which can be expressed as ra-response window in English); the third duration is equal to N multiplied by the fifth duration or the sixth duration, N is an integer greater than 0, the fifth duration represents the sending period of SI (such as on-demand SI) (which can be expressed as SI periodicity in English), and the sixth duration represents the monitoring window of SI (which can be expressed as monitor window in English); the fourth duration represents the camping latency (which can be expressed as camping latency in English).

[0205] In actual application, the size of N (i.e., the value of N) can be pre-defined on the terminal as required; or, the network can indicate the size of N to the terminal, for example, the third information broadcast by the first network node in the subsequent description can include the value of N. In addition, one or more of the second duration, the fourth duration, the fifth duration, and the sixth duration can be pre-set as required or indicated by the network, for example, the third information broadcast by the first network node in the subsequent description (i.e., the fifth information in the third information) can include one or more of the second duration, the fourth duration, the fifth duration, and the sixth duration.

[0206] In actual application, the second network node and / or the first network node may page the terminal within the first time range according to a specific paging repetition number (which can be expressed as paging repeated count or repeated number in English); in other words, when the number of times the second network node and / or the first network node sends a paging message to the terminal is equal to a specific paging repetition number (which can be understood as reaching a maximum paging repetition number), if neither the second network node nor the first network node receives feedback from the terminal (such as feedback of a message for establishing an RRC connection), it can be determined that the terminal has not established an RRC connection with the second network node or the first network node within the first time range, and the network needs to continue paging the terminal in a subsequent time. Among them, the paging repetition number can be an integer greater than 1, and the specific value of the paging repetition number can be pre-set according to demand, and the embodiment of the present application does not limit this.

[0207] Based on this, in one embodiment, the method may further include:

[0208] If no RRC connection is established with the second network node or the first network node within the first time range, within the second time range, listening to paging messages sent by one or more of the following network nodes:

[0210] the first network node;

[0211] A third network node, the third network node includes one or more network nodes except the first network node and the second network node; wherein,

[0212] The start time of the second time range is the end time of the first time range.

[0213] In actual application, when the terminal does not establish an RRC connection with the second network node or the first network node within the first time range, the first network node may instruct the second network node to send a paging message to the terminal within the second time range; specifically, the first network node may send the tenth information to the second network node, and the tenth information is used to instruct the second network node to send a paging message to the terminal within the second time range. In addition, the first network node may also instruct the third network node to send a paging message to the terminal within the second time range; specifically, the first network node may send the twelfth information to the third network node, and the twelfth information is used to instruct the third network node to send a paging message to the terminal within the second time range. In addition, the second network node may instruct the first network node to diffuse the paging message, that is, to instruct the first network node to send the twelfth information to the third network node; specifically, the second network node may send the thirteenth information to the first network node, and the thirteenth information is used to instruct the first network node to send the twelfth information to the third network node; after receiving the thirteenth information, the first network node may send the twelfth information to the third network node.

[0214] In actual application, the first network node / the second network node / the third network node may also page the terminal within the second time range according to a specific paging repetition number; in other words, within the second time range, the number of times the first network node / the second network node / the third network node sends a paging message to the terminal may be greater than or equal to 1 and less than or equal to the paging repetition number.

[0215] In actual application, when the second network node does not belong to the next paging area range of the terminal provided by the AMF, the first network node can send an eleventh message to the AMF, and the eleventh message is used to indicate that the second network node is added to the next paging area range of the terminal.

[0216] In actual application, before sending the first information to the first network node, the terminal may determine relevant configuration based on the network's instruction and / or local definition.

[0217] Based on this, in one embodiment, the method may further include:

[0223] Eighth information, the eighth information including the configuration information related to the on-demand SIB1 acquired by the terminal from the second network node;

The RAR reception-related configuration information of the second network node (i.e., the fifth information) may include one or more of the configurations such as RAR window (i.e., the second duration), SI sending period (i.e., the fifth duration), SI monitoring window (i.e., the sixth duration), etc. The sixth information and the seventh information may be expressed as the same field or different fields. The embodiment of the present application does not limit the specific content and specific expression form contained in the sixth information, the seventh information and the eighth information.

[0227] In actual application, before the first network node broadcasts the third information, the first network node may obtain the relevant configuration of the second network node through the Xn interface during the process of establishing Xn with the second network node or after the Xn establishment is completed. Specifically, the first network node may receive the ninth information sent by the second network node, and the ninth information may include one or more of the fourth information, the fifth information, the sixth information, and the eighth information. Here, the configuration (i.e., the ninth information) that the first network node and the second network node interact through the Xn interface can also be understood as the relevant configuration of the mechanism that can support the terminal to return to the first cell to receive paging.

[0295] In the information transmission method provided by the embodiment of the present application, the terminal sends first information to the first network node, and the first information is used to indicate one or more of the following: the terminal will obtain on-demand SIB1 from the second network node; the terminal will leave the first cell; the terminal will access the second cell; the terminal will obtain on-demand SIB1 in the second cell; wherein the first cell is associated with the first network node, the second cell is associated with the second network node, and the second cell includes an NES cell. In the scheme provided by the embodiment of the present application, the terminal sends indication information (i.e., the first information) to the NG-RAN node (i.e., the first network node) associated with cell A (i.e., the first cell), and the information is used to indicate that the terminal will obtain on-demand SIB1 from the NG-RAN node (i.e., the second network node) associated with the NES cell (i.e., the second cell), the terminal will leave cell A, the terminal will access the NES cell, and the terminal will obtain on-demand SIB1 in the NES cell. In this way, for the above scenario 2, that is, in "the terminal sends an uplink (UL) WUS to the NES cell, and the terminal obtains UL from cell A In the scenario of "WUS configuration, the terminal receives on-demand SIB1 from the NES cell", since the network can promptly learn the specific situation indicated by the terminal, that is, it is known that the terminal will obtain the on-demand SIB1 from the NG-RAN node associated with the NES cell, the terminal will leave cell A, the terminal will access the NES cell, and the terminal will obtain one or more of the on-demand SIB1 in the NES cell, the network can subsequently perform paging based on the terminal's indication, such as paging the terminal by one or more of cell A, NES cell, and other cells within each time range of one or more specific time ranges, thereby reducing the situation where the terminal misses the network paging when obtaining the on-demand SIB1 in the NES cell, and can reduce the paging overhead of the network.

[0296] The present application is described in further detail below in conjunction with application examples.

[0297] In this application example, the terminal is called UE, the first cell is called cell A, and the second cell is called NES cell; the communication of the first network node / the second network node / the third network node is referred to as the communication of cell A / NES cell / other cells.

[0298] This application example provides a terminal listening paging solution, which can include the following seven steps:

[0299] Step 1: Cell A obtains the relevant configuration of Msg1 / msgA of the NES cell (i.e., the fourth information mentioned above, which can also be understood as RACH configuration or WUS sending related configuration, such as one or more of preamble, RO and other configurations), RAR reception related configuration (i.e., the fifth information mentioned above, such as one or more of the configurations such as RAR window (i.e., the second duration mentioned above), SI (e.g., on-demand SI) sending cycle (i.e., the fifth duration mentioned above), SI monitoring window (i.e., the sixth duration mentioned above) and other configurations) during the process of establishing Xn with the NES cell or during the process of information exchange after the establishment of Xn, and then step 2 can be executed.

[0300] Step 2: Cell A broadcasts the on-demand WUS configuration information of the NES cell (i.e., broadcasts the above-mentioned third information). The broadcasted information may at least include the relevant configuration of Msg1 / msgA (i.e., the above-mentioned fourth information, which can also be understood as RACH configuration or WUS sending related configuration, such as one or more of the preamble, RO and other configurations), RAR reception related configuration (i.e., the above-mentioned fifth information, such as RAR window (i.e., the above-mentioned second duration), SI (such as on-demand SI) sending period (i.e., the above-mentioned fifth duration), SI monitoring window (i.e., the above-mentioned sixth duration) and other configurations), the offset value (offset, i.e., the above-mentioned first duration) of the uplink indication (which can be expressed as UL indication in English, i.e., the above-mentioned first information) sent by the UE to cell A before WUS is initiated, the indication of whether to listen to the paging of this cell after obtaining NES SIB1 (i.e., the above-mentioned seventh information), and other necessary configuration information (such as the value of N, on-demand SIB1 reception related configuration (i.e., the above-mentioned eighth information), etc.); then step 3 can be executed.

[0301] Step 3: Based on the protocol and / or the message broadcast by cell A (i.e., the third information above), the UE obtains relevant configurations, i.e., obtains the relevant configurations of Msg1 / msgA (i.e., the fourth information above), the relevant configurations of RAR reception (i.e., the fifth information above), the offset (i.e., the first duration above) of the uplink indication (i.e., the first information above) sent by the UE to cell A before WUS is initiated, whether to listen to the indication of paging of the cell after obtaining NES SIB1 (i.e., the seventh information above), and other necessary configuration information (such as the value of N, the relevant configurations of on-demand SIB1 reception (i.e., the eighth information above), etc.); then step 4 can be executed.

[0302] Step 4: Figure 4 As shown, before the UE sends an on-demand SIB1 request message (which may be WUS / Msg1 / msgA, i.e., WUS or the above-mentioned second information) to the NES cell, it sends indication information (i.e., the above-mentioned first information) to cell A at the offset time specified by the network (i.e., the above-mentioned first time). The sending of the indication information can be achieved through a specific RACH resource. Through the dedicated resource, cell A can learn that there is a UE in the current cell that will obtain SIB1 from the NES cell (and may leave the current cell). The configuration of the offset can take into account the uplink propagation delay of the UE sending the message to cell A.

[0303] Based on the offset (i.e., the first duration), cell A can determine the time t (i.e., the second time, i.e., the start time of the first time range) when the UE sends the SIB1 request message to the NES cell, and has the following two behaviors after t1 (t1=t+RAR window+N*SI sending period / monitoring window+residence delay, t1 is the end time of the first time range):

[0304] Behavior 1: Cell A may send RAN paging related information (i.e., the tenth information) to the NES cell for paging the UE in the NES cell, regardless of whether the NES cell belongs to the next paging area. At this time, cell A may not send RAN paging related information to other cells in the next paging area provided by the AMF to page the UE.

[0305] Behavior 2: after t1 (ie, within the second time range), the paging message is sent again on cell A. The number of times the paging message is sent may be any value in the range of [1, a specific number of paging repetitions].

[0306] Here, cell A can execute behavior 1 or behavior 2 alone; or, it can execute behavior 1 and behavior 2, such as executing behavior 1 first and then behavior 2, executing behavior 2 first and then behavior 1, or executing behavior 1 and behavior 2 at the same time; the specific execution method can be indicated by the network (such as indicated by step 2) or specified by the protocol. In addition, if the UE needs to return to cell A to listen to paging, the value of N can also be indicated by the network to the UE (such as indicated by step 2).

[0307] In actual application, behavior 1 and / or behavior 2 may occur when the network does not receive UE feedback (such as feedback message for establishing RRC connection) after sending the maximum number of paging messages according to a specific number of paging repetitions within [t, t1] (i.e., the first time range mentioned above), or when the NES cell indicates that cell A itself (i.e., the NES cell) does not send a paging message during the establishment or interaction of the Xn interface, but cell A sends a paging message (i.e., the sixth information indicates that the first network node needs to send a paging message to the terminal instead of the second network node). In addition, if the NES cell does not belong to the next paging area scope (which can be expressed as Next Paging AreaScope in English) provided by the AMF, cell A can indicate (which can be expressed as indicate in English) the AMF to add the NES cell to the scope, that is, cell A can send the eleventh information mentioned above to the AMF.

[0308] After step 4, one or more of the following steps 5 to 7 may be performed.

[0309] Step 5: After requesting and obtaining the on-demand SIB1 based on the network configuration and protocol provisions, the UE listens to paging in the NES cell or cell A, initiates access in the NES cell, and establishes an RRC connection;

[0310] Step 6: When the UE successfully accesses the NES cell, the NES cell notifies cell A that the UE has accessed;

[0311] Step 7: If paging is performed through the NES cell, when the UE still does not access after the NES cell has reached the maximum number of paging repetitions and the UE has not accessed (possibly due to UE movement or UE RACH failure, etc.), the NES cell can send an indication message (i.e., the thirteenth message mentioned above) to cell A, requesting cell A to diffuse the paging message, thereby avoiding additional power consumption of the NES cell due to paging diffusion.

[0312] The solution provided in this application example can reduce the situation where the UE misses the network paging when acquiring the on-demand SIB1 in the NES cell, and can reduce the network paging overhead; in addition, it can also reduce the sending of NES cell public signals (such as paging messages, etc.), thereby further improving the energy saving effect of the NES cell.
