Description

Method and device for correcting IMS registration state
Technical Field
The present invention relates to the field of communications technologies, and in particular, to a method and an apparatus for correcting an IMS registration status.
Background
Voice over LTE (Voice over LTE, Voice service based on LTE network) refers to an IMS (IP Multimedia Subsystem) based Voice service configured on an LTE (Long Term Evolution) network, and can provide high-quality audio/video calls and greatly improve call quality.
When the terminal and the network in which the terminal is located both support the voice service, only the 4G (the 4th Generation communication system, fourth Generation mobile communication technology) network, that is, the LTE network, supports the voice service, and the terminal initiates IMS initial registration after being powered on. After the registration is successful, the terminal displays an HD (high definition) or a volume icon in the status bar. When the terminal switches from 4G mode to flight mode or 3G (the 3rd generation communication system, third generation mobile communication technology) mode, the terminal triggers IMS logout. Sometimes, after the IMS deregistration request is sent, the feedback of the IMS core network server is not received in a delayed manner. When the terminal is switched to the flight mode or the 3G mode, the terminal can be separated from the LTE network, and because the IMS is a technology which needs to be realized based on the LTE network, when the terminal is separated from the LTE network, the terminal actually completes IMS logout, and the terminal can not support the Voice over Voice service. At this time, since the terminal does not receive the feedback from the IMS core server, the HD or volume icon is also displayed in the terminal status bar in error, as shown in fig. 1, the HD or volume icon is still displayed in error while the terminal is already in the flight mode.
In the case that the terminal status bar erroneously displays the HD or the volume icon, when switching from the flight mode or the 3G mode to the 4G mode, that is, the LTE mode, the terminal initiates IMS registration to the IMS core network server, and if registration fails within a preset time, the terminal status bar still continuously and erroneously displays the HD or the volume icon. As shown in fig. 2, the LTE mode is performed and the status bar displays the HD or voice icon, but in practice, IMS registration fails and voice service is not supported. The user may misinterpret the user by displaying the HD or the voice icon in the status bar indicating that a voice call can be made, but that each call is a normal call.

Detailed Description
In order to make the aforementioned objects, features and advantages of the present invention comprehensible, embodiments accompanied with figures are described in detail below. In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present invention. This invention may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein, but rather should be construed as broadly as the present invention is capable of modification in various respects, all without departing from the spirit and scope of the present invention.
Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs. The terminology used in the description of the invention herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The technical features of the above embodiments can be arbitrarily combined, and for the sake of brevity, all possible combinations of the technical features in the above embodiments are not described, but should be considered as the scope of the present specification as long as there is no contradiction between the combinations of the technical features.
The method for correcting the IMS registration status provided in the embodiment of the present invention may be applied to an application environment as shown in fig. 3. The terminal 302 is connected to an IMS core network server 304 through a network, and the terminal 302 is connected to an LTE network server 306 through the network. The terminal 302 acquires the network state change event and generates an IMS logout request in response to the network state change event. The terminal 302 sends the IMS logout request to the IMS core network server 304, and determines whether the terminal receives a feedback message of successful IMS logout returned by the IMS core network server. If not, marking that IMS logout is not finished. And detecting the LTE network connection state, judging whether the terminal receives a feedback message of successful IMS logout returned by the IMS core network server again before the LTE network connection is disconnected, if not, acquiring an IMS registration state icon after the LTE network connection is disconnected, and hiding the IMS registration state icon.
In an embodiment, as shown in fig. 4, a method for correcting an IMS registration state is provided, which is described by taking the method as an example applied to the terminal 102 in fig. 1, and specifically includes:
step 402, acquiring a network state change event, and responding to the network state change event to generate an IMS logout request.
The network state change event includes: switching from LTE mode to airplane mode or from LTE mode to 3G mode. The flight mode is a mode of closing the telephone communication function, namely, a mode of not receiving and calling and sending short messages. 3G is a third generation mobile communication technology, and currently, 3 standards exist in 3G: CDMA2000, WCDMA, TD-SCDMA. The terminal is disconnected from the LTE network in the airplane mode, and is also disconnected from the LTE network in the 3G mode. Since IMS is a technology that needs to be implemented based on an LTE network, when a terminal acquires a network state change event, the terminal needs to generate an IMS logout request for disconnecting from an IMS core network server in response to the network state change event.
Step 404, sending the IMS deregistration request to an IMS core network server.
And after generating the IMS logout request, the terminal sends the IMS logout request to an IMS core network server. Generally, after receiving an IMS deregistration request, an IMS core network server deletes registration information of a terminal on the IMS core network server according to the IMS deregistration request, thereby disconnecting the terminal from the IMS core network server.
Step 406, determining whether a feedback message of successful IMS deregistration returned by the feedback message IMS core network server is received within a preset time.
The terminal sends the IMS logout request to an IMS core network server, the IMS core network server receives the IMS logout request, deletes the temporary registration information of the user according to the IMS logout request, and then returns a feedback message to the terminal. And judging whether the terminal receives a feedback message returned by the IMS core network server. For example, the feedback message may be a SIP 200 OK. The terminal receives the feedback message and shows that the IMS logout is successful.
Step 408, if a feedback message of successful IMS deregistration returned by the IMS core network server is not received, marking that IMS deregistration is not completed.
And if the terminal does not receive the feedback message returned by the IMS core network server, marking that the IMS logout is not completed. The terminal may insert an identifier to mark the deregistered state of IMS deregistration. The identifier may be a preset character or string, for example the identifier is a TAG. If the terminal does not receive the feedback message returned by the IMS core network server within the preset time, the value of the identifier is set to a first value to mark that IMS logout is not completed, and the first value can be 0. Of course, in other embodiments, other values may be used to assign the identifier to mark that IMS deregistration has not been completed. For example, the terminal may insert an identifier to mark a deregistration state of IMS deregistration, and set a value of an identifier TAG to a first value to mark that IMS deregistration is not completed if the terminal does not receive a feedback message returned by an IMS core network server within a preset time.
The IMS logout is marked by inserting the identifier, so that whether the IMS logout is successful or not can be monitored, the IMS registration state can be corrected in time before the terminal is switched to the flight mode or the 3G mode, and the IMS registration state icon is hidden. Therefore, no matter whether the terminal receives the feedback message of successful IMS logout returned by the IMS core network server or not, the terminal does not display the IMS registration state icon in the flight mode or the 3G mode.
And step 410, detecting the LTE network connection state.
The terminal detects whether normal connection with the LTE network is kept.
Step 412, before the LTE network is disconnected, it is determined again whether a feedback message that the IMS deregistration is successful is received, where the feedback message is returned by the IMS core network server.
The terminal detects whether normal connection with the LTE network is kept. Before the information that the LTE network is disconnected and returned by the LTE network server is not received, whether a feedback message returned by the IMS core network server is received or not is judged again.
And step 414, if the feedback message of successful IMS logout returned by the IMS core network server is not received, acquiring an IMS registration state icon after the LTE network is disconnected, and hiding the IMS registration state icon.
After the disconnection of the terminal from the LTE network is detected, whether the terminal receives a feedback message returned by the IMS core network server is judged again, namely the value of the identifier is judged again. If the value of the identifier is still the first value, it indicates that IMS deregistration has not yet been completed. At this time, the terminal automatically changes the IMS registration state from unsuccessfully deregistered to successfully deregistered. And acquiring an IMS registration state icon, and hiding the IMS registration state icon from the terminal.
Because the IMS technology can be implemented based on the LTE network, when the terminal is switched from the LTE mode to the airplane mode or from the LTE mode to the 3G mode, the terminal is disconnected from the LTE network, and the terminal is also disconnected from the IMS core network server, so that the IMS registration state needs to be corrected to be successful logout.
In the traditional IMS logout mode, only if the terminal receives a feedback message returned by an IMS core network server, the IMS registration state can be modified to be successful in logout, and then an IMS registration state icon is hidden. Otherwise, the IMS registration status icon will always be displayed on the terminal. Therefore, if the terminal does not receive the feedback message returned by the IMS core network server, the IMS registration status icon is still displayed even in the flight mode or the 3G mode, and obviously, such display is not reasonable.
In this embodiment, after the terminal is switched from the LTE mode to the airplane mode or from the LTE mode to the 3G mode, the terminal will be disconnected from the LTE network. When the terminal acquires the network state change event, the terminal responds to the network state change event to generate an IMS logout request and sends the IMS logout request to an IMS core network server. And if the feedback message of successful IMS logout returned by the feedback message IMS core network server is not received within the preset time, the identifier is inserted to mark that the IMS logout is not completed within the preset time.
And the terminal detects the LTE network connection state again, and judges whether a feedback message of successful IMS logout returned by the IMS core network server is received again before the LTE network connection is disconnected. And if the terminal does not receive the feedback message returned by the IMS core network server, the terminal acquires the IMS registration state icon which is displayed in error, hides the IMS registration state icon and does not continue to display the IMS registration state icon. Thereby correcting erroneous display of the IMS registration status icon. The method avoids the error display of the IMS registration state icon on the terminal status bar in the flight mode or the 3G mode. As long as the terminal status bar is correctly displayed in the flight mode or the 3G mode, the situation that the terminal initiates IMS registration to the IMS core network server when the terminal is switched from the flight mode or the 3G mode to the LTE mode subsequently is avoided, and if the registration fails within the preset time, the terminal status bar still continuously and wrongly displays the HD or Volte icon is avoided. The display accuracy of the IMS registration state icon is effectively improved, and misunderstanding caused by users is avoided.
In one embodiment, before the step of detecting the LTE network connection status, the method further includes: generating an LTE network separation request; and sending the LTE network separation request to an LTE network server so that the LTE network server disconnects the LTE network connection according to the feedback message LTE network separation request.
The terminal generates an LTE network separation request and sends the LTE network separation request to the LTE network server, so that the LTE network server disconnects the LTE network connection according to the LTE network separation request. After the LTE network server disconnects the LTE network, the LTE network server sends the information that the LTE network is disconnected to the terminal.
In one embodiment, the step of marking that IMS deregistration has not been completed comprises: if the feedback message of successful IMS logout returned by the IMS service is not received within the preset time, inserting an identifier; the identifier is configured with a first value, with which the IMS deregistration is marked as not yet completed.
In this embodiment, the terminal may insert an identifier to mark a deregistration state of IMS deregistration. The identifier may be a preset character or string, for example the identifier is a TAG. If the terminal does not receive the feedback message returned by the IMS core network server within the preset time, the value of the identifier is set to a first value to mark that IMS deregistration is not completed, for example, the first value may be 0. Of course, in other embodiments, other values may be used to assign the identifier to mark that IMS deregistration has not been completed.
In one embodiment, after the step of determining whether a feedback message that IMS deregistration is successful is received, the method further includes: if a feedback message of successful IMS logout returned by the feedback message IMS core network server is received, the IMS logout is successful, and the feedback message identifier is configured to be a second value; and confirming that the IMS registration state is successful in logout, acquiring an IMS registration state icon, and hiding the feedback message IMS registration state icon.
In this embodiment, if the terminal receives a feedback message returned by the IMS core network server, the value of the identifier is set to the second value to mark that IMS deregistration is completed. For example, the second value may be 1. And the terminal receives a feedback message returned by the IMS core network server, and sets the value of the identifier as a second value to mark the completion of IMS logout. Of course in other embodiments, the identifier may be assigned with other values to mark the completion of IMS deregistration.
In one embodiment, the step of judging again whether a feedback message of successful IMS deregistration returned by the IMS core network server is received before the LTE network is disconnected includes: judging whether a numerical value corresponding to the identifier of the feedback message is a first value or not before the LTE network is disconnected; if yes, IMS logout fails; and acquiring an IMS registration state icon, and hiding the IMS registration state icon.
In this embodiment, before the terminal does not receive the information that the LTE network has been disconnected, which is returned by the LTE network server, it is determined again whether the value of the identifier TAG is the first value. If the value is the first value, the terminal determines that IMS logout fails, then acquires an IMS registration state icon, and hides the IMS registration state icon.
If the value of the identifier is judged to be the second value, the terminal confirms that the IMS logout is successful. The IMS registration status icon is hidden and then the value of the identifier is modified from the second value to the first value.
In one embodiment, as shown in fig. 5, there is provided an apparatus for correcting an IMS registration state, including: a generating module 502, a sending module 504, a judging module 506, a marking module 508, a detecting module 510 and a hiding module 512. Wherein:
