Description
Technical field
The present invention relates to mobile communication technology field, and in particular to a kind of method for handover control, terminal, source base station and target
Base station.
Background technology
Application-specific congestion control (ACDC, Application specific Congestion in data communication
Control for Data Communication) it is a kind of access control mechanism, operator can allow or prevent user
The access request of application-specific during equipment (UE) Idle state.ACDC is only applicable to the UE of Idle state, is not suitable for connected state
UE, it is the load surcharge for mitigating access network or core net that it, which is acted on, and ACDC fundamental characteristics is as follows：
1.ACDC is applied to UMTS grounding wireless access network (UTRAN) and evolution UTRAN (E-
UTRAN)。
2. home network, which is UE, configures at least four ACDC classifications, the application that operator defines is corresponded to respectively.
3. opening the obligation that the ACDC classifications in UE are home networks, how to classify and do not defined by 3GPP.
What 4.UE had a set of mechanism to be verified as that it opens ACDC classifications is one by information source.
5. service network is accessing net side broadcast control information, including：The obstruction information of each ACDC classification, one it is unrestrained
Whether the UE of trip should be limited to ACDC controls.
6. the obstruction information of broadcast is different in each cell, using the corresponding relation with ACDC classifications by local in UE
Network configuration.
7. this based on broadcast stops the ACDC classifications configuration inside information and UE, UE may determine whether to allow specific
The transmission of the access request of application.
8. service network should indicate ACDC while other Access Controls are performed, when ACDC and access style are limited
(ACB, Access Class Barring) control indicates simultaneously when, ACDC should cover ACB.
9. when multiple core nets share same access network, access network should be able to be different core nets individually
Perform ACDC.In order to relax the congestion of a shared access network, for justice, the obstruction ratio to different operators is set
Should be identical.
UE operating system is each application assigned application program identification (ID), and UE is wide by receiving home network
Broadcast or write by the remote sim card of core net, obtain application program ID and the corresponding relation of ACDC classifications.It might have more
The individual corresponding ACDC classification of different application program ID.
Home network is that UE configures ACDC applicating categories：
1. the application (access priority highest) for being limited most light, is configured as highest ACDC classifications, as ACDC#
1；
2. the second high ACDC classifications, as ACDC#2 must be configured as than the application more than ACDC#1 by being limited；With such
Push away.
3. the application (access priority is minimum) for being limited at most, be either configured as minimum ACDC classifications or
ACDC classifications are not configured.
The application of ACDC classifications it is not configured on UE, it should which minimum ACDC classifications are considered by UE.When using ACDC,
Service network broadcast stops information, stops information and is sent successively from the up to minimum of ACDC classifications.Home network and service network
Network may use different sorting techniques.Service network decides whether ACDC being applied on the UE of roaming.
ACDC classifications number on UE may be different with the ACDC classification numbers of service Web broadcast.Such case can betide
When UE is roamed, the ACDC classifications number of service network broadcast is different from UE home network.Therefore, now using following strategy：
1. if the ACDC classifications number of service network broadcast is more than what UE itself was configured, UE uses are corresponding with ACDC to be stopped
Information, the obstruction information of minimum classification in cell broadcast service is used for unfiled other application.And ignore other and itself
The unmatched obstruction information of ACDC classifications.
2. if ACDC classifications number corresponding to the obstruction information of service network broadcast is less than UE itself configuration, UE is matching
ACDC classifications use corresponding to stop information, to other application use serving cell in minimum classification obstruction information.
Here, the ACDC classifications of a matching refer to, the ACDC classifications sequence of the obstruction information of service network broadcast and UE
The ACDC classifications sequence of itself configuration is identical.
During ACDC Access Controls in service network, the different classes of ACDC of service network ordering protocol stops ginseng
Number, comprising " stopping the time " " obstruction probability ", specifically,
Stop the time：If ACDC classifications corresponding to application program a are #1, the ACDC#1 of the broadcast obstruction time is 100ms,
Then application program a connection request by ACDC strategies Yi Dan stopped, within ensuing obstruction time 100ms, application program a
Connection request will be blocked always.
Stop probability：If ACDC classifications corresponding to application program b are #2, the ACDC#2 of broadcast obstruction probability is 0.6, should
When initiating connection request with program b, UE is the random number between its generation 0-1, if random number is less than or equal to 0.6, is allowed
Access, if more than 0.6, refusal access.
Traditional ACDC be Idle state UE initiate Stochastic accessing before, Non-Access Stratum (NAS) layer service request (SR,
Service Request) hand down and give wireless heterogeneous networks (RRC) layer, include ACDC classifications (category)；Rrc layer is from being
It is known that stopping parameter in message of uniting, rrc layer performs ACDC judgements.
But when UE is in connected state, due to having built up user plane bearer, UE can directly send out data in application layer,
NAS layers are no longer sent out SR and asked to rrc layer, therefore the new business initiated during connected state will not pass through ACDC.
Because traditional ACDC acts only on the UE of Idle state, the UE without acting on connected state, this can cause to hitchhike
Problem：Because ACDC can only do access judgement in idle condition, when there is an application to be allowed to access network, established with network
RRC connections；Before RRC connections disconnection, the application of other low priorities, can be with around ACDC all without ACDC judgements are done again
Judgement, is directly accessed network.Obviously, the ACDC of prior art is unfavorable for distinguishing management and control to different application programs, and being unfavorable for should
With the fairness of priority between program.
Switching flow of the prior art is following is a brief introduction of, for example, a kind of switching that 3GPP TS36.300 agreements provide
Flow is as shown in figure 1, comprise the following steps：
101) source base station controls to UE sending measurings, by RRC Connection Reconfigration message to UE
Measurement type configured；
102) UE is configured to base station reporting measurement reports according to measurement；
103) source base station makes decisions according to measurement report, adjudicates the UE and occurs to switch between base station, it is also possible to load point
The triggering switching of the reason for load；
104) to target BS Handover Request message occurs for source base station, and instruction target BS switches over standard
It is standby, the MME UE S1AP ID for Old eNB UE X2AP ID, the MME distribution that handoff request message is distributed containing source base station, need
The address of the data transmission of core-network side corresponding to the EPS to be established carrying lists and each EPS carryings.Target ENB is received
Start after Handover Request to switch into E-RABs carry out admission processing；
105) target BS carries out acceptance judging, the SAE bearing resources of the access distribution interface-free resources for being UE and business；
106) after the success of target base station resources access, Handover Request Acknowledge Handover Request are sent to source base station
ACK message, instruction switching preparation are completed, " Handover Request Acknowledge " the message package UE of eNB containing New X2AP ID, Old eNB
UE X2AP ID, newly-built EPS carrying are corresponding in the address of D sides up-downgoing data transmission, the special access signature of target side distribution
Etc. parameter；
107) source base station reconfigures (RRC Connection Reconfiguration) to terminal transmission RRC connections and disappeared
Breath, after terminal receives RRC Connection Reconfiguration message, the attachment removal from source base station, then by with
Machine access procedure is synchronous with target BS foundation.To save length, no longer described in detail for subsequent step.
From the point of view of the call access control (step 101~105) of the handover scheme of prior art, target BS is only according to source base station
The E-RAB QoS informations sent carry out call access control, do not consider the current application programs (APP) of UE.Such as text chat
See two kinds of applications of video with online, their own E-RAB QoS grades may be identical, but the consumption to Internet resources have it is bright
Aobvious difference.On the other hand, cell-of-origin may also be different from the ACDC obstruction parameter configurations of Target cell, for example cell-of-origin regards to certain
The obstruction parameter of sound interval sequence is completely by the way that and obstruction of the Target cell for some reason to the video program is higher, switching
When discounting for ACDC stop parameter, be unfavorable for the fairness of Target cell.

Levelling.
The embodiment of the present invention is performed ACDC judgements by target BS in handoff procedure.It refer to Fig. 2, the embodiment of the present invention
A kind of method for handover control provided, comprises the following steps when applied to source base station：
Step 201, source base station determines that the terminal is nearest when judging to need a terminal switching to a target BS
Once perform the first ACDC classifications of ACDC judgements.
Here, source base station can switch over judgement to terminal in the way of prior art, for example, according in terminal
The measurement report of report, judges whether terminal needs to switch, and when needing switching, determines the target base of the terminal switching
Stand.
Unlike the prior art, the embodiment of the present invention is when it is determined that terminal needs to be switched to target BS, further
The last the first ACDC classifications for performing ACDC judgements are obtained, specific acquisition pattern has following several：
1) the last the first ACDC classifications for performing ACDC and adjudicating of the terminal that source base station reports according to the terminal,
Obtain the first ACDC classifications.
Here, terminal can report the current ACDC classifications for performing ACDC judgements in every ACDC judgement of execution
To source base station；The ACDC classifications that source base station is received and the executions ACDC that reports of maintenance terminal the last time is adjudicated, so as to
When terminal needs switching, according to the information of local maintenance, the last the first ACDC for performing ACDC judgements of the terminal is obtained
Classification.
2) measurement report for carrying the first ACDC classifications that the terminal that source base station parsing receives reports, is obtained
To the first ACDC classifications.
Here, source base station can configure to terminal sending measuring in advance, and the measurement configuration is except including prior art
Related content, such as information of adjacent cells, in addition to for indicating that the terminal reports the last ACDC for performing ACDC judgements
The configuration information of classification.The measurement configuration that terminal issues according to source base station measures and reports the measurement report of related cell,
The measurement report also carries the last the first ACDC classifications for performing ACDC judgements of terminal simultaneously, and source base station is according to the measurement
Report can obtain the first ACDC classifications.
Step 202, source base station sends the handover request of the terminal to target BS, and the handover request carries described
The information of first ACDC classifications.
Here, source base station sends handover request (Handover Request) message to target BS, and within the message
Carry the information of the first ACDC classifications.
Step 203, source base station receives E-RAB service quality and the first ACDC class of the target BS according to the terminal
The handover request ack message that carry out do not return after acceptance judging.
Here, after target BS receives above-mentioned handover request, acceptance judging is performed, specifically, according to the terminal
E-RAB service quality carries out acceptance judging, obtains the first court verdict；And according to the ACDC strategies of target BS to described
First ACDC classifications carry out ACDC judgements, obtain the second court verdict；According to first court verdict and the second court verdict,
Admission judgment result is obtained, wherein, it is described to connect when the first court verdict and the second court verdict allow to access target BS
Court verdict of receiving is to allow to receive；Otherwise, the admission judgment result is not allow to receive.Target BS is sentenced according to the receiving
Certainly result, handover request ack message is returned to source base station, specifically, when admission judgment result is allows to receive, can returned
Return Handover Request Acknowledge (Handover Request ACK) message；When admission judgment result is does not allow to receive, can return
Return handover request refusal (Handover Request NACK) message or switching prepares failure (HANDOVER PREPARATION
FAILURE) message is to source base station, to refuse this switching.
Step 204, source base station processing according to corresponding to performing the handover request ack message.
Here, it is Handover Request Acknowledge (Handover Request ACK) message in the handover request ack message
When, source base station can perform follow-up hand-off process in the way of prior art, such as perform the step 107 shown in Fig. 1；
The handover request ack message is that handover request refuses (Handover Request NACK) message or switching prepares failure
When (HANDOVER PREPARATION FAILURE) message is to source base station, source base station can terminate this handoff procedure.
