Abstract

This application relates to the field of communications technologies, and in particular, to an auxiliary-link-based call compensation system and apparatus, and chip. The system includes: a first terminal, a second terminal, and a core network device. The first terminal and the second terminal establish a primary link in response to a dialing operation entered by a user. The first terminal and the second terminal establish at least one auxiliary link in response to an auxiliary link establishment condition. The first terminal transmits call data packets with the second terminal by using the primary link and the at least one auxiliary link. The first terminal and/or the second terminal performs post-processing and playing on the call data packets received by using the primary link and the at least one auxiliary link.

First claim

What is claimed is:

1 . An apparatus, wherein the apparatus is configured to control a first terminal to perform:
establishing at least one auxiliary link with a second terminal in response to an auxiliary link establishment condition, wherein the first terminal and the second terminal are connected through a primary link established using a core network device, wherein the at least one auxiliary link is different from the primary link, wherein the primary link is connected via an access network element device, and wherein the at least one auxiliary link is independent of the access network element device; and transmitting call data packets with the second terminal by using the primary link and the at least one auxiliary link.

2 . The apparatus according to claim 1 , wherein the at least one auxiliary link is one of:
a point-to-point auxiliary link established according to an internet protocol (IP) protocol or a device to device (D2D) protocol; a server auxiliary link established according to an IP protocol or a D2D protocol; a core network link based on a base station, wherein both the first terminal and the second terminal are connected to the core network device by using the base station; or a core network link based on a wireless fidelity (Wi-Fi) device, wherein both the first terminal and the second terminal are connected to the core network device by using the Wi-Fi device.

3 . The apparatus according to claim 2 ,
wherein the primary link is the core network link based on the base station, and the at least one auxiliary link is one of the point-to-point auxiliary link, the server auxiliary link, the core network link based on the Wi-Fi device or a second base station; or wherein the primary link is the core network link based on the Wi-Fi device, and the at least one auxiliary link is one of the point-to-point auxiliary link, the server auxiliary link, the core network link based on the base station or a second Wi-Fi device.

4 . The apparatus according to claim 2 , wherein, based on the at least one auxiliary link being the point-to-point auxiliary link, that the first terminal establishes the at least one auxiliary link with the second terminal comprises:
the first terminal sends an IP address and a port number of the first terminal to the second terminal by using the primary link; the first terminal receives a first link detection command sent by the second terminal, wherein the first link detection command indicates whether the IP address and the port number of the first terminal can be used to successfully receive a message; and the first terminal sends a first response message to the second terminal based on the first link detection command.

5 . The apparatus according to claim 2 , wherein, based on the at least one auxiliary link being the point-to-point auxiliary link, that the first terminal establishes the at least one auxiliary link with the second terminal comprises:
the first terminal receives an IP address and a port number of the second terminal by using the primary link; the first terminal sends a second link detection command to the second terminal, wherein the second link detection command indicates whether the IP address and the port number of the second terminal can be used to successfully receive a message; and the first terminal receives a second response message sent by the second terminal, wherein the first terminal responds to the second link detection command based on the second response message.

6 . The apparatus according to claim 2 , wherein, based on the at least one auxiliary link being the server auxiliary link, that the first terminal establishes the at least one auxiliary link with the second terminal comprises:
the first terminal sends an auxiliary link establishment request to a server, wherein the auxiliary link establishment request carries a second feature identifier of the second terminal, and wherein the server sends the auxiliary link establishment request to the second terminal based on the second feature identifier; and the first terminal receives a response message sent by the second terminal, wherein the first terminal responds to the auxiliary link establishment request based on the response message.

7 . The apparatus according to claim 2 , wherein, based on the at least one auxiliary link being the server auxiliary link, that the first terminal establishes the at least one auxiliary link with the second terminal comprises:
after the primary link is established, the first terminal and the second terminal each actively establish a connection to a server to form the server auxiliary link.

8 . The apparatus according to claim 2 , wherein, based on the at least one auxiliary link being the point-to-point auxiliary link or the server auxiliary link, the first terminal and the second terminal establish the at least one auxiliary link by using Wi-Fi or cellular data.

9 . The apparatus according to claim 8 , wherein, based on both the first terminal and the second terminal establishing the at least one auxiliary link by using Wi-Fi, the at least one auxiliary link is always used to transmit a call data packet until a call ends after the at least one auxiliary link is established successfully, or the at least one auxiliary link transmits a call data packet in only a process in which call quality is abnormal.

10 . The apparatus according to claim 8 , wherein, based on at least one of the first terminal and the second terminal establishing the at least one auxiliary link by using the cellular data, the at least one auxiliary link being always used to transmit a call data packet after the at least one auxiliary link is established successfully, or the at least one auxiliary link being used to transmit a call data packet in only a process in which call quality is abnormal on the primary link.

11 . The apparatus according to claim 8 , wherein, based on both a first subscriber identity module (SIM) card and a second SIM card being installed in the first terminal, based on a current call card of the first terminal being the first SIM card, and based on a movement rate of the first terminal being greater than a rate threshold, the first terminal preferably uses cellular data of the second SIM card in a process of establishing the at least one auxiliary link.

12 . The apparatus according to claim 1 , wherein the auxiliary link establishment condition comprises at least one of:
the first terminal receives a dialing operation entered by a user; the first terminal displays a ringing interface; the first terminal receives a call answering operation entered by a user; the first terminal is currently in an abnormal geographical location; the first terminal is being handed over from a first abnormal cell to a second abnormal cell; or call quality of the first terminal is abnormal on the primary link, wherein the abnormal geographical location, the first abnormal cell, and the second abnormal cell are determined by the first terminal based on a historical call process of the first terminal.

13 . The apparatus according to claim 12 , wherein the auxiliary link establishment condition is that the call quality of the first terminal is abnormal on the primary link, and wherein that the call quality is abnormal comprises one of:
uplink or downlink quality is abnormal; uplink or downlink data transmission quality is abnormal; an encoding format of a call data packet is a preset encoding format on the primary link; or at least one of a sampling rate, an encoding rate, encoding quality, resolution, a frame rate, a quantity of sound channels, or a mean opinion score (MOS) value of th
