The processes such as reassignment.General process can be carried out independently, can also be carried out with the special process of GMM.
It should be noted that ATTACH processes are exactly to adhere to enrollment process, each starting up of terminal establishes PS letters with network
After order connection, it is necessary to carry out ATTACH registration processes, it is established that the upper and lower text of GMM, the function of such ps domain could be normal
Use.
That is, complete wireless heterogeneous networks (RRC, Radio Resource Control) even in terminal and network
When connecing, terminal carries out GMM attachment flows with network side, i.e., the first attachment that network side receiving terminal is sent to WCDMA cells please
Seek message.
It should be noted that in embodiments of the present invention, attaching process is initiated by UE all the time, for example, UE is triggered when starting shooting,
Or UE leaves the network coverage for a period of time, then need to adhere to again.And the work of attaching process can include：Terminal and network
The mutual authentication of side, UE and GMM establish MME contexts；GMM establishes default bearing for UE；UE is with obtaining the IP of network side distribution
Location；Terminal positional information is registered；Distribution of temporary identifications etc..And UE sets out, the avatar of attachment flow is：Terminal, i.e.,
UE sends Attach Request message to network side, in embodiments of the present invention, when being connected with terminal RRC, network side receiving terminal
The first Attach Request message sent to WCDMA cells, proceeds by attachment flow.
In embodiments of the present invention, the premise for attaching process being performed between terminal and network side is that terminal is completed with network
Process is established in RRC connections.I.e. before S101, network receiving terminal is registered to RRC connections transmitted during WCDMA cells please
Message is sought, completes the RRC connection flows of terminal.
Specifically, terminal sends RRC connections to network side and establishes request message；The lateral terminal of network returns to RRC connections and builds
Vertical response message；Terminal sends RRC connection setup complete messages to network side.
Exemplary, (1), UE send RRC connection request message RRC CONNECTION REQUEST by uplink CCCH,
A RRC connection is established in request.(2), RNC is established special in UE according to the reason for RRC connection request and system resource state
With on channel, and distribute RNTI, Radio Resource and other resources (L1, L2 resource).(3), RNC sends Radio Link to NodeB
Establish request message RADIO LINK SETUP REQUEST, the specific radio link money needed for request NodeB distribution RRC connections
Source.(4), after NodeB resources prepare successfully, to RNC response wireless link response message RADIO LINK SETUP
RESPONSE.(5), RNC establishes the transmission carrying of Iub interface user plane using ALCAP agreements, and completes between RNC and NodeB
Synchronizing process.(6), RNC sends RRC connections to UE by downlink CCCH channels and establishes message RRC CONNECTION SETUP,
Message includes the dedicated channel information of RNC distribution.(6), after UE confirms that RRC connections are successfully established, in the uplink just established
DCCH channels send RRC connection setup complete message RRC CONNECTION SETUP COMPLETE to RNC.RRC connections are established
Process terminates.
In embodiments of the present invention, ATTACH processes mainly have following two.(1), normal GPRSATTACH processes, this
The IMSI for being used for ONLYGPRS business in the case of kind process network operator scheme I or network operation mode II by UE is attached
.(2), the GPRSATTACH processes of combination, the GPRS of COMBINED and non-gprs service are supported during for network operation mode I
Attaching process.
In embodiments of the present invention, the first Attach Request message can be Gmm Attach Request.
It is to be appreciated that either any ATTACH processes are all initiated by UE ends.When network receives UE hairs
ATTACHREQUEST message, GMMauthenticationand ciphering are initiated by the message in REQUEST
procedure.If the authentication parameter of network and UE match, authentication ciphering process is by the way that then network will send ATTACH
ACCEPT message simultaneously distributes new GMM message parameters；If parameter mismatches, authentication process failure, can trigger GMM with that
identification procedure。
It should be noted that in embodiments of the present invention, before establishing rrc connection, network configuration WCDMA cells
SIB1 is NOM1, NetworkOperationMode 1, activates WCDMA cells, and so ability triggering terminal is established with network
RRC connections, and carry out attach request to WCDMA cells.Wherein, Fig. 4 is to show showing for SIB1 by computer display
It is intended to.
That is, the embodiment of the present invention is the place in the attachment flow when the network operation mode of WCDMA networks is 1
Reason mode.
S102, send the first attachment refuse information to terminal, and discharges the RRC connections for terminal, wherein, the first attachment
At least instruction terminal does not allow mobile data services in current PLMN in refuse information.
WCDMA networks are after the first Attach Request message that receiving terminal is sent to WCDMA cells, WCDMA networks (tool
WCDMA networks under the emulated network environment of body position) receive the first Attach Request message after, can be by emulation platform come real
Now the first attachment refuse information is issued to terminal.
It should be noted that if WCDMA networks receive this time to adhere to, an ATTACHACCEPT message will be sent,
By comprising new various parameters in message, after UE is received, send ATTACHCOMPLETE and confirmed, ATTACH processes are successful
Terminate, the upper and lower texts of GMM are established.If network refusal attachment, sends ATTACHREJECT message.The reason for network refusal attachment
There are illegal UE, packet wireless service (GPRS, General Packet Radio Service) service not to allow, GPRS and non-
GPRS services do not allow, PLMN does not allow, position area does not allow, roam do not allow, the cell that is not adapted to etc., for each
Kind situation, UE can be handled accordingly according to the reason for refusal.
Wherein, in embodiments of the present invention, the attachment refusal in the case that WCDMA network analogs PLMN does not allow, encapsulation
The reason for first attachment refuse information, first, which adheres in refuse information the reason for carrying connection failure, is worth, connection failure is worth to work as
Preceding PLMN does not allow mobile data services.

Area performs attaching process.The reason in the present embodiment, the current PLMN of value characterization did not allowed mobile data services, specific numerical value sheet
Without limiting in embodiment.
During practical application, in order to verify the validity of prioritization scheme, after attachment refuse information can be received with detection terminal
Behavior, further to verify the validity of prioritization scheme and reasonability.
Exemplary, abnormal, hair is replied in the Gmm Attach Request requests that UE is then initiated in emulation platform simulation
Gmm Attach Reject (the first attachment refuse information) have been sent to terminal." reason is being encapsulated in Gmm Attach Reject "
Cause values for " GPRS service not allowed in this PLMN ", here, " GPRS service not
The reason for allowed in this PLMN " representative attachment failures is that GPRS services are not allowed by current PLMN, i.e., current PLMN
Do not allow mobile data services.Fig. 5 is the schematic diagram of the cause values shown by computer display.
S103, after the first duration, do not receive the second Attach Request message that terminal is re-initiated to WCDMA cells
When, detect whether the login request message that receiving terminal is sent to LTE cells, determine whether terminal successfully connects based on testing result
Enter LTE network.
In embodiments of the present invention, in the present embodiment, terminal disappears in the first attachment refusal for receiving carrying cause value
After breath, unregistered state can be in, at this time, can be shown as " unregistered in the user interface (UI, User Interface) of terminal
State ".Also, it may attempt to re-initiate the second attach request after the first attachment refuse information has been sent to terminal,
Therefore, T3245 carries out timing at set time intervals, and before timing terminates, network detects whether to receive terminal
The second Attach Request message re-initiated to WCDMA cells, if just release RRC connections, detection not after timing
Whether the login request message that receiving terminal is sent to LTE cells, such as proceed by a series of incoming streams such as RRC connections
Journey.That is, after the first duration, when not receiving the second Attach Request message that terminal is re-initiated to WCDMA cells,
Whether the RRC sent to LTE network establishes request message RRC Connection Request to detection terminal.
It should be noted that in order to which triggering terminal sends RRC Connection Request, the present embodiment to LTE network
The transmission power of LTE network after the access state for detecting terminal is unregistered state, can also be improved, that is, it is small to increase LTE
The transmission power in area.
In embodiments of the present invention, determine that the process whether terminal is successfully accessed LTE network can be based on testing result：
When receiving login request message, the reason for claim value carried in login request message is obtained；When reason for claim value characterization is exhaled
When being signaling, whether verification user face data is unobstructed, and the speed for being specially user face data of the detection terminal under LTE network is
It is no to be more than or equal to predetermined threshold value；If the speed of user face data of the terminal under the LTE network is more than or equal to predetermined threshold value,
Characterization terminal is successfully accessed LTE network；If the speed of user face data of the terminal under LTE network is less than predetermined threshold value, table
Sign terminal does not access LTE network.
Here, after detecting in the first duration, the second attachment that terminal is re-initiated to WCDMA cells is not received
During request message, the reason for claim value carried in the login request message that detection receiving terminal is sent to LTE cells is default original
During because of value, illustrate prioritization scheme success, coordinate establish defaultEPSBearer at this time, and then verify that user plane data transfer is smooth
It is logical.
In embodiments of the present invention, cause value is preset to be used to characterize call signaling.That is, when reason for claim value characterizes
During call signaling, illustrate prioritization scheme success, coordinate establish defaultEPSBearer at this time, and then verify that user face data passes
It is defeated unimpeded.
Further, after the reason for claim value carried in obtaining login request message, when reason for claim value characterization is exhaled
When crying data service, illustrate that prioritization scheme fails, characterization terminal does not access LTE network.
In embodiments of the present invention, call signaling can be MO signalling, and call data business can be MO
data。
Exemplary, emulation platform is simulated after timer, the RRC Connection then initiated UE
Connection is established in Request requests." package request reason cause values are " MO in RRC Connection Request "
Signalling ", here, " it is to establish call signaling that MO signalling ", which represent request and establish the reason for connecting,.
It is understood that terminal performs the access procedure of LTE network using default prioritization scheme, since UE is initial
Access during the ps domain of WCDMA networks and abnormal failed authentication occur and network refusal access, and cause UE to cause whole PLMN
Other RAT fail, and under this abnormal scene, terminal can re-initiate registration request when running into above-mentioned abnormal causation value and disappear
Breath, completes UE access LTE network, the validity and reasonability of prioritization scheme based on obtained access result verification, for into one
Step improvement and optimization scheme provides foundation, so as to improve the accuracy of the network optimization.
