Detailed Description
Example embodiments will now be described more fully hereinafter with reference to the accompanying drawings.
It should be noted that the exemplary embodiments can be implemented in various forms and should not be construed as limited to the examples set forth herein.
The 3GPP introduces a double connection technology (Multi-Radio Dual Connectivity, MR-DC) in the R12 stage, so that the base stations can be shunted through an X2/Xn interface, and the coverage capacity and the spectrum utilization rate of the network are improved. The technology is also widely applied to 4G and 5G coexistence scenes, and MR-DC becomes one of key technologies under a 5G multi-network fusion architecture.
With the development of millimeter wave and other technologies, the MR-DC architecture is widely applied to the actual deployment scene of B5G to 6G wireless networks, and is used for improving the coverage and system capacity of the networks, ensuring the service quality of users and improving the utilization rate of the network spectrum.
By dual connectivity, it is meant that one terminal can be connected to two base stations simultaneously. As shown in fig. 1, a terminal 101 is connected to a first base station 102 and a second base station 103, respectively, and the first base station 102 and the second base station 103 are connected to a core network 104, respectively. The first base station 102 and the second base station 103 may be the same type of base station or different types of base stations, and are called MR-DC or NR-DC.
As one example, the first base station 102 and the second base station 103 may all be 5G base stations.
As another example, the first base station 102 may be a 4G base station and the second base station 103 may be a 5G base station.
In some embodiments, the first base station 102 may be a Master Node (MN); the second base station 102 may be a network Node (SN).
When the terminal 101 is to surf the internet, it first accesses the main node, and then adds the auxiliary node as required. The master node, also called an "anchor point", is responsible for interacting with the control plane of the core network.
As shown in fig. 2, the internal part can also support multiple carriers for carrier aggregation, whether the primary node or the secondary node.
For the master node, the plurality of cells inside the first base station 202 are referred to as a master cell group (Master Cell Group, MCG);
Correspondingly, the plurality of cells within the secondary node second base station 203 is referred to as secondary cell group (Secondary Cell Group, SCG).
For MCG, similar to normal carrier aggregation, the primary cell is also called Pcell (Primary cell) and the secondary cell is also called Scell (Secondary cell).
For SCG, the primary cell is called PSCell (Primary Secondary Cell ), while the remaining common secondary cells are still called secondary cell scells.
The 3GPP starts from R16 to study the NR system MRO (Mobility Robustness Optimisation, mobile robustness optimization) solution. The MRO scheme aims at avoiding unnecessary switching, improving the quasi-determination and robustness of switching and optimizing the network mobility performance.
The inventors have found that solutions have been designed in the relevant MRO solutions for the cell Handover failure (Handover) and PSCell change failure scenarios, and optimized for the "near Radio Link Failure (RLF)" scenario that occurs in the Handover success scenario. However, in the related solution, the network cannot obtain the related information about the near failure scenario in the primary and secondary cell Change (PSCell Change) process (for example, the T310 timer has been run to 80% or even more than 90%), so that the optimization cannot be performed for such situations, which may cause the terminal to generate more serious radio link failure or SCG connection failure.
It should be noted that the embodiments of the present disclosure are applicable to MRDC scenarios, which may include ENDC, NRDC, NGEN-DC.
Embodiments of the present disclosure are directed to a scenario in which a PSCell changes. The scene in which the PSCell changes may include: traditional PSCell addition, conditional PSCell addition, traditional PSCell change, conditional PSCell change, wherein the PSCell change scene is further divided into MN-initiated PSCell change and SN-initiated PSCell change;
the PSCell change scene can be further divided into intra-SN PSCell change and inter-SN PSCell change.
The definition of the T310 timer in the relevant standard is as follows:
upon the bottom layer receiving N310 consecutive "out of sync" indications for a PSCell (NR) cell, the UE starts a timer T310. Assuming the UE receives an N311 In-Sync indication before the timer expires, the T310 timer will stop. Otherwise, the timer times out the UE triggers RLF (radio link failure). It can be seen that the T310 timer may reflect the connection status of the terminal and the SCG, and if the terminal side T310 timer has timed out (e.g. has run to 90% or more of the preset value), this indicates that the SCG Failure has been triggered soon at this time, i.e. the "near Failure scenario" described in this patent.
Based on the above, the embodiment of the disclosure provides a primary and secondary cell Change optimization scheme, so that a network can timely acquire necessary information recorded on a terminal side in a PSCell Change near failure scene, analyze reasons potentially causing radio link failure based on the information, and further optimize relevant configuration parameters of a PSCell Change flow, thereby improving the success rate of the PSCell Change and improving the robustness of the network.
It should be noted that, in the embodiments of the present disclosure, the terminal includes, but is not limited to, a mobile phone, a tablet computer, a notebook computer, an in-vehicle communication device, an unmanned aerial vehicle, a communication module on an unmanned aerial vehicle, a remote control aircraft, an aircraft, a mini-plane, a vehicle, an RSU, a wireless sensor, an internet of things terminal, an RFID terminal, an NB-IOT terminal, an MTC (Machine Type Communication ) terminal, an eMTC (enhanced MTC) terminal, a data card, an internet card, an in-vehicle communication device, a low-cost mobile phone, a low-cost tablet computer, and other wireless communication devices.
In the embodiment of the disclosure, the "base stations" such as the first base station and the second base station include, but are not limited to, macro cellular base stations, micro cellular base stations, small cellular base stations, home base stations, relay base stations, enbs, gnbs, TRP (Transmitter Receiver Point, transmitting and receiving nodes), GNSS, relay satellites, satellite base stations, air base stations, RSUs (Road Side units), unmanned aerial vehicles, and test equipment, such as transceiver devices or signaling testers for simulating the functions of the base station parts.
The present exemplary embodiment will be described in detail below with reference to the accompanying drawings and examples.
Fig. 3 shows a flowchart of a primary and secondary cell change optimization method in an embodiment of the present disclosure, and as shown in fig. 3, the primary and secondary cell change optimization method provided in the embodiment of the present disclosure includes the following steps:
s302, a first network node sends a first signaling to a terminal, wherein the first signaling indicates the terminal to report a successful report of the primary and secondary cell change.
Here, the first network node may be a base station connected to the terminal.
As an example, in a dual connectivity technique, the first network node may be a network master node.
In some embodiments, the primary and secondary cell change success report may contain at least one of the following information:
source primary and secondary cell identity (Source PSCell ID), latest measurement report of Source primary and secondary cells, target primary and secondary cell identity (Target PSCell ID), latest measurement report of Target primary and secondary cells, candidate primary and secondary cell identity (Candidate PSCell ID), latest measurement report of candidate primary and secondary cells, latest measurement report of surrounding cells, terminal position information, CPC (conditional PScell change) indication information, CPA (Conditional PSCell Addition) indication information, time interval between successful CPC configuration and CPC trigger execution (timesinceconconfiguration) received by the terminal, time interval between successful CPA configuration and CPA trigger execution (timesinceconconfiguration) received by the terminal, and user plane data terminal time (updatainter time);
The CPC indication information indicates that the primary and secondary cell change success report corresponds to a conditional primary and secondary cell change flow; CPA indication information indicates that the primary and secondary cell change success report corresponds to a conditional primary and secondary cell addition flow.
S304, the terminal reports a successful report of the primary and secondary cell change to the first network node through the second signaling, and the successful report of the primary and secondary cell change is used for optimizing the configuration of the primary and secondary cell change.
In some embodiments, the first network node may perform an initial analysis of the primary and secondary cell change success report, identifying a source node of a primary and secondary cell change procedure that triggered the primary and secondary cell change success report.
Here, the source node may be the first network node or the second network node.
After receiving a report reported by a terminal, a first network node firstly performs initial analysis, identifies a source node triggering a primary and secondary cell Change (PSCell Change) process of a corresponding report, and if the source node is triggered by the first network node, the first network node further performs deep root cause analysis, identifies a cause which possibly induces an adjacent failure event to occur, optimizes network configuration parameters and improves network robustness; if the first network node performs preliminary analysis and then recognizes that the trigger node corresponding to the PSCell Change procedure is the second network node, the first network node forwards the report to the second network node through the third signaling, and the second network node performs root cause analysis and optimal configuration.
That is, when the source node is the second network node, the first network node also forwards the primary and secondary cell change success report to the second network node through the third signaling.
In some embodiments, the first network node may be a network master node MN and the second network node may be a network slave node SN.
In the above embodiment, the source node optimizes the primary and secondary cell change configuration based on the primary and secondary cell change success report.
In some embodiments, the primary and secondary cell change success report also carries information for terminal measurements and records added by the secondary node. That is, the embodiment of the present disclosure is also applicable to secondary node Addition, that is, SCG Addition/PSCell Addition flow, where conventional primary and secondary cell Addition and conditional primary and secondary cell Addition are both applicable, and it may be understood that secondary node Addition (that is, PSCell Addition) is a special case of PSCell Change, where the foregoing primary and secondary cell Change success report may carry some information measured and recorded by the terminal in the secondary node Addition process, where the terminal reports as needed based on the indication of the first network node and according to the type of flow executed by the terminal. In the above embodiment, optimizing the primary and secondary cell change configuration may include at least one of the following adjustments:
Adjusting the condition configuration triggering the addition or change of the primary and secondary cells, adjusting the event configuration triggering the addition or change of the primary and secondary cells, and adjusting the threshold value of the triggering event.
That is, conditions and/or event configurations that trigger PSCell Change, thresholds for trigger events that are appropriately turned up or down, etc. may be appropriately adjusted.
The embodiment of the disclosure enhances the reporting information of the UE and the information transfer flow among the nodes, so that the terminal records and stores related information and reports the network under the condition that the primary and secondary cells are changed and fail nearby, thereby helping the network to analyze the improper position of configuration and adjust in time, and optimizing the configuration of the system.
It should be noted that, in the embodiment of the present disclosure, the first signaling and the second signaling may be RRC signaling, and the third signaling may be Xn/X2 interface signaling.
In one example, the first signaling is RRC signaling (NW UE), which may be ueinfo request signaling.
In one example, the second signaling is RRC signaling (UE NW), which may be ueinfo information response signaling.
In one example, the third signaling is at least one of Access and mobility indication signaling, SN/SgNB Modification Request signaling, and newly added Xn/X2 signaling.
If the source node is a separate architecture, a primary and secondary cell change success report is transmitted between the centralized entity CU and the separate entity DU of the source node through the Access and mobility indication signaling of the F1 interface.
That is, if the first network node or the second network node is a CU-DU split architecture, the PSCell Change Report also needs to be delivered over the F1 interface, in one embodiment, the report is signaled using Access and mobility indication of the F1 interface;
in some embodiments, the primary and secondary cell change success report may be included in other UE reporting information, such as a handover success report (Successful Handover Report).
In the presently disclosed embodiments, the terms "first," "second," and "third" are used for descriptive purposes only and are not to be construed as indicating or implying relative importance.
The term "and/or" in this disclosure is merely one association relationship describing the associated object, and indicates that three relationships may exist, for example, a and/or B may indicate: a exists alone, A and B exist together, and B exists alone. In addition, the character "/" herein generally indicates that the front and rear associated objects are an "or" relationship.
The following describes the schemes of the embodiments of the present disclosure in detail in conjunction with specific application scenarios.
