The characteristics of in order to more fully hereinafter understand the embodiment of the present invention and technology contents, below in conjunction with the accompanying drawings to this hair
The realization of bright embodiment is described in detail, appended attached drawing purposes of discussion only for reference, is not used for limiting the embodiment of the present invention.
In the technical solution of the embodiment of the present invention, a kind of abnormal access scene is simulated, i.e.,：Terminal is reset from LTE network
During to GPRS network, access GPRS network failure (gprs service is unavailable), causes terminal can not be back to LTE network.
For above-mentioned abnormal access scene, the process in end side using the execution LTE network access of default prioritization scheme,
And whether detection terminal is successfully accessed LTE network, the validity and reasonability of prioritization scheme used by final definite terminal.
In the embodiment of the present invention, a network environment (being known as emulated network environment) can be constructed by emulation platform, is imitated
True network environment includes at least following network structure：LTE network, GPRS network, wherein it is possible to be configured in the SIB of LTE network
GPRS neighboring BS information, configures LTE neighboring BS information in the SI of GPRS network；Alternatively, can also be configured in the SIB5 of LTE network
TDSCDMA neighboring BS information, can also configure GSM neighboring BS information in the SIB7 of LTE network.Fig. 1 is to pass through Computer display screen display
Show the schematic diagram of SIB5, Fig. 2 is the schematic diagram that SIB7 is shown by computer display.
Then, the network environment based on construction performs LTE network access procedure, is arrived involved in LTE network access procedure
Main object include terminal and network, wherein, terminal can with but be not limited to realize using mobile phone, network can use imitative
True platform is realized.Here, since network is realized using emulation platform, thus this network can stablize reproduction and terminal it
Between abnormal access scene, so as to verify the feasibility and stability of prioritization scheme.
That is, the scene where terminal described in the embodiment of the present invention is obtained by emulation mode, so handle,
On the one hand, staff need not remove Site Detection, so as to reduce personnel cost；On the other hand, have can for live scene
Other factors can be further comprises, so as to influence testing result, so using the artificial network of the embodiment of the present invention, can be stablized multiple
The abnormal scene that existing field network occurs, can eliminate the other factors under the described scene of the embodiment of the present invention and detection is tied
The influence of fruit.
Based on above-mentioned emulated network environment, the technical solution of the embodiment of the present invention is described in detail below.
Fig. 3 be the embodiment of the present invention network insertion result detection method flow diagram, the technology of the present embodiment
During scheme is applied to terminal using the execution LTE network access of default prioritization scheme, as shown in figure 3, the LTE network
The detection method of access result comprises the following steps：
Step 301：The first Attach Request message that the terminal is sent is received, sending attachment receiving to the terminal disappears
Breath；First Attach Request message is sent after the terminal selects LTE cells.
In practical application, the first Attach Request message can be received by LTE network, be sent when LTE network receives terminal
The first Attach Request message after, can be terminal establish default EPS bearing, to complete attaching process；Sent to the terminal
Adhere to received message.
It is worth noting that, it is that terminal completes nothing with network that the premise of attaching process is performed between terminal and LTE network
Process is established in line resources control (RRC, Radio Resource Control) connection.
Specifically, terminal sends RRC connections to LTE network and establishes request message；Network returns to RRC connections to terminal and establishes
Response message；Terminal sends RRC connection setup complete messages to network.
Alternatively, in emulated network environment, the first Attach Request message can be sent with network-triggered terminal, so that eventually
End is registered to LTE cells；For example, by controlling the transmission powers of LTE cell own base stations the LTE that terminal receives can be made small
The signal strength of area's signal is more than signal strength threshold, and then triggering terminal is registered to LTE cells；Here, signal strength threshold
Represent the minimum value of the signal strength of LTE cell signals required during terminal access LTE cells.
Alternatively, can be with the user plane between detection terminal and LTE network after default EPS bearing is established for terminal
Whether data are unobstructed, when the user face data between terminal and LTE network is unobstructed, perform step 302；Otherwise, can terminate
Flow.
For example, the speed of the user face data when terminal under LTE network is more than or equal to predetermined threshold value, illustrate terminal with
User face data between LTE network is unobstructed；When the speed of user face data of the terminal under LTE network is more than or equal to default threshold
Value, illustrates that the user face data between terminal and LTE network is obstructed.
Here, predetermined threshold value can be configured as needed.
Step 302：Sent to the terminal and redirect order, the redirection order is used to indicate the terminal access
GPRS network.
In practical applications, LTE network can issue redirection (RRC Connection with actual demand to terminal
Release) order, GPRS subdistrict frequency point information can be carried in order is redirected；In this way, when terminal receives redirection life
After order, GPRS subdistrict frequency points information request access GPRS network can be based on.
GPRS is a kind of available mobile data services of gsm mobile telephone user, belongs to the number in Generation Mobile Telecommunication System
According to transmission technology；GPRS can say be GSM continuity.GPRS with the past it is continuously different in the mode of channel transmission, be with package
(Packet) formula is transmitted, therefore the expense that user is born is calculated with its data transmission unit, not whole using its
Channel, in theory inexpensively.The transmission rate of GPRS can be promoted to 56 even 114Kbps.
In practical application, GPRS is to increase new network entity on the basis of GSM network to realize Packet data service,
The network entity that GPRS is increased newly includes：GPRS Support Node (GSN, GPRS Support Node), packet control unit (PCU,
Packet Control Unit), borde gateway (BG, Border Gateways), charging gateway (CG, Charging
Gateway), name server (DNS, Domain Name Server) etc.；Wherein,
GSN is most important network components in GPRS network, can be divided into Serving GPRS Support Node (SGSN, Serving
GPRS Support Node) and GPRS gateway support node (GGSN, Gateway GPRS Support Node) two types,
The main function of SGSN is the current location information for recording terminal, there is provided mobile management and Route Selection etc. service, and
Sending and receiving for mobile packet data is completed between terminal and GGSN；GGSN plays gateway effect, the packet count in GSM network
Protocol conversion is carried out according to bag.
PCU is used to handle data service, and data service is separated from GSM speech businesses.PCU adds packet
Function, can control Radio Link, and allow multi-user to take same Radio Resource.
BG is for GPRS backbone networks between public land mobile network (PLMN, Public Land Mobile Network)
Interconnection, the main routing function for completing to adhere to separately between SGSN, GGSN of different GPRS network, and security management function, this
Correlation function can also be increased according to the Roaming agreements between operator outside.
CG is mainly completed to collect from the ticket of each GSN, merged, pretreatment work, and as between GPRS and charging center
Communication interface.
DNS is divided to for two kinds, the first DNS be GGSN with the DNS between external network, major function is to external network
Domain name is parsed；Second of DNS is the DNS on GPRS backbone networks, and major function is in packet data protocol (PDP, Packet
Data Protocol) in context activation Procedure according to definite access point name (APN, Access Point Name) parsing
Go out the IP address of GGSN, and during the Routing Area Update between SGSN, according to former Route Area number, parse former SGSN's
IP address.
Step 303：The second Attach Request message that the terminal is sent is received, sending attachment refusal to the terminal disappears
Breath；Second Attach Request message is sent after the terminal selects GPRS cells.
It is understood that after terminal receives redirection order, the second Attach Request message can be sent to network；
In practical application, terminal, can be to network channel request (Channel when initiating the attaching process based on GPRS cells
Request) message；Further, terminal can also send GPRS when initiating the attaching process based on GPRS cells to network
The request of mobile management Routing Area Update (GPRS Mobility Management Route Area Update Request,
GMM RAU Request) message.
Specifically, when terminal initiates the attaching process based on GPRS cells, GPRS attach requests is sent to SGSN first and are disappeared
Breath, carries international mobile subscriber identity (IMSI, International by the terminal in the Attach Request message
Mobile Subscriber Identification Number) and temporary logical link identifier (TLLI, Temporary
Logical Link Identifier)；SGSN will ask counterpart terminal when receiving the Attach Request message of terminal to GGSN
IMSI authenticate three elements；SGSN is authenticated with terminal interaction, and after the authentication is passed, SGSN sends location updating to GGSN and disappears
Breath；After the user data of terminal is sent to SGSN by GGSN, location updating confirmation message is replied to SGSN；SGSN is to terminal replies
Adhere to received message, the TLLI reported by terminal is carried in the attachment received message.
When terminal carries out Routing Area Update in the gprs networks, Routing Area Update request is sent to new SGSN first
(Routing Area Update Request) message；New SGSN (new SGSN) sends SGSN to former SGSN (old SGSN)
Context query asks (SGSN Context Request) message, and former SGSN replys SGSN Context query responses to new SGSN
(SGSN Context Response) message；New SGSN sends context response (SGSN Context to former SGSN
Acknowledge) message, former SGSN reply data forwarding (Forward Packets) message to new SGSN；New SGSN is to GGSN
Renewal PDP Context request (Update PDP Context Request) message is sent, GGSN replys renewal PDP to new SGSN
Context response (Update PDP Context Response) message；New SGSN is to attaching position register (HLR, Home
Location Register) send location updating (Update Location) message；HLR sends delete position to former SGSN
(Cancel Location) message, former SGSN send delete position response (Cancel Location Ack) message to HLR；
HLR sends insertion user message (Insert Subscriber Data) to new SGSN, and new SGSN replys insertion user to HLR and disappears
Cease response (Insert Subscriber Data Ack)；HLR sends more new position response (Update to new SGSN
Location Ack)；New SGSN is deposited to mobile switching centre (MSC, Mobile Switching Center)/vision location
Device (VLR, Visitor Location Register) sends location area updating request (Location Update Request)
(circuit domain) message, MSC/VLR reply location area updating to new SGSN and receive (Location Update Accept) message；Newly
SGSN sends Routing Area Update to terminal and receives (Routing Area Update Accept) message, and terminal is replied to new SGSN
Routing Area Update completes (Routing Area Update Complete) message；So far, Routing Area Update flow is completed.
Alternatively, when the true directional terminals of network send attachment refuse information, attachment refuse information can also be encapsulated, is adhered to
The reason for attachment refusal is carried in refuse information is worth, and the reason for adhering to refusal value is used to characterize the reason for adhering to refusal；
Wherein, the reason for attachment in the attachment refuse information is refused (cause) value is used to trigger the terminal
Attaching process is performed based on the LTE cells.
The reason for not refusing in the embodiment of the present invention attachment value is defined, and exemplarily, adheres to the reason for refusing
Value can be GPRS Service Not allowed, and expression does not allow terminal to use gprs service.
Step 304：The behavior of the terminal is detected, obtains the first testing result；Determined based on first testing result
Whether the terminal is successfully accessed LTE network.
Here, detecting the behavior of the terminal can be：Detect whether the terminal asks access LTE network, Yi Ji
The user face data between the terminal and the LTE network is detected after the terminal access LTE network.
In one embodiment, when detecting the terminal in preset duration and not initiating the RRC companies to the LTE cells
When meeting request (RRC Connection Request), determine that the terminal fails and access LTE network, illustrate prioritization scheme
Failure.
In one embodiment, when detecting that the terminal initiates the RRC connections to the LTE cells in preset duration
, can be by completing RRC connection building process with interacting for the terminal during request；Afterwards, LTE network can be utilized to receive eventually
What end was sent is used to ask after accessing the Attach Request message of the LTE cells, afterwards, is sent out using LTE network to the terminal
Attachment received message is sent, and detects the user face data between the terminal and the LTE network, obtains the second testing result.
Determine whether the terminal is successfully accessed LTE network based on second testing result.
Exemplarily, the second testing result is used to represent that the user face data between the terminal and the LTE network is
It is no unobstructed, that is to say, that can to determine that terminal is by verifying whether the user face data between terminal and LTE network is unobstructed
It is no to be successfully accessed LTE network.
Specifically, judge whether the speed of user face data of the terminal under LTE network is more than or equal to predetermined threshold value.
If the speed of user face data of the terminal under LTE network is more than or equal to predetermined threshold value, it is determined that described
Terminal is successfully accessed the LTE network, illustrates prioritization scheme success；If user face data of the terminal under LTE network
Speed be less than predetermined threshold value, it is determined that the terminal fails the access LTE network, illustrate prioritization scheme failure.
Here, predetermined threshold value can be arranged as required to.
During practical application, the preset duration can be realized by way of setting timer；Specifically, timing is set
Device, whether detection terminal initiates the RRC connection request to the LTE cells before the timer expiry.Wherein, timing is set
The purpose of device is to avoid the overlong time of detection.
Wherein, the duration of timer can be arranged as required to.
Alternatively, it is the network in the emulated network environment with the network of the terminal interaction.
Method provided in an embodiment of the present invention, during terminal performs LTE network access using default prioritization scheme,
The first Attach Request message that the terminal is sent is received, attachment received message is sent to the terminal；First attachment please
Seeking message is sent after the terminal selects LTE cells；Sent to the terminal and redirect order, the redirection order is used
In described terminal access general packet radio service (GPRS, the General Packet Radio Service) network of instruction；Connect
The second Attach Request message that the terminal is sent is received, attachment refuse information is sent to the terminal；Second attach request
Message is sent after the terminal selects GPRS cells；The behavior of the terminal is detected, obtains the first testing result；Based on institute
State the first testing result and determine whether the terminal is successfully accessed LTE network, can using scheme provided in an embodiment of the present invention
When network refusal terminal is redirected to GPRS network, the behavior of detection terminal, so that it is determined that whether terminal is successfully accessed LTE nets

In addition, be the network in emulated network environment with the network of the terminal interaction, need not by the way of emulation
Staff goes to scene, and can remove the factor of other influences detection, so, it is possible to substantially reduce personnel cost, meanwhile, energy
Enough eliminate influence of the other factors to testing result under the described scene of the embodiment of the present invention.
The present invention is described in further detail again with reference to an Application Example.
In this application embodiment, the emulated network environment of above-mentioned record is constructed by emulation platform, the artificial network ring
Border includes：1 LTE cell and 1 GPRS cell, the LTE cells can be TDD-LTE cells；Wherein, in the SIB of LTE network
Middle GP configuring RS neighboring BS information, configures LTE neighboring BS information in the SI of GPRS network.TDD-LTE cells and GPRS cells are matched somebody with somebody
It is set to identical PLMN ID.
Wherein, PLMN refers to：By government or operator that it is ratified, land mobile business purpose is provided for the public
And the network established and managed.During practical application, PLMN is generally set by operator.PLMN by mobile national number (MCC,
Mobile Contrary Dode) and mobile network No. (MNC, Mobile Net Code) composition, wherein, MCC uniquely represents mobile
The belonging country of user, Chinese MCC are 460；MNC uniquely represents that the network in the country, such as China Mobile GSM net are
00, China Unicom GSM net are 01.
The abnormal scene of this application embodiment is：Terminal from LTE network be redirected to GPRS network when, access GPRS network
Failure (gprs service is unavailable), causes terminal can not be back to LTE network；Detect in such a scenario based on access assessment
The validity and reasonability of this prioritization scheme of net scheme are searched across RAT.
Wherein, in a timer involved in this application embodiment, it is named as timer 1.
The detection method of this application embodiment network insertion result, comprises the following steps：
Step A1：Trigger UE starts and start register flow path to LTE cells.
Specifically, it is corresponding to LTE cells to send RRC connection request (i.e. RRC Connection Request) message by UE
Base station, after base station receives the RRC Connection Request message of UE transmissions, completes RRC with UE and is connected foundation (RRC
Connection Setup) flow.
Further, after RRC connection building process is completed, default EPS bearing is established for terminal；Alternatively, can be with
Whether the user face data between detection terminal and LTE network is unobstructed, when the user face data between terminal and LTE network is unobstructed
When, perform step A2；Otherwise, flow can be terminated.
Step A2：Analogue system improves the transmission power of GPRS cell own base stations, and issues redirection using LTE network
Order, indicates UE access GPRS cells in order is redirected.
Step A3：Analogue system GSM cell receive UE initiation channel request (Channel Request) message and
GPRS Mobility Management Routing Area Update asks (GPRS Mobility Management Route Area Update
Request, GMM RAU Request) message.
It is understood that after UE receives redirection order, can be to network channel request (message and GPRS
Mobile management Routing Area Update request message.
Here, a kind of abnormal refusal situation is simulated by emulation platform at this time, GPRS Mobility Management route is sent to UE
The reason for area, which updates, refuses (GMM RAU Reject) message, carrying (cause) value is GPRS Service Not allowed,
