Description

Technical Field

[0001] This application relates to the field of communication technologies, and in particular, to communication methods, communication devices, communication equipment, and computer storage media.

[0002] (Cross-reference to related applications) This application claims the priority of a Chinese patent application with an application number of No. 202210786568.5, filed with the China National Intellectual Property Administration on July 4, 2022, and all of its content is incorporated herein by reference.

Background Art

[0003] Both the network side and the user equipment (UE) can trigger the activation and deactivation of a secondary cell group (SCG) / primary secondary cell (PSCell). Regarding the downlink service reach situation, the network side has more information or pre-judgment ability. At this time, if the UE is not sensitive to power consumption, the activation and deactivation of the PSCell / SCG can be triggered by the network side node. On the other hand, in the case of the arrival or end of an uplink service, especially a sudden large amount of uplink service, or when the UE is sensitive to power consumption (such as low battery power of the UE), it is more reasonable for the UE to trigger the activation and deactivation of the secondary node (SN) / PSCell / secondary cell group (SCG).

Summary of the Invention

Problems to be Solved by the Invention

[0004] Currently, the reporting of UE mobility history information in the case of dual connection does not include information associated with the activation / deactivation of the PSCell or SCG. That is, the network-side node cannot pre-determine the activation / deactivation state of the UE's PSCell or SCG in the case of dual connection. Therefore, it is not possible to better optimize the handover policy for the UE and perform a customized resource configuration.

[0030] Hereinafter, the present application will be described in more detail with reference to the drawings and specific embodiments.

[0031] The technical solutions in the embodiments of the present application can be applied to various communication systems, such as Global System of Mobile communication (GSM) systems, Long Term Evolution (LTE) systems, or 5G systems. Optionally, a 5G system or 5G network may also be referred to as a New Radio (NR) system or NR network.

[0032] Exemplarily, the communication system to which the embodiments of the present application are applied may include network devices and terminal devices (which may also be referred to as terminals, communication terminals, etc.). The network device may be a device that communicates with the terminal device. Here, the network device can provide communication coverage within a certain area and communicate with terminals located within this area. Optionally, the network device may be a base station in each communication system, such as an Evolutional Node B (eNB) in an LTE system, or a base station (gNB) in a 5G system or NR system.

[0033] In the embodiments of the present application, a device with a communication function in a network / system may be referred to as a communication device. The communication device may include network devices and terminals with communication functions. The network devices and terminals may be the specific devices described above and will not be repeatedly described here. The communication device may further include other devices in the communication system, such as other network entities like network controllers, mobile management entities, etc., but the embodiments of the present application do not limit these.

[0034] Note that the terms "system" and "network" in this specification are always used interchangeably in this specification. The term "and / or" in this specification only describes the association relationship of the associated objects and indicates that three relationships can exist. For example, A and / or B can represent three cases: when A exists independently, when both A and B exist, and when B exists independently. Also, the symbol " / " in this specification usually represents that the relationship between the associated objects before and after is an "or" relationship.

[0035] The terms such as "first" and "second" in the description and claims of this application do not limit a specific order or sequence, but are used to distinguish similar objects. Note that since the data used in this way can be exchanged when appropriate, the embodiments of this application described in this specification can be implemented in an order other than those illustrated or described in this specification. Furthermore, the terms "comprising", "having", and their variants are intended to mean non-exclusive inclusion. For example, a process, method, system, product, or device incorporating a series of steps or units need not be limited to those explicitly listed, but may include other things not explicitly listed or inherent to those processes, methods, products, or devices.

[0036] The embodiments of this application provide a communication method applicable to a terminal. FIG. 1 is a flowchart 1 of the communication method according to the embodiments of this application. As shown in FIG. 1, the communication method includes the following steps.

[0037] In step 101, the terminal reports first information associated with the activation or deactivation of a PSCell or SCG, and the first information includes the cell identifier of the PSCell, first indication information as to whether the PSCell or SCG is deactivated, second indication information as to whether the PSCell or SCG has ever been deactivated, duration information of the activation and / or deactivation of the PSCell or SCG. The activation and / or deactivation state of other SCell(s) other than the PSCell within the SCG, Duration information corresponding to the state of other SCell(s) other than the PSCell within the SCG, Network element information indicating the activation or deactivation of the SCG, including at least one of information on whether the network-side configuration permits the terminal's application for activation or deactivation of the SCG.

[0038] Here, optionally, the duration information of the activation and / or deactivation of the PSCell or SCG may specifically be a specific period corresponding to the activation state and / or deactivation state, or may be a ratio of the period corresponding to the activation state and / or deactivation state within a certain time range.

[0039] Optionally, the duration information corresponding to the state of other SCell(s) other than the PSCell within the SCG may specifically be a specific period of the state (activation state and / or deactivation state) of other SCell(s) other than the PSCell within the SCG, or may be a ratio of the period corresponding to the activation state and / or deactivation state within a certain time range.

[0040] Optionally, the network element information indicating the activation or deactivation of the SCG may specifically be a base station, e.g., an MN or an SN, and in other embodiments, the network element information may be a terminal.

[0041] Embodiments of the present application relate to dual - connection scenarios. Dual connection means that a terminal can be simultaneously connected to two base stations, and these two base stations may both be 5G base stations, or one may be a 5G base station and the other may be a 4G base station. Among the two base stations, one is called the Master Node (MN), and the other is called the Secondary Node (SN). In the case of the master node, the corresponding multiple carriers or multiple cells are called the Master Cell Group (MCG). Correspondingly, in the case of the secondary node, the corresponding multiple carriers or multiple cells are called the Secondary Cell Group (SCG). In the case of MCG, the master cell therein is called the Primary cell (PCell), and the secondary cell is called the Secondary cell (SCell). In the case of SCG, the master cell therein is called the Primary Secondary cell (PSCell), and the secondary cell is still called the Secondary cell (SCell).

[0042] In this embodiment, record and report the first information associated with the activation or de - activation of the PSCell or SCG. The first information may also be referred to as the historical information of the terminal or the mobility historical information. In related technical solutions, the mobility historical information of the terminal is usually recorded by the terminal recording the information of the cell where it is resident or has been connected in order to report it to the network side, so as to assist the network side in grasping the past movement trajectory of the terminal. However, the current mobility historical information of the terminal does not include information associated with the activation or de - activation of the PSCell or SCG of the terminal. Therefore, in this embodiment, by reporting the first information associated with the activation or de - activation of the PSCell or SCG by the terminal, the network side can grasp the dual - connection status of the terminal, facilitating the optimization of the switching policy and the optimization of related configurations by the network side. In some alternative embodiments of the present application, the communication method further includes the step of the terminal recording the first information.

[0043] In some alternative embodiments of the present application, the communication method includes a step in which the terminal receives first configuration information transmitted from a network device, where the first configuration information is used to configure or request the terminal to record or report the first information, or a step in which the terminal records the first information according to a predefined protocol.

[0044] In this embodiment, the first information recorded or reported by the terminal may be configured by a network device, that is, the terminal receives the first configuration information transmitted from the network device and records or reports the first information based on the first configuration information. In other embodiments, it may be predefined by a protocol, that is, the terminal records or reports the first information according to a predefined protocol.

[0045] Optionally, the network device is any one of a network management device, a Tracking Collection Entity (TCE), and a base station.

[0046] In this embodiment, when the first configuration information is configured by a network device, the network device may be a network administrator (such as a network management system or a network management device), a TCE, or a base station, where the base station may be an MN or an SN in a dual-connection scenario.

[0047] In this embodiment, the terminal reports the first information to the network device. When the network device is a base station, the terminal directly reports the first information to the network device. When the network device is a network management device or a TCE, the terminal reports the first information to the network device via the base station, that is, the terminal first transmits the first information to the base station, and then the base station transmits the first information to the network management device or the TCE.

[0048] In some alternative embodiments, the step of the terminal reporting first information associated with activation or deactivation of a PSCell or an SCG includes the terminal receiving a first request transmitted from a network device and transmitting the first information to the network device based on the first request, or the terminal spontaneously transmitting the first information to the network device, or the terminal transmitting second information to the network device, receiving a second request transmitted from the network device, and transmitting the first information to the network device based on the second request, where the second information is used to notify that first information associated with activation or deactivation of a PSCell or an SCG has been recorded.

[0049] In this embodiment, as a first embodiment, the terminal reporting first information may specifically be requested by a network - side node. That is, after the terminal receives a first request transmitted from a network device, it transmits the first information to the network device. As a second embodiment, the terminal can also spontaneously report the first information to the network device. As a third embodiment, after the terminal records the first information, it can first notify the network device that the first information has been stored, that is, it can transmit second information to the network device. Further, after the network device transmits a second request, that is, in response to a request from the network side, it reports the first information to the network device. Here, the network device may specifically be a network management device, a TCE, or a base station.

[0050] In some alternative embodiments, the terminal can report the first information in a process such as a handover. Here, the handover process may be, for example, a cell handover process.

[0051] In some alternative embodiments, the communication method further includes a step in which the terminal receives a first command transmitted from a network device, where the first command is used to instruct the terminal to perform base station switching or cell switching. For a terminal for which the duration information corresponding to the active state of the SCG satisfies a first predetermined condition, the first command is used to instruct the terminal to switch to a base station or cell with a load less than a first threshold and capable of dual connection, and / or for a terminal for which the duration information corresponding to the active state of the SCG does not satisfy the first predetermined condition, the first command is used to instruct the terminal to switch to a cell with a communication quality higher than a second threshold.

[0052] In this embodiment, exemplarily, a network device (such as a base station) switches a terminal with a long time corresponding to the active state of the SCG, that is, a terminal that always performs high-speed data transmission, to a target base station that is relatively idle and capable of dual connection, and switches a terminal with a short time corresponding to the active state of the SCG to a cell with high measurement values of RSRP (Reference Signal Receiving Power) and / or RSRQ (Reference Signal Receiving Quality) but a larger load than other adjacent areas, thereby assisting in more effective load distribution on the network side.

[0053] In some other alternative embodiments, the communication method further includes a step in which the terminal receives second configuration information transmitted from a network device, where the second configuration information includes the state of the PSCell or SCG, the duration information corresponding to the state of the PSCell or SCG, the state of other SCell other than the PSCell in the SCG, the duration information corresponding to the state of other SCell other than the PSCell in the SCG, at least one of the information on whether the network-side configuration permits the terminal to apply for activation or deactivation of the SCG.

[0054] In this embodiment, in some embodiments, the network device (such as a base station) configures second configuration information for the terminal according to whether the network element that starts the activation and / or deactivation of the SCG of the terminal during the period of activation and / or deactivation of the previous SCG of the terminal is the base station (MN or SN) or the terminal. The second configuration information includes, for example, the state of the PSCell or SCG, the state of other SCell other than the PSCell within the configured SCG, the time information corresponding to each state, etc. For a terminal with a long activation time of the previous SCG, at the time of handover, in the handover command or radio resource control (RRC) reconfiguration message, the activated PSCell, and further other secondary cells within the SCG, and the corresponding time information can be configured for the terminal (according to rules such as the pattern and period of activation and deactivation of the previous SCG of the terminal). Conversely, for a terminal with a short activation time of the previous SCG, at the time of handover, in the handover command or RRC reconfiguration message, the PSCell or SCG can be configured for the terminal to be in a deactivated state.

[0055] In some other embodiments, the network device (such as a base station) can also determine whether to permit the subsequent application for activation or deactivation of the SCG by the terminal based on whether it has previously permitted the application for activation or deactivation of the SCG by the terminal, or information such as the number of applications and / or application frequency for activation and deactivation of the SCG by the terminal. For example, if the terminal always applies for activation or deactivation of the SCG, but the period during which the terminal is actually in the activated or deactivated state of the SCG after the application is always very short, it means that the application of the terminal is not very reasonable. The network device may not need to configure the terminal to have this ability subsequently. Otherwise, the terminal is configured to be able to apply for activation or deactivation of the SCG.

[0056] Based on the above embodiments, the embodiments of the present application further provide a communication method applied to network devices. FIG. 2 is a flowchart 2 of the communication method according to the embodiments of the present application. As shown in FIG. 2, the communication method includes the following steps.

[0057] In step 201, the network device receives first information associated with the activation or deactivation of a PSCell or SCG reported by a terminal, and the first information includes the cell identifier of the PSCell, first indication information indicating whether the PSCell or SCG is deactivated, second indication information indicating whether the PSCell or SCG has ever been deactivated, activation and / or deactivation duration information of the PSCell or SCG, the activation and / or deactivation status of other SCell other than the PSCell in the SCG, duration information corresponding to the status of other SCell other than the PSCell in the SCG, network element information indicating the activation or deactivation of the SCG, and at least one of information indicating whether the network-side configuration permits the terminal to apply for the activation or deactivation of the SCG.

[0058] Here, optionally, the activation and / or deactivation duration information of the PSCell or SCG may specifically be a specific period corresponding to the activation state and / or deactivation state, or may be a ratio of the period corresponding to the activation state and / or deactivation state within a certain time range.

[0059] Optionally, the duration information corresponding to the state of other SCell other than the PSCell in the SCG may specifically be the specific period of the state (activation state and / or deactivation state) of other SCell other than the PSCell in the SCG, or may be the ratio of the period corresponding to the activation state and / or deactivation state within a certain time range.

[0060] Optionally, the network element information indicating the activation or deactivation of the SCG may specifically be a base station such as an MN or an SN. In other embodiments, the network element information may be a terminal.

[0061] In this embodiment, by the terminal reporting the first information associated with the activation or deactivation of the PSCell or the SCG, the network side can grasp the dual connection status of the terminal, facilitating the optimization of the switching policy and the optimization of related configurations by the network side.

[0062] Optionally, the network device is any one of a network management device, a TCE, and a base station.

[0063] In some alternative embodiments of the present application, the communication method further includes a step of the network device transmitting first configuration information to the terminal, and the first configuration information is used to configure or request the terminal to record or report the first information.

[0064] In some alternative embodiments, before the network device receives the first information associated with the activation or deactivation of the PSCell or SCG reported by the terminal, the communication method includes a step in which the network device sends a first request to the terminal, where the first request is used to request the first information, or the network device receives second information sent by the terminal and sends a second request to the terminal, where the second information is used to notify the terminal that the first information has been recorded, and the second request is used to request the first information.

[0065] In this embodiment, the network device receiving the first information reported by the terminal can specifically include three embodiments. As the first embodiment, the network device sends a first request to the terminal, that is, the network-side node requests the terminal to report the first information. After the terminal receives the first request sent by the network device, the terminal sends the first information to the network device. As the second embodiment, the terminal can also spontaneously report the first information to the network device. As the third embodiment, after the terminal records the first information, the terminal can first notify the network device that the first information has been stored, that is, the network device receives the second information sent by the terminal. Further, the network device requests the terminal to report the first information, that is, sends a second request to the terminal, and receives the first information sent by the terminal. Here, the network device may specifically be a network management device, a TCE, or a base station.

[0066] In some alternative embodiments of the present application, the communication method further includes a step in which the network device optimizes the handover policy of the terminal and / or the configuration associated with the PSCell or SCG based on the first information.

[0067] In this embodiment, the switching policy is specifically a related policy for a terminal to perform cell switching or base station switching. The switching policy may specifically include conditions for performing cell switching or base station switching. For example, when a terminal meets certain conditions, it switches to a cell or base station that meets certain requirements. The configuration associated with the PSCell or SCG may specifically include the configuration of the state of the PSCell or SCG (such as activation and / or deactivation), the duration information of each state, the activation and / or deactivation state of other SCell other than the PSCell in the SCG, the duration information corresponding to the state of other SCell other than the PSCell in the SCG, and the like.

[0068] In some alternative embodiments, the communication method further includes a step in which the network device sends a first command to the terminal based on the switching policy. The first command is used to instruct the terminal to perform base station switching or cell switching. For the terminal for which the duration information corresponding to the active state of the SCG meets a first predetermined condition, the first command is used to instruct the terminal to switch to a base station or cell with a load less than a first threshold and capable of dual connection, and / or for the terminal for which the duration information corresponding to the active state of the SCG does not meet the first predetermined condition, the first command is used to instruct the terminal to switch to a cell with a communication quality higher than a second threshold.

[0069] In this embodiment, illustratively, a network device (such as a base station) switches a terminal with a long time corresponding to the active state of the SCG, that is, a terminal that always performs high-speed data transmission, to a target base station that is relatively idle and capable of dual connection, and can switch a terminal with a short time corresponding to the active state of the SCG to a cell with high measured values of RSRP and / or RSRQ but a larger load than other adjacent areas, thereby assisting in more effective load distribution on the network side.

[0070] In some other alternative embodiments, the communication method further includes a step in which the network device transmits second configuration information to the terminal based on a configuration associated with the PSCell or SCG, and the second configuration information includes the state of the PSCell or SCG, duration information corresponding to the state of the PSCell or SCG, the state of other SCell(s) other than the PSCell within the SCG, duration information corresponding to the state of other SCell(s) other than the PSCell within the SCG, at least one of information on whether the network-side configuration permits the terminal to apply for activation or deactivation of the SCG.

[0071] In this embodiment, in some embodiments, a network device (such as a base station) configures second configuration information for the terminal according to whether the network element that starts the activation and / or deactivation of the SCG is the base station (MN or SN) or the terminal during the period of activation and / or deactivation of the terminal's previous SCG. The second configuration information includes, for example, the state of the PSCell or SCG, the state of other SCell(s) other than the PSCell within the configured SCG, time information corresponding to each state, etc. For a terminal with a long activation and / or deactivation time of the previous SCG, at the time of handover, in the handover command or RRC reconfiguration message, the activated PSCell, and further, other secondary cells within the SCG, and the corresponding time information can be configured for the terminal (in accordance with rules such as the pattern and period of activation and deactivation of the terminal's previous SCG). Conversely, for a terminal with a short activation time of the previous SCG, at the time of handover, in the handover command or RRC reconfiguration message, the PSCell or SCG can be configured for the terminal to be in a deactivated state.

[0072] In some other embodiments, the network device (such as a base station) can also determine whether to permit the terminal's subsequent application for activation or deactivation of the SCG based on whether it could permit the terminal's application for activation or deactivation of the SCG previously, or information such as the number of times and / or frequency of the terminal's application for activation or deactivation of the SCG. For example, if the terminal always applies for activation or deactivation of the SCG, but the period during which the terminal is actually in the activated or deactivated state of the SCG after the application is always very short, it means that the terminal's application is not very reasonable. The network device may not need to configure the terminal to have this capability subsequently. Otherwise, the terminal is configured to be able to apply for activation or deactivation of the SCG.

[0073] The embodiments of the present application further provide a communication method applicable to a first network device. The communication method includes a step in which the first network device transmits first information associated with activation or deactivation of a PSCell or an SCG of a terminal to a second network device. The first information includes the cell identifier of the PSCell, first indication information indicating whether the PSCell or the SCG is deactivated, second indication information indicating whether the PSCell or the SCG has ever been deactivated, duration information of activation and / or deactivation of the PSCell or the SCG, the activation and / or deactivation state of other secondary cells (SCells) other than the PSCell within the SCG, duration information corresponding to the state of other SCells other than the PSCell within the SCG, network element information indicating activation or deactivation of the SCG, and includes at least one of the information on whether the network-side configuration permits the terminal's application for activation or deactivation of the SCG.

[0074] In this embodiment, the first information can also be transmitted between network devices. For example, in the handover process, the source base station transmits the first information to the target base station, so that the target base station can determine whether to configure dual connectivity for the terminal, whether to activate the SCG, etc. in subsequent processes. Here, by way of example, both the first network device and the second network device may be access network devices such as base stations.

[0075] In some alternative embodiments, the step of the first network device transmitting the first information related to the activation or deactivation of the terminal's PSCell or SCG to the second network device includes the step of the first network device transmitting a handover request message to the second network device, and the handover request message includes the first information.

[0076] In some alternative embodiments, the first information may be collected by the first network device (such as a base station) itself without the need for the terminal to report it to the first network device. This is because both the activation and deactivation of the SCG are configured by the first network device (such as a base station), so the first network device (such as a base station) can know the first information.

[0077] Based on the above embodiments, the embodiments of the present application further provide a communication device applied to a terminal.
