and receiving feedback sent by the first terminal through the connection corresponding to the connection identifier.
In this embodiment of the present invention, when the second terminal receives the service access request sent by the first terminal through the tunnel, optionally, the following manner may be adopted:

and the second terminal sends a service access response to the first terminal through the tunnel according to the service access request by adopting a communication mode corresponding to the connection mode of the first terminal and the second terminal.
For example, if the first terminal and the second terminal are connected by USB, the first terminal sends a service access request to the second terminal through a tunnel in a USB communication manner, or receives a service access response sent by the second terminal.
In the embodiment of the invention, the service access response can be operations such as returning data, closing connection, refusing connection and the like.
In the scheme, the first terminal and the second terminal communicate through the tunnel, the service access request and the service access response transmitted through the tunnel adopt TCP and/or UDP protocols, the TCP/UDP protocols are common in the communication field, and an open source library, a framework and a program based on the protocols are very common without defining a new protocol, so that the defect of low access service efficiency in the prior art can be overcome.
In the embodiment of the invention, the service layer is separated from the physical communication layer between the two terminals, so that a new protocol does not need to be redefined when the communication mode between the first terminal and the second terminal is changed, for example, when the communication mode between the first terminal and the second terminal is converted from a USB mode to a Bluetooth mode, the new protocol does not need to be redefined.
An embodiment of the present invention further provides an embodiment of accessing a service, which is shown in fig. 3.
Step 300: the first terminal establishes a tunnel capable of communicating with the second terminal.
The second terminal waits for connection or data at the service providing port to provide service, and the first terminal selects an idle TCP service request port which adopts the same protocol as the protocol adopted by the service providing port to listen to or wait for the data.
Step 310: and the tunnel layer of the first terminal sends a service access request to the second terminal through the tunnel, wherein the service access request adopts a TCP and/or UDP protocol.
In this step, data transmitted by the first terminal and the second terminal through the tunnel is encapsulated in a certain specification, such as defining a specification of a data packet in the tunnel, bytes 0 to 3 indicate a length of the whole data packet, bytes 4 to 5 are operation and status identifiers (one bit corresponds to each protocol operation and status, such as 0x01 indicating that a TCP connection is requested to be established, 0x02 indicating that the TCP connection is closed, 0x04 indicating data transmission, 0x08 indicating a connection error, etc.), bytes 6 to 9 indicate a TCP connection identifier for distinguishing from other TCP connection data, bytes 10 to 17 indicate an offset of an ending data counted from the data of the first byte received currently receivable by the current tunnel layer, i.e. a reception sliding window, and byte 18 indicates data sent by the requesting application.
Step 320: and after receiving the service access request, the tunnel layer of the second terminal decapsulates according to the agreed encapsulation specification, and initiates operations to the service layer port, such as establishing a TCP connection, transmitting TCP data, and the like.
Step 330: the second terminal sends a service access response to the first terminal through the tunnel.
The service access response may be packets such as return data, close connection, and reject connection.
And the first terminal and the second terminal continuously carry out interactive communication according to the steps.
It should be noted that the above steps are only a specific case of accessing a service, and according to actual needs, the first terminal may provide multiple service providing ports on one service, or the second terminal has multiple service providing ports to provide services, and the first terminal only needs to open as many TCP service requesting ports according to the above steps to establish one-to-one mapping of ports.

29. The terminal of claim 28, wherein the protocol used by the service providing port is the same as the protocol used by the TCP service request port in the first terminal.
30. The terminal of claim 28, wherein the port number of the service providing port is the same as or different from the port number of the TCP service request port in the first terminal.
31. The terminal according to claim 28, 29 or 30, wherein the receiving unit is further configured to receive an identifier of the TCP connection and/or a port number of the TCP service request port sent by the first terminal.
32. The terminal of claim 28, wherein the protocol used by the service providing port is the same as the protocol used by the UDP service request port in the first terminal.
33. The terminal of claim 28, wherein the port number of the service providing port is the same as or different from the port number of the UDP service request port in the first terminal.
34. The terminal according to claim 28, 32 or 33, wherein the receiving unit is further configured to receive a port number of the UDP service request port sent by the first terminal.
35. The terminal according to claim 28, 32 or 33, wherein the sending unit is further configured to send data carrying the connection identifier to the first terminal;
the receiving unit is further configured to receive feedback sent by the first terminal through a connection corresponding to the connection identifier.
36. The terminal according to claim 28, 32 or 33, wherein the receiving unit receives the service access request sent by the first terminal through the tunnel, and includes:
receiving a service access request sent by the first terminal through the tunnel by adopting a communication mode corresponding to a connection mode of the first terminal and the second terminal;
the sending unit sends a service access response to the first terminal through the tunnel according to the service access request, and the sending unit includes:
and sending a service access response to the first terminal through the tunnel according to the service access request by adopting a communication mode corresponding to the connection mode of the first terminal and the second terminal.
