Description

Technical Field

[0001] The present application belongs to the field of communication technology, and specifically relates to a service processing method, device, terminal and medium. Background Art

[0002] Most of the power consumption of the New Radio (NR) network comes from the base station. Depending on the actual load, the base station can implement different degrees of energy-saving measures, such as shutting down the base station, shutting down the carrier / cell, shutting down the channel, shutting down the synchronization signal block (SSB) / beam, shutting down the antenna / panel, cell discontinuous transmission (cell DTX) and / or cell discontinuous reception (cell DRX), CSI (Channel State Information) adaptation, etc.

[0003] In the cell DTX / DRX network energy-saving mode, the user equipment (UE) can be configured with periodic cell DTX and / or cell DRX configuration, which includes the active time and non-active time of cell transmission and / or reception. The base station can save network power consumption during the non-active period of the cell. Cell DTX and cell DRX can be configured independently. When a cell is configured with cell DTX, the UE does not monitor the PDCCH (Physical Downlink Control Channel) and SPS (Semi-Persistent Scheduling) during the non-active period on this cell. When a cell is configured with cell DRX, the UE does not send CG (Configured Grant) and SR (Scheduling Request) during the non-active period of this cell.

[0004] However, the relevant technologies have not yet provided a solution to prevent specific services of UE (eg, emergency services, public safety-related services, delay-sensitive services, etc.) from being affected by network energy-saving operations performed by network-side devices. Summary of the invention

It should be noted that in the embodiments of the present application, only the base station in the NR system is used as an example for introduction, and the specific type of the base station is not limited.

[0040] To facilitate understanding of the technical solutions provided by the present application, the main technical concepts involved in the embodiments of the present application are briefly described below.

[0041] Conditional handover (CHO):

[0042] Conditional switching refers to the switching performed by the terminal when the switching execution conditions are met. The main steps are:

[0043] Step 0: UE reports measurement report;

[0044] Step 1: The source base station decides to use CHO. The source base station sends a handover request message to one or more candidate base stations, requesting to configure multiple candidate target cells;

[0045] Step 2: The source base station receives a handover request response message, which includes configuration information of one or more candidate target cells;

[0046] Step 3: The source base station sends a radio resource control (RRC) reconfiguration message to the UE, including a CHO configuration, where the CHO configuration includes the configuration information of the candidate target cell and the corresponding execution conditions (for details about the CHO configuration, see below);

[0047] Step 4: After receiving the CHO configuration, the terminal starts evaluating the execution conditions of each candidate target cell and sends an RRC reconfiguration completion message to the source base station;

[0048] Step 5: If all measIds of a candidate target cell satisfy the corresponding event (for example, event A3 or A5), the UE considers this candidate target cell to be a triggered cell. The UE determines a selected cell in the triggered cell and performs conditional switching on the cell. Specifically, the terminal applies the RRC reconfiguration message of the cell, initiates random access on the cell, and sends an RRC reconfiguration completion message to the cell. When the terminal starts to establish synchronization with the cell, the terminal stops monitoring the source cell. The terminal stops condition evaluation after performing the switching and releases the CHO configuration;

[0049] Step 6: The target base station notifies the source base station that the terminal handover is successful;

[0050] Step 7: The source base station notifies other candidate base stations of the handover cancellation.

[0051] CHO Configuration:

[0052] The CHO configuration includes the configuration information of multiple candidate target cells. Specifically, the network side device configures an execution condition and an RRC reconfiguration message for each candidate target cell, which is identified by a CHO id. The execution condition consists of 1 or 2 measIds, and the measId points to the measId in the RRM (Radio Resource Management) measurement configuration measConfig, that is, the UE can obtain the trigger condition Cond trigger event corresponding to this measId according to the measId and measConfig. The CHO configuration supports deletion, addition and modification, and the execution condition and RRC reconfiguration corresponding to each candidate target cell can be modified.

[0053] CHO execution conditions: Currently, CHO does not support the configuration of A4 measurement events alone. It only supports the configuration of A3 events, A5 events, simultaneous configuration of Ax (A3 or A4 or A5) and T1 events, and simultaneous configuration of Ax (A3 or A4 or A5) and D1 events.

[0054] About the event:

[0055] Event A3: indicates that the quality of the same-frequency / different-frequency neighboring cell is higher than the quality of the serving cell by an offset.

[0056] Event A4: indicates that the quality of the inter-frequency neighboring cell is higher than a certain threshold.

[0057] Event A5: indicates that the quality of the serving cell is lower than a certain threshold and the quality of the neighboring cell is higher than a certain threshold.

[0058] Event T1: indicates that the time measured by the terminal is within a certain time interval;

[0059] Event D1: indicates that the distance between the terminal's position and the reference point is within a given interval.

[0060] In the related art, the network side device will put the capacity cell in the network energy saving mode, or in the network energy saving mode of cell DTX and / or cell DRX, to save power consumption when there is basic coverage. When the current serving cell is a capacity cell and is in the network energy saving mode, or in the network energy saving mode of cell DTX and / or cell DRX, once the base station recognizes that the first service of the UE (for example, a high priority service) appears in the current serving cell, the base station should ensure that the first service of the UE is not affected.

[0061] If the base station identifies the first service of the UE during the active period of the current service cell, on the one hand, the base station needs to deactivate the network energy-saving mode of cell DTX and / or cell DRX, or release the network energy-saving mode configuration of cell DTX and / or cell DRX, thereby affecting the energy-saving gain of the base station. On the other hand, the UE needs to wait until the current service cell enters the active period before initiating the first service, further increasing the latency of the first service. Of course, the network-side device can also choose to switch the UE to a normal neighboring cell, but the switching process requires the UE to report the measurement results and the network-side device to issue a switching command, resulting in a large latency of the UE's first service.

[0062] In response to the problems existing in the related technology, the present application provides a service processing method, which can ensure that the UE's first service is not affected by the energy-saving operation performed by the network side device, thereby reducing the delay of the UE's first service.

[0063] The following, in conjunction with the accompanying drawings, describes in detail the service processing method, device, terminal and medium provided in the embodiments of the present application through some embodiments and their application scenarios.

[0064] First, see Figure 2 , Figure 2 A flowchart of a business processing method provided in an embodiment of the present application is shown. Figure 2 As shown, the method comprises the following steps:

[0065] Step S101: When a user equipment UE has a first service and a current serving cell cannot serve the first service, the UE changes a serving cell.

[0066] The first service may be configured by the network side device for the UE in advance through non-access stratum (NAS) signaling or RRC signaling, or the first service is agreed upon by the protocol. In specific implementation, any service that does not want to be affected by the energy-saving operation of the network side device may be used as the first service. Specifically, the first service may be a high-priority service, such as an emergency service, a public safety-related service, a delay-sensitive service, etc.

[0067] The UE having the first service may include: the UE's first service occurring, the UE's first service initiating, or the UE's first service being ongoing. The first service may be an uplink service or a downlink service. If it is a downlink service, the network side device may indicate the service type of the downlink service to the UE through a paging message.

[0068] The current serving cell being unable to serve the first service includes at least one of the following:

[0069] The current serving cell supports a network energy saving feature;

[0070] The current serving cell is in a network energy-saving state;

[0071] The current serving cell is in a network energy-saving mode of cell discontinuous transmission and / or cell discontinuous reception;

[0072] The UE has the first service during a non-active period of the current serving cell;

[0073] The UE initiates the first service when the remaining non-active duration of the current serving cell exceeds the target duration.

[0074] The UE can determine whether the current serving cell supports the network energy saving feature, whether it is in the network energy saving state, whether it is in the cell DTX / DRX mode, or whether the first service is executed during the non-active period of the cell DTX / DRX mode through the indication information in the broadcast message or the dedicated signaling (such as the RRC release message).

[0075] When the UE has a first service and the current serving cell cannot serve the first service, in order to ensure efficient processing of the UE's first service, the UE can change the serving cell. In this way, the first service can be processed by the changed serving cell, ensuring that the UE's first service is not affected by the energy-saving operation performed by the network side device.

[0076] The present application proposes that when the UE is in a radio resource control RRC connection state, the UE has a first service and the source service cell cannot serve the first service, the UE switches to a target service cell. In this way, the source service cell can continue to remain in a network energy-saving state, or continue to remain in a cell DTX and / or cell DRX network energy-saving mode. This ensures that the UE's first service is not affected by the energy-saving operation performed by the network-side device without sacrificing the network energy-saving gain, thereby reducing the latency of the UE's first service.

[0077] In a specific implementation, if the UE has a first service during the non-active period of the source service cell, or if the UE initiates the first service when the remaining non-active duration of the source service cell exceeds the target duration, the UE can switch to the target service cell. The target service cell can be a coverage cell that does not turn on the network energy-saving mode. In this way, the source service cell can continue to remain in the network energy-saving state, or continue to remain in the cell DTX and / or cell DRX network energy-saving mode. That is, in the present application, the UE does not need to wait until the source service cell enters the active period to initiate the first service. Even if the UE's first service occurs during the non-active period of the source service cell, the UE switches to the target service cell so that the UE's first service can be efficiently processed by the target service cell, thereby reducing the latency of the UE's first service.

[0078] When the UE is in a radio resource control (RRC) connection state and there is a first service and the source service cell cannot serve the first service, if the UE is configured with a conditional switching CHO configuration, the UE determines the target service cell from at least one candidate target cell included in the CHO configuration and switches to the target service cell.

[0079] In specific implementation, the network side device can configure CHO (i.e., one or more candidate target cells and corresponding access configuration information) for the connected UE in advance. When the source service cell cannot serve the UE's first service, the UE is triggered to perform conditional switching. The UE selects one from the candidate target cells as the target service cell according to the CHO configuration and switches to the target service cell to ensure that the UE's first service is not affected.

[0080] It should be noted that the candidate target cell may also be described as a target candidate cell (target candidate cell), or a candidate cell, or a candidate primary and secondary cell, etc. The target candidate cell may refer to a candidate target cell for CPC change.

[0081] The target serving cell is a candidate target cell that satisfies at least one of the following conditions:

[0082] The quality of the candidate target cell meets the preset quality threshold;

[0083] The candidate target cell can serve the first service, and the candidate target cell can serve the first service including at least one of the following:

[0084] The candidate target cell does not support the network energy saving feature;

[0085] The candidate target cell is not in a network energy-saving state;

[0086] The candidate target cell is not in a network energy saving mode of cell discontinuous transmission and / or cell discontinuous reception.

[0087] In this embodiment, when the UE needs to switch (when the UE has a first service and the source service cell cannot serve the first service), the candidate target cell that satisfies at least one of the above conditions can be selected from multiple candidate target cells in the CHO configuration as the target service cell. This embodiment selects the candidate target cell that can serve the first service as the target service cell by screening the cells to be switched, so that the UE can continue to process the first service after switching to the target service cell, ensuring that the first service of the UE can be efficiently processed by the target service cell after the UE changes the service cell, thereby reducing the delay of the first service of the UE.

[0088] In a specific implementation, the service processing method proposed in this embodiment also includes: the UE receives a first indication information sent by a network side device, and the first indication information is used to indicate whether the UE is allowed to have the first service and when the source service cell cannot serve the first service, the UE switches to the target service cell.

[0089] In specific implementation, the UE can only switch to the target service cell if the network side device allows it. Specifically, the network side device sends a first indication message to the UE. If the first indication message indicates that the UE is allowed to switch to the target service cell, the UE switches to the target service cell when the UE has a first service and the source service cell cannot serve the first service; if the first indication message indicates that the UE is not allowed to switch to the target service cell or the UE does not receive the first indication message, the UE cannot switch to the target service cell even if the UE has a first service and the source service cell cannot serve the first service.

[0090] In an optional implementation, the first indication information may be represented in the form of 1 bit. For example, when the first indication information is 1, it indicates that the UE is allowed to switch to the target service cell to process the first service in the target service cell. When the first indication information is 0, it indicates that the UE is not allowed to switch to the target service cell.

[0091] The service processing method when the terminal is in a radio resource control RRC connected state proposed in the above embodiment is explained through the following example.

[0092] Example 1

[0093] Step 1: The UE is in the RRC connected state and is configured with CHO. The UE's current serving cell is the source serving cell, and the cell in the CHO configuration is called the candidate target cell.

[0094] Step 2: The UE receives a cell DTX and / or cell DRX activation command of the source service cell. For example, the UE receives the cell DTX and / or cell DRX configuration of the source service cell and activates it immediately after configuration; or, the UE receives an activation command of the cell DTX and / or cell DRX configuration of the source service cell. The UE sends and receives messages in the source service cell according to the activated cell DTX pattern and / or cell DRX pattern.

[0095] Step 3: The UE receives the first indication information sent by the network side device.

[0096] Step 4: The UE initiates a first service (eg, an emergency call), and determines that the source serving cell cannot serve the first service, and the UE determines a target serving cell from candidate target cells.

[0097] Step 5: After the UE handover is completed, the target serving cell processes the first service of the UE.

[0098] Through the above examples, the source service cell can continue to maintain a network energy-saving state, or continue to maintain a network energy-saving mode of cellDTX and / or cell DRX. When the first service occurs, the UE switches to the target service cell in time, and the target service cell can efficiently process the first service of the UE, thereby ensuring the processing efficiency of the UE's first service without sacrificing the network energy-saving gain, and reducing the delay of the UE's first service.

[0099] When the UE is in the RRC idle IDLE state or the RRC inactive INACTIVE state, the connection establishment triggered by the UE's first service (such as a high priority service) will affect the network energy saving state of the current cell, or interrupt the network energy saving mode of the current cell using cell DTX and / or cell DRX, thereby affecting the network energy saving gain of the current cell.

[0100] The present application proposes that, when the current resident cell is in a network energy-saving state, or in a network energy-saving mode of (activating) cell DTX and / or cell DRX, the UE is redirected to the target cell for resident, so as to ensure that the UE's first service can be efficiently processed when it occurs. Specifically, when the UE is in an RRC idle IDLE state or an RRC inactive INACTIVE state, and the UE has a first service and the current resident cell cannot serve the first service, the UE is redirected to the target cell for resident. In this way, the current resident cell can continue to remain in a network energy-saving state, or continue to remain in a network energy-saving mode of cell DTX and / or cell DRX, thereby ensuring the processing efficiency of the UE's first service without sacrificing the network energy-saving gain, and reducing the latency of the UE's first service.

[0101] In specific implementation, if the UE has a first service during the non-active period of the current cell, or if the UE initiates the first service when the remaining non-active duration of the current cell exceeds the target duration, the UE can be redirected to the target cell for residence. The target cell does not support the network energy-saving feature (for example, the target cell can be a coverage cell). In this way, the current cell can continue to remain in the network energy-saving state, or continue to remain in the network energy-saving mode of cell DTX and / or cell DRX. That is, in the present application, the UE does not need to wait until the current cell enters the active period to initiate the first service. Even if the UE's first service occurs during the non-active period of the current cell, the connection establishment triggered by the first service will not affect the network energy-saving state of the current cell. The UE can be redirected to the target cell for residence, so that the UE's first service can be efficiently processed by the target cell, thereby reducing the latency of the UE's first service.

[0102] In an optional implementation, the UE receives a first message, where the first message includes:

[0103] Indication information indicating that the current resident cell supports network energy saving features;

[0104] Indication information indicating that the current resident cell is in a network energy-saving state;

[0105] Indication information indicating that the currently camped cell is in a network energy saving mode of cell discontinuous transmission and / or cell discontinuous reception.

[0106] Specifically, the first message may be used to indicate that the current resident cell temporarily does not support (or cannot serve) the first service, or may be used to indicate that the current resident cell is in a network energy-saving state, or indicates that the current resident cell is in (or has turned on) a cell DTX and / or cell DRX network energy-saving mode, or indicates the cell DTX / DRX configuration of the current resident cell.

[0107] Optionally, the first message may be a short message or a broadcast message.

[0108] This embodiment proposes that when the UE is in the RRC idle IDLE state or the RRC inactive INACTIVE state, the UE has a first service. If the UE receives a first message indicating that the current resident cell cannot serve the first service, the UE is redirected to the target cell. This avoids the connection establishment triggered by the UE's first service from affecting the network energy-saving state of the current resident cell, or interrupting the network energy-saving mode of the current resident cell using cell DTX and / or cell DRX, thereby reducing the latency of the UE's first service without sacrificing the network energy-saving gain.

[0109] The service processing method when the terminal is in the RRC idle IDLE state or the RRC inactive INACTIVE state proposed in the above embodiment is explained through the following example.

[0110] Example 2

[0111] Step 1: The UE is in the RRC IDLE state or the RRC INACTIVE state.

[0112] Step 2: The UE receives the first message, and determines according to the first message that the current resident cell cannot serve the first service of the UE.

[0113] Step 3: The UE initiates a first service (eg, an emergency call).

[0114] Step 4: The UE is redirected to the target cell to camp on it.

[0115] Step 5: The UE initiates RRC connection establishment in the target cell to process the first service.

[0116] This embodiment proposes that the UE receives a first configuration sent by a network side device, where the first configuration is used to indicate information about a neighboring cell that can serve the first service.

[0117] The neighboring cell being able to serve the first service includes at least one of the following:

[0118] The neighboring cell does not support the network energy saving feature;

[0119] The neighboring cell is not in a network energy-saving state;

[0120] The neighboring cell is not in a network energy-saving mode of cell discontinuous transmission and / or cell discontinuous reception.

[0121] In a specific implementation, the first configuration is used to indicate whether the neighboring cell of the current resident cell can process the first service of the UE (for example, whether the neighboring cell is in a network energy saving state, or in a cell DTX and / or cell DRX network energy saving mode).

[0122] The neighboring cell information includes at least one of the following:

[0123] A list of neighboring cells that can provide the first service;

[0124] Whether the frequency point of the neighboring cell that can serve the first service is located;

[0125] Whether the radio access technology (Radio Access Technology, RAT) of the neighboring cell that can serve the first service is located.

[0126] The UE receiving a first configuration sent by a network side device includes:

[0127] The UE receives a broadcast message carrying the first configuration; or

[0128] The UE receives an RRC release message carrying the first configuration.

[0129] In specific implementation, when the terminal is in the RRC idle IDLE state / RRC inactive INACTIVE state, it can receive a broadcast message carrying a first configuration, and the first configuration in the broadcast message can be used to indicate information and / or frequency list information of cells that do not support network energy saving (i.e., can serve the first service).

[0130] When the terminal is released to the RRC idle IDLE state / RRC inactive INACTIVE state, it can receive an RRC release message carrying a first configuration, where the first configuration in the RRC release message is used to indicate information and / or frequency list information of cells that do not support network energy saving (ie, can serve the first service).

[0131] In an optional embodiment,

[0132] In a case where the UE receives the first configuration sent by the network side device, redirecting the UE to a target cell for camping includes:

[0133] The UE performs cell reselection measurement according to the first configuration to obtain a measurement result;

[0134] The UE performs cell reselection according to the measurement result.

[0135] In a specific implementation, when the UE is in an RRC idle IDLE state or an RRC inactive INACTIVE state, and the UE initiates a first service and the current resident cell cannot serve the first service, when the UE performs cell reselection measurement, if the UE receives a first configuration sent by a network side device, the cell reselection measurement can be performed according to the received first configuration; if the UE does not receive the first configuration sent by the network side device, the cell reselection measurement process in the related technology can be performed. That is, the first configuration sent by the network side device is information that the UE can select when performing cell reselection measurement.

[0136] The UE performs cell reselection measurement according to the first configuration sent by the network side device, including: the UE performs cell reselection measurement only on the neighboring cells included in the first configuration, or the UE preferentially performs cell reselection measurement on the neighboring cells included in the first configuration.

[0137] In a specific implementation, the UE may perform cell reselection measurements only for the neighboring cells included in the first configuration, and no longer perform cell reselection measurements on other cells. Exemplarily, the first configuration indicates information about 10 neighboring cells, and the UE only performs cell reselection measurements on these 10 neighboring cells. Alternatively, the UE preferentially performs cell reselection measurements on the neighboring cells included in the first configuration, and then performs cell reselection measurements on other cells. Exemplarily, the first configuration received by the UE indicates information about 10 neighboring cells, and the UE preferentially performs cell reselection measurements on the 10 neighboring cells in the first configuration, and when the signal quality of the 10 neighboring cells is poor, the UE performs cell reselection measurements on other cells.

[0138] In another optional implementation, when the UE receives the first configuration sent by the network side device, the UE is redirected to the target cell to reside, including: the UE performs cell reselection according to the first configuration.

[0139] The UE performing cell reselection according to the first configuration includes: if the neighboring cell included in the first configuration satisfies a preset condition, the UE reselects to the neighboring cell that satisfies the preset condition, wherein the preset condition includes at least one of the following:

[0140] Satisfy the S criteria;

[0141] Meeting a preset signal quality threshold;

[0142] The neighboring cell is capable of serving the first service.

[0143] Among them, the preset signal quality threshold may be agreed upon by the protocol or configured on the network side. The preset signal quality threshold is used to determine whether the neighboring cell meets the reselection condition only when the UE has a first service and the current resident cell cannot serve the first service. In a specific implementation, when the UE is in the RRC idle IDLE state or the RRC inactive INACTIVE state, and the UE initiates a first service and the current resident cell cannot serve the first service, when the UE performs cell reselection, if the first configuration sent by the network side device is received, the cell reselection can be performed according to the received first configuration; if the first configuration sent by the network side device is not received, the cell reselection process in the related technology can be executed. That is, the first configuration sent by the network side device is information that the UE can select when performing cell reselection.

[0144] In a specific implementation, the UE reselects a target cell from the neighboring cells indicated by the first configuration, and the reselected target cell is the target cell to which the UE is redirected.

[0145] The following example three is used to illustrate the broadcast-based redirection method proposed in the above embodiment when the terminal is in the RRC idle IDLE state or the RRC inactive INACTIVE state.

[0146] Example 3

[0147] Step 1: The UE is in the RRC IDLE state or the RRC INACTIVE state.

[0148] Step 2: The current resident cell is in a network energy saving state, or the current resident cell is in a network energy saving mode of cell DTX and / or cell DRX.

[0149] Step 3: The UE initiates a first service (eg, an emergency call), and determines that the current camping cell cannot serve the first service of the UE (this can be determined by receiving a first message).

[0150] Step 4: The UE is redirected to a target cell (the target cell may be the target cell reselected in step 7 below) to reside, and the target cell processes the first service.

[0151] Optionally, also include:

[0152] Step 5: The UE receives the first configuration.

[0153] Step 6: The UE performs cell reselection measurement according to the first configuration, and obtains a measurement result of the cell reselection measurement.

[0154] Step 7: The UE performs cell reselection according to the first configuration. The UE may perform cell reselection according to the measurement result of the cell reselection measurement obtained in step 6, and the reselected target cell is the target cell redirected in step 4.

[0155] The following example 4 is used to illustrate the RRC release-based redirection method when the terminal is in the RRC inactive INACTIVE state proposed in the above embodiment.

[0156] Example 4

[0157] Step 1: The UE is in the RRC INACTIVE state.

[0158] Step 2: The UE initiates a first service (eg, an emergency call), triggering an RRC connection recovery procedure.

[0159] Step 4: The UE sends an RRC connection recovery request message, in which the establishment cause value carried indicates the first service.

[0160] Step 5: The UE receives an RRC release message, which carries the first configuration.

[0161] Step 6: The UE performs cell reselection (which can be understood as redirection) according to the first configuration, and initiates RRC connection recovery on the reselected target cell.

[0162] Step 7: The UE enters the RRC connected state, and the target cell processes the first service of the UE.

[0163] Implementation Method 4

[0164] This implementation describes an example of a method for executing service processing at the RRC layer of a terminal.

[0165] In this embodiment, the RRC layer of the UE receives a first notification message sent by a high layer, and the first notification message is used to notify the UE to initiate the first service; and / or the RRC layer of the UE receives a second notification message sent by a low layer, and the second notification message is used to notify the current service cell to enter a network energy-saving state, or to be in a network energy-saving mode of discontinuous cell transmission and / or discontinuous cell reception; the RRC layer of the UE determines whether to change the service cell based on the first notification message and / or the second notification message.

[0166] Reference Figure 3 , Figure 3 A flowchart of the steps of determining whether to change the serving cell in a service processing method is shown. Figure 3As shown, the RRC layer executes step S301 to receive a first notification message sent by a high layer; the RRC layer executes step S302 to receive a second notification message sent by a low layer; there is no sequence relationship between step S301 and step S302. Then, the RRC layer executes step S303 to determine whether to change the serving cell according to the first notification message and the second notification message.

[0167] In this embodiment, the physical layer is the lowest layer, the protocol layers higher than the RRC layer are collectively referred to as the high layer, and the protocol layers lower than the RRC layer including the physical layer are collectively referred to as the low layer. When the UE is in the radio resource control RRC connected state, the RRC idle IDLE state or the RRC inactive INACTIVE state, the UE has a first service (e.g., a high priority service), and the high layer sends a first notification message to the RRC layer.

[0168] When the UE is in a radio resource control (RRC) connected state, when the source service cell enters a network energy-saving state, or is in a network energy-saving mode of cell discontinuous transmission and / or cell discontinuous reception, a second notification message is sent from the lower layer to the RRC layer. Exemplarily, the UE detects that the source service cell has activated cell DTX or cell DRX, and the physical layer of the UE receives a cellDTX or cell DRX activation command, and the physical layer notifies the RRC layer of the information as a second notification message. When the UE is in an RRC idle IDLE state or an RRC inactive INACTIVE state, when the current resident cell enters a network energy-saving state, or is in a network energy-saving mode of cell discontinuous transmission and / or cell discontinuous reception, a second notification message (for example, a cell DTX or cell DRX activation command of the current resident cell) is sent from the lower layer to the RRC layer.

[0169] In specific implementation, the RRC layer of the UE determines whether to change the service cell based on the received first notification message and / or second notification message. Specifically, when the RRC layer of the UE determines that the UE initiates the first service based on the first notification message, and determines that the current service cell cannot serve the first service based on the second notification message, the RRC layer determines that it needs to switch to the target service cell, or redirect to the target cell. In this embodiment, the RRC layer of the UE determines whether to change the service cell based on the received first notification message and / or second notification message, so that the UE can change the service cell in time when initiating the first service, and the current service cell can continue to remain in the network energy-saving state, or continue to remain in the network energy-saving mode of cell DTX and / or cellDRX, so as to ensure the processing efficiency of the UE's first service without sacrificing the network energy-saving gain, and reduce the latency of the UE's first service.

[0170] In an optional implementation, the method also includes: the RRC layer of the UE sends a third notification message to the upper layer, and the third notification message is used to notify the current service cell to enter a network energy-saving state, or to be in a network energy-saving mode of discontinuous cell transmission and / or discontinuous cell reception.

[0171] In a specific implementation, when the current serving cell enters a network energy-saving state, or is in a network energy-saving mode of cell discontinuous transmission and / or cell discontinuous reception, a second notification message (e.g., a Cell DTX or cell DRX activation command of the current serving cell) is sent by the lower layer to the RRC layer, and a third notification message is sent by the RRC layer to the upper layer to notify the UE that the current serving cell enters a network energy-saving state, or is in a network energy-saving mode of cell discontinuous transmission and / or cell discontinuous reception. Optionally, the third notification message includes network energy-saving mode information of cell discontinuous transmission and / or cell discontinuous reception, such as cell DTX / DRX pattern information, and the RRC layer indicates the cell DTX / DRX pattern of the current serving cell to the upper layer by sending the third notification message, so that the UE sends and receives messages in the current serving cell according to the cell DTX / DRX pattern.

[0172] The following Example 5 is used to illustrate an example of the method for performing service processing at the RRC layer of the terminal proposed in the above embodiment.

[0173] Example 5

[0174] Step 1: The physical layer of the UE receives an activation command of cell DTX and / or cell DRX, and sends a second notification message to the RRC layer.

[0175] Step 2: The RRC layer of the UE sends a third notification message to the higher layer, indicating that the current serving cell has activated the cell DTX and / or cell DRX network energy saving mode. The third notification message may also include cell DTX / DRX pattern information.

[0176] Step 3: When the UE initiates the first service, the upper layer sends a first notification message to the RRC layer.

[0177] Step 4: The RRC layer determines, based on the received first notification message and / or second notification message, that the first service is currently occurring and that the current serving cell cannot serve the first service and that the serving cell needs to be changed.

[0178] Step 7: The UE changes the serving cell.

[0179] Optionally, the present application also proposes a method for cell DTX / DRX transmission:

[0180] At present, the activation / deactivation command of cell DTX / DRX may be sent to the UE via multicast. In the case that the UE cannot confirm the receipt of the multicast command to the network side device, the network side device cannot know that the UE has lost the cell DTX / DRX command, which leads to inconsistent understanding of the cell DTX / DRX activation and cell DTX / DRX inactivation time between the UE and the network side device, resulting in transmission abnormality or unnecessary power consumption of the UE.

[0181] In order to solve this problem, the present application introduces a first timer for automatically activating cell DTX / DRX, or a second timer for automatically deactivating cell DTX / DRX.

[0182] Specifically, for the first timer:

[0183] 1) The condition for the UE to start the first timer includes at least one of the following: immediately after receiving the cell DTX / DRX configuration or after a preset time; immediately after receiving the cell DTX / DRX deactivation command or after a preset time.

[0184] 2) Optionally, after the first timer expires, the UE activates cell DTX / DRX.

[0185] 3) Optionally, if the UE receives a cell DTX / DRX deactivation command during the operation of the first timer, the first timer is restarted;

[0186] 4) Optionally, if the UE receives a first timer stop indication during the running of the first timer, the first timer is stopped; 5) Optionally, when the UE activates cell DTX / DRX, the first timer is stopped.

[0187] In this way, the UE will automatically activate the cell DTX / DRX at most after the first timer times out, thereby avoiding unnecessary power consumption caused by the UE not knowing that the network has activated the cell DTX / DRX and the UE continuing to monitor.

[0188] Specifically, for the second timer:

[0189] 1) The condition for the UE to start the second timer includes at least one of the following: immediately after receiving the cell DTX / DRX configuration or after a preset time; immediately after receiving the cell DTX / DRX activation command or after a preset time.

[0190] 2) Optionally, after the second timer expires, the UE deactivates cell DTX / DRX.

[0191] 3) Optionally, if the UE receives a cell DTX / DRX activation command during the running of the second timer, the second timer is restarted;

[0192] 4) Optionally, if the UE receives a second timer stop indication during the running of the second timer, the second timer is stopped; 5) Optionally, when the UE deactivates cell DTX / DRX, the second timer is stopped.

[0193] In this way, the UE will automatically deactivate the cell DTX / DRX at most after the second timer expires, thereby reducing the time of inconsistency between the UE and the base station and reducing the chance of the UE missing the base station scheduling and transmission abnormality.
