Title: Chip-enhanced battery

Description:
FIELD 
     The disclosure relates to a chip-enhanced battery for a machine type communication device (MTC) and a method for using a chip-enhanced battery for communication with a mobile network operator (MNO). Such a smart battery includes a SIM (subscriber identification module) for establishing communication with a mobile network operator (MNO) when the battery is inserted in the MTC. 
     BACKGROUND 
     In future 5G communication systems, voice-related services won&#39;t be the majority of mobile network operator (MNO) services. IoT (Internet of Things) UEs (User Equipments) are tailored for services intended to connect machines to a network with the aim of offering specific data-related services. They are designed to serve as sensors or machine type communication (MTC) units, requesting typically low data rates of a few hundreds of bytes, nonetheless, expecting dense deployment scenarios characterized by a massive presence of such devices over an area and space (one can imagine a multitude of potential applications, i.e., smart cities, defense, agriculture and others). The user and operator expectation is that these devices typically operate under low data rates, and the battery lifetime shall be up to 10 years. Application areas are metering and environment parameter reporting, with a wide range of simple radio interfaces. The challenge for the MNO is to keep control over a skyrocketing number of non-complex devices and to provide the technical means for managing the billing of these simple devices.

     DETAILED DESCRIPTION 
     In the following detailed description, reference is made to the accompanying drawings, which form a part thereof, and in which is shown by way of illustration specific aspects in which the disclosure may be practiced. It is understood that other aspects may be utilized and structural or logical changes may be made without departing from the scope of the present disclosure. The following detailed description, therefore, is not to be taken in a limiting sense, and the scope of the present disclosure is defined by the appended claims. 
     The following terms, abbreviations and notations are used herein:
     IoT: Internet of Things   SIM: Subscriber Identity Module   eSIM: embedded Subscriber Identity Module   MNO: Mobile Network Operator (Network)   MTC: Machine Type Communication   UE: User Equipment,   ID: Identification (code)   QR code: Quick Response code   NFC: Near Field Communication   LED: Light Emitting Diode   3GPP: 3rd Generation Partnership Project,   LTE: Long Term Evolution,   RF: Radio Frequency,   DB: Data Base   

     The methods and devices described herein may be based on chip-enhanced batteries, i.e. smart batteries and methods for using chip-enhanced batteries for establishing communication with a MNO network. It is understood that comments made in connection with a described method may also hold true for a corresponding device configured to perform the method and vice versa. For example, if a specific method step is described, a corresponding device may include a unit to perform the described method step, even if such a unit is not explicitly described or illustrated in the figures. Further, it is understood that the features of the various exemplary aspects described herein may be combined with each other, unless specifically noted otherwise. 
     A battery according to the disclosure is an electric battery, i.e., a device including one or more electrochemical cells with external connections provided to power electrical devices. A discharging battery has a positive terminal, or cathode, and a negative terminal, or anode. The terminal marked negative is the source of electrons that when connected to an external circuit will flow and deliver energy to an external device. When a battery is connected to an external circuit, electrolytes are able to move as ions within, allowing the chemical reactions to be completed at the separate terminals and so deliver energy to the external circuit. It is the movement of those ions within the battery which allows current to flow out of the battery to perform work. 
     The methods and devices described herein may be applied in machine type communication (MTC) devices or machine-to-machine communication (M2M) devices. MTC or M2M communications refer to automated data communications among devices and the underlying data transport infrastructure. The data communications may occur between an MTC device and a server, or directly between two MTC devices. The communications among MTC devices can be handled through different network technologies. Point-to-point and multi-hop wireless networks, such as ad hoc networks, sensor and mesh networks, have been considered as a means to provide Internet access for devices, forming the so-called Internet of Things (IoT). In personal area networks, for instance, IEEE 802.15.x has been developed to serve a variety of applications. IEEE 802.11ah is another technology that supports low-power transmissions with extended coverage range in Wi-Fi networks. 
     The methods and devices described herein may be applied in environments according to the Internet of Things (IoT). They can be implemented with cellular wireless technologies like Sigfox, LoRa and NB-IoT, etc. providing coverage, latency and reliability in extreme dense environments for guaranteeing secure, identifiable and authenticated access to the mobile networks. The subscriber identity module (SIM) is the primary piece of operator supplied user equipment (UE) to access cellular wireless networks, which evolved most recently into embedded SIM (eSIM), fixed in the device and non-removable as well as SIM remote provisioning where a SIM can be updated over the air and is able to store one or more operator profiles. Methods, systems and devices according to the disclosure provide a new affordable scalable system for IoT UEs connected to wireless cellular networks which are combining batteries and eSIM providing a scalable, flexible and most efficient procurement, provisioning, maintenance and billing for millions and billions of IoT UE, as described hereinafter. 
     The methods and devices described herein may be implemented in wireless communication networks, in particular communication networks based on mobile communication standards such as LTE and in particular 5G. The methods and devices described below may be implemented in UEs and MTC devices. The described devices may include integrated circuits and/or passives and may be manufactured according to various technologies. For example, the circuits may be designed as logic integrated circuits, analog integrated circuits, mixed signal integrated circuits, optical circuits, memory circuits and/or integrated passives. 
     The methods and devices described herein may be configured to transmit and/or receive radio signals. Radio signals may be or may include radio frequency signals radiated by a radio transmitting device (or radio transmitter or sender) with a radio frequency lying in a range of about 3 Hz to 300 GHz. The frequency range may correspond to frequencies of alternating current electrical signals used to produce and detect radio waves. 
     The methods and devices described herein after may be designed in accordance to mobile communication standards such as e.g. the ones of the 3rd Generation Partnership Project (3GPP). Long Term Evolution (LTE), LIE-Advanced, LTE-Advanced Pro and the next generation standard are mentioned as representatives for wireless communication of high-speed data for mobile phones, data terminals and MTC devices. 
     The methods and devices described herein may be configured to transmit and/or receive light signals, in particular by using light emitting diodes (LEDs) and photo detectors. A light-emitting diode (LED) is a two-lead semiconductor light source. It is a p-n junction diode, which emits light when activated. When a suitable voltage is applied to the leads, electrons are able to recombine with electron holes within the device, releasing energy in the form of photons. This effect is called electroluminescence, and the color of the light (corresponding to the energy of the photon) is determined by the energy band gap of the semiconductor. Photo sensors or photo detectors are sensors of light or other electromagnetic energy. A photo detector converts light signals that hit the junction into voltage or current. The connection uses an illumination window with an anti-reflect coating to absorb the light photons. This results in creation of electron-hole pairs in the depletion region. Photodiodes and photo transistors are examples of photo detectors, other examples are solar cells as they absorb light and turn it into energy. 
     The methods and devices described herein may be configured to transmit and/or receive radio signals via near field communication (NFC). NFC is a standards-based technology which is used to provide short range wireless connectivity technology carrying secure two-way interactions between electronic devices. Communications are established in a simple way, not requiring set-up by users as in the case of many other wireless communications. NFC near field communication provides contactless communication up to distances of about 4 or 5 centimeters. In this way communication is inherently more secure because devices normally only come into contact and hence communication when the user intends this. As no physical connectors are used with NFC near field communication, the connection is more reliable and does not suffer problems of contact wear, corrosion and dirt experienced by systems using physical connectors. NFC utilizes inductive-coupling, operating within the globally available unlicensed radio frequency ISM band of 13.56 MHz on ISO/IEC 18000-3 air interface at rates ranging from 106 to 424 kbit/s. 
     Systems, devices and methods as described hereinafter may use SIM modules for establishing a communication channel with a mobile network operator. A subscriber identity module or subscriber identification module (SIM) is an integrated circuit chip or a circuit on a microchip that is intended to securely store a unique identification code, e.g. an international mobile subscriber identity (IMSI) number and its related key, which are used to identify and authenticate subscribers on mobile devices (such as the MTC devices described hereinafter or mobile phones or computers). It is also possible to store other data, e.g. contacts etc. A SIM module or SIM card may include its unique serial number (ICCID), international mobile subscriber identity (IMSI) number, security authentication and ciphering information, temporary information related to the local network, a list of the services the user has access to, and two passwords: a personal identification number (PIN) for ordinary use, and a personal unblocking code (PUK) for PIN unlocking. 
     In the following, embodiments are described with reference to the drawings, wherein like reference numerals are generally utilized to refer to like elements throughout. In the following description, for purposes of explanation, numerous specific details are set forth in order to provide a thorough understanding of one or more aspects of embodiments. However, it may be evident to a person skilled in the art that one or more aspects of the embodiments may be practiced with a lesser degree of these specific details. The following description is therefore not to be taken in a limiting sense. The various aspects summarized may be embodied in various forms. The following description shows by way of illustration various combinations and configurations in which the aspects may be practiced. It is understood that the described aspects and/or embodiments are merely examples, and that other aspects and/or embodiments may be utilized and structural and functional modifications may be made without departing from the scope of the present disclosure. 
       FIG. 1  is a schematic diagram illustrating a communication system  100  with a chip-enhanced battery  110 , an MTC device  120  and a MNO network  130  according to an implementation. Multiple such MTC devices  120  can be used in such a communication system  100 . 
     The communication system  100  includes a machine type communication (MTC) device  120  and a mobile network operator (MNO) communication device  130 , i.e. a communication device within a network of the MNO. The MTC device  120  is used to initiate a communication channel  115  with the MNO communication device  130  when the chip-enhanced battery  110  is inserted  114  into the MTC device  120 . 
     The chip-enhanced battery  110  can be applied in a machine type communication (MTC) device  120 . The chip-enhanced battery  110  includes a battery  111  and a microchip  112  integrated with the battery  111 . The microchip  112  includes a subscriber identification module (SIM)  113 , e.g. an embedded SIM module that can be used to initiate a communication channel with the mobile network operator (MNO)  130  responsive to an insertion of the chip-enhanced battery  110  into the MTC device  120 . 
     The MTC device  120  may include a unique identification code representing a pre-paid data service charge. The MTC device  120  may be configured to authenticate the chip-enhanced battery with the MNO based on the unique identification code. 
     The SIM module may be a conventional SIM card with reduced SIM functionality. That is, only basic SIM functions may be implemented, e.g. authentication functions, authorizing functions, billing and/or security functions. The microchip  112  may include a memory to store the unique identification code. The SIM module  113  may read out the unique identification code from the memory and may initiate the communication channel with the MNO based on the unique identification code. In one example, the unique identification code is imprinted on an outside of the chip-enhanced battery. 
     The microchip  112  may be an integral part of the battery  111 , such that disassembling the battery  111  to access the microchip  112  destroys the microchip  112  or at least disables the microchip  112 . The battery  111  may be non-rechargable. The battery  111  may include an internal resistance configured to vary its nominal value responsive to an external recharging process. The chip-enhanced battery  110  may include a disabling circuit configured to disable operation of the microchip  112  based on a deviation of the internal resistance from a threshold value. 
     The battery  111  may include one or more electrochemical cells and may be designed as described below with respect to  FIG. 3 . In one example, the battery  111  may be formed as a coin cell. In one example, the battery may include set of battery cells connected in series. The battery  111  may include a first connector configured to provide the MTC device  120  with a positive supply voltage and a second connector configured to provide the MTC device  120  with a negative supply voltage. 
     The chip-enhanced battery  110  may include two galvanic power supply contacts configured to supply DC power to the MTC device. In one implementation, the microchip  112  may be configured to communicate with the MTC device  120  based on multiplexing a signal to the DC power. The chip-enhanced battery  110  may include one or more electrical contacts. The microchip  112  may communicate with the MTC device  120  by using the at least one electrical contact. 
     In one implementation, the chip-enhanced battery  110  may include a light emitting diode (LED). The microchip  112  may communicate with the MTC device  120  by transmitting light between the LED and a light sensitive sensor comprised in the MTC device  120 . 
     In an alternative implementation, the chip-enhanced battery  110  may include a near field communication (NFC) device. The microchip  112  may communicate with the MTC device  120  by radio communication between the NFC device and another NFC device comprised in the MTC device  120 . 
     The battery  111  may include a compartment configured to mount the microchip. The compartment may mount additional circuitry for providing communication between the microchip  112  and the MTC device  120 , e.g. NFC drivers or circuitry related to light generation. 
     The MTC device  120  may include a modem and a processor, e.g. as described below with respect to  FIG. 2 , for initiating a communication channel with a mobile network operator (MNO). The MTC device  120  may include the chip-enhanced battery  110  when inserted  114  in the MTC device  120 . The SIM module of the chip-enhanced battery  110  may initiate the communication with the MNO upon insertion  114  of the chip-enhanced battery  110  into the MTC device  120 . 
     The MTC device with inserted smart battery  110  may include a unique identification code representing a pre-paid data service charge. The SIM module of the smart battery  110  may authenticate the chip-enhanced battery  110  with the MNO  130  based on the unique identification code. The microchip  112  may include a memory, e.g. a memory  123  as described below with respect to  FIG. 2  for storing the unique identification code. The SIM module  113  may read out the unique identification code from the memory and may initiate the communication with the MNO  130  based on the unique identification code. 
     Of course, the described chip-enhanced battery  110  is not limited to the use in machine type communication devices. For example, such chip-enhanced batteries can also be used in mobile phones, smartphones, tablets etc. for establishing a mobile communication. 
       FIG. 2  is a schematic diagram illustrating a communications system  200  with a chip-enhanced battery  210  connected with an MTC device  120  according to an implementation. The communication system  200  includes a chip enhanced battery  210 , e.g. a chip-enhanced battery  110  as described above with respect to  FIG. 1 , and a MTC device  120  as described above with respect to  FIG. 1 . 
     The chip-enhanced battery  210  is an aggregate device of a battery  111  and a SIM module  113  implemented on a chip which is integrated with the battery  111 . The MTC device  120  includes a processor  122 , a memory  123  and a modem  121 . The processor  122  has a first interface  130  with the memory  123  for storing and reading data to or from the memory  123 . The processor  122  has a second interface  131  with the modem  121  for controlling the modem  121 . A supply line  132  between battery  132  and MTC device  120  is used for supplying the modem  121  and the processor  122  with electrical power. An interface  133  between the SIM module  113  and the modem  121  is used to provide subscriber ID information and/or authentication information to the modem  121 . The modem  121  may initiate a radio communication link with a MNO network controlled by the processor  122 . The memory  123  may be used by the processor  122  to store and retrieve data, e.g. subscription information, charging information and information related to the establishment of the communication link with the MNO network. 
     The MTC device  120 , also referred hereinafter as IoT UE, is comprised of main building blocks wireless cellular modem  121 , processor  122 , memory  123 , SIM or eSIM  113  and battery  111 , where the chip-enhanced battery  210  including the SIM module  113  and the battery  111  can be inserted in and removed from the MTC device  120 . The SIM module  113  can initiate a communication with the MNO. An operator relationship with the MNO and the service of the MNO may be provided pre- or post-paid depending on the contract. Such simple MTC device  120  reduces procuring, provisioning, maintenance and billing costs for the millions and billions of IoT UEs as forecasted. 
     Complex contract provisioning and management is not necessary. The data service can be provided by an eSIM enhanced battery  210  either with a valid MNO pre-paid or post-paid service subscription as long as the battery  210  can supply energy. The user may have different means of configuring such IoT UEs. For instance, if the user wants a sensor to report a set of measured information very frequently, the data volume will increase, leading towards increased power consumption. As a result, transmissions of high data volumes will require a faster replacement of the smart battery  210 . Hence, this way, the system  200  supports a fair low maintenance zero cost business model, since a one-to-one relationship between transfer of data volumes and power consumption is established. 
     The communication system according to the disclosure presents a new affordable scalable system for IoT UEs connected to wireless cellular networks based on a smart battery combining battery and a chip containing eSIM functions, providing a scalable, flexible and most efficient procurement, provisioning, maintenance and billing. The battery  210  includes an eSIM  113  that may be a microchip or a circuit on a microchip, which contains a unique identification code, representing a pre-paid data service charge. The eSIM  113  has not necessarily to have the full functional set of an eSIM, as discussed and intended as full USIM replacement in terminals. This way, end users can purchase the chip-enhanced battery  210 . 
     Implementing such a chip-on-battery technology will set up a relationship to a MNO as information related to the operator is included in the battery  210 . As a consequence, a service provision with the operator can be maintained, until the moment, when battery energy is fully consumed. 
     The solution paves the way for a successful IoT roll out and business model where the cost for connecting to and transmitting data into the cloud will drop to almost zero and the chipset and IoT UE providers as well as network operators will get paid up front and there is no further ongoing cost. 
       FIG. 3  is a schematic diagram illustrating an exemplary chip-enhanced battery  310  according to an implementation. In the example the battery is composed by three cells  111   a ,  111   b ,  111   c , has positive and negative connectors  116   a ,  116   b  and a compartment which contains the chip  112  with the value code. The compartment can also contain additional circuitry for the communication with the MTC device as described before. Of course, the chip-enhanced battery  310  may contain any other number of cells, for example one single cell, two cells, four, five, 10, 15, 20 etc. cells. 
     The chip  112  shall be an integral part of the smart battery  310  and shall not be accessible. The Smart Battery  310  may have unique shapes or sizes, to avoid confusion with conventional batteries. Further different types of IoT devices may require different voltage, thus the combination of cells may vary depending on these requirements. Disassembling the smart battery  310  to access the chip  112  shall destroy the chip  112 . The communication between the chip enhanced battery  310  and the MTC device may be done in various ways, which are described as follows: 
     In a first exemplary implementation, the smart battery  310  has additional galvanic contacts, e.g.  6  for an eSIM, beside the power supply contacts  116   a ,  116   b , being used for a communication between the IoT UE modem/processor and the battery chip  112 . 
     In a second exemplary implementation, the smart battery  310  communicates with the IoT UE modem/processor device by multiplexing a signal to the DC power, which is extracted in the MTC IoT UE modem/processor, e.g. the modem/processor  121 ,  122  as described above with respect to  FIG. 2 . 
     In a third exemplary implementation, the smart battery  310  contains a light emitting diode, and the IoT UE modem/processor  121 ,  122  has got a light sensitive sensor at the battery holder. Hence the communication can be achievable via a short-range, visible light transmission. 
     In a forth exemplary implementation, the smart battery  310  contains an NFC device being used for a communication between the IoT UE modem/processor  121 ,  122  and the battery chip  112 . 
       FIG. 4  is a block diagram illustrating a communication system  400  with elements which are involved in the validation process of a chip-enhanced battery according to an implementation, e.g. a chip-enhanced battery  110 ,  210 ,  310  as described above with respect to  FIGS. 1 to 3 . 
     The battery  110  may be manufactured for specific service providers or mobile network operators. Each battery  110  receives a chip containing a unique code as an eSIM (pre-paid model). The service provider/operator may receive the list of codes for a data base  402 . If the battery  110  is inserted to a device  120 , the code in the battery  110  may be read out and conveyed via the device  120  and the network  401  to the service provider data base  402 . If the code is registered and valid, device  120  is eligible to use the network  401 . The code in the data base  402  may for instance be tagged as “in use”, and cannot be reused again. 
     In an alternative way, the batteries  110  are generic and the battery factory keeps a list of valid codes (post-paid model) in a factory data base (DB)  403 . A device  120  may have a pre-configured relationship with a MNO. The value code and a battery factory ID may be retrieved by the device  120 , and conveyed via the network  401  to an operator data base  402 , this data base  402  may process the battery ID code and contact the factory data base  403  to check if the code is valid. If valid, the factory data base  403  may mark the code as invalid, and operator data base  402  may set the device/battery configuration to valid. 
     In another alternative implementation, the batteries  110  are generic and the battery factory keeps a list of valid codes in the factory DB  403 . The battery  110  may be sold with an imprinted code e.g. a QR code on the outside. The user can register a device  120  with a mobile network operator, by entering the code via a web interface. When the battery  110  is getting inserted, the code may be read out by the device  120 . The operator may check if the device  120  has been registered by a user, and may check validity with the battery factory, as described before. 
       FIG. 5  schematically illustrates an exemplary method  500  for using a chip-enhanced battery for communication with a mobile network operator (MNO) according to an implementation. The chip-enhanced battery, e.g. a chip-enhanced battery  110 ,  210 ,  310  as described above with respect to  FIGS. 1 to 4 , includes a microchip integrated with the battery for communication with the MNO. The microchip includes a subscriber identification module (SIM). 
     The method  500  includes: inserting  501  the chip-enhanced battery into a machine type communication (MTC) device; and initiating  502  a communication channel with the mobile network operator (MNO) responsive to the insertion of the chip-enhanced battery into the MTC device based on a subscriber identification process initiated by the SIM module of the microchip. 
     The method  500  may further include: authenticating the chip-enhanced battery with the MNO based on a unique identification code representing a pre-paid data service charge. The method  500  may further include: checking the unique identification code of the chip-enhanced battery with the MNO; and if the unique identification code is checked as valid, enabling the communication of the MTC device with the MNO. The method  500  may further include: checking an amount of data service charge represented by the unique identification code; and enabling the communication of the MTC device with the MNO if the amount of data service charge exceeds a threshold value. 
     The method  500  may further include: tagging an entry in a data base of the MNO corresponding to the unique identification code as being in use; and locking the entry in the data base of the MNO corresponding to the unique identification code for a reuse. The method  500  may further include: verifying the chip-enhanced battery based on a battery factory identification. The method  500  may further include: looking-up the battery factory identification from a factory data base; and setting the unique identification code as invalid if the battery factory identification is not found in the factory data base. 
     The method  500  may further include: retrieving the unique identification code from a memory of the microchip. The method  500  may further include: scanning the unique identification code from an imprint on an outside of the chip-enhanced battery, wherein the imprint represents the unique identification code. The method  500  may further include: disabling operation of the microchip based on a deviation of an internal resistance of the battery from a threshold value. 
     The method  500  may further include: supplying the MTC device with DC power through two galvanic power supply contacts of the chip-enhanced battery; and communicating with the MTC device based on multiplexing a signal to the DC power. The method  500  may further include: communicating with the MTC device by using at least one electrical contact mounted at the chip-enhanced battery. The method  500  may further include: communicating with the MTC device by transmitting light between a light emitting diode (LED) comprised on the chip-enhanced battery and a light sensitive sensor comprised in the MTC device. The method  500  may further include: communicating with the MTC device by radio communication between a near field communication (NFC) device comprised in the chip-enhanced battery and another NFC device comprised in the MTC device. 
     The microchip as described in this disclosure may be implemented as a Digital Signal Processor (DSP), as a micro-controller or as any other side-processor or hardware circuit on a chip or within an application specific integrated circuit (ASIC). 
     Embodiments described in this disclosure can be implemented in digital electronic circuitry, or in computer hardware, firmware, software, or in combinations thereof, e.g. in available hardware of mobile devices or in new hardware dedicated for processing the methods described herein. 
     The present disclosure also supports a computer program product including computer executable code or computer executable instructions that, when executed, causes at least one computer to execute the performing and computing blocks described herein, in particular the method  500  described above with respect to  FIG. 5 .
