Detailed description of the invention

Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is carried out clear, complete Describe, it is clear that described embodiment is only a part of embodiment of the present invention rather than whole embodiments wholely.Based on Embodiment in the present invention, it is every other that those of ordinary skill in the art are obtained under not making creative work premise Embodiment, broadly falls into the scope of protection of the invention.

Radio resource control (Radio Resource Control, RRC) connection release message is initiated in cell-of-origin (RRC connection release) or RRC connection abandons message (RRC connection reject), these two message In can comprise redirection information, redirection information middle finger sets the goal community or target frequency, and UE receives above-mentioned redirection After information, release RRC connects, and returns to idle state, and searches for and attempt resident on Target cell/target frequency, if looked for To suitable persistent district, RRC connection request (RRC connection can be initiated on Target cell/target frequency Request) message.Without finding persistent district when, then at frequency at Target cell or gravity treatment Hui Yuan little District, initiates RRC connection request message again.

CCO process is initiated in cell-of-origin, and CCO order middle finger sets the goal community, if UE can not be in specifying intervalometer and mesh Mark community is successfully established RRC and connects, then return to send CCO in cell-of-origin and unsuccessfully order.

The technical problem to be solved in the present invention is that network side cannot know that UE performs to redirect or the relevant letter of community change Breath, network is optimized, and/or enters the performance of current network systems by the truth performing redirection or CCO according to UE Row statistics.

In order to solve above-mentioned technical problem, the invention provides following technical scheme.

Embodiment in the present invention occurs as a example by different standards with CCO to redirect, but can be used for same In individual wireless standard.

The target frequency such as redirecting order/CCO and the cell-of-origin initiating redirecting signaling broadly fall into UMTS or all Belong to LTE, or broadly fall into GERAN, CDMA etc..

Embodiment one

Fig. 1 is the schematic flow sheet of the information recording method of the embodiment of the present invention one.As it is shown in figure 1, this information recording method Method comprises the following steps:

101, UE receive redirection instruction or the Cell Change Order that first network node sends；Wherein, described redirection Instruction or Cell Change Order are used for indicating UE and the second network node to set up communication connection；

102, described UE perform to redirect or community change, and record redirection information or community modification information；

103, described UE report described redirection information or community modification information.

Wherein, first network node and the second network node can be the different wireless access that different radio accesses standard Network node, can be the different wireless access network node of same wireless access standard, can be that same wireless accesses system The different frequent points of formula, it is also possible to be the different community of same wireless standard.If first network node and the second network node Being the different wireless access network node of the most collinear access standard, redirection information (redirection info) can comprise Connect at wireless heterogeneous networks and abandon (RRC connection reject) or wireless heterogeneous networks connection RRC In connection release message.If first network node and the second network node are same wireless accesses standard not Same wireless access network node or the different community of same wireless standard, redirection information be (the second network node Frequency point information or cell scrambling information) may be embodied in RRC reconfiguration message that (such as, radio bearer reconfigures, transmission letter Road reconfigures, and physical channel reconfigures etc. in message).

In the information recording method of the present embodiment, it is that different radio accesses system with first network node and the second network node Illustrate as a example by the different wireless access network node of formula.That is: UE receives from the community of the first wireless access technology RAT 1 Redirect instruction or Cell change order order after, it is desirable to UE enter into RAT 2 set up connection this during, UE performs to redirect or perform Cell Change Order success to from RAT 1, is successfully established the information note that RRC is connected with RAT 2 Record, or perform to redirect or perform the Cell Change Order information record to RAT 2 failure from RAT 1.Referred to herein as RAT can be EUTRAN, CDMA2000, GERAN and WiMAX, the various standard network such as WiFi, WCDMA, TD-CDMA.

Hereinafter, RAT 1 is referred to as source RAT, RAT 2 is referred to as target RAT.

Specifically, Fig. 2 is the system schematic of the information recording method for realizing the embodiment of the present invention one.Such as Fig. 2 institute Show, the first community Cell 1 and the second community Cell 2 be frequency be the UMTS (Universal of f1 Mobile Telecommunications System, UMTS) community, the 3rd community Cell the 3, the 4th community Cell 4 and 5th community Cell 5 be frequency be the community of Long Term Evolution (Long Term Evolution, the LTE) system of f2, the 6th is little District Cell 6 be frequency be f4 global system for mobile communications (GSM)/enhanced data rates for gsm evolution technology (EDGE) is wireless The community of access network (GERAN), seven cell Cell 7 be frequency be the community of the GERAN of f3.Wherein, to reside in the 4th little for UE District cell 4.

When UE initiates CSFB business, network side illustrates as a example by UE redirects this scene below, this scene It is used only as an example, the not restriction to the present embodiment technical scheme, the redirection of such as PS business or Cell Change Order Deng being all applicable to the present embodiment.

The 4th community cell 4 of LTE redirects in instruction at the inter-RAT being sent to UE, the frequency that instruction UE redirects Rate is f4, and using the system information of certain community (for example, first community cell 1) in target RAT as auxiliary information It is supplied to UE.UE response inter-RAT redirects instruction, redirects process, and according to preset rules, record redirects phase Pass information.Wherein, redirect instruction and be such as included in radio resource control (Radio Resource Control, RRC) Connection release message (RRC connection release) or RRC connection abandon message (RRC connection reject) In.

UE redirects relevant information by record and record information is supplied to network side, can realize network and carry out inter- The optimization of RAT interoperability and the time delay of statistics UE CSFB and success rate etc..

Specifically, the system information that auxiliary information is the first community cell 1 that such as network side provides.When UE performs weight During orientation, be redirected to first community cell 1 failure, and be redirected to the second community cell2 (the 3rd network node, the 3rd Network node and first network node and the second network node can be the different wireless access networks that different radio accesses standard Network node, can be the different wireless access network node of same wireless access standard, can be that same wireless accesses standard Different frequent points, it is also possible to be the different community of same wireless standard.This sentences the 3rd network node is to save with first network Illustrate as a example by the different wireless access network node of point and the second network node different radio access standard), i.e. network The system information of the first community cell 1 that side provides does not has help for the redirection of UE.At this moment UE is by this situation Recording and be supplied to network side, network side just can be analyzed and know the auxiliary information of offer improper, it should carry to UE For the system information of the second community cell 2, accelerate UE and access.Further, if UE will start to success from initiating CSFB business The connection carrying out CS territory terminates to record during this period of time, and network side can also add up the time delay of UE CSFB easily.

Wherein, if redirecting, this time delay can also be from receiving instruction Connection Release/RRC connection Radio resource control (Radio Resource Control, RRC) release message (RRC the release)/RRC of reject Connection reject starts, and successfully establishes RRC and connects to UE with cell2, i.e. it is complete that UE has sent RRC connection establishment Become message during this period of time.If cell change, this time delay can be to receive " mobility from EUTRA from UE Command " order starts to UE successfully to establish RRC connect with the second community cell 2, it is simply that and UE has sent RRC connection and has built Vertical completion message is during this period of time.

If CCO, UE can receive CCO order from cell-of-origin starts record, until in UE success and CCO order Target cell/target frequency is set up RRC and is connected during this period of time；Or until UE judges CCO failure, cell-of-origin sends CCO Failure is during this period of time.

If the record under CCO scene, UE can and little on Target cell in CCO order or target frequency District be successfully established RRC connect time or be successfully established RRC connect after, in Target cell or in the community of target frequency on State record information reporting to network side；Or

If CCO failure, UE cannot be successfully established RRC with the community of Target cell or target frequency and be connected, then UE exists After returning to cell-of-origin or origin system node, unsuccessfully order or in other message at CCO, above-mentioned information reporting is given and sends out Play the cell-of-origin/origin system of CCO flow process.

(8) cell reselection (Cell reselection) track record；

Specifically, cell reselection keeps track of and such as includes following information:

Scene description, such as scene are that " LTE is redirected to UMTS " (this scene is only used as example, not for applicable field The restriction of scape):

Assume that the UE being initially in connection status receives the instruction of RRC Connection Release from LTE community 1 or community change refers to Show UMTS.

UE connection status from LTE first discharges connection and enters idle state, then performs community and choose UMTS, arbitrarily One applicable resident community meeting S criterion is initiated RRC and is set up connection request；

UE initiates after Article 1 RRC sets up connection request, to wait that network side replys RRC connection establishment message in umts (RRC connection setup)；

Special screne describes, any one in for example, following six kinds of scenes of special screne:

Special screne 1:UE is waiting during RRC connection setup if it occur that cell reselection or T300 (Transmission of RRC CONNECTION REQUEST in case of connection establishment For reasons other than MBMS reception) or T318 (Transmission of RRC CONNECTION REQUEST in case of connection establishment for MBMS reception) expired；

Special screne 2: RRC connection setup complete message (RRC connection setup complete) is passed at UE Before sending to UE bottom, there occurs cell reselection；

After the RRC connection setup message that special screne 3:UE receives, according to RRC connection setup Physical channel failure is set up in configuration parameter in message and current area；

In the RRC connection setup message that special screne 4:UE receives, it is intended that UE enters CELL_FACH state And network specifies UE to enter frequency (frequency) A, UE not find the most resident community on frequencyA, but Suitable community is have found on frequency B；

In the RRC connection setup message that special screne 5:UE receives, it is intended that UE enters CELL_FACH state And network appointment UE enters Target cell (main scrambler), but UE have selected another community；

In the RRC connection setup message that special screne 6:UE receives, it is intended that UE entrance CELL_FACH state, And network allocation to UE Cell Radio Network Temporary Identifier/Identity, Cell-RNTI (Cell Radio Network Temporary Identifier, And HSDPA system wireless network temporary mark (H-RNTI) is empty C-RNTI)；

When above-described any special screne occurs, UE can carry out record to above-mentioned special screne, and perform with Lower judgement:

UE checks that (V300 is the RRC connection request that record UE has sent to oneself internal counter V300 Number of times) whether less than N300 (the defined maximum times sending RRC connection request of network), if V300 Less than N300, and UE there occurs cell reselection, then UE can retransmit RRC connection in the new cell Request, and increase V300, restart T300；Otherwise it is assumed that this time RRC sets up procedure failure, enter Idle state.

Additionally, when above-described any special screne occurs, UE can also record one of following information or multiple Combination:

When V300 adds 1 every time, retransmit and send the RRC reason of connection request；

If UE is successfully established RRC in Cong Yuan RAT community to target RAT community, connection (also will RRC connection Setup complete sends to bottom) during, it is assumed that once there is cell reselection in UE, can going through with recording cell gravity treatment History, i.e. path.

In addition in the present embodiment, UE performs, according to network instruction, the situation that record operates, UE can also be described in execution When inter-RAT redirects or described inter-RAT community is changed, automatically start record operation, record inter-RAT and redirect Information or inter-RAT community modification information.Specifically, UE can according to receive network side instruction UE carry out RRC reorientation Or during the instruction message of cell change, start the process of record, such as receive the load balancing that reason is CSFB or TAU of mark RRC connection release message time, start record process.

In the present embodiment, respectively redirection failure and two kinds of situations of cell change failure are illustrated.

One, redirect unsuccessfully

The failure redirected such as is defined as any one in scenario described below: auxiliary information and UE that network provides finally connect Connecing successful information inconsistent, such as source RAT network instruction UE connects in frequency 1, but UE does not connect in frequency 1 Success, is ultimately connected to frequency 2；Or, network provides the system information of the first community cell 1, but UE is ultimately connected to On second community cell 2；Or UE has exceeded time T and has just been connected to network, and wherein time T is such as specified by network or at UE In pre-set.Or, further, when first network node initiates the Target cell being redirected to the second network node, weight Directed information carries the system broadcast message of the Target cell of the second network node；UE use obtains from redirection information The system broadcast message of the second network node attempts accessing Target cell failure；UE saves from the 3rd network node or first network Point, when initiating to access, UE notice is from the 3rd network node or first network node, and what first network node was initiated is redirected to Second network node failure.Concrete failure cause can be carried further, such as, may is that use obtains from first network node The system broadcast message of Target cell access the second network node failure.

Further, Radio Link Failure (RLF) report, after redirecting unsuccessfully, also can be extended by UE, RLF report acceptance of the bid weight sensing orientation reason.Such as, UE has initiated to redirect due to CSFB, but finally redirects failure, then UE exists In RLF report, the current reason redirected of mark is CSFB.

Two, cell change (CCO) failure

When UE is under the CCO order of source RAT network, carry out cell change process, CCO wherein carries the frequency of target RAT Point or the information of community.If the target RAT/ community that UE can not indicate in source RAT network before T309 is expired is carried out even Connect foundation, then judge CCO failure, return back in the RAT of source send CCO failed message.

UE carries out record to CCO process:

(1) the most successful and Target cell/target before intervalometer (for CCO from UMTS, can be T309) time-out Frequency/target RAT is set up RRC and is connected；

(2) in Target cell/target frequency/target RAT random access procedure failure, such as due to RACH (Random Access Channel, RACH) is congested；

(3) RRC connection establishment failure in Target cell, does not such as receive RRC connection at Target cell Setup or MAC conflict contention resolved failure)；

(4) at Target cell/target frequency/target RAT access phase, the random number that UE oneself generates is less than " ac- Barring Factor " parameter, thus UE thinks that Target cell is not for entering community；

(5) Access Control in the system broadcast message of Target cell/target frequency/target RAT be designated as " forbidding " or Person " reserves "；

(6) receive RRC connection in Target cell/target frequency/target RAT and abandon message (RRC Connection Reject)；

(7) receive RRC in Target cell/target frequency/target RAT and connect weight release message (RRC Connection Rerelease)；

(8) RRC connection release message is received and from RRC connection release message in Target cell/target frequency/target RAT The load balancing of the release cause of middle acquisition, for example, TAU, CSFB or CSFB high priority etc.；

(9) non-access (NAS) layer of UE is indicated to access (AS) layer, abandons RRC connection establishment process；

(10) UE and which community attempt having carried out the community ID of RRC connection establishment；

(11) during the RRC connection establishment of target RAT or Target cell, the intervalometer of startup is expired or stops Cause the failure of RRC connection establishment, intervalometer for example, T300, T302, T303 or T305 etc..

UE, after cell change failure, can send CCO failed message in source RAT network, and indicate in CCO failed message The reason rebuild is one of above-mentioned reason or multiple combination.
