Description
Technical field
The present invention relates to long term evolution (LTE:Long Term Evolution) in communication system, dual link prothetic group station
(SeNB:Secondary eNB, also known as supplemented by evolved node B) preferably add problem, when especially in the presence of several candidate SeNB
It is preferred that adding problem.
Background technology
Dual link (DC:Dual Connectivity) make user equipment (UE:User Equipment) it can be with two base stations
(eNB:Evolved Node B, also known as evolved node B) it establishes and keeps connecting, wherein UE and master base station (MeNB:
Master Evolved Node B, also known as main evolved node B) control plane connection is established, and establish user plane with SeNB and connect
It connects.By dual link, control plane and user plane may be implemented to detach, so as to improve the performance of system, especially heterogeneous network
Performance.
The detailed process of SeNB additions is as follows：
1.MeNB determines that request SeNB is evolved Universal Mobile Communication System land radio access web radio access bearer
(E-RAB:Evolved Universal Mobile Telecommunications System Terrestrial Radio
Access Network Radio Access Bearer) distributing radio resource when, send the addition request of prothetic group station to SeNB
(SeNB Addition Request), and carry secondary cell group (SCG:Secondary Cell Group) configuration information (SCG-
), and instruction E-RAB features (E-RAB parameters, transport network layer (TNL Config:Transport Network Layer) address
Information).In addition, MeNB indicates that main plot configures (MCG in SCG-Config:Master Cell Group) and entire UE energy
Power.MeNB provides the measurement result of newest request addition SCG cells；
2. if the wireless resource management (RRM of SeNB:Radio Resource Management) module can receive resource
Request, it just distributes corresponding radio resource and corresponding transport network resources.SeNB triggers random access to execute SeNB
The synchronization of radio-resource-configuration.SeNB replys prothetic group station addition request-reply message (SeNB Addition Request to MeNB
Acknowledge), and the new radio resource of SCG in SCG-Config is carried；
3. if MeNB receives new configuration, MeNB sends wireless heterogeneous networks connection reconfiguration (RRC Connection to UE
Reconfiguration) message carries the new radio-resource-configuration of the SCG of corresponding SCG-Config；
The new configuration of 4.UE applications, and reply wireless heterogeneous networks connection reconfiguration and complete (RRC Connection
Reconfiguration Complete) message；
5.MeNB sends prothetic group station to SeNB and re-matches completion (SeNB Reconfiguraton Complete) message informing
SeNB UE have had successfully completed reconstitution process；
6. passing through random access (RA:Random Access) process, UE goes to the synchronization of SeNB；
7. being carried for SCG, MeNB takes action reduction since dual link activation is led according to the load characteristic of corresponding E-RAB
The service disconnection of cause.MeNB to SeNB transmit Sequence Number state transmit (SN Status Transfer) message, carry uplink and downlink
Packet Data Convergence Protocol (PDCP:Packet Data Convergence Protocol) sequence number and Hyper Frame Number (HFN:
Hyper Frame Number) state；
8. data forwarding.From gateway (SGW：Serving Gateway) data reach MeNB, then by MeNB
It is forwarded to SeNB；
9.MeNB is to mobility management entity (MME:Mobility Management Entity) send E-RAB modification refer to
Show (E-RAB Modification Indication) information updating user plane path；
Bearing modification is realized in 10.MME and SGW interactions；
11.SGW sends end of identification (End Marker) to MeNB and is grouped, and is forwarded to SeNB via MeNB；
12.MME sends E-RAB modifications to MeNB and confirms (E-RAB Modification Confirm) message.
However, current SeNB additions flow does not consider SeNB optimal selection problems.Especially when there are several candidate SeNB,
If the SeNB of selection addition is in higher load condition, the service quality that SeNB will be caused to be difficult to ensure E-RAB, to influence to use
It experiences at family.

After master base station collects one or more of prothetic group stations reply response messages, request-reply message is added from prothetic group station is replied
Prothetic group station secondary cell in, select the prothetic group station secondary cell of highest priority, then to UE send RRC connection reconfiguration message；
The prothetic group station transmission prothetic group station release request that master base station adds request-reply message to selected but reply prothetic group station disappears
Contexts of the breath release UE at the prothetic group station.
3. according to the method described in claim 2, it is characterized in that, the signal quality weighted average calculate, including：
Master base station obtains the weight of signal quality and resource status, obtains auxiliary to prothetic group station to poor descending from getting well according to signal quality
Cell be ranked up after serial number and according to resource utilization, ascending order is ranked up prothetic group station secondary cell from low to high
Then serial number afterwards calculates the average value of prothetic group station secondary cell according to the sum of products of weight and serial number.
4. according to the method described in claim 3, it is characterized in that, prothetic group station addition, further includes：
Master base station is when once only preferably a prothetic group station secondary cell is added from the prothetic group station secondary cell after priority ranking,
If the prothetic group station replys prothetic group station and adds refuse information, the next prothetic group station secondary cell of reselection initiates the addition of prothetic group station,
The rest may be inferred, until having attempted filtered all prothetic group stations secondary cell.
5. a kind of prothetic group station adding set of such as Claims 1 to 4 any claim the method, which is characterized in that including：
First receiving module, filtering module, sequence and selecting module, the first sending module；Wherein:
First receiving module receives measurement report and resource status update, by the measurement report and the money for master base station
The information that source state update carries is sent to the filtering module and sequence and selecting module；
Filtering module is filtered the candidate prothetic group station secondary cell of acquisition when adding prothetic group station for master base station；
Sequence and selecting module carry out priority ranking for master base station to the prothetic group station secondary cell for meeting condition after filtering, and
It selects one or more prothetic groups station secondary cell from high to low according to priority, the information of prothetic group station secondary cell is sent to institute
State the first sending module；
The information of first sending module, one or more prothetic group stations secondary cell for sending the sequence with selecting module is sent out
Target prothetic group station is given to realize that subsequent prothetic group station is added.
