Method for handover control and system, user terminal, the network equipment
Technical field
The present invention relates to the communication technology, especially method for handover control and system, user terminal, the network equipment.
Background technology
TD SDMA(Time Division-Synchronous Code Division Multiple
Access, hereinafter referred to as:TD-SCDMA)It is a kind of technical standard of third generation radio communication.TD-SCDMA high-speed uplinks
Packet is accessed(High Speed Uplink Packet Access, hereinafter referred to as:HSUPA)It is the evolution of TD-SCDMA standards
Standard, also referred to as TD-HSUPA, or directly it is referred to as HSUPA.At present, TD-HSUPA business has obtained extensive popularization and application.
The characteristic of up-high speed business necessarily brings the ratio of network side total received power and noise power(Raise over
Terminal, hereinafter referred to as:ROT)With reception total bandwidth power(Received total wide band power, below letter
Claim:RTWP)Lifting, especially in user equipment(User Equipment, hereinafter referred to as:UE)In Serving cell(Also referred to as:
This cell)During edge, the problem is more common and influences larger, and the interference to adjacent cell also becomes apparent.
According to existing TD-SCDMA standards specify, UE it is closest once receive network side distributing authentication information when
Between exceed preset authorization interval T_WAIT after, by enhanced dedicated(Enhanced Dedicated
Transport Channel, hereinafter referred to as:E-DCH)Stochastic accessing ascending control channel(E-DCH Random Access
Uplink Control Channel, hereinafter referred to as:E-RUCCH)Schedule information is sent to network side(SI), the SI includes UE
Serving cell and adjacent cell path loss(Serving and Neighbour Cell Pathloss, hereinafter referred to as:SNPL)Letter
Breath.Afterwards, UE opens a timer and carries out timing according to preset period of time T-RUCCH, if not connect in preset period of time T-RUCCH
The authorization message that network side is issued based on this SI for reporting is received, UE needs to be sent to network side again by E-RUCCH
SI, if UE has sent N_RUCCH SI and has been not received by the authorization message that network side is issued, UE needs to initiate former to network side
Cause(cause)It is Radio Link Failure(radio link failure)Cell update(cell update)Process.
There is the difference of essence in influence of the up-high speed business with downstream data traffic to communication system.Downlink business speed
Bottleneck be primarily limited to channel resource, and the bottleneck of uplink service speed is in addition to being limited to channel resource, also by up
The factor limitation of AF panel.Due to code check high correspondence high power, when the uplink power of some UE increases, this UE pairs
The interference of other UE will also increase, therefore also just cause to whole communication system, including this cell and adjacent cell communication system
Interference increases.In order to reduce the lifting of RTWP, so as to reduce the annoyance level between cell, one kind side for taking in the prior art
Formula is that control makes network side that the mandate that authorize or will be issued to UE is not scheduled to UE and believe to the scheduling authorization power of UE
Authorization power in breath is reduced to minimum.However, the reduction to the authorization power of UE limits UE uplink power, so as to limit
The code check of Traffic Channel has been made, service feature has been reduced, i.e.,:Reduce handling capacity.
Because TD-HSUPA does not support soft handover, the reverse link traffic channel power of UE can only be controlled by this cell.Due to
SNPL information is reported by SI, is called time in SNPL information and is received the limitation of SI transmission frequency, by preset period of time T-RUCCH
Determined with preset authorization interval T_WAIT.It is existing for the interference time between the lifting duration, the reduction cell that reduce RTWP
Having a kind of mode taken in technology is, the scheduling authorization frequency to UE is controlled by controlling the transmission frequency of SI.If however, SI
Transmission frequency it is too high, the transmission opportunity of excessive effectively uplink business data can be taken, influence some small data business or week
The time delay of the data service of phase property transmission.And the transmission frequency of SI is too low, it is easily caused UE and changes field faster in Traffic Channel
Under scape, for example, when UE is located at cell edge, excessively frequently cell is initiated more when need not initiate cell updating course
New process, so as to cell that is excessively frequent during causing UE in the foundation of up-high speed business or carrying out and there is no need more
New process, has had a strong impact on quality of service, causes the steep drop of service rate, and can seriously improve cutting off rate.
Therefore, prior art suppresses inter-cell interference to the scheduling authorization power of UE by controlling with scheduling authorization frequency
Degree and the mode of interference time, reduce service feature, and cannot take into account uplink business data transmission delay and prevent
In the problem of cell updating course that is frequent and there is no need.

At present, UE can will carry the SI of SNPL information and periodically be sent to the network equipment, and this sends cycle by net
Network device configuration, sends that period assignment is big to be conducive to more sending out scheduling resource and dispatcher for valid data
Send.If for example, the transmission cycle of configuration SI is every 8 subframes sends once, then just representing in every 8 subframes necessarily has one
Subframe sends SI data, and the send opportunity of valid data is exactly remaining that 7 subframes.In other words, if the transmission week of SI
Phase is N, then the transmission time accounting of valid data is just 1- (1/N), therefore, N is bigger, and the transmission opportunity of valid data gets over
It is many, but it is unfavorable for timely tracking of the network equipment to SNPL information.If conversely, transmission period assignment is small, namely SI sends
Frequency is excessive, can influence the timely transmission of new data or the timely re-transmission of legacy data, especially in the limiting case, it may appear that every
It is secondary to have arrived certain hybrid automatic repeat request process(HARQ process)Moment be exactly just SI delivery time, then this
Individual process(process)The eternal hair of re-transmission data do not go out.
The embodiment of the present invention considers Special Influence of the up-high speed business to GSM, and SNPL is applied into base
Reported above in the measurement of event triggering, in uplink service especially up-high speed business, for example, in TD-HSUPA business,
It is lasting too small when SNPL values are detected, that is, when continuing excessive to adjacent cell interference, fast and effectively cut using a kind of new
The mode of mode and non-controlling scheduling authorization power and scheduling authorization frequency is changed, by being in time switched to the uplink service on UE
Suitable cell and frequency suppress inter-cell interference degree and interference time, without by way of lost traffic performance come
Control RTWP, had both effectively reduced interference of the UE in Serving cell adjacent edges to adjacent cell, and need not pass through cell update side
Formula and forbid UE send business datum or reduce UE send business datum amount mode, so as to effectively prevent cutting off rate improve
Dropped suddenly with service rate.In time, inter-cell interference degree and interference time are effectively inhibited, up-high speed business is improve
Cell edge service feature under pattern, and avoid the uplink business data transmission delay increase for thus bringing or excessively frequency
Cell updating course that is numerous and there is no need.

Each SNPL values that hair Delay is detected in the corresponding time period are respectively less than the first default SNPL threshold values, are set from UE to network
Preparation plays 6H event measurement report message, to be based on the additional survey of same frequency in 6H event measurement report message by the network equipment
Uplink service on UE is switched to suitable cell and frequency by amount object information with alien frequencies additional measurement information.The present invention
6H events are fixed as reporting based on event triggering in embodiment, and measurement that aperiodicity is reported control.In view of UE meetings
The SI for carrying SNPL is periodically sent to the network equipment, therefore, can be without herein based on periodically measurement SI reporting
Consider.The network equipment, such as base station, in the various measurement control messages that UE is issued, by a measurement reporting types
(measurement reportting mode)Information unit come represent one measurement Control Cooling, which kind of mode of UE informed
Reported.Reporting schemes therein only have two kinds, and one kind is reported based on event triggering, and another kind is periodically to report.
Further exemplarily, the 6H event updates control message that UE is received can be specifically carried in measurement by the network equipment
Control message is issued, and now, the measurement type information that the measurement control message includes is 6H events, is wrapped in measurement control message
The update mode for including includes modification or deletes.
Another specific example according to above-mentioned method for handover control embodiment and it is unrestricted, when timer is according to triggering
During prolonging the information corresponding time period and carrying out timing, if detecting SNPL values more than or equal to the first default SNPL thresholdings
Value, or receive that the network equipment issues again with configured information, UE can reset timer.It is therein heavy with configured information
Include physical channel again with configured information, transmission channel again with configured information or radio bearer again with configured information, network
Equipment can be issued again with configured information when indicating UE to carry out direct-cut operation to UE, UE cuts is changed to again with matching somebody with somebody in configured information
On physical channel, transmission channel and/or the radio bearer put.
Another specific example according to above-mentioned method for handover control embodiment and it is unrestricted, received under the network equipment in UE
Before the 6H affair control messages of hair, the 6H events triggering mark inside the UE can also be initialized as not reporting
(FALSE)Mark;And in response to initiating 6H event measurement report message to the network equipment, UE identifies more 6H events triggering
New is to report(TRUE)Mark;Can also be after 6H events triggering mark be updated to report TRUE to identify, in response to detection
The SNPL values for arriving SNPL threshold values default more than or equal to first, or in response to receiving that the network equipment issues again with indicating
Information, triggers the 6H events mark and is updated to FALSE marks by TRUE marks.
In one embodiment of the invention, UE can carry out HSUPA industry business request information is sent to the network equipment
The dump power of SNPL, UE is reported when business application(UE Power Headroom, hereinafter referred to as:UPH)With total E-DCH
Buffer status(Total E-DCH Buffer Status, hereinafter referred to as:TEBS)Information.In addition, UE can also be with default measurement
