It is obvious that the described embodiments are only a part of the embodiments of the present invention, but not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative efforts are within the scope of the present invention.

The terms "first", "second" and "third" and the like in the specification and claims of the present invention and the above drawings are used to distinguish different objects, and are not intended to describe a specific order. Moreover, the term "comprise" and any variants thereof are intended to cover a non-exclusive inclusion. For example, a process, method, system, product, or device that comprises a series of steps or units is not limited to the listed steps or units, but optionally also includes steps or units not listed, or alternatively Other steps or units inherent to these processes, methods, products or equipment.

FIG. 1 is a flowchart of a first embodiment of an information update method according to an embodiment of the present invention. Real In an embodiment, the information update method is applied to a terminal, and the terminal accesses a communication network through a smart card, and the terminal includes a mobile phone, a tablet computer, a computer, a wearable device, and the like. The information updating method includes the following steps S101-S103.

In step S101, a registration request is initiated to the network side, and when the registration is successful, the uniform resource identifier URI returned by the network side is received, and the URI includes number information.

In this step, the terminal accesses the network by using the smart card. After the network is camped on, the terminal initiates a registration request to the network side. The terminal is preferably an LTE (Long Term Evolution) terminal, and the network is an LTE network. It can be understood that the LTE network includes FDD-LTE (Frequency Division Duplexing) and TDD-LTE (Time Division Duplexing) according to different operators. The terminal initiates an IMS (Internet Protocol Multimedia Subsystem) registration request to the network side. When the registration is successful, the network side returns a registration success response message. The response information includes a URI (Uniform Resource Identifier), wherein the URI includes number information. The number information is the number information of the smart card. For example, if the operator used by the user is China Mobile, the number information is digital information similar to the format 13901234567.

In step S102, the mobile subscriber integrated service digital network number MSISDN in the smart card is obtained.

In this step, the MSISDN (Mobile Subscriber International Integrated Service Digital Network Number) of the smart card is obtained. Generally, the MSISDN is composed of three parts, namely, a CC (Country Code), an NDC (National Destination Code), and a SN (Subscriber Number). Among them, CC is used to distinguish mobile users in different countries. For example, China's country code is 86. NDC is also known as the network access number, which is used to distinguish different operators. For example, China Mobile's NDC includes 134-139, 150-152, and 188; China Unicom's NDC includes 130-132, 185, and 186; China Telecom's NDC includes 133, 180, and 189. In actual use, NDC+SN is the mobile phone number in the usual sense. In this embodiment, the corresponding MSISDN is obtained by reading the data information of the smart card. Since the MSISDN is stored in a specified location in the smart card, the corresponding MSISDN can be obtained by accessing the specified location.

In step S103, if the MSISDN and the number information in the URI are different, the MSISDN is updated according to the number information in the URI.

In this step, it is determined whether the MSISDN and the number information in the URI are the same. If not, the MSISDN is updated according to the number information in the URI. When the MSISDN and the number information in the URI are different, it indicates that the MSISDN in the smart card is not updated, because the operator usually does not write the MSISDN when making the smart card. Therefore, according to the number information in the URI, Update the MSISDN. For example, if the number information in the URI is 13901234567, the MSISDN is updated to +8613901234567, where +86 is CC and 13901234567 is NDC+SN, so that the MSISDN in the smart card can be ensured to be accurate. Since the existing mobile terminal has the function of viewing the local number, at this time, the correct number information can be viewed by viewing the local number, thereby facilitating the user without the user's memory.

The information update method in the embodiment of the present invention, by initiating a registration request to the network side, receives the uniform resource identifier returned by the network side when the registration request is successful, and obtains the number information included in the uniform resource identifier, and the number is included in the number. When the information is inconsistent with the mobile subscriber integrated service digital network number in the smart card, the mobile subscriber integrated service digital network number is updated according to the number information, so that the number corresponding to the smart card can be written into the smart card, thereby eliminating the need for the user to memorize the local number. User viewing improves user experience.

FIG. 2 is a flowchart of a second embodiment of an information update method according to an embodiment of the present invention. In the present embodiment, the information updating method includes steps S201-S207.

In step S201, a registration request is initiated to the network side.

In this step, when the terminal initiates a registration request to the network side, the terminal initiates an IMS registration request by using a PDN (Public Data Network) default bearer of the IMS, where the registration request is included according to the IMSI (International Mobile) Subscriber Identification Number (IMP) is derived from the Internet Protocol Multimedia Public Identity (IMP) or the Internet Protocol Multimedia Private Identity (IMPI). The IMSI is stored in the smart card and can be used to distinguish the valid information of the mobile user, and the total length thereof does not exceed 15 bits, and the numbers of 0-9 are also used. The IMSI consists of three parts: MCC (Mobile Country Code), MNC (Mobile Network Code), and MSIN (Mobile Subscriber Identification Number). Among them, the MCC is the country code of the mobile user, which accounts for 3 digits. For example, the MCC of China is 460. The MNC is a mobile network number, which consists of two or three digits, and is used to identify the mobile communication network to which the mobile subscriber belongs. For example, among operators China Mobile's Mobile Network Coding (MNC) is 00; MSIN is a mobile subscriber identity to identify mobile subscribers in a mobile communications network. The IMSI is different from the IMEI (International Mobile Equipment Identity) of the mobile device, and the IMEI is bound to the terminal. The IMSI is bound to the smart card. In this embodiment, when the registration request is initiated, the IMPU and the IMPI are derived according to the IMSI.

In step S202, it is determined whether the registration is successful.

In this step, it is determined whether the registration is successful, and whether the registration is successful can be determined by whether a successful response is received. If the successful response is received, it indicates that the registration is successful, and the process proceeds to step S203; if the successful response is not received, it indicates that the registration has failed, and the process proceeds to step S207.

In step S203, the uniform resource identifier URI returned by the network side is received, and the URI includes number information.

In this step, when the registration is successful, the success response is received, and the success response includes a URI, and the URI includes number information, and the number information is the number information corresponding to the smart card.

In step S204, the mobile subscriber integrated service digital network number MSISDN in the smart card is obtained.

In step S205, it is determined whether the MSISDN and the number information in the URL are the same.

In this step, it is determined whether the number information in the MSISDN and the URL are the same. If not, the process proceeds to step S206; if they are the same, the process proceeds to step S207.

In step S206, the MSISDN is updated according to the number information in the URI.

In step S207, the MSISDN is maintained unchanged.

In this step, when the registration fails, it indicates that the terminal cannot access the network at this time. At this time, the MSISDN is maintained unchanged. Optionally, the operation of registering may be performed after waiting for a certain period of time. When the number information in the MSISDN and the URL are the same, it indicates that the MSISDN in the smart card is already the correct number information. In this case, the MSISDN does not need to be processed, and the MSISDN is maintained unchanged.

FIG. 3 is a flowchart of a third embodiment of an information update method according to an embodiment of the present invention. In the present embodiment, the information update method includes steps S301-S308.

In step S301, a registration request is initiated to the network side.

In step S302, it is determined whether the registration is successful.

In this step, it is determined whether the registration is successful, and whether the registration is successful can be determined by whether a successful response is received. If the successful response is received, it indicates that the registration is successful, and the process proceeds to step S303; if the successful response is not received, it indicates that the registration has failed, and the process proceeds to step S308.

In step S303, the uniform resource identifier URI returned by the network side is received, and the URI includes number information.

In step S304, the data file stored in the smart card is read according to the type of the smart card.

In this step, the data files in the smart card are read according to the type of the smart card. In this embodiment, the smart card type includes a SIM (Subscriber Identity Module) card, a USIM (Universal Subscriber Identity Module) card, and a UIM (User Identify Module) card. For example, operators China Mobile and China Unicom use SIM cards, and China Telecom uses UIM cards. When the types of smart cards are different, the location of the stored data files will vary.

In step S305, the mobile subscriber integrated service digital network number MSISDN is read from the data file.

In this step, the MSISDN is read from the data file. In this embodiment, when the types of smart cards are different, the storage location of the MSISDN in the data file may also be different. When the smart card is a SIM card, the MSISDN is stored in the EF _MSISDN field in the SIM card. At this time, the _MSISDN can be obtained by reading the EF _MSISDN field. Generally, when an existing operator provides a smart card to a user, the number information is not written in the field. Therefore, the field needs to be updated later to view the local number.

In step S306, it is determined whether the MSISDN and the number information in the URL are the same.

In this step, it is determined whether the number information in the MSISDN and the URL are the same. If not, the process proceeds to step S307; if they are the same, the process proceeds to step S308.

In step S307, the MSISDN is updated according to the number information in the URI.

In step S308, the MSISDN is maintained unchanged.

As described above, the information update method in the embodiment of the present invention initiates a registration request to the network side. Receiving the uniform resource identifier returned by the network side when the registration request is successful, acquiring the number information included in the uniform resource identifier, and updating the mobile according to the number information when the number information is inconsistent with the mobile subscriber integrated service digital network number in the smart card. The user integrates the service digital network number, so that the number corresponding to the smart card can be written into the smart card, so that the user does not need to memorize the local number, which is convenient for the user to view and improve the user experience.
