Detailed Description
In order to make the objects, technical solutions and advantages of the present application more apparent, the present application is described in further detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present application and are not intended to limit the present application.
The cell access method provided by the present application can be applied to the application environment shown in fig. 1. The application environment includes a base station 100 and a mobile terminal 200, and the base station 100 is in communication connection with the mobile terminal 200. The mobile terminal 200 may be, but not limited to, various smart phones, tablet computers, portable wearable devices, and the like. The Base Station may be, but not limited to, a macro Base Station, a micro Base Station, a small Base Station, and other types of Base Station devices, and may be a Base Station (BTS) in Global System for Mobile communication (GSM) or Code Division Multiple Access (CDMA), a Base Station (NodeB) in Wideband Code Division Multiple Access (WCDMA), an evolved Node B (eNB) or eNodeB) in LTE, a relay Station or Access point, a Base Station in a future 5G network, a Customer Premise Equipment (CPE), and the like, and is not limited herein.
In an embodiment, as shown in fig. 2, a cell access method is provided, which is described by taking the application of the method to the mobile terminal in fig. 1 as an example, and includes the following steps:
The first communication environment information represents the communication environment of the mobile terminal when the access fails.
When the mobile terminal needs to register the network, a connection request is sent to the base station of the first cell, and if the response returned by the base station of the first cell is not received after the set time is exceeded, the uplink access failure is determined, namely the network registration failure. The mobile terminal may attempt to re-access, i.e. re-send a connection request to the base station of the first cell. After the mobile terminal sends the connection request of the preset times to the base station of the first cell, the response returned by the base station of the first cell is not received, and then the mobile terminal is determined to fail to access the first cell. The embodiment of the disclosure does not limit the set time and the preset times, and can be set according to actual conditions.
In this case, the mobile terminal acquires the first communication environment information according to the communication environment in which the mobile terminal is located. For example, the mobile terminal detects the signal strength corresponding to the base station of the first cell, detects the geographical location of the mobile terminal, and so on, and obtains the first communication environment information. The embodiment of the present disclosure does not limit the communication environment, and can be set according to actual situations.
The mobile terminal also attempts to access the second cell while acquiring the first communication environment information. Specifically, the mobile terminal detects the signal strength of other cells except the first cell, and takes the cell with the largest signal strength as the second cell. And then, the mobile terminal sends a connection request to the base station of the second cell, and if a response returned by the base station of the second cell is received within the set time, the uplink access is successful, namely the network registration is successful. It can be understood that, in the case of failure in accessing the first cell, attempting to access the second cell can avoid the problem that access to one cell fails and the entire network is no longer accessed.
And the second communication environment information represents the communication environment of the mobile terminal after the preset time.
And the mobile terminal starts timing after the failure of accessing the first cell, and detects the communication environment of the mobile terminal again after the preset time length to obtain the second communication environment information. For example, after 90 seconds, the mobile terminal detects the communication environment and obtains the second communication environment information. The preset duration is not limited, and can be set according to actual conditions.
And after the mobile terminal acquires the second communication environment information, comparing the second communication environment information with the first communication environment information to determine whether the communication environment of the mobile terminal is changed. If the communication environment of the mobile terminal is changed and the change of the communication environment enables the first cell to meet the preset access condition, the mobile terminal sends a connection request to the base station of the first cell again, namely, the mobile terminal tries to access the first cell again. And if the communication environment of the mobile terminal is not changed, determining that the first cell does not meet the preset access condition, and still maintaining the network connection with the second cell.
In the cell access method, the mobile terminal acquires the first communication environment information of the mobile terminal under the condition of failure of accessing the first cell and tries to access the second cell; after the preset time length, acquiring second communication environment information of the mobile terminal; and if the first cell meets the preset access condition according to the first communication environment information and the second communication environment information, re-trying to access the first cell. In the embodiment of the disclosure, after the mobile terminal fails to access the first cell, the mobile terminal tries to access the second cell, so that the problem that the whole network is not accessed any more due to the access failure of one cell can be avoided, and the network registration efficiency can be improved; and the mobile terminal retries to access the first cell after the communication environment changes, so that not only can the network registration efficiency be improved, but also the communication effect can be improved.
In one embodiment, as shown in fig. 3, the first communication environment information includes first signal strength information; the step of determining that the first cell meets the preset access condition according to the first communication environment information and the second communication environment information when the second communication environment information includes the second signal strength information may include:
The Signal Strength information may include at least one of Reference Signal Receiving Power (RSRP), Received Signal Strength Indicator (RSSI), Reference Signal Receiving Quality (RSRQ), and Signal-to-Noise Ratio (SNR).
Comparing the second communication environment information with the first communication environment information to determine whether the first cell satisfies a preset access condition may include: comparing a second signal strength indicated by the second signal strength information with a first signal strength indicated by the first signal strength information; if the second signal strength is greater than the first signal strength, calculating a signal strength difference between the second signal strength and the first signal strength; and calculating the ratio of the signal intensity difference to the first signal intensity to obtain the improvement ratio of the signal intensity.
For example, if the first signal strength is a, the second signal strength is b, and b > a, then the signal strength difference c is calculated as b-a; then, the ratio k1 is calculated to be c/a, and k1 is the rise ratio of the signal strength.
In one embodiment, if the second signal strength is less than or equal to the first signal strength, it is determined that the first cell does not satisfy the preset access condition.
When the mobile terminal compares the second signal strength with the first signal strength, if the second signal strength is less than or equal to the first signal strength, the first cell can be directly determined not to meet the preset access condition, and the improvement proportion of the signal strength does not need to be calculated.
If the signal intensity increasing ratio is larger than the preset ratio, the signal intensity is better and the first cell is more suitable for access after the preset time, so that the first cell is determined to meet the preset access condition. And if the promotion ratio of the signal intensity is smaller than or equal to the preset ratio, determining that the first cell does not meet the preset access condition.
For example, the preset ratio is k0, and if k1 is greater than k0, the first cell is determined to satisfy the preset access condition. If k1 is less than or equal to k0, it is determined that the first cell does not satisfy the preset access condition.
In one embodiment, the preset ratio can be adjusted according to actual conditions. When the improvement ratio of the signal intensity is larger than the preset ratio, the first cell is tried to be accessed again after the first cell is determined to meet the preset access condition, and if the first cell is failed to be accessed again, the preset ratio can be improved, so that the first cell is determined to meet the preset access condition according to the preset ratio at the next time, the probability of successfully accessing the first cell is improved, and the network registration efficiency is improved.
The step of determining that the first cell meets the preset access condition according to the first communication environment information and the second communication environment information determines a signal strength increase ratio according to the first signal strength information and the second signal strength information; and if the promotion ratio of the signal intensity is larger than the preset ratio, determining that the first cell meets the preset access condition. In the embodiment of the disclosure, the mobile terminal judges whether the first cell is suitable for access or not according to the signal strength, the detection mode of the communication environment is simple and easy to implement, and no additional hardware is required.
In one embodiment, as shown in fig. 4, in a case that the first communication environment information includes first relative location information between the mobile terminal and the first cell, and the second communication environment information includes second relative location information between the mobile terminal and the first cell, the determining that the first cell satisfies the preset access condition according to the first communication environment information and the second communication environment information may include:
step 401, determining whether the mobile terminal has displacement according to the first relative position information and the second relative position information.
Wherein the first relative position information comprises a first relative position between the mobile terminal and a base station of the first cell; the second phase position information comprises a second relative position between the mobile terminal and the base station of the first cell.
Comparing the second relative position information with the first relative position information in the process of determining whether the mobile terminal has displacement; and if the second relative position information is not matched with the first relative position information, determining that the mobile terminal has displacement. And if the second phase position information is matched with the first relative position information, determining that the mobile terminal has no displacement.
In one embodiment, the mobile terminal obtains the geographic location of each base station in advance, determines the geographic location of the mobile terminal through a Positioning module such as a GPS (Global Positioning System) when detecting the communication environment, and then determines the relative location between the mobile terminal and the base station of the first cell according to the geographic location of the base station of the first cell and the geographic location of the mobile terminal.
In one embodiment, a mobile terminal acquires the geographic position of each base station in advance; then, the mobile terminal sends a test instruction to the base station of the second cell and receives a feedback instruction of the base station of the second cell; determining the relative position between the mobile terminal and the base station of the second cell according to the sending time of the test instruction, the receiving time of the feedback instruction and the signal propagation speed; then, the mobile terminal determines the relative position between the mobile terminal and the base station of the first cell according to the relative position between the mobile terminal and the base station of the second cell and the relative position between the base station of the first cell and the base station of the second cell. The method for determining the relative position is not limited in the embodiment of the disclosure, and can be set according to actual conditions.
Step 402, if the mobile terminal has displacement and the displacement is greater than a preset length, determining that the first cell meets a preset access condition.
If the mobile terminal has a displacement, the displacement of the mobile terminal is calculated according to a first relative position between the mobile terminal and the base station of the first cell and a second relative position between the mobile terminal and the base station of the first cell. And then, the mobile terminal judges whether the displacement is greater than a preset length. If the displacement is larger than the preset length, determining that the first cell meets the preset access condition; and if the displacement is smaller than the preset length, determining that the first cell does not meet the preset access condition.
In the step of determining that the first cell meets the preset access condition according to the first communication environment information and the second communication environment information, the mobile terminal determines whether the mobile terminal has displacement according to the first relative position information and the second relative position information; and if the mobile terminal has displacement which is greater than the preset length, determining that the first cell meets the preset access condition. In the embodiment of the disclosure, the mobile terminal judges whether the first cell is suitable for access according to the geographic position, the detection mode of the communication environment is simple and easy to implement, and no additional hardware is required.
In an embodiment, as shown in fig. 5, a cell access method is provided, which is described by taking the application of the method to the terminal in fig. 1 as an example, and includes the following steps:
After the failure of accessing the first cell, the mobile terminal sets the first cell as a forbidden access cell, that is, the mobile terminal does not try to access the first cell any more within a preset time length. It can be understood that, within the preset time, the first cell is set as the cell prohibited from being accessed, so that the problem that the mobile terminal falls into the trap cell and cannot find the resident and registered cell of the network-capable cell all the time can be avoided.
In one embodiment, the second signal strength indicated by the second signal strength information is compared with the first signal strength indicated by the first signal strength information; if the second signal strength is greater than the first signal strength, calculating a signal strength difference between the second signal strength and the first signal strength; and calculating the ratio of the signal intensity difference to the first signal intensity to obtain the improvement ratio of the signal intensity.
In one embodiment, if the second signal strength is less than or equal to the first signal strength, it is determined that the first cell does not satisfy the preset access condition.
And 505, determining whether the mobile terminal has displacement according to the first relative position information and the second relative position information.
In one embodiment, the second relative position information is compared with the first relative position information; and if the second relative position information is not matched with the first relative position information, determining that the mobile terminal has displacement.
In one embodiment, the preset access condition may include: the signal intensity is increased by at least one of a ratio larger than a preset ratio and a displacement larger than a preset length of the mobile terminal. In practical application, after the increase ratio of the signal strength is determined to be greater than the preset ratio, it is determined that the first cell meets the preset access condition; or after the mobile terminal is determined to have displacement which is greater than the preset length, determining that the first cell meets the preset access condition; and determining that the first cell meets the preset access condition after determining that the promotion ratio of the signal strength is greater than the preset ratio and the mobile terminal has displacement which is greater than the preset length.
In step 507, the access to the first cell is reattempted.
And after the first cell meets the preset access condition, the mobile terminal sends the connection request to the first cell again and tries to access the first cell again.
In the cell access method, under the condition of failure of accessing the first cell, the first communication environment information of the mobile terminal is acquired, the second cell is tried to be accessed, and the first cell is set as the forbidden access cell. Thereafter, it is determined whether a change in the communication environment has occurred by detecting at least one of the signal strength and the geographical location, the change in the communication environment making the first cell more suitable for access. In case the first cell is more suitable for access, the access to the first cell is re-attempted. By the embodiment of the disclosure, the problem that the whole network is not accessed any more due to access failure of one cell can be avoided, and therefore, the efficiency of network registration can be improved
