Detailed Description
Embodiments of the present application will be described in detail below with reference to the accompanying drawings.
Referring to fig. 1, fig. 1 is a flow chart of an information transmission method according to an embodiment of the application. The information transmission method can be particularly applied to the first terminal. In the embodiment of the application, the first terminal performs information transmission with the second terminal through the first wireless connection. Wherein the first wireless connection is a bluetooth connection. The first terminal and the second terminal may be terminal devices with wireless transmission capability, such as mobile phones (e.g. Android mobile phones, iOS mobile phones, etc.), tablet computers, desktop computers, mobile internet devices (Mobile Internet Devices, MID), personal digital assistants (Personal Digital Assistant, PDA), etc. As shown in fig. 1, the information transmission method includes the steps of:
s11, acquiring first information and determining a first time slot number occupied by the first information.
Wherein the first time slot number is a positive number. In the embodiment of the present application, the first timeslot number is the timeslot number actually occupied by the first information. For example, the first number of slots may be 1 or 2.5.
S12, determining a second time slot number according to the first time slot number, and packaging the first information according to the second time slot number to obtain a first packet.
In the embodiment of the present application, the first timeslot number is the actual length of the first information, and the second timeslot number is the timeslot number used by the first terminal to transmit the first information, i.e. the second timeslot number is the timeslot number occupied by the first packet. Wherein the second time slot number is larger than the first time slot number.
Under the bluetooth standard, the transmission timing of a packet is in units of slots (slots), and the packet length is divided into three types of 1 slot, 3 slots, and 5 slots. Thus, in the embodiment of the present application, the second number of slots may be 1, 3 or 5.
For example, when the first number of slots occupied by the first information (i.e., the actual length of the first information) is 2.5 slots, the first terminal may determine the second number of slots as 3 or 5.
In a specific embodiment, after determining the first number of timeslots occupied by the first information, the first terminal may determine whether the first number of timeslots is greater than or equal to 3 and less than 5; if yes, the first terminal can directly determine the second time slot number as 5; if not, the first terminal may determine the second number of timeslots in the following two ways.
As an alternative embodiment, the determining, by the first terminal, the second time slot number according to the first time slot number may specifically include: acquiring an electric quantity value of the first terminal; a second number of time slots is determined based on the power value and the first number of time slots.
Wherein the electrical quantity value may be specifically an electrical quantity percentage.
In a specific embodiment, the determining, by the first terminal, the second time slot number according to the power value and the first time slot number may specifically include: if the electric quantity value of the first terminal is smaller than or equal to the electric quantity threshold value, the first terminal can determine that the number of the second time slots is larger than 3; if the power level of the first terminal is greater than the power level threshold, the first terminal may determine the second slot number as 5.
For example, when the first time slot number is 1.6 and the preset power threshold is 20%, if the power value of the first terminal is less than or equal to 20%, the first terminal may determine the second time slot number as 3; if the power value of the first terminal is greater than 20%, the first terminal may determine the second slot number as 5.
As another alternative embodiment, the determining, by the first terminal, the second time slot number according to the first time slot number may specifically include: determining the number of wireless connections currently established by the first terminal; and determining a second time slot number according to the wireless connection number and the first time slot number.
In a specific embodiment, the determining, by the first terminal, the second time slot number according to the radio connection number and the first time slot number may specifically include: if the number of wireless connections currently established by the first terminal is less than or equal to a first threshold, the first terminal may determine the second time slot number as 3; if the number of wireless connections currently established by the first terminal is greater than the first threshold, the first terminal may determine the second number of timeslots to be 5.
For example, when the first timeslot number is 0.9 and the preset first threshold is 1, if the number of wireless connections currently established by the first terminal is equal to 1, that is, the first terminal only establishes the first wireless connection, the first terminal may determine the second timeslot number as 3; if the number of wireless connections currently established by the first terminal is greater than 1, that is, the first terminal establishes other wireless connections except the first wireless connection, the first terminal may determine the second time slot number as 5.
As yet another alternative embodiment, the determining, by the first terminal, the second time slot number according to the first time slot number may specifically include: acquiring the attribute of information to be transmitted and/or the transmission requirement of the information to be transmitted in the second wireless connection; and determining the second time slot number according to the attribute of the information to be transmitted and/or the transmission requirement of the information to be transmitted.
In an embodiment of the present application, the attribute of the information to be transmitted may include, but is not limited to, a data type, a data size, etc. of the information to be transmitted. The transmission requirement of the information to be transmitted may include, but is not limited to, a transmission time requirement of the information to be transmitted, wherein the transmission time requirement may be a time required for the information to be transmitted to complete in the second wireless connection.
In a specific embodiment, the determining, by the first terminal, the second time slot number according to the attribute of the information to be transmitted and/or the transmission requirement of the information to be transmitted may specifically include: if the transmission time requirement of the information to be transmitted is less than or equal to a first time threshold, the first terminal can determine the second time slot number as 3; if the transmission time requirement of the information to be transmitted is greater than the first time threshold, the first terminal may determine the second time slot number to be 5.
For example, when the first timeslot number is 1 and the preset first time threshold is 2, if the transmission time requirement of the information to be transmitted in the second wireless connection is 1 timeslot, the first terminal may determine the second timeslot number as 3; if the transmission time requirement of the information to be transmitted in the second wireless connection is 4 timeslots, the first terminal may determine the second timeslot number as 5.
In the embodiment of the present application, the first terminal determines a second time slot number according to the first time slot number, and encapsulates the first information according to the second time slot number in order to reserve an idle time slot for other wireless connections established by the first terminal except for the first wireless connection. The idle time slot is a time slot except for the time slot occupied by the first information in the time slots occupied by the first packet, or the idle time slot is a time slot remained after the transmission of the first information in the time slots occupied by the first packet is completed.
S13, determining a sending time slot of the first packet, and sending the first packet to the second terminal according to the sending time slot and the first time slot number through the first wireless connection.
For convenience of description, the transmission time slot, the first time slot number, and the second time slot number are denoted as k, i, and j, respectively.
In the first wireless connection, the first terminal may be a bluetooth master (master) or a bluetooth slave (slave). When the first terminal is a Bluetooth master device, k is an even number; when the first terminal is a bluetooth slave device, k is an odd number.
In the embodiment of the present application, the first terminal transmitting the first packet to the second terminal according to the transmission time slot and the first time slot number through the first wireless connection may specifically include: the first terminal starts to send the first packet to the second terminal at the kth time slot through the first wireless connection, and the first information is sent out from the kth+i time slot.
The packet header of the first packet includes a packet type, which is used to indicate the second time slot number occupied by the first packet. Thus, when the second terminal receives the packet header of the first packet, it knows that this packet occupies a total of several time slots, and that the next several time slots are occupied by the first packet, and the second terminal will not transmit a packet to the first terminal until the time slot occupied by the first packet ends. And the first terminal performs information transmission according to the actual packet length, and the time slot left after the information transmission is completed is the idle time slot reserved by the first terminal for other wireless connection. Since the second terminal does not transmit a packet to the first terminal in an idle slot, the probability of collision of communication signals of the first wireless connection with other wireless connections can be reduced. In the embodiment of the application, the idle time slot is a time slot between the (k+i) th time slot and the (k+j) th time slot, and the length is j-i.
As an alternative embodiment, the first terminal may transmit information with the second terminal through the second wireless connection in an idle time slot between the k+i time slot and the k+j time slot. In this embodiment, the second wireless connection may be, for example, a Wi-Fi connection.
As another alternative embodiment, the first terminal may transmit information with the third terminal through the second wireless connection in an idle time slot between the k+i time slot and the k+j time slot. In this embodiment, the second wireless connection may be a bluetooth connection or a Wi-Fi connection.
Referring to fig. 2, fig. 2 schematically illustrates the use of idle slots. In fig. 2, the one terminal is a bluetooth slave device, and the second terminal is a bluetooth master device. In the k-1 time slot, the second terminal transmits a second packet with a length of 1 time slot to the first terminal through the first wireless connection, wherein the second packet comprises second information with a length of 0.5 time slot.
When the second packet is received, at the kth time slot, the first terminal starts replying a first packet with a length of 5 to the second terminal through the first wireless connection, wherein the first packet comprises first information with a length of 0.3 time slot. At the k+0.3 time slot, the first terminal has transmitted the first information.
Correspondingly, at the kth slot, the second terminal starts to receive the first packet. At the k+0.3 time slot, the second terminal receives the first information, but 4.7 time slots from the k+0.3 time slot to the k+5 time slot are still occupied by the first packet, and the time slots are idle time slots. Up to the k+5 time slot, the second terminal continues to transmit a third packet with a length of 1 to the first terminal through the first wireless connection, where the third packet includes third information with a length of 0.5 time slot.
And the first terminal may transmit information over other wireless connections in the free time slots between the k+0.3 time slot and the k+5 time slot. As shown in fig. 2, at the k+0.8 time slot, the first terminal may receive a fourth packet of length 3 from the third terminal over the second wireless connection. Wherein the second wireless connection is a Wi-Fi connection. At the k+4 time slot, the first terminal may reply to the third terminal with a fifth packet of length 0.5 over the second wireless connection.
In a specific embodiment, the second terminal may obtain its power value when the first packet is received; if the power value is smaller than the preset power threshold, the second terminal may send a low power notification to the first terminal, so that the first terminal does not reserve an idle slot for other wireless connections when determining the second slot number again.
In the Bluetooth connection, the idle time slot is reserved for other wireless connections to transmit information through long packet short transmission, and the embodiment of the application can reduce the probability of collision of communication signals of a plurality of wireless connections in the same terminal equipment and improve the communication efficiency.
