in this embodiment, the terminal may be in an unregistered state after receiving the attach reject message carrying the cause value, and at this time, a User Interface (UI) of the terminal may be displayed as an "unregistered state". After the attachment rejection message is sent to the terminal, the terminal may count the time at a set time interval T3245, and after the count is finished, detect whether the terminal sends the second access request message to the second GSM cell.

6. The method of claim 1, wherein the determining whether the terminal successfully accesses the second GSM cell based on the detection result of the user plane data comprises:
judging whether the rate of user plane data between the terminal and the second GSM cell is greater than or equal to a preset threshold value or not;
if the rate of the user plane data between the terminal and the second GSM cell is larger than or equal to a preset threshold value, determining that the terminal is successfully accessed into the second GSM cell;
and if the rate of the user plane data between the terminal and the second GSM cell is less than a preset threshold value, determining that the terminal fails to access the second GSM cell.
7. The method according to any one of claims 1 to 6, further comprising:
establishing a simulation network environment, wherein the simulation network environment at least comprises the following network structures: a long term evolution, LTE, network, a GSM network; the system message block SIB7 of the LTE network is configured with GSM neighbor cell information, and the system message SI of the GSM network is configured with LTE neighbor cell information; the GSM network is configured with two GSM cells with the same PLMNID;
correspondingly, the first GSM cell and the second GSM cell which interact with the terminal are GSM networks in the simulated network environment.
8. The device for detecting the access result is applied to a process that a terminal performs data network access by adopting a preset optimization scheme, wherein an abnormal scene aimed at by the optimization scheme is as follows: the terminal enters a user identity identification module state due to the failure of initial registration, so that the terminal cannot access a data network; the device comprises: a receiving section, a transmitting section, a detecting section, and a determining section; wherein the content of the first and second substances,
the receiving part is configured to receive a first access request message sent by the terminal to a first global system for mobile communications (GSM) cell;
the sending part is configured to send an attach reject message to the terminal for the first access request message;
the detection part is configured to detect that the access state of the terminal is an unregistered state, and after a set time interval, detect whether the receiving part receives a second access request message sent by the terminal to a second GSM cell; wherein the second GSM cell has the same public land mobile network identity (PLMN ID) as the first GSM cell;
the sending part is further configured to send an attach success message to the terminal after the receiving part receives the second access request message;
the detection part is also configured to detect user plane data between the terminal and the second GSM cell;
the determining part is configured to determine whether the terminal successfully accesses the second GSM cell based on a detection result of the user plane data.
9. The device for detecting the access result is applied to a process that a terminal performs data network access by adopting a preset optimization scheme, wherein an abnormal scene aimed at by the optimization scheme is as follows: the terminal enters a user identity identification module state due to the failure of initial registration, so that the terminal cannot access a data network; the device comprises: a processor and a memory for storing a computer program capable of running on the processor,
wherein the processor is adapted to perform the steps of the method of any one of claims 1 to 7 when running the computer program.
10. A computer storage medium, on which a computer program is stored which, when being executed by a processor, carries out the steps of the method of any one of claims 1 to 7.
