Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
In a satellite mobile communication system, due to the large coverage area of a cell, the number of users needing service in the cell is large, and radio resources are very limited. In order to effectively improve the utilization rate of the radio resources of the system, a method of sharing the radio resources by using different logical channels is generally adopted. For example, the DTCH channel and the DACCH channel share the same frequency and time resources, and the DACCH channel occupies the DTCH channel in a preemptive manner, that is, when the system has signaling to send, the sending of the DTCH channel is suspended, and the DACCH channel is sent instead.
In the process of sending data between the base station and the terminal, the network side can monitor the time offset information and the frequency offset information of the terminal, and when the time offset information and the frequency offset information of the terminal need to be adjusted, the time offset and the frequency offset of the terminal are adjusted through the DACCH channel, but due to time division multiplexing of the DACCH channel and the DTCH channel, voice packets can be lost, and user perception is affected.
In view of this, embodiments of the present application provide a time-frequency adjustment method and apparatus, when a time frequency of a terminal needs to be adjusted, by using a logical channel that can be frequency-division multiplexed with a DACH channel to transmit adjustment information and adjusting the terminal, two channels can transmit data simultaneously, so as to reduce loss of a voice packet and improve user perception.
It is to be understood that, in the following description, terms such as "first," "second," and the like are used for descriptive purposes only and not for indicating or implying relative importance, nor for indicating or implying order.
Fig. 1 is a flowchart of a method for time-frequency adjustment according to an embodiment of the present application, where an execution subject of the method shown in fig. 1 may be, but is not limited to, a network device, such as a base station, and as shown in fig. 1, the method includes:
s101: and the network side equipment acquires the time frequency offset information of the terminal.
S102: and judging whether time-frequency adjustment needs to be carried out on the terminal according to the time-frequency offset information of the terminal, if so, executing S103, and if not, executing S104.
S103: and if the time-frequency adjustment of the terminal is determined to be needed, performing the time-frequency adjustment of the terminal by using a first logic channel, wherein the first logic channel is in frequency division multiplexing with a special service channel.
S104: and if the time-frequency adjustment is not needed to be carried out on the terminal, discarding the time-frequency offset information.
Specifically, in the embodiment of the present application, a Slow Associated Control Channel (SACCH) may be referred to as a "first logical Channel", and a DACCH may be referred to as a "second logical Channel".
The DTCH channel is mainly used for transmitting voice data, the DACCH channel is mainly used for transmitting Signaling Radio Bearer (SRB) signaling messages of users, and the SACCH channel is mainly used for transmitting measurement reports, cell selection, and power control messages.
It should be noted that, in the communication protocol, the SACCH channel is mainly used for transmitting some slow Radio Resource Control (RRC) messages, such as measurement reports, and the contents of these messages are relatively small and are not sent frequently.
Moreover, the coding mode of the SACCH channel is special, and the carried signaling data is 84 bits. The specific coding mode is as follows: firstly, after 16-bit CRC coding, 100-bit output bits { u (0), …, u (99) } are obtained, then, 200-bit coded output bits { c (0), …, c (199) } are obtained through tail-biting convolutional coding with 1/2 code rate, then, the 200 channel coded output bits are firstly mapped into a matrix of 10 x 20, then, pseudo-random scrambling of matrix columns is carried out, and then, the matrix columns are divided into 20 10-bit blocks in a column mode to be read out and multiplexed with 20 continuous DTCHs for transmission.
Specifically, the performing, by the network side device, time-frequency adjustment on the terminal by using the first logical channel includes:
and when determining that no first data needs to be sent, sending the time-frequency adjustment information to the terminal through the first logic channel, and performing time-frequency adjustment on the terminal.
Note that the "first data" may be understood as DACCH data.
In the embodiment of the application, if no DACCH data needs to be sent, the time-frequency adjustment information is sent to the terminal through the SACCH channel, and the time-frequency adjustment is carried out on the terminal.
Further, the method also includes: and when the network side equipment determines that the first data needs to be sent, sending the time-frequency adjustment information to the terminal through a second logic channel for sending the first data, and performing time-frequency adjustment on the terminal.
Wherein the second logical channel is time division multiplexed with a dedicated traffic channel.
Specifically, if it is determined that the DACCH data needs to be transmitted, the time-frequency adjustment information is transmitted to the terminal through the DACCH channel, and the time-frequency adjustment is performed on the terminal.
In the embodiment of the application, whether the DACCH data needs to be sent or not needs to be judged, but whether the DACCH data needs to be sent or not is not judged in the prior art, and the adjustment information is transmitted by using the SACCH channel, so that the data can be transmitted simultaneously with the DTCH channel, the loss of data packets is reduced, and the user perception is improved.
Further, in this embodiment of the present application, the time frequency offset information may include a time offset value and a frequency offset value.
In one possible implementation, the time-frequency adjustment may be performed according to a time offset value and a frequency offset value.
Specifically, the network side device determines that the time frequency adjustment needs to be performed on the terminal if it determines that the time offset value is greater than the threshold of the time offset value and/or the frequency offset value is greater than the threshold of the frequency offset value.
It will be appreciated that the threshold values for the time offset values and the frequency offset values are predetermined.
In this embodiment, the first logical channel includes a slow associated control channel SACCH channel.
Furthermore, in the embodiment of the present application, when determining that the time-frequency adjustment needs to be performed on the terminal, the network side may send a control message carrying the time-frequency adjustment information to the terminal through the SACCH channel, and perform the time-frequency adjustment on the terminal.
Specifically, in the embodiment of the present application, when the control message is sent to the terminal using the SACCH channel, in the message content of the control message, in order to match the channel capacity of the SACCH, the message content is reduced as much as possible. The SACCH channel is multiplexed with the DTCH channel, and the adjustment information is transmitted to the terminal on the basis of not occupying voice resources.
In the prior art, in order to achieve the purpose of time/frequency adjustment, although the time-frequency adjustment is also performed on the terminal through the control message, the message is sent through the DACCH channel, and the DTCH channel occupies the time of one frame.
Fig. 2 is a flowchart illustrating another time-frequency adjustment method provided in this embodiment, and referring to fig. 2, the flowchart may be divided into four parts, ABCD.
Wherein, A: and judging whether the last time frequency adjusting process is finished or not. In the embodiment of the application, when the time-frequency adjustment is finished last time, the network side time and frequency adjustment limit flag bit (TFAdjust _ Pro) is 0, and when the flag bit is 0, the time-frequency adjustment can be performed this time.
B: and judging whether time-frequency adjustment needs to be carried out on the terminal.
In the embodiment of the application, the base station may measure a time offset value (Toffset) and a frequency offset value (FOffset) of the reported terminal, and determine whether the Toffset is greater than a threshold of the time offset value or whether the FOffset is greater than a threshold of the frequency offset value.
C: when the time-frequency adjustment is needed to be carried out on the terminal, if DACCH data needs to be sent, the DACCH channel is preferentially used, and the time and frequency adjustment information is sent to the terminal.
In the embodiment of the application, before performing time-frequency adjustment, whether TFAdjust _ Pro is 0 or not may be determined, if TFAdjust _ Pro is 0, adjustment may be triggered, and if TFAdjust _ Pro is not 0, it is determined that the previous adjustment process has not been finished, and adjustment is not performed this time.
D: and if no DACCH data needs to be transmitted, using the SACCH channel to transmit the time and frequency adjustment information to the terminal.
