Description

Random access initiation method, communication device, and storage medium Technical Field

[0001] The present disclosure relates to the field of communication technology, and in particular to a random access initiation method, communication equipment, communication system, and storage medium. Background Art

[0002] With the development of communication technology, cell-discontinuous transmission (cell-DTX) and cell-discontinuous reception (cell-DRX) have been proposed. When cell-DTX is activated, the cell will perform downlink transmission during the cell-DTX activation period and will not perform downlink transmission during the cell-DTX inactive period. When cell-DRX is activated, the cell will perform uplink reception during the cell-DRX activation period and will not perform uplink reception during the cell-DRX inactive period, thereby achieving cell energy saving. Cell energy saving can also be called network energy saving (NES). In some cases, the cell can achieve network energy saving through intermittent sleep.

[0020] Embodiments of the present disclosure provide a random access initiation method, a communication device, a communication system, and a storage medium.

[0021] In a first aspect, a random access initiation method is provided, which is executed by a terminal and includes: determining whether to initiate a random access triggered by a first service based on the configuration of at least one of discontinuous transmission DTX and discontinuous reception DRX of at least one serving cell of the terminal.

[0022] Based on the above scheme, the terminal will determine whether to initiate random access triggered by the first service according to the configuration of at least one of the discontinuous transmission DTX and discontinuous reception DRX of at least one serving cell, rather than uniformly initiating random access when there is a first service transmission, thereby reducing unnecessary random access of the terminal, and also reducing network power consumption caused by the cell exiting DTX and / or DRX due to unnecessary random access of the terminal, and / or transmission delay of the first service.

[0023] In some embodiments of the first aspect, whether to initiate random access triggered by the first service is determined based on the configuration of at least one of discontinuous transmission DTX and discontinuous reception DRX of at least one serving cell of the terminal, including at least one of the following: when at least one serving cell of the terminal is not configured with DTX and DRX, determining not to initiate random access triggered by the first service; when at least one serving cell of the terminal is configured with at least one of DTX and DRX, determining whether to initiate random access triggered by the first service based on the activation status of at least one of DTX and DRX configured in at least one serving cell of the terminal.

[0024] Based on the above solution, when at least one serving cell of the terminal is not configured with DTX and DRX, it means that at least one serving cell of the terminal can operate normally, so the terminal can perform the transmission of the first service on the cell, and therefore there is no need to perform random access initiated by the first service.

[0025] In the case that the serving cell of the terminal is configured with DRX and / or DRX, it can be further determined whether it is necessary to initiate random access triggered by the first service according to the activation status of DRX and / or DRX.

[0026] In some embodiments of the first aspect, at least one service cell includes a primary cell (Pcell) and a secondary cell (Scell); the cell group in which the primary cell is located is a master cell group (MCG); determining whether to initiate random access triggered by a first service according to the configuration of at least one of discontinuous transmission DTX and discontinuous reception DRX of at least one service cell of the terminal, including at least one of the following: determining whether to initiate random access triggered by the first service according to the configuration of at least one of the primary cell DTX and DRX of the terminal; determining whether to initiate random access triggered by the first service according to the configuration of at least one of the DTX and DRX of each service cell of the terminal; determining whether to initiate random access triggered by the first service according to the configuration of at least one of the DTX and DRX of each service cell in the main cell group MCG of the terminal.

[0027] Based on the above solution, the aforementioned first cell can be a primary cell, all service cells of the terminal, or one or more service cells in the MCG. In this way, it can be flexibly selected as needed when determining whether to initiate random access later.

[0028] In some embodiments of the first aspect, whether to initiate random access triggered by the first service is determined based on the configuration of at least one of DTX and DRX of the main cell of the terminal, including at least one of the following: when DTX and DRX are not configured in the main cell, determining not to initiate random access triggered by the first service; when at least one of DTX and DRX is configured in the main cell, determining whether to initiate random access triggered by the first service based on the activation status of at least one of DTX and DRX of the main cell.

[0029] Based on the above solution, if both DRX and DTX are not configured in the primary cell, the primary cell can provide communication services to the terminal at any time. Therefore, if the terminal has a first service to transmit, it can directly transmit the first service in the primary cell without initiating random access triggered by the first service. If at least one of DRX and DTX is configured in the primary cell, whether to initiate random access corresponding to the first service is further determined based on the activation status of DTX and / or DRX configured in the primary cell.

[0030] In some embodiments of the first aspect, when at least one of DTX and DRX is configured in the main cell, whether to initiate random access triggered by the first service is determined according to the activation status of at least one of DTX and DRX of the main cell, including: when at least one of DTX and DRX is configured in the main cell and at least one of DTX and DRX of the main cell is activated, whether to initiate random access triggered by the first service is determined according to whether the current moment is in the inactive period of DTX and / or DTX of the main cell; when at least one of DTX and DRX is configured in the main cell and DTX and DRX of the main cell are not activated, determining not to initiate random access triggered by the first service.

[0031] Based on the above scheme, when at least one of the DRX and DRX of the main cell is activated, it will be further determined whether to initiate random access triggered by the first service based on whether the current time period is in the inactive period of DTX and / or DRX activated by the main cell, thereby further reducing unnecessary random access of the terminal.

[0032] In some embodiments of the first aspect, at least one of DTX and DRX is configured in the primary cell and at least one of DTX and DRX is activated, and whether to initiate random access triggered by the first service is determined according to whether the current moment is in the inactive period of DTX and / or DTX in the primary cell, including at least one of the following: determining to initiate random access triggered by the first service when at least one of DTX and DRX is configured in the primary cell, at least one of DTX and DRX is activated, and the current moment is in the inactive period of DTX and / or DRX in the primary cell; determining not to initiate random access triggered by the first service when at least one of DTX and DRX is configured in the primary cell, at least one of DTX and DRX is activated, and the current moment is in the active period of DTX and / or DRX in the primary cell.

[0033] Based on the above solution, if the terminal is currently in the inactive period of DTX and / or DRX in the primary cell, it means that the terminal cannot communicate on the primary cell. Therefore, at this time, random access can be initiated so that the primary cell can provide the terminal with communication services related to the first business.

[0034] In some embodiments of the first aspect, whether to initiate random access triggered by the first service is determined based on the configuration of at least one of DTX and DRX of each service cell of the terminal, including at least one of the following: when there is a service cell of the terminal that is not configured with DTX and DRX, determining not to initiate random access triggered by the first service; when each service cell of the terminal is configured with at least one of DTX and DRX and there is at least one service cell DTX and DRX that are not activated in each service cell of the terminal, determining not to initiate random access triggered by the first service; when each service cell of the terminal is configured with at least one of DTX and DRX and at least one of DTX and DRX of each service cell of the terminal are activated, determining to initiate random access triggered by the first service based on whether at least one service cell DTX and / or DRX is in an activation period at the current moment.

[0035] Based on the above scheme, when at least one service cell of the terminal is not configured with DRX and DTX at the same time, the cell can be used to provide communication services of the first service to the terminal. Therefore, the terminal can perform the transmission of the first service on the cell that is not configured with DRX and DTX at the same time, and the terminal does not need to perform random access triggered by the first service.

[0036] In some embodiments of the first aspect, when there is a serving cell in the terminal that is not configured with DTX and DRX, it is determined not to initiate random access triggered by the first service, including: when there is a secondary cell in the terminal that is not configured with DTX and DRX, the secondary cell that is not configured with DTX and DRX is in an activated state and the activated bandwidth part BWP is not a dormant BWP, it is determined not to initiate random access triggered by the first service.

[0037] Based on the above scheme, if the serving cell for which the terminal is not configured with both DTX and DRX is the serving cell, it is also necessary to determine whether the serving cell is in an activated state. If the secondary cell is in an activated state and the activated BWP used is not a dormant BWP, it means that the secondary cell has a very high probability of providing the terminal with communication services related to the transmission of the first service. In this way, the terminal does not need to initiate random access triggered by the first service, thereby reducing unnecessary random access.

[0038] In some embodiments of the first aspect, when each service cell of the terminal is configured with at least one of DTX and DRX, and when at least one of DTX and DRX of each service cell of the terminal is activated, it is determined to initiate random access triggered by the first service according to whether it is the activation period of DTX and / or DRX of at least one service cell at the current moment, including at least one of the following: when each service cell of the terminal is configured with at least one of DTX and DRX, and when at least one of DTX and DRX of each service cell of the terminal is activated and the current moment is the activation period of DTX and / or DRX of at least one service cell, it is determined not to initiate random access triggered by the first service; when each service cell of the terminal is configured with at least one of DTX and DRX, and when at least one of DTX and DRX of each service cell of the terminal is activated and the current moment is not the inactivation period of DTX and / or DRX of any service cell, it is determined to initiate random access triggered by the first service.

[0039] Based on the above solution, the terminal will also determine whether it needs to initiate random access triggered by the first service according to whether the current moment is in the DTX and / or DRX activation period of each serving cell.

[0040] In some embodiments of the first aspect, whether to initiate random access triggered by the first service is determined based on the configuration of at least one of DTX and DRX of each service cell in the main cell group MCG of the terminal, including at least one of the following: when there is a service cell in the terminal MCG that is not configured with DTX and DRX, determining not to initiate random access triggered by the first service; when each service cell in the terminal MCG is configured with at least one of DTX and DRX, determining whether to initiate random access triggered by the first service is determined based on the activation status of at least one of DTX and DRX of each service cell in the MCG.

[0041] Based on the above solution, whether to initiate random access triggered by the first service is determined according to the DTX and DRX configuration of each serving cell in the MCG, which can also reduce unnecessary random access.

[0042] In some embodiments of the first aspect, when there is a service cell in the terminal MCG that is not configured with DTX and DRX, it is determined not to initiate random access triggered by the first service, including: when there is a secondary cell in the terminal MCG that is not configured with DTX and DRX, the secondary cell that is not configured with DTX and DRX is in an activated state and the activated bandwidth part BWP is not a dormant BWP, it is determined not to initiate random access triggered by the first service.

[0043] In some embodiments of the first aspect, when each service cell of the terminal MCG is configured with at least one of DTX and DRX, it is determined whether to initiate random access triggered by the first service according to the activation status of at least one of DTX and DRX of each service cell in the MCG, including at least one of the following: when each service cell of the terminal MCG is configured with at least one of DTX and DRX and at least one service cell DTX and DRX in the MCG is not activated, it is determined not to initiate random access triggered by the first service; when each service cell of the terminal MCG is configured with at least one of DTX and DRX and at least one service cell DTX and DRX in the MCG is activated, it is determined whether to initiate random access triggered by the first service according to whether the current moment is in the activation period of DTX and / or DRX of each service cell in the MCG.

[0044] Based on the above solution, when the current moment is not the DTX and / or DRX activation period of any serving cell in any MCG, it is determined whether to initiate random access triggered by the first service, which can further reduce unnecessary random access.

[0045] In some embodiments of the first aspect, when each service cell of the terminal MCG is configured with at least one of DTX and DRX and at least one of DTX and DRX of each service cell in the MCG is activated, whether to initiate random access triggered by the first service is determined according to whether the current moment is in the activation period of DTX and / or DRX of each service cell in the MCG, including at least one of the following: when each service cell of the terminal MCG is configured with at least one of DTX and DRX, at least one of DTX and DRX of each service cell in the MCG is activated and the current moment is in the activation period of DTX and / or DRX of at least one service cell in the MCG, determining not to initiate random access triggered by the first service; when each service cell of the terminal MCG is configured with at least one of DTX and DRX, at least one of DTX and DRX of each service cell in the MCG is activated and the current moment is in the non-activation period of DTX and / or DRX of each service cell in the MCG, determining to initiate random access triggered by the first service.

[0046] In some embodiments of the first aspect, the first service includes an emergency call service.

[0047] According to a second aspect, a terminal is provided, comprising: a processing module configured to determine whether to initiate random access triggered by a first service based on a configuration of at least one of discontinuous transmission (DTX) and discontinuous reception (DRX) of at least one serving cell of the terminal.

[0085] In view of this, as shown in FIG2 , an embodiment of the present disclosure provides a random access initiation method, which is executed by a communication system. The method may include:

[0086] S2101: The terminal determines whether to initiate random access triggered by a first service.

[0087] In some embodiments, the first service may be any designated service.

[0088] In some embodiments, the first service may be any service whose delay tolerance is less than a specified value.

[0089] In some embodiments, the first service includes at least an emergency call service.

[0090] In some embodiments, the first service may be a service in which the terminal acts as a calling terminal to make an emergency call to another terminal.

[0091] In some embodiments, the random access may include: four-step random access and / or two-step random access.

[0092] In some embodiments, the random access may be contention-based random access and / or non-contention-based random access.

[0093] In some embodiments, whether to initiate random access triggered by the first service is determined according to a configuration of at least one of discontinuous transmission (DTX) and discontinuous reception (DRX) of at least one serving cell of the terminal.

[0094] In some embodiments, the configuration status may indicate whether at least one serving cell of the terminal is configured with DTX and / or DRX.

[0095] In some embodiments, if a serving cell is configured with DTX and DTX is activated, the serving cell performs downlink transmission during the DTX activation period and does not perform downlink transmission during the DTX inactive period. When not performing downlink transmission during the DTX inactive period, the serving cell may enter a low power consumption state to save energy.

[0096] For example, as shown in FIG1B , the DTX cycle corresponding to the cell DTX may include an active period and a non-active period.

[0097] In some embodiments, if DRX is activated for a serving cell, the serving cell performs uplink reception during the DRX activation period and does not perform uplink reception during the DRX inactive period. When not performing uplink reception during the DRX inactive period, the serving cell may enter a low power consumption state to save energy.

[0098] For example, as shown in FIG1C , the DRX cycle corresponding to the cell DRX may include an active period and a non-active period.

[0099] In some embodiments, the terminal supports carrier aggregation, dual connectivity, or multi-connectivity. In this case, the terminal may have multiple serving cells. These serving cells may include: a primary cell and a secondary cell.

[0100] In some embodiments, the secondary cells may include: primary secondary cells and common secondary cells.

[0101] In some embodiments, the aforementioned at least one serving cell may include: a primary cell, a primary secondary cell and / or a common secondary cell.

[0102] In some embodiments, S2101: when at least one serving cell of the terminal is not configured with DTX and DRX, determine not to initiate random access triggered by the first service.

[0103] If at least one of the service cells of the terminal is not configured with at least one of DTX and DRX, when the terminal has a first service to be transmitted, the transmission of the first service can be performed directly on at least one of the service cells that are not configured with DTX and DRX, thereby reducing unnecessary random access initiated by the terminal and reducing power consumption generated by other cells configured with DRX and DRX due to receiving random access of the terminal.

[0104] In some embodiments, S2101: when at least one serving cell of the terminal is configured with at least one of DTX and DRX, determine whether to initiate random access triggered by the first service according to the activation status of at least one of DTX and DRX configured in at least one serving cell of the terminal.

[0105] In some embodiments, the activation status may indicate whether DTX and / or DRX of at least one serving cell of the terminal is activated.

[0106] In some embodiments, S2101 may include:

[0107] Whether to initiate random access triggered by the first service is determined according to a configuration of at least one of DTX and DRX of a primary cell of the terminal; the primary cell is one of the serving cells of the terminal.

[0108] In some embodiments, when DTX and DRX are not configured in the primary cell, it is determined not to initiate random access triggered by the first service.

[0109] Since the main cell of the terminal is not configured with DTX and / or DRX, it is equivalent to that the main cell can always provide services to the terminal. When the terminal has transmission related to the first service, it does not need to transmit the first service through random access. On the one hand, it can reduce unnecessary random access of the terminal, and on the other hand, it can also reduce the first service transmission delay introduced by unnecessary random access of the terminal.

[0110] In some embodiments, when at least one of DTX and DRX is configured in the primary cell, whether to initiate random access triggered by the first service is determined according to an activation status of at least one of DTX and DRX of the primary cell.

[0111] The activation status of the primary cell's DTX and DRX can reflect whether the primary cell's DTX and DRX are activated. If the primary cell's DTX and DRX are activated, the primary cell may not perform downlink transmission and / or uplink reception during periods of DTX and / or DRX inactivity, which may hinder the terminal's first service transmission. In this case, the determination of whether to initiate random access triggered by the first service is based on the activation status of the primary cell's DTX and / or DRX to maximize cell space savings and / or meet the latency requirements for the first service transmission.

[0112] In some embodiments, if at least one of DTX and DRX is configured in the main cell and at least one of DTX and DRX of the main cell is activated, it can be determined that random access triggered by the first service is initiated regardless of whether the current time period is in the inactive period of DTX and / or DTX of the main cell.

[0113] In some embodiments, at least one of DTX and DRX is configured in the main cell and at least one of DTX and DRX of the main cell is activated. Whether to initiate random access triggered by the first service is determined based on whether the current moment is in the inactive period of DTX and / or DTX of the main cell.

[0114] Further, in the primary cell, at least one of DTX and DRX is configured, at least one of DTX and DRX of the primary cell is activated, and the current moment is in an inactive period of DTX and / or DRX of the primary cell, determining to initiate random access triggered by the first service;

[0115] When at least one of DTX and DRX is configured in the primary cell, at least one of DTX and DRX in the primary cell is activated, and the current moment is in the activation period of DTX and / or DRX in the primary cell, it is determined not to initiate random access triggered by the first service.

[0116] In some embodiments, the current moment can be understood as the moment when the first service is determined to be transmitted.

[0117] In some embodiments, the current time may be the time when the first service initiated by the upper layer is received.

[0118] In some embodiments, the current time may be the time when the emergency service initiated by the upper layer is received.

[0119] In some embodiments, the MAC layer of the terminal receives a signal from an upper layer initiating a first service. In some embodiments, the upper layer may include but is not limited to an application layer and / or a non-access layer.

[0120] If the current moment is in the inactive period of DTX and / or DRX in the primary cell, it may take some time for the primary cell to enter the active period of DTX and / or DRX. At this time, in order to meet the delay requirement of the first service, it is determined to initiate random access. In this way, after receiving the random access of the terminal, the cell can meet the delay requirement of the terminal's first service transmission by exiting the cell's DTX and / or DRX. Alternatively, after receiving the random access, the cell can configure communication resources that meet the terminal's first service transmission without exiting the cell's DTX and / or DRX to meet the delay requirement of the terminal's first service transmission.

[0121] If the current moment is in the activation period of DTX and / or DRX of the primary cell, the terminal can transmit the first service in the activation period, and there is no need to initiate random access, thereby reducing unnecessary random access and reducing the delay introduced by random access.

[0122] In some embodiments, S2101 may include: determining whether to initiate random access triggered by the first service according to a configuration of at least one of DTX and DRX of each serving cell of the terminal.

[0123] In some embodiments, if the terminal supports carrier aggregation and / or dual connectivity, the terminal may have multiple serving cells.

[0124] In some embodiments, when there is a serving cell of the terminal that is not configured with DTX and DRX, it is determined not to initiate random access triggered by the first service.

[0125] In some embodiments, when at least one of the serving cells for which the terminal is not configured with DTX and DRX is a secondary cell, and the secondary cell is activated and performs non-dormancy behavior, it means that the secondary cell is available for the terminal to perform the transmission of the first service, and it is determined that the terminal does not initiate random access triggered by the first service.

[0126] A secondary cell can be activated or deactivated. If a secondary cell is deactivated, it means that the secondary cell is not activated and does not send or receive data from the terminal. Therefore, after ensuring that the secondary cell that is not configured with DTX and / or DRX is activated and not in sleep mode, the random access triggered by the first service is determined.

[0127] In some embodiments, the cell performing non-dormancy behavior means that the active BWP of the terminal is not a dormancy BWP. If the active BWP of the secondary cell is a dormancy BWP, the dormancy BWP is a BWP in a dormancy state, which may not be used for data transmission.

[0128] In this case, if the terminal has at least one serving cell that is not configured with DTX and / or DRX, the terminal does not need to initiate random access triggered by the first service, but directly performs the transmission of the first service on the serving cell that is not configured with DTX and / or DRX.

[0129] When at least one of DTX and DRX is configured in each serving cell of the terminal and DTX and DRX are not activated in at least one serving cell among the serving cells of the terminal, it is determined not to initiate random access triggered by the first service.

[0130] In some embodiments, if each service cell of the terminal is configured with DTXD and / or DRX, it is determined whether the terminal has at least one service cell in which DTX and / or DRX are not activated. If there is a service cell in which DTX and / or DRX are not activated, the terminal can use the cell in which DTX and / or DRX are not activated to transmit the first service, and there is no need to initiate random access triggered by the first service.

[0131] In some embodiments, when at least one of DTX and DRX is configured in each serving cell of the terminal and at least one of DTX and DRX is activated in each serving cell of the terminal, it is determined to initiate random access triggered by the first service.

[0132] In this case, since DTX and / or DRX of each serving cell of the terminal are activated, for the sake of simplicity, it can be determined that the terminal initiates random access triggered by the first service.

[0133] In some embodiments, when each service cell of the terminal is configured with at least one of DTX and DRX and at least one of DTX and DRX of each service cell of the terminal is activated, the random access triggered by the first service is determined based on whether at least one service cell DTX and / or DRX is activated at the current moment.

[0134] The relevant description of the current moment here can be found in the aforementioned embodiment and will not be repeated here.

[0135] In one embodiment, when each service cell of the terminal is configured with at least one of DTX and DRX, when at least one of DTX and DRX of each service cell of the terminal is activated and the current moment is the activation period of DTX and / or DRX of at least one service cell, it is determined not to initiate random access triggered by the first service.

[0136] At the current moment, it is the DTX and / or DRX activation period of at least one serving cell, then the terminal can perform transmission of the first service on the cell in the DTX and / or DRX activation period without initiating random access triggered by the first service.

[0137] In some embodiments, when at least one of DTX and DRX is configured in each service cell of the terminal, and at least one of DTX and DRX in each service cell of the terminal is activated and the current moment is not the inactive period of DTX and / or DRX of any service cell, it is determined to initiate random access triggered by the first service.

[0138] When the current moment is not in the activation period of DTX and / or DRX of any service cell, random access is initiated to make at least one service cell exit DTX and / or DRX, or resources for transmitting the first service are configured for the terminal to meet the transmission requirements of the first service.

[0139] In some embodiments, S2101 may include: when a serving cell of the terminal MCG has no DTX and DRX configured, determining not to initiate random access triggered by the first service.

[0140] In some embodiments, the MCG is the cell group where the primary cell of the terminal is located. In this case, there is no need to pay attention to the secondary cell group of the terminal.

[0141] If there is at least one serving cell in the MCG that is not configured with cell DTX and / or cell DRX, the terminal can perform transmission of the first service in the cell, and there is no need to initiate random access triggered by the first service.

[0142] In some embodiments, the MCG includes a primary cell and a secondary cell. If at least one of the cells that is not configured with DTX and DRX is a secondary cell, when the secondary cell is activated and performs non-dormancy behavior, it means that the secondary cell can be used by the terminal to perform the transmission of the first service, and it is determined that the terminal does not initiate random access triggered by the first service.

[0143] In some embodiments, the cell performing the non-dormancy behavior means that the active BWP of the terminal is not a dormancy BWP.

[0144] In some embodiments, S2101 may include: when each service cell of the terminal MCG is configured with at least one of DTX and DRX, determining whether to initiate random access triggered by the first service according to the activation status of at least one of DTX and DRX in each service cell in the MCG.

[0145] When each service cell in the MCG is configured with DTX and DRX, it is necessary to determine whether it is necessary to initiate random access triggered by the first service based on the activation status of DTX and / or DRX of each service cell in the MCG. This can reduce the inconvenience of random access required by the terminal while ensuring the timely transmission of the first service.

[0146] In some embodiments, when each service cell in the MCG is configured with DTX and DRX, and at least one of the DTX and DRX of at least one service cell in the MCG is not activated, it can be determined that random access triggered by the first service is not initiated.

[0147] In some embodiments, when each serving cell in the MCG is configured with DTX and DRX, at least one of the DTX and DRX of at least one serving cell in the MCG is activated, and it can be determined that a random access triggered by the first service is initiated.

[0148] In some embodiments, when each serving cell in an MCG is configured with DTX and DRX, at least one of the DTX and DRX of at least one serving cell in the MCG is activated, and whether to initiate random access triggered by the first service is determined based on whether the current time period is within the activation period of DTX and / or DRX of each serving cell in the MCG. In this embodiment, unnecessary random access initiated by the terminal can be further reduced.

[0149] In some embodiments, when each serving cell of the terminal MCG is configured with at least one of DTX and DRX, at least one of DTX and DRX of each serving cell in the MCG is activated, and the current moment is in the activation period of DTX and / or DRX of at least one serving cell in the MCG, it is determined not to initiate random access triggered by the first service;

[0150] In the terminal MCG, each service cell is configured with at least one of DTX and DRX, at least one of DTX and DRX of each service cell in the MCG is activated, and the current moment is in the non-activation period of DTX and / or DRX of each service cell in the MCG, and it is determined to initiate random access triggered by the first service.

[0151] In some embodiments, MCG may also be replaced by a designated cell group. The designated cell group may be a cell group including primary and secondary cells. That is, according to whether each service cell in the designated cell group is configured with at least one of DTX and DRX, it is determined whether to initiate random access triggered by the first service. According to the fact that each service cell in the designated cell group is not configured with at least one of DTX and DRX, it is determined not to initiate random access triggered by the first service. According to the fact that each service cell in the designated cell group is configured with at least one of DTX and DRX, according to the activation status of DTX and / or DRX of each service cell in the designated cell group and / or whether the current time period is in the activation time period of DTX and / or DRX of each service cell in the designated cell group, it is determined not to initiate random access triggered by the first service.

[0152] S2102: The terminal initiates random access.

[0153] In some embodiments, when it is determined to initiate random access, random access is initiated.

[0154] In some embodiments, the terminal initiates random access on a primary cell, a primary secondary cell, or other common secondary cells.

[0155] As shown in FIG3 , an embodiment of the present disclosure provides a random access initiation method, which is executed by a terminal. The method includes:

[0156] S3101: Determine whether to initiate random access triggered by a first service.

[0157] In some embodiments, the optional embodiments of S3101 can refer to S2101 of the corresponding embodiment of Figure 2, which will not be repeated here.

[0158] S3102: Initiate random access.

[0159] In some embodiments, the optional embodiments of S3102 can refer to S2102 of the corresponding embodiment of Figure 2, which will not be repeated here.

[0160] It is worth noting that S3102 is an optional step. For example, when it is determined in S3101 that random access triggered by the first service is not to be initiated, there is no need to execute S3102.

[0161] In the Carrier Aggregation (CA) scenario or the Multi-(Radio Access technology, RAT) Dual Connectivity, MR-DC) scenario, if there is a serving cell that is not configured with cell DTX / DRX (DTX / DRX for short), or the configured cell DTX / DRX is not activated, the emergency call service can be carried out normally. In particular, if the primary cell (pcell) is not activated or the cell DTX / DRX is not configured, there is no need to perform the Random Access Channel (RACH) RACH process to meet the emergency call service.

[0162] Here, the RACH process is the random access process of the terminal. The following RACH process provides several ways to reduce unnecessary random access by the terminal, and proposes one or more of the following methods:

[0163] Method 1:

[0164] If the cell DTX and / or cell DRX of the PCell is in an activated state, and / or the current period is in a non-active period of the primary cell DTX and / or DRX, if the terminal initiates an emergency call service at this time, the terminal initiates the RACH process; otherwise, the RACH process does not need to be initiated for the emergency call.

[0165] Method 2:

[0166] Option 1: If there is no serving cell that meets both of the following conditions, initiate a RACH procedure. Otherwise, do not initiate a RACH procedure for the emergency call.

[0167] Condition 1: The Scell ​​is in the activated state and non-dormancy; if the secondary cell is non-dormancy, it means that the secondary cell has no dormancy behavior, that is, the activated BWP of the secondary cell is not a dormant BWP.

[0168] Condition 2: cell DTX and / or cell DRX is in the deactivated state, or cell DTX and / or cell DRX is not configured.

[0169] Option 2: If there is no serving cell on the MCG side that meets all of the following conditions, initiate a RACH procedure. Otherwise, do not initiate a RACH procedure for the emergency call:

[0170] Condition 1: The Scell ​​is in the activated state and non-dormancy. The non-dormancy of the secondary cell means that the activated BWP of the secondary cell is not a dormant BWP.

[0171] Condition 2: cell DTX and / or cell DRX is in the deactivated state, or cell DTX and / or cell DRX is not configured.

[0172] If the terminal initiates an emergency call service at this time, the terminal initiates the RACH process, otherwise there is no need to initiate the RACH process for the emergency call.

[0173] In summary, based on the cell DTX / DRX configuration state or activation state of the PCell, it is determined whether a RACH process is initiated for an emergency call. For example, for the PCell, if both cell DTX (DTX for short) and cell DRX (DRX for short) are not configured, or if cell DTX and / or DRX are configured but not activated, the RACH process is not triggered. Otherwise, the RACH process is triggered.

[0174] Based on the cell DTX / DRX configuration status or activation status of all serving cells, a comprehensive judgment is made as to whether to initiate a RACH process for an emergency call service. For example, if there is a serving cell that is not configured with both cell DTX and DRX, or if the configured DTX and / or DRX are not activated, and if the cell is a secondary cell and the secondary cell is in an activated state and not dormant, then the RACH process may not be triggered; otherwise, the RACH process is triggered.

[0175] In the embodiments of the present disclosure, some or all of the steps and their optional implementations may be arbitrarily combined with some or all of the steps in other embodiments, or may be arbitrarily combined with the optional implementations of other embodiments.

[0176] In the embodiments of the present disclosure, some or all of the steps and their optional implementations may be arbitrarily combined with some or all of the steps in other embodiments, or may be arbitrarily combined with the optional implementations of other embodiments.

[0177] The embodiments of the present disclosure also provide an apparatus for implementing any of the above methods. For example, an apparatus is provided, comprising units or modules for implementing each step performed by a terminal in any of the above methods. For another example, another apparatus is provided, comprising units or modules for implementing each step performed by a network device (e.g., an access network device or a core network device) in any of the above methods.

In actual implementation, they may be fully or partially integrated into a physical entity, or they may be physically separated. In addition, the units or modules in the device may be implemented in the form of a processor calling software: for example, the device includes a processor, the processor is connected to a memory, and the memory stores instructions.

All units or modules of the above devices can be realized in the form of software called by the processor, or in the form of hardware circuits, or in part by the form of software called by the processor, and the rest by hardware circuits.

In one implementation, the processor can be a circuit with instruction reading and execution capabilities, such as a central processing unit (CPU), a microprocessor, a graphics processing unit (GPU) (which can be understood as a microprocessor), or a digital signal processor (DSP). In another implementation, the processor can implement certain functions through the logical relationship of a hardware circuit. The logical relationship of the above-mentioned hardware circuit is fixed or reconfigurable. For example, the processor is a hardware circuit implemented by an application-specific integrated circuit (ASIC) or a programmable logic device (PLD), such as an FPGA. In a reconfigurable hardware circuit, the process of the processor loading a configuration document to implement the hardware circuit configuration can be understood as the process of the processor loading instructions to implement the functions of some or all of the above units or modules. In addition, it can also be a hardware circuit designed for artificial intelligence, which can be understood as an ASIC, such as a neural network processing unit (NPU), a tensor processing unit (TPU), a deep learning processing unit (DPU), etc.

[0180] As shown in FIG4 , an embodiment of the present disclosure provides a terminal, wherein the terminal includes:
