Amount）By UE is handled in downlink.Processing be in order to filter out the defect that rapid fading effect and layer 1 are measured/estimated, this
A little processing, measurement will be reported to base station with periodically or in the form of event triggering.Therefore switching starts based on handover measurement
Processing, if switching condition is met, the Target cell of targeted sites covering is small by the service as UE under UE assistance
Area.It should be noted that website is physical equipment, cell is concept in logic, and a general website can have 3 or 6
Cell（Sector）.If 3 cells, each sector is probably 120 degree of angle.To cell-of-origin and the overlapping cell of Target cell
Part, if targeted sites are big in the signal intensity of the cell portion, the cell portion is Target cell, otherwise the cell portion
It is divided into cell-of-origin.
During handover decisions, targeted sites will be entered according to information such as the loading conditions and UE types of service of current area
Row acceptance judging, if the load of Target cell exceedes thresholding, the switching admission control algorithm of Target cell can typically refuse source
The handover request of website, this can cause handoff failure or cause UE call drops.
In hand-off execution process, UE needs to discharge the radio resource control of cell-of-origin（Radio Resource
Control, RRC）Connection, searches for the signal of Target cell, and detects the synchronizing channel of Target cell, performs synchronous and connects at random

During equipment UE switches to targeted sites from Source Site, consulted to initiate website, shunting targeted sites and porthole bridge by shunting
According to shunting negotiation is carried out between bag repeater station, to adjust transmission shunt ratio and transmission of the UE data in shunting targeted sites
Dispatching priority, realizes the purpose of lifting performance of handoffs, details are as follows：
1st, shunting consult to initiate website according to the business data packet of user equipment (UE) in the service transmission rate of Source Site and
The expection UE service transmission rates of targeted sites, calculate the business transmission for the business data packet for needing to be diverted to shunting targeted sites
Speed.
2nd, shunting negotiation initiation website sends to carry in request message, the request message and is diverted to shunting targeted sites
Shunt the requirement of the service transmission rate of the business data packet of targeted sites.
Wherein, it can also include ensureing speed in the request message.It is to ensure the business transmission of Consumer's Experience to ensure speed
Minimum-rate, such as speech business or video call service, all secure rate requirement.
In addition, shunting targeted sites can also be carried in request message to need increased maximum traffic transmission rate, divides
Flow type of service and transmitting and scheduling priority that targeted sites need to support.
Wherein, maximum traffic transmission rate is, in order to avoid business takes excessive Internet resources, therefore to limit
Shunt the maximum traffic transmission rate of targeted sites.Such as one user downloads high-definition movie with FTP, can pass through maximum traffic
Transmission rate is limited, to avoid this business from excessively taking Internet resources so that the service of other users cannot be protected
Card.
Shunting the type of service of targeted sites support includes such as speech business, video traffic etc., and dispatching algorithm is according to industry
Service type determines the scheduling requirement of business, such as speech business may use semi-persistent scheduling etc..
Transmitting and scheduling priority is that the number of times for dispatching user to website is directly proportional.Even if it is known that different user is used
Be that above-mentioned several indexs such as the guarantee speed between identical business, and their business are identicals, but be due to user
Between history dispatch situation it is different, some scheduling it is many, what some were dispatched lacks, and some signal qualitys of eating dishes without rice or wine are good, some letters of eating dishes without rice or wine
It is number of poor quality, so in order to ensure the justice between user, be according to its transmitting and scheduling priority when being scheduled to user
It is scheduled.This priority is exactly a numeral, such as just starts, the initial value of the transmitting and scheduling priority of each user
It is 1, rear party A-subscriber is scheduled often, and the number of times that party B-subscriber is scheduled is few, then the transmitting and scheduling priority of party A-subscriber is exactly
1.2, the transmitting and scheduling priority of party B-subscriber is 0.9 etc..
3rd, the load for shunting targeted sites according to itself, surplus resources, whether calculating, which can meet the request, disappears
The requirement for the service transmission rate that breath includes.
4th, if it is satisfied, then shunting targeted sites, which send response success message to the shunting, consults initiation website.
5th, the shunting negotiation initiates website and sends packet shunting forwarding instruction message to streamed data bag repeater station.
6th, UE business data packet is diverted to by the shunting targeted sites, the instruction message according to the instruction message
The middle business data packet for indicating to branch to the shunting targeted sites that carries is in the service transmission rate for shunting targeted sites.
Wherein, the data for the UE for indicating to branch to the shunting targeted sites can also be carried in message is indicated described
Shunt guarantee speed, maximum traffic transmission rate, type of service, maximum delay and the shunt ratio of targeted sites.
Wherein, with above-mentioned guarantee speed, maximum delay is also an important indicator, such as QQ classes are to delay requirement
Second-time, and the time delay of the permission such as email can with longer, can minute level time delay.
Streamed data bag repeater station can be forwarded the business data packet of user according to shunt ratio.Such as one
The packet of user has 2M altogether, and shunt ratio is 40% to arrive micro- station, then 0.8M packet just is diverted into micro- station.
In above-mentioned shunting negotiations process, it is assumed that have suitable shunting targeted sites（That is UE is in its coverage）, tool
Body shunting can shunt means accordingly according to its target selection.Certainly, if UE is not shunted before switching, that is in order to reach
Improve the purpose of data transmission performance above by shunting, then need to start shunting.
Additionally, it is preferred that, before step 6 execution, in addition it is also necessary to shunt targeted sites and set up the carryings of all business of UE and match somebody with somebody
Put.
Such as, in the scene 1 shown in Fig. 1, the data transfers of UE before handover be by macro station 1 and it is micro- station 3, and
In handoff procedure, the data transmission channel between UE and macro station 1 is interrupted（Because UE will search for the signal of macro station 2 with macro station 2 to enter
Row connection is set up）, so now data transfer all between network and UE is transmitted by shunting targeted sites, this is just
It is required that shunting targeted sites need the configuration information of all service bearers of UE.And before handover, targeted sites may be shunted
UE partial service processing parameter configuration is only configured with, such as UE there are 2 business of voice-and-data, and high-level signaling and speech business exist
LTE macro stations are transmitted, and data service realizes LTE+Wifi shunting in Wifi station transmissions.Under this scene, LTE macro stations only have
Signaling and the configuration information of speech business, Wifi websites only have the configuration information of data service.And to realize and make Wifi websites
Shunting is realized for target shunting website, then when needing the UE to switch between LTE macro stations, signaling and voice industry are set up on Wifi websites
The carrying configuration of business.
It should be noted that UE is divided into handoff preparation phase in the handoff procedure that targeted sites are switched to from Source Site, cut
Change execution stage and switching completion stage.
