System.
Background technique
In recent years, with global mobile communication portfolio sharp increase, the multiservice requirement of user and rapid growth
Data volume demand brings the increasing pressure to communication network.And the heterogeneous network of cell can then be effectively relieved it is above-mentioned
Pressure, while the seamless coverage of network can also be better achieved, to improve the data of spectrum efficiency and user and system
Handling capacity, so the heterogeneous network has also obtained more and more extensive deployment.
It is needed between cell the problem of frequent switching however, the heterogeneous network of cell also brings user.In order to
The load balancing of minizone is realized more flexiblely, and solves the problems, such as frequent switching, and 3GPP proposes dual link (Dual
Connectivity) this key technology.As shown in Figure 1, single user's terminal can use at least two in doubly-linked connection technology
The radio resource of a different network node passes through non-ideal return link (Non-ideal backhaul) phase between these nodes
Even, and each node can undertake different roles (master-slave relationship) in dual link.The wherein main base of control plane function
In master base station (MeNB) complete, user-plane function (i.e. data-transformation facility) by from base station (SeNB) complete or by master base station with
It is completed jointly from base station.
The specific implementation of doubly-linked connection technology is embodied in the design of control plane and user plane framework.It is flat for controlling

Specific embodiment
Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings and examples, how to apply to the present invention whereby
Technological means solves technical problem, and the realization process for reaching technical effect can fully understand and implement.It needs to illustrate
As long as not constituting conflict, each feature in each embodiment and each embodiment in the present invention can be combined with each other,
It is within the scope of the present invention to be formed by technical solution.
Meanwhile in the following description, for illustrative purposes and numerous specific details are set forth, to provide to of the invention real
Apply the thorough understanding of example.It will be apparent, however, to one skilled in the art, that the present invention can not have to tool here
Body details or described ad hoc fashion are implemented.
In addition, step shown in the flowchart of the accompanying drawings can be in the department of computer science of such as a group of computer-executable instructions
It is executed in system, although also, logical order is shown in flow charts, and it in some cases, can be to be different from herein
Sequence execute shown or described step.
In order to overcome the defect that existing dual link user terminal power consumption is big, capacity usage ratio is low, the present invention provides one
Kind new communication system is come so that dual link user terminal in the communication system is for master base station (i.e. MeNB) carrier wave and from base
The discontinuous reception operation of (i.e. SeNB) carrier wave of standing is coordinated, to reduce oneself power consumption, and improves capacity usage ratio.
The present invention is directed to make full use of the user plane construction characteristic of dual link, connect by SeNB of the MeNB to user terminal
The DRX operation for recording wave is controlled, to achieve the purpose that optimize the DRX operation of terminal, save final energy.
Fig. 4 shows the structural schematic diagram of communication system provided by the present embodiment.
As shown in figure 4, communication system provided by the present embodiment include master base station (i.e. MeNB), from base station (SeNB) and use
Family terminal (i.e. UE).Wherein, it is not directly connected core net for user-plane protocol framework 3C, SeNB, received data
It is to be forwarded by MeNB, therefore MeNB is completely known for the downlink data of SeNB.The present invention is to utilize above-mentioned spy
Point optimizes come the DRX operation to user terminal.
For the user terminal of dual link, need to receive data on MeNB carrier wave and SeNB carrier wave simultaneously, therefore need
Want two sets of independent DRX mechanisms.User terminal is similar with the DRX in LTE for the reception mode of MeNB carrier wave, that is, uses short week
The mode of phase and long period cooperation is realized to the reception of MeNB carrier wave, is not just repeated herein.
However for SeNB carrier wave, in the present embodiment, user terminal carries SeNB during receiving the carrier wave
The DRX state of wave at least increases one kind, the state be completely closed state (in the present embodiment, first state i.e. complete
Closed state).When SeNB is there are when downlink data, user terminal is in the second state, and (in the present embodiment, the second state includes swashing
State living and dormant state).In this state, user terminal connects the receive process from base station carrier with to master base station carrier wave
Receipts process is similar.And when SeNB does not have data arrival, user terminal can completely close it from base station carrier receiver, in this way
User terminal is also with regard to no longer monitoring from base station carrier, to further save final energy.
Fig. 5 shows the flow chart that user terminal is switched to first state by the second state.
As shown in figure 5, similar with DRX cycle in LTE, user terminal is using short when user terminal is in the second state
The mode of period and long period cooperation is monitored from base station carrier.
In step S501, master base station continues to monitor the downlink data from base station, and judges in step S502 from base station
Whether the transmission of downlink data is completed.For user plane framework 3C, since the data from base station are turned by master base station completely
Hair, therefore master base station is completely known to the data from base station.It therefore also can be using master base station to the DRX of user terminal
Operation is controlled, and carrys out reception of the controlling terminal progress from base station carrier with this.In the present embodiment, master base station passes through PDCP layers
Confirmation message judges whether the downlink data from base station has been sent completely.Certainly, in the other embodiment of the present invention
In, master base station can also judge the transmission that downlink data whether is completed from base station by other rational methods, and the present invention is unlimited
In this.
If master base station judges the transmission for completing downlink data from base station, in step S503, master base station will
The first control instruction is sent to user terminal.If master base station judges the transmission for not completing downlink data from base station,
At this time by return step S502 to continue to monitor the downlink data from base station.
After master base station is learnt by PDCP layers of confirmation message to be sent completely from the downlink data of base station, this
When user terminal be also no longer needed for from from base station receive data.Therefore, in order to further save the energy of user terminal, main base
It stands and just needs to notify user terminal come so that user terminal completely closes (i.e. to from the reception of base station carrier by RRC signaling
First state is switched to from base station).For this purpose, introducing new RRC signaling (i.e. the first control instruction), the letter in the present embodiment
Enable is that (in the present embodiment, which can be from base station data end of transmission mark for RRC-SeNBReceptionMuting instruction
Know).
After user terminal receives the first control instruction that master base station is sent, judge in step S504 inside it from
Whether base station carrier re-transmission timer is currently running.If be currently running at this time from base station carrier re-transmission timer, user terminal
Then continue to monitor from base station carrier in step S505, until the re-transmission timer stops.It is retransmitted from base station carrier
After timer stops, user terminal stops in step S506 to the monitoring (being switched to first state) from base station carrier.And
If user terminal is judged do not running from base station carrier re-transmission timer at that time, then user is whole in step S504
End executes step S506 directly then to stop to the monitoring from base station carrier.
User terminal, which is closed in step S506 from base station carrier receiver, to be stopped to the monitoring from base station carrier.So
And in the present embodiment, user terminal can keep counting from base station DRX for its inside while closing from base station carrier receiver
When device operate normally, can maintain traditional DRX cycle constant in this way.
Certainly, in other embodiments of the invention, user terminal can also be stopped using other rational methods to from
The monitoring of base station carrier, the invention is not limited thereto.
In the present embodiment, master base station is controlled user terminal by the first control instruction and closes it from base station carrier reception
Machine.However, master base station can't give " receiver of user terminal has been switched off " this state notifying from base station.It in this way can be with
It reduces master base station and is born from the Signalling exchange between base station.
Master base station to the DRX of user terminal operation control for being transparent for from base station, so master base station does not need
By backhaul link notice, from base station, it adjusts the DRX cycle of user terminal.However for user terminal,
It needs to remain consistent constant from base station DRX parameter configuration.Therefore, compared to existing user terminal, the present embodiment is provided
User terminal just enter a kind of new slave base station carrier reception state (i.e. first state) in this state.
As can be seen that the present invention takes full advantage of the data forwarding feature of user plane framework from foregoing description, pass through
Master base station carries out switch operation to the slave base station carrier receiver of user terminal, so that after being sent from base station down data
User terminal can be closed from base station carrier receiver, to further reduced the power consumption of user terminal.
Meanwhile in technical solution provided by the present invention, there is no being made a change to traditional DRX timer, make in this way
It is fully transparent that the DRX for obtaining user terminal, which is adjusted for from base station, to effectively save while reducing signaling traffic load
The energy of user terminal is saved.
Fig. 6 shows the flow chart that user terminal in the present embodiment is switched to the second state by first state.
As shown in fig. 6, the slave base station carrier receiver of user terminal, which is in, closes shape when not having downlink data from base station
State is in normal operating condition from base station DRX timer.For user plane framework 3C, in step s 601, main base
Station continues to monitor the downlink data from base station, and judges from base station in step S602 with the presence or absence of downlink data.
In the present embodiment, master base station is forwarded to by its corresponding port (such as X2 mouthfuls) from base by judging whether there is data
It stands to judge from base station with the presence or absence of downlink data.If there is data are forwarded to from the corresponding port of master base station from base station, then
At this moment master base station can judge that there are downlink datas from base station at this time；Otherwise can judge to be not present from base station at this time
Downlink data.
It should be noted that in other embodiments of the invention, master base station can also be sentenced by other rational methods
Disconnected to whether there is downlink data from base station, the invention is not limited thereto.
When master base station hair available data is forwarded to by corresponding port (such as X2 mouthfuls) from base station, i.e., in the presence of base station
When row data, user terminal just needs to receive the downlink data transmitted from base station.Therefore, master base station just needs to control user terminal
It will be opened from base station carrier receiver, in case carrying out the reception of downlink data.
Specifically, in the present embodiment, when master base station discovery has data forwarding to from base station, master base station will be in step S603
It is middle to send the second control instruction to user terminal to notify user terminal to be ready for the reception from base station down data.Wherein,
Second control instruction is the RRC-SeNBReceptionUnMuting signaling in RRC signaling.Certainly, in other realities of the invention
It applies in example, the second control instruction can also be other reasonable signalings, and the invention is not limited thereto.
In step s 604, it after user terminal receives the second control instruction that master base station is sent, can open from base station
Carrier receiver is hence into normally from the DRX cycle of base station carrier (being switched to the second state by first state).
It should be noted that in the present embodiment, user terminal after receiving the second control instruction that master base station is sent,
Its internal slave base station carrier receiver might not be opened immediately, but restored from first state, and according to it is known from
Base station parameters carry out traditional DRX operation.After timer enters from the state that base station carrier receiver needs to open, use
Family terminal is just opened from base station carrier receiver and carries out the reception from base station down data.
It is pointed out that above-mentioned " RRC-SeNBReceptionMuting signaling " and " RRC-
SeNBReceptionUnMuting signaling " is the function for describing related protocol, is not corresponded in actual standard agreement
Specific message name.
The present invention is further described below in conjunction with the communication system shown in Fig. 7.
In communication system shown in Fig. 7, user terminal UE1, which is that double hairs are double, receives terminals, both with master base station (i.e. MeNB1)
Connection, also connect with from base station (i.e. SeNB1), and master base station and between base station progress dual link operation.User terminal UE2
It is traditional terminal with user terminal UE3, they can only keep connecting with base station, wherein user terminal UE2 is only and from base
It stands connection, user terminal UE3 is only connect with master base station, the two user terminals are operated without dual link.
When user terminal UE1 is located within the scope of macrocell and cell Double mulch, user terminal UE1 uses user face
3C scheme keeps dual link with MeNB1 and SeNB1.The downlink data for being sent to user terminal UE1 is sent to by core net
MeNB1, MeNB1 carry out radio bearer separation after PDCP layers of processing.Part PDCP PDU is sent out by MeNB1 by Xn interface
Air interface transmission is carried out to SeNB1 and by SeNB1, remaining PDCP PDU is by MeNB1 by eating dishes without rice or wine to be transmitted.
After MeNB1 learns that the downlink data of SeNB1 is all successfully transmitted by PDCP layers of confirmation message, it can lead to
It crosses and sends RRC-SeNBReceptionMuting signaling to user terminal UE1 to notify user terminal UE1 to close from base station carrier
Receiver.After MeNB1 has found that new downlink data reaches SeNB1, RRC- can be sent to user terminal UE1
SeNBReceptionUnMuting signaling notifies the user terminal UE1 to restore traditional DRX operation.
In above process, user terminal UE1 is similar with LTE to the DRX process flow of master base station carrier wave, to from base station
The DRX adjustment of carrier wave is then controlled by master base station.
Specifically, user terminal UE1 is identical for the condition run under master base station carrier wave and LTE.That is, detection current subframe
It whether is subframe that DRX cycle starts, if so, user terminal UE1 then begins listening for the PDCCH channel of master base station.
And for sending RRC-SeNBReceptionUnMuting letter from master base station to user terminal UE1 from base station carrier
It enables so that user terminal UE1 is for entering normal DRX cycle from the reception of base station carrier.In normal DRX cycle, user is whole
End UE1 can detect whether current subframe is subframe that DRX cycle starts.If so, user terminal UE1 is then begun listening for from base station
The PDCCH channel of carrier wave is executed and is operated to DRX as master base station carrier-class.
It is identical with traditional LTE for master base station carrier wave, if user terminal UE1 receives DRX Command MAC
CE instruction, user terminal then enter dormant state and (if re-transmission timer is currently running, wait until to enter after re-transmission timer stops
Dormant state) and continue to DRX cycle progress discontinuous reception.For from base station carrier, if user terminal UE1 is received
DRX Command MAC CE then enters dormant state (if re-transmission timer is currently running, after waiting until that re-transmission timer stops
Into dormant state) and continue to DRX cycle progress discontinuous reception.And when user terminal UE1 receives master base station transmission
RRC-SeNBReceptionMuting signaling when, user terminal UE1, which is then completely closed from base station carrier receiver, enters the
One state.
When user terminal UE1 from the reception of base station carrier to completely closing, whenever SeNB1 has downlink data (downlink
When data by MeNB1 by X2 mouthfuls of forwardings come), MeNB1 is by corresponding RRC signaling (i.e. RRC-
SeNBReceptionUnMuting it is sent to user UE1) to prompt UE1 to start receiving data from base station carrier.At this point, with
(but user terminal UE1 is to from base station carrier to normal DRX cycle is initially entered from the reception of base station carrier for family terminal UE 1
Reception not necessarily immediately enters state of activation), and the period is configured to period assignment known to SeNB1.
Fig. 8 shows master base station carrier wave in the present embodiment (i.e. MeNB carrier wave) and the week from base station carrier (i.e. SeNB carrier wave)
Phase configuration.
As shown in figure 8, MeNB1 learns that the downlink data of SeNB1 is sent by PDCP layers of confirmation message at position 1
It finishes, MeNB1 sends from the base station data end of transmission to user terminal UE1 and identifies, and user terminal UE1 can be by it from base station carrier
Receiver is switched to completely closed state.
At position 2, MeNB1 forwards data to SeNB1 by X2 mouthfuls, and SeNB1 has downlink data to need to send, simultaneously
MeNB1 sends the downlink transfer since base station to user terminal UE1 and identifies.User terminal UE1 receive start after the mark into
Enter normal DRX operation (it should be noted that at this time user terminal UE1 for the reception from base station carrier not necessarily at once into
Enter state of activation).MeNB1 is significantly larger than MeNB1 to the time delay of SeNB1 forwarding data and sends dependent instruction to user terminal UE1
Time delay, can guarantee in this way SeNB1 to user terminal UE1 send data when, user terminal UE1 has been prepared for receiving number
According to (i.e. user terminal UE1 comes into normal DRX operation).
At position 3, MeNB1 sends DRX Command MAC CE instruction to user UE1, so that UE1 pairs of user terminal
The reception of master base station carrier wave enters discontinuous receiving state, and master base station carrier wave continues normal DRX operation later.
Similar with the operation of position 3 at position 4, SeNB1 sends DRX Command MAC CE to user terminal UE1
Instruction so that user terminal UE1 enters discontinuous receiving state to from the reception of base station carrier, later from base station carrier continue into
The normal DRX operation of row.
As can be seen that the present invention takes full advantage of the data forwarding feature of user plane framework from foregoing description, pass through
Master base station carries out switch operation to the slave base station carrier receiver of user terminal, so that after being sent from base station down data
User terminal can be closed from base station carrier receiver, to further reduced the power consumption of user terminal.
Meanwhile in technical solution provided by the present invention, there is no being made a change to traditional DRX timer, make in this way
It is fully transparent that the DRX for obtaining user terminal, which is adjusted for from base station, to effectively save while reducing signaling traffic load
The energy of user terminal is saved.
