Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings and specific embodiments.

In the technical scheme of the embodiment of the invention, an abnormal access scene is simulated, namely: and reselecting to a scene of abnormal access of the GPRS data network under the condition that the terminal is in an OOS state due to the loss of the original RAT signal.

Aiming at the abnormal access scene, the network side configuration error causes the repeated refusal of the attachment request of the terminal, so as to stably reappear the condition that the small probability of the occurrence of the network is abnormal due to the fact that the OOS reselects to the GPRS data access, and detect whether the times of repeatedly receiving the attachment request of the terminal reaches the optimized maximum network accommodating times, thereby verifying the effectiveness and the rationality of the optimization scheme.

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: the system comprises an LTE network, a TDSCDMA network and a GSM network, wherein TDSCDMA neighboring cell information is configured in SIB5 of the LTE network, GSM neighboring cell information is configured in SIB7 of the LTE network, and LTE neighboring cell information is configured in SI of the GSM network. FIG. 1 is a schematic illustration of the display of SIB5 through a computer display screen, and FIG. 2 is a schematic illustration of the display of SIB7 through a computer display screen.

And then, executing a network access process based on the constructed network environment, wherein main objects involved in the LTE network access process comprise a terminal and a network, wherein the terminal can be realized by adopting a mobile phone but not limited to be realized by adopting the mobile phone, and the network can be realized by adopting a simulation platform. 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. 3 is a schematic flow chart 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: receiving a first attach request message of the terminal; the first attach request message is sent after the terminal is registered in an LTE network, is switched to an OOS state, and selects a GSM cell as a neighbor cell after the signal strength of the GSM cell is improved.

Step 102: and sending a first attach rejection message representing the abnormity of the GPRS network to the terminal.

Step 103: repeatedly detecting whether a second attachment request of the terminal is obtained before the timing time of the first timer is reached, and sending a second attachment refusing message to the terminal; the first timer is started when the first/second attach reject message is sent to the terminal.

Step 104: and determining whether the terminal is successfully accessed to the GSM cell based on the detection result.

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

Here, before the terminal registers to the LTE network, a network access procedure of the LTE network needs to be performed, where the network access procedure may include: detecting system message broadcasting, cell selection, an initial access process and an RRC connection process; the simulation platform simulates a network side to send system message broadcast, and the terminal performs cell selection based on the system message broadcast, wherein in the embodiment, the terminal selects an LTE network; and the terminal and the LTE network complete an initial access process, and the terminal and the LTE network establish RRC connection.

In the embodiment of the invention, the terminal is switched to the OOS state based on the reduction of the signal intensity of the LTE service cell where the terminal is located; on the other hand, if the signal strength of the GSM cell, which is the neighboring cell, is increased to the access threshold, the terminal reselects the cell and selects the 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, wherein the first measurement report indicates that the quality of a service cell is lower than a certain threshold and the quality of an inter-system adjacent cell is higher than a certain threshold; as an example, the first measurement report may be a B2measurement report (B2 MeasurementReport). And receiving the first measurement report or sending the first measurement report by the terminal to indicate that the terminal is to perform cell reselection to select the adjacent cell with good signal quality. And the LTE network simulated by the simulation platform receives a first measurement report of the terminal. After the terminal reselects the cell to select the GSM cell with better signal quality, the GSM network simulated by the simulation platform receives a first attachment request message of the terminal.

In practical application, after receiving a first attach request message sent by a terminal, a network device (e.g., a GSM base station) simulated by a simulation platform forwards the first attach request message to an MME, and the network device (e.g., the MME and an HSS) performs attach-related processing on the terminal in a GSM network, including authentication, location management, and the like, so as to complete registration in the GSM network.

In the embodiment of the invention, a first attach rejection message representing the abnormal GPRS network is sent to the terminal. As an embodiment, before sending the first attach reject message indicating the GPRS network anomaly to the terminal, the method further includes: encapsulating a first attach rejection message, wherein the first attach rejection message carries an attach rejection cause value, and the attach rejection cause value is used for representing an attach rejection cause; wherein the cause value of the attach reject in the attach reject message is used for characterizing a GPRS network anomaly.

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

In the embodiment of the invention, based on the first attachment rejection message sent to the terminal, whether a second attachment request of the terminal is obtained before the timing time of a first timer is reached or not is detected repeatedly, and a second attachment rejection message is sent to the terminal; the first timer is started when the first/second attach reject message is sent to the terminal.

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

as a first implementation manner, the determining whether the terminal successfully accesses the GSM cell based on the detection result includes: and when the detection result is that a second attachment request of the terminal is obtained before the timing time of the first timer reaches and the repetition times of sending a second attachment rejection message to the terminal reaches a preset threshold value, determining that the terminal is successfully accessed into the GSM cell.

In this embodiment, when sending the first attach rejection message to the terminal, the first timer may be started, and the second attach rejection message may be sent to the terminal after receiving the second attach request from the terminal before the timing time of the first timer is reached; and further starting the first timer when sending a second attachment rejection message, receiving a second attachment request of the terminal before the timing time of the first timer reaches, sending the second attachment rejection message to the terminal, repeating the operations, and repeatedly detecting that the second attachment request of the terminal is received before the timing time of the first timer reaches until the repetition times reaches a preset threshold value, so that the success of the optimization scheme can be judged. The determining whether the terminal successfully accesses the GSM cell based on the detection result includes: receiving a second attachment request of the terminal after the repetition times reach a preset threshold value, authenticating the terminal based on the second attachment request, and obtaining an authentication success result; allocating downlink resources to the terminal to complete the terminal access process; sending an attachment success message to the terminal; and detecting the residence time of the terminal residing in the GSM cell, and determining that the terminal successfully accesses the GSM cell when the residence time reaches the preset time.

Wherein, the cause value of the attach rejection carried by the second attach rejection message and the cause value of the attach rejection carried by the first attach rejection message may be the same.

As a second implementation manner, the determining whether the terminal successfully accesses the GSM cell based on the detection result includes: and when the detection result is that the second attachment request of the terminal is not obtained before the timing time of the first timer is reached, determining that the terminal does not successfully access the GSM cell.

In this embodiment, when the first attach reject message is sent to the terminal, the first timer may be started, and if the second attach request of the terminal is not received before the timing time of the first timer reaches, it may be determined that the optimization scheme fails, that is, it is determined that the terminal does not successfully access the GSM cell.

As a third implementation manner, the determining whether the terminal successfully accesses the GSM cell based on the detection result includes: and when the detection result is that the repetition times of obtaining a second attachment request of the terminal and sending a second attachment rejection message to the terminal do not reach a preset threshold value before the timing time of the first timer reaches, determining that the terminal does not successfully access the adjacent cell.

In this embodiment, when sending the first attach rejection message to the terminal, the first timer may be started, and the second attach rejection message may be sent to the terminal after receiving the second attach request from the terminal before the timing time of the first timer is reached; and further starting the first timer when sending a second attachment rejection message, receiving a second attachment request of the terminal before the timing time of the first timer reaches, sending the second attachment rejection message to the terminal, repeating the above operations, repeatedly detecting that the second attachment request of the terminal is received before the timing time of the first timer reaches, and judging that the optimization scheme fails when detecting that the repetition times does not reach a preset threshold value, namely before the repetition times reaches the preset threshold value, and not receiving the second attachment request of the terminal before the timing time of the first timer reaches.

In the embodiment of the invention, the preset threshold corresponding to the repetition times is the preset maximum network accommodating times, and the preset threshold can be obtained and set in advance in an optimization process in an experimental mode or a test mode.

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

By adopting the scheme of the embodiment of the invention, the terminal executes the network access process by adopting the preset optimization scheme, and reselects to the scene of abnormal access of the GPRS data network when the terminal is in the OOS state due to the loss of the original RAT signal, and under the abnormal scene, the network side configuration error causes the repeated refusal of the attachment request of the terminal, so as to stably reproduce the situation that the small probability of the network appears because the OOS reselects to the abnormal GPRS data access, and detect whether the times of repeatedly receiving the attachment request of the terminal reaches the optimized maximum network accommodating times, thereby verifying the effectiveness and rationality of the optimization scheme, providing a basis for further perfecting the optimization scheme, and improving the internet experience of users.

In addition, the network interacting with the terminal is a network in a simulation network environment, a simulation mode is adopted, workers do not need to go to the site, and other factors influencing detection can be removed, so that the personnel cost can be greatly reduced, and meanwhile, the influence of other factors on the detection result under the scene described by the embodiment of the invention can be eliminated.

The invention is described in more detail below with reference to an application example.

In this embodiment of the application, a network environment is constructed through the simulation platform, and the construction of the network environment may refer to the foregoing construction method, which is not described in detail in this embodiment.

In this embodiment, the access cause 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 whether an Attach Request (i.e., Attach Request) message of the UE is received at the GSM layer, and executes step 205 after detecting that the Attach Request (i.e., Attach Request) message of the UE is received.

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 an Attach Reject (i.e., Attach Reject) message to the UE, where the Attach Reject message carries a cause (cause) value, and in this embodiment, the cause (cause) value may be "GPRS Services not allowed," which may be specifically shown in fig. 4.

Step 207: the simulation system starts to detect whether the attachment Request (i.e. Attach Request) of the UE can be received again before the timing time of a specified timer (timer) arrives at the GSM layer; if an Attach Request (i.e., Attach Request) of the UE is received before the timing time of the timer arrives, the simulation system simulates the abnormal situation again, and resends an Attach Reject (i.e., Attach Request) message, which may carry the same cause value. Repeating the abnormal simulation times to N-1 times (wherein N is the optimized maximum network accommodation times), until after the attachment rejection message is sent in the N-1 th simulated abnormal scene, still receiving the attachment Request (namely the Attach Request) of the UE before the timing time of the timer is reached, and then indicating that the optimization scheme is successful.

Step 208: if the Attach Request (i.e., Attach Request) of the UE is not received before the timing time of the designated timer (timer) is reached, it is determined that the optimization scheme fails.

Step 209: and if the repeated abnormal simulation times do not reach N-1 times, judging that the optimization scheme fails.
