Detailed Description

The technical solutions in the embodiments of the present application will be described below with reference to the accompanying drawings.

By way of example, fig. 1A illustrates a wireless communication system to which the present application relates. The wireless communication system 100 may operate in a high frequency band, and may be a fifth generation mobile communication (5 g) system, a New Radio (NR) system, a Machine to Machine (M2M) system, etc. in the future. As shown, the wireless communication system 100 may include: one or more network devices 101, one or more terminals 103, and a core network device 105. Wherein: the network device 101 may be a base station, which may be configured to communicate with one or more terminals and may also be configured to communicate with one or more base stations having partial terminal functions (e.g., communication between a macro base station and a micro base station, such as an access point). The Base Station may be a Base Transceiver Station (BTS) in a Time Division Synchronous Code Division Multiple Access (TD-SCDMA) system, or an evolved Node B (eNB) in a Long Term Evolution (LTE) system, or a Base Station gNB in a 5G system or an NR system. In addition, the base station may also be an Access Point (AP), a transmission node (Trans TRP), a Central Unit (CU), or other network entities, and may include some or all of the functions of the above network entities. The core network device 105 includes a device on the core network side, such as a Serving GateWay (SGW). The terminals 103 may be distributed throughout the wireless communication system 100 and may be stationary or mobile. In some embodiments of the present application, the terminal 103 may be a mobile device (e.g., a smart phone), a mobile station (mobile station), a mobile unit (mobile unit), an M2M terminal, a wireless unit, a remote unit, a User agent, a User Equipment (UE) mobile client, and so on.

It should be noted that the wireless communication system 100 shown in fig. 1A is only for more clearly illustrating the technical solution of the present application, and does not constitute a limitation to the present application, and as a person having ordinary skill in the art knows, the technical solution provided in the present application is also applicable to similar technical problems as the network architecture evolves and new service scenarios emerge.

The related art to which the present application relates is described below.

Currently, as shown in fig. 1B, the main process of the terminal performing cell handover includes: handover preparation, handover execution, and handover completion. The switching preparation means that the source base station configures the terminal to perform measurement reporting, and sends a switching request to the target base station based on the reporting result of the terminal. When the target base station agrees to the handover request, a Radio Resource Control (RRC) message (e.g., mobility Control information) including a Random Access Channel (RACH) Resource, a cell Radio network temporary identifier (C-RNTI), a target base station security algorithm, a system message of the target base station, and the like is configured for the terminal. The switching execution comprises that the source base station transmits the mobile control information to the terminal, and the terminal initiates a random access flow to the target base station after receiving the switching command. Meanwhile, the source base station sends a sequence Number STATUS TRANSFER (SN STATUS TRANSFER) to the target base station, and is configured to inform the target base station of a Packet Data Convergence Protocol (PDCP) sequence Number (Serial Number, SN) receiving STATUS and a downlink PDCP SN sending STATUS. The switching completion includes that after the terminal is successfully accessed to the target base station (random access is successful), the target base station sends a PATH switching request (PATH SWITCH REQ) terminal ST to request a Mobility Management Entity (MME) to SWITCH a downlink PATH, and after the PATH switching (PATH SWITCH) is completed, the target base station instructs the source base station to release the terminal context, and the switching is completed.

For some special scenarios, such as high-speed movement or high-frequency conditions, frequent switching is required. Conditional handover (conditional handover) can avoid the problem that the time for handover preparation is too long, which causes the time for the terminal to handover to be late, and as shown in fig. 1C, a handover command HO command can be configured in advance for the terminal. On the other hand, for a high-speed rail scene, the operation track of the terminal is specific, so the base station can allocate the target base station to the terminal in advance, and the handover command HO command includes a condition for triggering the terminal to perform handover, and when the allocated condition is satisfied, the terminal initiates an access request to the target base station. Currently, 3gpp ran2#104 conferences already agree to a conditional handover and support the configuration of multiple target cells in the HO command of the conditional handover. And the terminal judges which target cell is accessed based on the configured condition.

Dual-Connectivity (DC) is an important technology introduced by the 3GPP Release-12 Release. By the dual connectivity technology, the LTE macro station and the LTE small station can utilize the existing non-ideal backhaul (non-ideal backhaul) X2 interface to implement carrier aggregation, thereby providing a higher rate for users. The terminal supporting double connection can be connected with two LTE base stations simultaneously, and the throughput of a single user is increased. In the deployment process of the 5G network, the 5G cell can be used as a macro coverage independent network, and can also be used as a small station to perform coverage and capacity enhancement on the existing LTE network. 3GPP Release-14 defines the dual connection technology of LTE and 5G on the basis of the LTE dual connection technology. The LTE/5G dual connection is a key technology for realizing LTE and 5G fusion networking and flexible deployment scene of operators. The rapid deployment can be realized based on the existing LTE core network in the early 5G period, and the comprehensive network coverage can be realized through the combined networking of the LTE and the 5G in the later period, so that the wireless resource utilization rate of the whole network system is improved, the system switching time delay is reduced, and the user performance and the system performance are improved.

At present, the configuration of the terminal in the wireless communication system is real-time, and when the link condition is not good, the terminal may fail to receive the configuration information in time.

In view of the above problems, the embodiments of the present application propose the following embodiments, which are described in detail below with reference to the accompanying drawings.

Referring to fig. 2, fig. 2 is a schematic diagram of a configuration method of conditional triggering according to an embodiment of the present application, applied to the exemplary communication system, where the method includes:

in the 201 part, the terminal detects the target state information and acquires the detection result;

at part 202, when the detection result meets a trigger condition, the terminal executes a pre-stored configuration.

It can be seen that, in the embodiment of the present application, a terminal may detect target state information to obtain a detection result, and execute a pre-stored configuration when the detection result meets a trigger condition, so that the terminal may pre-store configurations and corresponding trigger conditions in various service scenarios, and determine whether to autonomously execute the configuration by detection and condition judgment, for example, in a handover scenario, the current configuration may be updated according to the current channel quality, the environment and the location of the terminal, or other auxiliary information, so that the configuration information is more matched with the current service scenario, and the whole process does not need to interact with a network device in real time, thereby avoiding that the configuration execution process cannot be completed due to untimely receiving of the configuration, such as poor link conditions, and the like, and facilitating to increase flexibility and reliability of terminal handover configuration.

In one possible example, the configuration is implemented by a radio resource control, RRC, connection reconfiguration message, or by a system message.

The radio resource control configuration message includes the requirement information of accessing the target cell, and the requirement information at least includes a cell identifier (cell ID), a new cell radio network temporary identifier, and a target base station security algorithm identifier.

In one possible example, the target state information is state information constrained by the trigger condition; the target state information includes at least one of: channel quality, RRC state, scene where the terminal is located, and time period used by the terminal.

The channel Quality may include Reference Signal Receiving Power (RSRP), reference Signal Receiving Quality (RSRQ), or a channel condition of layer 1 (L1). The RRC states may include an RRC connected state, an RRC idle state, and an RRX inactive state. The scene of the terminal comprises a mobile scene, a non-mobile scene, a position scene, a large venue dense connection scene (judged by the geographic position of the terminal) and the like. The period used by the terminal may include, for example, a core work period, a leisure work period, or an evening period, and may specifically be agreed in advance.

In one possible example, the scenario in which the terminal is located includes a mobility scenario; the triggering condition is issued in a Radio Resource Control (RRC) connection reconfiguration message, and the triggering condition is configured by a source base station of the terminal.

In this possible example, the configuration is for handover of the terminal to a target cell, and the trigger condition is associated with the configuration of the target cell; the trigger condition includes an access condition of one or more cells.

In this possible example, the trigger condition comprises an access condition of one cell; the access condition comprises the access condition of the cell as a main cell, or comprises the access condition of the cell as a secondary cell, wherein the main cell comprises the cells under a main cell group MCG, and the secondary cell comprises the cells under a secondary cell group SCG.

In this possible example, the trigger condition comprises an access condition of a plurality of cells; the combination relationship of the plurality of cells comprises a main cell and a main cell, or the main cell and an auxiliary cell, or the auxiliary cell and an auxiliary cell.

In one possible example, the configuration is for handover of the terminal to a target cell, the trigger condition is associated with the configuration of the target cell; the trigger condition comprises an access condition of one or more cell groups.

In this possible example, the trigger condition comprises a first access condition of a first cell group, the first access condition comprises an access condition of one or more cells in the first cell group, and the combined relationship of the plurality of cells comprises a primary cell and a secondary cell, or a secondary cell and a secondary cell.

In one possible example, the configuration is for the terminal to release a secondary node; the trigger condition comprises a condition to release the secondary node.

In one possible example, the scenario in which the terminal is located includes a non-mobility scenario; the configuration is used for the terminal to configure a Discontinuous Reception (DRX) cycle.

In one possible example, the scene in which the terminal is located includes a location scene; the configuration is used for the terminal to configure the wireless resources of the location scenario.

In one possible example, the configuration is configured by a target base station of the terminal and forwarded to the terminal through a source base station of the terminal, or the configuration is configured by the source base station and issued to the terminal.

In one possible example, the trigger condition includes a first condition and a second condition, and a dependency exists between the first condition and the second condition, the dependency including a priority order, or a strong constraint relationship.

Wherein, the strong constraint relationship may be, for example: condition 1 is a requirement of condition 2, etc., and is not limited to the only condition.

In specific implementation, if the terminal determines that the detection result meets the first condition, the terminal continues to determine whether the detection result meets the second condition.

The following is further described with reference to specific scenario examples.

Referring to fig. 3A, fig. 3A is a method for conditional triggered cell access according to an embodiment of the present application, which is applied to the exemplary communication system, and the method includes:

in part 3a01, the terminal receives a handover command, where the handover command configures multiple target base stations, and each target base station configures trigger conditions for a primary cell and a secondary cell during carrier aggregation.

In part 3a02, the terminal performs channel quality and cell number detection on the primary cell and the secondary cell of each target base station to obtain a detection result.

In the part 3a03, if the detection result is that the channel quality of the primary cell of the target base station 1 meets the corresponding trigger condition, the terminal accesses the target base station 1.

In the part 3a04, if the detection result is that both the channel quality of the primary cell of the target base station 1 and the channel quality of the secondary cell of the target base station 2 satisfy the configured conditions, at this time, if the number of secondary cells of the target base station 1 that satisfy the corresponding trigger conditions is greater than the number of secondary cells of the target base station 2 that satisfy the corresponding trigger conditions, the terminal preferentially accesses the target base station 1.

In the part 3a05, if the detection result is that the channel quality of the primary cell of the target base station 1 and the channel quality of the secondary cell of the target base station 2 both satisfy the corresponding trigger condition, and the number of the secondary cells of the target base station 1 satisfying the corresponding trigger condition is equal to the number of the secondary cells of the target base station 2 satisfying the corresponding trigger condition, the terminal compares the channel quality of the primary cell and the channel quality of the secondary cell of the target base station 1 and the target base station 2 in sequence, and selects the target base station with stronger channel quality for access.

Therefore, in this example, the terminal can autonomously perform access of the target base station through detection of the channel quality and the number of cells, so that link influence is avoided, and reliability of performing base station access by the terminal is improved.

Referring to fig. 3B, fig. 3B is a diagram of a conditional triggered dual connectivity configuration method according to an embodiment of the present application, applied to the exemplary communication system, where the method includes:

in part 3B01, the terminal receives a handover command issued by the network device in advance, where the handover command includes at least two target base stations, and a plurality of trigger conditions are configured for one target base station, for example, the following trigger conditions:

(1) The target base station 1/target base station 2 becomes a trigger condition of the MN. (2) The target base station 1/the target base station 2 becomes a trigger condition of the secondary node SN. (3) In dual connectivity, the target base station 1 serves as the master node MN, and the target base station 2 serves as the trigger condition of the SN (the conditions of the SN of different MNs may be different for the target base station 2).

In the part 3B02, the terminal carries out state detection to obtain a detection result;

in part 3B03, if only the target base station 1 satisfies the MN condition as a result of the detection, the terminal attempts to establish connection with the target base station 1 (handover to the target base station 1)

In part 3B04, if the detection result is that the target base station 1 (MN) and the target base station 2 (SN) simultaneously satisfy the condition, the UE switches to the dual connectivity mode.

In part 3B05, if the target base station 1 satisfies the SN condition as a result of the detection, the terminal adds the target base station 1 as an SN.

In the 3C02 part, the terminal detects the position information to obtain a detection result;

in part 3C03, if the detection result is that the current location of the terminal is in the first location area, the terminal performs the first radio resource configuration to adapt to the current location scenario.

In the 3D02 part, the terminal carries out channel quality detection to obtain a detection result;

and in the 3D03 part, if the detection result is that the channel quality of the SN is lower than the configured condition, the terminal releases the connection with the SN.

Referring to fig. 3E, fig. 3E is a diagram illustrating a method for configuring a DRX cycle triggered by a condition according to an embodiment of the present application, where the method is applied to the exemplary communication system, and the method includes:

in part 3E01, the terminal receives in advance the DRX configuration and the triggering condition of the period constraint within 24 hours issued by the base station once. For example, it may be: the DRX cycle configuration is short in the period of noon break or after work, because the UE frequently uses the mobile phone in the period, the DRX cycle/DRX-activity timer can be set to be long in the sleep time at night to achieve the power saving effect.

In the part 3E02, the terminal carries out time interval detection to obtain a detection result;

in part 3E03, if the detection result is a mid-day break period, the terminal performs configuration of a DRX cycle for the mid-day break period.

detecting target state information to obtain a detection result; and the pre-stored configuration is executed when the detection result meets the trigger condition.

It can be seen that, in the embodiment of the present application, a terminal may detect target state information to obtain a detection result, and execute a pre-stored configuration when the detection result meets a trigger condition, so that the terminal may pre-store configurations and corresponding trigger conditions in various service scenarios, and determine whether to autonomously execute the configuration through detection and condition judgment, for example, in a handover scenario, the current configuration may be updated according to the current channel quality, the environment and the location of the terminal, or other auxiliary information, so that the configuration information is more matched with the current service scenario, the whole process does not need to interact with a network device in real time, thereby avoiding that a configuration execution process cannot be completed due to untimely receiving of the configuration such as poor link conditions, and facilitating increasing flexibility and reliability of terminal handover configuration.
