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.

The method and the device can be applied to the scene of network registration by using the SIM card. In the embodiment of the present application, the SIM card may be any SIM card containing an EHPLMN set, and may be, for example, an embedded SIM card (ESIM). Illustratively, the SIM card in the present application may be an ESIM card of an interpersonal product in which there are two types of ESIM cards, a master card and a daughter card. The ESIM card main card supports different networks across countries and operators, and can sign different global operator packages, so that the SIM card can be accessed to different global operator packages.

The network injection process of the conventional SIM card is described below by taking ESIM as an example. The set of EHLPMNs in the ESIM card stores all registerable network types, and the set of EHPLMN may be stored in the ESIM card in the form of a list, for example. There are two ways to card the web via ESIM. One mode is that after the communication device is started, ESIM card data and original EHPLMN data in the ESIM card are directly issued to the modem for network injection. And the modem searches for and registers networks in sequence according to the registration sequence of the EHPLMN in the original EHPLMN set in the ESIM card. In another network injection mode, the communication device obtains a Mobile Country Code (MCC) of a target network at a current location by reading broadcast information of a base station, matches the MCC of the network that can be registered stored in the obtained MCC and ESIM cards when first-round registration fails, and selects a target PLMN according to an obtained matching result.

In the existing network injection mode, the network searching and injecting time is long. For example, if the registration sequence of the PLMN of the ESIM card contracted operator in the current network environment is later compared in the ESIM card original EHPLMN set, the time for registering the network to acquire service is longer, and the user experience is poor. In addition, in a case where the network environment is complicated, for example, in a multi-country or regional border, the accuracy of acquiring the MCC may be reduced. If the wrong MCC is obtained, the wrong MCC is matched with the wrong network set, and the network re-injection time is long after the network selection is triggered again.

Illustratively, the inland network has an MCC of 460 and a hong kong MCC of 454. After entering hong kong from inland, there are two networks with MCCs 460 and 454. If the communication device is started up for the first time and resides in a network with MCC 460, the communication device can not be used for network registration for a long time after the ESIM card data is issued, and a user can not access the network for use. The user needs to restart the device only in the network environment with the MCC of 454 to successfully log in the network.

According to the network access method, the network injection is performed by using the EHPLMN set after the registration sequence is optimized, and the network registration speed can be improved.

In combination with fig. 1, the network registration method in the embodiment of the present application is described in detail by taking SIM card network injection as an example.

As shown in fig. 1, the network access method of the embodiment of the present application includes steps S110 to S130.

S110, an initial equivalent home public land mobile network EHPLMN set is obtained from a subscriber identity module SIM card.

The EHPLMN set in the SIM card stores all network types that the user can register with, and the EHPLMN set of the network that the SIM card can register with is first acquired before starting network registration.

And S120, optimizing the registration sequence of the EHPLMN in the EHPLMN set to obtain the optimized EHPLMN set.

In the prior art, the network registration is performed by using a fixed EHPLMN registration order, which takes a long time, so in the embodiment of the present application, the registration order of the EHPLMN in the initial EHPLMN set is optimized, and the EHPLMN after optimizing the registration order is used for network registration, which can shorten the time for the SIM card to log in the network.

Optionally, in the optimization of the EHPLMN registration order, the registration order of the initial EHPLMN may be optimized using the MCC. The MCC is used for uniquely identifying the country or region to which the network belongs, and the registration sequence of the EHPLMN in the EHPLMN set is optimized according to the MCC, so that the accuracy of an optimization result can be improved.

As an embodiment, the registration order of the EHPLMNs in the initial EHPLMN set may be optimized according to the MCC of the PLMN which is successfully registered by the SIM card last time. Specifically, the MCC that was successfully networked last time may be stored in the communication device, and when the registration order of the EHPLMN is optimized, the stored MCC that is successfully networked last time may be read, and the registration order of the EHPLMN is optimized according to the MCC that is successfully networked last time.

According to the technical scheme, the memorized MCC which is successful in network injection last time is utilized, the MCC can be quickly acquired, so that the registration sequence of the EHPLMN is optimized according to the MCC, and the network injection speed of the SIM card is improved.

As an example, the registration order of EHPLMNs in the initial EHPLMN set may be optimized according to MCCs in PLMNs collected by the modem. The modem collects the MCC of the PLMN in the network environment, and can optimize the registration sequence of the EHPLMN according to the collected MCC in the complex network environment, thereby improving the speed and the accuracy of SIM card network injection in the complex environment.

Optionally, before optimizing the EHPLMN registration order in the initial EHPLMN set according to the MCC in the PLMN collected by the modem, a Forbidden Public Land Mobile Network (FPLMN) containing no EHPLMN and forbidden to use may be sent to the modem to trigger the modem to collect the PLMN.

In the process of collecting the PLMN by the modem, a certain condition for stopping searching the network can be set, and when the condition for stopping searching the network is met, the modem stops collecting the PLMN. For example, the network searching stopping condition may be set to N seconds after receiving the report of the PLMN, where N is an integer; or M PLMN reports are received, wherein M is an integer.

In the embodiment of the application, the network searching of the modem is triggered by issuing the SIM card which does not contain the EHPLMN and the FPLMN, and the condition for stopping the network searching is set, so that the network searching process is accelerated, and the modem can quickly collect the MCC of the PLMN to optimize the registration sequence of the EHPLMN of the initial EHPLMN set.

According to one embodiment, the registration order of the EHPLMNs in the initial EHPLMN set may be optimized according to one or more of the MCC of the collected PLMNs, the initial EHPLMN set and the initial FPLMN set in the SIM card, and the PLMN that failed in the last network injection. The registration sequence of the EHPLMN is optimized by combining various factors, so that the accuracy of an optimization result can be improved.

Optionally, the network injection failure condition in the embodiment of the present application may include: the time from the first time of receiving the PLMN report after sending the SIM card data exceeds N seconds, wherein N is an integer; or after sending SIM card data, continuously receiving M PLMN reports which are inconsistent with the optimized EHPLMN set, wherein M is an integer.

By setting the condition of network injection failure, the network injection can be stopped in time when the condition is met, and the phenomenon that a large amount of time is consumed in the unsuccessful network injection process is avoided.

And S130, sending the optimized EHPLMN set to a modem so that the modem can register the SIM card with the network.

The optimized registration sequence of the EHPLMN in the EHPLMN set is adjusted according to one or more of the current network environment, the original network parameters in the SIM card, and the parameters of the last network registration, so that the network registration speed can be increased.

The following describes in detail a process of SIM card network injection for optimizing EHPLMN registration order in the initial EHPLMN set according to MCC with reference to fig. 2 and 3.

Fig. 2 is a flowchart of a network registration method for optimizing the registration order of EHPLMNs in the initial EHPLMN set according to the MCC of the last successful network injection when the MCC of the last successful network injection matches the MCC of the current target network. As shown in fig. 2, when the MCC of the last successful network injection matches with the MCC of the current target network, the network injection method for optimizing the registration order of the EHPLMNs in the initial EHPLMN set according to the MCC of the last successful network injection includes steps S210 to S250.

S210, reading the MCC successfully memorized in the previous network injection. For example, the network registration apparatus according to the embodiment of the present application may have a storage unit for storing MCCs successfully networked, and when the registration order of the EHPLMN is optimized, the MCCs successfully stored in the previous network registration may be read from the storage unit.

S220, constructing corresponding operator parameters (EHPLMN, FPLMN) and issuing the SIM card to the modem for network injection. In step S220, according to the obtained MCC that the last network injection was successful, the registration order of the EHPLMN in the initial EHPLMN set in the SIM card is optimized, or the FPLMN set in the SIM card is optimized. And sending the optimized SIM card data to a modem for network injection.

And S230, receiving the message that the ESIM network injection is successful. Through the optimization of the MCC on the EHPLMN registration sequence successfully injected last time, the modem can be quickly matched with a target network for injection, and a message indicating that the SIM card is successfully injected after the injection is successful is received.

And S240, deleting the timer for collecting the PLMN. In the embodiment of the application, a condition for judging the network injection failure is preset, for example, the network registration failure condition can be set to be more than N seconds after the SIM card data is issued and the PLMN is received for the first time, wherein N is an integer; or setting that M PLMNs continuously received are inconsistent with the EHPLMN list optimized before as a condition for determining the network injection failure, where M is an integer. After receiving the indication message of successful network injection, the timer for determining the network injection failure may be deleted.

S250, updating the memorized MCC. Specifically, after the current network deployment is successful, the MCC of the current network deployment success may be stored. For example, the network registration apparatus may store the MCC that is successfully annotated in the network to the memory unit, so as to update the MCC memory.

Fig. 3 is a flowchart of SIM card network injection for optimizing EHPLMN registration order according to one or more of the collected MCC, initial EHPLMN set in SIM card, and PLMN that failed in network injection last time when MCC that succeeded in network injection last time does not match MCC of current target network. As shown in fig. 3, when the MCC successfully used for the last network injection does not match the MCC of the current target network, the SIM card may be injected after optimizing the EHPLMN registration order according to one or more of the collected MCC, the initial EHPLMN set in the SIM card, and the PLMN failed for the last network injection according to the methods shown in steps S310 to S390.

Steps S310 to S340 are processes of optimizing the registration order of the EHPLMN in the SIM card according to the collected MCC of the PLMN or the last successful MCC of network injection.

And S310, reading the MCC which is successful in network injection last time. Specifically, after acquiring the MCC that the network injection was successful last time, step S340 is executed. If the MCC which is successfully annotated in the network last time is not acquired, for example, the communication device is started up for the first time to annotate the network; if no MCC successfully logged in the last network is saved, step S320 is executed.

And S320, modifying the SIM card operator parameters (clearing the EHPLMN and the FPLMN). Specifically, EHPLMN and FPLMN parameters preset in the SIM card may be cleared, where the EHPLMN and FPLMN parameters indicate all possible operator networks that may be accessed.

S330, the SIM card for clearing the PLMN card data is issued to the modem. And sending SIM card data which does not contain preset EHPLMN and FPLMN data to a modem to trigger the fast network searching.

S340, constructing corresponding operator parameters (EHPLMN, FPLMN) and issuing the SIM card to the modem. After the successful MCC of the last network injection is obtained, the registration sequence of the EHPLMN of the initial EHPLMN set of the SIM card is optimized according to the successful MCC of the last network injection, and the registration sequence of the FPLMN in the initial FPLMN set can also be optimized at the same time. And sending the SIM card data with the optimized PLMN registration sequence to a modem for network injection.

Steps S350 to S390 are processes of optimizing EHPLMN registration order according to one or more of collected MCC, initial EHPLMN set and initial FPLMN set in SIM card, and PLMN that failed in last network deployment, and correcting memorized MCC, when MCC that succeeded in last network deployment does not match MCC of current target network.

And S350, receiving the PLMN reported by the network searching. After the modem starts to perform network injection, the collection of the PLMN is started.

And S360, starting a 5-second timer, and collecting all MCCs reported to the network PLMN. The preset condition of network injection failure can be that the time from the first time of receiving the PLMN report after sending the SIM card data exceeds N seconds, wherein N is an integer; or after sending the SIM card data, continuously receiving M PLMN reports that the reports are inconsistent with the optimized EHPLMN set, wherein M is an integer. From the received PLMN report, a timer may be set, e.g., 5 seconds, and the PLMN may be collected during the timer.

And S370, when the timer expires or meets preset conditions and the number of network injection failures is less than 3, optimizing SIM card data according to the collected MCC set, and issuing SIM cards with optimized parameters (EHPLMN, FPLMN) to a modem. After the network injection failure is judged according to the preset network injection failure condition, the registration sequence of the EHPLMN of the initial EHPLMN set in the SIM card can be optimized according to one or more of the collected MCC of the PLMN, the initial EHPLMN set in the SIM card, the initial FPLMN set in the SIM card and the PLMN which failed in the network injection last time, and the optimized SIM card data is sent to the modem for network injection again.

In addition, the number of procedures for correcting the memorized MCC can be controlled, for example, the number of network injection failures is controlled to be less than 3.

And S380, successfully annotating the network, and clearing network-annotating failure times. And clearing the accumulated network injection failure times after the SIM card successfully injects the network again.

S390, correcting and memorizing. Specifically, after successful network injection, the new MCC that successfully injected the network is saved.

The MCC is obtained in multiple modes, the registration sequence of the EHPLMN in the initial EHPLMN set in the SIM card is optimized according to the MCC, the network injection speed of the SIM card can be accelerated according to simple judgment conditions, and the network injection stability in a complex network environment is enhanced.

In a laboratory test, a method for optimizing an EHPLMN registration sequence in a SIM card to perform network registration is adopted, and it takes 52 seconds for a network registration device to successfully load an operator package from power-on, where 18 seconds is power-on time and 34 seconds is network registration time. With the network registration method in the prior art, the time for successful network registration is 60 seconds.

In actual testing, the user entered hong Kong from inland to conduct the test. When the network registration device enters hong Kong from the inland for the first time, the network is started for the first time at the railway station of the hong Kong for network injection. The time from startup to successful network injection is 1 minute and 20 seconds.

Subsequently, after departure from the metro platform, the network registration device of the device is powered on again on the moving train, and it takes 40 seconds to successfully power on the network registration device and to successfully log in the network. After the network registration device is started up for the first time and the network is successfully logged in, the network registration device stores the MCC of hong Kong who successfully logged in the network. When the network registration device is started up again for testing, the network registration device is still in hong Kong, and the memorized MCC is matched with the region where the network registration device is located, so that the network can be quickly annotated by adopting the correctly memorized MCC to optimize the registration sequence of the EHPLMN, and the network annotation speed is increased.

Thirdly, returning to home from hong Kong, it took 50 seconds to successfully log on the network from the network registration device. After the inland is re-entered, the MCC which is successful in the previous network injection is not matched with the MCC in the current network environment, so that the registration sequence of the EHPLMN is re-optimized for network injection immediately according to the collected MCC, the initial EHPLMN, the initial FPLMN and the PLMN which is failed in the network injection after the network injection failure is judged according to the condition of the network injection failure, and the memorized MCC which is successful in the network injection is updated after the network injection is successful.
