[0015] The detailed description set forth below in conjunction with the accompanying drawings is intended as a description of various configurations and is not intended to represent the only configuration in which the concepts described herein can be practiced. The detailed description includes specific details to provide a comprehensive understanding of the various concepts. However, it is apparent to those skilled in the art that these concepts can be practiced without these specific details. In some cases, well-known structures and components are shown in the form of block diagrams to avoid making such concepts difficult to understand. As described herein, the use of the term "and / or" is intended to represent an "inclusive OR", and the use of the term "or" is intended to represent an "exclusive OR".

[0016] The terms "Subscriber Identity Module", "SIM", "Universal Subscriber Identity Module", "USIM", "User Identity Module", "UIM", "Removable User Identity Module" and "RUIM" are used herein to refer to a memory, which may be an integrated circuit or embedded in a removable card, that stores an International Mobile Subscriber Identity (IMSI), related keys and / or other information used to identify and / or authenticate a wireless device on a network. In some networks (e.g., GSM networks), a SIM may store network-specific information used to authenticate and identify a subscriber on the network, the most important of which are the Integrated Circuit Card Identifier (ICCID), the International Mobile Subscriber Identity (IMSI), the Authentication Key (Ki) and the Local Area Identity (LAI). The SIM may also store other operator-specific data, such as the Short Message Service Center (SMSC) number, the Service Provider Name (SPN), the Service Dialing Number (SDN) and Value Added Service (VAS) applications. In various aspects, the USIM and RUIM may be modules in UMTS and CDMA networks, respectively, that provide equivalent functionality to the SIM in a GSM network. However, the terms "SIM," "USIM," and "RUIM" may be used interchangeably to refer to a general module that is not limited to a specific standard or technology.

[0017] The term "SIM" may also be used as a shorthand reference to a communication network associated with a specific SIM, as the information stored in the SIM enables a wireless device to establish a communication link with a specific network. Thus, the SIM and the communication network, and the services and subscriptions supported by the network, are related to each other.

[0018] The terms "smart card", "SIM card", "Universal Integrated Circuit Card" and "UICC" are used interchangeably to refer to a memory chip or integrated circuit used to provide a SIM, USIM and / or RUIM to a wireless device to store the described provisioning and / or other data. Various UICCs may have storage capabilities ranging from 2 to 3 kilobytes up to 1 gigabyte of information.

[0019] The Universal Integrated Circuit Card (UICC) securely stores the phonebook for users of mobile communication devices such as Mobile Equipment (ME). The UICC can perform a phonebook synchronization procedure in response to a user request to update / delete an existing phonebook entry or to add a new phonebook entry. The user request triggers the UICC to update the Elementary File (EF) change counter (EF CC ), as part of the phonebook synchronization process. Although readable, a problematic UICC can prevent access to the EF CCThe update of the mobile device causes the phonebook synchronization process to fail and prevents the user from adding, updating or deleting phonebook entries. According to aspects of the present disclosure, the modified phonebook update process compensates for a problematic (eg, erroneous) UICC of the mobile device.

[0020] Figure 1 A wireless device 110 is shown, which includes a disclosed update of a phone book within a problematic universal integrated circuit card (UICC) of a mobile equipment (ME). The wireless device 110 communicates with a wireless communication system 120. The wireless device 110 includes a multi-band (e.g., dual-band) concurrent millimeter wave (mmW) transceiver. The wireless communication system 120 may be a 5G system, a long term evolution (LTE) system, a code division multiple access (CDMA) system, a global system for mobile communications (GSM), a wireless local area network (WLAN) system, millimeter wave (mmW) technology, or some other wireless system. The CDMA system may implement Wideband CDMA (WCDMA), Time Division Synchronous CDMA (TD-SCDMA), CDMA2000, or some other version of CDMA. In a millimeter wave (mmW) system, multiple antennas are used for beamforming (e.g., in the range of 30 GHz, 60 GHz, etc.). For simplicity, Figure 1 A wireless communication system 120 is shown that includes two base stations 130 and 132 and a system controller 140. In general, a wireless system may include any number of base stations and any number of network entities.

[0021] The wireless device 110 may be referred to as a mobile equipment (ME), a user equipment (UE), a mobile station, a terminal, an access terminal, a subscriber unit, a station, etc. The wireless device 110 may also be a cellular phone, a smart phone, a tablet computer, a wireless modem, a personal digital assistant (PDA), a handheld device, a laptop computer, a smartbook, a netbook, a cordless phone, a wireless local loop (WLL) station, a Bluetooth device, etc. The wireless device 110 may be capable of communicating with the wireless communication system 120. The wireless device 110 may also be capable of receiving signals from a broadcast station (e.g., the broadcast station 134), signals from satellites in one or more global navigation satellite systems (GNSS) (e.g., satellite 150), etc. The wireless device 110 may support one or more radio technologies for wireless communications such as 5G, LTE, CDMA2000, WCDMA, TD-SCDMA, GSM, 802.11, etc.

[0022] The wireless device 110 may support carrier aggregation, which is an operation on multiple carriers. Carrier aggregation may also be referred to as multi-carrier operation. According to one aspect of the present disclosure, the wireless device 110 may be able to operate in a low frequency band from 698 megahertz (MHz) to 960MHz, a mid-frequency band from 1475MHz to 2170MHz, and / or a high frequency band from 2300MHz to 2690MHz, an ultra-high frequency band from 3400MHz to 3800MHz, and a long term evolution (LTE) in an LTE unlicensed band (LTE-U / LAA) from 5150MHz to 5950MHz. Low frequency band, mid-frequency band, high frequency band, ultra-high frequency band, and LTE-U refer to five groups of frequency bands (or frequency band groups), each of which includes several frequency bands (or simply referred to as "frequency bands"). For example, in some systems, each frequency band can cover up to 200MHz and can include one or more carriers. For example, in LTE, each carrier can cover up to 40MHz. Of course, the range of each frequency band is merely exemplary and non-limiting, and other frequency ranges may be used. LTE Release 11 supports 35 frequency bands, which are referred to as LTE / UMTS bands and are listed in 3GPP TS 36.101. In LTE Release 11, wireless device 110 may be configured with up to five carriers in one or two frequency bands.

[0023] Figure 2 According to one aspect of the present disclosure, Figure 1 The wireless device 110 may include a universal integrated circuit card (UICC) interface 202 that may receive an embedded UICC (eUICC) 204 that stores profiles associated with one or more subscriptions from a network provider.

[0024] The UICC used in various examples may include user account information, an International Mobile Subscriber Identity (IMSI), a set of SIM Application Toolkit (SAT) commands, and storage space for phonebook contacts. The UICC may also store home identifiers (e.g., system identification number (SID) / network identification number (NID) pairs, home preferred list of mobile networks (HPLMN) codes, etc.) to indicate each subscribed network operator provider of the UICC. An integrated circuit card identity (ICCID) SIM serial number may be printed on the UICC for identification. In some aspects, the UICC may be implemented within a portion of the memory of the wireless device 110 (e.g., in the memory 214), and thus no separate or removable circuit, chip, or card is required.

[0025] The wireless device 110 may include at least one controller, such as a general purpose processor 206, which may be coupled to a coder / decoder (CODEC) 208. The CODEC 208, in turn, may be coupled to a speaker 210 and a microphone 212. The general purpose processor 206 may also be coupled to a memory 214. The memory 214 may be a non-transitory computer-readable storage medium that stores processor-executable instructions. The memory 214 may store an operating system (OS) and user application software and executable instructions. The memory 214 may also locally store cached profiles of subscriptions supported by the eUICC 204.

[0026] The general processor 206 and the memory 214 may each be coupled to at least one baseband processor or baseband modem processor 216. The eUICC 204 in the wireless device 110 may utilize one or more baseband-RF resources. The baseband-RF resources may include a baseband modem processor 216, which may perform baseband / modem functions to communicate with a radio access technology (RAT) and control the RAT. The baseband-RF resources may include one or more amplifiers and radios, commonly referred to as radio frequency (RF) resources (e.g., RF resources 218). In some examples, the baseband-RF resources may share a baseband modem processor 216 (e.g., a single device that performs baseband / modem functions for all RATs on the wireless device 110). In other examples, each baseband-RF resource may include a physically or logically separate baseband processor (e.g., BB1, BB2).

[0027] The RF resources 218 may be a transceiver that performs transmit / receive functions for the eUICC 204 on the wireless device 110. The RF resources 218 may include separate transmit and receive circuit systems, or may include a transceiver that combines transmitter and receiver functions. In some examples, the RF resources 218 may include multiple receive circuits. The RF resources 218 may be coupled to a wireless antenna (e.g., wireless antenna 220). The RF resources 218 may also be coupled to the baseband modem processor 216.

[0028] In some examples, the general processor 206, memory 214, baseband modem processor(s) 216, and RF resources 218 may be included in the wireless device 110 as a system-on-chip 250. In some examples, the eUICC 204 and its corresponding communication interface (e.g., UICC interface) may be external to the system-on-chip 250. In addition, various input and output devices may be coupled to components, such as interfaces or controllers, on the system-on-chip 250. Exemplary user input components suitable for use in the wireless device 110 may include, but are not limited to, a keypad 224, a touch screen display 226, and a microphone 212.

[0029] In some examples, keypad 224, touch screen display 226, microphone 212, or a combination thereof may perform the function of receiving a request to initiate an outgoing call or receiving a personal identification number. Interfaces may be provided between various devices and modules to implement functions in wireless device 110 to enable communications in the wireless device.

[0030] The eUICC 204, baseband processors BB1, BB2, RF resources 218, and wireless antennas 220 working together may constitute two or more radio access technologies (RATs). For example, the wireless device 110 may be a communication device including a UICC, a baseband processor, and RF resources, and the RF resources are configured to support two different RATs, such as 5G or LTE and GSM. More RATs may be supported on the wireless device 110 by adding multiple RF resources and antennas for connecting to additional mobile networks.

[0031] In some examples (not shown), the wireless device 110 may include, among other things, additional UICCs or SIM cards, UICC or SIM interfaces, multiple RF resources associated with the additional UICCs or SIM cards, and additional antennas for supporting subscription communications with additional mobile networks.

[0032] The eUICC 204 may support multiple mobile network operator profiles or subscription profiles. For example, a user may download multiple profiles to the eUICC 204. Each profile may store static SIM information that is used to support subscriptions with one or more mobile phone networks. Thus, the eUICC 204 may play the role of multiple SIMs, as each SIM supports one profile.

[0033] In various examples, the wireless device 110 can be configured to locally cache one or more subscription profiles associated with or stored in the UICC. The profiles can be cached in the memory 214, a portion of which can be designated as memory for the modem.

[0034] Figure 3 is a process flow diagram of a method 300 for updating a phonebook within a problematic universal integrated circuit card (UICC) of a mobile equipment (ME) according to aspects of the present disclosure. According to aspects of the present disclosure, a modified phonebook update process compensates for a problematic (eg, erroneous) UICC of a mobile equipment.

[0035] At block 302, a mobile device including a subsystem such as a UICC is powered on. For example, a processor of the mobile device (e.g., a baseband processor) powers on the UICC of the mobile device. At block 304, the processor of the wireless device initiates initialization of a phonebook entry within a phonebook of the UICC. At block 306, a determination is made as to whether a UICC phonebook synchronization value is readable. For example, at block 306, the processor determines whether an elementary file (EF) phonebook (P) synchronization counter (EF PSC ), Elementary File (EF) Unique Identifier (EF UID ), Elementary File (EF) Previous Unique Identifier (EF PUID ) and the elementary file (EF) change counter (EF CC ) is readable.

[0036] When the UICC phonebook synchronization value (such as EF PSC EF UID EF PUID EF CC ) is readable, at box 308, the phonebook synchronization support (pb_sync_supported) flag is set to 'yes'. Otherwise, the control flow branches to box 310, in which the pb_sync_supported flag is set to 'no'. At box 312, a request to add / delete / update (one or more) phonebook contacts is received from the user interface (UI) of the mobile device. At box 320, it is determined whether the pb_sync_supported flag is set to 'yes'. If the pb_sync_supported flag is set to 'yes', then at box 330, the basic file (EF) change counter (EF CC ) is writable. When the basic file (EF) changes the counter (EF CC ) is not writable, an alternative UICC phonebook synchronization process is performed in block 322, and the UICC phone synchronization process of block 332 is skipped in block 322. The control flow proceeds to block 334, in which the speed dialing number (EF) of the elementary file (EF) is synchronized. ADN ) performs a write to execute a request to add / delete / update (one or more) phonebook contacts.

[0037] According to aspects of the present disclosure, a modified phonebook update process is implemented by adding blocks 330 and 322 to compensate for a problematic (e.g., erroneous) UICC of a mobile device. Otherwise, when a request to add / delete / update a phonebook contact is triggered from the UI interface at block 312, the EF CC The binary update command is used to update EF in block 334. ADN Previously, mobile devices would traditionally try to convert EF CC The UICC is updated as the first step of the phonebook synchronization at block 332. Conventionally, the problematic UICC will respond to the EF with a '6982' code ("security status not satisfied"). CC In response to the '6982' code, the mobile device conventionally stops the phone synchronization process and does not write EF in block 334. ADN According to this aspect of the present disclosure, the modified phonebook update process for adding new contacts from the UI interface will not fail.

[0038] In this aspect of the disclosure, it is recognized that if phonebook synchronization is supported by the UICC of the mobile device, then EF CC should be readable and writable. However, in traditional fault conditions, EF CC The erroneous card is readable but not writable. As a result, the problematic UICC does not have the ability to support phonebook synchronization. According to other aspects of the present disclosure, in response to a request to add / modify / delete contacts from a UI interface of the mobile device, a modified phonebook update process provides the mobile device with access to the phonebook resident in the erroneous card.

[0039] Figure 4 A simplified flow chart of a method 400 for updating a phonebook in a problematic universal integrated circuit card (UICC) of a mobile equipment (ME) according to aspects of the present disclosure is depicted. At block 402, in response to a request from a user of the ME to add / delete / update phonebook contacts, an elementary file (EF) change counter (EF) of the UICC of the ME is updated. CC ) is detected as readable but not writable. In block 404, the phonebook synchronization process of the UICC is skipped. In block 406, the abbreviated dialing number (EF) of the basic file (EF) of the UICC is ADN ) performs a write to execute a request to add / delete / update a phonebook contact.

[0040] According to another aspect of the present disclosure, an apparatus for updating a phonebook in a problematic universal integrated circuit card (UICC) of a mobile equipment (ME) is described. The apparatus may include a method for updating an elementary file (EF) change counter (EF) of the UICC of the ME in response to a request from a user of the ME to add / delete / update a phonebook contact. CC ) is detected as a component that can be read but not written. The device may include a component for skipping the phonebook synchronization process of the UICC. The device may include a component for writing an elementary file (EF) abbreviated dialing number (EF) of the UICC ADN ) to execute the request to add / delete / update the phonebook contacts. The detection component, skip component and / or write component may be the baseband modem processor 216, the general processor 206 and / or the memory 214. In another aspect, the above components may be any module or device configured to perform the functions described by the above components.
