To keep the technical principle, feature and technical effect of technical scheme clearer, below in conjunction with specific reality
Example is applied technical scheme is described in detail.
In dual link network, MeNB and the at most configurable serving cells of SeNB total are 5, a PCell, a master
Auxiliary serving cell (PSCell) and 3 SCell.Wherein, PCell is allocated to UE by macro base station, and PSCell is allocated to by micro-base station
UE, is functionally similar to PCell, and SCell is allocated to UE by macro base station or micro-base station.
The application indexes SCellIndex for how dual link network distributes auxiliary serving cell in MeNB and SeNB, mentions
Several schemes below out:
Embodiment one: it by MeNB distribution auxiliary serving cell index, is first added after distribution auxiliary serving cell index corresponding auxiliary
Serving cell.
MeNB judgement user needs using doubly-linked connection technology, then sends asking for addition serving cell to the SeNB for the condition that meets
Message is sought, in MeNB request SeNB addition serving cell, instruction will add the SCellIndex of serving cell.After SeNB judgement
By the cell ID for the condition that meets it is the SCellIndex of MeNB instruction, and its wireless resource configuration is fed back into MeNB.
The signaling process of the embodiment of the present application one is as shown in Fig. 2, include the following steps:
Step 201: macro base station judgement service bearer needs to increase micro-base station local resource, and macro base station is sent to micro-base station
SeNB addition request (SeNB Addition Request), wherein carrying service bearer characterisitic parameter.The service bearer characteristic
Parameter includes E-RAB parameter, transport network layer address information, the wireless resource information of macro base station and the user in corresponding user face
Equipment wireless capability.In the embodiment of the present application, needs carrying to distribute in the request message that macro base station is sent to micro-base station and add
The secondary cell index value (SCellIndex) of the micro-base station cell added.
Step 202: the micro-base station cell radio resource that micro-base station is added according to service bearer characterisitic parameter distribution, and
The secondary cell index value of macro base station distribution is applied to the micro-base station cell of addition.Addition request confirmation response is sent to macro base station
Message (SeNB Addition Request Acknowledge).
Step 203: macro base station sends RRC connection reconfiguration to UE and sets message (RRC Connection
Reconfiguration), triggering UE applies new radio-resource-configuration.
Step 204:UE sends radio-resource-configuration to macro base station and completes (RRC Connection Reconfiguration
Complete) message is fed back and successfully uses new configuration.
Step 205: macro base station reconfigures to micro-base station transmission and completes message (SeNB Reconfiguration
Complete), feedback UE has successfully used new configuration.
Step 206:UE executes synchronizing process to the micro-base station cell of addition.
Step 207-208: data forwarding operation is carried out between macro base station and micro-base station.
Step 219 is to step 212: if to establish the carrying of secondary cell group, carrying out path integration process.
Embodiment two: by MeNB distribution auxiliary serving cell index, auxiliary serving cell rope is distributed after first adding auxiliary serving cell
Draw.
MeNB judgement user needs using doubly-linked connection technology, then sends asking for addition serving cell to the SeNB for the condition that meets
Message is sought, the cell radio resource configuration information for the condition that meets is fed back into MeNB after SeNB judgement.
Embodiment two proposes that MeNB receives the addition response message of SeNB transmission, and needing to parse SeNB is dual link user
The service cell information of configuration, and distribute corresponding SCellIndex to these serving cells, then MeNB by eat dishes without rice or wine by
The serving cell resource information of SeNB configuration is handed down to dual link user, while the distribution that serving cell affiliated under SeNB is indexed
As a result SeNB is fed back to by Xn mouthfuls.
Due to discussing determining signaling process at present, MeNB is not needed after receiving the signaling message of SeNB addition serving cell
Feedback, therefore, embodiment two propose that one feedback message of increase in existing procedure, instruction SeNB are dual link user configuration mark
Know the SCellIndex that the serving cell for being cellIdentification distributes.
The signaling process of the embodiment of the present application two is as shown in figure 3, include the following steps:
Step 301: macro base station determines to increase micro-base station local resource, sends SeNB addition to micro-base station and request (SeNB
Addition Request), wherein carrying service bearer characterisitic parameter.The service bearer characterisitic parameter includes E-RAB parameter,
Transport network layer address information, the wireless resource information of macro base station and the user equipment wireless capability in corresponding user face.
Step 302: the radio resource for the micro-base station cell that micro-base station is added according to service bearer characterisitic parameter distribution,
Addition confirmation response message is sent to macro base station, the mark of the micro-base station cell of addition is carried in message.
Step 303: macro base station is the micro-base station cell distribution secondary cell index value of addition, and sends addition to micro-base station and answer
It answers message (SeNB Addition Response), the secondary cell index of the micro-base station cell distribution for addition is carried in message
Value.The secondary cell index value is applied to the micro-base station cell of addition by micro-base station.
Step 304: macro base station sends RRC connection reconfiguration to UE and sets message (RRC
ConnectionReconfiguration), triggering UE applies new radio-resource-configuration.
Step 305:UE sends radio-resource-configuration to macro base station and completes (RRC
ConnectionReconfigurationComplete) message is fed back and successfully uses new configuration.
Step 306: macro base station reconfigures to micro-base station transmission and completes message (SeNB Reconfiguration
Complete), feedback UE has successfully used new configuration.
Step 307:UE executes synchronizing process to the micro-base station cell of addition.
Step 308-309: data forwarding operation is carried out between macro base station and micro-base station.
Step 310 is to step 313: if to establish the carrying of secondary cell group, carrying out path integration process.
Embodiment three: MeNB and SeNB coordinated allocation serving cell index.
Since the at most configurable serving cells of MeNB and the SeNB total in dual link network being dual link user service are 5
A, auxiliary serving cell index range is still (1-7).The embodiment of the present application three proposes: MeNB is in the range according to from small to large
Be arranged in order and belong to the auxiliary serving cell of MeNB, SeNB then belongs to the serving cell of SeNB according to being arranged in order from big to small
(including PSCell and auxiliary serving cell).
According to embodiment three, process as shown in Figure 2 or Figure 3 is modified as follows: MeNB is sent to SeNB
SCellIndex, which is replaced with, carries a numerical value n, and being used to indicate the configurable cell number of SeNB is n；SeNB is used for dual link
When family configures serving cell, serving cell index is distributed from big to small according to the sequence from 7 to 7-n, as MeNB tells SeNB can
Serving cell can be identified if SeNB can be 2 serving cells of dual link user configuration with 2 serving cells
SCellIndex is 7 and 6.
The foregoing is merely the preferred embodiments of the application, not to limit the protection scope of the application, it is all
Within the spirit and principle of technical scheme, any modification, equivalent substitution, improvement and etc. done should be included in this Shen
Within the scope of please protecting.
