Dynamically switching user equipment categories for adaptive mobile communications

## Abstract

Concepts and technologies disclosed herein are directed to dynamically switching user equipment (“UE”) categories for adaptive mobile communications. According to one aspect of the concepts and technologies disclosed herein, a connected car device can determine whether it is operating in an idle mode or a connected mode. Based upon whether the connected car device is operating in the idle mode or the connected mode, the connected car device can determine an active UE category from a set of available UE categories. The connected car device can send the active user equipment category to a base station.

## Background
BACKGROUND
Wireless network service providers, also known as mobile network operators, have been enjoying extensive growth in network user population and subscriptions. The majority of user equipment (“UE”) operating on mobile networks are mobile devices such as basic phones, smartphones, tablets, and the like. Mobile network operators utilize UE category information to allow radio access components, such as eNodeBs (“eNBs”) to communicate effectively with all UEs connected thereto. Currently, the UE categories defined in Third Generation Partnership Project (“3GPP”) Release 12 Technical Specification 36.306 are based upon a combined uplink and downlink capability.
New, non-traditional device types are now emerging, particularly with the growing interest in machine-to-machine (“M2M”) devices and the Internet of Things (“IoT”). It is becoming increasingly challenging for mobile network operators to service effectively the variety of device types and sheer number of devices that, within the next few years, likely will increase to several billion devices worldwide. Moreover, non-traditional device types will likely have distinctly divergent characteristics, including, for example, mobility characteristics (e.g., low, medium, or high mobility), bit rate characteristics (e.g., low, medium, or high bit rate), transmission frequency (e.g., hourly, daily, monthly, or upon request), transceiver characteristics, antenna characteristic, and the like. Non-traditional device types also will likely have distinctly divergent requirements, including bandwidth requirements, delay requirements, jitter requirements, battery life requirements, and the like. These divergent characteristics and divergent requirements will require different treatment by mobile network operators.
SUMMARY
Concepts and technologies described herein relate to dynamically switching UE categories for adaptive mobile communications. According to one aspect of the concepts and technologies disclosed herein, a connected car device can determine whether it is operating in an idle mode or a connected mode. Based upon whether the connected car device is operating in the idle mode or the connected mode, the connected car device can determine an active UE category from a set of available UE categories. The connected car device can send the active user equipment category to a base station.
In some embodiments, when in idle mode, the connected car device can select a lowest available UE category in the set of available UE categories. The lowest available UE category can include, for example, a 3GPP category 0, a 3GPP category 1, a 3GPP category M, or any other lower category that may be proposed in the 3GPP standards.
In some embodiments, when in connected mode, the connected car device can select a highest available UE category in the set of available UE categories. The highest available UE category can include, for example, a 3GPP category 12.
In some embodiments, the connected car device can, when in the connected mode, determine an application communication requirement of a connected car application. In these embodiments, determining the active user equipment category for the connected car device from the set of available user equipment categories is further based upon the application communication requirement.
In some embodiments, the connected car device can, when in the connected mode, determine a mobility state of the connected car device. In these embodiments, determining the active user equipment category for the connected car device from the set of available user equipment categories is further based upon the mobility state.

Moreover, those skilled in the art will appreciate that the subject matter described herein may be practiced with other computer systems, including hand-held devices, M2M devices, wireless devices, multiprocessor systems, distributed computing systems, microprocessor-based or programmable consumer electronics, minicomputers, mainframe computers, routers, switches, other computing devices described herein, and the like.
In the following detailed description, references are made to the accompanying drawings that form a part hereof, and in which are shown by way of illustration specific embodiments or examples. Referring now to the drawings, in which like numerals represent like elements throughout the several figures, aspects of dynamically switching UE categories for adaptive mobile communications will be presented.
Referring now to FIG. 1, aspects of an illustrative operating environment 100 for various concepts disclosed herein will be described. It should be understood that the operating environment 100 and the various components thereof have been greatly simplified for purposes of discussion. Accordingly, additional or alternative components of the operating environment 100 can be made available without departing from the embodiments described herein.
The operating environment 100 shown in FIG. 1 includes a connected car device 102 operating in a vehicle 104. The connected car device 102, as used herein, is a device capable of communication with a radio access network (“RAN”) 106 for voice and/or data communications in accordance with one or more mobile telecommunications standards disclosed herein in support, at least in part, of a connected car, such as, but not limited to, navigation, entertainment, remote access (e.g., remote door lock/unlock, remote vehicle tracking, theft alerts, and the like), safety, vehicle management, fleet vehicle management, vehicle maintenance service (e.g., dealer and/or server center interface), and the like. In the illustrated embodiment, the RAN 106 operates in accordance with Long-Term Evolution (“LTE”), although those skilled in the art will appreciated the applicability of the concepts and technologies disclosed to other mobile telecommunications standards.
The connected car device 102 can be independent of the vehicle 104 or can be integrated within the vehicle 104. In some embodiments, the connected car device 102 is integrated within the vehicle 104, such as part of a vehicle entertainment system (not shown; also commonly referred to as “infotainment system”), a vehicle navigation system, a vehicle engine control unit (“ECU”), and/or another computing system of the vehicle 104. The connected car device 102 can be retrofitted into the vehicle 104 as aftermarket equipment or can be made available as standard or optional original equipment manufacturer (“OEM”) equipment of the vehicle 104. In some embodiments, the connected car device 102 is independent of and configured to communicate with the vehicle 104 via a wired connection, such as, but not limited to, universal serial bus (“USB”), or via a wireless connection, such as, but not limited to, BLUETOOTH.
The vehicle 104 can be a car, truck, van, motorcycle, moped, go-kart, golf cart, or any other ground-based vehicle configured to transport one or more passengers and/or cargo. The vehicle 104 can include other vehicles such as boats, airplanes, helicopters, and the like. As such, the vehicle 104 embodied as a car in the description of the concepts and technologies disclosed herein is merely illustrative, and therefore should not be construed as being limiting in any way.
Although the illustrated embodiment is of a connected car device 102, other M2M devices that might form, at least in part, an IoT network (not shown) are contemplated. IoT is a concept of making physical objects, collectively “things,” also referred to herein as M2M devices, network addressable to facilitate interconnectivity for the exchange of data. As such, M2M devices can be or can include any “thing” that is configured to be network addressable so as to connect to and communicate with one or more networks, such as the RAN 106, over which to communicate with other connected devices, including, for example, computers, smartphones, tablets, vehicles, other M2M devices, combinations thereof, and the like. Moreover, M2M devices can be deployed for consumer use, business use, and can find application in many industry-specific use cases. For example, M2M devices may find at least partial application in the following industries: automotive as in the illustrated embodiment using the connected car device 102; energy; healthcare; industrial; retail; and smart buildings/homes. Those skilled in the art will appreciate the applicability of M2M-solutions to other industries as well as consumer and business use cases. For this reason, the applications of M2M devices described herein are used merely to illustrate some example application of M2M devices, and therefore should not be construed as being limiting in any way.
The RAN 106, can include one or more service areas (which may also be referred to herein as “cells”) having the same or different cell sizes, which may be represented by different cell-types. As used herein, a “cell” refers to a geographical area that is served by one or more base stations operating within an access network. The cells within the RAN 106 can include the same or different cell sizes, which may be represented by different cell-types. A cell-type can be associated with certain dimensional characteristics that define the effective radio range of a cell. Cell-types can include, but are not limited to, a macro cell-type, a metro cell-type, a femto cell-type, a pico cell-type, a micro cell-type, wireless local area network (“WLAN”) cell-type, a MSMC cell-type, and a white space network cell-type. For ease of explanation, a “small cell” cell-type is utilized herein to collectively refer to a group of cell-types that includes femto cell-type (e.g., home eNode-B), pico cell-type, and micro cell-type, in general contrast to a macro cell-type, which offers a larger coverage area. Other cell-types, including proprietary cell-types and temporary cell-types are also contemplated. Although in the illustrated example the connected car device 102 is shown as being in communication with one RAN (i.e., the RAN 106), the connected car device 102 may be in communication with any number of access networks, including networks that incorporate collocated WWAN WI-FI and cellular technologies, and as such, the connected car device 102 can be a dual-mode device.
As used herein, a “base station” refers to a radio receiver and/or transmitter (collectively, transceiver) that is/are configured to provide a radio/air interface over which one or more M2M devices, such as the connected car device 102, can connect to a network. Accordingly, a base station is intended to encompass one or more base transceiver stations (“BTSs”), one or more NodeBs, one or more eNodeBs (“eNBs”), one or more home eNBs, one or more wireless access points (“APs”), one or more multi-standard metro cell (“MSMC”) nodes, and/or other networking nodes or combinations thereof that are capable of providing a radio/air interface regardless of the technologies utilized to do so. A base station can be in communication with one or more antennas (not shown), each of which may be configured in accordance with any antenna design specifications to provide a physical interface for receiving and transmitting radio waves to and from one or more devices, such as the connected car device 102. In the illustrated embodiment, the RAN 106 includes an eNB 108. The eNB 108 is capable of communicating with the connected car device 102 and one or more other devices (not shown).
The RAN 106 might operate in accordance with one or more mobile telecommunications standards including, but not limited to, Global System for Mobile communications (“GSM”), Code Division Multiple Access (“CDMA”) ONE, CDMA2000, Universal Mobile Telecommunications System (“UMTS”), LTE, Worldwide Interoperability for Microwave Access (“WiMAX”), other current 3GPP cellular technologies, other future 3GPP cellular technologies, combinations thereof, and/or the like. The RAN 106 can utilize various channel access methods (which may or may not be used by the aforementioned standards), including, but not limited to, Time Division Multiple Access (“TDMA”), Frequency Division Multiple Access (“FDMA”), CDMA, wideband CDMA (“W-CDMA”), Orthogonal Frequency Division Multiplexing (“OFDM”), Single-Carrier FDMA (“SC-FDMA”), Space Division Multiple Access (“SDMA”), and the like to provide a radio/air interface to the connected car device 102. Data communications can be provided in part by the RAN 106 using General Packet Radio Service (“GPRS”), Enhanced Data rates for Global Evolution (“EDGE”), the High-Speed Packet Access (“HSPA”) protocol family including High-Speed Downlink Packet Access (“HSDPA”), Enhanced Uplink (“EUL”) or otherwise termed High-Speed Uplink Packet Access (“HSUPA”), Evolved HSPA (“HSPA+”), LTE, and/or various other current and future wireless data access technologies. Moreover, the RAN 106 may be a GSM RAN (“GRAN”), a GSM EDGE RAN (“GERAN”), a UMTS Terrestrial Radio Access Network (“UTRAN”), an evolved U-TRAN (“E-UTRAN”), any combination thereof, and/or the like. The concepts and technologies disclosed herein will be described in context of an LTE environment, although those skilled in the art will appreciate the applicability of the concepts and technologies disclosed herein to other cellular technologies, including, in particular, those captured within future generation 3GPP standards.
The RAN 106 is shown as being in communication with an evolved packet core (“EPC”) network 110. The illustrated EPC network 110 includes a mobility management entity (“MME”) 112, a combination serving gateway (“SGW”) and packet data networks (“PDN”) gateways (“PGW”) (“S/PGW”) 114, and a home subscriber server (“HSS”) 116. The EPC network 110 can include other network elements not shown in the illustrated embodiment. As such, the illustrated embodiment should not be construed as being limiting in any way.
The MME 112 controls signaling related to mobility and security for E-UTRAN (e.g., the RAN 106) access by the connected car device 102 and other devices (not shown). The SGW portion of the S/PGW 114 provides a point of interconnect between the radio-side (e.g., the RAN 106) and the EPC network 110. An SGW serves the connected car device 102 (and other UEs not shown) by routing incoming and outgoing IP packets. The PGW portion of the S/PGW 114 interconnects the EPC network 110 and one or more external IP networks, such as, in the illustrated embodiment, a PDN 120. A PGW routes IP packets to and from the PDN 120. A PGW also performs operations such as IP address/IP prefix allocation, policy control, and charging. In some implementations, a PGW and an SGW are deployed as independent network components rather than being combined as in the illustrated embodiment. The HSS 116 is a database that contains user/subscriber information. The HSS 116 also performs operations to support mobility management, call and session setup, user authentication, and access authorization.
The illustrated MME 112 includes a set of UE categories 118 (“UE categories 118”). The UE categories 118 are utilized by the MME 112 to inform eNBs, such as the eNB 108, to effectively communicate with UEs, such as the connected car device 102, based on performance requirements. The MME 112 can send the UE categories 118 to the eNB 108 (and other eNBs not shown) so that the eNB 108 can communicate correctly with the connected car device 102 as well as other UEs, such as mobile phones, tablets, and the like (also not shown).
In accordance with the concepts and technologies disclosed herein, the UE categories 118 can include UE categories defined in 3GPP Release 12 Technical Specification 36.306—specifically, in tables 4.1-1 through 4.1.5. Some of the most common and widely used UE categories in 3GPP are category 3 and category 4. There are other UE categories defined by 3GPP standards and could be used by mobile service providers in commercial network deployments depending on specific application/service roll out requirements. It is contemplated that the UE categories 118 can be updated to include other UE categories described in future 3GPP Releases.
In each of the UE categories 118, there are several parameters that define UE-specific performance, most noticeably the combined downlink and uplink data throughput capability. UE categories, such as category 0, are defined by 3GPP specifically for low power and low data rate applications such as M2M/IoT devices. The data bandwidth supported by such UE categories depends upon LTE modem complexity and chipset implementation capabilities to be able to process specific channel bandwidths. Millions of M2M capable wireless devices targeted for global connectivity over LTE networks might need low power and low bandwidth UE category requirements to maintain a significantly low cost chipset/modem complexity with extended battery life to drive down a large scale cost-effective adoption model across various industry verticals.
In accordance with the concepts and technologies disclosed herein, certain classes of M2M devices, such as a connected car class to which the connected car device 102 belongs, can utilize a UE category management application 122 to change an active UE category 124 from a set of available UE categories (“available UE categories”) 126 to another UE category of the available UE categories 126 based upon various criteria. This criteria can include UE mode (i.e., connected mode or idle mode, an example of which is described below with reference to FIG. 3), one or more application communication requirements of a connected car application 128 (an example of which is described below with reference to FIG. 4), a mobility state 130 of the connected car device 102 (an example of which is described below with reference to FIG. 5), or some combination thereof. The UE category management application 122 can switch dynamically between any of the available UE categories 126. For example, the UE category management application 122 can change the active UE category 124 of the connected car device 102 from a highest available UE category of the available UE categories 126, such as, for example, 3GPP-defined category 12, when the connected car device 102 is operating in a connected mode, and can change to a lowest available UE category of the available UE categories 126, such as, for example, a 3GPP category 0, a 3GPP category 1, a 3GPP category M, or any other lower category that may be proposed in 3GPP standards, when the connected car device 102 is operating in an idle. The UE category management application 122 can change the active UE category 124 based upon other criteria described above.
The connected car application 128 can include any application executable by the connected car device 102 to exchange data via a network, such as the RAN 106 and the EPC 110, in support of one or more M2M services. In some embodiments, the connected car application 128 is configured to communicate with an M2M application server 132 that provides, at least in part, one or more of the M2M services described above. In some embodiments, the connected car application 128 is configured to communicate with one or more external applications/services 134 that provide, at least in part, one or more of the M2M services described above.
The mobility state 130 can include the speed at which the connected car device 102 is currently moving, a movement pattern of the connected car device 102, and/or any other information associated with movement or non-movement of the connected car device 102. The mobility state 130 can be obtained by an accelerometer, global positioning system (“GPS”) component, other motion sensor or component of the connected car device 102, or some combination thereof (best shown in FIG. 8). The mobility state 130 can be utilized by the UE category management application 122 to determine the UE category from the available UE categories 126 appropriate for the connected car device 102 given the movement or non-movement of the connected car device 102. The UE category management application 122 can determine if the connected car device 102 is mobile as described by the above procedures (e.g., speed, serving signal strength, Doppler, and/or the like) and enforce a suitable category selection (e.g., select a higher UE category, such as UE category 11, based upon high-definition multi-channel video streaming application and high-speed mobility needs and dynamically alter such selection mechanism based on a combination of application, mobility patterns, connectivity state, and the like) to receive the best performance for a given application.
The M2M application server 132 can be configured in accordance with European Telecommunication Standards Institute (“ETSI”) and/or 3GPP standards to provide, at least in part, one or more M2M services. In the illustrated embodiment, the M2M application server 132 is shown external to the EPC 110 and in communication with the MME 112 through a firewall 136. In some other embodiments, the M2M application server 132 can be implemented within the EPC network 110.
In the illustrated embodiment, the connected car device 102 can communicate to the MME 112 a UE capability information element 138 when the connected car device 102 attaches to the MME 112. The UE capability information element 138 can include the active UE category 124 and a UE category switching capability 140 indicative of the connected car device's 102 capability of switching among the available UE categories 126 at the discretion of the UE category management application 122. Moreover, when the UE category management application 122 changes the active UE category 124, the connected car device 102 can generate and send the UE capability information element 138 to the M2M application server 132 via the RAN 106 and the EPC 110. The M2M application server 132, in response, can trigger a push request for data transfer to the connected car device 102 based upon the type/amount of data to be transferred to and/or obtained from the connected car device 102.
The UE capability information element 138 can be relayed directly to the M2M application server 132 either directly or indirectly depending on the amount of data being used. The direct signaling interface between the MME 112 and the M2M application server 132 can facilitate efficient low bandwidth connected car specific communications as opposed to establishing a packet data connection via the SGW/PGW 114 and traversing through the IP network.
Low bandwidth, fast data transmission could be achieved using control plane signaling for the connected car device 102 on-demand. For high-speed data transmission, such as for infotainment and location-based services, the connected car device 102 can establish packet data connections over IP network using specific access point name(s) (“APNs”) to be able to receive such services. Data transmission, in this case, occurs from the M2M application server 132 to the connected car device 102 via the PDN 120.
It should be understood that some implementations of the operating environment 100 include multiple connected car devices 102, multiple vehicles, multiple RANs 106, multiple eNBs 108, multiple EPC networks 110, multiple MMEs 112, multiple SGW/PGWs 114, multiple HSSs 116, multiple sets of UE categories 118, multiple PDNs 120, multiple UE category management applications 122, multiple connected car applications 128, multiple mobility states 130, multiple M2M application servers 132, multiple firewalls 136, multiple UE capability information elements 138, or some combination thereof. Thus, the illustrated embodiment should be understood as being illustrative, and should not be construed as being limiting in any way.

In the illustrated example, the connected car device 102 provides the UE capability information element 138 when the connected car device 102 attaches to the MME 112. The UE capability information element 138 can include the active UE category 124 and the UE category switching capability 140 indicative of the connected car device's 102 capability of switching among the available UE categories 126 at the discretion of the UE category management application 122. Moreover, when the UE category management application 122 changes the active UE category 124, the connected car device 102 can generate and send the UE capability information element 138 to the M2M application server 132 via the RAN 106 and the EPC 110 (best shown in FIG. 1). The M2M application server 132, in response, can trigger a push request for data transfer to the connected car device 102 based upon the type/amount of data to be transferred to and/or obtained from the connected car device 102.
Turning now to FIG. 3, a flow diagram illustrating aspects of a method 300 for determining the active UE category 124, such as one of the available UE categories 126, for connected and idle modes of the connected car device 102, will be described, according to an illustrative embodiment. It should be understood that the operations of the methods disclosed herein are not necessarily presented in any particular order and that performance of some or all of the operations in an alternative order(s) is possible and is contemplated. The operations have been presented in the demonstrated order for ease of description and illustration. Operations may be added, omitted, and/or performed simultaneously, without departing from the scope of the concepts and technologies disclosed herein.
It also should be understood that the methods disclosed herein can be ended at any time and need not be performed in its entirety. Some or all operations of the methods, and/or substantially equivalent operations, can be performed by execution of computer-readable instructions included on a computer storage media, as defined herein. The term “computer-readable instructions,” and variants thereof, as used herein, is used expansively to include routines, applications, application modules, program modules, programs, components, data structures, algorithms, and the like. Computer-readable instructions can be implemented on various system configurations including single-processor or multiprocessor systems or devices, minicomputers, mainframe computers, personal computers, hand-held computing devices, microprocessor-based, programmable consumer electronics, combinations thereof, and the like.
Thus, it should be appreciated that the logical operations described herein are implemented (1) as a sequence of computer implemented acts or program modules running on a computing system and/or (2) as interconnected machine logic circuits or circuit modules within the computing system. The implementation is a matter of choice dependent on the performance and other requirements of the computing system. Accordingly, the logical operations described herein are referred to variously as states, operations, structural devices, acts, or modules. These states, operations, structural devices, acts, and modules may be implemented in software, in firmware, in special purpose digital logic, and any combination thereof. As used herein, the phrase “cause a processor to perform operations” and variants thereof is used to refer to causing one or more processors of the connected car device 102, the eNB 108, the MME 112, the S/PGW 114, the HSS 116, and/or one or more other computing systems and/or devices disclosed herein to perform operations.
For purposes of illustrating and describing some of the concepts of the present disclosure, the methods disclosed herein are described as being performed, in part, by the connected car device 102, the eNB 108, the MME 112, the S/PGW 114, the HSS 116, or some combination thereof, via execution of one or more software modules. It should be understood that additional and/or alternative devices and/or network nodes can provide the functionality described herein via execution of one or more modules, applications, and/or other software. Thus, the illustrated embodiments are illustrative, and should not be viewed as being limiting in any way.
The method 300 will be described with reference to FIG. 3 and further reference to FIGS. 1 and 2. The method 300 will be described as being performed by the connected car device 102. The method 300 begins and proceeds to operation 302, where the connected car device 102 attaches to the RAN 106 via one or more eNBs, such as the eNB 108.
From operation 302, the method proceeds to operation 304, where the connected car device 102 determines whether idle mode or connected mode is currently active. The connected car device 102 is in connected mode when the connected car device 102 has at least one radio bearer established. The connected car device 102 is in idle mode when the connected car device 102 has no radio bearers established. The determination at operation 304 can include determining whether an inactivity timer expired, indicating the connected car device 102 is in idle mode or is expected to transition to idle mode.
As used herein, “idle mode” refers to a UE mode in which a UE, such as the connected car device 102, operates in accordance with idle mode procedures defined by 3GPP. As used herein, “connected mode” refers to a UE mode in which a UE, such as the connected car device 102, operates in accordance with connected mode procedures defined by 3GPP.
In response to determining that idle mode is currently active, the method 300 proceeds to operation 306, where the connected car device 102 determines a UE category appropriate for idle mode. In response to determining that connected mode is currently active, the method 300 instead proceeds to operation 308, where the connected car device 102 determines a UE category appropriate for connected mode. For example, the connected car device 102 can execute, via the connected car processor(s) 200, the UE category management application 122 to change the active UE category 124 of the connected car device 102 to a highest available UE category of the available UE categories 126, such as, for example, 3GPP-defined category 12, when the connected car device 102 is operating in connected mode, and can change to a lowest available UE category of the available UE categories 126, such as, for example, a 3GPP category 0, a 3GPP category 1, a 3GPP category M, or any other lower category that may be proposed in 3GPP standards, when the connected car device 102 is operating in idle mode.
From operation 306 or operation 308, the method 300 proceeds to operation 310, where the connected car device 102 sends the UE category (i.e., the new active UE category) determined at either operation 306 or operation 308 to the eNB 108. From operation 310, the method 300 proceeds to operation 312, where the connected car device 102 communicates with the eNB 108 in accordance with the UE category. From operation 312, the method 300 proceeds operation 314, where the method 300 ends.
Turning now to FIG. 4, a method 400 for determining the active UE category 124 for the connected car device 102 based upon application communication requirements will be described, according to an illustrative embodiment of the concepts and technologies disclosed herein. The method 400 can be performed as operations performed at operation 308 described herein above with reference to FIG. 3.
The method 400 will be described with reference to FIG. 4 and further reference to FIGS. 1 and 2. The method 400 will be described as being performed by the connected car device 102. The method 400 begins and proceeds to operation 402, where the connected car device 102 determines one or more application communication requirements of the connected car application 128 executing on or to be executed on (e.g., one or more operations scheduled in memory such as the connected car memory component 202) the connected car device 102. Examples of communication applications include, but are not limited to, voice call, video call, conferencing, IP messaging, texting, on-demand broadcast audio/video streaming, emergency updates, and the like, each having unique requirements for quality. From operation 402, the method 400 proceeds to operation 404, where the connected car device 102 determines an appropriate UE category based upon the application communication requirement(s). From operation 404, the method 400 proceeds to operation 406, where the connected car device 102 sends the appropriate UE category determined at operation 404 to the eNB 108. From operation 406, the method 400 proceeds to operation 408, where the connected car device 102 communicates with the eNB 108 in accordance with the appropriate UE category.
From operation 408, the method 400 proceeds to operation 410, where connected car device 102 determines whether there has been a change to the application communication requirement(s). A change to the application communication requirement(s) can be a change of communication requirements within the same application or a change instigated by additional applications. If the connected car device 102 determines that there has been a change to the application communication requirement(s), the method 400 returns to operation 402. If, however, the connected car device 102 determines that there has not been a change to the application communication requirement(s), the method 400 proceeds to operation 412, where the connected car device 102 determines whether it is still operating in connected mode. If the connected car device 102 is still operating in connected mode, the method 400 returns to operation 408. If, however the connected car device 102 is not still operating in connected mode, the method 400 proceeds to operation 414, where the method 400 ends.
Turning now to FIG. 5, a flow diagram illustrating aspects of a method 500 for determining the active UE category 124 for the connected car device 102 based upon the mobility state 130 of the connected car device 102 will be described, according to an illustrative embodiment of the concepts and technologies disclosed herein. The method 500 can be performed as operations performed at operation 308 described herein above with reference to FIG. 3.
The method 500 will be described with reference to FIG. 5 and further reference to FIGS. 1 and 2. The method 500 begins and proceeds to operation 502, where the connected car device 102 determines the mobility state 130 of the connected car device 102. From operation 502, the method 500 proceeds to operation 504, where the connected car device 102 determines the active UE category 124 based upon the mobility state 130. For example, if the connected car device 102 is in idle mode or has transitioned from a connected mode to an idle mode and is stationary, select or dynamically transition to a lower UE category, such as category 1 or category 0 or category M or any other lower category as defined in 3GPP standards, based upon device type, identity, and supported categories as well as applications. From operation 504, the method 500 proceeds to operation 506, where the connected car device 102 sends the active UE category 124 determined at operation 504 to the eNB 108. From operation 506, the method 500 proceeds to operation 508, where the connected car device 102 communicates with the eNB 108 in accordance with the active UE category 124.
From operation 508, the method 500 proceeds to operation 510, where connected car device 102 determines whether there has been a change to the mobility state 130. If the connected car device 102 determines that there has been a change to the mobility state 130, the method 500 returns to operation 502. If the connected car device 102 determines that there has not been a change to the mobility state 130, the method 500 proceeds to operation 512, where the connected car device 102 determines whether it is still operating in connected mode. If the connected car device 102 is still operating in connected mode, the method 500 returns to operation 508. If, however the connected car device 102 is not still operating in connected mode, the method 500 proceeds to operation 514, where the method 500 ends.
Turning now to FIG. 6, a flow diagram illustrating aspects of a method 600 for operating an eNB will be described, according to an illustrative embodiment of the concepts and technologies disclosed herein. The method 600 begins and proceeds to operation 602, where the eNB 108 receives the UE capability information element 138 from the connected car device 102. From operation 602, the method 600 proceeds to operation 604, where the eNB 108 receives the active UE category 124 in the UE capability information element 138 from the connected car device 102. From operation 604, the method proceeds to operation 606, where the eNB 108 communicates with the connected car device 102 in accordance with the active UE category 124 received at operation 604. From operation 606, the method 600 proceeds to operation 608, where the method 600 ends.
