Self-adaptive adjustment method of video call service and video mobile terminal
A self-adaptive adjustment method of video call service and a video mobile terminal are disclosed in the present invention, wherein the method includes: the video mobile terminal receiving parameter information representing the channel capacity of a cell to which the video mobile terminal belongs; and the video mobile terminal adjusting quality of a video call that is being performed or will be initiated by the video mobile terminal according to the parameter information received by the video mobile terminal. By the present invention, the video mobile terminal is enabled to accomplish utilization of the video call service to a maximum extent in a limited channel capacity of the cell, and the user experience is improved.
1. A self-adaptive adjustment method of video call service, comprising:
a video mobile terminal receiving parameter information representing the channel capacity of a cell to which the video mobile terminal belongs, wherein the parameter information is percentage of a channel occupancy volume of the cell; and
the video mobile terminal adjusting quality of a video call that is being performed or will be initiated by the video mobile terminal according to the parameter information received by the video mobile terminal;
wherein the step of adjusting quality of the video call comprises adjusting a quality parameter of the video call or transforming the video call into a voice call.
2. The method according to claim 1 , wherein a process of the video mobile terminal adjusting the quality of the video call that is being performed or will be initiated comprises:
the video mobile terminal comparing the parameter information with a first predetermined value and a second predetermined value, wherein the second predetermined value is greater than the first predetermined value;
the video mobile terminal reducing the quality of the video call by adjusting a quality parameter of the video call that is being performed or will be initiated in a situation that the parameter information is greater than or equal to the first predetermined value and is smaller than or equal to the second predetermined value; and
the video mobile terminal reducing the quality of the video call by transforming the video call that is being performed or will be initiated into a voice call, in a situation that the parameter information is greater than the second predetermined value.
3. The method according to claim 2 , wherein the quality parameter comprises at least one of frame rate, picture quality and image color of a video.
4. The method according to claim 1 , wherein further comprising:
a base station or Mobile Switching Center monitoring a channel capacity of the cell, and sending the parameter information to the video mobile terminal with preset periodicity.
5. A video mobile terminal, comprising:
a receiving module configured to receive parameter information of a channel capacity of a cell to which the video mobile terminal belongs, wherein the parameter information is percentage of a channel occupancy volume in the cell; and
an adjusting module configured to adjust quality of a video call that is being performed or will be initiated by the video mobile terminal according to the parameter information received by the receiving module; wherein adjusting quality of the video call comprises adjusting a quality parameter of the video call or transforming the video call into a voice call.
6. The video mobile terminal according to claim 5 , wherein the adjusting module comprises:
a comparing module, configured to compare the parameter information with a first predetermined value and a second predetermined value, wherein the second predetermined value is greater than the first predetermined value;
a first adjusting sub-module, configured to reduce the quality of the video call by adjust a quality parameter of the video call that is being performed or will be initiated in a situation that the parameter information is greater than or equal to the first predetermined value and is smaller than or equal to the second predetermined value; and
a second adjusting sub-module, configured to reduce the quality of the video call by transforming the video call that is being performed or will be initiated into a voice call, in a situation that the parameter information is greater than the second predetermined value.
7. The video mobile terminal according to claim 6 , wherein the quality parameter includes at least one of frame rate, picture quality and image color of a video.
