Detailed Description
In order to make the objects, technical solutions and advantages of the present application more apparent, specific embodiments of the present application will be described in detail with reference to the accompanying drawings. It is to be understood that the specific embodiments described herein are merely illustrative of the application and are not limiting of the application. It should be further noted that, for the convenience of description, only some but not all of the relevant portions of the present application are shown in the drawings. Before discussing exemplary embodiments in more detail, it should be noted that some exemplary embodiments are described as processes or methods depicted as flowcharts. Although a flowchart may describe the operations (or steps) as a sequential process, many of the operations can be performed in parallel, concurrently or simultaneously. In addition, the order of the operations may be re-arranged. The process may be terminated when its operations are completed, but may have additional steps not included in the figure. The processes may correspond to methods, functions, procedures, subroutines, and the like.
Fig. 1 is a flowchart of a method for controlling random access according to an embodiment of the present application, where the method of the present embodiment may be performed by a control apparatus for random access, and the apparatus may be implemented by hardware and/or software, and the apparatus may be disposed inside a mobile terminal as a part of the mobile terminal. The mobile terminal provided by the embodiment of the application includes but is not limited to a mobile phone and other devices.
As shown in fig. 1, the method for controlling random access provided in this embodiment includes the following steps:
The area where the terminal is located in this embodiment may be identified by a Cell Identity (CID) or a Location Area Code (LAC) where the terminal is currently located.
Random access is a necessary process for establishing a radio link between User Equipment (UE) and a network, and data interoperation between the UE and a base station can be performed only after random access is completed.
In the prior art, when a mobile terminal such as a mobile phone performs GSM random access, the used transmission power complies with the available maximum transmission power ms _ txpwr _ max _ cch configured by the network. The ms _ txpwr _ max _ cch configured by some base stations is not a preset maximum transmission power level, so that the maximum power transmission is not adopted when the mobile phone performs GSM random access. If the antenna performance and the signal environment of the mobile phone are not good, the random access will fail, and the normal communication will not be possible. In the prior art, after a mobile phone initiates a random access request in a cell, if the random access request fails, the cell is directly switched to initiate the random access request again, and if no suitable cell exists, the random access cannot be successfully performed. In this embodiment, an access result of terminal random access is detected, after a random access failure is detected, the maximum transmission power that can be used is increased, and random access is performed again by using the increased maximum transmission power, so that the problem of random access failure due to insufficient transmission power can be avoided.
Alternatively, a random access failure event may be considered to be triggered upon detection of a T3126 timeout. The terminal can send a channel request message to the network through the random access channel, starts a T3120 timer, repeatedly sends the channel request message for the maximum allowed times, starts the T3126 timer, waits for a period of time and allows the network to give up, and when the T3126 time out, the random access can be considered to fail.
This step 101 may further comprise: detecting a random access request of the terminal in the current area, judging whether the random access request fails, and if the random access request fails, executing step 102.
And 102, acquiring the maximum transmitting power which can be used when the terminal is randomly accessed.
If the current random access fails, the available maximum transmission power ms _ txpwr _ max _ cch used in the random access is obtained, that is, the current available maximum transmission power.
And 103, increasing the usable maximum transmitting power according to a set adjusting rule, and performing random access again by using the increased usable maximum transmitting power.
And increasing the available maximum transmitting power of the terminal in the current region according to the set adjustment rule, and performing random access again in the current region by using the increased available maximum transmitting power.
And step 104, judging whether the random access stopping condition is met currently, if not, executing the steps 101 to 103 in a circulating way, and if so, ending the process.
If the random access stopping condition is detected to be met currently, stopping performing random access again; and if the random access stopping condition is detected not to be met currently, returning to execute the step 101 to the step 103.
In some embodiments, this step 104 may include: and judging whether the current access is successful at any time, and if not, circularly executing the step 101 to the step 103. If the access is successful, the flow is ended.
In some embodiments, this step 104 may include: judging whether the available maximum transmitting power reaches a preset limit transmitting power grade or whether the current access time reaches a set time length, if the available maximum transmitting power does not reach the preset limit transmitting power grade and the access time does not reach the set time length, circularly executing the step 101 to the step 103, wherein the preset limit transmitting power grade is greater than the preset maximum transmitting power grade. If the usable maximum transmitting power reaches the preset limit transmitting power level or the random access time length reaches the set time length, the random access in the current area is determined to be completely failed, and the cell can be selected again.
The preset maximum transmission power level is the maximum transmission power preset by a system (base station) and capable of ensuring that the performance of the terminal is in a better state, and the preset limit transmission power level is the maximum transmission power which can be borne by the terminal. Illustratively, the preset maximum transmit power level is 30 and the preset maximum transmit power level is 35.
And step 105, ending.
Further, the method can also comprise the following steps: and if the change of the area where the terminal is located is detected, restoring the usable maximum transmitting power to be set as the default transmitting power level of the system.
Optionally, if it is detected that the area where the terminal is located changes, the setting of the available maximum transmission power restoration to the default transmission power level includes: and if the change of the cell number CID or the change of the location area code LAC of the area where the terminal is located is detected, the usable maximum transmitting power is restored and set as the default transmitting power level of the system.
In the method for controlling random access provided in this embodiment, when it is detected that random access of the terminal in the current area fails, the maximum transmission power available for random access of the terminal is obtained, the maximum transmission power available for random access of the terminal is increased according to a set adjustment rule, and random access is performed again by using the increased maximum transmission power available until a random access stop condition is satisfied. The method and the device have the advantages that the usable maximum transmitting power is increased when the random access is failed by using the usable maximum transmitting power configured on the network side, and the random access is performed again by using the increased usable transmitting power, so that the success rate of the random access of the terminal is improved, and the problem that the random access is failed directly when the antenna performance of the terminal or the signal of the environment where the terminal is located is poor due to the fact that the maximum transmitting power is not adopted in the prior art is solved.
Fig. 2 is a flowchart of another random access control method according to an embodiment of the present application. As shown in fig. 2, the method provided by this embodiment includes the following steps:
And step 204, increasing the usable maximum transmitting power to the sum of the preset maximum transmitting power grade and the set increment function value.
If the usable maximum transmitting power is the preset maximum transmitting power level, the usable maximum transmitting power is increased to the preset maximum transmitting power level and a set increment function value is added, and the increased usable maximum transmitting power is used as a new usable maximum transmitting power so as to perform random access again by using the new usable maximum transmitting power.
The setting increment function value and the number of increases of the usable maximum transmitting power may be in direct proportion, and the direct proportion means that the larger the number of increases, the larger the setting increment function value is. Optionally, the set increment function is an initial value of 1, and the tolerance is an equal difference function of the set value. The set value may be 1.
For example, the maximum transmission power that can be used initially is 30, the increment function value for the first increase may be 1, the maximum transmission power that can be used after the first increase is 31, the increment function value for the second increase may be 2, the maximum transmission power that can be used after the second increase is 33, the increment function for the third increase may be 3, and the maximum transmission power that can be used after the third increase is 36, which exceeds the preset limit transmission power, the random access is stopped. Further, for example, the set increment function may be a constant, such as 1 or 2.
And step 205, increasing the available maximum transmitting power to a preset maximum transmitting power level.
If the available maximum transmitting power is not the preset maximum transmitting power level, namely is smaller than the preset maximum transmitting power level, the available maximum transmitting power can be increased to the preset maximum transmitting power level, and the increased available maximum transmitting power is used as the new available maximum transmitting power so as to perform random access again by using the new available maximum transmitting power.
This step may include determining whether the cell number CID of the area in which the terminal is located has changed or whether the location area code LAC has changed.
And step 207, performing random access again by using the new increased available maximum transmission power.
If the area where the terminal is located does not change, the random access can be performed again in the area by using the new increased available maximum transmission power.
And step 208, judging whether the random access stopping condition is met currently, if so, ending step 210, and if not, executing step 201.
If the area where the terminal is located is changed, the usable maximum transmitting power recovery of the next random access can be set as the default transmitting power level of the system, so that the random access in the area after the change is performed by using the default transmitting power level of the system.
And step 210, ending.
According to the random access control method provided by the embodiment, after the first random access of the terminal in the current area fails, the usable maximum transmitting power is increased to the preset maximum transmitting power level or the sum of the preset maximum transmitting power level and the set increment function value, and random access is performed again by using the increased usable maximum transmitting power, so that the success rate of random access of the terminal is increased, the problem that the random access fails directly when the antenna performance of the terminal or the signal of the environment where the terminal is located is poor due to the fact that the maximum transmitting power is not adopted in the prior art is solved, and the success rate of random access of the terminal in each area is increased.
