Abstract
A connection recovery method includes searching, by a first terminal, for a recovery candidate corresponding to an interrupted connection; selecting, by the first terminal, one found recovery candidate as a first recovery candidate; sending, by the first terminal, a negotiation request to a second terminal; receiving, by the first terminal, a matching success message returned by the second terminal; and transmitting, by the first terminal, data to the second terminal according to the first connection information.
Claims17
A connection recovery method, comprising:
- searching, by a first terminal, for a recovery candidate corresponding to an interrupted connection, wherein the recovery candidate comprises connection information and a recovery identifier used to identify the connection information;
- selecting, by the first terminal, one found recovery candidate as a first recovery candidate, wherein the first recovery candidate comprises a first recovery identifier and first connection information;
- sending, by the first terminal, a negotiation request to a second terminal, wherein the negotiation request comprises the first recovery identifier of the selected first recovery candidate;
- receiving, by the first terminal, a matching success message returned by the second terminal, wherein the matching success message is used to indicate that the second terminal finds a second recovery candidate that has a same recovery identifier as the first recovery candidate;
- and
- transmitting, by the first terminal, data to the second terminal according to the first connection information and after receiving the matching success message.
A connection recovery terminal, comprising:
- a processor configured to:
- search for a recovery candidate corresponding to an interrupted connection, wherein the recovery candidate comprises connection information and a recovery identifier used to identify the connection information;
- use one found recovery candidate as a first recovery candidate, wherein the first recovery candidate comprises a first recovery identifier and first connection information;
- send a negotiation request to a second terminal, wherein the negotiation request comprises the first recovery identifier of the selected first recovery candidate;
- receive a matching success message returned by the second terminal, wherein the matching success message is used to indicate that the second terminal finds a second recovery candidate that has a same recovery identifier as the first recovery candidate;
- and
- transmit data to the second terminal according to the first connection information.
A connection recovery system, comprising:
- a first terminal;
- and
- a second terminal,
- wherein the first terminal is configured to:
- search for a recovery candidate corresponding to an interrupted connection, wherein the recovery candidate comprises connection information and a recovery identifier used to identify the connection information;
- select one found recovery candidate as a first recovery candidate, wherein the first recovery candidate comprises a first recovery identifier and first connection information;
- and
- send a negotiation request to the second terminal, wherein the negotiation request comprises the first recovery identifier of the selected first recovery candidate, wherein the second terminal is configured to:
- search for a second recovery candidate that has a same recovery identifier as the first recovery candidate;
- and
- return a matching success message to the first terminal, and
- wherein the first terminal and the second terminal transmit data to each other according to the first connection information and second connection information respectively.
