Description

Base station registration method and mobile terminal

Technical Field

The present invention relates to the field of communications technologies, and in particular, to a base station registration method and a mobile terminal.

Background

At present, a mobile terminal such as a mobile phone needs to perform registration or re-registration of base stations when the mobile terminal is powered on, dropped or moved in position, and at this time, the mobile terminal searches for base stations that can be registered and sorts the base stations according to a certain sequence (for example, the sequence from strong to weak signal strength) to form a candidate base station list. And then, the mobile terminal preferentially tries to register to the base station which is ranked at the head in the candidate base station list, and after the registration is successful, the base station which is ranked at the head in the candidate base station list provides data service for the mobile terminal.

However, some people forge a base station (the forged base station is referred to as a pseudo base station in the following description), and the signal strength of the pseudo base station is very strong, and in this case, the pseudo base station is often ranked at the head of the candidate base station list, and the mobile terminal is very easy to register to the pseudo base station. After successfully registering to the pseudo base station, the mobile terminal is prone to receive bad contents such as telecom fraud, reaction information and the like, and information in a Subscriber Identity Module (SIM) card of the mobile terminal is prone to leakage.

Disclosure of Invention

Embodiments of the present invention provide a base station registration method and a mobile terminal, so as to solve the problems in the prior art that a mobile terminal is easily registered to a pseudo base station, so that the mobile terminal receives bad contents such as telecommunication fraud and reaction information, and information in an SIM card of the mobile terminal is leaked.

In order to solve the technical problem, the invention is realized as follows:

in a first aspect, an embodiment of the present invention provides a base station registration method, which is applied to a mobile terminal, and the method includes:

if the mobile terminal is to perform base station registration or re-registration, receiving a system message broadcast by a first base station; the first base station is a base station which is arranged at the head in a candidate base station list according to a preset sequence;

judging whether the first base station accords with the characteristics of a pseudo base station or not according to the system message;

if the first base station accords with the characteristics of the pseudo base station, sending a registration request to a second base station; and the second base station is a base station which is ranked only next to the first base station in the candidate base station list according to a preset sequence.

In a second aspect, an embodiment of the present invention provides a mobile terminal, where the mobile terminal includes:

a receiving module, configured to receive a system message broadcast by a first base station if the mobile terminal is to perform registration or re-registration of a base station; the first base station is a base station which is arranged at the head in a candidate base station list according to a preset sequence;

the judging module is used for judging whether the first base station accords with the characteristics of a pseudo base station or not according to the system message;

a first sending module, configured to send a registration request to a second base station if the first base station meets the pseudo base station characteristics; and the second base station is a base station which is ranked only next to the first base station in the candidate base station list according to a preset sequence.

In a third aspect, an embodiment of the present invention provides a mobile terminal, including a processor, a memory, and a computer program stored in the memory and operable on the processor, where the computer program, when executed by the processor, implements the steps of the foregoing base station registration method.

In a fourth aspect, an embodiment of the present invention provides a computer-readable storage medium, where a computer program is stored on the computer-readable storage medium, and when the computer program is executed by a processor, the steps of the base station registration method are implemented.

In the embodiment of the invention, if the base station needs to be registered or re-registered, the mobile terminal does not directly try to register to the first base station which is arranged at the head in the candidate base station list according to the preset sequence, but receives the system message broadcasted by the first base station first, and judges whether the first base station accords with the characteristics of the pseudo base station according to the received system message. If the determination result is yes, the first base station is very likely to be a pseudo base station, and therefore, the mobile terminal does not attempt to register to the first base station, but attempts to register to the second base station, so as to avoid receiving bad contents such as telecom fraud, reverse information and the like after the mobile terminal registers to the first base station, and avoid information leakage in the SIM card of the mobile terminal.

Therefore, the embodiment of the invention can better solve the problems that the mobile terminal in the prior art is easy to register to the pseudo base station, so that the mobile terminal receives bad contents such as telecom fraud, reverse information and the like, and information in the SIM card of the mobile terminal is leaked.

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 some, not all, embodiments of the present invention. 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.

The following first describes a base station registration method provided in an embodiment of the present invention.

It should be noted that the base station registration method provided by the embodiment of the present invention is applied to a mobile terminal. Specifically, the mobile terminal may be any device having a communication function, such as: computers (Computer), mobile phones, tablet computers (tablet personal Computer), Laptop computers (Laptop Computer), Personal Digital Assistants (PDA), Mobile Internet Devices (MID), Wearable devices (Wearable Device), and the like.

Referring to fig. 1, a flowchart of a base station registration method according to an embodiment of the present invention is shown. As shown in fig. 1, the method is applied to a mobile terminal, and includes the following steps:

step 101, if a mobile terminal is to perform base station registration or re-registration, receiving a system message broadcast by a first base station; the first base station is a base station which is arranged at the head in the candidate base station list according to a preset sequence.

The candidate base station list may be a list determined by the searched registrable base stations when the mobile terminal is to perform registration or re-registration of the base stations. The candidate base station list generally includes at least two base stations, and each base station in the candidate base station list may be specifically sorted according to the sequence from strong signal strength to weak signal strength (that is, the preset sequence is the sequence from strong signal strength to weak signal strength). It should be noted that, a base station ranked at the top in the candidate base station list according to the preset order may be a pseudo base station, and a base station not ranked at the top is generally not a pseudo base station but a normal base station, so that the first base station may be a pseudo base station, and the second base station is a normal base station.

In the embodiment of the present invention, after the candidate base station list is determined, since the first base station ordered at the top in the candidate base station list according to the preset order may be a pseudo base station, in order to avoid the mobile terminal registering to the pseudo base station, the mobile terminal does not immediately attempt to register to the first base station, but performs the operation of the synchronization channel with respect to the first base station. After the operation of the synchronization channel is completed, the mobile terminal receives a system message broadcast by the first base station. As will be understood by those skilled in the art, the System message broadcast by the first base station includes a plurality of System Information Blocks (SIBs), such as SIB1, SIB2, SIB 3. Thereafter, the mobile terminal performs the subsequent step 102 according to the received system message.

Step 102, judging whether the first base station accords with the characteristics of a pseudo base station or not according to the system information; if the first base station meets the characteristics of the pseudo base station, step 103 is executed.

It should be noted that, according to the system message, the specific implementation form of judging whether the first base station conforms to the characteristics of the pseudo base station is various, and for clarity of layout, the following description is given by way of example.

Step 103, sending a registration request to the second base station; and the second base station is a base station which is arranged in the candidate base station list according to a preset sequence and is only next to the first base station.

In the case where the first base station conforms to the pseudo base station characteristic, the mobile terminal may send a registration request to the second base station to attempt registration with the second base station. After the mobile terminal sends a registration request to the second base station, the mobile terminal and the second base station may perform bidirectional authentication by using a Long Term Evolution (Long Term Evolution) technology. Then, if the mobile terminal is successfully registered to the second base station, the second base station may provide normal data service for the mobile terminal to ensure normal operation of the mobile terminal. If the mobile terminal fails to register with the second base station, the mobile terminal may send a registration request to other base stations that can register, for example, send a registration request to a base station that is ranked in the candidate base station list after the second base station according to a preset order, so as to attempt to register with other base stations.

Optionally, if the first base station conforms to the characteristics of the pseudo base station, sending a registration request to the second base station, including:

if the first base station accords with the characteristics of the pseudo base station, judging whether the difference value between the signal intensity of the first base station and the signal intensity of the second base station is smaller than a preset signal intensity difference value;

and if the difference is not smaller than the preset signal strength difference, sending a registration request to the second base station.

The preset signal strength difference may be 5dbm, 8dbm, or 10dbm, and certainly, the preset signal strength difference is not limited thereto, and may be determined according to an actual situation, which is not limited in the present invention.

Generally, the signal strength of the pseudo base station is much stronger than that of the normal base station, and therefore, in order to more accurately determine whether the first base station is the pseudo base station when the first base station is determined to conform to the characteristics of the pseudo base station, the mobile terminal may further determine whether a difference between the signal strength of the first base station and the signal strength of the second base station is smaller than a preset signal strength difference.

If the result is not less than the first threshold, the possibility that the first base station is a pseudo base station is further increased, and at this time, the mobile terminal sends a registration request to the second base station to attempt to register to the second base station. If the result is less than the first threshold, the possibility that the first base station is a pseudo base station is greatly reduced, and therefore, the mobile terminal sends a registration request to the first base station to attempt to register to the first base station. Since the first base station is the base station with the strongest signal strength in the candidate base station list, the data service quality on the mobile terminal can be ensured.

It should be noted that, after the mobile terminal sends the registration request to the first base station, the mobile terminal and the first base station may also perform bidirectional authentication by using the LTE technology.

It can be seen that, in the embodiment of the present invention, by comparing the difference between the signal strengths of the first base station and the second base station with the preset signal strength difference, the mobile terminal can more accurately determine that the first base station is a pseudo base station, and send a registration request to the second base station in this case, so as to avoid the mobile terminal from registering to the pseudo base station as much as possible.

Referring to fig. 2, a second flowchart of a base station registration method according to an embodiment of the present invention is shown. This embodiment differs from the embodiment shown in fig. 1 in that: the processing operation of the mobile terminal is added under the condition that the first base station is judged not to conform to the characteristics of the pseudo base station. As shown in fig. 2, the method is applied to a mobile terminal, and includes the following steps:

step 201, if the mobile terminal is to perform base station registration or re-registration, receiving a system message broadcast by a first base station; the first base station is a base station which is arranged at the head in the candidate base station list according to a preset sequence.

Step 202, judging whether the first base station accords with the characteristics of a pseudo base station or not according to the system information; if the first base station meets the characteristics of the pseudo base station, executing step 203; if the first base station does not conform to the pseudo base station characteristics, go to step 204.

Step 203, sending a registration request to the second base station; and the second base station is a base station which is arranged in the candidate base station list according to a preset sequence and is only next to the first base station.

The specific implementation process of steps 201 to 203 may refer to the description of steps 101 to 103 in the embodiment shown in fig. 1, and will not be described herein again.

Step 204, sending a registration request to the first base station.

In the embodiment of the present invention, when the first base station does not conform to the characteristics of the pseudo base station, the first base station may be regarded as not being the pseudo base station, and therefore, the mobile terminal directly sends a registration request to the first base station to attempt to register with the first base station.

Step 205, if the registration to the first base station for N consecutive times fails, sending a registration request to the second base station; wherein N is greater than or equal to 2.

N may be 2, 3, 4, 5, or any integer greater than 5, which is not described herein again.

It should be noted that, after the mobile terminal performs step 204 to send the registration request to the first base station, if the mobile terminal successfully registers to the first base station, the first base station provides a normal data service for the mobile terminal, so as to ensure the normal operation of the mobile terminal. If the mobile terminal fails to register with the first base station, the mobile terminal will resend the registration request to the first base station. After re-sending the registration request to the first base station, if the mobile terminal still fails to register with the first base station, the mobile terminal will again send the registration request to the first base station.

Assuming that the mobile terminal fails to register with the first base station for 5 consecutive times, it may be considered that the first base station has a failure, which may not perform normal data interaction with the mobile terminal, and therefore, the mobile terminal may send a registration request to the second base station to attempt to register with the second base station. After the mobile terminal successfully registers with the second base station, the second base station can provide normal data service for the mobile terminal.

It can be seen that, in the embodiment of the present invention, when N consecutive attempts to register to the first base station belonging to the normal base station fail, the mobile terminal may attempt to register to the second base station, so that the second base station provides a normal data service for the mobile terminal after the registration is successful, thereby ensuring normal operation of the mobile terminal.

Optionally, determining whether the first base station conforms to the pseudo base station characteristic according to the system message includes:

judging whether the adsorption performance of the first base station is consistent with the adsorption performance of a preset pseudo base station or not according to the system message, and judging whether the service processing performance of the first base station is consistent with the service processing performance of the preset pseudo base station or not according to the system message;

if the adsorption performance accords with the adsorption performance of the preset pseudo base station and the service processing performance accords with the service processing performance of the preset pseudo base station, determining that the first base station accords with the characteristics of the pseudo base station;

and if the adsorption performance does not accord with the adsorption performance of the preset pseudo base station and/or the service processing performance does not accord with the service processing performance of the preset pseudo base station, determining that the first base station does not accord with the characteristics of the pseudo base station.

It can be understood that the pseudo base station needs to attract a large number of mobile terminals to register, so that the adsorption performance of the pseudo base station is very strong; the pseudo base station only needs to perform simple signaling interaction with the mobile terminal, and does not need to provide normal data service for the mobile terminal, so that the service processing performance of the pseudo base station is very poor. In contrast, in consideration of communication quality, a normal base station avoids serving a large number of mobile terminals at the same time as much as possible, so that the adsorption performance of the normal base station is not very strong; the normal base station needs to provide normal data service for the mobile terminal besides performing signaling interaction with the mobile terminal, so the service processing performance of the normal base station is very strong.

In view of this, in the embodiment of the present invention, the mobile terminal may store a preset pseudo base station adsorption performance (a base station with the preset pseudo base station adsorption performance is very easy to adsorb the mobile terminal for registration) and a preset pseudo base station service processing performance (a base station with the preset pseudo base station service processing performance is difficult to provide a normal data service for the mobile terminal). After receiving the system message broadcasted by the first base station, the mobile terminal judges whether the adsorption performance of the first base station is consistent with the adsorption performance of the preset pseudo base station or not according to the received system message, and judges whether the service processing performance of the first base station is consistent with the service processing performance of the preset pseudo base station or not according to the received system message.

If the adsorption performance of the first base station is consistent with the adsorption performance of the preset pseudo base station, and the service processing performance of the first base station is consistent with the service processing performance of the preset pseudo base station, this indicates that the first base station is very easy to attract the mobile terminal to register, and the first base station is difficult to provide normal data service for the mobile terminal, then the probability that the first base station is the pseudo base station is high, and therefore the mobile terminal determines that the first base station is consistent with the characteristics of the pseudo base station.

If the adsorption performance of the first base station does not conform to the preset pseudo base station adsorption performance and/or the service processing performance of the first base station does not conform to the preset pseudo base station service processing performance, which indicates that the first base station is not easy to attract the mobile terminal for registration, and/or the first base station can provide normal data service for the mobile terminal, then the probability that the first base station is a pseudo base station is not high, and therefore, the mobile terminal determines that the first base station does not conform to the pseudo base station characteristics.

Therefore, in the embodiment of the invention, the mobile terminal can conveniently and quickly determine whether the first base station accords with the characteristics of the pseudo base station.

Optionally, the determining, according to the system message, whether the adsorption performance of the first base station is consistent with the adsorption performance of the preset pseudo base station includes:

and acquiring the reselection priority and the minimum access level associated value in the system message.

Specifically, the mobile terminal may obtain q-RxLevMin (unit is dbm) from SIB1 in the system message, where q-RxLevMin is a minimum access level associated value, and generally, the minimum access level is 2 times q-RxLevMin. The mobile terminal may obtain the cell reselection priority from the SIB3 in the system message, where the cell reselection priority is the reselection priority.

And determining a target access level correlation value according to the minimum access level correlation value.

It should be noted that, the specific implementation forms of determining the target access level associated value according to the minimum access level associated value are various, and two specific implementation forms are described below as examples.

In a first implementation form, the determining the target access level associated value is based on a minimum access level associated value, including

The minimum access level associated value is determined as the target access level associated value.

In a first implementation form, the mobile terminal may directly determine q-RxLevMin in SIB1 as the target access level associated value. It can be seen that the operation of determining the target access level associated value by the mobile terminal is very convenient and fast to implement.

In a second implementation form, the target access level associated value is determined according to the minimum access level associated value, including

And acquiring an offset value of the minimum access level associated value from the system message, calculating a sum value of the minimum access level associated value and the offset value, and determining the sum value as a target access level associated value.

Specifically, the mobile terminal may obtain q-RxLevMinOffset (unit is dbm) from SIB1 in the system message, where q-RxLevMinOffset is an offset value of the minimum access level related value.

In a second implementation, the mobile terminal may determine the sum of q-RxLevMin and q-RxLevMinOffset in SIB1 as the target access level associated value. It can be seen that the operation of determining the target access level associated value by the mobile terminal is also very convenient and fast to implement.

If the reselection priority is higher than the preset reselection priority and the target access level correlation value is smaller than the preset access level correlation value, determining that the adsorption performance of the first base station is consistent with the adsorption performance of the preset pseudo base station;

and if the reselection priority is not higher than the preset reselection priority and/or the target access level correlation value is not smaller than the preset access level correlation value, determining that the adsorption performance of the first base station does not accord with the adsorption performance of the preset pseudo base station.

The preset reselection priority may be 6, and the preset access level associated value may be-65 dbm, and of course, values of the preset reselection priority and the preset access level associated value are not limited thereto, and may be determined specifically according to an actual situation, which is not limited in this embodiment of the present invention.

After receiving the system message broadcast by the first base station, the mobile terminal may acquire the cell Reselection Priority and the q-RxLevMin in the system message. Next, the mobile terminal determines a target access level associated value Z (i.e., q-RxLevMin, or the sum of q-RxLevMin and q-RxLevMinOffset) from q-RxLevMin. Assuming that the preset reselection priority is 6 and the preset access level association value is-65 dbm, after determining the target access level association value Z, the mobile terminal compares the cell reselection priority with 6 and compares the target access level association value Z with-65 dbm.

It can be understood that, if the target access level correlation value Z is smaller than-65 dbm, which indicates that the minimum access level corresponding to the first base station is too small, the first base station has little restriction on the mobile terminal capable of registering itself, and the camping condition corresponding to the first base station is too low, it can be considered that the first base station has a feature of attracting the mobile terminal to register very easily. If the cell Reselection Priority is higher than 6, for example, 7 (the Reselection Priority is the current highest Reselection Priority), since the mobile terminal usually selects to register to the base station with the highest Reselection Priority, the first base station may also be considered to have a characteristic of attracting the mobile terminal to register very easily.

Therefore, if the mobile terminal determines through comparison that the target access level correlation value Z is smaller than-65 dbm and the cell reselection Priority is higher than 6, it can be considered that the first base station has a characteristic of attracting the mobile terminal to register very easily, and at this time, the mobile terminal determines that the adsorption performance of the first base station is consistent with the adsorption performance of the preset pseudo base station. If the mobile terminal determines through comparison that the target access level correlation value Z is greater than or equal to-65 dbm and the cell Reselection Priority is not greater than 6, it can be considered that the first base station does not have a feature of easily attracting the mobile terminal to register, and at this time, the mobile terminal determines that the adsorption performance of the first base station does not conform to the adsorption performance of the preset pseudo base station.

Therefore, the embodiment of the invention can conveniently and quickly determine whether the adsorption performance of the first base station is consistent with the preset adsorption performance of the pseudo base station.

Optionally, judging whether the service processing performance of the first base station conforms to the service processing performance of the preset pseudo base station according to the system message, including:

and acquiring the ratio of uplink and downlink subframes in the system message.

Specifically, the mobile terminal may obtain subframe Assignment from SIB3 in the system message, where this parameter is the uplink and downlink subframe ratio (i.e., the ratio of the uplink bandwidth to the downlink bandwidth).

If the ratio of the uplink subframe to the downlink subframe is greater than the preset ratio of the uplink subframe to the downlink subframe, and other SIBs except SIB1, SIB2 and SIB3 do not exist in the system message, determining that the service processing performance of the first base station conforms to the service processing performance of the preset pseudo base station;

and if the uplink and downlink subframe ratio is not greater than the preset uplink and downlink subframe ratio and/or other SIBs except SIB1, SIB2 and SIB3 exist in the system message, determining that the service processing performance of the first base station does not accord with the service processing performance of the preset pseudo base station.

The preset ratio of the uplink subframe to the downlink subframe may be 1/3, and certainly, a value of the preset ratio of the uplink subframe to the downlink subframe is not limited to this, and may be determined specifically according to an actual situation, which is not limited in this embodiment of the present invention.

After receiving the system message broadcast by the first base station, the mobile terminal may acquire subframe Assignment in the system message. Assuming that the preset uplink and downlink subframe ratio is 1/3, after acquiring subframe Assignment, the mobile terminal may compare subframe Assignment with 1/3, and determine whether there are other SIBs besides SIB1, SIB2, and SIB3 in the system message.

It can be understood that, in order to provide a normal data service for the registered mobile terminal, the normal base station needs to provide a large amount of downlink data traffic, so that the uplink and downlink subframe ratio of the normal base station is generally smaller, for example, 1/3, and thus the service processing performance of the normal base station is generally better. In comparison, the pseudo base station only needs to perform simple signaling interaction with the mobile terminal, and does not need to provide a large amount of downlink data traffic, so that the ratio of uplink and downlink subframes of the pseudo base station is generally not small (for example, 1/1), and thus the service processing performance of the pseudo base station is generally poor. Therefore, if the subframe Assignment is greater than 1/3, the first base station may be considered to have a characteristic of poor traffic handling performance.

In addition, the system message broadcasted by the normal base station generally includes, in addition to SIB1, SIB2, and SIB3, other SIBs such as SIB4, SIB5, SIB6, SIB7, and SIB8, so as to provide the neighboring cell configuration parameters related to the same frequency/different frequency handover through the other SIBs, and thus, the normal base station can perform normal interaction with the neighboring cell base station based on the neighboring cell configuration information, so as to ensure the service processing performance of the normal base station. In comparison, the pseudo base station does not need to interact with the base station of the neighboring cell, and is isolated, so the service processing performance is generally poor. Therefore, if there is no SIB other than SIB1, SIB2, and SIB3 in the system message, the first base station may be considered to have a characteristic of poor service handling performance.

Therefore, if the mobile terminal determines that the subframe Assignment is greater than 1/3 and there is no SIB other than SIB1, SIB2, and SIB3 in the system message, it may be considered that the first base station has a characteristic of poor service processing performance, and at this time, the mobile terminal may determine that the service processing performance of the first base station matches the preset pseudo base station adsorption performance. If the mobile terminal determines that the subframe Assignment is not greater than 1/3, and/or that there are other SIBs other than SIB1, SIB2, and SIB3 in the system message, it may be considered that the service processing performance of the first base station is not poor, and at this time, the mobile terminal may determine that the service processing performance of the first base station does not match the preset pseudo base station adsorption performance.

Therefore, the embodiment of the invention can conveniently and quickly determine whether the service processing performance of the first base station is consistent with the adsorption performance of the preset pseudo base station.

The following describes a specific implementation process of an embodiment of the present invention with a specific example.

The mobile terminal determines the candidate base station list in case of needing to perform registration or re-registration of the base station. Suppose that the candidate base station list determined by the mobile terminal includes four base stations ordered according to the sequence of strong signal strength to weak signal strength, the candidate base station list ordered at the top is base station a (base station a may be regarded as the first base station in the above description), the candidate base station list ordered at the second position is base station B (base station B may be regarded as the second base station in the above description), the candidate base station list ordered at the third position is base station C, and the candidate base station list ordered at the fourth position is base station D.

After determining the candidate base station list, the mobile terminal receives a system message broadcasted by the base station A, judges whether the adsorption performance of the base station A is consistent with the adsorption performance of the preset pseudo base station according to the system message, and judges whether the service processing performance of the base station A is consistent with the service processing performance of the preset pseudo base station according to the system message. If the two judgment results are yes, the mobile terminal obtains the signal strength X1 of the base station a and the signal strength X2 of the base station B, and judges whether the difference between X1 and X2 is greater than a preset signal strength difference (e.g., 10 dbm).

Generally, the signal strength of the pseudo base station is much stronger than that of the normal base station, so if the difference between X1 and X2 is greater than 10dbm, the probability that the base station a is a pseudo base station is very high, and at this time, the mobile terminal sends a registration request to the base station B to attempt to register to the base station B, and the mobile terminal can also adjust the ranking of the base station a in the candidate base station list, for example, adjust the base station a to the rear of the base station D. In contrast, if the difference between X1 and X2 is not greater than 10dbm, even if the adsorption performance of base station a coincides with the preset pseudo base station adsorption performance and the traffic processing performance of base station a coincides with the preset pseudo base station traffic processing performance, base station a is likely not a pseudo base station, and thus, the mobile terminal transmits a registration request to base station a to attempt registration with base station a. If the mobile terminal fails to register to base station a for N consecutive attempts, the mobile terminal may send a registration request to base station B.

After the mobile terminal sends the registration request to the base station B, it may be considered that the mobile terminal has failed to register to the base station B, assuming that the mobile terminal is rejected from registration, or that a Radio Resource Control (RRC) connection is established between the mobile terminal and the base station B does not respond to the registration request. At this time, the mobile terminal sends a registration request to the base station C to attempt to register with the base station C.

Assuming that the mobile terminal also fails to attempt to register with base station C, the mobile terminal then continues to attempt to register with base station D, and the attempt to register with base station D also fails. At this time, the mobile terminal sends a registration request to the base station a to attempt to register with the base station a. After the mobile terminal successfully registers with base station a, base station a provides data services to the mobile terminal.
