Description

Method and device for reporting measurement report

Technical Field

The present disclosure relates to the field of communications technologies, and in particular, to a method and an apparatus for reporting a measurement report.

Background

Non-independent (NSA) networking employs a 4G-5G dual connectivity (EN-DC) approach, where a 5G New Radio (NR) control plane is anchored to a 4G long term evolution (long term evolution, LTE), and 5G NR is used to carry traffic for a user plane. The control plane is a channel for signaling needed by sending and scheduling resources, and the user plane is a channel for transmitting user data.

Under NSA networking, the 5G base station is attached to the existing 4G core network, so that the construction of the 5G core network can be omitted, and the 5G deployment process can be accelerated. However, due to the dual connectivity of 4G and 5G, NSA networking is easier to expose the problem of network compatibility than Stand Alone (SA) networking, which results in that LTE cells that may be normally used cannot normally provide services after EN-DC is established.

For example, if the terminal executes a long term evolution voice bearer (voice over long term evolution, VOLTE) service flow and an NR secondary cell group (secondary cell group, SCG) adding flow simultaneously, the VOLTE service flow is affected due to a conflict between some steps in the VOLTE service flow and the NR SCG adding flow, which results in a phenomenon that the terminal drops VOLTE voice.

Disclosure of Invention

Based on the technical scheme, the terminal transmits the INVITE message, which indicates that the terminal is executing the VOLTE service flow. When the terminal executes the VOLTE service flow, the terminal receives measurement configuration information. The terminal pauses sending the measurement report before sending the first indication information. In this way, the network side does not send the SCG configuration information to the terminal because the network side cannot receive the measurement report sent by the terminal, thereby avoiding the terminal from simultaneously executing the adding operation of the NR SCG and the establishing operation of the radio bearer of the voice service. Therefore, the technical scheme of the application can avoid conflict between the adding operation of the NR SCG and the establishing operation of the radio bearer of the voice service, reduce the failure rate of the radio bearer establishment of the voice service, and improve the success rate of the VOLTE service.

1. Dual connection

In the field of wireless communication technology, in order to improve throughput of users, a dual connection (dual connectivity, DC) technology is introduced. The DC may support two or more base stations to simultaneously provide a data transmission service for one terminal. These base stations include a Master Node (MN) and one or more Secondary Nodes (SNs).

The main node is connected with a Core Network (CN) through an S1/NG interface. The main node and the core network at least comprise control plane connection and can also have user plane connection. The S1 interface comprises S1-U/NG-U and S1-C/NG-C. Wherein S1-U/NG-U represents user plane connection and S1-C/NG-C represents control plane connection.

The secondary node may or may not have a user plane connection with the core network. When there is no user plane connection between the secondary node and the core network, data of the terminal may be shunted to the secondary node by the primary node at a packet data convergence protocol (packet data convergence protocol, PDCP) layer. The primary node may also be referred to as a primary base station or primary access network device, and the SN may also be referred to as a secondary base station or secondary access network device.

In the dual connectivity scenario, the primary node manages one primary cell (PCell). The primary cell is a cell deployed at a primary frequency point and accessed in an initial connection establishment process or an RRC connection reestablishment process initiated by the terminal, or a cell indicated as the primary cell in a handover process.

Further, the primary node may manage one or more secondary cells (scells) in addition to the primary cell. The cells under the primary node that serve the terminal, such as the primary cell, the secondary cells under the primary node, may be collectively referred to as a primary cell group (master cell group, MCG).

The secondary node manages one primary and secondary cell (primary secondary cell, PSCell). The primary and secondary cells may be cells that the terminal initiates access in a random access process to the secondary node, or cells on another secondary node that the terminal skips over the random access process to initiate data transmission in a secondary node change process, or cells on a secondary node that initiates access in the random access process when a synchronous reconfiguration process is performed.

Further, the secondary node may manage one or more secondary cells in addition to the primary and secondary cells. The cells on the secondary node that serve the terminal, such as the primary secondary cell, the secondary cell on the secondary node, may be collectively referred to as SCG.

For convenience of description, in the NR protocol, a primary cell and a primary and secondary cell are collectively referred to as a specific cell (SpCell).

In the embodiment of the application, the terminal is a device with a wireless transceiving function. Terminals may be deployed on land, including indoors or outdoors, hand-held or vehicle-mounted; may also be deployed on the surface of water (e.g., a ship, etc.); but may also be deployed in the air (e.g., on aircraft, balloon, satellite, etc.). The terminal may be a User Equipment (UE). The UE includes a handheld device, an in-vehicle device, a wearable device, or a computing device with wireless communication functionality. The UE may be a mobile phone (mobile phone), a tablet computer, or a computer with a wireless transceiver function, for example. The terminal may also be a Virtual Reality (VR) terminal device, an augmented reality (augmented reality, AR) terminal device, a wireless terminal in industrial control, a wireless terminal in unmanned, a wireless terminal in telemedicine, a wireless terminal in smart grid, a wireless terminal in smart city, a wireless terminal in smart home, etc. In this embodiment of the present application, the device for implementing the function of the terminal may be the terminal, or may be a device capable of supporting the terminal to implement the function, for example, a chip system. In the embodiment of the application, the chip system may be formed by a chip, and may also include a chip and other discrete devices.

The primary node and the secondary node may be collectively referred to as a network device. The network devices include, but are not limited to: an Access Point (AP) in a wireless fidelity (wireless fidelity, wiFi) system, such as a home gateway, a router, a server, a switch, a bridge, etc., an evolved Node B (eNB), a radio network controller (radio network controller, RNC), a Node B (Node B, NB), a base station controller (base station controller, BSC), a base transceiver station (base transceiver station, BTS), a home base station (e.g., home evolved Node B, or home Node B, HNB), a baseband unit (BBU), a wireless relay Node, a wireless backhaul Node, a transmission point (transmission and reception point, TRP, transmission point, TP), etc., may also be a 5G, such as a gcb in a new air interface (NR) system, or a transmission point (TRP, TP), an antenna panel of one or a group (including a plurality of antenna panels) of base stations in a 5G system, or may also be a network Node constituting a gcb or transmission point, such as a baseband unit (BBU), a distributed base station unit (rsdu), etc., a base station unit (base station unit, a distributed unit, etc.

In the embodiment of the present application, the network device may employ a Centralized Unit (CU) -DU architecture. That is, the network device may be composed of a CU and at least one DU. In this case, part of the functions of the network device are deployed on the CU, and another part of the functions of the network device are deployed on the DU. CU and DU are functionally sliced according to the protocol stack. As one implementation, a CU is deployed with an RRC layer, a packet data convergence layer protocol (packet data convergence protocol, PDCP) layer, and a service data adaptation protocol (service data adaptation protocol, SDAP) layer in a protocol stack; the DU is deployed with a radio link control (radio link control, RLC) layer, a media intervening control (media access control, MAC) layer, and a physical layer (PHY) in the protocol stack. Thus, the CU has the processing capabilities of RRC, PDCP and SDAP. The DU has the processing power of RLC, MAC and PHY. It is to be understood that the above-described segmentation of functions is only one example and does not constitute a limitation on CUs and DUs. That is, there may be other manners of function segmentation between the CU and the DU, which is not described herein in detail in this embodiment.

Depending on the communication schemes supported by the primary node and the secondary node, the dual connectivity network may be implemented in a variety of ways, as exemplified below.

As shown in fig. 1, a schematic diagram of an LTE-NR dual connectivity (E-UTRA-NR Dual Connectivity, EN-DC) network is shown. The EN-DC network is a dual connection of a 4G radio access network with 5G NR, with LTE base station (LTE eNB) as MN and NR base station (NR gNB) as SN. As shown in fig. 1 (a), there is an S1 interface between the LTE eNB and the evolved packet core (evolved Packet Core, EPC) of the LTE system, and at least a control plane connection, and possibly a user plane connection. As shown in fig. 1 (b), there is an S1-U interface between the NR gNB and EPC, i.e. only a user plane connection.

As shown in fig. 2, a schematic diagram of an NR-LTE dual connectivity (NR-E-UTRA Dual Connectivity, NE-DC) network is shown. The NE-DC network is a dual connection of a 4G radio access network under a 5G core network with a 5G NR, an NR base station (gNB) as MN, an LTE base station (ng-eNB) as SN, and both MN and SN are connected to the 5G core network (5th Generation Core Network,5GC). As shown in fig. 2 (a), an NG interface exists between the gNB and the 5GC, and a control plane connection and a user plane connection can be established for the terminal, and the NG-eNB sends user plane data to the 5GC through the gNB. As shown in (b) of fig. 2, there is an NG-U interface between the NG-eNB and the 5GC, and only the user plane connection is established for the terminal, the NG-eNB directly transmits the user plane data to the 5 GC.

As shown in fig. 3, a schematic diagram of a 5G core network LTE-NR dual connectivity (Next Generation E-UTRA-NR Dual Connectivity, NGEN-DC) network is shown. The NGEN-DC network is a dual connection of a 4G radio access network under a 5G core network with 5G NR, an LTE base station (ng-eNB) is used as MN, an NR base station (gNB) is used as SN, and both MN and SN are connected with 5GC. As shown in fig. 3 (a), an NG interface exists between the NG-eNB and the 5GC, a control plane connection and a user plane connection may be established for the terminal, and the gNB sends user plane data to the 5GC through the NG-eNB. As shown in (b) of fig. 3, there is an NG-U interface between the gNB and the 5GC, and only the user plane connection is established for the terminal, and the gNB directly transmits the user plane data to the 5GC.

In the dual connectivity network of fig. 1-3, the user plane connection may not be established between the SN and the core network, but data may be transferred via the MN, e.g. in the downlink direction, the data of the terminal arrives first at the MN, the MN shunts the data of the terminal to the SN in the PDCP layer, wherein the shunted data is in the form of PDCP protocol data units (Protocol Data Unit, PDU), for example.

2. EPS bearer

After the UE attaches to the LTE network, a corresponding EPS bearer (bearer) needs to be established on the LTE network side before the UE initiates an IMS registration procedure and a subsequent IMS session procedure. The EPS bearer is used to transport IMS SIP signaling messages and user voice data packets.

One EPS bearer consists of an evolved radio access bearer (evolved radio access bearer, E-RAB) and an S5 interface bearer (S5 bearer). Wherein the E-RAB is composed of Radio Bearers (RBs) of an air interface (Uu) and S1 interface bearers (S1 beaerers).

The RB of the Uu interface can be further divided into a signaling radio bearer (signaling radio bearer, SRB) and a data radio bearer (data radio bearer, DRB).

SRBs can be classified into the following 3 categories:

(1) SRB0: is established on a common control channel (common control channel, CCCH) for transmitting RRC layer signaling messages.

(2) SRB1: is established on a dedicated control channel (dedicated control channel, DCCH) and is mainly used for transmitting RRC layer signaling messages, and NAS layer messages can be transmitted together with RRC layer signaling messages in an embedded manner.

(3) SRB2: after the security mode is completed, the NAS message is exclusively transmitted in a reliable and secure manner, established on the DCCH.

The DRB is used to carry user plane data. Depending on the QoS, a maximum of 8 DRBs may be established between the UE and the base station.

3、QCI

QCI is a parameter used by the system to identify the transmission characteristics of the traffic data packets.

For example, as shown in table 1, the QCI has meanings corresponding to different values. One QCI contains mainly the following information: resource type (resource type), priority (priority), data latency (packet delay budget), and data packet loss rate (packet error loss rate).

As shown in table 1, EPS bearers can be divided into guaranteed bit rate (guaranteed bit rate, GBR) class bearers and Non-GBR class bearers according to the difference in QCI.

GBR refers to the bit rate that the bearer requires to be maintained even in case of network resource shortage. Therefore, GBR class bearers are used for traffic with high real-time requirements.

Non-GBR refers to the requirement that the bearer be subject to reduced bit rate in case of network congestion. The Non-GBR class bearer is used for the service with low real-time requirement.

The IMS comprises a plurality of network elements, e.g. call session control functions (call session control function, CSCF) network elements, home subscriber servers (home subscriber server, HSS), etc.

The VOLTE service flow between the calling terminal and the called terminal is described below in connection with the communication system shown in fig. 4.

The INVITE message is used to indicate that the calling terminal initiates a voice session to the called terminal. The INVITE message includes the number of the calling terminal, the media type and code supported by the calling terminal, and the like.

If the calling terminal is in idle state, the calling terminal performs the following steps S102-S105 in order to transmit the INVITE message and the subsequent message of the VOLTE service flow.

If the originating terminal is in a connected state, i.e. the originating terminal has established an RRC connection with the access network device #1, the originating terminal may not need to perform an RRC procedure.

Illustratively, the originating terminal receives an RRC connection reconfiguration (RRC connection reconfiguration) message sent by access network device # 1. Thereafter, the originating terminal transmits an RRC connection reconfiguration complete (RRC connection reconfiguration complete) message to the access network device # 1.

Wherein, the INVITE100 (INVITE) message is a temporary response to the INVITE message transmitted by the calling terminal. An INVITE100 (transmission) message is used to indicate that an INVITE message sent by a calling terminal is being processed.

It will be appreciated that the communication system needs to perform the following steps S107-S111 when the called terminal is in an idle state.

Wherein, the INVITE 100 message is used to indicate that the called terminal receives the INVITE message sent by epc#2.

S114, the called terminal sends an INVITE 183 message to the IMS.

Wherein the INVITE 183 message indicates that a current session (dialog) is being processed, the INVITE 183 message includes media types and encodings supported by the called terminal.

It should be understood that the called terminal initiates a resource reservation (Precondition) procedure of the called terminal by transmitting an INVITE 183 message.

And S115, an EPS bearing establishment (EPS bearing setup) flow is executed between the called terminal and the EPC#2.

The EPS bearer setup procedure is used to establish a dedicated EPS bearer with qci=1.

The PRACK message is used to indicate that the calling terminal acknowledges receiving the INVITE 183 message.

And S119, the IMS sends a PRACK message to the called terminal.

S120, the called terminal sends PRACK 200 message to IMS.

The PRACK 200 message is used to indicate that the called terminal acknowledges that the PRACK message is received.

Wherein the UPDATE message is used to indicate that the resource reservation process of the calling terminal is completed.

S123, the IMS sends an UPDATE message to the called terminal.

S124, the called terminal sends an UPDATE 200 message to the IMS.

Wherein the UPDATE 200 message is used to indicate that the resource reservation procedure of the called terminal has been completed.

And S136, executing a procedure of deactivating EPS bearing context (deactivate EPS bearer context) between the calling terminal and the IMS.

Wherein deactivate EPS bearer context procedure is used to deactivate dedicated EPS bearers with qci=1.

In the deactivate EPS bearer context flow, the calling terminal releases the DRB corresponding to the dedicated EPS bearer with qci=1.

It should be appreciated that the default EPS bearer with qci=5 always exists on the core network side (i.e. epc#1). When the originating terminal enters a connected state, the epc#1 notifies the access network device#1 to configure SRBs and DRBs corresponding to default EPS bearers with qci=5 for the originating terminal. When the originating terminal enters an idle state, the epc#1 instructs the originating terminal to release SRBs and DRBs corresponding to default EPS bearers with qci=5 through the access network device#1.

And S137, executing deactivate EPS bearer context flow between the called terminal and the IMS.

The foregoing is a brief description of the VOLTE service flow, and specific details thereof may refer to the prior art and are not described herein.

Currently, in the early stages of 5G deployment, in order to save costs and develop services quickly, a part of operators select a non-independent Networking (NSA) mode. NSA employs EN-DC architecture.

In the case of EN-DC architecture, as shown in fig. 6, the NR SCG addition flow includes the following steps:

s201, the access network equipment sends measurement configuration information to the terminal.

Wherein, the measurement configuration information is carried in an RRC connection reconfiguration message. The measurement configuration information may be exemplified as an NR measurement cell in RRC connection reconfiguration information.

The measurement configuration information is used for indicating NR frequency point information which needs to be measured by the terminal. Optionally, the measurement configuration information may also include a NR cell list.

The measurement configuration information is also used for indicating the duration of a configuration time (time to trigger) and the reporting requirement of a measurement report.

It should be understood that after step S201, the terminal performs measurement on the NR cell according to the measurement configuration information. If the measurement result of the NR cell meets the measurement report reporting requirement within the configuration time, the terminal may execute step S202 described below.

S202, the terminal sends a measurement report to the access network equipment (measurement report).

S203, the access network equipment sends RRC connection reconfiguration information carrying SCG configuration information to the terminal.

After the terminal receives the SCG configuration information, the terminal establishes at least two DRB bearers. For convenience of description, one of the two DRB bearers is simply referred to as a first DRB bearer and the other DRB bearer is simply referred to as a second DRB bearer.

Wherein the first DRB bearer belongs to a part of EPS bearer with qci=5, and is used for carrying IMS-specific signaling. The first DRB is independent of whether a voice call is initiated or not, and only whether RRC enters a connected state or not.

The second DRB is used to carry data traffic.

S204, the terminal sends an RRC connection reconfiguration complete (RRC connection reconfiguration complete) message to the access network device.

Currently, the VoLTE service flow shown in fig. 5 and the NR SCG addition flow shown in fig. 6 are independent from each other, and there is a possibility that both flows are performed simultaneously. In the outfield test, when the VoLTE service flow and the NR SCG addition establishment flow are performed simultaneously, before the dedicated EPS bearer of qci=1 is not established, adding SCG easily causes the context of the dedicated EPS bearer of qci=1 to be lost, thereby causing the dedicated EPS bearer of qci=1 to be failed to be established, and finally causing the phenomenon of VoLTE voice call drop to occur.

Wherein adding SCG easily results in a context loss of dedicated EPS bearers of qci=1, in particular because: the terminal establishes a DRB corresponding to the dedicated EPS bearer with qci=1, which may collide with a DRB established by the terminal when the SCG is added and used for carrying data services, so that the terminal does not correctly establish a DRB corresponding to the dedicated EPS bearer with qci=1.

In order to solve the above technical problems, an embodiment of the present application provides a measurement report reporting method. As shown in fig. 7, the method includes the steps of:

s301, the terminal transmits an INVITE message.

The terminal may be a calling terminal or a called terminal in the VOLTE service flow.

Alternatively, the INVITE message may contain the session type and at least one parameter for the call. The session types may include: voice sessions, multimedia video sessions, etc. Illustratively, the parameters for the call may be: number of calling terminal, media type and code supported by calling terminal, etc.

Alternatively, when the terminal is a calling terminal, step S301 may be specifically implemented as: the terminal transmits an INVITE message.

Alternatively, when the terminal is a called terminal, step S301 may be specifically implemented as: the terminal receives the INVITE message.

S302, the terminal receives measurement configuration information sent by the first access network equipment.

The first access network equipment supports a 4G communication system. The first access network device is the access network device accessed by the terminal.

In the embodiment of the application, the measurement configuration information is used for configuring the terminal to measure the NR cell.

By way of example, the measurement configuration information may include one or more of the following parameters: measurement objects, cell lists, reporting modes, measurement identities, event parameters, etc. The measurement object is used to indicate the radio access type (radio access type, RAT) that needs to be measured, such as NR, EUTRA, etc. The cell list includes one or more cell identities. The reporting mode can be periodical reporting or event-triggered reporting. The event parameters may include the number of events, threshold values, configuration time, etc.

Alternatively, after the terminal receives the measurement configuration information, the terminal may take one of the following operations:

operation 1, the terminal pauses the measurement of the cell until the terminal establishes the radio bearer of the voice service.

In LTE, the radio bearer of the voice service refers to a DRB corresponding to a dedicated EPS bearer with qci=1.

It should be understood that based on operation 1, the terminal may not perform a measurement operation, thereby reducing power consumption of the terminal.

And 2, the terminal measures the cell according to the measurement configuration information and stores measurement data.

It should be understood that, based on operation 1, in the case where the terminal is allowed to transmit the measurement report, the terminal may feed back the measurement report to the first access network device according to the previously stored measurement data, reducing the delay of feeding back the measurement report.

In the embodiment of the application, in order to avoid that the NR SCG adds the context of the radio bearer which causes the loss of the voice service, when the terminal does not establish the radio bearer of the voice service, the terminal pauses sending the measurement report; the terminal is allowed to transmit the measurement report after the terminal establishes a radio bearer for the voice service.

The terminal establishes a radio bearer of the voice service, and the method comprises the following steps: the terminal receives first request information from the first EPC, the first request information being for requesting establishment of a radio bearer for voice services. And the terminal establishes the context of the radio bearer of the voice service according to the first request information. Then, the terminal sends first indication information to the first EPC, where the first indication information is used to indicate a radio bearer for the established voice service. Wherein the first EPC is the EPC that serves the terminal.

The transmission process of the first request information is as follows: the first EPC sends an E-RAB establishment request (E-RAB SETUP REQUEST) to the first access network device, with E-RAB SETUP REQUEST carrying the first request information. Thereafter, the first access network device sends an RRC connection reconfiguration (RRC connection reconfiguration) message to the first terminal according to the E-RAB establishment request, the RRC connection reconfiguration message carrying the first request information.

Exemplary, the transmission process of the first indication information is: the first terminal sends an uplink information transfer (UL information transfer) message to the first access network device, the uplink information transfer message carrying the first indication information. And then, the first access network equipment sends an uplink non-access transmission (UL NAS transport) message carrying first indication information to the first EPC according to the uplink information transfer message.

Alternatively, the first request information may have other names, such as an activate dedicated EPS bearer context request message (activate dedicated EPS bearer context request). The first indication information may have other names, such as an activate dedicated EPS bearer context accept message (activate dedicated EPS bearer context accept).

It should be understood that the terminal does not transmit the first indication information, which indicates that the terminal has not completed the establishment of the radio bearer for the voice service, and thus the terminal performs step S303 described below. The terminal transmits first indication information indicating that the terminal completes the establishment of the radio bearer of the voice service, so the terminal performs step S304 described below.

S303, before the terminal sends the first indication information, the terminal pauses sending the measurement report.

In a possible implementation manner, the suspension of sending the measurement report by the terminal may be specifically implemented as follows: the terminal does not perform cell measurement and thus does not generate a corresponding measurement report, so the terminal does not need to send the measurement report.

In another possible implementation manner, the suspension of sending the measurement report by the terminal may be specifically implemented as follows: the terminal performs cell measurement, but no matter whether the measurement result of the NR cell meets the measurement report reporting requirement or not, the terminal defaults that the measurement result of the NR cell does not meet the measurement report reporting requirement, so the terminal does not generate a corresponding measurement report and does not need to send the measurement report.

S304, the terminal sends a measurement report after sending the first indication information.

Wherein the measurement report includes: measurement results of one or more NR cells. The measurement result of the NR cell may be, for example, the reference signal received power (reference signal receiving power, RSRP) and/or the reference signal received quality (reference signal receiving quality, RSRQ) of the NR cell.

Optionally, the terminal performs cell measurement after sending the first indication information. Therefore, when the measurement result of the NR cell meets the measurement report reporting requirement, the terminal generates a corresponding measurement report and sends the measurement report to the first access network equipment.

Based on the embodiment shown in fig. 7, after the terminal receives or sends the INVITE message, before the terminal establishes the radio bearer of the voice service, the terminal pauses sending the measurement report, so that the network side will not trigger the terminal to perform the addition operation of the NR SCG, thereby avoiding the conflict between the addition operation of the NR SCG and the establishment operation of the radio bearer of the voice service. Therefore, the embodiment of the application is used for reducing the failure rate of the radio bearer establishment of the voice service and improving the success rate of the VOLTE service.

Optionally, on the basis of the embodiment shown in fig. 7, as shown in fig. 8, the method may further include, after step S304, the following steps:

s305, the terminal receives an RRC connection reconfiguration message carrying SCG configuration information, which is sent by the first access network equipment.

It should be understood that after the first access network device receives the measurement report sent by the terminal, the first access network device may determine, according to the measurement report, whether to add a second access network device as an auxiliary node of the terminal, where the second access network device supports the 5G format. In case the first access network device determines to add the second access network device as a secondary node of the terminal, the first access network device may send a secondary node addition request (SgNB addition request) to the second access network device, the secondary node addition request comprising RRC configuration information, radio bearer configuration information, etc. The second access network device sends a secondary node addition request acknowledgement (SgNB addition request acknowledge) message to the first access network device. And the first access network equipment sends an RRC connection reconfiguration message carrying SCG configuration information to the terminal according to the auxiliary node addition request confirmation message.

The SCG configuration information comprises SCG information to be added and NR DRB resource configuration information.

After the terminal receives the RRC connection reconfiguration message, the terminal analyzes the RRC connection reconfiguration message and acquires the SCG configuration information. And then, the terminal determines the 5G wireless resource according to the SCG configuration information. Thus, in a subsequent step, the terminal may communicate with the second access network device over the 5G radio resource.

S306, the terminal sends RRC connection reconfiguration complete information to the first access network equipment.

In this way, the first access network device can learn that the terminal has completed RRC connection reconfiguration according to the RRC connection reconfiguration complete message sent previously. Thus, the first access network device may send a secondary node reconfiguration complete (SgNB Reconfiguration complete) message to the second access network device.

And then, the terminal can execute a random access procedure with the second access network equipment so as to realize the synchronization between the terminal and the second access network equipment.

Based on the embodiment shown in fig. 7, the network side may add SCG to the terminal, so that the terminal may use a dual-connection mode to perform communication, thereby improving the data transmission speed of the terminal.

The embodiment shown in fig. 7 is described below in connection with a specific application scenario.
