Description

Communication method, device, equipment, storage medium, chip, product and program Technical Field

[0001] The embodiments of the present application relate to the field of mobile communication technologies, and specifically to a communication method, apparatus, device, storage medium, chip, product, and program. Background Art

[0002] With the development and changes in mobile communications, the fifth generation mobile communication (5G) network has higher requirements for latency, especially ultra-reliable and low latency communications (URLLC), which need to achieve end-to-end latency of ten milliseconds to support emerging business applications such as autonomous driving, industrial Internet, augmented reality, and virtual reality. On the other hand, 5G networks use higher frequency bands, and 5G cells have a smaller radius and more cells than 4G (the fourth generation mobile communication technology) cells. Therefore, HO (cell switching) caused by UE movement in a connected state will be more frequent, bringing unprecedented challenges to the operation and maintenance of 5G networks. To overcome the end-to-end handover latency problem and better adapt to dense networking scenarios, the Conditional Handover (CHO) mechanism was proposed in the 3GPP 4G / 5G system.

[0003] However, the related art does not pay attention to the switching in the dual connectivity (DC) scenario.

[0055] To facilitate understanding of the technical solutions of the embodiments of the present application, the relevant technologies of the embodiments of the present application are described below. The following relevant technologies can be arbitrarily combined with the technical solutions of the embodiments of the present application as optional solutions, and they all fall within the protection scope of the embodiments of the present application.

[0056] Conditional Handover (CHO) is a technology designed to improve handover robustness during standardization. Unlike traditional base station-triggered instantaneous handovers, the core concept of conditional handover is to pre-configure the target cell's handover command to the UE when the source cell's link quality is good, and to associate a handover execution condition with the handover command. When the configured handover execution condition is met, the UE can spontaneously initiate a handover access to the target cell based on the configuration in the handover command.

[0057] FIG2 is a schematic diagram of a CHO process provided by an embodiment of the present application. As shown in FIG2 , the conditional switching process is divided into three stages:

[0058] Handover Preparation: After receiving a measurement report from the UE, the source gNB initiates a conditional handover preparation procedure and sends a handover request message to the target gNB. If the target gNB receives the handover request, it responds with a target cell configuration and sends it to the source gNB. When forwarding the target cell configuration, the source gNB also configures a set of handover execution conditions for the UE. These handover execution conditions can optionally reuse the A3 and A5 events in the Radio Resource Management (RRM) measurement architecture. When these events are met, the UE initiates the handover access procedure to the target cell.

[0059] Handover execution phase: After receiving the candidate cell configuration, the UE needs to continuously evaluate whether the measurement results of the candidate cell meet the handover execution conditions. If the conditions are met, the UE disconnects from the source cell, establishes synchronization with the target cell that meets the conditions, and then initiates a random access process. When the random access process is complete, it reports a handover completion message to the target base station.

[0060] Switching completion phase: The switching completion phase is similar to the traditional switching process, including the path replacement process.

[0061] CHO switching methods include:

[0062] Switch preparation:

[0063] S201. Mobility control information provided by the AMF. In this step, the UE context in the source gNB contains information about roaming and access restrictions, which is provided at connection establishment or at the last Timing Advance (TA) update.

[0064] S202, Measurement Control and Reporting. In this step, the source gNB configures the UE measurement process, and the UE reports according to the measurement configuration.

[0065] S203, CHO decision: In this step, the source gNB decides to use CHO.

[0066] S204. The source gNB sends a handover request to the target gNB, and the source gNB sends a handover request to other potential target gNB(s).

[0067] In this step, the source gNB requests CHO for one or more candidate cells belonging to one or more candidate gNBs; a CHO request message is sent for each candidate cell.

[0068] S205. The target gNB performs admission control, and other potential target gNB(s) perform admission control.

[0069] In this step, admission control may be performed by the target gNB; if slice information is sent to the target gNB, slice-aware admission control shall be performed; if a Protocol Data Unit (PDU) session is associated with an unsupported slice, the target gNB shall reject such a PDU session.

[0070] S206. The target gNB sends a handover request acknowledgement to the source gNB, and the other potential target gNB(s) send a handover request acknowledgement to the source gNB.

[0071] In this step, the candidate gNB sends a CHO response (i.e., handover request confirmation) to the source gNB, including the configuration of the CHO candidate cell.

[0072] S207. The source gNB sends a Radio Resource Control (RRC) reconfiguration (RRCReconfiguration) to the UE.

[0073] In this step, the source gNB sends an RRC reconfiguration message to the UE, which includes the configuration of the CHO candidate cells and the CHO execution conditions.

[0074] S208. The UE sends an RRC reconfiguration completion message to the source gNB.

[0075] Switch execution:

[0076] If early data forwarding is applied, the source gNB sends an EARLY STATUS TRANSFER message.

[0077] The UE evaluates the CHO conditions, and if the CHO conditions are met, leaves the old cell and synchronizes to the new cell.

[0078] User data sent by the UPF(s) is forwarded by the source gNB to other potential target gNB(s).

[0079] S209: CHO handover completion.

[0080] After receiving the CHO configuration, the UE maintains its connection to the source gNB and begins evaluating the CHO execution conditions for candidate cells. If at least one CHO candidate cell meets the corresponding CHO execution conditions, the UE detaches from the source gNB, applies the stored configuration for the selected candidate cell, synchronizes to the candidate cell, and sends an RRC Reconfiguration Complete message to the target gNB. The UE releases the stored CHO configuration after successfully completing the RRC handover procedure.

[0081] Switching completed:

[0082] S209a. The target gNB sends a handover success message to the source gNB.

[0083] S209b. The source gNB sends a SN STATUS TRANSFER message to the target gNB.

[0084] In S209a and S209b, the target gNB sends a Handover Success message to the source gNB, notifying the UE that it has successfully accessed the target cell. In response, the source gNB sends an SN STATUS TRANSFER message according to the intra-AMF / UPF handover principle.

[0085] After the source gNB receives the handover success message, it can start delayed data forwarding.

[0086] User data sent by the UPF(s) is forwarded to the target gNB via the source gNB.

[0087] S209c. The source gNB sends a handover cancel to the target gNB and other potential target gNB(s).

[0088] The source gNB sends a Handover Delete message to other signaling connections or other candidate target gNBs (if any) to cancel the UE’s CHO.

[0089] When the terminal device determines the target primary cell (PCell) according to the CHO, the link quality of the primary secondary cell (PSCell) associated with the Pcell may be poor.

[0090] The CHO introduced in the related art does not support candidate cell configuration (such as secondary cell group (SCG) configuration). In order to support CHO in the multi-radio access technology dual connectivity (Multi-RAT Dual Connectivity, MR-DC) scenario, the signaling design between the Xn interface can be further enhanced to support the inclusion of an SCG configuration in the CHO candidate cell configuration. A potential problem with this configuration method is that when the UE determines the target primary cell (PCell) based on the execution conditions, the link quality of the primary and secondary cell (PSCell) associated with the PCell may become insufficient, or it may not be a suitable PSCell, which will cause the UE to fail to successfully access the PSCell.

[0091] Therefore, since the relevant technology does not support the inclusion of CPA / CPC in CHO, and in order to further optimize the impact of mobility on the throughput of dual connectivity (DC) scenarios, CHO+CPA / CPC will be discussed. That is, a CHO candidate cell configuration can include a primary cell group MCG configuration and at least one secondary cell group SCG configuration for conditional primary and secondary cell addition / change (CPA / CPC), thereby reducing the probability of secondary cell group SCG failure (SCG failure). Optionally, CPA / CPC is also called CPAC.

[0092] To facilitate understanding of the technical solutions of the embodiments of the present application, the technical solutions of the present application are described in detail below through specific embodiments. The above related technologies can be combined arbitrarily with the technical solutions of the embodiments of the present application as optional solutions, and all of them fall within the scope of protection of the embodiments of the present application. The embodiments of the present application include at least part of the following contents.

[0093] The following section of this application discusses how to support CHO+CPA / CPC, for example, how to configure CHO+CPA / CPC and how to determine the evaluation order of CHO and CPA / CPC.

[0094] FIG3 is a flow chart of a communication method provided in an embodiment of the present application. As shown in FIG3 , the communication method includes:

[0104] Optionally, at least one CHO candidate cell may have a correspondence / association relationship with at least one CPA / CPC candidate cell. Exemplarily, the CHO candidate cell may have a one-to-one correspondence / association relationship with the CPA / CPC candidate cell, or a many-to-one correspondence / association relationship, or a one-to-many correspondence / association relationship.

[0105] Optionally, the first configuration information may further include or indicate the correspondence or association between each CHO candidate cell and the corresponding CPA / CPC candidate cell. For example, CHO candidate cell 1 corresponds to CPA / CPC candidate cell 1, then the first configuration information may include or indicate the correspondence between CHO candidate cell 1 and CPA / CPC candidate cell 1. For another example, CHO candidate cell 1 corresponds to CPA / CPC candidate cell 1 and CPA / CPC candidate cell 2, then the first configuration information may include or indicate the correspondence between CHO candidate cell 1, CPA / CPC candidate cell 1 and CPA / CPC candidate cell 2. For another example, CHO candidate cell 1 and CHO candidate cell 2 both correspond to CPA / CPC candidate cell 1, then the first configuration information may include or indicate the correspondence between CHO candidate cell 1 and CHO candidate cell 2 and CPA / CPC candidate cell 1.

[0106] Optionally, the first execution condition and / or the second execution condition may correspond to the measurement result of the downlink reference signal. Exemplarily, any first execution condition may include: the measurement result of the downlink reference signal of one or more CHO candidate cells (corresponding to candidate PCell) is greater than or equal to the first threshold, and / or, the measurement result of the downlink reference signal of the current CHO cell (corresponding to the current PCell) is less than or equal to the second threshold. Exemplarily, any second execution condition may include: the measurement result of the downlink reference signal of one or more CPA / CPC candidate cells (corresponding to candidate PSCell) is greater than or equal to the third threshold, and / or, the measurement result of the downlink reference signal of the current CPA / CPC cell (corresponding to the current PSCell) is less than or equal to the fourth threshold.

[0107] Optionally, the downlink reference signal may include at least one of the following: a synchronization signal block (SSB) and a channel state information reference signal (CSI-RS). The SSB may also be referred to as a synchronization signal / physical broadcast channel block (SS / PBCH Block).

[0108] Optionally, the measurement parameters corresponding to the measurement result may include at least one of the following: reference signal received power (RSRP), reference signal received quality (RSRQ), received signal strength indicator (RSSI), signal to interference plus noise ratio (SINR), received signal code power (RSCP), and signal to noise ratio (SNR).

[0109] Optionally, any first execution condition may correspond to one or more thresholds. For example, any first execution condition may correspond to an RSRP threshold and / or an RSRQ threshold. Optionally, any second execution condition may correspond to one or more thresholds. For example, any second execution condition may correspond to an RSRP threshold and / or an RSRQ threshold.

[0111] The A1 event corresponds to the RSRP value of the serving cell being higher than the absolute threshold. The A1 event can be used to disable measurements between certain cells.

[0112] An A2 event corresponds to the RSRP value of the serving cell falling below the absolute threshold. This event can be used to enable inter-cell measurements, as handovers and other operations may occur after this event occurs.

[0113] Event A3 corresponds to the RSRP value of the neighboring cell being higher than the RSRP value of the serving cell. The occurrence of event A3 can be used to determine whether the UE should be handed over to the neighboring cell.

[0114] Event A4 corresponds to: the RSRP value of the neighboring cell is higher than the absolute threshold.

[0115] The A5 event corresponds to: the RSRP value of the serving cell is lower than the absolute threshold 1 and the RSRP value of the neighboring cell is higher than the absolute threshold 2. The A5 event can also be used to support handover.

[0116] The B1 event corresponds to: the RSRP value of the heterogeneous neighboring cell is higher than the absolute threshold. The B1 event indicates that the heterogeneous neighboring cell quality is higher than a certain threshold. When this condition is met and the event is reported, the source base station initiates the heterogeneous system handover request.

[0117] The B2 event corresponds to: the RSRP value of the serving cell is lower than the absolute threshold 1 and the RSRP value of the heterogeneous system neighboring cell is higher than the absolute threshold 2. The B2 event indicates that the quality of the serving cell is lower than a certain threshold and the quality of the heterogeneous system neighboring cell is higher than a certain threshold.

[0308] Optionally, the terminal device may evaluate the first execution condition and the second execution condition simultaneously. When the first execution condition and the second execution condition are simultaneously satisfied, the terminal device executes CHO+CPA / CPC.

[0310] Optionally, when the first execution condition is met, the second execution condition is still met, and the CPA / CPC candidate cell that meets the second execution condition is associated with the target PCell / MCG, the terminal device performs CHO and CPA / CPC simultaneously;

[0311] When the second execution condition is met, the first execution condition is still met, and the PCell / MCG meeting the first execution condition is associated with the CPA / CPC candidate cell meeting the second execution condition, the terminal device performs CHO and CPA / CPC simultaneously;

[0312] Otherwise, the terminal device continues to evaluate the first execution condition and the second execution condition.

[0313] In the communication method provided in this application, the evaluation order and execution order of the CHO+CPA / CPC process are clarified.

[0314] Optionally, in some embodiments, the execution order of CHO and CPA / CPC may include: executing CPA / CPC after CHO is completed, or executing CPA / CPC during the execution of CHO.
