Description

Technical Field

[0001] The embodiments of the present application relate to the field of communication technology, and in particular, to a communication method, device, and system. Background Art

[0002] In order to reduce the power consumption of the terminal, the network device may send a paging early indication (PEI) before the terminal's paging occasion (PO), and the PEI may indicate whether there is a paging message sent in the terminal's PO. The terminal may receive the PEI. When the PEI indicates that there is no paging message sent in the PO, the terminal does not receive the paging DCI after receiving the PEI. When the PEI indicates that there is a paging message sent in the PO, the terminal may continue to monitor the paging downlink control information (DCI). Since the power consumption required for receiving the PEI is lower than that for receiving the paging DCI, designing the PEI before sending the PO can reduce the power consumption of the terminal.

[0003] In actual applications, some terminals support the PEI feature, while some terminals do not. For terminals that support the PEI feature, before using PEI, their PEI features will be reported to the network device as capability information so that the network device can perform the paging process based on the terminal's capability information. However, when the terminal's capability information is reported, the capability information reported to the network device may be inaccurate due to network transmission quality or limited parsing capabilities of the device used to transmit the terminal's capability information (such as a base station) or other reasons. The network device's understanding of the terminal's paging capability is inconsistent with the terminal's actual paging capability, resulting in paging failure. Summary of the invention

[0004] The embodiments of the present application provide a communication method, device and system to solve the problem that the network equipment's understanding of the communication capability of a terminal (such as paging capability) is inconsistent with the actual communication capability of the terminal (such as actual paging capability), resulting in the failure of the communication process (such as paging).

[0005] In order to achieve the above purpose, the embodiment of the present application adopts the following technical solution:

[0006] In a first aspect, the present application provides a communication method, which can be executed by a terminal and a functional module or chip in the terminal. Taking terminal execution as an example, the terminal supports a first communication characteristic related to a first communication process. The method includes: the terminal receives first information sent by a network device when executing a first communication process, and when the first information matches the first communication characteristic related to the first communication process supported by the terminal, the first communication characteristic is enabled, and the first communication process is executed based on the first communication characteristic; otherwise, the first communication characteristic is not enabled.

[0007] Based on the method described in the first aspect, the terminal can receive the first information sent during the communication process, and determine whether the received first information matches the communication characteristics supported by the terminal. If they match, the first communication characteristics are effective and the first communication process is performed based on the first communication characteristics. In this way, it can be ensured that when the terminal side and the network side have a consistent understanding of the communication characteristics supported by the terminal, the two sides interactively perform the communication process to avoid failure of the communication process. For example, when the first communication process is a paging process and the first communication characteristic is a PEI characteristic, according to the method provided in the first aspect, it can be ensured that when the terminal side and the network side have a consistent understanding of the PEI characteristics supported by the terminal, the two sides interactively perform the paging process to avoid paging failure.

[0008] In one possible design, when the first information does not match the first communication characteristic, the first communication characteristic is not effective. The mismatch between the first information and the first communication characteristic means that the understanding of the first communication characteristic may be inconsistent between the terminal side and the network side. In this way, when the first information does not match the first communication characteristic and the understanding of the first communication characteristic may be inconsistent between the terminal side and the network side, the first communication characteristic is not effective, and the first communication process is executed according to the understanding of the network side device to ensure the successful execution of the first communication process. For example, when the first communication process is a paging process and the first communication characteristic is a PEI characteristic, based on this possible design, the paging process is executed according to the traditional paging method, such as not parsing PEI but directly parsing the paging message on PO, to avoid paging failure.

[0009] In one possible design, the terminal receives the first information from the network device, including: receiving the first information from the network device in the first stage, and performing a match verification on the first information received by the terminal and the first communication characteristic supported by the terminal. When the first information received by the terminal matches the first communication characteristic supported by the terminal, the first communication characteristic is effective in the second stage after the first stage, and the first communication process is performed based on the first communication characteristic. In this way, the terminal can be awakened in the first stage to receive the first information and perform a match verification. After verification, the communication characteristic is effective or ineffective in the second stage, and the matching verification stage and the effective / ineffective stage are clarified.

[0010] In one possible design, the first stage includes at least one communication cycle; or, the first stage is a preset stage; or, the first stage includes at least one communication sub-cycle. Among them, one communication cycle corresponds to one execution of the first communication process, and one communication cycle includes at least one communication sub-cycle. For example, when the first communication process is a paging process, the communication cycle is a paging cycle, and the communication sub-cycle is a paging frame (paging frame, PF). In this way, different time granularities can be used as the first stage, and the first stage can be designed flexibly and diversifiedly.

[0011] In one possible design, the start time of the first phase is determined according to the moment when the terminal supports the first communication characteristic. For example, when the first communication process is a paging process and the first communication characteristic is a PEI characteristic, the first phase can be started after the terminal determines that it supports the PEI characteristic, such as starting the first phase at any time after the terminal determines that it supports the PEI characteristic. In this way, the start time of the first phase is specified, so that the terminal is ready to receive the first information at this moment and verify whether the first information accurately matches the communication characteristics supported by the terminal.

[0012] In a possible design, a times threshold (or a limited matching times threshold) and / or a matching duration can be designed, and the times threshold and / or the matching duration can be used to control the terminal to verify whether the first information and the first communication characteristic match, so as to avoid the problem of inaccurate matching results due to occasional verification matching situations, and / or to avoid long-term verification affecting the power consumption of the terminal. Specifically, the first information matches the first communication characteristic, including the number of times the first information matches the first communication characteristic being greater than or equal to the set times threshold; in this way, the first information is determined to match the first communication characteristic only when multiple verifications are matched, so as to avoid the problem of inaccurate matching results due to occasional verification matching situations; and / or, a third stage (or matching duration) is specified, and the first information is verified to match the first communication characteristic within the third stage. If the third stage times out and does not match, no verification is performed, so as to avoid long-term verification affecting the power consumption of the terminal. The third stage is set as the stage threshold for verifying whether the first information matches the first communication characteristic, and the duration of the third stage is less than or equal to the duration of the first stage.

[0013] In one possible design, the first communication characteristic includes a PEI characteristic, and the first communication process includes a paging process. Based on this possible design, the communication method described in this application can be applied to the paging process, and the terminal supports the PEI characteristic in the application scenario. In the paging process, the method described in this application can also be used to achieve a consistent understanding of the PEI characteristic of the terminal by the terminal side and the network side device, thereby ensuring the normal execution of the paging process.

[0014] In one possible design, the first information includes PEI, paging DCI, and second information of a paging message; PEI is used to indicate whether the terminal needs to parse the second information, paging DCI is used to indicate whether the paging DCI schedules a paging message, and the paging message is used to indicate which terminals are paged. In this way, the specific contents of the first information in the paging scenario are limited, providing a basis for the terminal to verify the first information.

[0015] In one possible design, when the first communication characteristic includes the PEI characteristic, if the PEI indicates that the terminal needs to parse the second information, and the paging message indicates that the terminal is paged, the first information matches the first communication characteristic. Conversely, if the PEI indicates that the terminal does not need to parse the second information, but the paging message indicates that the terminal is paged, the first information does not match the first communication characteristic. In this way, two situations in which the first information matches or does not match the PEI characteristic in the paging scenario are specified, so that the terminal determines whether to take effect the PEI characteristic based on these two situations.

[0016] In a possible design, the PEI in the first information and the second information are parsed synchronously; and / or, the PEI in the first information is not parsed, and the second information is parsed. For example, the PEI in the first information and the second information are parsed in each cycle in the first stage, or the first action (synchronous parsing of the PEI in the first information and the second information) and the second action (not parsing the PEI in the first information, parsing the second information) are alternately executed / intervally executed in the first stage. In this way, the parsing process of the terminal is flexible and diversified. When the PEI in the first information and the second information are parsed in each cycle in the first stage, the terminal can be guaranteed to achieve matching verification and improve matching verification efficiency. When the first action (synchronous parsing of the PEI in the first information and the second information) and the second action (not parsing the PEI in the first information, parsing the second information) are alternately executed / intervally executed, not only can the terminal be intermittently woken up to parse the PEI characteristics and verify whether the first information matches the PEI characteristics, further reducing the power consumption of the terminal, but also when the terminal is paged, the terminal can use the traditional paging method to find out whether it is paged as soon as possible, thereby improving the paging efficiency.

[0017] In one possible design, the first communication characteristic includes an enhanced discontinuous reception (extended DRX, eDRX) characteristic; the first communication process includes a paging process. Based on this possible design, the communication method described in this application can be applied to paging based on the eDRX characteristic, and the paging based on the eDRX characteristic can also use the method described in this application to achieve a consistent understanding of the eDRX characteristic of the terminal by the terminal side and the network side device, and ensure the normal execution of the paging process under the premise of reducing the power consumption of the terminal.

[0018] In one possible design, the first information includes a paging message; when a paging message is received in a DRX manner, it is determined that the first information does not match the first communication characteristic. Conversely, when a paging message is not received in a DRX manner, it is determined that the first information matches the first communication characteristic; wherein, not receiving a paging message in a DRX manner includes: not receiving a paging message within a preset duration after the arrival of a DRX cycle, and / or not receiving a paging message within a preset number of times. In this way, when the terminal side and the network side have a consistent understanding of the eDRX characteristics of the terminal, eDRX is enabled to further reduce the power consumption of the terminal.

[0019] In one possible design, DRX is discontinuous reception, and the length of the DRX cycle can be set as needed, for example, it can be set to 10.24s, that is, the terminal is in a dormant state during the 10.24s and does not receive data, saving power consumption. eDRX extends the length of DRX, and the eDRX length is a multiple of the DRX length. eDRX can further save the power consumption (or power consumption) of the terminal.

[0020] In a second aspect, the present application provides a communication device, which may be a terminal or a chip or system on chip in a terminal, or a functional module in a terminal for implementing the first aspect or any possible design of the method in the first aspect. The communication device can implement the functions performed by the terminal in the above aspects or possible designs, and the functions can be implemented by hardware executing corresponding software. The hardware or software includes one or more modules corresponding to the above functions. For example, the communication device may include a sending unit, a receiving unit, and a processing unit. Among them, the sending unit is used to send capability information, and the capability information is used to indicate that the terminal supports a first communication characteristic, and the first communication characteristic is related to a first communication process; the receiving unit is used to receive first information, and the first information is information sent by a network device when executing a first communication process; the processing unit is used to validate the first communication characteristic when the first information matches the first communication characteristic, and execute the first communication process based on the first communication characteristic.

At the same time, the execution actions of each unit of the communication device may refer to the first aspect or any possible design of any possible design of the first aspect, and no further details are given.

[0039] Before introducing the embodiments of the present application, some technical terms involved in the embodiments of the present application are explained. It should be noted that the following explanations are intended to make the embodiments of the present application easier to understand and should not be regarded as limiting the scope of protection required by the embodiments of the present application.

[0040] Paging: The network side equipment will send a paging message to a terminal in an idle or inactive state at a calculated paging occasion (PO), and the terminal will receive the paging message on the same PO. This process can be called paging, which can achieve the purpose of paging (or waking up) a specific terminal under the network. Paging supports discontinuous reception (DRX), so that the terminal can wake up only within a fixed time to receive paging messages, and can sleep for the rest of the time to reduce power consumption and increase battery life. The cycle of each paging is the DRX cycle. There are several paging frames (PF) in a DRX cycle. One PF corresponds to several POs. A terminal only needs to receive paging messages on a certain PO.

[0041] The system frame number (SFN) of the PF used for paging and the sequence number i_s of the PO can be obtained by using the following formulas (1) and (2):

[0042] (SFN+PF_offset)mod T=(T div N)*(UE_ID mod N) Formula (1)

[0043] i_s=floor(UE_ID / N)mod Ns formula (2)

[0044] Among them, PF_offset, DRX cycle T, the number of PFs in the DRX cycle N, and the number of POs in a PF Ns in the above formula can be called paging parameters. PF_offset is an offset value used to determine the PF. PF_offset can be pre-defined by the protocol or determined by the access network device and configured to the terminal. T is the DRX cycle, which can also be called the paging cycle. N is the number of PFs in the DRX cycle T, and Ns is the number of POs in a PF. "mod" represents the remainder obtained by dividing the two numbers before and after mod. floor() is rounded down. "*" is multiplication calculation. "div" is division calculation. (SFN+PF_offset)mod T=(T div N)*(UE_ID mod N) means that all terminals are divided into N groups according to UE_ID. The value of UE_ID mod N can be used to determine which group the terminal is in and which PF it corresponds to. floor(UE_ID / N)mod Ns is equivalent to further dividing the terminal corresponding to a PF into Ns groups. According to the value of floor(UE_ID / N)mod Ns, the group to which the terminal specifically corresponds, that is, the PO, can be determined. Among them, the value of UE_ID can be the 5G-S temporary mobile subscriber identity (5G-S-temporary mobile subscriber identity, 5G-S-TMSI) mod 1024 of the terminal. It should be understood that in the embodiment of the present application, the DRX cycle T, the number of PFs in the DRX cycle N, and the number of POs in a PF Ns can be dynamically configured as needed or pre-determined by the protocol without restriction.

[0045] For example, Figure 1 The paging process is shown in FIG. Figure 1As shown, the paging process may include: a core network device (such as an access and mobility management function (AMF)) sends a paging message to an access network device (such as a base station) through a next generation access point (NGAP) interface. The paging message may be called an NGAP paging message. The paging message carries a terminal paging record list, and the terminal paging list includes the terminal's 5G-S-TMSI. (2) After receiving the NGAP paging message, the access network device can calculate the specific PF and PO positions according to the paging parameters and the terminal's 5G-S-TMSI, and send the scrambled paging PDCCH and paging PDSCH to the terminal at the PF and PO positions. (3) The terminal calculates the PF and PO positions for paging according to the terminal's 5G-S-TMSI, and uses its own paging radio network temporary identifier (paging-radio network temporary identifier) ​​at this moment. The terminal uses the paging DCI to descramble the paging PDCCH and monitor the paging DCI. If the paging DCI is detected and the paging DCI indicates that the PDSCH carrying the paging message is scheduled, the terminal receives the paging PDSCH carrying the paging message at the resource position indicated by the paging DCI, and determines whether it has been paged according to the paging message carried by the paging PDSCH. For example, if the paging message received by the terminal carries its own identity information, it determines that it has been paged, otherwise, it has not been paged.

[0046] However, paging for terminals in idle or inactive states may result in false alarms, i.e., after receiving and decoding a paging message, the terminal finds that it has not actually been paged by the network. One of the main reasons for false alarms is that there are multiple terminals monitoring the same PO. According to the above calculation formulas (1) and (2), although the 5G-S-TMSIs allocated under a core network may be different, the UE_ID may be the same, and the PO positions calculated by different terminals may be the same. In addition, under the existing paging mechanism, when a terminal receives a paging DCI, it only obtains the scheduling information of the paging message, but cannot know whether the paging message is for itself. The terminal can only determine whether the paging is for the terminal according to the terminal identification information in the paging message after receiving and decoding the paging message on the paging PDSCH. Therefore, when multiple terminals monitor the same PO, if a paging is only for some of the terminals, then for the terminals that are not actually paged, there is unnecessary paging reception, resulting in unnecessary power consumption.

[0047] In order to further reduce the power consumption of the terminal, an eDRX mechanism is proposed. eDRX extends the length of DRX (or the length of the DRX cycle), which is a multiple of the DRX length. Receiving paging messages based on eDRX can further reduce the power consumption of the terminal. The length of eDRX requires the terminal and the network device to be implemented based on the following handshake negotiation process: the terminal sends a request message to the network device, requesting to configure eDRX for the terminal, the network device receives the request message, and in response to the request message, sends a response message to the terminal, the response message indicates the length of eDRX configured for the terminal, the terminal receives the response message, and sends a completion message to the network device, indicating that the configuration of the length of eDRX is completed, the network device receives the completion message, and in response to the completion message, sends an acknowledgement (ACK) to the terminal.

[0048] In addition, in order to reduce the probability of false alarms in paging, a user equipment (UE) grouping mechanism is proposed. User equipment can be represented as a terminal. The basic idea of ​​the UE grouping mechanism is to group the terminals that monitor the same PO, that is, to divide the terminals on the same PO into different UE subgroups. When paging, a paging early indication (PEI) is set, and the PEI indicates the number of POs targeted by this paging and the UE subgroups on each PO. Before receiving the paging PDCCH and paging PDSCH, the UE can know whether it needs to receive a paging message on the PO this time, reducing the probability of the terminal receiving and decoding paging messages unnecessarily, thereby reducing the power consumption generated by the terminal decoding paging PDCCH and paging PDSCH that are not its own.

[0049] PEI (paging early indicator): PEI is indicated to the UE through the format DCI2-7 PDCCH. PEI can indicate whether the UE subgroup needs to monitor the paging PDCCH and paging PDSCH in several POs after the time domain position of PEI and in each PO, or it can be understood that PEI indicates whether the terminal needs to parse the paging PDCCH and paging PDSCH on the PO. Figure 2 Schematic diagram of PEI paging process is shown in FIG. Figure 2 As shown, one PO corresponds to M UE subgroups, and the PEI carries M binary bits corresponding to the PO, and the M binary bits correspond to the M UE subgroups. The binary bit "1" indicates that the UE subgroup on the PO needs to monitor the paging PDCCH and the paging PDSCH, and the binary bit "0" indicates that the UE subgroup on the PO does not need to monitor the paging PDCCH and the paging PDSCH. For example, Figure 2In the figure, UE1 and UE4 are UE subgroup 1 of the first PO. Through the first subgroup of the M subgroups to which the first PO belongs in the PEI, the indication is "1", indicating that UE1 and UE4 need to monitor PDCCH at the first PO position. After decoding the paging DCI, they decode PDSCH (paging message) according to the scheduling information indicated by the paging DCI. UE2 and UE3 are UE subgroup 2 of the first PO. Through the second subgroup of the M subgroups to which the first PO belongs in the PEI, the indication is "0", indicating that UE2 and UE3 do not need to monitor PDCCH at the first PO position.

[0050] Among them, when the terminal accesses the cell, it can determine whether the cell supports the PEI feature and whether to monitor PEI in the cell according to the system information of the cell. For example, a new pei-Config-r17 information element is added to the system information block 1 (SIB) 1, such as the lastUsedCellOnly-r17 information element. When the lastUsedCellOnly-r17 information element exists in the SIB1 of the current cell, the terminal needs to determine whether to monitor PEI according to whether the current cell is its last used cell (last used cell). Specifically, the last used cell of the terminal may be: the cell of the radio resource control release (RRC release) message that the terminal recently received that does not contain the noLastCellUpdate-r17 information element. If the noLastCellUpdate-r17 information element exists in the RRC release message, the last used cell for PEI is not updated, otherwise, it is updated to the current cell. For example, the terminal first resides in cell 1 that supports PEI paging and is in a connected state. However, the cell where the terminal resides will change as the terminal moves. When the terminal needs to reside in cell 2, the terminal will receive the system information SIB1 of cell 2, in which the following situations may occur: Situation 1: When the noLastCellUpdate-r17 information element exists in the radio resource control release message (RRC release) sent by cell 1 to the terminal, the terminal does not need to make a judgment, and the terminal directly monitors PEI in cell 2 because the last used cell has not changed. Situation 2: If the lastUsedCellOnly-r17 information element does not exist in the system information SIB1 sent by cell 2 to the terminal, the terminal can monitor PEI in cell 2. Situation 3: When the lastUsedCellOnly-r17 information element exists in the system information SIB1 sent by cell 2 to the terminal, and the noLastCellUpdate-r17 information element does not exist in the radio resource control release message (RRC release) sent by cell 1 to the terminal, the terminal only monitors PEI in cell 2. It should be understood that this example is based on the existing protocol, such as the R17 protocol version, and determines whether the PEI feature is effective in the current cell based on the pei-Config-r17 information element and lastUsedCel lOnly-r17. Subsequently, as the protocol expands or the standard evolves, whether the PEI feature is effective in the current cell can also be determined based on other factors without limitation.

[0051] As can be seen from the above, the PEI-based paging process reduces the power consumption of the terminal. For a terminal supporting the PEI feature, the terminal hopes to report its ability to support the PEI feature to the network device so that the network side device performs the PEI-based paging process based on the terminal capability information. Figure 3 , Figure 4 The flowcharts of the terminal accessing the cell and reporting its own capability information are shown respectively. Figure 3 As shown in FIG. 1 , it is a schematic diagram of a process in which a terminal accesses a cell in a connected state. Figure 3 As shown, it may include:

[0052] S301. After completing the cell search and finding a candidate target cell, the terminal obtains system information to confirm whether to stay in the cell.

[0053] Among them, the system information is a message sent by the access network device, which contains the information required for terminal initialization and some other function / feature related information. The basic process for idle and inactive terminals to obtain system information is that the terminal first obtains the master information block (MIB), obtains SIB1 based on the scheduling information in the MIB, and then obtains other SIBs based on the scheduling information in SIB1.

[0054] The system information is divided into minimum system information (minimum SI) and other system information (other SI).

[0055] Among them, the minimum system information consists of MIB and SIB1. SIB1 is also called the remaining minimum system information (RMSI). MIB is broadcast periodically on the broadcast channel (BCH). SIB1 is broadcast periodically on the downlink shared channel (DL-SCH) or sent to the connected terminal through dedicated signaling. Other system information consists of other SIBs, such as SIB2-SIB9. Other SIBs are broadcast periodically on DL-SCH or on-demand on DL-SCH, that is, when a terminal in an idle or inactive state requests a certain SIB, the network broadcasts the SIB, otherwise the SIB is not sent, or it is sent to the connected terminal through dedicated signaling.

[0056] Among them, SIB1 configures the default paging cycle T, the number of PFs in the paging cycle (N) and the PF offset (PF_offset), the number of POs corresponding to one PF (Ns) and other paging parameters.

[0057] S302: The terminal executes a random access procedure and enters a connected state from an idle state.

[0058] Exemplarily, after completing the cell search and obtaining the system message, the terminal resides in a cell. Thereafter, the terminal performs a random access procedure (or an initial access procedure), and enters a connected state after the random access procedure is completed.

[0059] Specifically, Figure 3 As shown, S302 may include the following processes:

[0060] 1) The terminal requests to establish a new connection in the idle state, for example, the terminal sends an RRC establishment request to the access network device.

[0061] 2) The access network equipment exchanges signaling with the terminal to complete the RRC establishment process.

[0062] 3) The terminal sends a setup completion message carrying the first NAS message to the network device through the access network device.

[0063] 4) Other NAS messages are exchanged between the terminal and the network device.

[0064] 5) The network device sends the user context of the terminal to the access network device.

[0065] Exemplarily, a network device (such as AMF) prepares the user context of the terminal (including PDU session context, security keys, terminal radio capabilities, terminal security capabilities, etc.) and sends it to the access network device.

[0066] 6) The access network equipment activates the security of the application server (AS) through the terminal.

[0067] 7) The access network equipment establishes SRB2 and DRB.

[0068] Specifically, the access network device performs reconfiguration to set SRB2 and DRBs for the terminal, or to set SRB2 and optional DRBs for the IAB-MT.

[0069] 8) The access network device indicates that the network device establishment process has been completed.

[0070] Furthermore, after the terminal enters the connected state, optionally, if the network device needs to query the terminal's capabilities, the network device initiates a terminal capability query process. The purpose of reporting terminal capabilities is to tell the network device which networks, graphics cards, capabilities, etc. the terminal supports.

[0071] like Figure 4 As shown, the terminal capability query process may include:

[0072] S401. A network device (such as AMF) sends an initial context setup request (Inital Context Setup Reqeust) to an access network device.

[0073] Exemplarily, the network device may send an initial context establishment request to the access network device via the NGAP interface.

[0074] The initial context establishment request is used to request to establish the context of the terminal. The initial context establishment request may carry the identifier of the terminal.

[0075] S402: When the initial context establishment request does not include any capability information of the terminal, the access network device initiates a terminal capability query message (or RRC UE Capability Enquiry message) to the terminal.

[0076] The terminal capability query message is used to instruct the terminal to report its own capability information.

[0077] S403: After receiving the terminal capability query message, the terminal reports its capability information to the access network device by carrying it in UE capability information (or called RRC UE Capability Information).

[0078] S404: The access network device receives and analyzes the UE capability information of the terminal, and sends the UE capability information of the terminal to the network device. The network device receives and stores the received UE capability information of the terminal.

[0079] It should be noted that as long as the terminal does not leave the control range of the network device, the network device will always save the capability information of the terminal. When the above terminal needs to access the network device again, and the network device has saved the capability information of the terminal, the network device will bring the previously saved UE capability information to the access network device, and then the access network device will not send the terminal capability query message to the terminal again. Therefore, whether the terminal is required to report capability information depends on whether the network device has saved the terminal capability information. For example, there may be RRC UE Capability Enquiry message and RRC UECapability Information in the signaling log, or there may be no such pair of signaling messages. When there is no such pair of signaling messages, it means that the network device has saved the capability information of the terminal, and the network device only needs to directly schedule resources with the access network device.

[0080] exist Figure 4In the capability information query process shown in the figure, after the access network device receives the capability information of the terminal, in addition to transmitting all the capability information of the terminal to the network device (such as the core network device), it also parses the capability information related to paging in the terminal capability information and transmits it separately to the network device (or core network device) so that the core network device can use it when paging the terminal. For example, as shown in Table 1 and Table 2 below. Table 1 is a part of the terminal wireless capability information indication. This message is sent by the 5G wireless access network node and is used to provide the authentication management with information related to the terminal radio capability. It can be seen from the content in the table that the message does not necessarily need to carry the terminal's wireless capability for paging. Please refer to TS 38413.9.3.1.68 protocol configuration. Table 2 is part of the content contained in the terminal wireless capability information indication signaling, including the signaling of the terminal wireless capability used for 5G paging. For detailed definition, see TS 38.331

[0084]

[0085] However, based on the existing protocol architecture, during the interaction between the terminal and the network device, the protocol versions supported by the terminal and the network device may be different. The access network device with a lower version cannot parse the capability information of the terminal with a higher version, and thus cannot accurately transmit the capability information of the terminal to the core network. However, for the terminal, the terminal only knows that it has reported the capability information of a higher version, but cannot confirm whether the core network knows the capability information of the terminal, resulting in inconsistent understanding of the capability information of the terminal between the terminal and the core network, causing the failure of information interaction.

[0086] Taking the paging process as an example, when the capability information is PEI capability, the terminal is not sure about the version / feature support of the access network device when reporting its own PEI capability. The access network device that has not been upgraded to support PEI features cannot interpret the PEI capability of the terminal, and thus cannot put the PEI capability reported by the terminal into the terminal paging capability and forward it to the core network. Therefore, when the core network device pages a terminal, the terminal paging capability pushed to each access network device participating in the paging will not include the PEI capability of the terminal. The terminal cannot know the above situation, and the terminal will think that it has reported the PEI capability. Therefore, after the terminal enters the idle state or the inactive state, it will use the PEI feature in the cell that supports PEI, but the access network device of the cell will not use PEI to page the terminal because it cannot obtain the PEI capability information of the terminal, which causes the terminal to monitor PEI but the access network device will not send PEI to the terminal, so that the terminal may not be paged, resulting in the problem of paging failure.

[0087] For example, in one scenario, the terminal supports the PEI feature and supports UE_ID grouping. The terminal reports the capability information of supporting the PEI feature to the access network device A. The access network device A receives the capability information of the terminal, which includes the capability information related to paging (or called paging capability information). However, the access network device A cannot parse the PEI feature of the high-version terminal and does not support the PEI feature. The paging capability information of the terminal reported to the core network device does not include the PEI feature of the terminal. The core network device receives the capability information related to paging of the terminal and sends a paging configuration message that does not include PEI and corresponds to the traditional paging method to the access network device B. The access network device B further sends the paging configuration information to the terminal. Access network device B supports the PEI feature.

[0088] In this scenario, the terminal believes that it has reported the PEI feature and the received paging message should also be a paging message indicated by PEI. Therefore, the PEI feature is used to parse the paging message. However, since access network device A does not support the PEI feature, the PEI grouping that the terminal thinks is inconsistent with the PEI grouping information configured by the network setting. That is, the network device does not include the terminal when using the PEI indication for the corresponding group, which may cause the terminal to parse more unnecessary POs and waste power, or parse less necessary POs and lose paging.

[0089] For example, in another scenario, the terminal supports the PEI feature and supports UE_ID grouping, but the terminal signal is not good. The terminal reports the capability information of supporting the PEI feature to the access network device A. The access network device A supports the PEI feature. The access network device A transmits all the paging-related capability information (or paging capability information) in the received terminal capability information to the core network device. The core network device receives the paging capability information of the terminal and sends the corresponding paging configuration message to the access network device B. The access network device B further sends the paging configuration information to the terminal. Among them, the core network device supports the PEI feature and optionally supports the core network device grouping mode, and the access network device B supports the PEI feature.

[0090] In this other scenario, although the terminal reports the PEI feature, and the network equipment (such as access network equipment, core network equipment) supports the PEI feature and supports the UE_ID grouping method (or core network equipment grouping), the PEI feature can be effective. However, the terminal may have a poor signal problem when receiving related paging messages, which may easily lead to incorrect parsed information when receiving and parsing DCI 2-7 carrying PEI from the network equipment, thereby causing the terminal to use PEI indication inaccurately, and the terminal may parse more unnecessary POs and waste power consumption, or parse less necessary POs and lose paging.

[0091] In addition, when the terminal supports the eDRX feature (or called eDRX capability), if the terminal does not receive the last ACK during the process of the terminal and the network device negotiating the length of eDRX based on the following handshake, the terminal cannot determine whether the network device did not receive the completion message, or received the completion message but the terminal did not receive the ACK sent. In this scenario, the terminal has two options: enable the eDRX feature, and receive paging messages based on the eDRX feature to further reduce power consumption, but if the network device does not support the eDRX feature, the terminal may lose paging; or, the terminal does not enable the eDRX feature, and receives paging messages according to the DRX feature, wasting the power consumption of the terminal.

[0092] To solve the problem that when the terminal supports the PEI feature, unnecessary POs are parsed more and power consumption is wasted, or necessary POs are parsed less and paging is lost due to inconsistent understanding between the terminal and the network side, or to solve the problem that when the terminal supports the eDRX feature, the terminal loses paging or wastes power consumption of the terminal due to inconsistent understanding between the terminal and the network side. The present application provides a communication method, which includes: the terminal receives a first message sent by a network device when executing a first communication process, and when the first information matches a first communication characteristic related to the first communication process supported by the terminal, the first communication characteristic is activated, and the first communication process is executed based on the first communication characteristic, otherwise, the first communication characteristic is not activated. That is, the entire communication process is divided into a running-in period and a trust period, and different trust periods are selected according to the situation of the running-in period, such as activating or not activating the first communication characteristic.

[0093] Taking the PEI feature as an example, during the running-in period, the terminal first parses the paging messages on the PEI and PO. If the PEI matches the paging message on the PO, the PEI is effective. If they do not match, the PEI is not effective. Taking the eDRX feature as an example, the terminal can try to parse the paging message in both the DRX mode and the eDRX mode. If the paging is parsed in the DRX mode, the verification fails and the eDRX feature cannot be effective; otherwise, the eDRX feature can be considered to be effective after a period of time. It should be understood that the present application is not limited to the PEI feature and the eDRX feature in the paging process as an example, and describes the technical solution that the PEI feature and the eDRX feature are effective only when the terminal side and the network side have a consistent understanding of the terminal's PEI capability. For other communication processes, this method can also be referred to. After the terminal side and the network side have a consistent understanding, certain communication characteristics of the communication process can be effective.

[0094] The communication method provided in the embodiment of the present application is described below in conjunction with the accompanying drawings.

[0095] The communication method provided in the embodiment of the present application can be used in any of the fourth generation (4G) systems, long term evolution (LTE) systems, fifth generation (5G) systems, new radio (NR) systems, NR-vehicle-to-everything (V2X) systems, and Internet of Things systems, and can also be applied to other next generation communication systems, etc., without limitation. Figure 5 Taking the communication system shown as an example, the communication method provided in the embodiment of the present application is described.

[0096] Figure 5 is a schematic diagram of a communication system provided in an embodiment of the present application, such as Figure 5 As shown, the communication system may include core network equipment, access network equipment (such as access network equipment 1 and access network equipment 2) and terminals. The core network equipment and the access network equipment may be referred to as network equipment, the terminal may be located within the coverage of the network equipment, and the terminal may be connected to the network equipment through a Uu port. Figure 5 In the present invention, the terminal can be in an idle or inactive state, the network device can periodically page the terminal in the idle or inactive state, and the terminal in the idle or inactive state can periodically monitor whether it is paged. If it is paged, it switches to a connected state and communicates with the network device through the Uu port. The terminal can support one or more of the PEI feature and the eDRX feature.

[0097] It should be noted that Figure 5 This is just an exemplary framework diagram. Figure 5 The number of nodes included in the is not limited, for example, more terminals can be included, and Figure 5 In addition to the functional nodes shown, other nodes may also be included, such as core network equipment, gateway equipment, application servers, etc., without limitation. Figure 5 Each network element in the system is described.

[0098] Among them, the core network equipment can be a control plane network function unit, such as AMF, which is responsible for the central point of most control plane function interactions, and is mainly used for registration management, connection management, access management, mobility management, security and access management, and various authorization-related functions.

[0099] The access network device is mainly used to implement functions such as resource scheduling, wireless resource management, and wireless access control of the terminal. Specifically, the access network device can be any node in a small base station, a wireless access point, a transmission receive point (TRP), a transmission point (TP), and some other access nodes. In the embodiment of the present application, the device for implementing the function of the access network device can be an access network device, or it can be a device that can support the access network device to implement the function, such as a chip system (such as a processing system composed of one chip or multiple chips) or a modem. The following takes the device for implementing the function of the access network device as an example, which is an access network device, to describe the method provided in the embodiment of the present application.

[0100] The terminal may be a terminal equipment (terminal equipment) or a user equipment (user equipment, UE) or a mobile station (mobile station, MS) or a mobile terminal (mobile terminal, MT), etc. Specifically, the terminal may be a mobile phone, a tablet computer or a computer with a wireless transceiver function, or a virtual reality (virtual reality, VR) terminal, an augmented reality (augmented reality, AR) terminal, a wireless terminal in industrial control, a wireless terminal in unmanned driving, a wireless terminal in telemedicine, a wireless terminal in a smart grid, a wireless terminal in a smart city, a smart home, a vehicle-mounted terminal, etc. In the embodiment of the present application, the device for realizing the function of the terminal may be a terminal, or may be a device that can support the terminal to realize the function, such as a chip system (e.g., a processing system composed of a chip or multiple chips) or a modem. The following takes the device for realizing the function of the terminal as an example to describe the communication method provided in the embodiment of the present application.

[0101] In specific implementation, the wireless protocol stack between the terminal and the access network equipment is divided into two planes, namely the user plane and the control plane. The user plane (UP) protocol stack is the protocol cluster used for user data transmission, and the control plane (CP) protocol stack is the protocol cluster used for system control signaling transmission. The protocol stack between the terminal and the core network equipment includes the control plane protocol stack. Figure 6 As shown, the protocol stack between the terminal and the access network device may include: radio resource control, packet data convergence protocol, radio link control layer protocol, media access control, physical layer. The protocol stack between the terminal and the core network device may include the non-access layer. The following describes each layer:

[0102] Non-access stratum (NAS): handles the transmission of information between the terminal and the core network equipment. The content of the transmission can be user information or control information. For example, the establishment and release of services or mobility management information. Below the NAS layer, we call it the AS layer, and NAS is transparent to the access network equipment. Figure 6 As you can see, the access network equipment does not have this layer of protocol. All NAS messages are not perceived by the access network equipment. The access network equipment forwards NAS messages without parsing them. NAS is built on the AS layer. It has nothing to do with access information. It only establishes a signaling channel between the terminal and the core network equipment through the signaling interaction of the access layer, so that the non-access layer signaling process can be carried out. The NAS sublayer terminates at the core network equipment.

[0103] Radio resource control (RRC): The most critical signaling protocol that supports multiple functions between terminals and access network equipment, such as broadcasting NAS layer and AS layer system messages, paging function, RRC connection establishment, maintenance and release, end-to-end radio bearer establishment, modification and release, mobility management including terminal measurement report, cell handover, terminal cell selection and reselection, etc. The RRC layer protocol terminates at the access network equipment.

[0104] Packet Data Convergence Protocol (PDCP): Responsible for performing header compression to reduce the bit flow that must be transmitted by the radio interface. The PDCP layer performs integrity checks on RRC and NAS layer messages on the control plane, but not on the user plane. As well as encryption of data and signaling.

[0105] Radio link control layer protocol (Radio Link Control, RLC): responsible for segmentation and connection, retransmission processing, and sequence control of high-level data. RLC proposes three modes: transparent mode (transparent mode, TM), unacknowledged mode (unacknowledged mode, UM) and acknowledged mode (acknowledged mode, AM). In general, AM mode is used for TCP services, such as file transfer, which are mainly concerned with the uninterrupted transmission of data; UM mode is used for high-level sequential transmission of data, but does not retransmit lost PDUs, and is typically used for Voip services, which are mainly concerned with transmission delays; TM mode is only used for special purposes, such as random access.

[0106] Media access control (MAC): responsible for handling hybrid automatic repeat request (HARQ) retransmission and uplink and downlink scheduling. For the entire product, the speed can be reflected if retransmission and scheduling are done well.

[0107] Physical Layer (PHY): Responsible for processing encoding and decoding, modulation and demodulation, multi-antenna mapping, and other telecommunication physical layer functions. It is the most complex layer and also the layer of protocol that tests the product the most. In actual design, it involves many algorithms and can best reflect the performance of the actual chip. It is closely related to the hardware and needs to work together.

[0108] Combine the following Figure 5 The communication system shown in the figure describes the communication method provided in the embodiment of the present application. In the following embodiments, each device may have Figure 6 The protocol stack shown in the figure, and the actions, terms, etc. involved in each embodiment can refer to each other, and the message name or parameter name in the message exchanged between devices in each embodiment is only an example, and other names can also be used in specific implementations. For example, the "correspondence" in the following embodiments can be replaced by "association", etc.

[0109] Figure 7 A communication method provided in an embodiment of the present application, such as Figure 7 As shown, the method may include:

[0110] S701. A terminal interacts with a network device using a first communication characteristic supported by the terminal.

[0111] The terminal can be Figure 5 In the communication system shown in the figure, the network device may be an access network device, and the access network device may be Figure 5 The access network device 1 in the communication system shown establishes an RRC connection with a terminal.

[0112] In one example, the first communication characteristic supported by the terminal in the interaction between the terminal and the network device may include: the terminal may receive capability query information from the access network device, and send capability information indicating that the terminal supports the first communication characteristic to the access network device. Accordingly, the access network device receives the capability information. The access network device parses the capability information sent by the terminal, and reports the capability information of the terminal to the core network device.

[0113] The capability query information can be used to query the capability information of the terminal, and the terminal sends the capability information in response to the capability query information. Figure 4The corresponding embodiments are described and will not be described in detail here. The capability information can be used to indicate that the terminal supports the first communication characteristic, and the first communication characteristic can be related to the first communication process. The capability information can be called the capability information of the terminal. Specifically, the capability information of the terminal can include but is not limited to the PEI characteristic, the first communication process can be a paging process, and can also include other capability information, such as the information type of the terminal specified in the 3GPP protocol TS38413.9.2.13.1, the wireless capability of the terminal, etc.

[0114] Specifically, the access network device may parse part of the capability information sent by the terminal, such as parsing capability information related to paging (or called paging capability information), and report all the parsed capability information to the core network device.

[0115] In this application, the protocol versions supported by the access network device and the terminal may be the same or different. For example, the protocol version supported by the access network device may be the same as the protocol version supported by the terminal; or, the protocol version supported by the access network device may be lower than the protocol version supported by the terminal.

[0116] It should be understood that, affected by the protocol version and / or the communication quality between the terminal and the access network device, the capability information reported by the access network device to the core network device may be the same as or different from the capability information sent by the terminal to the access network device in S701 to indicate that the terminal supports the first communication feature. For example, one possible situation is: the capability information sent by the terminal to the access network device in S701 to indicate that the terminal supports the first communication feature includes the PEI feature supported by the terminal, but the access network device cannot parse whether the terminal supports the PEI feature because its own protocol version is lower than the protocol version of the terminal. Therefore, the capability information of the terminal reported by the access network device to the core network device is that the PEI feature is not supported, resulting in the capability information of the terminal reported by the access network device to the core network device being different from the capability information sent by the terminal to the access network device in S701 to indicate that the terminal supports the first communication feature. Another possible situation is that the protocol version supported by the terminal in S701 and the access network device in S701 is the same. Then the capability information sent by the terminal in S701 to the access network device to indicate that the terminal supports the first communication characteristic includes the terminal supporting the PEI characteristic, and the access network device correctly parses out that the terminal supports the PEI characteristic. Therefore, the capability information of the terminal reported by the access network device to the core network device is the same as the capability information sent by the terminal in S701 to the access network device to indicate that the terminal supports the first communication characteristic.

[0117] In this application, for the purpose of distinction, the capability information sent by the terminal to the access network device in S701 to indicate that the terminal supports the first communication characteristic may be referred to as the first capability information, and the capability information sent by the access network device to the core network device may be referred to as the second capability information. Among them, it is unknown whether the capability information about the terminal carried in the first capability information matches the capability information about the terminal carried in the second capability information. Because the second capability information is obtained by the access network device according to the configuration of its own device and the protocol parsing the first capability information reported by the terminal. When the protocol configuration of the access network device is lower than the protocol configuration of the terminal, the access network device is affected by the protocol configuration and cannot parse the first capability information sent by the terminal. The access network device generates the second capability information from the reported capability information of the terminal according to its own configuration and reports it to the core network device. Further, after the core network device receives the second capability information carrying the terminal capability information, the access network device saves the second capability information and uses the second capability information as the capability information of the terminal. Subsequently, when the core network device determines to execute the first communication process, the core network device sends the configuration information related to the first communication process to the access network device based on the saved second capability information.

[0118] In another example, the first communication feature supported by the interactive terminal between the terminal and the network device can be implemented based on the following handshake negotiation process: the terminal sends a request message to the network device, requesting to configure the first communication feature (such as eDRX) for the terminal, the network device receives the request message, and in response to the request message, sends a response message to the terminal, the response message indicates that the first communication feature and related information, such as the length of eDRX, are configured for the terminal, the terminal receives the response message, and sends a completion message to the network device, indicating that the configuration is completed, the network device receives the completion message, and in response to the completion message, sends a confirmation ACK to the terminal. If the terminal does not receive the last ACK in the process where the terminal and the network device need to negotiate the length of eDRX based on the following handshake, the terminal cannot determine whether the network device did not receive the completion message, or received the completion message but the ACK sent was not received by the terminal. In this scenario, the terminal has two options: the eDRX feature is enabled, and paging messages can be received based on the eDRX feature to further reduce power consumption, but if the network device does not support the eDRX feature, the terminal may lose paging; or the terminal does not enable the eDRX feature, and receives paging messages according to the DRX feature, wasting the power consumption of the terminal.

[0119] S702: The network device executes a first communication process and sends first information to the terminal.

[0120] In one example, a core network device determines to execute a first communication process, and sends configuration information related to the first communication process to an access network device based on the second capability information. The access network device receives the configuration information related to the first communication process, generates first information according to the configuration information related to the first communication process, and sends the first information to the terminal. Taking the first communication process as a paging process as an example, when the configuration information indicates PEI characteristics and UE_ID grouping, the first information includes PEI, paging DCI, and paging information. Or when the configuration information does not indicate the PEI characteristics, the first information does not include PEI, and the first information includes paging DCI and paging information.

[0121] Among them, the configuration information related to the first communication process may include information related to the first information, such as the monitoring period of the first information, the time-frequency resource information corresponding to the first information, the grouping information, etc. Taking the first communication process as a paging process as an example, the configuration information related to the first communication process may be called a paging parameter or paging configuration information, and the configuration information may specifically include: whether to support the PEI feature, the grouping mode, PF_offset, the DRX cycle T, the number of PFs in the DRX cycle N, and the number of POs in a PF Ns One or more.

[0122] Among them, since the terminal has mobility, inter-cell movement may occur, and the cell where the terminal is currently located and the cell where the terminal is located when reporting capability information may be the same cell, or different cells under the same access network device, or different cells under different access network devices. Taking the inter-cell movement of the terminal as an example, the access network device in S702 may be access network device 1, or may be the access network device corresponding to the cell where the terminal is currently located, such as access network device 2, etc., without limitation.

[0123] S703: The terminal receives first information sent by the network device.

[0124] The network device may be an access network device.

[0125] Exemplarily, in the first stage, the terminal may receive first information sent by the network device.

[0126] In the present application, the first stage may be referred to as a running-in period. The first stage includes at least one communication cycle, and one communication cycle corresponds to executing the first communication process once; or, the first stage is a preset stage; or, the first stage includes at least one communication sub-cycle in a communication cycle, and one communication cycle corresponds to executing the first communication process once, and one communication cycle includes at least one communication sub-cycle. Taking the first communication process as a paging process as an example, the first stage may include at least one paging cycle; or, it is preset to a certain paging stage; or, it includes at least one PF cycle. Among them, the paging cycle corresponds to the time required to execute a paging process, and a paging cycle includes at least one PF cycle.

[0127] In this application, the start time of the first phase is determined according to the moment when the terminal supports the first communication characteristic. The first phase can be started after the terminal determines that it supports the first communication characteristic. Taking the first communication process as the paging process and the first communication characteristic as the PEI characteristic as an example, for a terminal that supports PEI paging, the running-in period can be entered at any time, regardless of whether the network device supports PEI.

[0128] Further, the terminal may receive the first information in the first stage, and verify whether the first information matches the first communication characteristic.

[0129] The first communication characteristic is a PEI characteristic, and the first information matches the first communication characteristic, including: PEI indicates that the terminal parses the paging message on the PO, and the paging message on the PO indicates that the terminal is paged. If the PEI indicates that the terminal does not parse the paging message on the PO, but the paging message on the PO indicates that the terminal is paged, it means that the first information does not match the first communication characteristic.

[0130] Wherein, the first communication characteristic is an eDRX characteristic, and the first information matches the first communication characteristic including: a situation where a paging message is not received in a DRX manner. Wherein, the situation where a paging message is not received in a DRX manner includes: the paging message is not received within a preset duration after the DRX cycle arrives, and / or the paging message is not received within a preset number of times. If the terminal receives a paging message in a DRX manner, the first information does not match the first communication characteristic.

[0131] In one example, the verification of whether the first information matches the first communication characteristic is not limited by the number of verifications and the verification time. After one verification is passed, the first information is considered to match the first communication characteristic. For example, taking the first communication characteristic as the PEI characteristic as an example, once there is a PEI indicating that the terminal parses the paging message on the PO, and the paging message on the PO indicates that the terminal is paged, it is determined that the first information matches the first communication characteristic, otherwise, it does not match. Taking the first communication characteristic as the eDRX characteristic as an example, once the terminal receives the paging message in the DRX mode, it is determined that the first information does not match the first communication characteristic.

[0132] In another example, in the present application, a number threshold (or a limited matching number threshold) and / or matching duration can be designed, and the number threshold and / or matching duration can be used to control the terminal to verify whether the first information and the first communication characteristic match, so as to avoid the problem of inaccurate matching results due to occasional verification matching situations, and / or to avoid long-term verification affecting the power consumption of the terminal. Specifically, the first information matches the first communication characteristic including: the number of times the first information matches the first communication characteristic in the first stage is greater than the set number threshold; and / or, in the third stage, the first information matches the first communication characteristic, and if the third stage times out and there is no match, no verification is performed.

[0133] The number threshold can be set as needed and is not limited. When the number of matches is greater than the set number threshold, the match is considered to be credible, that is, the first information and the first communication characteristic are indeed matched, and the first communication characteristic can be effective. In this way, the first information and the first communication characteristic are determined to match only when multiple verifications are matched, avoiding the problem of inaccurate matching results due to occasional verification matches;

[0134] Among them, the duration of the third stage is set to be less than or equal to the duration of the first stage, which can be understood as a matching stage limit. If the third stage times out and there is no match, no verification will be performed to avoid long-term verification affecting the power consumption of the terminal.

[0135] Taking the first communication process as a paging process and the first communication characteristic as a PEI characteristic as an example, the first information matches the PEI characteristic including: the number of times the first information matches the PEI characteristic in the first stage is greater than the set number threshold; and / or, in the third stage, the first information matches the PEI characteristic, and if the third stage times out and does not match, no further verification is performed, and it is determined that the first information does not match the PEI characteristic. For example, the first stage is preset to 10s, the third stage is 8s, and the matching threshold is N. When the number of times the first information matches the PEI characteristic is greater than or equal to N within 10s, and / or, within the set third stage of 8s, the first information matches the PEI characteristic successfully, it means that the terminal can perform the paging process based on the PEI characteristic.

[0136] Taking the first communication process as a paging process and the first communication characteristic as the eDRX characteristic as an example, the matching of the first information with the eDRX characteristic includes: The terminal does not receive a paging message in the DRX mode. For example, if the terminal does not receive a paging message within a preset duration after the DRX cycle arrives, and / or within a preset number of times, it is considered that the first information matches the eDRX characteristic, and then the eDRX characteristic takes effect. If the terminal receives a paging message in the DRX mode, it is considered that the first information does not match the eDRX characteristic but matches the DRX characteristic, and then the DRX characteristic can take effect.

[0137] Among them, the preset duration and the preset number of times can be set according to needs without limitation.

[0138] Suppose the DRX cycle is 10.24 s, the eDRX cycle is 102.4 s, which is 10 times the DRX cycle, and the preset duration and the preset number of times are M (10.24 s < M < 102.4 s) and N (1 < N < 10) respectively. When the first information still fails to receive a paging message within the preset duration M in the DRX mode and / or within the preset number of times N in the DRX mode, it means that the terminal can perform the paging process based on the eDRX characteristic. In this way, in the case of failing to receive a paging message multiple times and / or for a long time in the DRX mode, it is determined that the first information matches the eDRX characteristic, avoiding the problem of inaccurate matching results caused by occasional verification matching situations.

[0139] S704. When the first information matches the first communication characteristic, the terminal enables the first communication characteristic and performs the first communication process based on the first communication characteristic.

[0140] S705. When the first information does not match the first communication characteristic, the terminal does not enable the first communication characteristic.

[0141] As can be seen from the above description, when the number of times the first information matches the first communication characteristic in the first stage is less than the set number threshold, and / or in the third stage, the first information does not match the first communication characteristic, it is a situation where the first information does not match the first communication characteristic.

[0142] Taking the first communication process as a paging process and the first communication characteristic as the PEI characteristic as an example, the preset first stage is 10 s, the third stage is 8 s, and the matching threshold is N. When the number of times the first information matches the first communication characteristic is less than N within 10 s, and / or within the set third stage of 8 s, the first information still fails to match successfully, the terminal does not enable the PEI.

[0143] Taking the first communication process as the paging process and the first communication characteristic as the eDRX characteristic as an example, assuming that the DRX cycle is 10.24s and the eDRX cycle is 102.4s, which is 10 times the DRX cycle, when the first information receives the paging message in the DRX manner, the first information does not match the eDRX characteristic, and the eDRX characteristic is not effective for the terminal.

[0144] based on Figure 7 In the method shown, when it is uncertain whether the protocol versions between the terminal and the network device are equal and / or whether the communication quality between the terminal and the access network device is good, the terminal can report the communication characteristics related to a certain communication process supported by itself, and then judge the matching of the first information and the first communication characteristics during the running-in period to select whether to take effect in the future based on the first communication characteristics. The first communication process. Specifically, the terminal receives the first information sent during the communication process, and determines whether the received first information matches the communication characteristics supported by the terminal. If they match, the first communication characteristics are effective and the first communication process is executed based on the first communication characteristics. In this way, it can be ensured that when the terminal side and the network side have a consistent understanding of the communication characteristics supported by the terminal, the two interact to execute the communication process to avoid the failure of the communication process. Through this process, the terminal can adaptively choose to execute the first communication process based on the first communication characteristics or execute the first communication process in a traditional manner, which can not only obtain the benefits brought by executing the first communication process based on the first communication characteristics (such as reducing power consumption), but also reduce the probability of communication failure in the first communication process. For example, when the first communication process is a paging process and the first communication characteristic is a PEI characteristic, according to the method provided in the first aspect, it can be ensured that when the terminal side and the network side have a consistent understanding of the PEI characteristics supported by the terminal, the two sides interactively execute the paging process to avoid paging failure.

[0145] The following takes the first communication process as a paging process and the first communication characteristic as a PEI characteristic as an example. Figure 8 The above method is introduced in detail.

[0146] Figure 8 A flow chart of another communication method provided by the present application is as follows: Figure 8 As shown, the method may include:

[0147] S801. An RRC connection is established between the terminal and access network device 1, and the terminal is in a connected state.

[0148] The terminal supports the PEI feature, or it can be understood that the terminal has the PEI capability.

[0149] Specifically, the terminal can determine whether it supports the PEI feature according to whether the system message of the current cell contains the information element lastUsedCellOnly-r17 and whether the current cell of the terminal is the last used cell. The specific determination method can refer to the above and will not be described in detail.

[0150] S802: Access network device 1 sends capability query information to the terminal.

[0151] Exemplarily, the access network device 1 may send capability query information to the terminal via an RRC connection.

[0152] The capability query information may be called UE capability Enquiry, and the capability query information may be used to query the capability information of the terminal.

[0153] S803 . The terminal receives the capability query information and sends capability information 1 to access network device 1 .

[0154] The capability information 1 may be used to indicate that the terminal supports the PEI feature or that the terminal has the PEI capability. In addition, the capability information 1 may also indicate other capabilities of the terminal without limitation.

[0155] S804. Access network device 1 receives and parses capability information 1, and sends capability information 2 to the core network device.

[0156] The content indicated by the capability information 2 and the content indicated by the capability information 1 may be the same or different.

[0157] In one example, the protocol version supported by the terminal and the access network device 1 is the same, or the protocol version supported by the access network device 1 is higher than the protocol version supported by the terminal. At this time, the access network device 1 supports the parsing of the PEI capability, and can correctly and completely parse and extract the content of the capability information 1 to generate the capability information 2, and send it to the core network device. In this example, the content of the capability information 2 is the same as that of the capability information 1, and the capability information 2 also indicates that the terminal supports the PEI feature.

[0158] In another example, the protocol versions supported by the terminal and the access network device 1 are different, and the protocol version supported by the access network device 1 is lower than the protocol version supported by the terminal. At this time, the access network device 1 does not support the parsing of PEI capabilities, and cannot correctly and completely parse and extract the content of capability information 1. For example, the access network device may parse and extract part of the content in capability information 1, generate capability information 2 based on the extracted part of the content, and send it to the core network device. In this example, because the access network device 2 cannot parse and obtain the PEI feature supported by the terminal, the generated capability information 2 does not indicate that the terminal supports the PEI feature, that is, the PEI capability of the terminal cannot be reported to the core network device.

[0159] S805. The core network device receives capability information 2 and saves capability information 2, for example, in the context of the terminal.

[0160] Subsequently, the terminal enters an idle state or an inactive state from a connected state, and during the time when the terminal is in the idle state or the inactive state, the terminal may move, for example, move between cells or move within a cell.

[0161] S806: The core network device determines the paging terminal and sends the context of the terminal to the access network device 2.

[0162] The context of the terminal includes capability information of the terminal: capability information 2.

[0163] Further, the core network device supports the PEI feature, and the core network device can also indicate the core network grouping result to the access network device 2, such as indicating the paging group to be paged to the access network device 2. It should be understood that if the access network device 1 supports the parsing of the PEI capability, and the capability information 2 indicates the PEI capability of the terminal, the terminal described above participates in the paging grouping of the core network device. If the access network device 1 does not support the parsing of the PEI capability, and the capability information 2 does not indicate the PEI capability of the terminal, the terminal described above does not participate in the paging grouping of the core network device.

[0164] The access network device 2 is the access network device corresponding to the cell where the terminal is currently located, and the access network device 2 may be the same as the access network device 1 or different from the access network device 1 without limitation. The access network device 2 supports the PEI feature.

[0165] S807. Access network device 2 receives the context of the terminal, sends first information to the terminal based on the context of the terminal, and pages the terminal.

[0166] The first information includes PEI and second information, and the second information includes paging PDCCH and paging PDSCH. In the present application, paging PDCCH can carry paging DCI, and PEI indicates whether the terminal parses the second information on the PO corresponding to the paging group where the terminal is located. The paging DCI carried in the paging PDCCH is used to schedule the paging PDSCH, and the paging PDSCH carries the paging message, which is used to indicate the terminal being paged.

[0167] In one example, the access network device 1 does not support the resolution of PEI capabilities, and the capability information 2 does not indicate the PEI capabilities of the terminal. The terminal described above does not participate in the paging grouping of the core network device. However, since the terminal uses UE_ID grouping, if other terminals in the UE_ID group where the terminal is located support PEI capabilities and are paged this time, the PEI corresponding to the UE_ID grouping indicates the resolution of PO. At this time, the terminal needs to resolve the PO corresponding to the UE_ID grouping based on the PEI indication, but in fact, the network side does not include this terminal when the corresponding grouping uses the PEI indication, which causes the terminal to resolve unnecessary POs. If other terminals in the UE_ID group where the terminal is located support PEI capabilities and no terminal in this UE_ID grouping is paged, the PEI corresponding to the UE_ID grouping indicates that the PO is not resolved. At this time, the terminal does not resolve the PO. Although the terminal is paged at the group granularity on the PO, the terminal may be paged on the PO, which will cause the terminal to resolve less necessary POs and fail to lose.

[0168] In another example, the access network device 1 supports the resolution of PEI capabilities, and the capability information 2 indicates the PEI capability of the terminal. Then the terminal described above participates in the paging group of the core network device, but due to the poor channel quality between the terminal and the access network device 2, the terminal signal is not good, resulting in an error in resolving the PEI. For example, the PEI indicating the resolution of PO is identified as not resolving PO. At this time, if the terminal is paged on the PO, but the terminal does not resolve the PO, the terminal will fail to resolve the necessary PO. For another example, the PEI indicating the non-resolution of PO is identified as the resolution of PO, but the UE is not paged on the PO, which causes the terminal to resolve unnecessary POs.

[0169] S808: The terminal receives the first information and verifies whether the first information matches the PEI characteristics supported by the terminal. If yes, S809 is executed; otherwise, S810 is executed.

[0170] In the present application, the time period for verifying whether the first information matches the PEI characteristics supported by itself can be referred to as the PEI initial period or running-in period. Specifically, a first stage can be configured, which can be referred to as the PEI initial period or running-in period. The terminal can receive the first information in the first stage and verify whether the received first information matches the PEI characteristics supported by itself.

[0171] The first stage may be a time period of duration, and the time period may include at least one cycle (or verification cycle). Specifically, the first stage may be a pre-time period, or the first stage may include at least one paging frame, such as one paging frame or multiple paging frames, and one paging frame may be regarded as a verification cycle; or the first stage may include at least one paging cycle, such as one paging cycle or multiple paging cycles, and one paging cycle may be regarded as a verification cycle. No limitation is given.

[0172] In one example, after receiving the first information, the terminal can simultaneously parse the PEI and the PO, verify the content indicated by the PEI and the content indicated by the PO, and then determine whether the first information matches the PEI characteristics supported by itself according to the verification results.

[0173] It should be understood that parsing PO in the present application may refer to parsing the paging PDCCH and the paging PDSCH on the PO. In this example, the PEI in the first information and the PO may be parsed in each verification cycle in the first stage.

[0174] In another example, in the first stage, the first action and the second action are performed alternately, the first action is to parse PEI and PO simultaneously, and the second action is to parse PO without parsing PEI.

[0175] For example, in a possible design of this example, PEI and PO can be parsed in the first verification cycle, and PEI is not parsed in the second verification cycle, but PO is parsed. Optionally, the method can be repeated with reference to this method. The first verification cycle and the second verification cycle can be adjacent verification cycles or spaced verification cycles, without limitation.

[0176] For example, in another possible design in this example, PEI may not be parsed but PO may be parsed in the third verification cycle, and PEI and PO may be parsed simultaneously in the fourth verification cycle. Optionally, the execution may be repeated with reference to this method. The third verification cycle and the fourth verification cycle may be adjacent verification cycles or spaced verification cycles without limitation.

[0177] In the present application, the content of the verification PEI indication and the content of the PO indication may include: if the PEI indication in a certain verification period resolves the PO, and the paging message sent on the PO indicates that the terminal is paged, then the verification is passed in this verification period; conversely, if the PEI indication resolves the PO, but the paging of this terminal cannot be resolved according to the PEI resolution of the PO, this is a normal situation, because there may be paging of other terminals in the same group as this terminal, and the verification is not passed in this verification period. If the PEI indication does not resolve the PO, but the paging of this terminal is resolved on the PO, it is also a verification failure. If the PEI indication does not resolve the PO, but the paging of this terminal cannot be resolved after resolving the PO, it is impossible to determine whether it is abnormal. It may be that the terminal is not assigned to the group corresponding to the PO, or it may be that the terminal does not have a corresponding paging at this position.

[0178] In the present application, a number threshold (or a limited matching number threshold) and / or a matching duration can be set, and the number threshold and / or the matching duration are used to control the terminal to verify whether the first information and the first communication characteristic match, so as to avoid the problem of inaccurate matching results caused by occasional verification matching situations, and / or to avoid long-term verification affecting the power consumption of the terminal. Specifically, if the number of times the verification is passed is greater than or equal to the set number threshold, it means that the first information matches the PEI characteristics supported by itself, otherwise, it does not match. Alternatively, if there is at least one verification pass within a preset duration, such as the duration of the third stage, it means that the first information matches the PEI characteristics supported by itself, otherwise, from the beginning to the end of the third stage, it has not been verified, which means that the first information does not match the PEI characteristics supported by itself. Alternatively, within the duration of the third stage, there is a verification pass and the number of times the verification is passed is greater than or equal to the number threshold, which means that the first information matches the PEI characteristics supported by itself, otherwise, it means that the first information does not match the PEI characteristics supported by itself.

[0179] S809: The terminal takes effect of the PEI feature and parses the PO according to the PEI indication.

[0180] For example, Figure 9a As shown, if the verification passes multiple times in the first stage, such as 1 time or N times, the PEI will take effect. In the second stage, the PO is parsed according to the PEI indication. For example, when the PEI indicates that there is paging on the PO, the PO is parsed. When the PEI indicates that there is no paging on the PO, the PO is not parsed.

[0181] S810: The terminal does not take effect on the PEI feature and directly parses PO in a traditional manner.

[0182] For example, Figure 9b As shown, if multiple verifications fail in the first stage, for example, 1 or M verifications fail, the PEI will not be effective. In the second stage, according to the traditional method, the PEI is not parsed but the PO is parsed.

[0183] based on Figure 8 The method shown, when the first communication process is a paging process and the first communication characteristic is a PEI characteristic, by judging the matching situation between the paging message on the PO and the PEI characteristic during the running-in period, selects whether to take effect in the subsequent paging process based on the PEI characteristic. Specifically, the terminal receives the paging message on the PO sent during the paging process, and determines whether the received paging message on the PO matches the PEI characteristic supported by the terminal. If it matches, the PEI characteristic is effective and the paging process is executed based on the PEI characteristic. In this way, it can be ensured that when the terminal side and the network side have a consistent understanding of the PEI characteristic supported by the terminal, the two interact to execute the paging process to avoid the failure of the paging process. Through this process, the terminal can adaptively choose to execute the paging process based on the PEI characteristic or execute the paging process in a traditional way, which can not only obtain the benefits brought by executing the paging process based on the PEI characteristic (such as reducing power consumption), but also reduce the probability of communication failure during the paging process.

[0184] The method described in this application can be applied to the PEI feature in the R17 power reduction feature, and the power reduction scheme is effective under the premise of ensuring the normal function of paging. Using this scheme, it is possible to avoid the problem that the terminal may not support the PEI feature and cannot obtain the power consumption benefit brought by the PEI feature. At the same time, it is possible to avoid the problem that the PEI information parsed by the terminal is inaccurate when the terminal supports the PEI feature, resulting in the terminal losing the paging. In addition, in this application, the small power consumption of the additional PEI parsing during a period of running-in period is exchanged for the power consumption benefit of the subsequent long-term PEI feature taking effect.

[0185] The above mainly introduces the solution provided by the embodiment of the present application from the perspective of interaction between each node. It is understandable that each node, such as a terminal, a network device, etc., in order to realize the above functions, includes a hardware structure and / or software module corresponding to each function. It should be easily appreciated by those skilled in the art that, in conjunction with the algorithm steps of each example described in the embodiments disclosed herein, the present application can be implemented in the form of hardware or a combination of hardware and computer software. Whether a function is executed in the form of hardware or computer software driving hardware depends on the specific application and design constraints of the technical solution. Professional and technical personnel can use different methods to implement the described functions for each specific application, but such implementation should not be considered to exceed the scope of the present application.

[0186] The embodiment of the present application can group the functional modules of the terminal, network equipment, etc. according to the above method example. For example, each functional module can be grouped according to each function, or two or more functions can be integrated into one processing module. The above integrated module can be implemented in the form of hardware or in the form of software functional modules. It should be noted that the grouping of modules in the embodiment of the present application is schematic and is only a logical functional grouping. There may be other grouping methods in actual implementation.

[0187] Fig.10 The structure diagram of a communication device 100 is shown. The communication device 100 may be a terminal, or a chip in a terminal, or a system on a chip. The communication device 100 may be used to perform the functions of the terminal involved in the above embodiments. As an implementation method, Fig.10 The communication device 100 shown includes: a receiving unit 1001, a processing unit 1002, and a sending unit 1003;

[0188] The receiving unit 1001 is used to exchange the first communication feature supported by the terminal with the network device and receive the first information sent by the network device. For example, the receiving unit 1001 can support the communication device 100 to execute S701 and S703.

[0189] The processing unit 1002 is configured to determine whether the first information sent by the access network device matches the first communication feature supported by the communication device 100. If the first information matches the first communication feature, the communication device 100 is instructed to perform the first communication process based on the first communication feature; if the first information does not match the first communication feature, the communication device 100 is instructed to perform the first communication process without taking effect on the first communication feature. For example, the processing unit 1002 can be used to support the communication device 100 to perform S704 or S705.

[0190] The sending unit 1003 is configured to exchange the first communication feature supported by the terminal with the network device. For example, the sending unit 1003 may support the communication apparatus 100 to execute S701.

[0191] Among them, the relevant description of the first communication feature, the first communication process, and the first information supported by the interactive terminal with the network device can refer to that described in the above method embodiment.

[0192] For example, the first communication feature supported by the terminal for interaction with the network device is PEI, the first communication process is a paging process, the first information is sent by the access network device to the terminal based on the second capability information, wherein the second capability information is uploaded to the core network after the access network device parses the first capability information, wherein the first capability information is capability information sent by the terminal to the access network device to indicate that the terminal supports the first communication feature. As mentioned above, the situations where the first capability information and the second capability information carry the first communication feature are not necessarily the same, and the two can be the same or different. Because whether the first capability information carries the first communication feature is set according to the protocol / version supported by the terminal, and whether the second capability information carries the first communication feature is obtained by the access network device parsing the terminal capability information according to the protocol / version supported by itself.

[0193] Specifically, in the first stage, after the terminal receives the first information sent by the access network device, the following two situations will occur. In situation 1, when the first information matches the first communication feature, the terminal takes effect on the first communication feature and performs the first communication process based on the first communication feature. In situation 2, when the first information does not match the first communication feature, the terminal does not take effect on the first communication feature.

[0194] Specifically, in one possible design, the verification of whether the first information matches the first communication characteristic is not limited by the number of verifications and the verification time. After one verification is passed, the first information is considered to match the first communication characteristic. In another possible design, a number threshold (or a limited matching number threshold) and / or a matching duration can be designed, and the number threshold and / or the matching duration can be used to control the terminal to verify whether the first information matches the first communication characteristic, so as to avoid the problem of inaccurate matching results due to occasional verification matching situations, and / or to avoid long-term verification affecting the power consumption of the terminal.

[0195] Specifically, the start time of the first phase is determined according to the moment when the terminal supports the first communication feature, and the first phase can be started after the terminal determines that it supports the first communication feature. The first phase includes at least one communication cycle, or the first phase is a preset duration; or the first phase includes at least one communication sub-cycle in a communication cycle. Among them, one communication cycle corresponds to executing the first communication process once, and one communication cycle includes at least one communication sub-cycle.

[0196] Specifically, the above Figure 7 All relevant contents of each step involved in the illustrated method embodiment can be referred to the functional description of the corresponding functional module, and will not be repeated here. The communication device 100 is used to execute Figure 7 The method shown has the function of the terminal in the communication method shown, so it can achieve the same effect as the above communication method.

[0197] As another possible way to achieve this, Fig.10 The communication device 100 shown includes: a processing module and a communication module. The processing module is used to control and manage the actions of the communication device 100. For example, the processing module can integrate the functions of the processing unit 1002, and can be used to support the communication device 100 to execute S704 or S705 and other processes of the technology described herein. The communication module can integrate the functions of the receiving unit 1001 and the sending unit 1003, and can be used to support the communication device 100 to execute S704 or S705 and communicate with other network entities, such as with Figure 5 The communication device 100 may also include a storage module for storing program codes and data of the communication device 100.
