The present disclosure relates to mobile devices and in particular relates to mobile devices having both work and personal applications.
The use of user equipment (UE) or mobile devices, including smartphones, cellphones, laptops, digital pagers, among others, is becoming more prevalent. Many of these UEs have at least one cellular connection which may be used for both circuit switch and packet switch calls. Such cellular connections are usually based on a subscription or pre-paid plan with a cellular provider.
In order to access the cellular provider's network, a smart card such as a universal integrated circuit card (UICC) is typically found on such devices, where the UICC has one or more applications used for subscriber identity verification. Such applications may, for example, include a subscriber identity module (SIM) application or a universal subscriber identity module (USIM) application for the global system for mobile communication (GSM) networks, for a universal mobile telecommunications system (UMTS system) or long term evolution (LTE) system, a code division multiple access (CDMA) subscriber identity module application (CSIM application) for a CDMA 2000 network, a remote-user identity module (RUIM) for a CDMA network, IP multimedia services (IMS) subscriber identity module (SIM) for IMS services, among others. Once authenticated to the network, the user equipment may then exchange voice or data, depending on the subscription with the cellular network.
One trend in the workplace is to bring your own device (BYOD) policy for employers, where employees may bring their own device and be connected to enterprise services on that device. However, allocation of resources and billing for such systems is complex, since it is difficult to distinguish between personal and work phone calls, text messages, and data usage and the associated costs and billing between the two. A similar trend exists for corporate owned and personal enabled (COPE) devices, where employees are issued a corporate device that may be connected to personal services and applications.
The present disclosure will be better understood with reference to the drawings, in which:
The present disclosure provides a method at a user equipment to facilitate activation and splitting of data billing between at least two parties, the method comprising: starting, at the user equipment, a virtual subscriber identity module platform (‘VSP’) service on the user equipment; verifying VSP configuration information with a network server; upon verification, starting a data networking access point name (‘APN’) based on the configuration information on the user equipment; and setting a status indicator on the user equipment to indicate the VSP service is enabled.
The present disclosure further provides a user equipment configured to facilitate activation and splitting of data billing between at least two parties, the user equipment having a processor; and a communications subsystem, wherein the user equipment is configured to: start a virtual subscriber identity module platform (‘VSP’) service on the user equipment; verify VSP configuration information with a network server; upon verification, start a data networking access point name (‘APN’) based on the configuration information on the user equipment; and set a status indicator on the user equipment to indicate the VSP service is enabled.
The present disclosure further provides a non-transitory computer readable medium comprising instructions that, when executed by a processor of a user equipment, are configured to facilitate activation and splitting of data billing between at least two parties, the instructions providing: starting, at the user equipment, a virtual subscriber identity module platform (‘VSP’) service on the user equipment; verifying VSP configuration information with a network server; upon verification, starting a data networking access point name (‘APN’) based on the configuration information on the user equipment; and setting a status indicator on the user equipment to indicate the VSP service is enabled.
Specifically, the present disclosure relates to the addition of one or more identities on a device to allow split billing between such identities. For example, a work and personal plan can be added to a single device, where work phone calls, text messages and data used for work applications may be billed to an employer, whereas personal phone calls, text messages and data usage may be billed to an individual user of the device. However, the present disclosure is not limited to a work and personal split, and the addition of multiple plans to a device is contemplated by the present disclosure. For example, in another embodiment a device may be split between two users and each user may have a separate plan on the device.
In accordance with one embodiment of the present disclosure, multiple billing plans are implemented utilizing a virtual SIM platform (VSP) at a carrier which allows the user to have multiple phone lines in a single SIM in a phone. As used herein, a SIM can be any identity module. Such split allows a user to have voice and data split billing between the work and personal lines.
In accordance with one embodiment of the present disclosure, one issue for data networking over cellular is that resources may need to be allocated for such data networking. However, if such resources are allocated before the service is enabled or activated on a user equipment, a carrier may have internet protocol (IP) and other resources allocated for a phone in their network without having such corresponding service activated. This will cause the carrier to waste resources for devices who do not have such service allocated.
Thus, in accordance with the embodiments of the present disclosure, the cellular data network for work traffic is not activated until the virtual SIM service has been started and verified with the VSP at the carrier network.
Specifically, when an enterprise activates the VSP service on the UE, a VSP daemon on the UE can start a VSP application. The VSP application may do the registration authentication and if successful, the VSP daemon may then start the data networking access point name (APN) based on configuration information stored within the UE. Upon starting the data networking APN, the UE may then send a system indicator that such APN is configured, allowing the carrier then to accept data over such APN.
Conversely, when the service is disabled, such as when the user leaves the services, then the APN may shut down.
Each of the processes for bring up and taking down an APN are described below.
Reference is now made to
In some implementations, a forwarding information base is a data structure that associates destination with communication interface information. Such communication interface information may for example include a physical interface.
A UE may have multiple FIBs (MFIBs). In this case, the UE may route communication based on various criteria. For example, different FIBs may be assigned to different applications. In other cases, different FIBs may be used for different prioritization of shared network resources. For example, one FIB may be associated with a trust domain or perimeter for work applications and may give higher priority to certain interfaces within the FIB. In other cases, different FIBs may prioritize networks by type based on a policy decision made external to the UE, such as by a user, corporation, among others.
In the example of
Each FIB is associated with a communication channel (110a and 110b) from applications (112a and 112b).
Various interfaces, including Wi-Fi 114a, cellular 114b, local area network (LAN) 114c and Bluetooth™ 114d are shown in UE 102.
The Network Stack 107 may receive requests to access the FIB 108a, 108b. If access to the requested FIB 108a, 108b is granted, the FIB 108a, 108b may provide routing information to the Application 112a, 112b from which the request originated. In some cases, the Network Stack 107 may merely receive a communication and determine which FIB 108a, 108b is mapped to the Communication Channel 110a, 110b.
UE 102 may comprise a tablet, mobile device, personal computer, laptop computer, among others. The embodiment of
UE 102 generally includes a processor which controls the overall operation of the device. Processor interacts with device subsystems such as for example a display, memory, auxiliary input/output (I/O) subsystems, serial port, one or more keyboards or keypads, where keyboard or keypad may comprise a physical keyboard or a virtual keyboard or both, one or more speakers, microphone, other communication subsystem such as a short-range communications subsystem, including Bluetooth and near field communications, and any other device subsystems. Serial port could include a USB port or other port.
Memory of UE 102 may be segregated into various modes of operation, sometimes referred to as perimeters, as described below. Such segregation may be physical or logical. Operating system software used by the processor may be stored in such memory. The operating system, specific device applications, or parts thereof, may be temporarily loaded into a volatile memory such as random access memory (RAM).
Applications may be loaded onto the device and associated with a mode of operation (also called a ‘perimeter’) in some cases. In some embodiments, such applications and data for the application may be stored in memory and associated with the perimeter. For example, separate areas of memory may be used to store the applications or data for each perimeter in some embodiments. In other embodiments, applications or data may be encrypted with a key associated with a perimeter and applications or data for a plurality of perimeters may be stored together. Other options are possible.
In the example of
FIBs 108a and 108b may include any parameters, variables, policies, algorithms, instructions, settings or rules for routing communication to at least one of the Public Network 104 or the Enterprise Network 106. For example, the FIB 108a, 108b may map a destination address to a Physical Interface 114a-d, another FIB, another communication channel or others. In general, the FIB 108a, 108b may be any data structure configured to map or otherwise associate a destination address to a Physical Interface 114a-d. However, FIBs 108a, 108b may equally be comprised of any other data structure and still be within the scope of the present disclosure.
In some cases, FIBs 108a, 108b may include or otherwise identify one or more of the following: destination network address (destination; address of the outgoing interface (gateway); state of the route (flag); current number of active uses for the route (refs); count of the number of packets sent using that rough (use); maximum transmission unit (Mtu); physical interface (interface); or others.
The communication channel 110a, 110b can include any software, hardware, firmware or combination thereof configured to route communication from application 112a, 112b to at least one of the public network 104 or the enterprise network 106. For example, the communication channel 110a, 110b may be an inter-process communication (IPC) channel between the application and the network stack configured to determine a physical interface 114a -d to route communication based on the FIB 108a, 108b.
In some implementations, the communication channel 110a, 110b may be one endpoint of a two-way communication link between an application 112a, 112b and an application running in the public network 104 or the enterprise network 106. For example, the communication channel 110a, 110b may be bound to a port number for a physical interface 114a-d so that the transmission control protocol (TCP) layer can identify the application 112a, 112b to which data is destined to be sent. In some cases, an application 112a, 112b may access the same communication channel 110a , 110b for all communications and the communication channel 110a, 110b may switch between accessing the different FIBs 108a, 108b.
The applications 112a, 112b may be any application, program, module, process or software that may execute, change, delete, generate or otherwise manage information, such as business information, according to the present disclosure. For example, the application 112a, 112b may include a notification application, a contacts application, a calendar application, a messaging application or others. Further, while illustrated as internal to UE 102, one or more processes associated with the application 112a, 112b may be stored, references or executed remotely.
In some cases, applications 112a, 112b may be configured to access different perimeters, such as a personal perimeter or an enterprise perimeter.
In connection with determining an interface 114a-d, the application 112a, 112b may execute one or more of the following: determine a FIB 108a, 108b based on MFIBs assigned to the application 112a, 112b; transmit a request for access to a FIB 108a, 108b to the network stack 107; determine a physical interface 114a -d for the destination based on an assigned FIB 108a, 108b; determine whether an assigned FIB 108a, 108b identifies a further FIB 108a, 108b to use to identify the physical interface 114; determine the physical interface 114 to be used based on the destination of a communication and the further FIB 108a, 108b; or others.
UE 102 may include interfaces 114a-d for communication with other computer systems over at least one of the public network 104 or the enterprise network 106 in a client-server or other distributed environment. In certain implementations, the UE 102 receives data form internal or external senders through interfaces 114a-d for local storage, processing or both.
Generally, interfaces 114a-d comprise logic encoded in software, hardware, firmware or a combination thereof operable to communication with at least one of the public network 104 or the enterprise network 106. More specifically, the interfaces 114a-d may comprise software supporting one or more communication protocols associated with the public network 104 or the private or enterprise network 106, or comprise hardware operable to communicate physical signals.
The examples of interfaces 114a-d in
Reference is now made to
Thus, for example, FIB 108a may map or otherwise associate a destination network address to a physical interface 114. As illustrated in the example of
The above device may be used with various networks. Reference is now made to
In the example of
Similarly, policies and data may be pushed from enterprise server 313 to a UE 302 through firewall 311, over secure channel 309 to relay 307, where the policies and data are pushed through firewall 305, over carrier network 303 to a UE 302.
A device that includes both personal and work spaces or applications may interact both with the enterprise servers, such as server 313 and MDS server 315, as well as over carrier network 303 to the internet 320, for example for personal applications.
A module within a network operation center that is carrier controlled is shown in
Utilizing the above architecture, data billings split can be provided in two ways. A first method is to use a dual access point name (APN) in which there are two APNs provided by a carrier. A carrier may then track how much data is utilized on each APN.
In a second embodiment, counters may be used: In this case, the carrier only has one APN but needs to count on the device how much data is sent via the work or personal spaces. While the counter may be used in certain circumstances, the description below will utilize the dual APN process.
In order to support split billing on a device in accordance with the embodiments described below, the device will need to support a VSP service. Once the VSP service is configured for both voice and data, interactions with the network through the carrier may be routed on different interfaces, allowing the carrier to bill the circuit switched or packet switched calls correctly. Specifically, on a VSP device activation, a second data APN can be added along with a work cellular logical interface. Data over the second APN may then be considered work data and billed appropriately.
Reference is now made to
The enterprise server 412 communicates with an enterprise management agent (EMA) 414 on UE 410. Enterprise server 412 may push the previously obtained VSP information to the enterprise management agent 414, as shown by message 430. In one embodiment, an identifier is also pushed to the UE 410. For example, such identifier may be an international mobile subscriber identity (IMSI) created for the virtual SIM.
The enterprise management agent 414 may receive the message 430 from enterprise server 412 and consider this to be a policy of the enterprise and cause actions to be taken on UE 410. Further, enterprise management agent 414 sends acknowledgement message 432 back to the enterprise server 412.
Enterprise management agent 414 may store the persistent objects found within message 430 on the device for future use. For example, enterprise management agent 414 may store VSP information within its own database or in a persistent object store for the enterprise management agent 414.
The carrier policy manager 416 communicates with a database that may be located on an actual SIM within device 410. Such database is shown with reference 418 in the embodiment of
A virtual preload (VPL) of a VSP application may then occur. The virtual preload (VPL) may, in some embodiments, be provided to a user for the user's approval. In particular, as shown in
The carrier information manager 416 may then request, from an application server 422, the VSP service application. Such request is shown by message 440. Application server 422 may be any remote server providing application data to a mobile device (i.e UE 410).
The application server 422 returns the VSP service application, as shown by message 442. Message 442 causes the application to be launched and installed on the device.
The launching may involve several processes. For example, VSP service 424 may, once launched, listen to the enterprise management agent 414 to determine whether the VSP information provided by the enterprise server 412 is okay, as shown by block 444. If yes, then the process may proceed to block 450 in which the VSP application is started.
As used herein, a VSP application is the entity that communicates with the VSP network component for virtual SIM information, including the virtual phone number. The VSP service interfaces with the system to give deep integration into the device. Such VSP service includes the user interface components, SMS, the second APN being brought up, among other functionality.
Referring again to
The second data APN that is added to the enterprise_unsecure FIB may be represented as a logical interface in the system. The new work cellular interface is not secure since it is not pushed from an enterprise server and is over an unsecured carrier network.
The new interface may be assigned a type or label such as “cellular_work”. This type allows the system services that deal directly with interfaces to be able to differentiate personal cellular and work cellular interfaces. In order to support such new interface, a new routing domain or FIB may be added in a multi-FIB device. For example, such new FIB may be considered a “enterprise_unsecure” FIB since it is was pushed by a carrier and is therefore considered by the enterprise to be an unsecure connection.
In this case, secure data may be sent over a separate interface, labelled as “enterprise_secure”. Previously all unsecured communication would go over a personal connection. However, for billing purposes, now an enterprise_unsecure routing domain is provided to allow for certain data communications to be processed over such unsecured communication. The work cellular interface is then added to this FIB and other interfaces such as Wi-Fi or VPN interfaces from the Personal FIB may also be added to the new FIB.
Applications may then be assigned to the new FIB based on a group identifier associated with the application. Specifically, applications are assigned a group ID associated with a FIB. In many cases, an application will have a single group ID associated with a single FIB. However, in some cases hybrid applications or services may access multiple FIBs by having multiple group IDs associated with such application. Further, applications may be hybrid in which case they would permit communications over the enterprise_unsecure FIB or personal FIB.
In some situations, preference may be given to a particular FIB for hybrid applications. Such preference may be utilized, for example, to select a Enterprise FIB first. However, if the Enterprise FIB is overly busy or causes significant delay then a personal FIB may be utilized instead.
After such enterprise_unsecured FIB has been put on to the device, all data traffic that is routed over this FIB may then be accurately captured by the carrier and billed to the enterprise rather than to the personal account of the mobile device holder.
By using multiple routing domains or forward information bases, each perimeter or personality on the device may have its own routing table or domain, its own interface and its own interface priorities. In this case, traffic that proceeds over a personal FIB has different routing in place than traffic over other FIBS. Separate interface priorities allow a default route interface to be different for each FIB. This architecture also adds an extra level of security by not exposing interfaces to other FIBs.
Reference is now made to
UE 512 includes a VSP service 520 and a VSP application 522. A user 524 may in some cases be required to approve the services or activation of the services on the UE 512.
In particular, as seen in
Once notification 540 is received, VSP server 330 may then, optionally, provide verification messages to user 524. These are shown by message 542 providing a text message to user 524 to confirm a PIN. A user confirmation is shown by message 544.
Messages 542 and 544 are optional. In other embodiments, when notification 540 is received by VSP server 330, VSP server 330 may automatically indicate to the VSP application 522 to continue.
In the embodiment of
VSP profile may include the secondary (or virtual) phone number and other information for the device and may be pushed to the device in message 554.
VSP application 522 receives message 554 and stores the VSP profile in a VSP profile database 560. Such storing is shown by message 562.
The VSP application 522 may then provide the VSP profile to the VSP service 520, as shown by message 564. The VSP service 520 may then store the VSP profile as a persistent object in the operating system of the UE 512, shown by message 570. The persistent object store is shown by block 572 in the embodiment of
At this point, the line provider is up, as shown by block 580 and the secondary phone number may be utilized.
In some cases, the VSP profile of message 554 may' be enabled by the enterprise server. In particular, the enterprise server may request certain phone numbers or reserve certain phone numbers and other information from the VSP server 330 to be pushed to UE 512.
The persistent objects within the operating system at block 572 may control the profile for certain uses. For example, the user interface may be changed on the device to allow for the calling from different numbers. Thus, an option may be given to user to phone from a first number from a second number. Further, text messaging or SMS applications may also be provided with two different numbers, and in some cases two different inboxes or application spaces may be provided for such separate SMS numbers. In some cases the first number may be used for a first bill and the second number may be used for a second bill.
Reference is now made to
As seen in
In the embodiment of
Cellular services module 614 receives message 620 and initiates the creation of the interface for the FIB as described above with the network stack 616, as shown by message 622. Message 622 may include information such as the interface, the FIB, and the type label, for example.
Once the persistent object has been stored, an acknowledgement 626 may be provided. The interface is then provided from the cellular service 614 to the VSP service 612, as shown by message 630.
The creation of the interface and the FIB may result in several factors. For data, once the data is enabled over the second APN, certain applications may select connections with the cellular work FIB as needed. For example, a VPN manager may be set to prefer the cellular work interface.
Further, certain device specific connections may also be set to select work cell connections as needed.
Further, enterprise_unsecured FIBs may have the personal cellular interface removed and the work cellular interface added, thereby ensuring that enterprise_unsecured messages are billed to the cellular work bill. Until the service is activated, exiting applications that normally would send enterprise_unsecure traffic would use a personal cellular interface in the enterprise_unsecure FIB to ensure they still have connectivity. In this way, when the VSP service is enabled, the application does not need to change.
While the above describes the creation and setting up of the second phone line and data APN, the device also may have procedures for power up and deletion of the services.
In particular, reference is now made to
If yes, the process of
Once the line is active, the APN information is then checked as shown by block 626 in
The process then proceeds to block 730 in which and the second APN interface is activated.
If any of the steps fail, then the VSP service is disabled and the device may consider that it is waiting for new VSP information from the enterprise server.
If, for example, a new SIM is inserted into the device, the new SIM may also be enabled for VSP. In this case, the enterprise server may also provide any new identifier such as the IMSI and the process as outlined in
In a further embodiment, a VSP service may need to be deleted from a device. Reference is now made to
In this regard, UE 810 communicates with enterprise server 814 using EMA 816 on the UE.
UE 810 further includes VSP service 812.
Enterprise server 814 may send a delete VSP command with information regarding the VSP service to the enterprise management agent 816, as shown by message 820. Enterprise management agent 816 may acknowledge message 820, as shown by message 822.
Enterprise management agent 816 then triggers the VSP service 812 to perform the deletion of the VSP application and settings. In particular, as shown by
The VSP service 812 may then de-activate the second APN interface as shown by arrow 840 and may then delete the VSP profiles, take down line providers, remove the persistent objects in the operating system (including received SMS texts), among other tasks, as shown by block 842.
In one embodiment, the app may not be deleted. In other embodiments, the app may be deleted and may need to be retrieved again upon the device being connected to an enterprise server requiring the VSP services.
In disabling the dual APN data, the VSP service 912 sends a message 920 to the cellular services module 914 to deactivate the second APN interface.
Cellular services module 914 then sends the network stack 916 a message to disconnect the interface FIB and parameters as shown by message 930.
The persistence manager may then acknowledge the message, as shown by message 926.
As will be appreciated,
With the above, the insertion or removal of a SIM may cause the VSP to be activated or deactivated. In particular, the VSP service, upon hot SIM insertion, removes the VSP persistent objects in the operating system and disables the VSP service, removing any state with the second APN if the new SIM inserted does not match with the SIM the service was activated on. This way, if a user pulls the SIM and reinserts it, re-registration is not required and information with not be lost.
A hot SIM insertion would include the power on scenario as described above with regard to
For a single APN, a counter may be introduced on the device. Thus, data travelling over a cellular interface would have a counter to indicate the amount of data that is sent/received for personal versus the amount of data that would be sent/received for work. As will be appreciated by those skilled in the art, for Wi-Fi connection, data counters are not needed since the Wi-Fi connection is not typically billed for data usage.
The data is recorded from device start up and keeps records of all applications that were run until shutdown. These records could then be harvested and reconciled for VSP infrastructure so that carrier billing may be achieved.
In an alternative embodiment to the above, a work device may be adapted to include a personal space. In this case, a bring your own number (BYON) or Corporate Owner Personal Enabled (COPE) scenario may exist in which the physical SIM is related to the work number and the virtual SIM created through the VSP is utilized for the personal services. In this manner, the correct cellular interface may be added to the appropriate FIB for data tracking.
In accordance with the above, one aspect of the present disclosure is the starting of the second APN.
As will be appreciated by those skilled in the art, the carrier configuration that is stored on the device may include APN information related to the SIM. The carrier may insert such information into the SIM when provisioning the device or selling the SIM to the device user. However, it would be ineffective to have all of these APNs reserved for the particular device if the VSP service on the device is not enabled.
Therefore, reference is now made to
From block 1014 the process proceeds to block 1016 in which the VSP service is verified. Such verification may include verifying the IMSI of the device and the PIN as described above.
From block 1016, the process proceeds to block 1020 in which the VSP daemon starts the data networking APN based on the configuration information for the carrier. The process then proceeds to block 1022 in which a system indicator is set indicating that the VSP is configured.
From a carrier perspective, the carrier does not enable or configure the APN until after the data networking APN is started on the UE. In this way, resources at the carrier are not wasted by having preconfigured APNs for devices that may not use them.
The process then proceeds to block 1030 in which a check is made to see whether or not the service has been disabled. If no, the process continues to loop to block 1030.
Conversely, once the service is shut down, the process proceeds to block 1032 in, which the system indicator is set to disable the second APN and the process then proceeds to block 1034 in which the data networking APN is stopped. From block 1034 the process proceeds to block 1040 and ends.
The above therefore provides for split billing between a personal and work space by first starting the VSP service for voice, and once the VSP service for Voice is started, configuring the second data APN between the UE and the carrier.
While the above is described with regards to a work and personal space, the split billing could equally be used for a device having two or more users, where each user has application associated with them. In this way, each user could obtain a bill for the voice and data each uses on the device.
Further, while the above is described with regards to two spaces, in some embodiments more than two APNs and phone numbers could be associated with a device, and more than two bills generated. The startup and shut down procedures for a many identities is similar to that described above with regards to
The above may be implemented on any computing device. If the above is implemented on a user equipment, one example is provided with regard to
UE 1100 may be a two-way wireless communication device having voice and data communication capabilities. Depending on the exact functionality provided, the UE may be referred to as a data messaging device, a two-way pager, a wireless e-mail device, a cellular telephone with data messaging capabilities, a wireless Internet appliance, a wireless device, a mobile device, or a data communication device, as examples.
Where UE 1100 is enabled for two-way communication, it may incorporate a communication subsystem 1111, including both a receiver 1112 and a transmitter 1114, as well as associated components such as one or more antenna elements 1116 and 1118, local oscillators (LOs) 1113, and a processing module such as a digital signal processor (DSP) 1120. Although not shown, communication subsystem 1111 may include additional components. For example, UE 1100 may comprise multiple receivers 1112 and/or transmitters 1114 to allow for simultaneous radio activity. In addition, as will be apparent to those skilled in the field of communications, the particular design of the communication subsystem 1111 will be dependent upon the communication network in which the device is intended to operate.
Network access requirements will also vary depending upon the type of network 1119. In some networks network access is associated with a subscriber or user of UE 1100. A UE may require one or more smart cards which can contain different applications such as a USIM, RUIM or a SIM application in order to operate on a network. The smart card interface 1144 is normally similar to a card-slot into which a smart card can be inserted and ejected. The smart card can have memory and hold many key configurations 1151, and other information 1153 such as identification, and subscriber related information.
When required network registration or activation procedures have been completed, UE 1100 may send and receive communication signals over the network 1119. As illustrated in
Signals received by antenna 1116 through communication network 1119 are input to receiver 1112, which may perform such common receiver functions as signal amplification, frequency down conversion, filtering, channel selection and the like. A/D conversion of a received signal allows more complex communication functions such as demodulation and decoding to be performed in the DSP 1120. In a similar manner, signals to be transmitted are processed, including modulation and encoding for example, by DSP 1120 and input to transmitter 1114 for digital to analog conversion, frequency up conversion, filtering, amplification and transmission over the communication network 1119 via antenna 1118. DSP 1120 not only processes communication signals, but also provides for receiver and transmitter control. For example, the gains applied to communication signals in receiver 1112 and transmitter 1114 may be adaptively controlled through automatic gain control algorithms implemented in DSP 1120.
UE 1100 generally includes a processor 1138 which controls the overall operation of the device. Communication functions, including data and voice communications, are performed through communication subsystem 1111. Processor 1138 also interacts with further device subsystems such as the display 1122, flash memory 1124, random access memory (RAM) 1126, auxiliary input/output (I/O) subsystems 1128, serial port 1130, one or more keyboards or keypads 1132, speaker 1134, microphone 1136, other communication subsystem 1140 such as a short-range communications subsystem and any other device subsystems generally designated as 1142. Serial port 1130 could include a USB port or other port known to those in the art.
Some of the subsystems shown in
Operating system software used by the processor 1138 may be stored in a persistent store such as flash memory 1124, which may instead be a read-only memory (ROM) or similar storage element (not shown). Those skilled in the art will appreciate that the operating system, specific device applications, or parts thereof, may be temporarily loaded into a volatile memory such as RAM 1126. Received communication signals may also be stored in RAM 1126.
As shown, flash memory 1124 can be segregated into different areas for both computer programs 1158 and program data storage 1150, 1152, 1154 and 1156. These different storage types indicate that each program can allocate a portion of flash memory 1124 for their own data storage requirements. Processor 1138, in addition to its operating system functions, may enable execution of software applications on the mobile device. A predetermined set of applications that control basic operations, including at least data and voice communication applications for example, will normally be installed on UE 1100 during manufacturing. Other applications could be installed subsequently or dynamically.
Applications and software may be stored on any computer readable storage medium. The computer readable storage medium may be a tangible or in transitory/non-transitory medium such as optical (e.g., CD, DVD, etc.), magnetic (e.g., tape) or other memory known in the art.
One software application may be a personal information manager (PIM) application having the ability to organize and manage data items relating to the user of the UE such as, but not limited to, e-mail, calendar events, voice mails, appointments, and task items. Naturally, one or more memory stores would be available on the UE to facilitate storage of PIM data items. Such PIM application may have the ability to send and receive data items, via the wireless network 1119. Further applications may also be loaded onto the UE 1100 through the network 1119, an auxiliary I/O subsystem 1128, serial port 1130, short-range communications subsystem 1140 or any other suitable subsystem 1142, and installed by a user in the RAM 1126 or a non-volatile store (not shown) for execution by the processor 1138. Such flexibility in application installation increases the functionality of the device and may provide enhanced on-device functions, communication-related functions, or both. For example, secure communication applications may enable electronic commerce functions and other such financial transactions to be performed using the UE 1100.
In a data communication mode, a received signal such as a text message or web page download will be processed by the communication subsystem 1111 and input to the processor 1138, which may further process the received signal for output to the display 1122, or alternatively to an auxiliary I/O device 1128.
A user of UE 1100 may also compose data items such as email messages for example, using the keyboard 1132, which may be a complete alphanumeric keyboard or telephone-type keypad, whether virtual or real, among others, in conjunction with the display 1122 and possibly an auxiliary I/O device 1128. Such composed items may then be transmitted over a communication network through the communication subsystem 1111.
For voice communications, overall operation of UE 1100 is similar, except that received signals would typically be output to a speaker 1134 and signals for transmission would be generated by a microphone 1136. Alternative voice or audio I/O subsystems, such as a voice message recording subsystem, may also be implemented on UE 1100. Although voice or audio signal output is generally accomplished primarily through the speaker 1134, display 1122 may also be used to provide an indication of the identity of a calling party, the duration of a voice call, or other voice call related information for example.
Serial port 1130 in
Other communications subsystems 1140, such as a short-range communications subsystem, is a further optional component which may provide for communication between UE 1100 and different systems or devices, which need not necessarily be similar devices. For example, the subsystem 1140 may include an infrared device and associated circuits and components or a Bluetooth™ communication module to provide for communication with similarly enabled systems and devices. Subsystem 1140 may further include non-cellular communications such as Wi-Fi or WiMAX.
