Description
Technical Field
The present invention relates to the field of communications technologies, and in particular, to a data transmission method and a communications device.
Background
With the development of communication technology and the advancement of technology, the demand of users for communication is higher and lower, and the demand is not satisfied with the current situation. Compared with 4G (4th-Generation, fifth Generation mobile communication technology) terminal equipment, 5G (5th-Generation, fifth Generation mobile communication technology) terminal equipment can further meet the requirements of users to a great extent in order to meet the requirements of various application scenarios, and the flow and the rate required by the users are ensured. The 5G terminal equipment, especially millimeter wave, has the characteristics of larger radio frequency working bandwidth, higher working frequency band, high-speed transmission, low time delay and the like. However, since the 5G terminal device has a large operating bandwidth and a high operating frequency band, the loss of the corresponding wireless signal in the space is greatly increased, and the 5G terminal device has to transmit a signal with higher power to ensure normal operation, which results in serious power consumption.
Based on the existing 4G terminal device, if the terminal device needs to keep smooth connection with a network device such as a base station, information transmission, including uplink and downlink, needs to be performed. According to the power consumption measurement result in the existing network, the terminal device needs to monitor the paging message once every 1024 milliseconds ms (paging cycle configured by the network) in the downlink state in the idle standby state, the working time of a baseband chip for monitoring the paging message each time is about 28ms, the average current is about 100mA, the standby current when the paging message is not monitored is only about 1mA, and the probability of monitoring the paging message is low, namely although the time for monitoring the paging message only accounts for 8/1024 of the total standby time, the power consumption accounts for about 70% of the total standby power consumption; in the uplink state, high power is needed to transmit the synchronization signal, and the terminal consumes more power without any use.
Further, for 5G terminal devices, especially terminal devices that can access a network by using millimeter waves with huge power consumption, if there is no data transmission requirement, for example, in an idle standby state, monitoring a paging message and sending an uplink synchronization signal through a millimeter wave spatial link to maintain connection with the network side, a large amount of useless power consumption may be caused, and the standby time of the terminal device may be affected.

Detailed Description
In order to more clearly illustrate the technical solutions of the embodiments of the present invention, the drawings required to be used in the embodiments of the present invention will be briefly described below, and it is obvious that the drawings in the following description are only some embodiments of the present invention, and it is obvious for those skilled in the art to obtain other drawings based on these drawings without inventive labor.
It is first noted that the communication device in the embodiment of the present invention may be a terminal device, such as a wearable device, a mobile phone, or a network device, such as a base station. Correspondingly, the communication opposite end of the communication device is a network device or a terminal device.
Specifically, the terminal device in the embodiment of the present invention may access the network by using waves of at least two frequencies. For example, as shown in fig. 1, a terminal device, that is, a mobile phone 1, may be connected to a network Internet through a millimeter wave, and perform data transmission on a spatial link (i.e., a wireless communication spatial link) a established between the terminal device and an NR (New Radio ) Baseband (Baseband)2, or may be connected to the Internet through a non-millimeter wave, where the non-millimeter wave may correspond to a 2G, 3G, 4G, and/or sub-6G mobile network, and perform data transmission on a spatial link b established between the terminal device and a corresponding Baseband 3, where a frequency of the millimeter wave is higher than a frequency of the non-millimeter wave, and when data is transmitted by using the millimeter wave, the terminal device has a higher transmission rate, but higher power consumption. Further, according to the requirements of an actual scene, that is, the requirements of accessing the network by using the millimeter wave, data transmission on the spatial link a may be selected, where the actual scene mainly includes, but is not limited to, a scene requiring large data to be uploaded or downloaded, a scene requiring high speed and low delay, and the like. The mobile phone 1 in the standby state can detect whether the requirement of accessing the network by using the millimeter wave exists through the spatial link b in any scene, thereby reducing monitoring and synchronizing base station signals including uplink and downlink by using the millimeter wave under the condition of no data transmission requirement, reducing useless power consumption of a radio frequency module of the mobile phone 1, improving the standby time of the mobile phone 1 and achieving the purpose of saving power.
The data transmission method of the embodiment of the present invention will be described in detail below.
Referring to fig. 2, an embodiment of the present invention provides a data transmission method, which is applied to a communication device, where the communication device may be a terminal device or a network device, and the method includes the following steps:
step 201: access request information is obtained over a second spatial link when there is a need to access the network using waves of the first frequency.
It is noted that this access request information is used to establish a first spatial link corresponding to a wave of a first frequency. The second spatial chain corresponds to waves of a second frequency, the first frequency being higher than the second frequency. The condition for determining the requirement of the wave access network using the first frequency may be preset according to an actual situation, for example, the requirement of the wave access network using the first frequency may be determined in a scenario that large data is required to be uploaded or downloaded, or in a scenario that high speed and low delay are required.
Further optionally, the wave of the first frequency may be a millimeter wave, and the wave of the second frequency may be at least one of the following non-millimeter waves: 2G non-millimeter waves, 3G non-millimeter waves, 4G non-millimeter waves, and sub-6G non-millimeter waves.
Step 202: and establishing a first spatial link with the communication opposite end according to the access request information.
When the communication equipment is terminal equipment, the communication opposite end is network equipment; and when the communication equipment is network equipment, the communication opposite end is terminal equipment. The access request information may include spatial location information of the terminal device, identification ID information of the terminal device, availability of the wave of the first frequency, and the like.
Step 203: data transmission is performed over the first spatial link.
After the data transmission over the first spatial link is finished, in order to avoid information exchange and data transmission by means of the first spatial link when there is no need to access the network by using the wave of the first frequency, and avoid useless power consumption of the terminal device, the first spatial link may be disconnected, and when there is a need to access the network by using the wave of the first frequency, the first spatial link may be reestablished.
The data transmission method of the embodiment of the invention can acquire the access request information through the second spatial link when the requirement of accessing the network by using the wave of the first frequency is available, establish the first spatial link with the opposite communication terminal according to the access request information, and perform data transmission on the first spatial link, so that the communication equipment can perform information interaction by using the spatial link corresponding to the wave of the low frequency to keep smooth communication connection under the condition of accessing the network by using the waves of at least two frequencies, and can establish the spatial link corresponding to the wave of the high frequency to perform data transmission when the requirement of accessing the network by using the wave of the high frequency is available, thereby avoiding performing information interaction and data transmission by using the spatial link corresponding to the wave of the high frequency when the requirement of accessing the network by using the wave of the high frequency is not available, and further reducing useless power consumption of corresponding terminal equipment, the standby time of the terminal equipment is improved, and the purpose of saving electricity is achieved.
In the embodiment of the present invention, if the communication device is a terminal device and the communication peer is a network device, the access request information may be acquired by the terminal device during a downlink monitoring process of the terminal device (for example, the terminal device in a standby state). Specifically, the process of the terminal device obtaining the access request information through the second spatial link may be:
the terminal equipment monitors the paging message on the second space link;
wherein the paging message includes the access request information.
Therefore, the paging message is monitored on the second spatial link instead of the paging message monitored through the wave of the first frequency, and compared with the paging message monitored through the wave of the first frequency, the method has the advantages that useless power consumption of the terminal equipment in the downlink monitoring process is reduced, the standby time of the terminal equipment is prolonged, and the purpose of saving electricity is achieved.
In the embodiment of the present invention, if the communication device is a network device and the communication peer is a terminal device, the access request information may be obtained by the network device during the uplink synchronization process of the terminal device. Specifically, the process of the network device acquiring the access request information through the second spatial link may be:
the network device receives a synchronization signal on a second spatial link;
wherein the synchronization signal includes the access request information.
Therefore, the terminal equipment can transmit the synchronous signal through the wave of the second frequency instead of receiving the synchronous signal through the wave of the first frequency, and compared with the method for transmitting the synchronous signal through the wave of the first frequency, the method reduces useless power consumption in the uplink synchronization process, improves the standby time length and achieves the purpose of saving power.
In this embodiment of the present invention, the process of establishing, by the communication device, the first spatial link with the communication peer according to the access request information may be:
the communication equipment sends a link establishment request message to a communication opposite end according to the access request message;
the communication equipment receives a link establishment response message sent by a communication opposite terminal;
the communication equipment establishes a first space link according to the link establishment response message.
The link establishment request message may include information such as spatial location information of the terminal device, ID information of the terminal device, and availability of the wave of the first frequency. After receiving the link establishment request message, the correspondent node may send a link establishment response message to the communication device if the correspondent node agrees to establish the first spatial link. In this way, by means of the message interaction process, establishment of the first spatial link between the communication device and the correspondent node can be achieved.
In the embodiment of the invention, in order to further avoid useless power consumption of the terminal equipment, the first spatial link can be disconnected before the access request information is acquired through the second spatial link, so that information interaction and data transmission can be avoided by the first spatial link when the wave utilizing the first frequency is not required to access the network. Specifically, before step 201, the data transmission method may further include:
the communication equipment sends a link disconnection request message to a communication opposite terminal;
the communication equipment receives a link disconnection response message sent by a communication opposite end;
and the communication equipment disconnects the first space link with the communication opposite end according to the link disconnection response message.
The link disconnection request message may include information such as spatial location information of the terminal device, ID information of the terminal device, and availability of the wave of the first frequency. The link down request message may be transmitted over the first spatial link, or may be transmitted over the first spatial link. After receiving the link disconnection request message, the correspondent node may send a link disconnection response message to the communication device if the first spatial link is agreed to be disconnected. In this way, by means of the message interaction process, disconnection of the first spatial link between the communication device and the correspondent node can be achieved.
The following describes in detail a data transmission process according to an embodiment of the present invention with reference to fig. 1 and fig. 3 by taking a downlink listening process as an example.
In the embodiment of the present invention, referring to fig. 1, a terminal device takes a mobile phone 1 as an example, where the mobile phone 1 may be connected to the Internet through millimeter waves to perform data transmission on a spatial link a established between the mobile phone 1 and an NR baseband 2, or may be connected to the Internet through sub-6G non-millimeter waves to perform data transmission on a spatial link b established between the mobile phone 1 and a corresponding baseband 3, where the frequency of the millimeter waves is higher than that of the sub-6G non-millimeter waves, and when data is transmitted by using millimeter waves, the transmission rate is higher, but the power consumption is larger. Specifically, referring to fig. 3, the data transmission process according to the embodiment of the present invention may include the following steps:
step 31: when the requirement of accessing the network by using the millimeter wave is not available, such as in a standby state, the mobile phone 1 sends a link disconnection request message to the base station; the link disconnection request message may be sent through a spatial link a or a spatial link b, the link disconnection request message may be generated by an encoder in the mobile phone 1 and sent to the base station after being modulated, and the link disconnection request message may include information such as spatial position information of the mobile phone 1, ID information of the mobile phone 1, availability of millimeter waves, and the like;
it should be noted that, after receiving the link disconnection request message, the base station may demodulate the link disconnection request message, and if the spatial link a is agreed to be disconnected, send a link disconnection response message to the mobile phone 1, and add a paging message corresponding to the mobile phone 1 on the spatial link b; when the requirement of utilizing the millimeter wave access network exists, the millimeter wave access request information is included in the paging message.
Step 32: the mobile phone 1 receives the link disconnection response message, disconnects the spatial link a after receiving the link disconnection response message, and monitors the paging message on the spatial link b to keep normal registration and connection to the network;
step 33: the mobile phone 1 judges whether the monitored paging message includes millimeter wave access request information;
step 34: if the monitored paging message includes millimeter wave access request information, the mobile phone 1 sends a link establishment request message to the base station according to the millimeter wave access request information, otherwise, the paging message is monitored continuously; the link establishment request message may include information such as spatial location information of the mobile phone 1, ID information of the mobile phone 1, and availability of millimeter waves;
it should be noted that, after receiving the link establishment request message, the base station may demodulate the link establishment request message, and if the spatial link a is agreed to be established, send a link establishment response message to the mobile phone 1.
Step 35: the mobile phone 1 receives the link establishment response message, establishes a spatial link a after receiving the link establishment response message, and performs data transmission on the spatial link a;
step 36: the mobile phone 1 judges whether the data transmission is finished; if not, continuing to transmit data on the spatial link a; otherwise, sending a link disconnection request message to the base station to disconnect the spatial link a.
It can be understood that, through the above data transmission process, millimeter wave monitoring can be performed in a non-millimeter wave working state, that is, when a millimeter wave is not required to access a network, the spatial link a is disconnected, so that power consumption in a millimeter wave standby state is reduced, the standby time of the mobile phone 1 is improved, and the purpose of saving power is achieved.
