Description
Technical field
The application is related to communication technical field, more particularly to a kind of terminal UE connection control method.The application
Also relate to a kind of radio network controller (RNC).
Background technology
Have benefited from the characteristics such as network rate height and availability of frequency spectrum height, 4G (forth generation mobile communication technology)
LTE (Long Term Evolution, Long Term Evolution) futures are expected to become each operation bearing data service
Major networks, but current LTE network only supports that data service, speech business are needed by CSFB
(Circuit Switched Fallback, circuit switching fall-back) mode falls back to GSM (Global System
For Mobile Communication, global system for mobile communications) network rear can carry out.
When current existing network 2G/3G/4G networks are interoperated, GSM network and LTE network do not have
Direct neighboring BS relationship, they are same 3G network configuring adjacent cell relations.So terminal is completed in 2G networks
3G nets can be moved to by intersystem cell reselection or intersystem handover mode as speech business release is latter
Network, then in 3G network again by redirection, intersystem handover mode between intersystem cell reselection, system
Move to LTE network.If 4G network loads are high or first stage of construction is unstable, in the terminal of 4G networks
Can also have and 3G network can be switched to by reorientation or cell reselection mode, then 4G is moved back to proper moment
LTE network.
For technology trends are predicted and cost consideration, at present each network equipment vendor by
Step reduces or stops Innovation Input to 3G network, operator also not in newly-increased 3G network construction, according to
The regulation of 25.331 agreements, starts just possess support TD/LTE interoperability functions from R8, therefore each master at present
The terminal protocol version that the RNC of stream 3G network equipment vendors is supported is generally up to R9 versions, but 3GPP
Agreement has supported R12 versions.With the popularization of LTE terminal, subsequently have a large amount of highest versions (R10,
R11, R12 etc.) support that the terminal of LTE network is used in existing network, if 3G network side does not support that highest version is assisted
View, can cause the terminal that CSFB falls back to GSM network move back to 4G LTE networks, also can accordingly
The terminal of gravity treatment when causing 4G network busies or weak covering/be reoriented to 3G network cannot be accessed；It is likely to meeting
Cause highest version terminal do between system to the RNC for supporting lowest version agreement/system in reorientation failure.With
As a example by RRC CONNECTION REQUEST message, increase newly in the message structure of R10 versions as follows
IE shown in table 1：
Table 1
The protocol version that terminal is supported accesses the RRC CONNECTION of RNC networks in terminal
REQUEST message and the transparent vessel of Target RNC is relocated to from different system or other RNC
Take in the SRNS RELOCATION INFO information elements included in ToTargetRNC_Container
Band.If ASN decodings after RNC only supports R9 versions, 3G network side RNC to receive this message may
Can fail or abandon message due to not supporting the high protocol version of terminal, cause high protocol version terminal without
Method is accessed.
Based on above-mentioned situation, if 3G network side will support that these highest version terminals are accessed and support high version
The New function of this terminal increase, new features, network side need updating protocol version or even need upgrading hardware
To support New function, new features, increase and branch processed to high protocol version, need to put into a large amount of manpowers,
Material resources cost is developed, tests and is disposed, and the New function of increased support highest version terminal, new
Characteristic does not have important Practical significance for the application of 3G network, is generally only the effect of making something perfect even more perfect, terminal
Supplementing for providing when the purpose that 3G network is accessed simply temporarily is resident 3G network or 4G Network Abnormals is used,
Therefore 3G network of being upgraded due to the upgrading of protocol version at any time, increased the operation cost and shadow of operator
Network stabilization is rung, cost performance is not high.
As can be seen here, if network side RNC needs to have support highest version terminal access capability, need
Increase the process branch accessed to highest version terminal.By taking the RNC of existing network main flow 3G equipment vendors as an example, RNC
It is generally maximum to support to arrive R9 versions, it is backward compatible to process branch comprising R4, R5, R6, R7, R8 version,
If more than R9 versions terminal to be received is accessed, to not only upgrade and support the ASN of highest version agreement, also need
Will according to protocol version and implementation procedure write respectively RRC access procedures, MM (Mobile Manage,
Mobile management) process and RBC processes (Radio Bearer control procedures, radio bearer control
Process processed) diversity of protocol versions process branch.And in addition to needing upgrading ASN versions, in addition it is also necessary to
Increase process branch, exploitation, test job amount respectively according to the protocol version of terminal and the process of execution
Greatly, the function that increases newly and in protocol version, field information, RNC or Node B may not support, i.e.,
Support is made, these fields or function realize meaning without too important for RNC, because terminal is generally only
It is temporary transient resident 3G network, or carries out conventional business to set up process, upgrading exploitation is exclusively carried out for this and is thrown
Enter output ratio too low, and because exploitation amount increases the possible defect that introduces and causes product unstable.

Specific embodiment
Existing network RNC (Radio Network Controller, radio network controller) is for the new end accessed
End, generally presses and accesses the terminal versions Resources allocation of message instruction, organizes correspondence version message to issue end
End, such as terminal are accessed with REL-n (n=3,4,5,6,7,8,9 ...) version, then RNC organizes corresponding REL-n
The message of version issues terminal, terminal versions RRC request messages and RNC reorientations enter it is transparent
Carry in container (ToTargetRNC_Container), so that RRC is accessed and reorientation enters as an example, in RRC
In access procedure, terminal sends RRC CONNECTION REQUEST message, RNC to UTRAN
ASN is carried out to message and solves the IE (Information element, message element) that message package contains,
IE indicates the ability that terminal sends RRC the reason for ask, terminal protocol version and terminal, RNC
These information are preserved, then according to the corresponding local resource of version and ability distribution of terminal, wireless money
Source, then according to terminal versions information tissue and version information identical RRC CONNECTION
SETUP message issues terminal.
It is similar with RRC accesses, current RNC, current RNC are relocated to from different system or other RNC
It is also required to reference to the terminal capability, version information carried in transparent vessel (ToTargetRNC_Container),
RNC is the suitable local resource of terminal distribution, Radio Resource, then according to version information, tissue correspondence
The Inter-System Handover Command of the RBC message (Radio Bearer Control) or correspondence version of version
(HandoverToUTRANCommand) different system or source RNC are issued, instruction terminal is according to message arrangement
The cell being switched under current RNC.By taking reorientation between RNC as an example, terminal versions are included in
It is sent to by transparent vessel (ToTargetRNC_Container) in ue-RadioAccessCapability IE
Current RNC.
Based on above-mentioned situation, if the highest version of current RNC is accessed less than RRC or reorientation enters to disappear
The version indicated in breath, and RNC sides do not upgrade and ASN versions and increase high protocol version and process point
, then current RNC cannot ask the transparent vessel code stream that code stream or reorientation enter to enter the RRC for receiving
Row ASN decode, cause RRC access failures or reorientation to enter failure, can not only affect user perceive and
KPI, also influences whether that LTE terminal moves back to LTE network and LTE network business from other subsystems
Shunting.
In view of the problem in background technology, present applicant proposes a kind of terminal UE connection control method, right
Highest version protocol terminal carries out RRC accesses in current RNC, and RNC indicates that drop version can be propped up to RNC
The highest protocol version held is appointed as certain particular version, it is possible to receives and supports most higher than RNC
The terminal of highest version is accessed, and makes which move back to LTE network in proper moment, or for highest version
RRC access requests send RRC refuse informations and carry redirection information (LTE/GSM of current area is adjacent
Area's information), indicate which is redirected to other networks, being accessed using drop version can be in RNC or redirect
It is upper to be determined by configuration parameter.Enter in current RNC reorientations accordingly for highest version protocol terminal,
Highest protocol version or be appointed as certain particular version that RNC instruction drop versions can be supported to RNC, press
Highest protocol version or certain particular version tissue switching command instruction terminal carry out RNC reorientations and enter, and
Make which LTE network be moved back in proper moment, or for the RNC reorientations of highest version enter request, return
Relocation process failed message, forbids entering in current RNC reorientations, it is allowed to drops version reorientation and accesses also
It is to reply unsuccessfully refusal reorientation to enter and can determine by configuration parameter on RNC.
As shown in figure 1, a kind of schematic flow sheet of the UE connection control methods proposed for the application, including
Following steps：
S101, RNC determine the terminal protocol version of the UE according to the access request that terminal UE sends.
Can accurately to obtain the situation of UE, in the application preferred embodiment, RNC is receiving institute
After stating the RRC access request message of UE transmissions, ASN solutions will be carried out to RRC access requests message
Code, the triggering reason carried in obtaining and preserving the RRC access requests message, terminal association
The LTE abilities of view version and the UE.
The application to comprising protocol version access message (rrc request, 3/4G interoperability reorientation enter or
Reorientation between RNC enters message) structure upgraded, works as when terminal is accessed or is reoriented in current RNC
During front RNC, if terminal protocol version is higher than the highest protocol version that current RNC is supported, RNC pair
Terminal protocol version is processed by the treatable highest protocol versions of current RNC, i.e., terminal drop version is processed.
Only modification ASN files, increase the corresponding RRC CONNECTION REQUEST of highest version agreement and disappear
The process of the SRNS RELOCATION INFO that breath and reorientation enter, to ensure network side ASN
Decoder can be correctly decoded and be processed for the message that highest version terminal sends, than if being correctly decoded
Go out the RRC CONNECTION REQUEST message and the IE for including of the transmission of highest version terminal.
Whether S102, the RNC judge the terminal protocol version higher than the highest agreement itself supported
Version.
After terminal protocol version is obtained by S101, technical scheme is subsequently by the height to accessing
Version terminal carries out access process, such as RNC highests according to the highest protocol version that RNC can be supported
REL-9 versions are supported, the terminal of access is REL-11 versions, then RNC disappearing according to REL-9 versions
Breath format organization RRC CONNECTION SETUP message is sent to terminal, waits terminal replies RRC
After CONNECTION SETUP COMPLETE message, RRC access procedures are completed.
S103, if so, LTE abilities of the RNC according to the UE, the triggering of the access request
The adjacent area of the cell that reason, blind redirection of switches and UE request is accessed, indicates that the UE is carried out
Redirect or according to the highest protocol version process access request.
In for highest version terminal RRC access procedure, if triggering RRC is PS business the reason for request
Related causes or registration, intersystem cell reselection reason, and terminal support LTE abilities, and currently
Cell is furnished with LTE adjacent areas, and RNC can send RRC refuse informations after RRC access request message is received
Carrying LTE redirection informations instruction terminal carries out blind redirection, and this function is by RNC on-off control.If
Being unsatisfactory for possessing LTE abilities or current area does not have LTE adjacent areas or is unsatisfactory in RRC reason for claim
Any one, then the normal access process of RRC of the highest version that can be supported by RNC is processed.
Therefore, in the application preferred embodiment, the step is processed based on situations below：
(1) if the UE possess the LTE abilities, the cell have LTE adjacent areas, it is described touch
Send out reason to meet specified requirementss and the blind redirection of switches is currently opening, and the RNC is to institute
State UE transmissions to redirect；
(2) if the UE do not possess the LTE abilities or the cell do not have LTE adjacent areas,
Or the triggering reason not meet specified requirementss or the blind redirection of switches be not currently opening,
The RNC is according to the highest protocol version process access request.
It should be noted that for the reorientation in S103 enters process, the application is performed according to same procedure,
In subsequent process after RRC is accessed or reorientation enters, if terminal possesses LTE abilities, RNC can be with
Whether LTE neighboring BS information is configured according to current service cell, decides whether weight between instruction terminal trial system
Between orientation, system, relocation loading mode moves back to LTE network.For the RNC reorientations of highest version terminal enter,
The highest protocol version supported by RNC processes reorientation and enters flow process.After reorientation success, if terminal tool
Standby LTE abilities and current service cell is configured with LTE adjacent areas, can send 3A measurement control messages,
If terminal to report carries the 3A measurement reports of LTE information, RNC judgements are with reorientation still weighing
Oriented approach moves to LTE network.If adopting relocation loading mode, RNC is constructed and the actual versions of UE
The transparent vessel structure for matching issues eNB, processes reorientation by the true versions of UE and goes out flow process；If
Using the mode of redirection, the highest version supported by RNC is sent out from RRC release messages carrying LTE and is reset
To information.
In the preferred embodiment of the application, when the redirection that the RNC receives the UE transmissions please
When seeking message, the RNC is decoded to the transparent vessel carried in the Redirection Request message, with
Obtain the terminal protocol version of the UE afterwards according to the transparent vessel, and judge the terminal protocol
Whether version is higher than the highest protocol version itself supported.Different court verdicts and handling process are such as
Under：
(1) if the terminal protocol version is higher than the highest protocol version, according to the highest agreement
The UE is accessed by version, and carries out weight after the LTE abilities of the UE that is disposed to the UE
Position into process.
In this case, RNC first determines whether whether the UE has the LTE abilities, if it is determined that
As a result it is yes, then RNC preserves the ability information of LTE abilities, and to the UE after preservation is finished
Carry out reorientation to enter to process；If it is judged that being no, RNC carries out reorientation and enters to process to the UE.
(2) if the terminal protocol version is not higher than the highest protocol version, weight is carried out to the UE
Position into process.
It should be noted that the highest version terminal that reorientation enters, if supporting LTE abilities and currently taking
Business cell has LTE adjacent areas, sends 3A measurements control message and LTE adjacent areas are measured, if terminal
The measurement report of LTE adjacent areas, RNC has been reported to be judged using redirection or reorientation according to type of service,
Principle is if CS business adopts relocation loading mode, if PS business is redirected or relocation loading mode
Can adopt.After so accessing for highest version terminal drop version, if if receiving carrying receives carrying
The 3A measurement report messages of LTE information, it is if necessary to initiate reorientation, saturating by the actual version tissue of terminal
Message in bright container, it is only necessary to increase highest version reorientation and go out to process branch, without adding other high versions
This protocol processes branch.
In order to the technological thought of the application is expanded on further, in conjunction with specific application scenarios, to the application
Technical scheme illustrate.
As shown in Fig. 2 the handling process schematic diagram that the RRC proposed for the application specific embodiment is accessed,
Comprise the following steps：

The highest protocol version that RNC is supported, is processed by normal RRC accesses if not higher than, by version information
Preserve to UE contexts (UE Contex), RNC sides send and access the RRC that version matches
CONNECTION SETUP message.
Highest protocol versions of the step b) if above RNC, then the highest protocol version supported by RNC
Process, version information is preserved to UE contexts (UE Contex), if LTE is carried in RRC requests
Ability, then preserve LTE ability informations, subsequently decide whether to need to refer to this when can move back to LTE network
A little abilities, initiate to redirect if blind redirection condition is met, otherwise process by normal RRC accesses.
The process of follow-up other signaling procedures of step c) is with preservation in UE contexts (UE Contex)
Protocol version process.
As shown in figure 3, between the system proposed for the application specific embodiment/system in the process that enters of reorientation
Schematic flow sheet, comprises the following steps：
The current RNC of step a) receive relocation request message, to the transparent appearance carried in message
Device (ToTargetRNC_Container) is decoded.
The version that step b) is carried in getting transparent vessel, the agreement version supported with current RNC highests
Originally compare, if the highest version supported less than RNC, access by the version that transparent vessel is carried,
Version information is saved into into UE contexts (UE Contex).
It is if version is carried in step c) transparent vessels higher than the protocol version that RNC highests are supported, right
Terminal carries out dropping version access, the highest protocol version Resources allocation supported according to RNC, tissue switching life
Version information is saved into UE contexts (UE Contex) by order, while preserving the true version of UE.
Step d) reorientation is entered successfully after other processes, if reorientation goes out and UE is true
Effectively, then RNC constructions and the true version identical transparent vessel structures of UE are sent to target to real version
RNC/eNB processes reorientation and goes out flow process, otherwise processes by the version in UE contexts.
