The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are only a part of the embodiments of the present application, 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 application.
The embodiment of the application provides a communication establishing method, a communication establishing device, computer equipment and a readable storage medium.
The communication establishing apparatus may be specifically integrated in an electronic device, and the electronic device may be a terminal, a server, or other devices. The terminal can be a mobile phone, a tablet Computer, an intelligent bluetooth device, a notebook Computer, or a Personal Computer (PC), and the like; the server may be a single server or a server cluster composed of a plurality of servers.
In some embodiments, the communication establishing means may also be integrated in a plurality of electronic devices.
In some embodiments, the server may also be implemented in the form of a terminal.
A communication establishing method provided in a specific implementation manner of an embodiment of the present application may perform the following steps: judging whether the current target transmitting power is larger than the maximum transmitting power of the user equipment or not; monitoring reference signal received power within a first time period if the target transmit power is greater than the maximum transmit power; calculating new target transmitting power in the first time span according to the reference signal receiving power in the first time span; judging whether the new target transmitting power lasts for a second time length and is not greater than the maximum transmitting power; and if the new target transmitting power lasts for a second time length not greater than the maximum transmitting power, sending a communication establishment request to the base station by using the new target transmitting power until receiving feedback information of the base station or until exceeding the maximum sending times.
The following are detailed below. The numbers in the following examples are not intended to limit the order of preference of the examples.
In this embodiment, a communication establishment method is provided, as shown in fig. 1, a specific flow of the communication establishment method may be as follows 110 to 150:
110. and judging whether the current target transmitting power is greater than the maximum transmitting power of the user equipment or not, if so, executing the step 120.
The target transmission power is a power at which the base station can successfully receive the communication establishment request. The target transmitting power is obtained by adding the target receiving power of the base station and the path loss power; wherein, the target receiving power of the base station is fixed and unchanged, and the path loss power is related to the network environment where the user equipment is currently located.
The communication establishment request is a request sent to the base station by the user equipment for establishing a communication relationship with the base station.
If the current target transmission power is greater than the maximum transmission power of the ue, it indicates that, for the current situation, even if the ue sends the communication establishment request with the maximum transmission power, the base station still cannot successfully receive the communication establishment request, then step 120 is performed.
Optionally, in a specific implementation manner, after the step 110, the embodiment of the present application may further include the following steps a1 to A3:
a1, if the target transmitting power is not larger than the maximum transmitting power, acquiring the last transmitting power of the user equipment, and recording as historical transmitting power.
And A2, calculating the power sum of the historical transmission power and the transmission power increment.
And A3, sending a communication establishment request to the base station with the power sum.
Alternatively, the above steps a1 to A3 may be performed in a loop, for example, when the ue transmits the Random Access Preamble for the first time, the TRANSMISSION time count Preamble _ TRANSMISSION _ COUNTER and the TRANSMISSION POWER boosting time count Preamble _ POWER _ RAMPING _ COUNTER may both be set to 1, and the ue attempts to transmit the Random Access Preamble to the bs for the first time.
If the user equipment does not receive the feedback information Random Access Response message returned by the base station within the preset time period, the user equipment sets the sending times PREAMBLE _ TRANSMISSION _ COUNTER and the times PREAMBLE _ POWER _ RAMPING _ COUNTER for increasing the transmitting POWER to 2, and tries to send a communication establishment request Random Access PREAMBLE for the second time. And compared with the first time of sending the communication establishment request Random Access Preamble, the second time of sending the communication establishment request Random Access Preamble has the transmission power increased by the transmission power increment powerRampingStep.
……
The above process will not cycle continuously until the sending times reaches the maximum sending times preambleTransMax, or receive the feedback information Random Access Response message returned by the base station in the preset time period.
Optionally, in the above embodiment, if the target transmission power is less than or equal to the maximum transmission power, it indicates that the ue has a greater probability of establishing communication with the base station before reaching the maximum transmission power. Therefore, it is possible to acquire the historical transmission power of the user equipment at the last time of transmitting the communication establishment request, and increase the transmission power increment on the basis of the historical transmission power to obtain a power sum, and transmit the communication establishment request to the base station at the power sum. By attempting to establish communication with the base station by incrementally increasing the transmit power increment, the power consumption of the user equipment can be reduced as much as possible.
It should be understood that, in the case that the target transmission power is not greater than the maximum transmission power, in addition to performing step a1 to step A3, a current value of the target transmission power may be directly obtained, and a communication establishment request may be sent to the base station at a power corresponding to the value, so that the communication establishment between the user equipment and the base station may be more efficiently achieved.
For convenience of description, the target receiving power of the base station is set to P without setting the communication relationship that the ue desires to establish with the base station as 5G communicationPRACH,target,f,cIndicating the power lost on the way as PLb,f,cIndicates that the target transmission power is PPRACH,target,f,c+PLb,f,c(ii) a Maximum transmit power of user equipment in PCMAX,f,c(i) Represents; the communication establishment request is a Random Access Preamble message.
120. The reference signal received power is monitored for a first length of time.
The first time length is a preset time length, and the specific time length value is not to be understood as a limitation to the application; alternatively, the first length of time may be recorded by a T1 timer.
The Reference Signal Receiving Power (RSRP) may be measured by the ue. Since RSRP is strongly related to the network environment, the embodiments of the present application may be applied in a scenario where the network environment changes rapidly, for example, in a high-speed mobile scenario.
130. And calculating new target transmitting power in the first time length according to the reference signal receiving power in the first time length.
Optionally, referring to fig. 2, in an embodiment, the step 130 may specifically include the following steps 131 to 132:
131. and calculating the path loss power according to the transmitting power of the base station and the receiving power of the reference signal.
Optionally, a difference between the base station transmission power and the reference signal received power may be calculated, where the difference is the path loss power.
Can be according to the formula PLb,f,cCalculating path loss power PL by using the reference Signal Power-RSRPb,f,cWherein, the referenceSignalPower is the base station transmission power, and the referenceSignalPower is usually fixed and unchanged.
132. And calculating new target transmitting power according to the path loss power and the target receiving power of the base station.
Optionally, a sum of the path loss power and the target received power may be calculated, the sum being the new target transmit power.
Can be according to the formula PHair-like device＝PPRACH,target,f,c+PLb,f,cCalculating a new target transmit power PHair-like device。
In the above embodiment, the path loss power may be calculated according to the base station transmit power and the reference signal received power, and then the path loss power and the target received power may be used to calculate a new target transmit power. The path loss power is a difference value obtained by subtracting the transmitting power of the base station from the receiving power of the reference signal; the new target transmitting power is the sum of the path loss power and the target receiving power of the base station.
140. And judging whether the new target transmitting power lasts for a second time length not greater than the maximum transmitting power, if so, executing step 150.
The second time length is a preset time length, the second time length is smaller than or equal to the first time length, and the specific value of the time length is not to be understood as a limitation to the application; alternatively, the second length of time may be recorded by a T2 timer.
If the new target transmission power is less than or equal to the maximum transmission power and the state of less than or equal to the maximum transmission power is kept for the second time length, then the following is stated: step 150 may be performed because there is a high probability that the user equipment will successfully establish communication with the base station by adjusting the power at which the user equipment sends the communication establishment request.
Optionally, in a specific embodiment, if the new target transmission power does not last for the second time duration and is not greater than the maximum transmission power, the communication establishment request procedure is stopped.
The new target transmission power does not last for a second time length not greater than the maximum transmission power, which has two cases: firstly, the new target transmitting power is larger than the maximum transmitting power in a first time length; and secondly, the new target transmission power has the condition that the new target transmission power is less than or equal to the maximum transmission power within the first time length, but the duration of the condition does not exceed the second time length.
In either case, the communication establishment process cannot be implemented by the ue, that is, the ue cannot be received by the base station even though sending the communication establishment request to the base station with the maximum transmit power, so that the communication establishment request process can be stopped, thereby saving the power of the ue.
150. And sending a communication establishment request to the base station at the new target transmitting power until the feedback information of the base station is received or the maximum transmitting times is exceeded.
Continuing with the above example, the feedback information of the base station may be denoted as Random Access Response; the maximum number of transmissions may be denoted as preambleTransMax. If the user equipment receives the feedback information Random Access Response of the base station, it may indicate that the communication is successfully established, that is, it may be determined that the RACH procedure is successfully established. If the number of times that the user equipment sends the communication establishment request exceeds the maximum sending number of times, the communication establishment still cannot be successfully established, the communication establishment is failed, and the RACH procedure establishment failure can be determined.
The method provided by the embodiment of the application can firstly judge whether the current target transmitting power is larger than the maximum transmitting power of the user equipment; if the target transmitting power is larger than the maximum transmitting power, the reference signal receiving power is monitored in the first time length, and the target transmitting power in the first time length is calculated according to the reference signal receiving power in the first time length. Then judging whether the target transmitting power in the first time length can be not more than the maximum transmitting power or not, and keeping the state of not more than the maximum transmitting power for a second time length; if so, the user equipment sends a communication establishment request to the base station at the target transmission power which is not more than the maximum transmission power so as to realize the establishment of the communication. In the embodiment of the application, the target transmitting power is compared with the maximum transmitting power, and when the current target transmitting power is greater than the maximum transmitting power, the new target transmitting power within the first time length is obtained, and whether the new target transmitting power is continuously less than or equal to the maximum transmitting power is judged. And sending the communication establishment request to the base station by the target transmitting power under the condition that the target transmitting power is less than or equal to the maximum transmitting power, namely the scheme can send the communication establishment request under the conditions that the network environment is good and the communication is established with the base station with higher success probability, thereby effectively reducing the electric quantity consumption of the user equipment.
Optionally, in a specific implementation manner, before step 110, the method provided in the embodiment of the present application may further include: determining that the number of transmissions of the communication establishment request does not exceed the maximum number of transmissions.
The number of times of TRANSMISSION of the communication establishment request can be represented by PREAMBLE _ transition _ COUNTER
In the foregoing embodiment, before determining whether the target transmission power is greater than the maximum transmission power, it may be determined that the number of times of sending the communication establishment request of the ue does not exceed the maximum number of times of sending, and if the number of times of sending has reached or exceeded the maximum number of times of sending, the sending of the communication establishment request may be stopped because the number of times of sending reaches the maximum number of times of sending without comparing the target transmission power with the maximum transmission power. Therefore, the method provided by the application is executed under the condition that the sending times do not exceed the maximum sending times, so that the power consumption of the user equipment can be better saved.
Optionally, in a specific implementation manner, before the step "determining that the number of sending times of the communication establishment request does not exceed the maximum number of sending times", the embodiment of the present application may further include the following steps S1 to S2:
and S1, determining the first transmission power according to the communication parameters.
The mode of determining the transmission power of the communication establishment request according to the communication parameters of the communication is an open loop power control mode.
The communication parameters stored in the user equipment may be obtained from a system message systemlnformationblocktype 1 received from the base station. The communication parameters included in the system message are specifically as follows: preambleReceivedTargetPower, namely the power of Random Access Preamble message expected to be received by the base station; preamble TransMax, which is the maximum number of times that the user equipment tries to send a Random Access Preamble message; the powerRampingstep is the transmission power increment, that is, if the retransmission of the Random Access Preamble message occurs, the power of each retransmission is increased by the step length of the powerRampingstep until the maximum transmission power of the user equipment is finally reached or the number of retransmissions reaches the maximum number of preambleTransMax; the referrencignalpower, i.e. the base station transmission power, may also be represented by SS-pbcblockpower.
And S2, sending a communication establishment request to the base station with the first transmission power, and not receiving feedback information returned by the base station within a preset time period.
In the foregoing embodiment, before determining that the number of times of sending the communication establishment request does not exceed the maximum number of times of sending, first determining first transmit power according to a communication parameter of the user equipment itself, and attempting to send the communication establishment request with the first transmit power, where if no feedback information returned by the base station is received within a preset time period, it indicates that the sending of the communication establishment request with the first transmit power cannot achieve establishment of communication; on the basis, a series of operations such as comparison of the target transmission power and the maximum transmission power can be performed. If the communication establishment is directly and successfully realized when the communication establishment request is sent by the first transmitting power, the operations of comparing the target transmitting power with the maximum transmitting power and the like can be omitted, and the efficiency of establishing the communication is improved.
In order to better implement the method, embodiments of the present application further provide a communication establishing apparatus, which may be specifically integrated in an electronic device, where the electronic device may be a terminal, a server, or the like.
