Fig. 4 is referred to, Fig. 4 is a kind of flow diagram of communication means provided in an embodiment of the present invention, and this method includes but is not limited to following steps.

Step S401: the terminal obtains the first signal quality and the first bandwidth.

Specifically, which characterizes received signal quality of the terminal currently in the cell of the first base station, which characterizes the current bandwidth of the first radio resource link.The received signal quality for the cell that UE meeting real-time detection itself is resident, therefore the available received signal quality to certainly in SCG of the UE, since the SCG is provided by first base station, therefore it also can be described as obtaining signal quality of the UE in first base station, the signal quality currently obtained is properly termed as the first signal quality.The signal strength that UE measures the cell itself being resident is prior art, and details are not described herein again；It is understood that the parameter of the height of signal quality can by reference to signal reception power (English: Reference Signal Receiving Power, referred to as: RSRP), Reference Signal Received Quality (English: ReferenceSignalReceivingQuality, referred to as: RSRQ), the parameters such as received signal strength indicator (English: Received Signal Strength Indication, referred to as: RSSI) are measured.

In addition, radio resource link between UE and first base station is properly termed as the first radio resource link, first radio resource link can refer to the ascending wireless resource link between the UE and the first base station from the perspective of uplink and downlink, it can also refer to the downlink radio resource link between the UE and the first base station, can also refer to downlink radio resource link and ascending wireless resource link between the UE and the first base station；The first radio resource link can refer to the radio resource control link between the UE and the first base station from the perspective of upper carrying data type, it can also refer to the radio resource data link between the UE and the first base station, can also refer to radio resource control link and radio resource data link between the UE and the first base station.Radio resource link between UE and the second base station is properly termed as the second radio resource link, second radio resource link can refer to the ascending wireless resource link between the UE and second base station from the perspective of uplink and downlink, it can also refer to the downlink radio resource link between the UE and second base station, can also refer to downlink radio resource link and ascending wireless resource link between the UE and second base station；The second radio resource link can refer to the radio resource control link between the UE and second base station from the perspective of upper carrying data type, it can also refer to the radio resource data link between the UE and second base station, can also refer to radio resource control link and radio resource data link between the UE and second base station.

When UE is connected to some cell, the bandwidth of the link of the UE in the cell is a determining value, the UE can directly acquire the value, such as, the bandwidth notified to know the link that can be sent by the cell, the bandwidth of the link can also be detected with itself, the bandwidth of the link currently obtained can be described as the first bandwidth.

When first signal quality is higher than preset second signal quality, and first bandwidth meet carry the terminal business demand when, otherwise it is constant to retain the current state (i.e. business state) of radio resource link between the terminal and the second base station by i.e. executable step S402.Optionally, second signal quality herein can be the terminal currently received signal quality in second base station (also can be described as the terminal real-time received signal quality in the SCG), an or fixed value for being used to make reference to be gone out according to the value analysis and summary for characterizing signal quality in historical record.

Business demand herein may include several biography demands, as soon as UE needed to receive more data within the unit time just and can guarantee and downloaded the HD video as early as possible this when for example, UE needs to download the very big HD video of a data volume；Be conducive to the UE if the bandwidth that the UE receives data is bigger and received the HD video within the shorter time, which can determine required bandwidth according to the size for the data that itself currently to be transmitted.If first band, which is wider than, transmits bandwidth required for data equal to the UE, show that the first bandwidth meets the demand for carrying the business of the terminal.Such as, if the SCG can be that the bandwidth that the UE is provided is 10,000,000 (M), and UE bandwidth actually required is 15,000,000 (M), so SCG is not able to satisfy the demand for carrying the business of the UE, if the SCG can be that the bandwidth that the UE is provided is 10,000,000 (M), and UE bandwidth actually required is 5,000,000 (M), then the SCG is able to satisfy the demand for carrying the business of the UE.

It should be noted that the sequencing of operation with the operation for obtaining the first bandwidth of the first signal quality is obtained herein without limitation, in addition, the handling capacity of SCG locating for the UE is higher than the handling capacity of MCG locating for the UE.For example, the SCG is using 5G technology, the MCG is using LTE technology, and in this case the handling capacity of the SCG is higher than the handling capacity of the MCG.

Step S402: the UE transmission link maintains instruction.

Specifically, which maintains instruction for trigger the second base station (can also abbreviation " base station " to distinguish with " first base station ") for link configuration of the UE in the MCG as dormant state or light connected state.In embodiments of the present invention, Link configuration of the UE in the MCG can be different states according to the demand of UE by two base stations, the state of the link can be dormant state (English: dormant state), light connected state Light RRC connection, activated state (English: active state), etc., wherein, activated state refers to link just in the state of transmission services；Under the dormant state, air traffic channels are not present between the terminal and second base station, and there is no the contextual informations for accessing second base station；Air traffic channels are not present between the terminal and second base station, but the terminal and second base station are stored with the contextual information for accessing second base station respectively.

It should be noted that will appear the connection Connected state of UE in some cases, Connected state is divided into 2 sub-states again, one is Scheduled state, some is also activated state or synchronous state, another kind is Non-Scheduled state, and some is also called activated state or step-out state；In other words, there is also other calls for activated state described in the embodiment of the present invention, but the essence embodied is really identical.Contextual information is introduced below, when UE is in attachment state (non-idle state), its context may include such as cell phone network ability, tracking area identification (Tracking Area Identity, TAI), S1APID, base station number (eNodeBID), authentication information, the security algorithm of negotiation, the key of generation, link information (such as access point name (the Access Point Name of creation, APN), public data network (Public Data Network, PDN) gateway (PDN GateWay, PGW), qos parameter (QoS Class Identifier, QCI)), carrying information, (core is net loaded Identify (Evolved Packet System Bearer Identifier, EBI), QCI, uplink and downlink Aggregate Maximum Bit Rate (Aggregated Maximum Bit Rate, AMBR), magnitude of traffic flow template (Traffic Flow Template, TFT), control plane and user face address etc.) etc..Before the UE is not separated, these information are all to preserve, otherwise UE carries out tracing section updating (Tracking Area Update, TAU), when the behaviors such as service request ServiceRequest, attachment removal Detach, it can not just carry out handling, because second base station can not find the context of the UE, agreement (the IPInternet Protocol interconnected between its network is not just known, IP), it is connected PGW, it create those carryings, the message of its possible transmission can not all decrypt.In a communications system, occurs " context foundation " this saying often, what is referred in fact is exactly the foundation of context session, is primarily referred to as establishing connection between functional entity, is transmitted for information.For example RRC is established between UE and the functional entity of the second base station two, its communication link is exactly context.In second generation wireless communication technique (The 2nd Generation, 2G), 3rd generation mobile communication technology (3rd-Generation, context is primarily referred to as packet data protocol (Packet Data Protocol in 3G), PDP) context, refer to PDP activation gateway general packet radio service (General Packet Radio Service, GPRS the process of link) is established between supporting node (Gateway GPRS Support Node, GGSN).Context in LTE is primarily referred to as EPS bearer context, is the process for the connecting link established between UE and PGW.The foundation of context session includes four parts: encryption (for example, between UE and eNodeB) of eating dishes without rice or wine, terminal capability inquiry, signaling bear (SRB2) and Deta bearer (DRB).When terminal and mobile management unit (Mobility Management Entity, when being communicated between MME), need first to establish context session request, this is initiated by MME, conversation procedure is exactly the process for establishing carrying, including signaling bear (SRB2), Deta bearer (DRB)；Signaling bear, which has been built, can be carried out Signalling exchange, and Deta bearer has been built, so that it may send/received data packet.

It should be noted that, the embodiment of the present invention description dbjective state (such as, dormant state, light connected state etc.) it is a kind of state between IDLE state (also referred to as " Idle state ") and CONNECTED state (also referred to as " connected state "), simple introduce to facilitate and understand is carried out to IDLE state and CONNECTED state below:

IDLE state: if without Non-Access Stratum (Non-Access Stratum, NAS) signaling connection between UE and network, UE is at IDLE state.In IDLE state, UE can execute cell selection/reselection, or carry out PLMN selection. The UE of IDLE state is in access net (RadioAccess Network, it RAN is no UE context in), plane interface S1_MME connection both is controlled without S1 at this time, also without the S1_U connection of S1 interface in the user plane, wherein, S1_MME connection refers to evolved base station (evolved NodeB, eNB) (can refer to the second base station in embodiments of the present invention) to connect with the interface between MME, S1_U connection refers to that the interface between eNB and gateway (Serving GateWay, S-GW) connects.

CONNECTED state: the UE location information in CONNECTED state, MME can be accurate to the degree of the eNB mark of service.In this case, UE can execute changeover program.If TAI in EMM system not Timing Advance (the Timing Advance when UE is registered, TA) in list, UE will execute TAU program, or if the TIN of UE indicates that (TIN is the parameter that UE is saved, it identifies oneself temporary identifier (temporary ID) for using when sending Attach Request/RAU/TAU Request next time) be " P-TMSI ", when being then switched to RAN cell, TAU program is also executed.UE has signaling connection in CONNECTED state between UE and MME.Signaling connection includes two parts: RRC connection is connected with S1_MME.If the signaling connection between UE to MME is released or interrupted, UE will enter IDLE state.

The UE (being also possible to base station) can be configured so that link switching of the UE in the MCG is to activated state, when link of the UE in the MCG is in activated state, which can normally transmit various control face datas and user face data.

It can be understood that, it is dormant state or light connected state that the UE sends a kind of instruction to trigger second base station for link configuration of the UE in the MCG to the second base station, it is activated state that the UE sends another instruction to trigger the base station for link configuration of the UE in the MCG to the second base station, and the instruction that link configuration of the UE in MCG is referred to as dormant state or light connected state is that link maintains to instruct by instruction in the embodiment of the present invention；The instruction that link configuration of the UE in MCG is referred to as activated state is initiation of services instruction by instruction.Under normal conditions, the UE transmission link maintain when instruction link of the UE in MCG to be not at dormant state perhaps light connected state waits base stations to maintain instruction to carry out that dormant state or light connected state can be entered with postponing the link just according to the link；Link of the UE in MCG is not at activated state when the UE sends initiation of services instruction, and base stations is waited to be carried out just entering activated state with postponing the link according to initiation of services instruction.

Step S403: base station receives the link and maintains instruction.

Specifically, the base station is to provide the base station of the MCG, that is the second base station, the base station receive the link maintain instruction include at least two kinds of possibilities, possibility first is that, UE transmission link maintain instruction after, first base station receives the link and maintains instruction, then the link is maintained instruction to be transmitted to the base station by first base station, and correspondingly, the link which receives first base station transmission maintains instruction；Possibility second is that, the base station receive the UE transmission link maintain instruction.

Step S404: it is dbjective state that base station, which maintains to instruct the link configuration by the UE in the MCG according to the link,.

Specifically, link link data transmitted in unit time after being configured as dbjective state can tail off, the dbjective state can be the states such as dormant state, light connected state, link configuration of the UE in MCG is that dbjective state can unilaterally be arranged some parameters by the base station and realize by the base station, or holds consultation to realize with the UE in the base station；After the base station confirms that successfully the link configuration by the UE in MCG is dbjective state, a response response can be sent to the UE to inform that the link configuration by the UE in MCG is for dbjective state, it is of course also possible to not send response response to the UE.By the link configuration be dbjective state after, can save the transmission power of the UE on the link and receive power.

In a kind of optional scheme, step S405~S408, step can also be performed after step S401~S404 S405~S408's is described as follows.

Step S405: the terminal obtains third signal quality and the second bandwidth.

Specifically, the third signal quality characterizes received signal quality of the terminal currently in the cell of the first base station, second bandwidth characterizes the current bandwidth of the first radio resource link, the mode that the terminal obtains third signal quality is identical as the mode of the first signal quality is obtained, only the acquisition opportunity of two kinds of signal qualities is different, and third signal quality is that the link between the UE and the second base station is in the signal quality obtained when dbjective state.The mode that terminal obtains the second bandwidth is identical as the mode of the first bandwidth is obtained, and only the acquisition opportunity of two kinds of bandwidth is different, which is that the link between the UE and the second base station is in the bandwidth obtained when dbjective state.Further, the embodiment of the present invention will also judge whether the third signal quality is less than fourth signal quality, and judge whether second bandwidth meets the demand of the business of carrying terminal.Optionally, fourth signal quality herein can be the terminal real-time signal quality (also can be described as the terminal real-time signal quality in the SCG) in second base station, it or is preset signal quality threshold, when the second signal quality of fourth signal quality and front herein is preset signal quality threshold, the second signal quality and fourth signal quality may it is equal may also be unequal.

In the event of any one situation in following situation, step S406 then can be performed, situation one: the UE determines that third signal quality of the UE in secondary cell group SCG is less than fourth signal quality, situation two: the UE determines that the SCG is unsatisfactory for carrying the demand of the current business of the UE, situation three, situation one and situation two are set up.

Step S406: the UE sends initiation of services instruction, and initiation of services instruction is activated state active state for triggering the second base station for link configuration of the UE in the MCG.

Step S407: the base station receives initiation of services instruction.

Specifically, since the UE is in dual link DC scene, therefore the base station receives initiation of services instruction and includes at least two kinds of possibilities, possibility first is that, after UE sends initiation of services instruction, first base station receives initiation of services instruction, and initiation of services instruction is transmitted to the base station (i.e. the second base station) by first base station, correspondingly, which receives the initiation of services instruction of first base station transmission；Possibility second is that, the base station receive the UE transmission initiation of services instruction.

Step S408: it is activated state active state that the base station, which instructs the link configuration by the UE in the MCG according to the initiation of services,.

Specifically, it can be that the base station is unilaterally arranged some parameters and realizes which, which is activated state by link configuration of the UE in MCG, or hold consultation to realize with the UE in the base station；After the base station confirms that successfully the link configuration by the UE in MCG is activated state, a response response can be sent to inform that the link configuration by the UE in MCG is for activated state to the UE, it is of course also possible to not send response response to the UE.Fig. 5 A is the interaction schematic diagram of above-mentioned possibility one, and Fig. 5 B is the interaction schematic diagram of above-mentioned possibility two.

In method shown in Fig. 4, if first signal quality of the terminal under dual link DC scene in the cell of first base station is good enough, and the first bandwidth of the first radio resource link meets the demand for carrying the business of the terminal, so second base station of terminal request (can also referred to as " base station " to distinguish with " first base station ") be by the second radio resource link configuration as dormant state or light connected state, so, the terminal can control face data and user face data by the first radio resource link transmission, without controlling face data and user face data by the second radio resource link transmission；Since the second radio resource link configuration is not nullified the second radio resource link for dormant state or light connected state by the base station, therefore there is no causing second base station to interact signaling with core net because nullifying the second radio resource link, the expense of the second base station and core net is greatly saved.Optionally, if terminal under subsequent dual link DC scene this first Third signal quality in the cell of base station is not good enough, or the first radio resource link is unsatisfactory for carrying the demand of the business of the terminal, so second base station of terminal request (can also referred to as " base station " to distinguish with " first base station ") be by the second radio resource link configuration as activated state, this process is without re-establishing new radio resource link, therefore the expense of the second base station and core net is further also saved there is no causing the second base station to interact signaling with core net because of newly-built radio resource link.

Fig. 6 A is referred to, Fig. 6 A is a kind of flow diagram of communication means provided in an embodiment of the present invention, and this method includes but is not limited to following steps.

Step S601: the base station obtains the first signal quality and the first bandwidth.

Specifically, first signal quality characterizes received signal quality of the terminal currently in the cell of the first base station, and first bandwidth characterizes the current bandwidth of the first radio resource link.(" base station " of subsequent descriptions is " the second base station " abbreviation for the base station, for being distinguished with first base station) it can the received signal quality of cell be resident in the terminal UE of real-time detection terminal, therefore the available received signal quality to the UE in SCG in the base station, since the SCG is provided by first base station, therefore it also can be described as obtaining signal quality of the UE in first base station, the received signal quality currently obtained is properly termed as the first signal quality.Currently, it is prior art that base station side, which detects UE in the signal strength of be resident cell, details are not described herein again；It can be understood that, the parameter of the height of signal quality can be by reference to signal reception power (English: Reference Signal Receiving Power, referred to as: RSRP), Reference Signal Received Quality (English: ReferenceSignalReceivingQuality, referred to as: RSRQ), the parameters such as received signal strength indicator (English: Received Signal Strength Indication, referred to as: RSSI) are measured.

When UE is connected to some cell, the bandwidth of the link of the UE in the cell is a determining value, the bandwidth is assured that when establishing the link, the other equipment of the base station or network side might have stored the information of the bandwidth, when the bandwidth information of the not stored link in the base station, the bandwidth information of the link can be obtained by carrying out data interaction with the other equipment.The bandwidth of link (i.e. the first radio resource link) between the UE that the base station obtains and first base station is properly termed as the first bandwidth.

When first signal quality is higher than preset second signal quality, and first bandwidth meets the demand for carrying the business of the terminal, i.e., otherwise executable step S602 retains radio resource link (i.e. the second nothing between the terminal and the second base station Line link resource) current state (i.e. business state) is constant.Optionally, second signal quality herein can be the terminal real-time signal quality (also can be described as the terminal real-time signal quality in the SCG) in the base station, or a fixed value for being used to make reference to be gone out according to the value analysis and summary for characterizing signal quality in historical record.

Business demand herein may include several biography demands, as soon as UE needed to receive more data within the unit time just and can guarantee and downloaded the HD video as early as possible this when for example, UE needs to download the very big HD video of a data volume；Be conducive to the UE if the bandwidth that the UE receives data is bigger and receive the HD video within the shorter time, the UE can determine required bandwidth according to the size for the data that itself currently to be transmitted, then itself current desired bandwidth information wanted is sent to base station by the terminal, and base station can determine bandwidth required for the UE current transmission data based on the bandwidth information.If first band, which is wider than, transmits bandwidth required for data equal to the UE, show that the first bandwidth meets the demand for carrying the business of the terminal.Such as, if the SCG can be that the bandwidth that the UE is provided is 10,000,000 (M), and UE bandwidth actually required is 15,000,000 (M), so SCG is not able to satisfy the demand for carrying the business of the UE, if the SCG can be that the bandwidth that the UE is provided is 10,000,000 (M), and UE bandwidth actually required is 5,000,000 (M), then the SCG is able to satisfy the demand for carrying the business of the UE.

Step S602: the second radio resource link configuration is dbjective state by the base station.

Specifically, link link data transmitted in unit time after being configured as dbjective state can tail off, the dbjective state can be configured as data transmitted in unit time after the dbjective state for the states such as dormant state, light connected state, the radio resource link and tail off.In embodiments of the present invention, link configuration of the UE in the MCG can be different states according to the demand of UE by the second base station, the state of the link can be dormant state (English: dormant state), light connected state Light RRC connection, activated state (English: active state), etc.；Air traffic channels are not present between the terminal and second base station, and there is no the contextual informations for accessing second base station；Air traffic channels are not present between the terminal and second base station, but the terminal and second base station are stored with the contextual information for accessing second base station respectively.

It should be noted that will appear the connection Connected state of UE in some cases, Connected state is divided into 2 sub-states again, one is Scheduled state, some is also activated state or synchronous state, another kind is Non-Scheduled state, and some is also called activated state or step-out state；In other words, there is also other calls for activated state described in the embodiment of the present invention, but the essence embodied is really identical.Contextual information is introduced below, when UE is in attachment state (non-idle state), its context may include such as cell phone network ability, tracking area identification (Tracking Area Identity, TAI), S1APID, base station number (eNodeBID), authentication information, the security algorithm of negotiation, the key of generation, link information (such as access point name (the Access Point Name of creation, APN), public data network (Public Data Network, PDN) gateway (PDN GateWay, PGW), qos parameter (QoS Class Identifier, QCI)), carrying information, (core is net loaded Identify (Evolved Packet System Bearer Identifier, EBI), QCI, uplink and downlink Aggregate Maximum Bit Rate (Aggregated Maximum Bit Rate, AMBR), magnitude of traffic flow template (Traffic Flow Template, TFT), control plane and user face address etc.) etc..Before the UE is not separated, these information are all to preserve, otherwise UE carry out tracing section updating (Tracking Area Update, TAU), service request ServiceRequest, When the behaviors such as attachment removal Detach, it can not just carry out handling, because second base station can not find the context of the UE, agreement (the IPInternet Protocol interconnected between its network is not just known, IP), it is connected PGW, it create those carryings, the message of its possible transmission can not all decrypt.In a communications system, occurs " context foundation " this saying often, what is referred in fact is exactly the foundation of context session, is primarily referred to as establishing connection between functional entity, is transmitted for information.For example RRC is established between UE and the functional entity of the second base station two, its communication link is exactly context.In second generation wireless communication technique (The 2nd Generation, 2G), 3rd generation mobile communication technology (3rd-Generation, context is primarily referred to as packet data protocol (Packet Data Protocol in 3G), PDP) context, refer to PDP activation gateway general packet radio service (General Packet Radio Service, GPRS the process of link) is established between supporting node (Gateway GPRS Support Node, GGSN).Context in LTE is primarily referred to as EPS bearer context, is the process for the connecting link established between UE and PGW.The foundation of context session includes four parts: encryption (for example, between UE and eNodeB) of eating dishes without rice or wine, terminal capability inquiry, signaling bear (SRB2) and Deta bearer (DRB).When terminal and mobile management unit (Mobility Management Entity, when being communicated between MME), need first to establish context session request, this is initiated by MME, conversation procedure is exactly the process for establishing carrying, including signaling bear (SRB2), Deta bearer (DRB)；Signaling bear, which has been built, can be carried out Signalling exchange, and Deta bearer has been built, so that it may send/received data packet.

IDLE state: if without Non-Access Stratum (Non-Access Stratum, NAS) signaling connection between UE and network, UE is at IDLE state.In IDLE state, UE can execute cell selection/reselection, or carry out PLMN selection.The UE of IDLE state is in access net (RadioAccess Network, it RAN is no UE context in), plane interface S1_MME connection both is controlled without S1 at this time, also without the S1_U connection of S1 interface in the user plane, wherein, S1_MME connection refers to evolved base station (evolved NodeB, eNB) (can refer to the second base station in embodiments of the present invention) to connect with the interface between MME, S1_U connection refers to that the interface between eNB and gateway (Serving GateWay, S-GW) connects.

It can be understood that, when link of the UE in the MCG is in dbjective state, the base station can configure the UE (being also possible to base station) so that link switching of the UE in the MCG is to activated state, when link of the UE in the MCG is in activated state, which can normally transmit various control face datas and user face data.

It can be that the base station is unilaterally arranged some parameters and realizes that link configuration of the UE in MCG is dbjective state by the base station, or hold consultation to realize with the UE in the base station；When the base station confirms successfully by the UE in MCG Link configuration be dbjective state after, response response can be sent to the UE and inform that the link configuration by the UE in MCG is for dbjective state, respond response it is of course also possible to not send to the UE.By the link configuration be dbjective state after, can save the transmission power of the UE on the link and receive power.

In a kind of optional scheme, step S603~S604 can also be performed after step S601~S602, step S603~S604's is described as follows.

Step S603: the base station obtains third signal quality and the second bandwidth.

In oneainstance, the third signal quality characterizes received signal quality of the terminal currently in the cell of the first base station, second bandwidth characterizes the current bandwidth of the first radio resource link, the mode that the base station (i.e. " the second base station ") obtains third signal quality is identical as the mode of the first signal quality is obtained, only the acquisition opportunity of two kinds of signal qualities is different, and third signal quality is that the link (i.e. the second radio resource link) between the UE and the second base station is in the signal quality obtained when dbjective state.The mode that base station obtains the second bandwidth is identical as the mode of the first bandwidth is obtained, only the acquisition opportunity of two kinds of bandwidth is different, which is that the link (i.e. the second radio resource link) between the UE and the second base station is in the bandwidth obtained when dbjective state.In another situation, the acquisition modes of the third signal quality and the second bandwidth are referred to obtain the acquisition modes of third signal quality and the second bandwidth in embodiment illustrated in fig. 4, after UE obtains third signal quality and the second bandwidth, the information of the information of the third signal quality and the second bandwidth is sent to the base station.

The embodiment of the present invention will also judge whether the third signal quality is less than fourth signal quality, and judge whether second bandwidth meets the demand of the business of carrying terminal.Optionally, fourth signal quality herein can be the terminal real-time signal quality (also can be described as the terminal real-time signal quality in the SCG) in second base station, it or is preset signal quality threshold, when the second signal quality of fourth signal quality and front herein is preset signal quality threshold, the second signal quality and fourth signal quality may it is equal may also be unequal.

In the event of any one situation in following situation, step S406 then can be performed, situation one: the base station determines that third signal quality of the UE in secondary cell group SCG is less than fourth signal quality, situation two: the base station determines that the SCG is unsatisfactory for carrying the demand of the current business of the UE, situation three, situation one and situation two are set up.

Step S604: the second radio resource link configuration is activated state active state by the base station.

Specifically, which by the second radio resource link (i.e. link of the UE in MCG) configures activated state and some parameters can unilaterally be arranged for the base station to realize, or holds consultation to realize with the UE in the base station；After the base station confirms that successfully the link configuration by the UE in MCG is activated state, a response response can be sent to inform that the link configuration by the UE in MCG is for activated state to the UE, it is of course also possible to not send response response to the UE.
