Description
Technical field
This application involves field of communication technology, in particular to a kind of terminal UE connection control method.The application also relates to simultaneously
And a kind of radio network controller (RNC).
Background technique
Have benefited from the characteristics such as network rate height and availability of frequency spectrum height, 4G (fourth generation mobile communication technology) LTE (Long
Term Evolution, long term evolution) following major networks for being expected to that each operation bearing data service can be become, but current
LTE network only supports data service, voice service to need through CSFB (Circuit Switched Fallback, circuit switching
Falling after rise) mode falls back to GSM (Global System for Mobile Communication, global system for mobile communications) net
Network rear is able to carry out.
When current existing net 2G/3G/4G network is interoperated, there is no direct adjacent areas for GSM network and LTE network
Relationship, they are same 3G network configuring adjacent cell relationships.Terminal can generally lead to after 2G network completes voice service release in this way
It crosses intersystem cell reselection or intersystem handover mode moves to 3G network, then pass through intersystem cell weight again in 3G network
It is redirected between choosing, system, intersystem handover mode moves to LTE network.If 4G network load is high or first stage of construction is unstable
Fixed, can also have in the terminal of 4G network can be switched to 3G network by reorientation or cell reselection mode, then move to proper moment
Return 4G LTE network.
For to technology trends prediction and the considerations of cost, current each network equipment vendor gradually reduced or
Stop the Innovation Input to 3G network, operator does not also build in newly-increased 3G network, according to the regulation of 25.331 agreements, opens from R8
Beginning, which just has, supports TD/LTE interoperability function, therefore the terminal protocol that the RNC of each mainstream 3G network device manufacturer is supported at present
Version is generally up to R9 version, but 3GPP agreement has supported R12 version.It is subsequent to have greatly with popularizing for LTE terminal
Amount highest version (R10, R11, R12 etc.) supports the terminal of LTE network to use in existing net, if 3G network side does not support highest version to assist
View, will lead to CSFB and fall back to the terminal of GSM network can not move back to 4G LTE network, also result in accordingly 4G network busy or
The terminal of gravity treatment when weak covering/be reoriented to 3G network can not access；Highest version terminal may also be will lead to support lowest version
The RNC of agreement does between system/system in reorientation failure.By taking RRC CONNECTION REQUEST message as an example, R10 version
Increase IE as shown in table 1 below in message structure newly:
Table 1
The protocol version that terminal is supported is in the RRC CONNECTION REQUEST message of terminal access RNC network and from different
System or other RNC are relocated to the SRNS in the transparent vessel ToTargetRNC_Container of Target RNC included
It is carried in RELOCATION INFO information element.After if RNC only supports R9 version, 3G network side RNC equipment to receive this message
ASN decoding may will fail or abandon message due to not supporting the high protocol version of terminal, cause high protocol version terminal without
Method access.
Based on the above situation, if 3G network side will support these highest version terminals to access and highest version terminal is supported to increase
The new function that adds, new features, network side need updating protocol version even to need upgrading hardware to support new function, new features,
Increase and branch is handled to high protocol version, need to put into a large amount of human and material resources costs and developed, tested and disposed, and increases
The new function of the support highest version terminal added, new features, using unimportant Practical significance, are generally only for 3G network
The effect of making something perfect even more perfect, the supplement that terminal is provided when the purpose of 3G network access is temporarily to be resident 3G network or 4G Network Abnormal
It uses, therefore upgrades 3G network at any time due to the upgrading of protocol version, increase the operation cost of operator and influence network
Stability, cost performance be not high.
It can be seen that needing to increase to high version if network side RNC, which needs to have, supports highest version terminal access capability
The processing branch of this terminal access.By taking existing host flows the RNC of 3G device manufacturer as an example, RNC is usually maximum to be supported to arrive R9 version, to
Lower compatibility includes that R4, R5, R6, R7, R8 version handle branch, if R9 or more version terminal to be received to access, not only to be upgraded
Support the ASN of highest version agreement, it is also necessary to write RRC access procedure, MM respectively according to protocol version and implementation procedure
(Mobile Manage, mobile management) process and RBC process (Radio Bearer control procedures, wirelessly
Carry control process) diversity of protocol versions handle branch.And other than needing to upgrade ASN version, it is also necessary to according to terminal
Protocol version and execution process increase separately processing branch, exploitation, test job amount it is big, and in protocol version increase newly
Function, field information, RNC or Node B may not support, even if supporting, these fields or function are for RNC too heavy
The realization meaning wanted, because terminal is generally only temporarily to be resident 3G network, or carry out common business establishment process, thus specially
It is too low to carry out upgrading exploitation input-output ratio, and because exploitation amount increases and may introduce defect and cause product unstable.

Specific embodiment
Now net RNC (Radio Network Controller, radio network controller) is for the terminal that newly accesses, usually
It presses the terminal versions number distribution resource of access message instruction, corresponding version message is organized to issue terminal, such as terminal with REL-n (n
=3,4,5,6,7,8,9 ...) version accesses, then RNC organizes the message of corresponding REL-n version to issue terminal, and terminal versions exist
RRC request message and RNC relocate into transparent vessel (ToTargetRNC_Container) in carry, with RRC access and
For relocating, in RRC access procedure, terminal to UTRAN send RRC CONNECTION REQUEST message, RNC pairs
Message carries out ASN and solves the IE (Information element, message element) that message includes, and IE indicates terminal hair
The ability of the reason of sending RRC to request, terminal protocol version and terminal, RNC save these information, then according to the version of terminal
And the corresponding local resource of capability distribution, radio resource, it is then identical with version information according to terminal versions information tissue
RRC CONNECTION SETUP message issues terminal.
It is similar with RRC access, it is relocated to current RNC from different system or other RNC, current RNC is also required to reference to transparent
Terminal capability, the version information carried in container (ToTargetRNC_Container), RNC are that terminal distribution is suitably local
Resource, radio resource, then according to version information, organize corresponding version RBC message (Radio Bearer Control) or
The Inter-System Handover Command (HandoverToUTRANCommand) of corresponding version issues different system or source RNC, instruction terminal are pressed
The cell under current RNC is switched to according to message arrangement.For relocating between RNC, terminal versions are included in ue-
Current RNC is sent to by transparent vessel (ToTargetRNC_Container) in RadioAccessCapability IE.
Based on the above situation, if the highest version of current RNC accesses or relocate the version indicated in message lower than RRC
This, and the side RNC does not upgrade ASN version and increases high protocol version processing branch, then and current RNC can not be to the RRC received
Request code stream or relocate into transparent vessel code stream carry out ASN decoding, lead to RRC access failure or relocate into failure, no
But it will affect user's perception and KPI, also influence whether that LTE terminal is moved back to from other subsystems to LTE network and LTE network industry
Business shunts.
In view of the problems in background technique, present applicant proposes a kind of terminal UE connection control methods, assist to highest version
It discusses terminal and carries out RRC access in current RNC, RNC instruction drop version to the supported highest protocol version of RNC or is appointed as certain
A particular version, so that it may receive the terminal access for being higher than the highest version that RNC is supported, and move back to it in proper moment
LTE network, or for highest version RRC access request send RRC refuse information and carry redirection information (current area
LTE/GSM neighboring BS information), it indicates that it is redirected to other networks, using the access of drop version or redirects and can lead on RNC
Cross configuration parameter decision.It is relocated in current RNC into RNC instruction drop version to RNC accordingly for highest version protocol terminal
The highest protocol version that can support is appointed as some particular version, cuts by highest protocol version or some particular version tissue
It changes order instruction terminal and carries out RNC and relocate into and it being made to move back to LTE network, or the RNC for highest version in proper moment
It relocates into request, returns to relocation process failed message, forbid relocating in current RNC into allowing to drop version reorientation and connect
Enter or reply unsuccessfully refusal to relocate and can determine on RNC by configuration parameter.
As shown in Figure 1, a kind of flow diagram of the UE access control method proposed for the application, comprising the following steps:
S101, RNC determine the terminal protocol version of the UE according to the access request that terminal UE is sent.
The case where can accurately to obtain UE, in the application preferred embodiment, RNC is receiving what the UE was sent
After RRC access request message, ASN decoding will be carried out to RRC access request message, and obtain and save the RRC access request
The LTE ability of the triggering reason, the terminal protocol version and the UE that are carried in message.
The application (weighs the access message comprising protocol version rrc is requested, the reorientation of 3/4G interoperability enters or RNC
Positioning into message) structure upgraded, when terminal is when current RNC is accessed or is reoriented to current RNC, if terminal protocol version
This is higher than the highest protocol version that current RNC is supported, the highest agreement version that RNC can be handled terminal protocol version by current RNC
Present treatment, i.e., to terminal drop version processing.Only modification ASN file increases the corresponding RRC CONNECTION of highest version agreement
REQUEST message and relocate into SRNS RELOCATION INFO message processing, to guarantee network side ASN decoder pair
It can be correctly decoded and be handled in the message that highest version terminal is sent, than as being correctly decoded out the transmission of highest version terminal
RRC CONNECTION REQUEST message and comprising IE.
S102, the RNC judge whether the terminal protocol version is higher than the highest protocol version itself supported.
After obtaining terminal protocol version by S101, technical scheme then will be to the highest version terminal of access
Access processing is carried out according to the highest protocol version that RNC can be supported, for example RNC highest supports REL-9 version, the terminal of access
For REL-11 version, then RNC is sent to end according to the message format tissue RRC CONNECTION SETUP message of REL-9 version
End waits RRC access procedure after terminal replies RRC CONNECTION SETUP COMPLETE message to complete.
S103, if so, LTE ability, the triggering reason of the access request, blind redirection of the RNC according to the UE
The adjacent area of switch and the cell of UE request access, indicates that the UE is redirected or according to the highest agreement version
Access request described in present treatment.
For in highest version terminal RRC access procedure, if the reason of triggering RRC request is PS business related causes or note
Volume, intersystem cell reselection reason, and terminal supports LTE ability, and current area is furnished with the adjacent area LTE, and RNC can received
RRC refuse information is sent after RRC access request message carries the blind redirection of LTE redirection information instruction terminal progress, this function
By RNC switch control.There is no the adjacent area LTE if being unsatisfactory for having LTE ability or current area or be unsatisfactory in RRC reason for claim
Any one, then handled by the normal access process of the RRC of the RNC highest version that can be supported.
Therefore, in the application preferred embodiment, which is based on following situations and is handled:
(1) if the UE has the LTE ability, there is the cell adjacent area LTE, the triggering reason to meet specified item
Part and the blind redirection of switches are currently open state, and the RNC is redirected to UE transmission；
(2) if the UE does not have the LTE ability or the cell does not have the adjacent area LTE or the triggering reason not
Meet specified requirements or the blind redirection of switches currently not for open state, the RNC according to the highest protocol version at
Manage the access request.
It should be noted that entering process for the reorientation in S103, the application is executed according to same procedure, RRC access
Or in the subsequent process after relocating, if terminal has LTE ability, whether RNC can match according to current service cell
LTE neighboring BS information is set, decides whether to redirect between instruction terminal trial system, relocation loading mode moves back to LTE network between system.It is right
It relocates in the RNC of highest version terminal into the highest protocol version processing supported by RNC is relocated into process.It relocates successfully
Afterwards, if terminal has LTE ability and current service cell is configured with the adjacent area LTE, 3A can be transmitted and measure control message, if
Terminal has reported the 3A measurement report for carrying LTE information, and RNC judgement is to relocate or move in a manner of redirection LTE net
Network.If RNC construction and the transparent vessel structure that the practical version of UE matches issue eNB, true by UE using relocation loading mode
Version processing relocates out process；If the highest version supported by RNC, which is sent out from RRC release message, to be taken using redirection mode
Band LTE redirection information.
In a preferred embodiment of the present application, when the RNC receives the Redirection Request message that the UE is sent, institute
It states RNC to be decoded the transparent vessel carried in the Redirection Request message, institute is then obtained according to the transparent vessel
The terminal protocol version of UE is stated, and judges whether the terminal protocol version is higher than the highest agreement version itself supported
This.Different court verdicts and process flow is as follows:
It (1), will be described according to the highest protocol version if the terminal protocol version is higher than the highest protocol version
UE access, and the UE relocate into processing after the LTE ability for the UE that is disposed.
In this case, RNC first determines whether the UE has the LTE ability, if it is judged that be yes, then
RNC saves the ability information of LTE ability, and relocate into processing to the UE after preservation；If it is judged that
Be it is no, RNC relocate into processing to the UE.
(2) if the terminal protocol version is not higher than the highest protocol version, the UE relocate into processing.
It should be noted that relocate into highest version terminal, if LTE ability and current service cell is supported to have
The adjacent area LTE sends 3A measurement control message and measures to the adjacent area LTE, if terminal has reported the measurement report of the adjacent area LTE,
RNC according to type of service judge using redirect or relocate, principle be use relocation loading mode if it is CS business, if
It is that PS business redirects or relocation loading mode can be used.After being accessed in this way for highest version terminal drop version, taken if received
It is saturating by the practical version tissue of terminal if necessary to initiate reorientation if band receives the 3A measurement report message for carrying LTE information
Message in bright container, it is only necessary to increase highest version and relocate out and handle branch, not have to add other highest version protocol processes point
Branch.
In order to which the technical idea of the application is further described, now in conjunction with specific application scenarios, to the technical side of the application
Case is illustrated.
As shown in Fig. 2, the processing flow schematic diagram of the RRC access proposed for the application specific embodiment, including following step
It is rapid:
If it is RRC request message after step a) ASN decoding, judge whether UE version is higher than the highest that current RNC is supported
Protocol version is handled by normal RRC access if being not higher than, version information is saved to UE context (UE Contex),
The side RNC sends the RRC CONNECTION SETUP message to match with access version.
If step b) is higher than the highest protocol version of RNC, handled by the highest protocol version that RNC is supported, by version
Information preservation saves LTE ability information if carrying LTE ability in RRC request to UE context (UE Contex), after
It is continuous to decide whether to need to refer to these abilities when move back to LTE network, it initiates to redirect if meeting blind redirection condition,
Otherwise it is handled by normal RRC access.
The processing of the subsequent other signaling procedures of step c) is at the protocol version that saves in UE context (UE Contex)
Reason.
As shown in figure 3, for the application specific embodiment propose system between/system in relocate into process flow signal
Figure, comprising the following steps:
The current RNC of step a) receives relocation request message, to the transparent vessel carried in message
(ToTargetRNC_Container) it is decoded.
Step b) gets the version carried in transparent vessel, compared with the protocol version that current RNC highest is supported, such as
Fruit is lower than the highest version that RNC is supported, then version information is saved into UE context by the version access carried by transparent vessel
(UE Contex)。
If carrying version in step c) transparent vessel is higher than the protocol version that RNC highest is supported, terminal is dropped
Version access, the highest protocol version distribution resource supported according to RNC, tissue switching command, version information is saved on UE
Hereafter (UE Contex), while saving the true version of UE.
Step d) is for other processes after relocating successfully, if it is relocating out and the true version of UE is effective,
Then RNC construction transparent vessel structure identical with the true version of UE is sent to Target RNC/eNB processing and relocates out process, otherwise
By the version processing in UE context.
