The appearances of the phrase in various places in the specification are not necessarily all referring to the same embodiment, nor are separate or alternative embodiments mutually exclusive of other embodiments. It is explicitly and implicitly understood by one skilled in the art that the embodiments described herein can be combined with other embodiments.

Referring to fig. 1, fig. 1 is a schematic structural diagram of a Mobile terminal, and as shown in fig. 1, the Mobile terminal may include a smart Phone (e.g., an Android Phone, an iOS Phone, a Windows Phone, etc.), a tablet computer, a palm computer, a notebook computer, a Mobile Internet device (MID, Mobile Internet Devices), a wearable device, and the like. Of course, in practical applications, the user equipment is not limited to the above presentation form, and may also include: intelligent vehicle-mounted terminal, computer equipment, intelligent wrist-watch etc.. As shown in fig. 1, the terminal includes: the communication module 103 may be a Long Term Evolution (LTE) communication module or a 2G communication module in practical application, and in practical application, the LTE communication module and the 2G communication module may also be integrated together.

Referring to fig. 1A, fig. 1A may be a schematic diagram of a network architecture, as shown in fig. 1A, there are multiple MSCs on the core network side, and fig. 1A takes two MSCs as an example, and for convenience of distinction, the

MSCs

1 and 2 are taken as examples here. For the UE, after it establishes network connection through the eNB, if the GERAN1 is the first operator base station, at this time, the GERAN2 is the second operator base station.

Fig. 2 shows a flow of terminal communication, and a call flow is implemented under the network architecture shown in fig. 1A, in this case, the call flow is shown in fig. 2.

Step S200, UE sends MT call to eNB;

step S201, the eNB forwards the MT call to the MME,

step S202, the eNB sends CC _ SETUP to the UE to establish connection.

Step S203, the UE receives a Distributed Denial of Service (ddos) attack.

Step S204, the UE starts a cell reselection function and starts a frequency point search function to search frequency points (60, 75, 85, 95 and 100).

Step S205, the UE selects the GERAN2 corresponding to the frequency point 60 to initiate an access request.

Step S206, the UE receives the CC _ SETUP returned by the GERAN2 to establish connection.

As shown in the flowchart of fig. 2, the flowchart is a flowchart for accessing GERAN2, for this reason, it is necessary to determine whether the UE accesses GERAN2, so as to implement detection on the UE, and if the UE does not set the APN of GERAN2, the UE may not access GERAN2, so that the UE may not provide service for the user, and the experience of the user is affected.

Referring to fig. 3, fig. 3 provides a method for detecting a terminal access, which is performed by an emulator, the emulator being located in a detection system, the detection system including: the system comprises an LTE cell and a GSM cell, wherein the GSM cell comprises at least two base stations, a first base station belongs to a first operator, a second base station belongs to a second operator, and a simulator is connected with the two base stations. The method is shown in fig. 3, and comprises the following steps:

step S300, UE sends a first registration request to an emulator;

step S301, the simulator returns a first registration response to the UE to determine that the UE is successfully registered;

step S302, the simulator inquires UE to register a first APN according to a Public Land Mobile Network (PLMN) of a current network;

step S303, the emulator determines whether the UE sends a second APN, if the emulator determines that the UE does not report the second APN, the emulator compares whether the first APN is the same as the second APN or not if the terminal passes the detection, if the emulator determines that the UE sends the second APN;

step S304, if the first APN is the same as the second APN, the simulator determines that the APN of the UE passes the check.

Step S305, if the first APN is different from the second APN, the simulator determines that the APN fails to check, and sends a check failure message to the UE.

The technical scheme provided by the invention realizes the inspection of whether the APN of the UE is abnormal, so that the UE with the abnormal APN cannot leave a factory, the data access success rate of the UE leaving the factory is improved, and the experience degree of a user is improved.

The steps of the method provided in the embodiment shown in fig. 3 have different technical solutions in different combinations, for example, the combination of the above steps S301, S302, S303, S304, S305 and S306 may be a method for detecting terminal access on the emulator side provided in the first aspect.

Optionally, the method may further include:

the detection failure message includes: a first APN.

The entry check failure message may be a self-defined identifier, and certainly, a general identifier may also be used in practical application, and the specific embodiment of the present invention does not limit the specific representation form of the identifier, where the failed first APN is returned to the UE, so that the UE can adjust the content of the log record, and a debugging person can more accurately obtain the reason for the error of the second APN of the UE.

The message of the detection failure may be represented in various ways, for example, in an optional technical solution of the present invention, the message of the detection failure may be a NACK message, and in practical applications, the message of the detection failure may also be a NACK message carrying a continuous number, for example, 9 continuous 1 or 10 continuous zeros, etc. Of course, in practical applications, the detection failure message may also be a newly set message.

Optionally, the method further includes:

the UE logs when sending the first registration request to the emulator, the log including all operations of the UE between the first registration request to the verification failure message.

Optionally, all the operations and instructions described above may further include but are not limited to: sending a first registration request at the UE to all operations that receive the verification failure message, including but not limited to: one or any combination of received and sent messages, frequency point scanning times, frequency point scanning results, all APNs or execution commands.

Of course, all the operations described above may have other information, and the present invention does not limit all the information corresponding to all the operations described above.

Optionally, the method may further include:

and the simulator receives the log sent by the UE, extracts the content of the log, and performs data analysis on the content of the log to obtain a primary failure result.

The specific method for obtaining the preliminary failure result by performing data analysis on the log content may be as follows:

extracting the sending time t1 of the random access preamble sent by the UE when the UE establishes connection with the simulator, inquiring the random access response in the log, if the random access response is not inquired, inquiring whether the preamble value is zero, if the preamble value is not zero, determining that the preliminary failure result is simulator configuration error, if the random access response is inquired, determining the receiving time t2 of the random access response, if t2-t1 is larger than a time threshold, and determining that the preliminary failure result is processing delay error.

For the random access, the non-contention access and the contention access are distinguished, and different from the preamble number (preamble index) in the non-contention based random access, which is designated by the eNB, the preamble index of the contention based random access is randomly selected by the UE.

The UE first determines whether a preamble in group a or group B is selected. If there is preamble Group B, and msg3 of Group B is greater than msg3 of message Size Group A, and path loss (path loss) is less than P_CMAX,C(a set threshold), selecting group B; otherwise, group A is selected.

If msg3 was sent before and the access failed, the preamble used in the re-access attempt should belong to the same group as the corresponding preamble when msg3 was sent for the first time.

After the group is determined, the UE randomly selects a preamble from the group and sets the time-frequency resource index to 0. For non-contention based random access, the eNB avoids collision and assigns a time-frequency resource index by allocating a dedicated preamble index to the UE.

There are two ways for eNB to allocate preamble Index and PRACH Mask Index:

the mode A is set through the fields of an ra-Preamble Index and an ra-PRACH-Mask Index of RACH-Config Dedicated;

and the mode B is set through Preamble Index and PRACH Mask Index fields of the DCI format 1A in the PDCCH order triggered random access (downlink data arrival or positioning).

If the eNB assigns a value of 0, the actual preamble index is handed over to the UE to select the preamble in a contention-based random access manner (this is mainly the case when the eNB has no available non-contention preamble or the eNodeB has not reserved the preamble for the non-contention random access at all when configured).

Selecting PRACH resources for sending a preamble; based on the PRACH-Config Index, the PRACH Mask Index, and the timing constraint of the physical layer, the UE will first determine the next available subframe containing the PRACH. The PRACH-ConfigIndex specifies the PRACH resources available in the time domain. The PRACH Mask Index defines which PRACH within a system frame a certain UE may send a preamble on. In non-contention based random access, the eNB may directly specify the UE to send the preamble on a certain PRACH through the mask, thereby ensuring that no collision occurs with other UEs.

Taking ra-PRACH-Mask Index 3 as an example, the corresponding PRACH Resource Index 2, that is, preamble should be sent in the third PRACH Resource in the system frame. The PRACH Resource Index is a number of PRACH resources in a system frame, and only Packet Random Access Channel (PRACH) resources exist on subframes 0,2,4,6, and 8, and the PRACH Resource Index 2 corresponds to the PARCH Resource on subframe 4; if the Uplink (UL)/Downlink (DL) configuration (configuration) is 1, the PRACH Resource Index 2 corresponds to the PARCH Resource on the quadruplet (0,0,1, 0). The PRACH Mask Index may be 0, which indicates that the eNB only allocates preamble to the UE, but the PRACH resource needs to be selected by the UE itself. If the UE receives one RAR MAC PDU at subframe n but none of the corresponding TBs correspond to the preamble it sends, the UE should be ready for transmission no later than subframe n +5And retransmitting the preamble within the time interval. If the UE does not receive one RAR MAC PDU at subframe n, which is the last subframe of the RAR window, the UE should be ready to retransmit the preamble no later than subframe n + 4. If the random access procedure is triggered by PDCCH order in subframe n, the UE will be in subframe n + k₂Starting with the first subframe with available PRACH, where k₂≧ 6. Up to this point, the subframe where the PRACH resides has been selected, and then we start to select the location on the frequency domain. In TDD mode and PRACH Mask Index 0: if the eNodeB designates the ra-Preamble Index and the value of the ra-Preamble Index is not 0, randomly selecting a PRACH on the subframe determined previously; otherwise, one PRACH is randomly selected in the previously determined subframe and two subsequent subframes (3 subframes in total). And if the FDD mode or the PRACH Mask Index is not 0, selecting one PRACH according to the PRACH Mask Index.

Determining a corresponding RA-RNTI

The time-frequency position of the preamble determines the value of the RA-RNTI, and after the UE sends the preamble, the UE monitors the corresponding PDCCH according to the RA-RNTI value in the RAR time window. The TARGET RECEIVED POWER PREAMBLE _ RECEIVED _ TARGET _ POWER is determined.

After the UE sends the preamble, it monitors the PDCCH in an RAR time window (RA Response window) to receive RAR corresponding to the RA-RNTI. If the RAR replied by the eNodeB is not received within the RAR time window, the random access procedure is considered to fail. The RAR time Window starts from the subframe where the preamble is sent (if the preamble spans multiple subframes in the time domain, the last subframe is used to calculate) +3 subframes, and ra-Response Window Size subframes are continued.

the emulator queries all APNs in the log, determines whether all APNs have the first APN, if so, determines that the preliminary failure result may be a UE registration error, and if not, determines that the preliminary failure result may be a UE APN configuration error.

and extracting the number of the packet random access signal resource identifier in the content of the log, determining whether the number of the packet random access signal resource identifier is legal or not, and if the number of the random access signal resource identifier is illegal, determining that the primary failure result is a packet service error.

For the number of the packet random access signal Resource identifier (PRACH Resource Index), one of the numbers is on an even subframe, and if the number is on an odd subframe, the number error may be a random access error or a timing error, which may cause the number error to occur, and thus may affect the access of the data service.
