Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention will be described in detail with reference to the accompanying drawings and specific embodiments.
Some concepts mentioned in the embodiments of the present invention are first explained as follows.
Double (one) connection
1. Several node definitions
eNB: a base station under a Long Term Evolution (LTE) system;
and g NB: a node of a User plane and a control plane that provide a New air interface (New Radio, NR) to a User Equipment (User Equipment, UE, also referred to as a terminal) is connected to the 5GC through an NG interface.
en-gNB: the nodes providing the NR user and control planes towards the UE act as secondary nodes in the EN-DC architecture.
ng-eNB: and the node which provides an Evolved UMTS terrestrial radio Access Network (E-UTRAN) user plane and a control plane for the UE is connected to the 5GC through an NG interface.
NG-C: a control plane interface between the NG-RAN and the 5 GC;
NG-U: a user plane interface between the NG-RAN and the 5 GC;
in a dual connectivity architecture, there may be one Master Node (MN) and one to more Secondary Nodes (SN).
2. Several architectural definitions
MR-DC: dual connectivity between E-UTRA and NR nodes. In MR-DC, one node acts as MN and the other as SN. The MN and the SN are connected through a network interface, wherein at least the MN is connected to a core network (5GC or EPC).
MR-DC contains several architectures:
2.1, E-UTRA-NR double junction (EN-DC): under this architecture, the UE connects to one eNB as the MN and one en-gNB as the SN. Where the eNB (i.e., MN) is connected to an all-IP packet core network (EPC) through an S1 interface and to an en-gbb (i.e., SN) through an X2 interface. The en-gNB may also be connected to the EPC through the S1-U interface, and the X2-U interface is connected to other en-gNB; as shown in particular in figure 1.
2.2 NG-RAN E-UTRA-NR Dual connectivity (NG EN-DC): under this architecture, the UE connects to one ng-eNB as the MN and to one gNB as the SN. Wherein the ng-eNB is connected to the 5GC and the gNB, wherein the nb-eNB possesses the protocol layer functionality of LTE, and the gNB is connected to the ng-eNB over an Xn interface.
2.3 NR-E-UTRA double ligation (NE-DC): in NE-DC, the UE is connected to one gNB as MN and one ng-eNB as SN. Where the gNB is connected to the 5GC and the ng-eNB is connected to the gNB through an Xn interface.
2.4, NR-DC: the UE is connected with two gNBs, wherein one gNB serves as a main node, and the other gNB serves as an auxiliary node;
in addition to the above architecture, LTE-DC (UE connected to two enbs, one as primary and the other as secondary) and LTE and WLAN Aggregation (LWA) are discussed in the standard.
IDLE (IDLE) state measurement
In order to recover Carrier Aggregation (CA) configuration quickly, idle mode (mode) related measurement and reporting mechanisms have been introduced in LTE systems. When the UE supports the IDLE state measurement capability of the CA and the IDLE state measurement configuration parameters of the network configuration are saved in the IDLE state, the IDLE state measurement may be performed, and when the relevant measurement result is saved, the measurement result is carried in the process that the UE enters the connected state. After receiving the measurement result, the network side can directly configure the activated CA cell for the UE.
(III) State transition
The NR system has 3 RRC states designed: an IDLE (RRC _ IDLE) state, a CONNECTED (RRC _ CONNECTED) state, and an INACTIVE (RRC _ INACTIVE) state. When RRC connection exists between the terminal and the network, the UE is in a connected state or an inactivated state, otherwise, the terminal is in an idle state. RRC state transition is shown in fig. 2. At one time, the terminal can only be in one RRC state.
The invention provides a measurement method of an auxiliary node, a measurement configuration method, a terminal and network equipment, aiming at the problems that in an NR system, when a UE is in a state transition to an RRC connection state, the measurement of the auxiliary node is not started, so that a terminal cannot rapidly acquire the measurement result of the auxiliary node and cannot ensure the reliability of network communication.
As shown in fig. 3, the method for measuring an auxiliary node according to an embodiment of the present invention is applied to a terminal, and includes:
step 31, starting measurement of the auxiliary node after the first preset condition is met;
it should be noted that the first preset condition includes one of the following information:
a11, triggering the state conversion process;
it should be noted that the state transition process includes: a Radio Resource Control (RRC) connection establishment procedure, an RRC connection recovery procedure, or an RRC connection reestablishment procedure.
A12, receiving an indication for starting auxiliary node measurement sent by network equipment in the state conversion process or after entering a connection state;
in this case, the network device triggers the terminal to start the measurement of the secondary node.
It should be further noted that, optionally, the first preset condition further includes at least one of the following manners:
a13, configuring Double Connection (DC) when the terminal is in the previous RRC connection state;
a14, the terminal stores the preset auxiliary node measurement configuration;
it should be noted that the preset secondary node measurement configuration refers to a dedicated secondary node measurement configuration. If the terminal obtains the measurement configuration information of the secondary node through the dedicated RRC message, it implicitly indicates that the network device can resume the configuration of the secondary node as soon as possible after expecting the network device to enter the RRC connected state, so that for the terminal, when receiving the measurement configuration information of the secondary node during the triggering state transition process or after entering the connected state, the measurement of the secondary node needs to be started.
A15, the terminal has the ability to communicate with the serving cell and perform target measurement simultaneously;
it should be noted that the target measurement includes: inter-frequency measurements and/or inter-technology measurements.
It should be further noted that the terminal needs to perform a measurement action on the secondary node according to the configuration information, and specifically, before the step 31, the method for measuring the secondary node in the embodiment of the present invention further includes:
acquiring configuration information measured by an auxiliary node;
it should be noted that the manner of acquiring the configuration information includes: protocol conventions or network device notifications.
Specifically, when the obtaining mode of the configuration information is notified by the network device, the obtaining of the configuration information measured by the secondary node includes:
acquiring configuration information measured by the auxiliary node through a preset message sent by the network equipment;
specifically, the preset message includes: RRC messages or broadcast messages.
Further, the configuration information includes at least one of the following information:
a21, duration of measurement of the secondary node;
a22, measuring the priority of the auxiliary node;
a23, measuring period or measuring interval of the auxiliary node;
it should be noted that the measurement period or measurement interval is usually set to be shorter than the period or interval of other measurements, so as to ensure that the measurement of the secondary node is performed and the measurement result is obtained as soon as possible.
A24, triggering event configuration information reported by a measurement result;
for example, the event configuration information is that the cell signal quality is greater than or equal to a preset threshold, that is, when the cell signal quality is greater than or equal to the preset threshold, reporting of the measurement result is triggered.
A25, configuration information of the auxiliary node measurement object;
the configuration information of the secondary node measurement object is used to indicate which contents are specifically measured when the measurement of the secondary node is performed.
It should be noted that, when the configuration information includes multiple items of the above information, the terminal may notify, through the network device, to acquire all the information; all information can also be acquired through protocol convention; the terminal can also obtain one part of information through the notification of the network equipment and obtain the other part of information through protocol convention. For example, when the configuration information includes: at a21, a22, a23 and a24, the a21, a22, a23 and a24 may all notify acquisition through network devices; or the a21, a22, a23 and a24 may all be acquired by agreement; alternatively, a21 and a22 acquire by agreement, a23 and a24 notify acquisition through the network device.
It should be further noted that, after starting the measurement of the secondary node, the terminal does not always perform measurement on the secondary node, and when a specific condition is satisfied, the terminal may stop the measurement on the secondary node, and the specific implementation manner is as follows: after the measurement of the auxiliary node is started, the measurement of the auxiliary node is stopped after a second preset condition is met.
It should be noted that the second preset condition includes one of the following information:
a31, completing state conversion;
it should be noted that the state transition completion includes: the terminal enters an RRC connection state or sends a state transition completion message; further, the state transition completion message includes: an RRC setup complete message, an RRC recovery complete message, or an RRC reestablishment complete message.
A32, measuring the overtime of a timer;
it should be noted that, in this case, before the terminal stops measuring the secondary node, the measurement timer should be started first, specifically, when the measurement timer starting condition is met, the measurement timer is started;
wherein the measurement timer start condition comprises one of the following information:
a321, the terminal receives configuration information of a measurement timer;
in this case, the configuration information of the measurement timer includes a timing duration, and the timing duration is a duration measured by the secondary node.
A322, the terminal starts the measurement of the auxiliary node.
In this case, the timing duration of the measurement timer is the duration measured by the secondary node or the timing duration of the measurement timer is a preset duration agreed by a protocol.
It should be further noted that, after the terminal starts the measurement of the secondary node, the measurement result of the secondary node may also be obtained by adopting a preset mode;
wherein the preset mode comprises at least one of the following modes:
a41, preferentially measuring the auxiliary nodes;
in this case, a specific implementation manner for obtaining the measurement result of the secondary node is as follows: determining whether the measurement of the auxiliary node needs to be performed preferentially according to the priority of the measurement of the auxiliary node; and when the auxiliary node is determined to be preferentially measured, preferentially measuring the auxiliary node to obtain the measurement result of the auxiliary node.
It should be noted that the priority measured by the secondary node may be agreed by a protocol or notified by the network device.
For example, the priority of the secondary node measurement may be determined based on the priority of the network device when configuring the measurement (i.e., the configuration information described above); for example, if the priority corresponding to the measurement configuration of the auxiliary node is 0, and the priority of the remaining RRM measurement is 2, the terminal preferentially performs the measurement of the auxiliary node; for example, the measurement configuration of the secondary node includes: measurement object 1, priority 1; measurement object 2, priority 2; and the priority of the other RRM measurement objects is 2, the terminal preferentially performs the measurement of the measurement object 1 in the secondary node, and then performs the measurement of the measurement object 2 in the secondary node and the measurement of the other RRM measurement objects.
A42, suspending a first Radio Resource Management (RRM) measurement or other RRM measurement except for the serving cell;
it should be noted that the first RRM measurement refers to a corresponding RRM measurement except for the secondary node.
A43, adopting a measuring period or a measuring interval;
it should be noted that, the measurement period or the measurement interval, that is, the measurement period or the measurement interval of the secondary node in the configuration information, is usually set to be shorter than the periods or intervals of other measurements, so that the measurement of the secondary node can be performed, and the measurement result can be obtained as soon as possible.
It should be further noted that, optionally, after the terminal obtains the measurement result of the secondary node, the measurement result may be reported to the network device, and the specific reporting mode includes at least one of the following modes:
a51, carrying the measurement result in the state transition completion message;
it should be noted that the state transition completion message includes: an RRC setup complete message, an RRC recovery complete message, or an RRC reestablishment complete message.
A52, reporting the measurement result to the network equipment after the measurement timer is overtime;
a53, reporting the measurement result based on the request of the network equipment;
a54, reporting the measurement result to the network device when the event configuration information triggering the reporting of the measurement result is satisfied.
Optionally, after the terminal obtains the measurement result of the secondary node, the terminal may further select a target secondary node to connect according to the measurement result.
The following specifically describes embodiments of the present invention in practical applications.
Situation one, triggering a state transfer process, starting SN measurement
As shown in fig. 4, the specific implementation process is as follows:
step S11, the terminal obtains the configuration information measured by the auxiliary node;

Optionally, the configuration information includes the following information (one or more):
b11, duration of secondary node measurement;

b14, triggering event configuration information reported by the measurement result, for example, the cell signal quality is greater than a certain threshold;
step S12, when the terminal triggers the state transition process, starting the measurement of the auxiliary node;
for example, the terminal triggers an RRC connection setup procedure, an RRC connection recovery procedure, or an RRC connection reestablishment procedure. At this time, the terminal starts the measurement of the auxiliary node according to the configuration information of the auxiliary node measurement obtained before.
Optionally, in addition to the condition of triggering the state transition process, the terminal further considers the following conditions to initiate measurement of the secondary node, including:
b21, the terminal is configured with DC in the last connection state;
at this time, it can be considered that after the terminal enters the RRC connected state, there is a need to recover the configuration of the secondary node as soon as possible, so that when the terminal triggers the state transition process, the measurement of the secondary node needs to be started;
b22, the terminal stores special SN measurement configuration;
that is, the terminal obtains the configuration information of the measurement of the secondary node through the dedicated RRC message in step S11, which implicitly indicates that the configuration of the secondary node can be resumed as soon as possible after the network side expects to enter the RRC connected state, so that the measurement of the secondary node needs to be started when the terminal triggers the state transition process;
b23, a terminal which communicates with the service cell and performs different frequency and/or different technology measurement;
it should be noted that the terminal can perform measurement of the secondary node without affecting the existing state transition process.
Optionally, the configuration information measured by the secondary node in step S11 includes the duration of the secondary node measurement, and after the measurement of the corresponding secondary node is started, a measurement timer T1 is started (the timing duration of the measurement timer is equal to the duration of the secondary node measurement), and after T1 is out of time, the measurement of the corresponding secondary node is stopped.
Optionally, after starting the measurement of the secondary node, the terminal may quickly obtain the measurement result of the secondary node by using one or more of the following manners:
b31, preferentially measuring the auxiliary nodes;
for example, after the terminal starts the measurement of the secondary node, the measurement of the secondary node is preferentially performed, and the measurement of the remaining RRM is performed later, so that the terminal can obtain the measurement result of the secondary node as soon as possible.
Further, whether to prioritize the measurement of the secondary node may be determined based on the priority (i.e., the configuration information of the secondary node measurement in step S11) when the network device configures the measurement; for example, in step S11, if the priority of the measurement configuration of the secondary node is 0, and the priority of the remaining RRM measurements is 2, the terminal preferentially performs the measurement of the secondary node; for example, the measurement configuration of the secondary node includes (measurement object 1, priority 1), (measurement object 2, priority 2), and the priorities of the remaining RRM measurement objects are 2, the terminal preferentially performs the measurement of the measurement object 1 in the secondary node, and then performs the measurement of the measurement object 2 in the secondary node and the measurements of the remaining RRM measurement objects.
B32, suspending other RRM measurements or suspending other RRM measurements except for the primary serving cell;
for example, after the terminal suspends the RRM measurements, the terminal may have more opportunities to perform the measurement of the secondary node, so that the measurement result of the secondary node can be obtained as soon as possible.
B33, using a short measurement period or interval, which may be preconfigured in step S11 or may be a specific value predefined in the protocol. For example, in general, the co-frequency measurement is performed once in 100ms, and at this time, the terminal performs the measurement of the secondary node once every 50ms, so that the measurement result of the secondary node can be obtained as soon as possible.
Step S13, after obtaining the measurement result of the auxiliary node, the terminal reports the measurement result to the network equipment;
and through the report of the measurement result, the auxiliary network side is configured with a proper auxiliary node.
The terminal reports the measurement result of the auxiliary node to the network side, which may be based on one of the following ways:
b41, carrying the measurement result of the auxiliary node in the state transition completion message;
for example, the terminal carries the measurement result of the available secondary node in the RRC setup complete message, the RRC recovery complete message, or the RRC reestablishment complete message.
B42, based on the configuration information in step S11, after the measurement duration time of the auxiliary node is overtime, the terminal reports the measurement result of the auxiliary node;
b43, after obtaining the measurement result of the auxiliary node, the terminal reports the measurement result of the auxiliary node;
for example, once the terminal obtains the measurement result of the available auxiliary node, the terminal triggers the measurement result reporting process of the auxiliary node; or the terminal triggers the measurement result reporting process of the auxiliary node after obtaining the measurement results of all the auxiliary nodes to be measured according to the measurement configuration of the auxiliary node;
b44, the terminal sends the measurement result indication of the available auxiliary node to the network equipment, and then reports the measurement result of the auxiliary node based on the network equipment request;
for example, after obtaining the measurement result of the available auxiliary node, the terminal actively sends the measurement result indication of the available auxiliary node to the network device, the network device judges whether the measurement result of the auxiliary node is needed according to the own requirement, if so, the network device requests the terminal to report the measurement result of the auxiliary node, and the terminal reports the measurement result of the auxiliary node after receiving the request;
b45, the configuration information measured by the auxiliary node carries event configuration information triggering the reporting of the measurement result of the auxiliary node, and the terminal reports the measurement result of the auxiliary node after the predefined event is met;
for example, the configuration information measured by the auxiliary node in step S11 includes "the cell signal quality is greater than a certain threshold", when the terminal measures the auxiliary node, if the signal quality of a certain cell is greater than a certain threshold, the terminal triggers a measurement result reporting process of the auxiliary node; optionally, the terminal may also trigger a measurement result reporting procedure of the secondary node after the signal quality of a certain cell is greater than a certain threshold and lasts for a period of time t (t may be equal to 0, and t may also be preconfigured by the network side or predefined by a protocol).
It should be noted that, alternatively, in step S13, if the terminal does not execute step S13, the terminal may further execute: the terminal can decide which auxiliary node to select for connection according to the measurement result of the auxiliary node.
Note: the measurement of the secondary node includes measurement of the same RAT and different RATs, for example, a cell where the terminal initiates an RRC recovery procedure is an NR cell, and the SN measurement may be an NR measurement, an LTE measurement, or even a WLAN measurement.
In case two, in the process of state transition or after entering a connection state, triggering based on the network side
As shown in fig. 5, the specific implementation process is as follows:
step S21, the terminal obtains the configuration information measured by the auxiliary node;
in the same case, in step S11, the terminal obtains the configuration information measured by the secondary node, and in this case, in step S21, optionally, the configuration information measured by the secondary node may also be directly carried in step S22 described below.
Step S22, the network equipment sends a command for triggering the auxiliary node to measure;
the network device expects to obtain the measurement result of the auxiliary node based on its own algorithm, so as to assist in selecting a suitable auxiliary node for the terminal, and at this time, the network device sends a command for triggering the auxiliary node to perform measurement, where the command may be carried in a state transition process, such as an RRC connection setup message or an RRC connection recovery message, or may be carried in a single RRC message (such as an RRC reconfiguration message) after the terminal enters an RRC connected state. And after receiving the command, the terminal starts the measurement of the auxiliary node.
Optionally, another implementation manner is that the network device directly carries configuration information of the measurement of the auxiliary node in an RRC connection setup message, an RRC connection recovery message, or a single RRC message (for example, an RRC reconfiguration message), and the terminal starts the measurement of the auxiliary node after receiving the configuration information of the measurement of the auxiliary node. The configuration information of the secondary node measurement includes the content in step S11 and/or the configuration information of the secondary node measurement object (i.e., which measurements are measured by the configuration terminal as the secondary node measurement). In this case, step S21 may be omitted.
Step S23, after the terminal receives the trigger message of the network equipment, the measurement of the auxiliary node is started;
step S12 in one specific implementation manner and case is not described herein again.
Step S24, after obtaining the measurement result of the auxiliary node, the terminal can report the measurement result to the network equipment;
and through the report of the measurement result, the auxiliary network side is configured with a proper auxiliary node.
The specific implementation process of reporting is the same as step S13 in case one, and will not be described herein again.
It should be noted that, optionally, the step S24 is that, if the terminal does not execute the step S24, the terminal may further execute: the terminal can decide which auxiliary node to select for connection according to the measurement result of the auxiliary node.
According to the embodiment of the invention, when the terminal triggers the state transition process or receives the indication of starting the auxiliary node measurement sent by the network equipment in the state transition process or after entering the connection state, the measurement of the auxiliary node is started, so that the terminal can be helped to quickly acquire the measurement result of the auxiliary node, and the reliability of network communication is further ensured.
