Family terminal (UE) separates, and realizes that the wireless resource management in units of cell eats dishes without rice or wine to need according to user
The purpose that appropriate Radio Resource is provided is sought, with multi-level integrated distribution (MLCD, Multi-level
Centralized and distributed) calculating of the mode to cell level and user terminal rank divides respectively
Class, on the basis of cloud big data computing capability feature is matched, realize the net of 5G customer-centric
Network target.

First embodiment
First embodiment of the invention provides a kind of method of allocation radio resource, and Fig. 2 is the embodiment of the present invention
Allocation radio resource method schematic flow sheet, as shown in Fig. 2 the flow includes：
Step 201：Base station obtains UE real-time position information, and the region that the base station is covered is included at least
Two cells.
When actually implementing, UE can obtain the positional information of itself in real time, and by the positional information of itself
Report is to corresponding base station, in this way, network side equipment such as base station can be to obtain UE real-time position information；
UE can obtain the positional information of itself using various ways, repeat no more here.
Here, the type of base station is not restricted, for example, base station can be the base station of 3G network, also may be used
To be the evolved base station (eNB, Evolved Node B) in 4G networks.
Step 202：The base station determines that the UE carries out the movement across cell based on the real-time position information
When, sent using the mac-layer protocol entity of itself to the mac-layer protocol entity of the UE and realize cell
The radio-resource-configuration signaling of switching.
It is understood that the overlay area of base station comprises at least two cells；Coverings of the UE in above-mentioned base station
When being moved in region, it can be moved in a cell, can also be from one of the overlay area of above-mentioned base station
Cell is moved to another cell.
In the prior art, when UE is moved to another cell from a cell, UE can be controlled to start
Cell switching flow, base station send cell handover command by RRC signaling to UE, make UE service small
Area switches to another cell from a cell, for example, at Long Term Evolution (LTE, Long Term Evolution)
In the cell handover scheme of system, the switching of UE to core net whole link is carried out using RRC signaling
Control；Here, the movement across cell that UE is carried out can be across small in the overlay area of same base station
The movement in area, it can also be the movement across cell carried out between two different base stations.
As can be seen that in existing cell handover scheme, the switching of UE to core net whole link exists
A set of signaling control is lower to be realized.
Relatively, in embodiments of the present invention, when UE is from the one small of the overlay area of same base station
When area is moved to another cell, base station utilizes MAC of the mac-layer protocol entity of itself to the UE
Layer protocol entity sends the radio-resource-configuration signaling for realizing cell switching, and keeps between base station and core net
Radio Link it is constant.
When UE from carried out between two different base stations across cell it is mobile when, i.e. UE is from base station
When cell is moved to the cell of another base station, using the mac-layer protocol entity of itself to the UE's
Mac-layer protocol entity sends the radio-resource-configuration signaling for realizing cell switching, and is sent out using RRC signaling
Play the switching to the Radio Link between base station and core net.
As can be seen that the embodiment of the present invention eats dishes without rice or wine to control by the quick of mac-layer protocol entity, drop significantly
The frequency of low UE triggerings handoff procedure, reduce the processing delay of space interface signaling, improve eat dishes without rice or wine can
By property, the complexity of signaling process is simplified.
In this step, the wireless money of cell switching is realized in the mac-layer protocol entity transmission to the UE
Before the configuration signal of source, the serving cell of the UE can also be configured；Further, can also match somebody with somebody for UE
Put the Radio Resource that above-mentioned serving cell can use, that is to say, that in the service configured of above-mentioned record
In the Radio Resource that cell can use, radio-resource-configuration is chosen to UE；For example, the area that base station is covered
Domain includes cell 1, cell 2 and cell 3, can be with before radio-resource-configuration signaling is sent to the UE
Cell 1, cell 2 or cell 3 are configured to UE serving cell；Can also by cell 1, cell 2 or
Radio-resource-configuration in cell 3 is to UE.
Here, the Radio Resource that serving cell can use can be the channel resource that serving cell can use
Etc..
It is understood that in the region that above-mentioned base station is covered, deposited between at least one cell and UE
At Radio Link (RL, Radio Link), the Radio Link between serving cell and UE can not only transmit
Signaling, user data can also be transmitted, and the Radio Link between other cells and UE can not transmit user
Data.
Specifically, the configuration UE of above-mentioned record serving cell includes：Obtain between UE and base station
Channel status data, the serving cell based on described channel status data configuration UE.
Further, the channel status data between UE and base station can include the area that UE is covered with base station
The channel status data between each cell in domain；Channel status data can be included in following parameter extremely
Few one kind：Channel condition information (CSI, Channel State Information), Reference Signal Received Power
(RSRP, Reference Signal Receiving Power), the signal intensity instruction received (RSSI,
Received Signal Strength Indication), Signal to Interference plus Noise Ratio (SINR, Signal to Interference plus
Noise Ratio), channel quality instruction (CQI, Channel Quality Indicator).
When actually implementing, UE can monitor the channel status data between UE and base station in real time, and to base
Station reports corresponding channel status data, and here, the channel status data between UE and base station can be UE
Corresponding various quality-monitoring parameters of eating dishes without rice or wine.
Here, the implementation of the serving cell to being configured UE based on acquired channel status data is not made
Limitation, for example, channel matter can be chosen in the Radio Link between acquired each cell and UE
Best Radio Link is measured, by the serving cell that cell configuration corresponding to the Radio Link of selection is UE.
In this step, the wireless money of cell switching is realized in the mac-layer protocol entity transmission to the UE
Before the configuration signal of source, each cell that Radio Link is established with the UE can also be formed swashing for UE
Set of cells living；As can be seen that the number of the cell of UE activation cell set is more than or equal to 1.
Illustrate the implementation that radio-resource-configuration signaling is sent to UE in two kinds of situation below.
The first situation：Be UE configuration serving cell UE activation cell set in.
Mac-layer protocol entity from base station to UE send radio-resource-configuration signaling be：Reconfigure described
UE and the Radio Link between the serving cell of the UE configurations signaling；Here, reconfigure described
The purpose of UE and the Radio Link between the serving cell of UE configurations is：Make the UE with for
Radio Link between the serving cell of the UE configurations can transmit signaling and user data.
For example, the region that base station is covered includes cell 1, cell 2 and cell 3, these three cells and UE
Between Radio Link be present, cell 1 is UE initial service cell, and cell 2 is configured for UE
Serving cell, it is to be understood that the Radio Link between cell 1 and UE can be used for transmit signaling and
User data, the Radio Link between cell 2 and UE cannot be used for transmitting user data；Now, base station
The signaling to the Radio Link between UE transmission reconfiguring cells 2 and UE is needed, so that cell 2 and UE
Between Radio Link can transmit signaling and user data.
Further, during the serving cell if UE configurations is gathered in UE activation cell, and match somebody with somebody for UE
The serving cell put not is UE initial service cell, then deletes UE's in the set of UE activation cell
Initial service cell, and then realize the renewal gathered UE activation cell.
For example, the region that base station is covered includes cell 1, cell 2 and cell 3, these three cells and UE
Between Radio Link be present, i.e. cell 1, cell 2 and cell 3 UE activation cell set in；
Area 1 is UE initial service cell, and cell 3 is the serving cell for UE configurations, at this time, it may be necessary to
Cell 1 is deleted in UE activation cell set.
Second of situation：In not gathering for the serving cell that UE is configured in UE activation cell.
Mac-layer protocol entity from base station to UE send radio-resource-configuration signaling be：Establish UE with for
The signaling of Radio Link between the serving cell of UE configurations；Establish UE and the serving cell for UE configurations
Between the purpose of Radio Link be：Make UE and the Radio Link between the serving cell of UE configurations
Signaling and user data can be transmitted.
For example, the region that base station is covered includes cell 1, cell 2 and cell 3, wherein, it is cell 1, small
Radio Link between area 2 and UE be present, Radio Link is not present between cell 3 and UE；Cell 1
For UE initial service cell, cell 3 is the serving cell for UE configurations, now, base station need to
UE sends the signaling for the Radio Link established between cell 3 and UE, so that the nothing between cell 3 and UE
Wired link can transmit signaling and user data.
It not is being UE for the serving cell that UE is configured it should be noted that for any one above-mentioned situation
Initial service cell, UE can be deleted and state Radio Link between UE initial service cell.
Step 203：UE determine itself to carry out across cell it is mobile when, utilize the mac-layer protocol of itself real
Body receives the radio-resource-configuration signaling for realizing cell switching.
Exemplarily, the radio-resource-configuration signaling that UE mac-layer protocol entity determines to receive is to match somebody with somebody again
When putting the signaling of the Radio Link between UE and the serving cell configured for UE, by UE with being configured for UE
Serving cell between radio link configuration be with following functions：Transmit signaling and user data；
The radio-resource-configuration signaling that UE mac-layer protocol entity determines to receive be establish UE with for
During the signaling of the Radio Link between the serving cell of UE configurations, the serving cell configured to UE sends foundation
The request of Radio Link, so that the Radio Link established can transmit signaling and user data.
In the embodiment of the present invention, base station to UE when sending radio-resource-configuration signaling, radio-resource-configuration
Signaling can be by wireless heterogeneous networks (RRC, Radio Resource Control) layer protocol entity of base station
Generation, can also be by media access control (MAC, Medium Access Control) layer protocol of base station
Entity generates, and illustrates separately below.
1) the rrc layer protocol entity generation radio-resource-configuration signaling of base station, the Radio Resource of generation is matched somebody with somebody
Confidence order is sent to the mac-layer protocol entity of base station, and afterwards, the mac-layer protocol entity of base station is to UE
Mac-layer protocol entity send radio-resource-configuration signaling, UE mac-layer protocol entity confirms to receive
After radio-resource-configuration signaling, radio-resource-configuration signaling is forwarded to UE rrc layer protocol entity, so as to
Realize the communication between base station and UE rrc layer protocol entity.
2) the mac-layer protocol entity of base station sends radio-resource-configuration to UE mac-layer protocol entity
Signaling, UE mac-layer protocol entity confirm to receive radio-resource-configuration signaling, realizes base station and UE
Communication between mac-layer protocol entity.
Further, after radio-resource-configuration signalings of the UE based on reception carries out resource distribution, if needed
UE is wanted to initiate uplink synchronous process, base station and UE mac-layer protocol entity is completed up same by interaction
Walk control process.
As can be seen that in the embodiment of the present invention, pass through the quick of base station and UE mac-layer protocol entity
Eat dishes without rice or wine to control, reduce signaling delay during allocation radio resource.
It should be noted that the area of coverage of another base station is moved to from the overlay area of a base station in UE
, it is necessary to start cell switching flow during domain；Cell switching flow can continue to use existing cell switching flow,
Here repeat no more.
Using the method for the allocation radio resource of first embodiment of the invention, base station obtains user terminal UE's
Real-time position information, the region that the base station is covered include at least two cells；The base station is based on described
