Detailed Description
At present, a mobile terminal is generally divided into an idle state and a service state in a mobile communication network, wherein the idle state refers to a state that the mobile terminal resides in a cell, does not establish a link with the network, and only monitors system messages and paging messages; the service state means that a service bearing link is established with the network and data can be transmitted or sent. The base station where the resident cell of the mobile terminal is located often fails in performance due to dominant failure or recessive failure, and the mobile terminal in an idle state does not establish a link with the network, so that the problem of performance failure in the resident cell cannot be effectively perceived, and when the mobile terminal initiates a service to access the performance-failed cell, the problem of access failure or abnormal use occurs.
In the prior art, a method for recording a cell with access failure and setting a timer for a serving cell with access failure is used to prevent a mobile terminal from accessing the cell with performance failure again, and the method comprises the following steps:
(a) when the mobile terminal initiates a service to perform cell access and encounters access failure, recording the information of a service cell with the access failure;
(b) when the mobile terminal constructs a serving cell reselection measurement list, all recorded serving cells with access failure are removed, and then cell reselection measurement is triggered;
(c) the mobile terminal evaluates the service cells in the reselection measurement result, sequentially selects one of the service cells meeting the cell reselection evaluation criterion, judges whether the service cell meets the cell residence condition or not, and executes the next step if the service cell meeting the cell residence condition exists;
(d) camp on the serving cell and re-initiate serving cell access.
However, it takes time to reselect to another cell, which may cause service interruption, and this method is a remedy after the access failure problem has occurred, so as to avoid the mobile terminal from appearing the problem again, that is, the mobile terminal has been affected by the performance failure cell, and therefore, this method has a poor effect of protecting the mobile terminal from the performance failure cell.
In order to solve the above technical problem, in the scheme provided by the present disclosure, when the mobile terminal accesses to and resides in a cell, it may be detected in advance whether the cell in which the mobile terminal resides is a performance failure cell, and if the cell in which the mobile terminal resides is the performance failure cell, the cell may be reselected to another cell satisfying the residence condition, so as to better protect the mobile terminal from the influence of the performance failure cell.
Fig. 1 is a flowchart illustrating a method for detecting a performance-failing cell according to an exemplary embodiment of the present disclosure.
As shown in fig. 1, the method for detecting a performance failure cell provided in this embodiment includes:
The method provided by the present disclosure may be performed by a mobile terminal, and when the mobile terminal camps on a cell, the mobile terminal may determine whether the cell where the mobile terminal camps is a resident cell of the mobile terminal.
The mobile terminal is a User Equipment (UE) that can access a wireless network, such as a mobile phone and a computer.
A plurality of cells (Radio Remote units, RRUs) may be set in one base station (Building base station Unit, BBU). Each cell has its own antenna to transmit signals, and the frequency points of each cell have their own different identifications. The cell may manage resources (resources include internet resources, telephony communication resources, etc. within the cell). The resources are independent from cell to cell.
The resident cell refers to a cell in which the mobile terminal has a longer residence time, and the mobile terminal is in an idle state. The idle state refers to that the mobile terminal resides in a cell, does not establish a link with the network, and only monitors system messages and paging messages, i.e., no Radio Resource Control (RRC) connection is established between the mobile terminal and the cell.
Specifically, the residence time of the mobile terminal in a cell may be determined, and if the residence time is too long, the cell where the mobile terminal currently resides may be determined to be the resident cell of the mobile terminal.
The base station where the cell where the mobile terminal resides is often disabled due to dominant failure or recessive failure, resulting in a performance-disabled cell. When the mobile terminal initiates a service to access a cell with a failed performance, the problem of access failure or abnormal use can occur.
Specifically, although the mobile terminal does not access the network of the residential cell, there is another communication with the residential cell, for example, the residential cell may send a broadcast message to the mobile terminal in the cell, and therefore, it may be determined whether the residential cell is a performance failure cell according to the communication information between the mobile terminal and the residential cell.
In practical application, if the communication information between the mobile terminal and the resident cell is normally interacted, the resident cell is not a performance failure cell; and if the communication information between the mobile terminal and the resident cell is not normally interacted, the resident cell is a performance failure cell.
And 103, if the resident cell is determined to be the performance failure cell, reselecting other target cells meeting the resident conditions, and residing in the target cells.
Specifically, if it is determined that the resident cell is a performance failure cell, it may be determined that an error occurs when the mobile terminal establishes a link with the network of the cell, and therefore, a preset reselection mechanism in the mobile terminal may be started, and another target cell meeting the residence condition may be reselected and resided in the target cell.
Further, when camping on the target cell, the mobile terminal may further determine whether the target cell is a performance failure cell based on the scheme of the present disclosure.
Further, the mobile terminal may obtain a list of cells satisfying the camping condition, and select a target cell from the list.
The method for detecting the cell with the performance failure provided by the disclosure comprises the following steps: when the mobile terminal resides in the cell, determining whether the resident cell is a resident cell of the mobile terminal; if the resident cell is determined to be the resident cell of the mobile terminal, determining whether the resident cell is a performance failure cell according to communication information between the mobile terminal and the resident cell; and if the resident cell is determined to be the performance failure cell, reselecting other target cells meeting the resident conditions, and residing in the target cells. According to the method adopted in the disclosure, when the mobile terminal accesses the cell and resides in the cell, whether the cell where the mobile terminal resides is a performance failure cell or not can be detected in advance, and if the cell where the mobile terminal resides is the performance failure cell, other cells meeting the residence conditions can be reselected, so that the mobile terminal is better protected from the influence of the performance failure cell.

Specifically, after step 201, step 202A, or step 202B may be performed.
The residence time monitoring timer is a timer preset in the mobile terminal. When the mobile terminal resides in the cell, the residence time duration monitoring timer is started immediately. Therefore, the states of the timer and the mobile terminal are monitored by using the residence time, and whether the cell where the mobile terminal resides is the resident cell of the mobile terminal is determined.
The timeout duration of the residence duration monitoring timer is a time value preset according to actual conditions.
The service state refers to that the mobile terminal and the cell establish a service bearer link and can transmit or send data, that is, Radio Resource Control (RRC) connection is established between the mobile terminal and the cell. If the mobile terminal enters the service state, it can be determined that the cell where the mobile terminal resides is not the resident cell of the mobile terminal.
The mobile terminal reselects to another cell, which means that the mobile terminal no longer resides in the cell but resides in another cell. At this time, it may be determined that the cell in which the mobile terminal resides is not a resident cell of the mobile terminal.
Specifically, after step 202B, step 203A, or step 203B may be performed.
Specifically, if the resident duration monitoring timer is started to be overtime, the mobile terminal is not reselected to other cells all the time and the mobile terminal is in an idle state all the time, and the resident cell is determined to be the resident cell of the mobile terminal.
The communication information comprises a message sent by the resident cell to the mobile terminal, wherein the message is sent to the mobile terminal by the resident cell at regular time.

In one implementation, the message comprises a system message; the preset duration is the effective duration of the system message of the resident cell;
wherein, the system message includes parameter configuration information of the cell; the cell sends the system message to the mobile terminal regularly (for example, once in 10 s); when the parameter configuration information of the cell changes, the cell also sends a system message to the mobile terminal.
Specifically, the system message transmission rule may be modified in the cell, where the transmission rule may include time interval information of the timing transmission. Wherein, the time interval of the timing transmission is the effective duration of the system message.
Starting a system message monitoring timer; the timeout duration of the system message monitoring timer is equal to or greater than the effective duration of the system message of the resident cell;
specifically, if the resident cell is determined to be a resident cell, the system message monitoring timer is started immediately.
The system message monitoring timer is a preset timer. The timeout duration of the system message listening timer may be preset according to an actual situation, for example, may be set to be equal to or greater than the effective duration of the system message of the residential cell. For example, the timeout duration of the system message listening timer may be set to 10 s.
If the mobile terminal receives the system message sent by the resident cell before the system message monitoring timer is overtime, determining that the mobile terminal receives the message sent by the resident cell within a preset time length;
specifically, if the mobile terminal receives a message sent by the residential cell within a preset time, it may be determined that the residential cell is not a performance failure cell.
Optionally, if the mobile terminal receives the system message sent by the residential cell before the system message monitoring timer expires, the system message monitoring timer is set to zero, and the system message monitoring timer is used to restart timing.
Specifically, if the mobile terminal receives the system message sent by the residential cell before the system message monitoring timer expires, the system message monitoring timer is set to zero, and the system message monitoring timer is used to restart timing to perform the next round of system message monitoring.
And if the mobile terminal does not receive the system message sent by the resident cell before the system message monitoring timer is overtime, determining that the mobile terminal does not receive the message sent by the resident cell within the preset time length.
Specifically, in the monitoring process of the system message in one round, if the system message monitoring timer is from zero to overtime and the mobile terminal does not receive the system message sent by the residential cell, it is determined that the mobile terminal does not receive the message sent by the residential cell within the preset time.
In one implementation, the message comprises a paging message; the preset duration is the network paging cycle of the resident cell;
the paging message may include a called paging message and a paging message when a cell system message is changed; the cell may send paging messages to the mobile terminal periodically (e.g., once in 5 s).
Specifically, the transmission rule of the paging message may be modified in the cell, wherein the transmission rule may include time interval information of the timing transmission. Wherein, the time interval of the timing transmission is a network paging cycle.
Starting a paging message monitoring timer; the time-out duration of the paging message monitoring timer is equal to or greater than the network paging cycle of the resident cell;
specifically, if the resident cell is determined to be a resident cell, the paging message monitoring timer is started immediately.
The paging message monitoring timer is a preset timer. The timeout duration of the paging message listening timer may be preset according to an actual situation, for example, may be set to be equal to or greater than a network paging cycle of a residential cell. For example, the timeout duration of the paging message listening timer may be set to 5 s.
If the mobile terminal receives the paging message sent by the resident cell before the paging message monitoring timer is overtime, determining that the mobile terminal receives the message sent by the resident cell within a preset time length;
specifically, if the mobile terminal receives the paging message within the preset time period, it may be determined that the resident cell is not a performance failure cell.
Optionally, if the mobile terminal receives the paging message sent by the residential cell before the paging message monitoring timer expires, the paging message monitoring timer is set to zero, and the paging message monitoring timer is used to restart timing.
Specifically, if the mobile terminal receives the system message sent by the resident cell before the paging message monitoring timer expires, the paging message monitoring timer is set to zero, and the paging message monitoring timer is used to restart timing to perform the next round of paging message monitoring.
And if the paging message monitoring timer is overtime and the mobile terminal does not receive the paging message sent by the resident cell, determining that the mobile terminal does not receive the message sent by the resident cell within the preset time length.
Specifically, in a round of paging message monitoring process, when the paging message monitoring timer is from zero to overtime, and the mobile terminal does not receive the paging message sent by the resident cell, it is determined that the mobile terminal does not receive the message sent by the resident cell within a preset time length.
Specifically, step 204 may be performed after step 203B.
Wherein, N is a value preset according to actual conditions.
In one implementation mode, the access information comprises a random access request sent by the mobile terminal to the resident cell and a response message sent by the resident cell corresponding to the random access request to the mobile terminal;
specifically, the random access request sent by the mobile terminal to the residential cell has a one-to-one correspondence with the response message sent by the residential cell to the mobile terminal.
Controlling the mobile terminal to send random access requests to the resident cell every second preset time within a first preset time until the number of the sent random access requests reaches N; the first preset time is greater than the product of the second preset time and N; n is a positive integer;
the first preset time is a time value preset according to actual conditions, and may be 60s, for example.
The second preset time is a time value preset according to an actual situation, and may be 1s, for example.
Where N is a value preset according to a time situation, and may be set to 15, for example.
Acquiring a response message which is received by a mobile terminal and sent by a resident cell and corresponds to a random access request;
specifically, if the resident cell receives a random access request sent by the mobile terminal, a response message corresponding to the random access request is sent to the mobile terminal.
And step 204, determining the success times of the access network according to the communication information, and determining whether the resident cell is a performance failure cell according to the success times.
Specifically, if the mobile terminal receives a response message corresponding to the random access request sent to the residential cell, it indicates that this time the network access is successful.
Specifically, if the total number of the random access requests sent by the mobile terminal to the residential cell is N, the number of times of success of accessing the network is less than or equal to N. Specifically, if the success times meet a preset condition, determining that the resident cell is not a performance failure cell; and if the success times do not meet the preset conditions, determining the resident cell as a performance failure cell.
In one implementation manner, the number of response messages received in a first preset time is determined according to the communication information;
specifically, if the mobile terminal receives a response message corresponding to the random access request sent to the residential cell, it indicates that the network is successfully accessed once. Only after the resident cell receives the random access request sent by the mobile terminal, the response message is sent to the mobile terminal; therefore, the number of response messages received by the mobile terminal within the first preset time may indicate the number of times of success of accessing the network.
The preset condition is preset according to an actual situation, for example, the ratio of the number of times of successful network access within the first preset time to the number N of random access requests sent may be 55%.
And determining whether the resident cell is a performance failure cell according to the number of the random access requests sent in the first preset time and the number of the received response messages.
Specifically, if the number of random access requests sent within a first preset time and the number of received response messages meet preset conditions, it is determined that the residential cell is not a performance failure cell; and if the number of the random access requests sent within the first preset time and the number of the received response messages do not meet the preset conditions, determining the resident cell as a performance failure cell.
The preset condition is preset according to actual conditions, and for example, the ratio of the number of response messages received within the first preset time to the number of random access requests sent may be 55%.
Optionally, acquiring a preset threshold;
the preset threshold is a preset value according to actual conditions, and may be 55%, for example.
If the ratio of the number of the response messages to the number of the random access requests is larger than or equal to a preset threshold value within a first preset time, determining that the resident cell is a performance failure cell;
and if the ratio of the number of the response messages to the number of the random access requests is smaller than a preset threshold value in the first preset time, determining that the resident cell is not the cell with the performance failure.
In an implementation manner, if it is determined that the resident cell is not the performance failure cell, the step of controlling the mobile terminal to access the network in the resident cell for N times is continuously performed within the next first preset time.
Specifically, if it is determined that the residential cell is not the performance failure cell, the mobile terminal will stop sending the random access request to the residential cell until the time enters the next first preset time, and will continue to execute the step of controlling the mobile terminal to access the network in the residential cell for N times to obtain the communication information.
Specifically, if it is determined that the resident cell is a performance failure cell, a preset reselection mechanism in the mobile terminal is started, and another target cell meeting the resident condition is reselected and resides in the target cell.
Further, a cell list satisfying the camping condition may be obtained, and a target cell may be selected from the list.
Specifically, the timeout duration of the expiration timer is preset according to actual conditions, and may be set to 10 hours, for example.
Specifically, before the expiration timer expires, the performance-failing cell will not appear in the cell list satisfying the camping condition; the mobile terminal will not reselect to the performance failing cell.
Fig. 3 is a schematic diagram illustrating a detection process of a performance failing cell according to an exemplary embodiment of the present disclosure.
