Description

SYSTEM AND METHOD FOR EDGE SERVICE ACCESS VIA UE HANDOVER

[0001] The present invention relates to a system and method for handing over a connection of an at least one user equipment (UE) from a first radio access (RA) to an at least one second radio access (RA) to access an at least one specialized service, using a system which can provide at least the functionality of the following modules including, but not limited to: user equipment (UE), first radio access (RA), and second radio access (RA).

[0002] In today's ever-evolving digital landscape, there's an increasing demand for providing extremely high data throughput, low latency, and high edge intelligence, just to maintain swift and seamless access to a specialized service. To meet these demands, 5G and 6G networks, new computational paradigms, and architectures are being explored. One promising solution revolves around facilitating smooth transitions for user equipment (UE) connections from one radio access network (RAN) to another, all while leveraging an optimization technology, such as mobile edge computing (MEC) or network slicing, enabling to access high-intelligence and high throughput service with usable latency. Moreover, the adoption of 5G / 6G systems provides the required bandwidth and network slicing capabilities to support a wide array of specialized services tailored to specific user needs. A solution that has these capabilities can significantly enhance the ease-of-use and quality of service (QoS) of the users' experience, which are key factors in the economic viability of deployed consumer-oriented services, such as, location specific services (e.g. Vehicle-to-everything, AR navigation), video streaming services, interaction with local IoT devices (e.g. multi-device experience, SmartThings), and many more.

[0003] US20230026671A1 (US' 671) presents a system called edge application handover client (EAHC), which is placed in a user equipment (UE) that uses application client (AC) information, such as type service, provider, location, context, and sendee requirements, to assist seamless edge application handovers of application clients between edge application servers (EAS). The system can only access the same service as the previous one, and the main purpose of the handover is just for continuity and seamless mobility transfer. In addition, it uses mainly edge application handover client (EAHC) instead of a radio access (RA).

[0004] US11190989B2 (US' 989) presents a system that provides a device having a processing circuit that is configured to transfer a handover request message to initiate the handover of a user equipment (UE) from a source Next Generation Node B (gNB) to a target gNB. This includes the reception of handover request acknowledgement, transfer of UE context modification request and response message, and the transfer of downlink data delivery status. The system only discusses the transmission of signals broadly defined as "data, control and / or other" and does not specifically disclose a trigger signal to request access to a specialized service.

[0005] US10390275B2 (US' 275) presents a handover method, an apparatus, and a system involving a mobile edge computing (MEC) entity. The handover method includes receiving, by a first base station, MEC information from a MEC entity, performing, by the first base station, a handover decision based on the MEC information, and transmitting, by the first base station, a handover request to a second base station in response to the handover decision. The system only discusses the handover method itself, which lacks the trigger aspect from the UE based on requested service.

[0006] The existing solutions in providing accessibility to these edge applications as well as suitable mobility have several limitations, such as handover decisions being primarily based on network KPI and mobility, service access handovers not covering handover decisions on the basis of specialized edge computing services, and accessed services usually using UE to UE connection via some radio device (e.g. P2P) instead of a connection of UE to an MEC server behind some radio device.

[0007] The above information is presented as background information only to assist with an understanding of the disclosure. No determination has been made, and no assertion is made, as to whether any of the above might be applicable as prior art with regard to the disclosure.

[0008] The present invention relates to a system for handing over a connection of an at least one UE from a first RA to an at least one second RA to access an at least one specialized service. The system comprises the at least one UE, the first RA, and the at least one second RA.

[0009] The at least one UE serves as the endpoint device that connects to the data network, facilitates communication, and accesses services and applications.

[0010] The first RA is capable of establishing connections with UE, communicating between different RAs and the Core Network, and managing the UE handover process for seamless transition of connection between RAs. The functions of the first RA include, but are not limited to, establishing connection to one of the at least one UE the at least one second RA, and the at least one data network, managing the connection of the at least one UE to an at least one data network, transmitting the at least one information to one of the at least one UE, the at least one second RA, and the at least one data network, wherein the at least one information comprises control information necessary for the handover procedure and information on the presence of the at least one specialized service of the at least one discoverable second RA, receiving the at least one information, such as the at least one trigger signal from the at least one UE, the information on the presence of the at least one specialized service in the at least one discoverable second RA, and the information from the data network, processing the at least one information, such as the at least one trigger signal from the at least one UE, the information on the presence of the at least one specialized service in the at least one discoverable second RA, and the information from the data network, and facilitating the handover of the connection of the at least one UE from the first RA where the at least one UE is initially connected to, to the at least one second RA requested.

[0011] The at least one second RA is utilized to deliver and administer the at least one specialized service requested by the at least one UE, ensuring quality of service (QoS) and accessibility for optimal user experience. The functions of the at least one second RA include, but are not limited to, establishing connection to one of the at least one UE, the first RA, and the at least one data network, receiving the at least one information from one of the at least one UE, the first RA, and the at least one data network, wherein the at least one information comprises the control information necessary for the handover procedure and the at least one trigger signal to request access to the at least one specialized service, transmitting the at least one information to one of the first RA, the at least one UE, and the at least one data network, wherein the at least one information comprises the at least one specialized service provided by the at least one second RA, managing the connection of the at least one UE to the at least one data network, and providing access to the at least one specialized service requested by the at least one UE.

[0043] The present invention relates a system for handing over a connection of an at least one UE from a first RA to an at least one second RA to access an at least one specialized service.

[0044] FIG.1aand FIG.1bpresents the diagram of the system for handing over a connection of an at least one UE from a first RA to an at least one second RA to access an at least one specialized service. The system100comprises an at least one UE102, a first RA104, and an at least one second RA106.

[0045] In an embodiment, the at least one UE102comes in the form of, but not limited to, mobile devices, controllers, and / or equipment. The at least one UE102is a device that can interface and generate traffic between itself and a data network110. The at least one UE102represents a device equipped with the necessary hardware and / or software capabilities to establish and maintain connections to data network110. It is conceivable that the at least one UE102refers to any device which can communicate to a data network110via wireless means to access services. The service includes, but is not limited to, communicating with another device within the same data network110. The at least one UE102communicates with the network infrastructure using a PDU session, enabling the exchange of data packets with the network. This connection is crucial for the seamless transmission of information, allowing users to stay connected, access online content, and engage in digital activities on the go. The at least one UE's102ability to initiate and manage PDU sessions ensures efficient data transfer, making it an indispensable tool for modern communication and connectivity.

[0046] The trigger that initiates the handover process comes in the form of, but not limited to, broadcasted token, manual input, or user prompts. The trigger from a user or UE-initiated input includes, but is not limited to, user input in the form of data comprising audio, text, sensor sources, UE-determined quantifiers, such as application-specific services and KPI exceptions to policy, and UE-determined indicators derived from user-input, such as app suggestions and user-specified preferences. Furthermore, the handover procedure can be initialized through the following processes, including but not limited to, from trigger via broadcast discovery query or forwarding of trigger query from current RA104to other prospective target RA106.

[0047] The first RA104and the at least one second RA106come in the form of any device that serves as an access point to a data network110. The RA104,106facilitates the connection between the at least one UE102and data networks110. The RA104,106is a network element equipped with hardware and software capabilities such as, but not limited to, establish, manage, and maintain wireless or wired connections with UEs102. Managing includes, but is not limited to, establishing connection, discarding connection, and handing over connection. These connections enable UEs102to access services and resources available within the data network110environment, and communicate with other devices, both locally and remotely. The RA104,106supports various wireless communication protocols and technologies, allowing UEs102to transmit and receive data packets seamlessly. The RA's104,106functionality includes the establishment and management of packet data unit (PDU) sessions with UEs102. These sessions facilitate the exchange of data packets between UEs102and the network infrastructure, enabling efficient data transfer and communication. The RA104,106ensures the reliability, security, and quality of service for these data transmissions, enhancing the overall user experience.　 The RA104,106may be part of a larger network topology that includes wired and / or wireless networks, such as, but not limited to, packet-switched networks, cellular networks (e.g., 6G, 5G), local area networks (LANs), wide area networks (WANs), and cloud computing networks.

[0048] The RA104,106is configured to hand over the UE 102 to one or more specialized services, rather than just the same service.

[0049] The RAs104,106are integrated with an optimization technology, such as, but not limited to, a mobile edge computing (MEC) or a network slicing, to reduce latency, improving performance, and enhancing the overall user experience.

[0050] The at least one specialized service that the at least one second RA offers is any consumer-oriented service, such as, but not limited to, location-specific services (e.g. Vehicle-to-everything, augmented reality navigation), video streaming services, interaction with local IoT devices (e.g. multi-device experience, SmartThings), and many more. The way to access the at least one specialized service includes, but is not limited to, using a single-network slice selection assistance information (S-NSSAI). A Network Slice includes, but is not limited to, type of use case service, network characteristics, and / or resources needed such as radio access network resources required by slice.

[0051] The at least one data network110includes one or more wired and / or wireless networks. For example, the network may include a packet switched network, a cellular network (e.g., a sixth generation (6G) network, a fifth generation (5G) network, a fourth generation (4G) network, such as a long-term evolution (LTE) network, a third generation (3G) network, a code division multiple access (CDMA) network, a public land mobile network (PLMN), a local area network (LAN), a wide area network (WAN), a metropolitan area network (MAN), a telephone network (e.g., the Public Switched Telephone Network (PSTN)), a private network, an ad hoc network, an intranet, the Internet, a fiber optic-based network, a cloud computing network, or the like, and / or a combination of these or other types of networks. In an embodiment, the at least one data network110is a system wherein several devices communicate with each other, such as, but is not limited to, the general internet, a private network, and a public cloud service.

[0052] In an embodiment, the handover procedure comes in the form of, but not limited to, XN handover or N2 handover. XN handover uses the XN interface to facilitate handover by direct communication between source and target gNB. The gNB is a specific type of RA104,106that uses 5G wireless networks. The gNB is responsible for providing wireless access to 5G-enabled devices and facilitating communication between these devices and the core network. The gNB implements the RA104,106functionality for 5G networks, supporting features such as beamforming, massive MIMO (Multiple Input Multiple Output), and higher data rates compared to previous generations of wireless technology. The XN interface is the interface between two gNBs. The N2 handover uses N2 interface to execute handover using AMF as facilitator between source and target gNB. N2 interface is the interface between the gNBs and the AMF / Core Network. The N2 handover can be done if XN handover is not possible (no direct communication between source and target gNB).

[0053] According to an embodiment, a system for handing over a user connection to another radio access (RA) which can provide access to one or more of these specialized services after a certain trigger may be provided. The trigger can be defined in such a way that approximates plausible services a user may want to access. By providing a seamless and frictionless mechanism for users to connect to locale-specific or specialized services / computing at the edge, the present invention improves quality of service (QoS) and accessibility to such applications.

[0054] According to an embodiment, to minimize user experience disruption, the UE connection can be transferred from one radio access (RA) to another radio access (RA) in response to a trigger.

[0055] FIG.2presents a flow chart for the method of handing over a connection of an at least one user equipment (UE) from a first radio access (RA) to an at least one second radio access (RA) to access an at least one specialized service. The method comprises the steps of:

[0056] Step200: establishing the connection between the first RA and the at least one second RA;

[0057] Step201: establishing the connection between the first RA and the at least one UE;

[0058] Step202: establishing the connection of the at least one UE to an at least one data network via the first RA;

[0059] Step203: transmitting an at least one information (e.g., first information), such as an at least one trigger signal to request access to the at least one specialized service, to the first RA via the at least one UE;

[0060] Step204: receiving the at least one information, such as the at least one trigger signal from the at least one UE, or the at least one specialized service provided by the at least one second RA, via the first RA;

[0061] Step205: transmitting the at least one information (e.g., second information) to the at least one UE, wherein the at least one information comprises the information on the presence of the at least one requested specialized service of the at least one discoverable second RA, via the first RA;

[0062] Step206: selecting the at least one second RA based on the at least one trigger signal from the at least one UE and the at least one specialized service that the at least one second RA provides;

[0063] Step207: processing the at least one information from the first RA via the at least one UE;

[0064] Step208: transmitting control information necessary for the handover procedure to the at least one second RA via the first RA;

[0065] Step209: executing the handover of the connection of the at least one UE to the at least one second RA via the first RA;

[0066] Step210: establishing the connection between the at least one UE and the at least one second RA;

[0067] Step211: establishing the connection of the at least one UE to the at least one data network via the at least one second RA; and

[0068] Step212: providing access to the at least one requested specialized service for the at least one UE via the at least one second RA.

[0069] FIG.3exhibits the paths of an XN and an N2 interfaces used by an XN handover procedure and an N2 handover procedure, respectively.

[0070] The handover procedure comes in the form of, but not limited to, XN handover or N2 handover. XNhandover procedure uses the XNinterface308to facilitate handover by direct communication between a source gNB300and a target gNB302. The gNB300,302is a specific type of RA that uses 5G wireless networks. The gNB300,302is responsible for providing wireless access to 5G-enabled devices and facilitating communication between these devices and the core network. The gNB300,302implements the RA functionality for 5G networks, supporting features such as beamforming, massive MIMO (Multiple Input Multiple Output), and higher data rates compared to previous generations of wireless technology. The XN interface308is the interface between two gNBs300,302. The N2 handover procedure uses the N2 interface310to execute handover using access and mobility management function (AMF)306as facilitator between the source300and the target gNB302. The N2 interface310is the interface between the gNBs300,302and the AMF / Core Network306. The N2 handover can be done if XN handover is not possible (no direct communication between the source gNB300and the target gNB302).

[0071] The AMF306is one of the control plane network functions (NF). The AMF306is located at the 5G Core Network (CN). The AMF306can be deployed as its own software module in the 5G CN. The AMF306manages the UE's102mobility, access, and connection to the core network. The UEs102and RAN communicate with AMF306to coordinate handover.

[0072] The Core Network is the network that can be interfaced to manage PDU sessions. The operations that govern PDU sessions include, but are not limited to, PDU session establishment, PDU session modification, and PDU session release.

[0073] The Service X304that the target gNB302offers may be any consumer-oriented service, such as, but not limited to, location-specific services (e.g. Vehicle-to-everything, augmented reality navigation), video streaming services, interaction with local IoT devices (e.g. multi-device experience, SmartThings). The way to access the at least one specialized service includes, but is not limited to, using a single-network slice selection assistance information (S-NSSAI). A Network Slice includes, but is not limited to, type of use case service, network characteristics, and / or resources needed such as radio access network resources required by slice.

[0074] FIG.4exhibits a possible sequence to handover a connection of an at least one UE from a source gNB to a target gNB using an XN handover procedure or an N2 handover procedure.

[0075] In step401, the data connection of the UE102is established to a user plane function (UPF)400via the source gNB300.

[0076] In step402, the handover is triggered by a user's attempt to access an Edge Service X304via the UE102.

[0077] In step403, a Service X request is sent from the UE102to the access and mobility management function (AMF)306in a form of a non-access stratum (NAS) message, for an allocated slice for the Service X304. The NAS message is the communication protocol between the UE102and the AMF306. The NAS is done through the connected gNB300as a forwarder.

[0078] In step404, the AMF306responds with a target S-NSSAI with its associated Service X304.

[0079] In step405, the UE's102response is used to modify the UE context via the UE Service Request to include a slice information.

[0080] In step406, the AMF306sends PDU session modification requests to the source gNB300, indicating the change in the NSSAI. If the source gNB300sees this change, it triggers a handover to the target gNB302that supports the service304corresponding to the allocated slice.

[0081] In step407, the handover of the connection of the UE102from the source gNB300to the target gNB302is executed using either the XN handover procedure or the N2 handover procedure.

[0082] In step408, the UE's102data connection is established to the UPF400via the target gNB302with the Service X304requested by the UE102.

[0083] In step409, the UE102accesses the Service X304at the edge via the target gNB302.

[0084] The UPF400is a 5G Core Network Function that facilitates the transfer of network traffic between the UE102and the Data Network (e.g. internet)110. The UPF400can be located at the Core Network or closer to the edge in an access network near the UE102. The UPF400can be deployed as a software module.

[0085] FIG.5exhibits a possible sequence to handover a connection of an at least one UE from a source gNB to a target gNB using an N2 handover procedure.

[0086] In step500, the source gNB300and the target gNB302send an NG setup request each to an AMF306to initiate setup for interaction with the AMF306. The gNBs300,302that support services are included in a custom S-NSSAI in their setup request. The AMF306, upon receiving this, notes discovery of a Service X304and the gNB that supports it, in this case, the target gNB302.

[0087] In step501, the data connection between the UE102and a UPF400is established via the source gNB300. The UE102accesses a data network110via the UPF400.

[0088] In step502, the handover is triggered by a user's attempt to access an Edge Service X304via the UE102. The UE102sends a NAS message to the AMF306via the source gNB300, requesting the details of the Service X304. The AMF306responds in a form of the NAS message with a custom S-NSSAI associated with the Service X304.

[0089] In step503, the UE102keeps a copy of the NSSAI from the source gNB300. If the custom S-NSSAI is not included, then the UE102sends a Service Request message requiring a specific NSSAI including the custom S-NSSAI for the Service X304.

[0090] In step504, once the Service Request is complete, the source gNB300detects unsupported custom S-NSSAI in a UE session. The UE102triggers the handover to the target gNB302. Any handover can be supported, but in this sequence, the N2 handover procedure is used.

[0091] In step505, after the handover is complete, the data connection is still connected to the same UPF400, but the Service X304is now available at the edge.

[0092] FIG.6exhibits a more expanded explanation of the possible sequence to handover a connection of an at least one UE from a source gNB to a target gNB using an N2 handover procedure.

[0093] In step600, the source gNB300and the target gNB302send an NG setup request each to an AMF306to initiate setup for interaction with the AMF306. The gNBs302that support services are also included in a custom S-NSSAI in their setup request. The AMF306, upon receiving this, will note discovery of a Service X304and the gNB that supports it, in this case, the target gNB302. The AMF306notes the Service capabilities of the connected gNBs300,302beforehand, through starting configuration of a non-3GPP-compliant communication.

[0094] In step601, a data connection between the UE102and a UPF400is established via the source gNB300. The UE102accesses a data network110via the UPF400.

[0095] In step602, the handover is triggered by a user's attempt to access an Edge Service X304via the UE102. The UE102sends a NAS message to the AMF400via the source gNB300, requesting the details of the Service X304. The AMF400responds in a form of the NAS message with the global IDs of the connected gNBs302that support the Service X304.

[0096] In step603, the UE102determines if the connected gNB, which is the source gNB300, supports the Service X304. If not, the UE102sends a MeasurementReport message to the connected gNB300, with a custom message attached that requests for the handover which includes the list of candidate gNB global IDs. The custom message can be inserted in a non-critical extension of the message or other parameters that are not used by the source gNB300.

[0097] In step604, if a custom handover request is detected from the MeasurementReport, the source gNB300selects the target gNB302from the included candidate gNB list. The source gNB300triggers the handover to the target gNB302. Any handover is supported, but in this sequence, the N2 handover procedure is used.

[0098] In step605, after the handover is complete, the data connection is still connected to the same UPF400, but the Service X304is now available at the edge and is accessible to the UE102.

[0099] FIG.7a,7b, and7cpresent the use cases for an embodiment according to the invention wherein the invention is utilized to handover a UE connection to smaller radio devices on a basis of intent to localized services available in their respective edge servers or localized RA capabilities like an increased bandwidth or a capacity to handle massive / critical lot use cases.

[0100] FIG.7apresents the UE102which transmits a service-based trigger to initiate a handover of the connection of the UE102from an RA 1104to an RA 2106to access an immersive navigation service, which is a specialized service area 2700provided by the RA 2106.

[0101] The specialized service area700refers to a specific region within a network that is configured to provide tailored services or optimized performance for particular applications or user groups, such as the UE102.

[0102] The immersive server702is a specialized server or a network infrastructure optimized to deliver content, data, or services for immersive experiences, such as, but not limited to, augmented reality (AR) technology, extended reality (XR) technology, streaming immersive media content, or supporting real-time interactions within virtual environments.

[0103] FIG.7band7cpresent the handover of the connection of the UE102, which now starts from the RA 2106, to an RA 3706, which is also connected to an immersive server 3710, that enables the RA 3706to provide the immersive navigation service, which is a specialized service area 3708. Accessing the immersive navigation service must be connected to the RA that provides the same immersive service as in the immersive server 2702. Instead of being handed over to an RA 4712, the handover goes to the RA 3706, since it can provide the same immersive service for an augmented reality (AR) navigation.

[0104] In thisembodiment, it has advantages of providing different services based on localized service, or specialized service area700,708, providing different services based on fidelity, or preferences, and being able to have localized analytics based on service usage, engagement, and interest.

[0105] According to an embodiment, a seamless and frictionless mechanism for users to connect to locale-specific or specialized services / computing at the edge and increase in quality of experience (e.g. lower latency) for access to specific services and content may be provided. Moreover, with the use of radio access (RA), the present invention also provides significant advantages such as broader coverage, efficient resource allocation, seamless handover capabilities, scalability, and adherence to standardized protocols. These advantages contribute to the robustness and effectiveness of RANs in delivering high-quality mobile services and applications.

[0106] FIG.8shows an embodiment according to the invention wherein the RAs utilize content delivery nodes (CDN) for handing over a UE's connection to access contents such as, but not limited to, visual media, information from other RAs, or combinations thereof.

[0107] When storing a content806,808,810in various RAs104,106,706through their CDNs800,802,804, this allows for content management and more secure data. The content806,808,810is cached for various RAs104,106,706based on location, preferences, and priority. Caching the content806,808,810stored in CDNs800,802,804allows for faster load times, reduced bandwidth costs, and improved availability and redundancy. The UE102may request the content806,808,810across the CDNs800,802,804, such as, but not limited to, localized visual media, audio streams from radio / podcasts, news alerts based on the local area, or combinations thereof. In addition, the embodiment also allows for the allocation of various settings and preferences for the content806,808,810, such as type of content, media quality, and / or media availability. Utilizing CDNs800,802,804enables the distribution of content volume, localized analytics based on content views, engagement, and interest, and the censoring and limiting of content to only authorized users.

[0108] The CDN's800,802,804functions encompass the storage, distribution, and optimization of web content. This involves caching frequently accessed content like web pages, images, and videos. The CDN800,802,804employs load balancing mechanisms across multiple servers to ensure optimal resource utilization and uphold high availability standards. Additionally, it integrates content optimization features such as image compression and file minification to improve delivery efficiency and decrease page load times. Furthermore, CDNs800,802,804prioritize security measures such as DDoS protection, SSL / TLS encryption, and web application firewalls to mitigate cyber threats effectively.

[0109] In this embodiment, it has advantages of distributing content volume, being able to have localized analytics based on content views, engagement, and interest, and being able to censor and limit content to only authorized users.

[0110] FIG.9shows an embodiment according to the invention wherein the invention is used to trigger via a UE, a handover of its connection from an unauthorized RA to an authorized RA to access a private access network (AN).

[0111] The third embodiment can be used as an additional procedure that operates by rerouting the connection of the UE900to the another radio access (RA)904which is connected to the private access network (AN)906. Utilizing the invention in this way allows the invention to provide a secure API to which wireless devices can connect to, enable devices to switch connection types from "personal mode" to "work mode" that can open up new resources or authorization to access certain services or connections that are only available on the private AN906, be an alternative to virtual private networks (VPN) for small containerized services that can operate on lower layers for less overhead. The authorized RA904provides the UE900with authorized connection to the private AN906. The private AN906provides the UE900access to restricted resources only available on that network.

[0112] In similarity with the first two embodiments as described in FIG.7a,7b,7c, and8, the UE900initiates the handover of the connection of the UE900from one RA902to another RA904by transmitting a request to access a specialized service, which includes, but not limited to, specialized service area700,708, content806,808,810, a private AN906, or combinations thereof. The trigger that initiates the handover process comes in the form of, but not limited to, broadcasted token, manual input, or user prompts. The trigger from a user or UE-initiated input, which includes, but is not limited to, user input in the form of data, which can be, but not limited to, audio, text, sensor sources, UE-determined quantifiers, including, but not limited to, application-specific services, and / or KPI exceptions to policy, UE-determined indicators derived from user-input, including, but not limited to, app suggestions, and user-specified preferences. Furthermore, the handover procedure can be initialized through the following processes, including but not limited to, from trigger via broadcast discovery query or forwarding of trigger query from current RA to other prospective target RA. In this embodiment, instead of requesting access to the specialized service area700,708or the content806,808,810, the UE900requests access to the private AN906via transferring its connection from the unauthorized RA902to the authorized RA904. After handing over the UE's900connection to the authorized RA904, the UE900connection to the internet remains established, but now with an additional access to the private AN906. To put it briefly, this embodiment's advantages are having a more secure access point, enhanced security, and privacy, and being capable of operating on lower layers for less overhead.

[0114] Referring to FIG. 1, the electronic device 1001 (e.g., user equipment 102) in the network environment 1000 may communicate with an electronic device 1002 via a first network 1098 (e.g., a short-range wireless communication network), or communicate with at least one of an electronic device 1004 and a server 1008 via a second network 1099 (e.g., a long-range wireless communication network).

[0138] As used in connection with various embodiments of the disclosure, the term "module" may include a unit implemented in hardware, software, or firmware, and may interchangeably be used with other terms, for example, "logic," "logic block," "part," or "circuitry". A module may be a single integral component, or a minimum unit or part thereof, adapted to perform one or more functions. For example, according to an embodiment, the module may be implemented in a form of an application-specific integrated circuit (ASIC).

[0139] Various embodiments as set forth herein may be implemented as software (e.g., the program 1040) including one or more instructions that are stored in a storage medium (e.g., the internal memory 1036 or the external memory 1038) that is readable by a machine (e.g., the electronic device 1001). For example, a processor (e.g., the processor 1020) of the machine (e.g., the electronic device 1001) may invoke at least one of the one or more instructions stored in the storage medium and execute it. This allows the machine to be operated to perform at least one function according to the at least one instruction invoked.
