The 3GPP aims to realize smooth transition from a 2G network to a 3G network, ensure backward compatibility of future technologies, and support easy network establishment and roaming and compatibility between systems.

The EPS is an Evolved Packet system of 3GPP, and is composed of an Evolved Universal Terrestrial Radio Access Network (E-UTRAN) and an Evolved Packet Core Network of 3GPP, also called 4G Core Network (EPC), where the E-UTRAN is equivalent to an LTE Access Network and includes a UE and an eNB, and the EPC includes a Mobility Management Entity (MME), a Serving GateWay (SGW) and a PDN GateWay (PDN GateWay, PGW).

The technical solution of the present invention will be described in detail with reference to the following embodiments.

Referring to fig. 2, fig. 2 is a schematic flowchart illustrating a network registration control method according to an embodiment of the present invention; as shown in fig. 2, the network registration control method may include:

201. and when applying for registering the LTE network to the base station, receiving a rejection message returned by the base station.

The execution subject of the embodiment of the invention is terminal equipment, and when the terminal equipment applies for registering an LTE network to a base station, if a rejection message is received, the rejection message is analyzed.

202. And when the rejection reason for rejecting the registration of the LTE network indicated by the rejection message is the first preset rejection reason, redirecting the rejection reason to the second preset rejection reason, and applying for registering the LTE network again to the base station.

If the rejection reason indicated by the rejection message is determined to be the first preset rejection reason, the rejection reason is redirected to the second preset rejection reason, and then the registration of the LTE network can be applied to the base station again under the second preset rejection reason, so that the situation that the terminal equipment sets the PS service and/or the CS service of the SIM card to be invalid under the first preset rejection reason, and the terminal equipment cannot try to register the LTE network before rebooting, so that the LTE network cannot be registered for a long time, can be avoided. Therefore, in the embodiment of the present invention, after the reject reason is determined as the first preset reject reason, the reject reason is redirected from the first preset reject reason to the second preset reject reason, so as to retry to register the LTE network, and improve the probability of joining the LTE network, that is, improve the 4G network online rate of the terminal device.

The first preset reject reason may be an EPS reject reason 7 or an EPS reject reason 8 specified by the protocol. Specifically, EPS reject cause 7: EPS service not allowed (EPS services not allowed), EPS reject cause 8: neither EPS services nor non-EPS services are allowed (EPS services and non-EPS served allowed).

The second preset reject reason may be an EPS reject reason 15 specified by the protocol, specifically, the EPS reject reason 15: the tracking area has No suitable cell (No survivable cells in tracking area).

By implementing the embodiment, when the rejection reason for rejecting network registration sent by the base station is the first preset rejection reason, registration can be continuously applied to the base station by redirecting the rejection reason to the second preset rejection reason, so that the defect that the terminal equipment cannot be registered to the LTE network for a long time due to the fact that the PS service is required to be set to be invalid or the CS service is required to be invalid when the rejection reason is the first preset rejection reason in the conventional technology can be overcome, the LTE network can be tried to be registered for many times, the probability that the terminal equipment is accessed to the LTE network is improved, the 4G network online rate of the terminal equipment is improved, and the service requirement can be met to the greatest extent.

Referring to fig. 3, fig. 3 is a schematic flow chart illustrating a network registration control method according to a second embodiment of the present invention; as shown in fig. 3, the network registration control method may include:

301. and applying for registering the LTE network with the base station.

The execution main body of the embodiment of the invention is terminal equipment, and the terminal equipment applies for registering an LTE network to a base station.

302. And receiving a rejection message returned by the base station.

If a rejection message is received, the rejection message is analyzed.

303. Judging whether the reject reason for rejecting the registration of the LTE network indicated by the reject message is a first preset reject reason or not; if yes, go to steps 304 to 306, and if no, in the embodiment of the present invention, execute the flow corresponding to the rejection reason according to the protocol specification.

304. The reject cause is redirected to a second preset reject cause.

305. And re-applying for registering the LTE network with the base station.

306. Judging whether the LTE network is successfully registered; if successful, the process goes to step 313, and if not, the process goes to step 307.

After the rejection reason is redirected from the first preset rejection reason to the second preset rejection reason, the terminal equipment can reapply for registering the LTE under the second preset rejection reason, and the success possibility of registering the LTE is improved. Illustratively, the EPS reject cause 7 or EPS reject cause 8 is redirected to the EPS reject cause 15 so that the PS service and/or CS service settings of the SIM are not invalidated and registration with the LTE network can still be attempted.

Optionally, when it is detected that the terminal device fails to register the LTE network again, the timer is started and starts timing, and if the timing duration meets the duration threshold, the LTE network registration is reapplied. Through the implementation mode, after the terminal equipment fails to reapply for registering the LTE network, reapplication can be carried out after a period of time is delayed, for example, reapplication is carried out after the first application fails and 30 seconds are delayed, so that the power consumption waste of the terminal equipment and the service burden of the terminal equipment caused by too frequent application and registration are avoided.

In the embodiment of the present invention, for power consumption and other service considerations, a preset attempt threshold (i.e. a maximum number of attempts) for continuously registering the LTE may be set, and if the number of registrations does not satisfy the preset attempt threshold, the LTE network may be continuously applied for registration, and when the number of registrations satisfies the preset attempt threshold, the 2G/3G network may be attempted to be registered.

307. Judging whether the registration times of registering the LTE network meet a preset trial threshold value or not; if so, go to step 308, otherwise, go to step 302.

According to the above description, if the registration times for registering the LTE network satisfy the predetermined attempt threshold by redirecting the reject cause, the process goes to steps 308-309 to attempt to register the 2G/3G network, and if the registration times for registering the LTE network do not satisfy the predetermined attempt threshold, the process goes to step 302 to determine whether a reject message is received.

308. And updating the state of the SIM card.

It can be understood that, if it is determined in step 303 that the reject reason for rejecting the registration of the LTE network indicated by the reject message is the first preset reject reason, if redirection for the reject reason is not performed, the terminal device may set the PS service and/or the CS service of the SIM card to be invalid, and after redirection for the reject reason, the terminal device may not set the PS service and/or the CS service of the SIM card to be invalid, and since the registration of the LTE network will be temporarily stopped and the registration of the 2G/3G network will be switched to after multiple failures of applying for registration of the LTE network occur, when step 308 is executed, the terminal device may switch to applying for the 2G/3G network by updating the state of the SIM card after multiple failures of registering the LTE network occur.

Specifically, the updating of the SIM card status may be updating the status of the SIM card redirected from the rejection reason to a status in which the PS service and/or the CS service are invalid, and the status of the SIM card of the terminal device redirected from the rejection reason may be a status in which the PS service and/or the CS service are normal.

309. Judging whether the SIM card is set to be invalid for PS service and/or invalid for CS service; if yes, go to steps 310-311, otherwise, execute the other corresponding procedures specified in the protocol.

In step 309, it is further determined whether the SIM card is set to PS service invalid and/or CS service invalid.

310. Detecting whether the data service of the 2G/3G network is normal or not; if so, the process goes to step 311, otherwise, the process goes to step 316.

It can be understood that after the SIM card is set to be invalid for the PS service and/or the CS service, the application for registering the 2G/3G network further determines whether to register the 2G/3G network and whether the data service is normal after registering the 2G/3G network, and if so, the process goes to step 311.

311. Judging whether the LAC is changed or not; if so, go to step 312, otherwise, keep the current state.

If the 2G/3G network can be normally registered, a PING test is tried, if the network can be PING successfully, the LTE network can be tried again when a Location Area Code (LAC) changes, because the LTE network cannot be registered in a part of areas, but the LTE network may be registered after the terminal device moves to another Area (i.e., after the LAC changes), so in the embodiment of the present invention, the probability of registering the LTE network is improved by considering power consumption and re-applying the LTE network after the LAC changes.

312. The SIM card is set to be PS service normal and/or CS service normal.

It should be noted that, when the LAC is changed, the state of the SIM card needs to be reset to be normal for the PS service and/or the CS service, and the LTE network registration can be reapplied in this state.

313. And applying for registering the LTE network with the base station.

314. Judging whether to normally register in the LTE network; if so, go to step 315, otherwise, go to step 302.

Optionally, if the terminal device cannot successfully register to the LTE network even when the LAC changes, the process may also turn to 307, and a registration success rate is improved by combining multiple registration attempts.

315. Camping on an LTE network.

And if the LTE network registration is tried successfully, residing on the LTE network, otherwise, continuously judging the rejection reason, and re-applying according to the rejection reason.

In addition, after the LTE network registration is successful, the terminal device also needs to reply the validity of the SIM card to the base station.

316. Reside in the 2G/3G network.

After the terminal equipment cannot register the LTE network, the terminal equipment firstly selects to register the 2G/3G network so as to ensure that part of services run normally.

It can be seen that, by implementing the above embodiment, when the rejection reason for rejecting network registration sent by the base station is the first preset rejection reason, the registration is applied to the base station again in a manner of redirecting the rejection reason to the second preset rejection reason, so that the defect that the terminal device cannot be registered in the LTE network for a long time due to the fact that the PS service is required to be set invalid or the CS service is required to be set invalid when the rejection reason is the first preset rejection reason in the conventional technology can be overcome; if the re-registration fails and the registration times meet the preset attempt threshold, the state of the SIM card is updated to apply for accessing the 2G/3G network, if the registration on the 2G/3G network is successful and the data service is normal under the 2G/3G network, judging whether the LAC is changed, when the LAC sends the change, the SIM card status is set to the PS service and/or the CS service is normal again, to try again to apply for the LTE network, to detect whether the LTE network can be successfully applied after the change of the camping area, therefore, the embodiment of the invention can try to register the LTE network for a plurality of times after the reason of the redirection rejection, and attempting to register the LTE network again after a change in LAC after failing to attempt to register the LTE network for a plurality of times, the probability of the terminal equipment accessing the LTE network is improved, so that the 4G network online rate of the terminal equipment is improved, and the service requirement is met to the greatest extent.

the registration module 420 is configured to, when the rejection reason for rejecting registration of the LTE network indicated by the rejection message is the first preset rejection reason, redirect the rejection reason to the second preset rejection reason, and reapply for registration of the LTE network to the base station.

By implementing the device, when the rejection reason for rejecting network registration sent by the base station is the first preset rejection reason, registration can be continuously applied to the base station by redirecting the rejection reason to the second preset rejection reason, so that the defect that the terminal equipment cannot be registered to the LTE network for a long time due to the fact that the PS service is required to be set to be invalid or the CS service is required to be invalid when the rejection reason is the first preset rejection reason in the prior art can be overcome, the LTE network can be tried to be registered for many times, the probability that the terminal equipment is accessed to the LTE network is improved, the 4G network online rate of the terminal equipment is improved, and the service requirement can be met to the greatest extent.
