Description

Detection method and device, storage medium

Technical Field

The present invention relates to network access technologies in the field of mobile communications, and in particular, to a detection method, a detection device, and a storage medium.

Background

With the improvement of the demand of the user for the data service, higher requirements are put forward on the coverage area and the quality of a Long Term Evolution (LTE) network. Meanwhile, a Global System for Mobile Communication (GSM)/Time Division Synchronous Code Division Multiple Access (TDSCDMA) network is still used, and therefore, it is a better transition scheme for the LTE network and the TDSCDMA/GSM network to perform co-site deployment based on the original network System.

For LTE/TDSCDMA/GSM networks, a co-sited deployment scheme may share part of network elements, resulting in a higher coupling degree of a multi-Radio Access Technology (RAT) system. In the optimization process of each RAT system, unpredictable problems are often caused to shared network elements of other RAT systems, which results in failure of the optimization process or long optimization time.

In order to solve the problem caused by the incompatibility of network deployment, various optimization means are adopted by each terminal (UE) manufacturer to improve the User experience of the network. However, since the occurrence of various abnormal situations may probabilistically cause the UE to access the network, it is necessary to effectively detect the network access result in an abnormal situation.

Detailed Description

So that the manner in which the features and aspects of the embodiments of the present invention can be understood in detail, a more particular description of the embodiments of the invention, briefly summarized above, may be had by reference to the embodiments, some of which are illustrated in the appended drawings.

In the technical scheme of the embodiment of the invention, under the condition of coexistence of multiple RAT networks in a laboratory environment, after the original RAT signal is lost and enters an OOS state, the terminal selects and rapidly searches an optimization scheme of the network according to the resident record, and the feasibility and the stability of the optimization scheme are verified. Specifically, after the original LTE signal loss enters the OOS state, the terminal can quickly search for a network according to the resident record, such as the record of the resident TDSCDMA cell, and select the optimization scheme of the TDSCDMA cell, and verify the feasibility and stability of the optimization scheme.

In the embodiment of the invention, a network environment can be constructed through the simulation platform, for example, a simulation network environment is constructed, so that the method of the embodiment of the invention is realized through the simulation network environment, the simulation network environment is utilized to reproduce the scene that the terminal can quickly reselect to the network according to the resident record after the LTE system with small probability in the network enters the OOS state, and the feasibility and the stability of the scheme that the terminal quickly reselects to the network according to the resident record after the LTE system enters the OOS state are verified.

For example, the simulation network environment includes at least the following network structures: the system comprises a time division duplex TDD-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. Here, FIG. 1 is a schematic diagram of the SIB5 being displayed through a computer display screen, and FIG. 2 is a schematic diagram of the SIB7 being displayed through a computer display screen.

Furthermore, the method according to the embodiment of the present invention is implemented based on the above-constructed simulation network environment, where the main objects related to the method according to the embodiment include user equipment and a network, where the user equipment may be implemented by, but is not limited to, a mobile phone, and the network is implemented by using the simulation network environment constructed by the simulation platform.

Further, on the basis of the above-mentioned simulated network environment, a detection method according to an embodiment of the present invention is further described in detail, and specifically, fig. 3 is a schematic diagram of an implementation flow of the detection method according to the embodiment of the present invention, where the method is applied to a detection device, and in practical application, a simulation platform that is configured with the above-mentioned simulated network environment may integrate the detection device, that is, the method according to the embodiment of the present invention may be implemented by a simulation platform that is configured with the above-mentioned simulated network environment, and the method is applied to a process in which a terminal performs network access by using a preset optimization scheme, as shown in fig. 3, the method includes:

step 301: receiving an attachment request message for attaching to a Long Term Evolution (LTE) cell sent by a terminal, and completing an attachment process of the terminal on the LTE cell, wherein the terminal is in an out-of-service (OOS) state entered after a Time Division Synchronous Code Division Multiple Access (TDSCDMA) cell is deactivated, and the TDSCDMA cell is a cell where the terminal resides after being reselected from a global system for mobile communications (GSM) cell;

that is to say, in this embodiment, after the TDSCDMA cell terminal is deactivated to enter the OOS state, the terminal initiates an attach request message for attaching to an LTE cell to the simulation platform, and completes an attach procedure of the terminal in the LTE cell, where the TDSCDMA cell is a cell where the terminal resides after reselecting from a GSM cell; for example, in a specific example, after the terminal is powered on, the terminal registers to a GSM cell, after the terminal resides in the TDSCDMA cell for a first time period, the simulation platform activates the TDSCDMA cell to reduce the signal strength of the GSM cell, so that the terminal reselects to the TDSCDMA cell, and after the terminal resides in the TDSCDMA cell for a second time period, the TDSCDMA cell is deactivated, so that the terminal enters an OOS state, and then the terminal initiates an attach request message for attaching to an LTE cell.

Further, in practical application, before receiving an attach request message for attaching to a long term evolution LTE cell sent by a terminal, the method further includes: activating an LTE cell; and further, after the LET cell is activated, receiving an attachment request message for attaching the LTE cell sent by the terminal, establishing a Default evolved packet system (EPS bearer), and completing an attachment process of the terminal on the LTE cell.

Here, in this embodiment, before step 301, the method further includes: establishing a simulation network environment; correspondingly, the GSM cell, the TDSCDMA cell and the LTE cell are respectively corresponding to the GSM cell, the TDSCDMA cell and the LTE cell in the simulation network environment, namely, a network interacting with the terminal is a network in the simulation network environment, so that a foundation is laid for rapidly reselecting the terminal to a network scene according to a resident record after the LTE system with a small probability in the recurrent network enters an OOS state.

It should be noted that, in practical applications, the precondition for performing the attach procedure between the terminal and the network is that the terminal and the network complete a Radio Resource Control (RRC) connection establishment procedure. For example, the terminal sends an RRC connection establishment request message to the network; the network returns RRC connection establishment response information to the terminal; the terminal sends an RRC connection setup complete message to the network, and then, a procedure for the terminal to attach to the network is performed. That is, before the terminal performs an attach procedure with the network side, the terminal needs to perform a random access procedure with the network side. Here, the random access procedure may include: the terminal sends a random access request message (Msg1) to the base station, wherein a preamble is carried; after receiving the message, the base station sends a random access response message (Msg2) to the terminal; after receiving the message, the terminal sends an RRC connection establishment request message (Msg3) to the base station; after receiving the message, the base station sends an RRC connection establishment message (Msg4) to the terminal; the terminal sends an RRC connection setup complete message (which may be sent through SIB 1) to the base station.

Step 302: judging whether a Radio Resource Control (RRC) connection establishment request message initiated by the terminal and accessed to the TDSCDMA cell can be received within a preset time length, wherein the RRC connection establishment request message is initiated without a transmission frequency scanning step when the signal intensity of the LTE cell is lower than a first threshold value so that the terminal enters an OOS state, the signal intensity of the TDSCDMA cell is higher than a second threshold value, and the signal intensity of the GSM cell is higher than a third threshold value;

in this embodiment, after the simulation platform receives an attach request message for attaching to an LTE cell sent by a terminal and completes an attach procedure, the signal strength of the LTE cell is reduced and is reduced to be lower than a first threshold value, so that the terminal enters an OOS state again, and if the signal strength is reduced to be lower than the first threshold value and lasts for a period of time, the terminal enters the OOS state again; further, after the simulation platform increases the signal strength of the TDSCDMA cell to be higher than the second threshold value and increases the signal strength of the GSM cell to be higher than the third threshold value, the simulation platform determines whether the RRC connection setup request message initiated by the terminal without the transmission frequency scanning step and accessing the TDSCDMA cell can be received within a preset time period.

Here, the first threshold may specifically be a first access threshold for accessing the LTE cell, that is, after the signal strength of the LTE cell is higher than the first access threshold, the terminal is convenient to search for the LTE cell and then access the LTE cell. Similarly, the second threshold may specifically be a second access threshold for accessing a TDSCDMA cell, that is, after the signal strength of the TDSCDMA cell is higher than the second access threshold, the terminal is convenient to search for the TDSCDMA cell and then access the TDSCDMA cell; the third threshold may specifically be a third access threshold for accessing the GSM cell, that is, after the signal strength of the GSM cell is higher than the third access threshold, the terminal is convenient to search for the GSM cell and then access the GSM cell.

Step 303: and determining whether the terminal can reselect to the TDSCDMA cell based on the judgment result.

In this embodiment, the determining whether the terminal can reselect the TDSCDMA cell based on the determination result may specifically be: receiving an RRC connection establishment request message initiated by the terminal and accessed to the TDSCDMA cell within a preset time length; and judging whether the network side can perform reselection of the terminal to the TDSCDMA cell after receiving the RRC connection establishment request message for accessing the TDSCDMA cell. Further, if receiving a routing area update RAU complete message of the terminal in the TDSCDMA cell, determining that the terminal can complete an RAU procedure in the TDSCDMA cell, that is, indicating that the terminal can reselect the TDSCDMA cell, and further indicating that the optimization scheme is successful.

The method provided by the embodiment of the invention is applied to the process that a terminal executes network access by adopting a preset optimization scheme, and particularly, the attachment process of the terminal on an LTE cell is completed by receiving the attachment request message of an attachment long term evolution LTE cell sent by the terminal, wherein the terminal is in an OOS state of a non-service area entered after a Time Division Synchronous Code Division Multiple Access (TDSCDMA) cell is deactivated, and the TDSCDMA cell is a cell where the terminal resides after being reselected from a global system for mobile communications (GSM) cell; judging whether a Radio Resource Control (RRC) connection establishment request message initiated by the terminal and accessed to the TDSCDMA cell can be received within a preset time length, wherein the RRC connection establishment request message is initiated without a transmission frequency scanning step when the signal strength of the LTE cell is lower than a first threshold value so that the terminal enters an OOS state, the signal strength of the TDSCDMA cell is higher than a second threshold value, and the signal strength of the GSM cell is higher than a third threshold value; and then determining whether the terminal can reselect to the TDSCDMA cell based on the judgment result, thus, by adopting the scheme provided by the embodiment of the invention, the scene that the terminal can quickly reselect to the network according to the resident record after the original LTE signal loss which occurs with small probability in the network enters the OOS state can be reproduced, and the feasibility and the stability of the scheme that the terminal quickly reselects to the network according to the resident record after the LTE system enters the OOS state can be verified.

Moreover, because the network interacting with the terminal is a network in a simulation network environment, the embodiment of the invention adopts a simulation mode without a worker going to the site, and can remove other factors influencing detection, thereby greatly reducing the cost of the worker, and simultaneously eliminating the influence of other factors on the detection result under the scene described by the embodiment of the invention.

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

In the embodiment of the application, a network environment is constructed through a simulation platform, wherein the network environment comprises a TDD-LTE cell, a TDSCDMA cell and a GSM cell; the LTE SIB5 is configured with TDSCDMA neighboring cell information, the LTE SIB7 is configured with GSM neighboring cell information, and the GSM SI is configured with LTE neighboring cell information.

Here, in this example, three timers are involved, named Timer 0, Timer1, and Timer. Further, on the basis of the simulation platform, the method for detecting the network access result in the embodiment of the application includes:

step A: the UE is started and registered to a GSM cell, and after the residence time reaches timer 0, the simulation platform activates a TDSCDMA cell of a neighboring cell; further, the emulation platform reduces the signal strength of the GSM cell to cause the UE to reselect to the TDSCDMA cell, and after the dwell time reaches a timer1, the emulation platform deactivates the TDSCDMA cell and the UE enters an OOS state.

Here, in practical applications, the simulation platform and/or the UE records the residence record, such as but not limited to the following information contained in the residence record: the identity of the resident cell, the residence time duration, etc.

And B: and the simulation platform activates the LTE cell, correspondingly, the UE initiates an Attach (Attach) process to the LTE cell, registers the Attach process to the LTE cell, establishes a Default EPS bearer and completes the Attach process.

And C: the simulation platform reduces the signal strength of the current LTE cell and maintains the signal strength for a period of time so that the UE enters an OOS state.

Step D: and the simulation platform improves the signal strength of the GSM cell and the TDSCDMA cell, and correspondingly improves the signal strength to be higher than an access threshold TH 1/an access threshold TH2, and the UE starts to initiate a network searching process.

Step E: the simulation platform detects whether the UE can directly initiate an RRC connection establishment request to the TDSCDMA cell in a specified Timer (namely in a preset time length) without a power scan step, and carries a correct access request reason value. Here, if the simulation platform receives the RRC connection establishment request sent by the UE to the TDSCDMA cell within the specified Timer, step F is executed; otherwise, the UE is considered not to be reselected to the TDSCDMA cell.

Step F: the simulation platform detects whether the network side starts the subsequent process of the reselection of the TDSCDMA cell, for example, verifies whether the UE can successfully complete the RAU process on the TDSCDMA cell, so as to judge whether the UE can reselect the TDSCDMA cell.

Specifically, if the simulation platform receives an RAU request initiated by the UE, performs an RAU procedure, sends an RAU accept (RAU accept) message to the UE, and further receives an RAU Complete (RAU Complete) message sent by the UE, it is determined that the terminal can Complete the RAU procedure in the TDSCDMA cell, so as to indicate that the terminal can reselect the TDSCDMA cell, and the optimization scheme is successful. Otherwise, it indicates that the UE cannot reselect the TDSCDMA cell, and the optimization scheme fails.

Therefore, through the process, after the OOS of the LTE system which appears in the network with small probability is stably reproduced in a laboratory, the terminal can quickly reselect to the scene of the network according to the resident record, and the feasibility and the stability of the optimization scheme of quickly searching the network by the terminal according to the resident record after the OOS of the LTE system are verified.
