Here, since the network is implemented by an emulation platform, this kind of network can stably reproduce the abnormal access scenario with the terminal, thereby verifying the feasibility and stability of the optimization scheme.

Based on the above-mentioned simulated network environment, the technical solutions of the embodiments of the present invention are described in detail below.

Example 1

An embodiment of the present invention provides a method for detecting a network access result, and FIG. 3 is a schematic flowchart of a method for detecting a network access result according to an embodiment of the present invention; as shown in FIG. 3 , the method includes:

Step 101: Receive the first attach request message of the terminal; the first attach request message is selected after the terminal registers in the LTE network and switches to the OOS state, and the signal strength of the GSM cell as a neighboring cell is improved. Sent after the GSM cell described above.

Step 102: Send a first attach rejection message to the terminal representing an abnormality of the General Packet Radio Service GPRS network.

Step 103: Repeatedly detecting whether the second attach request of the terminal is obtained before the timing of the first timer arrives, and sending a second attach rejection message to the terminal; the first timer is sending a second attach request to the terminal. Started when the first attach rejection message/second attach rejection message occurs.

Step 104: Determine whether the terminal successfully accesses the GSM cell based on the detection result.

In the embodiment of the present invention, based on the constructed simulated network environment, the terminal registers with the LTE network, and establishes the LTE-based bearer. The LTE-based bearer may be a default Evolved Packet System (EPS, Evolved Packet System) bearer (Default EPS bearer), which activates user plane data of the LTE network.

Here, before the terminal registers to the LTE network, the network access process of the LTE network needs to be performed. The network access process may include: detection system message broadcast, cell selection, initial access process and RRC connection process; wherein, the simulation platform simulates the network The system message broadcast is sent on the side, and the terminal performs cell selection based on the system message broadcast. In this embodiment, the terminal selects the LTE network; the terminal completes the initial access procedure with the LTE network, and the terminal establishes an RRC connection with the LTE network.

In the embodiment of the present invention, based on the decrease of the signal strength of the LTE serving cell where the terminal is located, the terminal is switched to the OOS state; When the access threshold is reached, the terminal performs cell reselection and selects a GSM cell for access.

In practical applications, as an implementation manner, before receiving the first attach request message of the terminal, the method further includes: receiving a first measurement report of the terminal, where the first measurement report indicates the quality of the serving cell is lower than a certain threshold and the quality of the neighboring cells of the inter-system is higher than a certain threshold; as an example, the first measurement report may be a B2 measurement report (B2MeasurementReport). Receiving the first measurement report or sending the first measurement report by the terminal indicates that the terminal is to perform cell reselection to select a neighbor cell with good signal quality. The LTE network simulated by the simulation platform receives the first measurement report of the terminal. After the terminal performs cell reselection to select a GSM cell with better signal quality, the GSM network simulated by the simulation platform receives the terminal's first attach request message.

In practical application, after receiving the first attach request message sent by the terminal, the network device (such as a GSM base station) simulated by the simulation platform forwards the first attach request message to the MME, and the network device (such as the MME and the HSS) sends the first attach request message to the MME. The terminal performs attachment-related processing in the GSM network, including authentication, location management, etc., to complete registration in the GSM network.

In the embodiment of the present invention, a first attach rejection message representing an abnormality of the GPRS network is sent to the terminal. As an implementation manner, before the sending a first attach rejection message representing an abnormality of the GPRS network to the terminal, the method further includes: encapsulating a first attach rejection message, where the first attach rejection message carries an attach rejection message. The reason value, the reason value of the attach rejection is used to represent the reason of the attach rejection; wherein, the reason value of the attach rejection in the attach rejection message is used to represent the abnormality of the GPRS network.

In a practical application, taking the GMM cause value encapsulated in the attach rejection message as "GPRS service not allowed (7)" as an example, here, "GPRS service not allowed" indicates that the GPRS network is abnormal. FIG. 4 is a schematic diagram of an abnormal GMM cause value carried in a refuse attachment message displayed on a computer display screen.

In this embodiment of the present invention, based on sending the first attach rejection message to the terminal, it is detected whether repeated detection obtains the second attach request of the terminal before the timing of the first timer arrives, and the second attach request is sent to the terminal. an attach rejection message; the first timer is started when a first attach rejection message/second attach rejection message is sent to the terminal.

Here, verifying whether the optimization scheme is successful may include the following implementations:

In this embodiment, when sending the first attach rejection message to the terminal, a first timer may be started, and the second attach request from the terminal is received before the timing of the first timer arrives, and the first attach request is sent to the terminal. 2. Refuse to attach message; further start the first timer when sending the second reject to attach message, receive the second attach request of the terminal before the timing of the first timer expires, and send the second to reject the attach message to the terminal , repeating the above operations, repeatedly detecting that the second attach request of the terminal is received before the timing time of the first timer arrives, until it is detected that the number of repetitions reaches a preset threshold, it can be determined that the optimization scheme is successful. Then, determining whether the terminal successfully accesses the GSM cell based on the detection result includes: receiving a second attach request of the terminal after the number of repetitions reaches a preset threshold, and pairing the terminal based on the second attach request. The terminal performs authentication, and obtains a successful authentication result; allocates downlink resources to the terminal to complete the terminal access process; sends an attach success message to the terminal; detects the camp on the GSM cell where the terminal resides. The dwell time is determined. When the dwell time reaches a preset time, it is determined that the terminal successfully accesses the GSM cell.

Wherein, the attach refusal cause value carried in the second attach refusal message may be the same as the attach refusal cause value carried in the first attach refusal message.

As a second implementation manner, the determining whether the terminal successfully accesses the GSM cell based on the detection result includes: when the detection result is that the terminal is not obtained before the timing of the first timer arrives When the second attach request is sent, it is determined that the terminal fails to access the GSM cell.

In this embodiment, a first timer can be started when the first attach rejection message is sent to the terminal, and an optimization scheme can be determined if the second attach request of the terminal is not received before the time of the first timer arrives If it fails, it is determined that the terminal has not successfully accessed the GSM cell.

As a third implementation manner, the determining whether the terminal successfully accesses the GSM cell based on the detection result includes: when the detection result is that the terminal's information is obtained before the timing of the first timer arrives When the number of repetitions of the second attach request and sending the second attach rejection message to the terminal does not reach a preset threshold, it is determined that the terminal has not successfully accessed the neighboring cell.

In this embodiment, when sending the first attach rejection message to the terminal, a first timer may be started, and the second attach request from the terminal is received before the timing of the first timer arrives, and the first attach request is sent to the terminal. 2. Refuse to attach message; further start the first timer when sending the second reject to attach message, receive the second attach request of the terminal before the timing of the first timer expires, and send the second to reject the attach message to the terminal , repeat the above operation, repeatedly detect that the second attach request of the terminal is received before the timing time of the first timer arrives, and detect that the number of repetitions does not reach the preset threshold, that is, before the number of repetitions reaches the preset threshold, If the second attach request of the terminal is not received before the timing time of the first timer arrives, it may be determined that the optimization solution fails.

In this embodiment of the present invention, the preset threshold corresponding to the number of repetitions is a preset maximum network capacity, and the preset threshold may be obtained and set in advance through an experiment or a test during the optimization process.

Based on this, in an embodiment, the method may further include: establishing a simulated network environment, where the simulated network environment includes at least the following network structures: an LTE network, a TDSCDMA network, and a GSM network, wherein, in SIB5 of the LTE network TDSCDMA neighboring cell information is configured, SIB7 of the LTE network is configured with GSM neighboring cell information, and SI of the GSM network is configured with LTE neighboring cell information;

Correspondingly, the network interacting with the terminal is the network in the simulated network environment.

By adopting the solution of the embodiment of the present invention, the terminal adopts the preset optimization solution to perform the network access process, and when the terminal is in the OOS state due to the loss of the original RAT signal, it reselects to the scenario of abnormal access to the GPRS data network. In the scenario, the configuration error on the network side causes the terminal's attach request to be rejected many times, in order to stably reproduce the occurrence of a small probability in the network due to OOS reselection to the abnormal GPRS data access, check whether the number of times the terminal's attach request is repeatedly received. The optimized maximum network capacity is reached, thereby verifying the effectiveness and rationality of the optimization scheme, providing a basis for further improving the optimization scheme, and improving the user's online experience.

In addition, the network interacting with the terminal is a network in a simulated network environment. The simulation method does not require staff to go to the site, and other factors that affect the detection can be removed. In this way, the personnel cost can be greatly reduced, and at the same time, it can be eliminated. Influences of other factors on the detection results in the scenarios described in the embodiments of the present invention.

The present invention will be described in further detail below in conjunction with an application example.

In this application embodiment, a network environment is constructed through a simulation platform, and the construction of the network environment may refer to the foregoing construction method, which is not repeated in this embodiment. The method for detecting a network access result in this application embodiment includes the following steps:

Step 201: Trigger the UE to power on and register on the LTE cell, establish a Default EPS bearer, and activate user plane data.

Step 202: Decrease the signal strength of the serving cell (LTE cell) of the UE for a period of time to trigger the UE to enter the OOS state.

Step 203: Increase the signal strength of the UE's neighbor cell (GSM cell) higher than the access threshold TH1, and the UE starts to send an Attach Request (ie, Attach Request) message to the GSM cell, and the Attach Request message carries the access reason value. In this embodiment, the access reason value may be that the quality of the current serving cell is lower than the access threshold, and the signal strength of the neighboring cell is higher than the access threshold.

Step 204: The simulation system starts to detect at the GSM layer whether the UE's Attach Request (ie Attach Request) message is received, and after detecting that the UE's Attach Request (ie, Attach Request) message is received, step 205 is performed.

Step 205: The simulation system simulates the network equipment of the GSM network to start the subsequent process of cell reselection, and execute the authentication process.

Step 206: The simulation system simulates an abnormal situation, rejects the attach request of the UE, and sends a refusal to attach (ie, Attach Reject) message to the UE, and the attach refusal message carries a cause value. In this embodiment, the cause value is carried. It can be "GPRS Services not allowed", as shown in FIG. 4 for details.

Step 207: The simulation system starts to detect at the GSM layer whether it can re-receive the attachment request (ie Attach Request) of the UE before the timing of the specified timer (timer) arrives; if the attachment of the UE is received before the timing of the timer arrives Request (that is, Attach Request), the simulation system simulates the abnormal situation again, and resends the attach rejection (that is, Attach Reject) message, and the carried reason value can be the same. Repeat the number of abnormal simulations to N-1 times (where N is the maximum network capacity after optimization), until after the N-1st simulation abnormal scenario sends the rejection message, it can still be received before the timer's timing time arrives. The attachment request (ie Attach Request) of the UE indicates that the optimization scheme is successful.

Step 208: If the UE's Attach Request (ie, Attach Request) is not received before the specified timer (timer) arrives, it is determined that the optimization solution fails.

Step 209: If the number of repeated abnormal simulations does not reach N-1 times, it is determined that the optimization scheme fails.
