Description
Technical field
The present invention relates to fields of communication technology, more particularly to the sending method and system of a kind of Radio Bearer message.
Background technique
If the source cell of user equipment (User Equipment, UE) and Target cell belong to different wireless network controls
Device (Radio Network Controller, RNC) processed, then UE is known as resetting from the process that source cell is switched to Target cell
Position, the process of reorientation are as follows:
Step 1:UE uploads measurement report to source RNC, and source RNC selects the cell for being switched to Target RNC according to measurement report.
It is fixed that RNC transmission reorientation demand (Relocation Required) message in source starts afterwards to core net (Core Network, CN)
When device TrelocPrep, Relocation Required message in include source RNC distribution resource information, CN forward message weight
Location Request (Relocation Request) message is to Target RNC.
Step 2: after Target RNC receives Relocation Request message, resource is distributed in Target RNC, it is small in target
Area establishes Radio Link and IU (interface between CN and RNC) and IUB (interface between RNC and base station (NODE B)) transmission is held
It carries.The resource information composition radio bearer of distribution is reconfigured (Radio Bearer Reconfiguration) and disappeared by Target RNC
Breath, which is included in, to be issued CN in re-positioning request confirmation (Relocation Request Acknowledge) message and starts timing
Device TrelocFinish.CN forwarding message resets order of the bit (Relocation Command) message to source RNC.
Step 3: source RNC stops timer TrelocPrep after receiving Relocation Command message, will wherein wrap
The Radio Bearer Reconfiguration message contained issues UE, while starting timer TrelocOverall.UE is received
After Radio Bearer Reconfiguration message, sends radio bearer and reconfigure completion (Radio Bearer
Reconfiguration Complete) message is to Target RNC.
Step 4: Target RNC stops timing after receiving Radio Bearer Reconfiguration Complete message
Device TrelocFinish sends to redirect to CN and completes (Relocation Complete) message.CN is sent out after receiving to source RNC
IU release command (Iu-Release Command) message instruction release source UE corresponding resource is sent, source RNC receives Iu-
Stop timer TrelocOverall after Release Command message, reorientation process is completed.
In the step 3 and 4 in repositioning process, wireless environment it is poor, there are interference or flower arrangement configuration when, greatly
Probability, the source cell downlink step-out after UE transmission measurement report with source RNC can not receive radio bearer reconfiguration message, or
UE is received with Target RNC Target cell downlink step-out after radio bearer reconfiguration message, and Target RNC can not receive radio bearer reconfiguration
It sets and completes message, alternatively, handover delay becomes larger although hand off signaling is normal, packet switch (Packet occur
Switching, PS) rate falls zero, circuit switching (Circuit Switching, CS) quality for a long time and is deteriorated even call drop etc.
The case where index error.
It is retouched according to third generation partner program (3rd Generation Partnership Project, 3GPP) agreement
State, after UE detects down wireless link step-out, UE discharge dedicated physical channel resource, close uplink and downlink data, physical layer into
Row cell is searched again, and after searching out new cell, it is Radio Link Failure (Radio Link that reason is sent from new cell
Failure cell update (Cell Update) message).If cell update success, saves and keeps UE online, otherwise UE
Call drop occurs.
According to 3GPP agreement, network sends nothing to UE using AM affirmation mode in signal transmission radio bearer 2 (SRB2)
Line carries command messages, wherein carrying radio bearer and activationary time (Activative Time) parameter, instruction UE is in activation
Between put after new system configuration information will come into force, activationary time be complete Connection Frame Number (Connection Frame Number,
CFN relative value), range are (0,255).Repositioning process uses hard handover, and network side is in Radio Bearer
Mono- activationary time parameter of UE is told in Reconfiguration idle message, is arrived the moment in activationary time, RNC and UE are same
Step is switched to new configuration.In order to guarantee RNC and UE on activationary time point synchronism switching to new configuration, it is necessary to assure in activation
Between point arrive before, UE is completely received the radio bearer command messages from RNC.RNC is (logical by Uu to the configuration information of UE
With the air interface of mobile communication system (Universal Mobile Telecommunications System, UMTS))
Radio Bearer Reconfiguration message is realized.If activationary time setting is too small will to will lead to RNC and UE cannot
Synchronism switching further results in the problem of communication signalings such as downlink step-out interrupt to new configuration.
Now net in order to solve UE cannot normally receive network side transmission radio bearer command messages caused by activate when
Between the problem of failing, increase activationary time usually to elongate propagation delay time, but the average call time delay that will lead to network is drawn
Greatly, the networks survivabilities index of operator is influenced.

Step 100, according to the propagation delay time of Radio Bearer message transmission and repetition period, and, current target is small
The System Frame Number in area determines activationary time parameter.
Activationary time parameter determines that the signaling Key Performance of the wireless communication procedures such as reorientation examines (Key
Performance Indicator, KPI) index and call delay.
The formula for calculating activationary time parameter is as follows:
Activative Time=((((SFN+To Ue Transfer Delay) %256)/RP+1) * RP), in which:

Step 102, the Radio Bearer message for carrying the activationary time parameter is sent to user equipment.
Now the repetition period referring to 80 milliseconds of integral multiple value, is fixed as 8, does not consider that the TTI of UE practical business matches in net
Set value.Now the TTI possible configuration value in the uplink and downlink direction of SRB, CS business in net, PS business is 10 milliseconds, 20 milliseconds, 40
Millisecond, 80 milliseconds etc., most TTI are less than 80 milliseconds.If the TTI in the uplink and downlink direction of SRB, CS business of UE, PS business is not
Comprising 80 milliseconds, the value for sending the repetition period of idle message takes 8, will lead to idle message and is delayed by transmission.
The embodiment of the present invention is in view of the idle message of UE in repositioning process, the signaling, the CS industry that need to distribute on network
Business, PS business (may be multiple) resource information are allocated to UE, for continuous dispensing and frame point distribution, in order to which UE smoothly finds TTI
Boundary, repetition period are between the current Transmission Time Interval of whole signalings of the user equipment and the transmission time of business configuration

Line bearer messages are sent to user equipment；Wherein, the repetition period is the Transmission Time Interval of the current whole signalings of user equipment
With the least common multiple of the Transmission Time Interval of business configuration.By the way that the value of repetition period is arranged, activation is accurately calculated
Time parameter guarantees that radio bearer command messages are completely sent to user equipment before activationary time point, reduces network
Average call time delay, improve the networks survivabilities index of operator.
Embodiment two

Referring to Fig. 2, a kind of step flow chart of the sending method of Radio Bearer message in the embodiment of the present invention is shown.
Step 200, propagation delay time is determined according to the type of service that propagation delay time is applicable in.
Propagation delay time should configure different numerical value under different scenes, need to refine specific type of service, the industry
Service type may include H composite service, R4 composite service, H service switching and frame point etc..It is passed under various scenes in cell parameter table
The concrete configuration of defeated time delay is as shown in table 1
Table 1
Step 202, according to the propagation delay time of Radio Bearer message transmission and repetition period, and, current target is small
The System Frame Number in area determines activationary time parameter.
Activationary time parameter determines that the signaling Key Performance of the wireless communication procedures such as reorientation examines (Key
Performance Indicator, KPI) index and call delay.
The formula for calculating activationary time parameter is as follows:
Activative Time=((((SFN+To Ue Transfer Delay) %256)/RP+1) * RP), in which:
SFN is the System Frame Number of current time point target cell.
To Ue Transfer Delay indicates propagation delay time, it is abstract syntax notation one (Abstract to be transmitted
Syntax Notation One, ASN1) coded message length is divided by signaling transmission time interval (Transmission Time
Interval, TTI) in the transmission duration that obtains after the message-length that can send, i.e. the idle message of ASN1 coding can be more
A few signaling TTI is sent completely, which is rule of thumb to estimate with the average delay statistical value of network, can be according to reality
Situation static configuration or dynamic adjust.
RP, that is, repetition period indicates times of the minimum interval relative to signaling TTI (taking 10ms) for sending idle message
Number, the smaller chance for representing transmittable information of RP is more, and propagation delay time is smaller, and acquisition system data throughput is higher, realization
Rate is also bigger.
Preferably, the activationary time parameter includes outer layer activationary time and internal layer activationary time.
Preferably, the step 202 can be with are as follows:
In the repositioning process of radio network controller, when the uplink and downlink of the Target cell are continuous dispensing
When, the outer layer activationary time for indicating to activate immediately will be carried and indicates the Radio Bearer message of the internal layer activationary time activated immediately
It is sent to user equipment, and the outer layer activationary time for indicating non-immediate activation will be carried after secondary reorientation and indicated non-immediate
The Radio Bearer message of the internal layer activationary time of activation is sent to user equipment.
When the uplink of the Target cell and/or lower behavior frame point distribution, the outer layer for indicating non-immediate activation will be carried
Activationary time and the internal layer activationary time Radio Bearer message of the non-immediate activation of expression are sent to user equipment, wherein the table
Show that non-immediate to swash movable internal layer activationary time be the outer layer activationary time and dedicated physical channel for indicating non-immediate activation
The sum of offset.
Specifically, area is needed when filling in the activationary time in Uu mouthfuls of radio bearer reconfiguration messages for repositioning process
Partial objectives for cell whether continuous dispensing.
It is described according to 3GPP agreement, there are 3 activationary time fields in idle message, an activationary time for message,
Other two is dedicated physical channel (Dedicated Physical Channel, DPCH) activationary time.Wherein, two DPCH
Activationary time is respectively uplink and downlink DPCH activationary time.
The description of activationary time is as shown in table 2 in 10.3.3.1 chapters and sections in 3GPP agreement:
Table 2
Activation Time defines operation caused by related news or changes the frame number/time point come into force in table 2,
What is indicated is the absolute value of CFN, and value is between 0 to 255.
The description of Time info is as shown in table 3 in 10.3.6.83 chapters and sections in 3GPP agreement:
Table 3
Activation time in table 3 is DPCH activationary time, is present in Time info field, the Time
Info field is respectively present in uplink DPCH information and downlink DPCH information.Activation in uplink DPCH information
Time is uplink DPCH activationary time, and the activationary time in downlink DPCH information is downlink DPCH activationary time.Generally,
For the user of frame point distribution, ectonexine activationary time relationship is as follows: internal layer activationary time=outer layer activationary time+DPCH is inclined
It moves.Wherein, DPCH offset indicates that frame divides the start offset value of user's upload or downloading data, and repetition period and repeat length determine
DPCH offset is immutable afterwards.For other Uu mouthfuls of message, as radio bearer establish (Radio Bearer Setup) message and
Radio bearer discharges (Radio Bearer Release) message also similar carrying DPCH activationary time.
When uplink and downlink all continuous dispensings of Target cell, outer layer and internal layer activationary time are all to activate immediately.And
It is secondary to reset and after being that the Cell Update message of Radio Link Failure is sent to source RNC when the reason of relocate unsuccessfully for the first time
Outer layer and internal layer fill in activationary time behind position, prevent from repeatedly sending Cell Update message.
When at least one direction of the upstream or downstream of Target cell is frame point distribution, the outer layer of activationary time fills in activation
Time, internal layer activationary time=outer layer activationary time+DPCH offset.
Step 204, simplify the addition in the Radio Bearer message for carrying the activationary time parameter or reconfigure
Descending transmission channel information.
Preferably, the step 204 can be with are as follows:
When the type of the type of uplink transport channel, mark and TFS Transport Format Set information and descending transmission channel, mark and
When TFS Transport Format Set information is all identical, in the addition or reconfigures in descending transmission channel information and delete descending transmission channel
TFS Transport Format Set information.
Uplink transport channel message (Added or is added or reconfigured in 3GPP agreement in 10.3.5.2 chapters and sections
Reconfigured UL TrCH information) it describes as shown in table 4:
Table 4
Descending transmission channel message (Added or is added or reconfigured in 3GPP agreement in 10.3.5.1 chapters and sections
Reconfigured DL TrCH information) it describes as shown in table 5:
Table 5
According to table 4 and table 5, transmission channel (Added or Reconfigured TrCH) packet is added or reconfigured
Type, mark and TFS Transport Format Set (Transport Format Set, TFS) information of the transmission channel containing uplink and downlink.When it is upper,
When the transmitting channel information of downlink is identical, descending transmission channel type, mark and the TFS information of redundancy are sent to UE, lead to sky
Mouth message code stream is larger, increases air interface transmission time delay.
Described according to table 5 it is found that when the type of uplink and downlink transmission channel, mark and all identical TFS information, increase or
The descending transmission channel information reconfigured uses " SameAsUL " option, only fills in type, the mark of uplink transport channel, omits
Descending transmission channel TFS information.It is established for SRB and CS, PS or reconfiguration setting optimization switchs, idle message is carried out at weight reducing
Reason.For repositioning process, message weight reducing is carried out to the transmission channel of SRB, CS and PS, idle message size can be made to reduce
26Byte can reduce the transmission duration of 2 signaling TTI.
Step 206, the Radio Bearer message for carrying the activationary time parameter is sent to user equipment.
Now the repetition period referring to 80 milliseconds of integral multiple value, is fixed as 8, does not consider that the TTI of UE practical business matches in net
Set value.Now the TTI possible configuration value in the uplink and downlink direction of SRB, CS business in net, PS business is 10 milliseconds, 20 milliseconds, 40
Millisecond, 80 milliseconds etc., most TTI are less than 80 milliseconds.If the TTI in the uplink and downlink direction of SRB, CS business of UE, PS business is not
Comprising 80 milliseconds, the value for sending the repetition period of idle message takes 8, will lead to idle message and is delayed by transmission.
The embodiment of the present invention is in view of the idle message of UE in repositioning process, the signaling, the CS industry that need to distribute on network
Business, PS business (may be multiple) resource information are allocated to UE, for continuous dispensing and frame point distribution, in order to which UE smoothly finds TTI
Boundary, repetition period are between the current Transmission Time Interval of whole signalings of the user equipment and the transmission time of business configuration
Every least common multiple, increase idle message send chance, reduce propagation delay time.
In conclusion the technical solution in the embodiment of the present invention, according to the propagation delay time of Radio Bearer message transmission and again
The multiple period, and, the System Frame Number of current target cell determines activationary time parameter；The nothing of activationary time parameter will be carried
Line bearer messages are sent to user equipment；Wherein, the repetition period is the Transmission Time Interval of the current whole signalings of user equipment
With the least common multiple of the Transmission Time Interval of business configuration.By the way that the value of repetition period is arranged, activation is accurately calculated
Time parameter guarantees that radio bearer command messages are completely sent to user equipment before activationary time point, reduces network
Average call time delay, improve the networks survivabilities index of operator.
The value that propagation delay time is obtained according to different scene dynamics improves the accuracy of activationary time calculating.
When filling in the activationary time for relocating Radio Bearer message of eating dishes without rice or wine, distinguishing Target cell is continuous dispensing or frame point
Distribution.When the uplink and downlink of Target cell are continuous dispensings, activationary time is to activate immediately, when reorientation failure for the first time
The reason is that outer layer and internal layer are filled in sharp after secondary reorientation after the Cell Update message of Radio Link Failure is sent to source RNC
Live time.When at least one direction is frame point distribution in the uplink and downlink of Target cell, when the outer layer of activationary time fills in activation
Between, internal layer activationary time=outer layer activationary time+DPCH offset prevents from repeatedly sending Cell Update message
When the type of uplink and downlink transmission channel, mark are identical with TFS information, omitted using " SameAsUL " option
The downlink TFS information of redundancy in idle message reduces transmission duration.
