Detailed Description
Technical solutions in the embodiments of the present application will be clearly described below with reference to the drawings in the embodiments of the present application, and it is apparent that the described embodiments are some embodiments of the present application, but not all embodiments. All other embodiments obtained by a person of ordinary skill in the art based on the embodiments in the present application are within the scope of the protection of the present application.
The terms first, second and the like in the description and in the claims, are used for distinguishing between similar objects and not necessarily for describing a particular sequential or chronological order. It is to be understood that the data so used may be interchanged where appropriate such that embodiments of the present application may be implemented in sequences other than those illustrated or described herein. Furthermore, in the description and claims, "and/or" means at least one of the connected objects, and the character "/", generally means that the associated object is an "or" relationship.
The call establishment method, the call establishment device, the electronic device and the readable storage medium provided in the embodiments of the present application are described in detail below with reference to the accompanying drawings by means of specific embodiments and application scenarios thereof.
The embodiment of the application provides a call establishment method, as shown in fig. 1, which includes:
In this embodiment, when the electronic device interrupts a call with the called party due to an abnormality in the first cell, the electronic device actively initiates a first connection request to the first cell, that is, initiates a redial procedure. In order to avoid long-time redial unresponsiveness, a count of the number of times of first connection requests is added, and when the number of times of first connection requests is initiated exceeds a preset threshold, the first cell is added to a forbidden cell list, and connection of the first cell is temporarily forbidden.
And step 106, skipping the cells in the forbidden cell list to select the cells, and sending a second connection request to the selected second cell so as to reestablish the call with the called party through the second cell.
In this embodiment, after the connection of the first cell is prohibited, the electronic device performs a cell selection procedure (in the case where the electronic device is in an idle state) or an RRC connection reestablishment procedure (in the case where the electronic device is in a connected state) in a selection range other than the cell of the prohibited cell list, and determines the second cell. And then re-initiating a second connection request to the second cell, thereby realizing normal call.
In the embodiment of the application, when a call is dropped due to abnormal cells, the electronic equipment actively initiates a redial flow, and in order to avoid long-time redial unresponsiveness, a redial count is added, and when the redial count exceeds a preset threshold, connection of the abnormal cells is temporarily prohibited, and the redial flow is initiated to other cells without the abnormality. By the mode, the purposes of improving the redial success rate and avoiding long-time call drop are achieved, and the continuity and success rate of call service are improved.
It should be noted that, the occurrence of the cell abnormality includes the situation that the network issues service restrictions such as RRC connection release during the call, and the network does not reestablish the dedicated bearer for the call, i.e., the electronic device cannot talk with the called party.
Further, in one embodiment of the present application, the call setup method further includes: timing is carried out while the first cell is added into the forbidden cell list, so as to obtain timing duration; and under the condition that the timing duration is greater than or equal to the preset duration, releasing the first cell from the forbidden cell list.
In this embodiment, when the number of redials initiated to the first cell is greater than a preset threshold, it is determined that the first cell is an abnormal cell, so that the first cell is added to the forbidden cell list, so as to avoid that the electronic device continues to send a redial request to the first cell. Because the abnormal cell may be abnormal in a short time, after the timing time for adding the first cell to the forbidden cell list reaches the preset time, the first cell is released from the forbidden cell list, so that the electronic device can also initiate a redial request to the first cell, and the success rate of the call service is improved.
It should be noted that, for each cell, there is an independently maintained timer for counting the storage time period of the cell in the forbidden cell list.
In a specific embodiment of the present application, as shown in fig. 2, the call establishment method includes:
In this embodiment, when the terminal (i.e., the electronic device) drops a call and the network does not recover the dedicated bearer, the terminal places the abnormal cell into the IMS call service and the blacklist of cell selection, sets a corresponding Timer a, performs a cell selection procedure (in the case that the electronic device is in an idle state) or an RRC connection reestablishment procedure (in the case that the electronic device is in a connected state), and then reinitiates the IMS call service. By the method, the abnormal call which is not recovered to bear by the network is subjected to continuous call processing, so that the purpose of improving the redial success rate and avoiding long-time call drop is achieved, inconvenience brought to a user due to network abnormality can be reduced, the call is automatically recovered, and the user experience is improved to a certain extent.
It should be noted that, the initial anomaly number is 0, and the anomaly number is reset to 0 when Timer a times out, that is, the anomaly number is not cleared after the call flow is initiated successfully, and the anomaly number is cleared when Timer a times out.
Further, in one embodiment of the present application, the call setup method further includes: and prohibiting reporting of the measurement report of the first cell under the condition that the number of times of the first connection request is larger than or equal to a preset threshold value.
In this embodiment, the measurement report is downlink measurement information about a neighboring cell sent by the electronic device to the network, and if the electronic device does not send the downlink measurement information, the network will not cut to the neighboring cell, so as to control a cell replacement function of a connection state, and avoid returning to an abnormal cell in a call. Therefore, through the mode, the normal conversation can be ensured.
Further, in one embodiment of the present application, after reestablishing the call with the called party through the second cell, the method further includes: judging whether the first cell is abnormal or not under the condition of switching from the second cell to the first cell; and under the condition that the first cell is abnormal and the timing duration is less than the preset duration, not re-timing.
In this embodiment, when it is determined that a certain cell has a problem, the Timer a of the cell will not be re-clocked. That is, when an abnormal cell (i.e., the first cell) with a dropped bearer is found, the abnormal cell is added into the forbidden cell list, but after the call is possibly restarted, the network is also switched from the second cell to the original abnormal cell with the dropped bearer, if the cell is identified as abnormal again, and the timer of the abnormal cell in the forbidden cell list does not reach the preset duration, the timer of the abnormal cell is not reset again, but continues to count, so as to avoid the influence on the success rate of the call service due to disordered timing.
Further, in one embodiment of the present application, the call setup method further includes: under the condition that the number of times of the first connection request is smaller than a preset threshold value, adding the first cell into a forbidden cell list; and skipping the cells in the forbidden cell list to perform cell selection, and initiating a connection request to the selected third cell so as to reestablish a call with the called party through the third cell.
In this embodiment, in the case where the number of times of the first connection request is greater than or equal to 0 and less than the preset threshold, the first cell is added to the forbidden cell list. That is, when the first cell is abnormal, the first cell is added into the forbidden cell list, and connection to the first cell is temporarily forbidden, so that the redial request is prevented from being sent to the abnormal cell, and the electronic equipment can quickly send the connection request to the non-abnormal cell, thereby improving the continuity of the call service.
In a specific embodiment of the present application, as shown in fig. 3, the call establishment method includes:
step 303, the terminal registers LTE or ENDC or SA normally, dials the called party and establishes IMS call;
In this embodiment, when a call drop occurs in the terminal (i.e., the electronic device described above) and the network does not recover the dedicated bearer, the terminal places the abnormal cell into the IMS call service and the blacklist of cell selection, sets a corresponding Timer a, performs a cell selection process (in the case that the electronic device is in an idle state) or an RRC connection reestablishment process (in the case that the electronic device is in a connected state), then reinitiates the call flow, and prohibits reporting of the measurement report of the abnormal cell to ensure that the call normally proceeds. By the method, the abnormal call which is not recovered to bear by the network is subjected to continuous call processing, so that the purpose of improving the redial success rate and avoiding long-time call drop is achieved, inconvenience brought to a user due to network abnormality can be reduced, the call is automatically recovered, and the user experience is improved to a certain extent.
It should be noted that, in the call establishment method provided in the embodiment of the present application, the executing body may be a call establishment device, or a control module in the call establishment device for executing the call establishment method. In the embodiment of the present application, a call establishment method performed by a call establishment device is taken as an example, and the call establishment device provided in the embodiment of the present application is described.
