And aiming at the abnormal access scene, a preset optimization scheme is adopted at the terminal side to execute the access process of the data network, whether the terminal is successfully accessed to the data network is detected, and finally the effectiveness and the reasonability of the optimization scheme adopted by the terminal are determined.
In the embodiment of the present invention, a network environment (referred to as a simulation network environment) may be constructed by a simulation platform, where the simulation network environment at least includes the following network structures: an LTE cell, a TDSCDMA cell and a GSM cell; wherein, a System Information Block (SIB) 7 of the LTE cell is configured with GSM neighbor cell Information, and an SIB5 of the LTE cell is configured with TDSCDMA neighbor cell Information; LTE (Long term evolution) neighbor cell Information is configured in a System message (SI) of the GSM cell; and a Location Area Code (LAC) Code value of the TDSCDMA cell is the same as a Tracking Area Code (TAC) Code value of the LTE cell. FIG. 1 is a schematic diagram of a SIB7 displayed via a computer display screen; FIG. 2 is a schematic diagram of a SIB5 displayed via a computer display screen; fig. 3 is a schematic diagram showing SI of a GSM cell through a computer display screen.

Here, since the network is implemented by using a simulation platform, the network can stably reproduce an abnormal access scenario with the terminal, thereby verifying feasibility and stability of the optimization scheme.
Based on the above simulated network environment, the following describes the technical solution of the embodiment of the present invention in detail.
Example one
Fig. 4 is a schematic flowchart of a method for detecting an access result according to an embodiment of the present invention, where the flowchart is applied to a process in which a terminal performs data network access by using a preset optimization scheme, as shown in fig. 4, the method for detecting an access result may include the following steps:
s401: receiving an attach request AttachRequest message sent by the terminal to an LTE cell;
in this embodiment, the terminal may be triggered to perform a registration procedure with the LTE cell, and then in the registration procedure, after the terminal completes an RRC connection establishment procedure with the LTE cell, the terminal may send an attach request message to the LTE cell through a Non-access stratum (NAS) message. Specifically, the RRC connection establishment procedure may include: the LTE cell receives an RRC Connection Request message (RRC Connection Request) for the LTE cell sent by a terminal, and then the LTE cell sends an RRC Connection Setup message (RRC Connection Setup) to the terminal.
S402: sending an attach reject message to the terminal for the attach request message;
in this embodiment, after receiving the attach request message, the LTE cell (specifically, the LTE cell in the location-emulated network environment) may implement issuing an attach reject message to the terminal through the emulation platform.
Therefore, in this embodiment, the method may further include: and encapsulating an attachment rejection message, wherein the attachment rejection message carries the reason value of the attachment failure, and the reason value of the attachment failure is used for representing the reason of the attachment failure.
Taking the Attach Reject message as "Attach Reject" as an example, the encapsulation reason cause value in "Attach Reject" is 15, and the specific cause content is "No successful Cells in tracking area", where "No successful Cells in tracking area" represents that the cause of the Attach failure is that there is No Suitable cell in the tracking area. FIG. 5 is a schematic diagram of the cause value displayed by the computer display screen.
S403: after detecting an access request message sent by the terminal to a TDSCDMA cell, sending a correct routing area update receiving RAU Accept message to the terminal;
in this embodiment, the Access Request message may specifically be an RRC Connection Request message sent by the terminal for the TDSCDMA cell, where the TDSCDMA cell (specifically, a TDSCDMA cell in an emulated Network environment) performs a Routing Area Update (RAU) procedure after receiving the RRC Connection Request message, and issues a correct RAU Accept message to the terminal, where it needs to be noted that, in the RAU Accept message, a coding value of a Routing Area Code (RAC) is the same as a TAC coding value of the LTE cell, and in the RAU Accept message, a Network Service Access Point Identifier (NSAPI) value is used to mark a Packet Data Protocol (PDP) as an inactive state.
S404: after receiving a packet data protocol context activation (PDPContextAction) request sent by the terminal based on the TDSCDMA cell, sending a Radio Access Bearer setup signaling (RAB setup) to the terminal;
in this embodiment, after receiving the RAU Accept message, the terminal may send a pdpcontextaction request to the TDSCDMA cell to activate the PDP because the NSAPI value in the RAU Accept message marks that the PDP is in an inactive state, and the TDSCDMA cell issues an rabsetup signaling to establish a Packet Switched (PS) radio access bearer after receiving the pdpcontextaction request, thereby continuing the RAU procedure.
S405: and after detecting that the terminal successfully establishes RAB of the PS domain, detecting user plane data between the terminal and the TDSCDMA cell, and determining whether the terminal successfully accesses the TDSCDMA cell based on a detection result of the user plane data.
In the embodiment of the present invention, it is preferable that whether the terminal successfully accesses to the TDSCDMA cell may be determined by verifying whether user plane data between the terminal and the TDSCDMA cell is clear.
Specifically, the determining whether the terminal successfully accesses the TDSCDMA cell based on the detection result of the user plane data includes:
judging whether the rate of user plane data between the terminal and the TDSCDMA cell is larger than or equal to a preset threshold value;
if the speed of user plane data between the terminal and the TDSCDMA cell is larger than or equal to a preset threshold value, determining that the terminal is successfully accessed into the TDSCDMA cell;
and if the rate of the user plane data between the terminal and the TDSCDMA cell is less than a preset threshold value, determining that the terminal fails to access the TDSCDMA cell.
It should be noted that, in the technical solution of the embodiment of the present invention, the feasibility and the stability of the optimization scheme are verified according to the successful access of the terminal to the TDSCDMA cell, so that in the process of accessing the terminal to the TDSCDMA cell, if a failure occurs, it can be determined that the access of the terminal to the TDSCDMA cell fails, thereby verifying that the preset optimization scheme fails.
Based on this, the embodiment of the present invention may preferably also perform verification through whether the terminal sends the access request message to the TDSCDMA cell, and in particular, when it is detected that the terminal fails to send the access request message to the TDSCDMA cell, it is determined that the terminal fails to access the TDSCDMA cell. In detail, the simulation network environment may time according to a set time interval after issuing the attach rejection message; before the timing is finished, receiving an access request message sent by the terminal to the TDSCDMA cell, and continuing to execute S404 and S405; and after the timing is finished, if the access request message sent to the TDSCDMA cell by the terminal is not received, determining that the access request message is failed to be sent, thereby determining that the terminal fails to be accessed to the TDSCDMA cell.
In addition, the embodiment of the present invention may preferably further perform verification by whether the terminal sends a packet data protocol context activation (PDPContextActivation) request based on the TDSCDMA cell, and in particular, when it is detected that the terminal fails to send the PDPContextActivation request to the TDSCDMA cell, it is determined that the terminal fails to access the TDSCDMA cell. In detail, the emulated network environment may time according to a set time interval after issuing the RAU Accept message; before the timing is finished, a PDPContextActivation request sent by the terminal to the TDSCDMA cell is received, and S405 is continuously executed; and after the timing is finished, if the PDPContextAction request sent by the terminal to the TDSCDMA cell is not received, determining that the access request message is failed to be sent, thereby determining that the terminal fails to access the TDSCDMA cell.
