Please refer to Figure 2, which is a flow chart of an uplink processing method provided by an embodiment of the present disclosure. As shown in Figure 2, the uplink processing method includes the following steps:

Step 201: The terminal obtains first information, which is used to indicate that the first downlink service reaches the network device;

Step 202: The terminal triggers execution of an uplink transmission process in a non-connected state according to the first information.

The existence of the first downlink traffic arriving at the network device can be understood as the existence of the first downlink traffic about to reach the network device. The first downlink service can be understood as the downlink service that needs to be received by the terminal. The first downlink service can be a periodic service or an event service.

The non-connected state may include Radio Resource Control (RRC) inactive state (RRC_INACTIVE) and RRC idle state (RRC_IDLE).

The network device may be a RAN side device. In the 5G system, the RAN may be called NG-RAN (ie, 5G radio access network). The RAN involved in this disclosure may include NG-RAN. The existence of the first downlink (Down Link, DL) service reaching the network device can be understood as the existence of the first downlink service reaching the RAN side device. The network device can also be a core network device, such as Access and Mobility Management Function (AMF) and/or User Port Function (UPF). The first downlink service arriving at the network device can be understood If there is a first downlink service, it reaches the AMF and/or UPF. For example, for an idle terminal, if the first downlink service is downlink signaling, the first downlink service may arrive at the AMF first; if the first downlink service is downlink data, the first downlink service may arrive at the UPF first.

The terminal triggers the execution of the Up Link (UL) transmission process in the non-connected state. It can be understood that the terminal can actively trigger the execution of the connection with the network device in the non-connected state. As an example, the terminal can trigger the connection with the network device in the access layer (Access Stratum, AS). ) actively triggers the execution of the uplink transmission process.

The disclosed embodiments can be applied to the following scenario: the first downlink service that needs to be received by the terminal is about to reach the network device, and the terminal is in a non-connected state at this time. In this scenario, if the terminal knows that the first downlink service will arrive at the network device, the terminal can actively trigger the connection with the network device based on the characteristic information of the first downlink service. That is, the terminal can actively trigger the execution in the non-connected state. Uplink transmission process. In this way, when the first downlink service reaches the network device, the network device can send the first downlink service to the terminal without triggering the paging process. This can save signaling overhead, reduce the power consumption of the terminal and the network device, and Reduce latency. For example, when the terminal is an inactive terminal, the terminal can establish a connection with the RAN-side device after triggering the uplink transmission process without requiring the RAN-side device to trigger the uplink transmission process. Send and execute the paging process. For another example, when the terminal is an idle terminal, the terminal can establish a connection with the AMF after triggering the uplink transmission process, without the need for the AMF to trigger the Core Network paging (CN paging) process.

In some embodiments, the terminal obtains the first information before the first downlink service reaches the network device. That is to say, the terminal can obtain the first information in advance before the first downlink service reaches the network device, thereby enabling the terminal to trigger the execution of the uplink transmission process at an appropriate time, which is beneficial to improving service processing efficiency.

In some embodiments, the terminal obtains the first information, including one or more of the following:

The terminal receives a first message sent by the network device, where the first message contains the first information;

The terminal obtains the first information based on a preset algorithm;

The terminal obtains the first information based on the interaction between the terminal and the higher layer.

As an example, the network device may learn from a higher layer (such as an application layer or a core network) or based on its own algorithm that there is a first downlink service arriving at the network device. On this basis, the network device can notify the terminal receiving the first downlink service in advance through the first message. The first message may be an RRC message or a message from other layers. For example, the first message may be an RRC release message (RRCRelease message). As another example, the terminal may know that there is a first downlink service that needs to be received to reach the network device based on its own algorithm or inter-layer interaction with a higher layer.

In some embodiments, the uplink transmission process includes one or more of the following:

RRC connection process;

RRC connection recovery process;

Small Data Transmission (SDT) process.

The RRC connection process may correspond to the idle state terminal, that is, when the terminal is in the idle state, the uplink transmission process triggered by the terminal may be the RRC connection process. For example, the terminal sends traditional Send the RRCConnectionRequest message to the network device and wait for the RRC message reply from the network device.

The RRC connection recovery process may correspond to the inactive state terminal, that is, when the terminal is in the inactive state, the uplink transmission process triggered by the terminal may be the RRC connection recovery process. The RRC connection recovery process can also be called the process of resuming a suspended RRC connection. For example, the terminal sends a traditional RRCResumeRequest message to the network device and waits for the RRC message reply from the network device.

The SDT process may correspond to the inactive state terminal, that is, when the terminal is in the inactive state, the uplink transmission process triggered by the terminal may be the SDT process. SDT technology has been introduced in version 17 (Release 17, R17) NR. When the terminal is in the inactive state, the terminal can directly send and/or receive small data, that is, the inactive terminal can remain in the inactive state to send and/or receive small data, which can prevent the terminal from frequently entering the connected state and help reduce signaling overhead. On this basis, in the embodiments of the present disclosure, when the terminal is in an inactive state, the terminal can actively trigger the execution of the SDT process based on the characteristic information of the first downlink service. As an example, if the terminal has no uplink data to be sent at this time, the terminal can trigger the execution of the SDT process; or, if the terminal has only small data packets to be sent on the uplink at this time, which complies with the SDT sending rules, the terminal can trigger the execution of the SDT process.

In some embodiments, the terminal triggers the execution of an uplink transmission process (specifically, triggers the execution of an SDT process) in the non-connected state based on the first information, including at least one of the following:

When the network device is pre-configured with first configuration information, the terminal triggers execution of the SDT process in a non-connected state based on the first information, and the first configuration information is used to indicate that the terminal is The SDT process is allowed to be used when the downlink service reaches the network device and the uplink transmission process is actively triggered;

When the terminal meets the preset SDT condition, the terminal triggers execution of the SDT process in the non-connected state according to the first information, and the preset SDT condition is the SDT condition predefined by the protocol.

In the case where the network side device does not pre-configure the first configuration information, the terminal may perform an RRC connection process or an RRC connection recovery process. Alternatively, if the terminal does not meet the preset SDT conditions, the terminal may perform an RRC connection process or an RRC connection recovery process.

It should be noted that the SDT technology introduced in R17 is aimed at uplink small data originated from inactive terminals. Embodiments of the present disclosure can be applied to the SDT process of small data downlink services initiated by network equipment in the inactive state (that is, the first downlink service is small data downlink services initiated by network equipment). The terminal can Based on the characteristic information of small data downlink services originated from network equipment, the uplink transmission process is actively triggered to reduce signaling overhead and even delay.

In some embodiments, the first information includes one or more of the following:

The time information when the first downlink service reaches the network device;

Transmission resource information corresponding to the first downlink service.

The first information can also be understood as characteristic information of the first downlink service, which may include at least one of time information for the first downlink service to arrive at the network device and transmission resource information corresponding to the first downlink service.

In some embodiments, the time information includes: one or more of period information of the first downlink service arriving at the network device and time information of the first downlink service arriving at the network device;

The transmission resource information includes one or more of a Radio Bearer identity (RB ID) and a Logical channel identity (LCID).

In some embodiments, the first downlink service is a periodic service;

The terminal triggers execution of an uplink transmission process in a non-connected state based on the first information, including:

The terminal periodically triggers the execution of an uplink transmission process in a non-connected state according to the cycle information of the first downlink service arriving at the network device.

For the periodic first downlink service, the terminal can obtain the period information of the arrival of the first downlink service at the network device. For example, the network device obtains the cycle information of the first downlink service arriving at the network device from a higher layer or based on its own algorithm, and the network device notifies the terminal receiving the downlink service in advance through a message. Or, based on its own algorithm or inter-layer interaction, the terminal knows the periodic information on which the first downlink service that needs to be received reaches the network device. On this basis, the terminal can periodically actively trigger the execution of the uplink transmission process according to the periodic information of the first downlink service arriving at the network device.

Additionally, for the periodic first downlink service, the terminal can also obtain the time t1 when the first downlink service arrives at the network device and the interval period (cycle1) at which the first downlink service arrives at the network device. On this basis, the terminal can periodically actively trigger the execution of the uplink transmission process in the non-connected state starting from time t1 with cycle1 as the interval.

It should be noted that for the situation where the terminal periodically triggers the execution of the uplink transmission process, each time the terminal actively triggers the execution of the uplink transmission process, it can be determined whether the terminal is currently in a non-connected state, such as If so, the uplink transmission process is actively triggered; if the terminal is already in the connected state, there is no need to actively trigger the uplink transmission process.

In some embodiments, the period information includes the starting time when the first downlink service arrives at the network device and the interval period at which the first downlink service arrives at the network device; wherein, the starting time The starting moment includes one or more of the following:

The moment corresponding to the terminal receiving the first message sent by the network device, where the first message contains the first information;

Starting from the moment when the terminal receives the first message, the corresponding moment is delayed by N intervals after the interval period, where N is an integer greater than or equal to 1;

The moment corresponding to the terminal receiving the second message sent by the network device, the second message containing an uplink indication, and the uplink indication being used to instruct the terminal to trigger execution of the uplink transmission process;

Starting from the moment when the terminal receives the second message, the corresponding moment is delayed M times after the interval period, where M is an integer greater than or equal to 1;

Starting from the moment when the terminal triggers the execution of the uplink transmission process for the first time, the corresponding moment is delayed by S intervals, where S is an integer greater than or equal to 1.

In this embodiment, the terminal may determine the time at which the first downlink service subsequently arrives at the network device based on the starting time at which the first downlink service arrives at the network device and the interval period at which the first downlink service arrives at the network device.

As an example, the starting time may be the time when the terminal receives the first message from the network device, and the corresponding time is delayed by T1 (T1 is a cycle of the first downlink service); or the starting time is when the terminal receives the first message from the network device. The moment when the network device triggers the signaling or indication of "the non-connected terminal actively triggers the execution of the uplink transmission process" (the signaling or indication may be different from the first message); or, the starting time is when the terminal receives the trigger from the network device The starting time is the time when the signaling or instruction of "the non-connected terminal actively triggers the execution of the uplink transmission process" is delayed to the corresponding time after T1; or, the starting time is the time when the terminal triggers the SDT process because the network equipment initiates the downlink service. , delayed by the corresponding time after T1.

It should be noted that, in addition to the terminal actively triggering the execution of the uplink transmission process after acquiring the characteristic information of the first downlink service, the terminal may also implicitly consider the transmission process to be performed for other reasons (such as after the terminal originates or is paged by a network device). If the downlink service feature is activated, it will be in the non-connected state during the subsequent process. Periodically actively trigger the execution of the uplink transmission process.

In some embodiments, the first downlink service is an event service;

The terminal triggers execution of an uplink transmission process in a non-connected state according to the first information, which further includes:

The terminal triggers execution of the uplink transmission process in a non-connected state at the moment when the first downlink service reaches the network device.

For the event-based first downlink service, the terminal can obtain the time when the first downlink service arrives at the network device. For example, the network device obtains the time when the first downlink service reaches the network device from a higher layer or based on its own algorithm, and the network device notifies the terminal receiving the downlink service in advance through a message. Alternatively, the terminal knows the time when the first downlink service to be received reaches the network device based on its own algorithm or inter-layer interaction. The time here can be an absolute time or a relative time, such as the time relative to the current time of the cellular network. On this basis, the terminal can actively trigger the execution of the uplink transmission process at the moment when the first downlink service reaches the network device.

It should be noted that, regardless of whether the first downlink service is a periodic service or an event service, the disclosed embodiments are not only applicable to downlink small data transmission, but also to other downlink services, as long as the downlink service reaches certain specific characteristics.

In some embodiments, the terminal triggers the execution of an uplink transmission process in a non-connected state based on the first information, including:

The terminal performs a Unified Access Control (UAC) process in a non-connected state based on the first information;

Based on the UAC process, the terminal triggers execution of an uplink transmission process in a non-connected state.

In this embodiment, at the very beginning when the terminal actively triggers the execution of the uplink transmission process, the UAC process can be executed to determine whether the terminal is allowed to trigger the execution of the uplink transmission process. If the UAC result is that the terminal is allowed to trigger the execution of this process, the terminal can trigger the execution of the subsequent uplink transmission process. transmission process.

The Access Category (AC) on which the UAC process is based can be an existing access category or a new access category.

In some embodiments, the access category based on the UAC process includes any of the following:

The first access category is used to instruct the terminal to actively trigger the execution of the uplink transmission process;

The second access category is used to instruct the terminal to actively trigger the execution of the uplink transmission process because downlink traffic reaches the network device;

The third access category is used to instruct the mobile station to access when called. For example, the third access category is Mobile Terminated (MT);

The fourth access category is used to instruct the mobile station to access when it initiates a call. For example, the fourth access category is Mobile Originated signaling (Mobile Originated signaling, MO signaling).

The first access category and the second access category are new access categories, and the third access category and the fourth access category are existing access categories.

In some embodiments, the uplink processing method further includes:

The terminal sends a second message to the network device, where the second message includes at least one of the following indication information:

The first indication information is used to indicate that the reason why the terminal triggers the uplink transmission process is that the mobile station is called;

The second indication information is used to indicate that the reason why the terminal triggers the uplink transmission process is that the mobile station initiates the signal;

The third indication information is used to indicate that the reason why the terminal triggers the uplink transmission process is that the downlink service reaches the network device;

The fourth indication information is used to indicate the time information when the first downlink service reaches the network device.

In this embodiment, the terminal may inform the network device of the establishment reason or recovery reason that triggers the execution of the uplink transmission process (ie, the reason for restoring the RRC connection) through the second message. For example, the establishment reason or recovery reason that triggers the execution of the uplink transmission process may be MT or MO signaling, or for a new reason, such as for downlink traffic to reach the network device. Further, it can be for "periodic downlink traffic to reach the network device", or for "event downlink traffic to reach the network device". In addition, the fourth indication message may be sent by the terminal to the network device when the terminal obtains the time information of the arrival of the first downlink service at the network device based on a preset algorithm or based on inter-layer interaction.

For network equipment, after receiving the uplink message sent by the terminal, relevant responses can be made based on the uplink message and the arrival of the first downlink service, depending on the network implementation.

For example, the RAN side device can send a RRCResume message to the terminal based on the received uplink message and the received first downlink service to transfer the terminal to the connected state, and send the first downlink service to the terminal in the connected state. Or, the RAN side device receives the uplink message, but the first downlink service has not yet arrived. Then the RAN side device can first send a RRCResume message to the terminal to transfer the terminal to the connected state, and the RAN side device waits for the arrival of the first uplink service. Alternatively, after receiving the uplink message, the RAN side device can keep the terminal in a non-connected state and perform the transmission of relevant uplink messages and downlink messages in the SDT process.

In summary, through the above process, the terminal actively triggers the connection with the network device, avoiding the network device from triggering the paging process, saving signaling overhead, reducing the power consumption of the terminal and the network device, and reducing the delay.

The network device in the embodiment of the present disclosure may be a RAN side device or a core network device, such as an AMF.

It should be noted that this embodiment is an implementation of the network device corresponding to the embodiment shown in Figure 2. For its specific implementation, please refer to the relevant description of the embodiment shown in Figure 2. In order to avoid repeated explanation, this embodiment The embodiments will not be described again, and the same beneficial effects can also be achieved.

The following illustrates the uplink processing method provided by the embodiments of the present disclosure through multiple embodiments with reference to Figures 4 to 7:

Embodiment 1 (see Figure 4):

Step 41: The RAN side device obtains the period in which the first downlink service reaches the RAN side from the higher layer or based on its own algorithm.

Further, a radio bearer ID (RB ID) or a logical channel identity (Logical channel identity) corresponding to the first downlink service can be configured.

Step 42: The RAN side device notifies the terminal receiving the first downlink service in advance through a message.

The message may be an RRC message or a message from other layers; further, the message may be an RRCRelease message.

Step 43: The terminal periodically actively triggers the execution of the uplink transmission process at the periodic time when the first downlink service reaches the RAN side.

Furthermore, every time the terminal actively triggers the execution of the uplink transmission process, it needs to determine whether the terminal is currently in the RRC inactive state. If so, it actively triggers the execution of the uplink transmission process; if the terminal is already in the RRC connected state, it does not need to actively trigger the execution. Uplink transmission process.

Optionally, at the beginning of the terminal actively triggering the uplink transmission process, the terminal executes the UAC process to determine whether the terminal is allowed to trigger the uplink transmission process; during the UAC process, the access category can be a new access category, such as a new access category. The entry category means that the terminal actively triggers the execution of the uplink transmission process, or the terminal actively triggers the execution of the uplink transmission process because the downlink service reaches the RAN side. It can also use the existing access category, such as MT or MO signaling. If the UAC result is that the terminal is allowed to trigger this process, the terminal will trigger the subsequent uplink transmission process.

The uplink transmission process can be: 1) The process of resuming the suspended RRC connection, such as the terminal sending a traditional RRCResumeRequest message to the network device and waiting for the RRC message reply from the network device; or 2) the SDT process, such as the terminal side has nothing to send at this time For uplink data, the terminal triggers the execution of the SDT process or the MT (terminal called) SDT process, or the terminal side has only small data packets to be sent in the uplink at this time, which conforms to the SDT sending rules, so the terminal triggers the execution of the SDT process.

Further, the terminal can determine whether to specifically adopt 1) or 2) based on the network side configuration. For example, the network side configuration "When the terminal actively triggers the execution of the uplink transmission process due to the arrival of downlink services, the terminal adopts the MT SDT process". After the terminal receives this configuration, the uplink transmission process adopts the MT SDT process; another example is the network side configuration " The Data Radio Bearer identity (DRB ID) corresponding to the downlink service = 1”, and DRB ID = 1 is SDT RB, so when the terminal actively triggers the uplink transmission process due to the arrival of the downlink service, the terminal uses SDT process.

Step 44: The RAN side device receives the uplink message sent by the terminal.

The uplink message can carry the establishment reason or the recovery reason (the reason for restoring the RRC connection), For example, it can be MT, or MO signaling, or a new reason, such as the reason for downlink traffic arriving at the RAN side, or the reason for periodic downlink traffic arriving at the RAN side.

Step 45: The RAN side device makes a relevant response based on the uplink message and the arrival of the first downlink service, which depends on the implementation of the RAN side device.

For example, the RAN side device sends an RRCResume message to the terminal based on the received uplink message and received downlink service. The terminal enters the RRC connection state and sends DL services in the RRC connection state;

Or the RAN side device receives the uplink message, but the downlink service has not yet arrived. The RAN side device decides to transfer the terminal to the RRC connection state first, so the RAN side device first sends an RRCResume message to the terminal and waits for the arrival of the downlink service;

Or after receiving the uplink message, the RAN side device keeps the terminal in the RRC inactive state and performs related uplink/downlink message transmission during the SDT process.

Embodiment 2 (see Figure 5):

Step 51: Based on its own algorithm or inter-layer interaction, the terminal obtains the period during which the first downlink service to be received reaches the RAN side;

Step 52: The terminal periodically actively triggers the execution of the uplink transmission process at the periodic moment when the first downlink service reaches the RAN side;

Step 53: The RAN side device receives the uplink message sent by the terminal;

Step 54: The RAN side device makes a relevant response based on the uplink message and the arrival of the first downlink service, which depends on the implementation of the RAN side device.

Embodiment 3 (see Figure 6):

Step 61: The RAN side device obtains the time when the first downlink service arrives at the RAN side from the higher layer or based on its own algorithm;

Step 62: The RAN side device notifies the terminal receiving the first downlink service in advance through a message;

Step 63: When the first downlink service reaches the RAN side, the terminal actively triggers the execution of the uplink transmission process;

Step 64: The RAN side device receives the uplink message sent by the terminal;

Step 65: The RAN side device makes a relevant response based on the uplink message and the arrival of the first downlink service, which depends on the implementation of the RAN side device.

Embodiment 4 (see Figure 7):

Step 71: The terminal obtains the time when the first downlink service to be received reaches the RAN side based on its own algorithm or inter-layer interaction.

Step 72: When the first downlink service reaches the RAN side, the terminal actively triggers the execution of the uplink transmission process.

Step 73: The RAN side device receives the uplink message sent by the terminal;

Step 74: The RAN side device makes a relevant response based on the uplink message and the arrival of the first downlink service, which depends on the implementation of the RAN side device.

Embodiment 5 (please refer to Figure 8)

Step 81: Based on its own algorithm, the AMF obtains the time and/or period when the first downlink service reaches the UPF.

Step 82: The AMF notifies the terminal receiving the first downlink service in advance through a message.

Step 83: When the first downlink service reaches the UPF, the terminal actively triggers the execution of the uplink transmission process.

Optionally, the terminal executes the UAC process during the uplink transmission process. If the UAC result is that the terminal is allowed to trigger the execution of the uplink transmission process, the terminal triggers execution of subsequent uplink messages. The uplink message may be an RRC connection establishment request message, including the establishment reason, which may be MT, or a new reason, such as the reason for the downlink service arriving at the core network, or the reason for the periodic downlink service arriving at the core network.

Step 84: The RAN side device receives the RRC connection establishment request sent by the terminal.

Step 85: The RAN side device sends an RRC establishment message to the terminal.

Step 86: The terminal sends an RRC connection establishment completion message to the RAN side device.

Optionally, the message includes a terminal identifier, which is used to assist the RAN side device in selecting the AMF.

Step 87: The RAN side device sends an initialization terminal message (INITIAL UE MESSAGE) to the AMF.

Optionally, the INITIAL UE MESSAGE message includes that the reason is MT, or the terminal side actively triggers the execution of the uplink transmission process because the downlink service reaches the network side (or core network), or the downlink service reaches the core network, or periodic downlink service Arrive at the core network.

Step 88: AMF makes relevant responses based on the received message, depending on the AMF implementation. now.

For example, the AMF will cancel the CN paging for the terminal, or the AMF will establish the context of the terminal with the RAN side device, etc.

Please refer to Figure 9, which is a flow chart of a paging processing method provided by an embodiment of the present disclosure. As shown in Figure 9, the paging processing method includes the following steps:

Step 901: When the anchor node of the terminal triggers RAN paging for the terminal, the network node receives the target message sent by the anchor node, where the target message includes the characteristic information of the downlink service and the characteristic information of the uplink service. at least one of;

Step 902: The network node determines to delay initiating the RAN paging process for the terminal according to the target message.

For inactive terminals, the RAN-side device (i.e., anchor node) that stores the context of the terminal may trigger network nodes (such as adjacent nodes or the entire RAN-based Notification Area allocated to the terminal). , the RAN side node within the RNA) initiates RAN paging for the terminal.

In this embodiment, when the anchor node of the terminal triggers RAN paging for the inactive terminal, the anchor node may inform the network node of the terminal's downlink service characteristics and/or uplink service characteristics. The network node can perform paging optimization or process optimization based on this configuration. For example, network nodes can delay initiating RAN paging based on downlink service characteristics. When the network node does not receive the RRC recovery request for the terminal within a certain period of time, nor the RAN paging cancellation request sent by the anchor node, the network node initiates RAN paging for the terminal. Alternatively, the network node may decide whether to keep the terminal in the RRC inactive state or transfer the terminal to the RRC connected state when receiving the RRC recovery request from the terminal based on the downlink service characteristics and/or the uplink service characteristics.

It should be noted that the characteristic information of the downlink service may refer to the time information when the downlink service reaches the anchor node, and the characteristic information of the uplink service may refer to the time information when the terminal triggers the execution of the uplink transmission process in the non-connected state.

In some embodiments, the paging processing method further includes at least one of the following:

If the network node does not receive the RRC recovery request sent by the terminal within the first preset time, the network node determines to initiate a RAN paging process for the terminal;

The network node does not receive the RAN paging sent by the anchor node within the second preset time. In the case of canceling the instruction, the network node determines to initiate a RAN paging process for the terminal;

When the network node receives the RRC recovery request sent by the terminal, the network node determines to keep the state of the terminal in the non-connected state;

When the network node receives the RRC recovery request sent by the terminal, the network node determines to switch the state of the terminal from the non-connected state to the connected state.

This embodiment can realize paging optimization of network nodes, and can appropriately reduce signaling overhead and power consumption of network nodes.
