An electronic device of a single radio environment can provide LTE service using circuit switched fall back (CSFB) that determines whether paging information of a circuit switched (CS) service network is received over an LTE network. When receiving a paging signal of the CS service network over the LTE network, the electronic device connects (or accesses) the CS service network (e.g., a 2nd generation (2G)/3rd generation (3G) network) and provides a voice call service. For example, the 2G network can include one or more of a GSM network and a code division multiple access (CDMA) network. The 3G network can include one or more of a wideband-CDMA (WCDMA) network, a time division-synchronous CDMA (TD-SCDMA) network, and an evolution-data optimized (EV-DO) network.
Alternatively, the electronic device of the single radio environment can provide LTE service using single radio LTE (SRLTE), which determines whether the paging information is received by periodically switching every radio resource (e.g., receive antennas) to the CS service network (e.g., the 2G/3G network). Upon receiving the paging signal of the CS service network, the electronic device provides the voice call service by connecting the CS service network (e.g., the 2G/3G network).
Alternatively, the electronic device of the single radio environment can provide LTE service using single radio dual system (SRDS), which determines whether the paging information is received by periodically switching some of radio resources (e.g., receive antennas) to the CS service network (e.g., the 2G/3G network). Upon receiving the paging signal of the CS service network, the electronic device provides the voice call service by connecting the CS service network (e.g., the 2G/3G network).
FIG. 1 illustrates a network environment including an electronic device according to an embodiment of the present disclosure. Referring to FIG. 1, an electronic device 101 includes a bus 110, a processor 120, a memory 130, an input/output interface 150, a display 160, and a communication interface 170. Alternatively, the electronic device 100 can omit at least one of the components and/or include an additional component.
The bus 110 includes a circuit for connecting the components (e.g., the processor 120, the memory 130, the input/output interface 150, the display 160, and the communication interface 170) and delivering communications (e.g., a control message) therebetween.
The processor 120 includes one or more of a CPU, an AP, and a communication processor (CP). The processor 120 processes an operation or data for control of and/or communication with another component of the electronic device 101.
The processor 120, which may be connected to the LTE network, determines whether a call is connected over the CS service network using caller identification information (e.g., a caller phone number) of the CS service network (e.g., the 2G/3G network). For example, the processor 120 may receive incoming call information (e.g., a CS notification message or a paging request message) of the CS service network over the LTE network (e.g., CSFB). For example, the processor 120 being connected to the LTE network may receive incoming call information (e.g., a paging request message) over the CS service network (e.g., SRLTE).
When receiving the incoming call information (e.g., a CS notification message or a paging request message) of the CS service network over the LTE network, the processor 120 may obtain caller identification information from the incoming call information. The processor 120 displays the caller identification information on its display 160. The processor 120 may determine whether to connect the call based on input information corresponding to the caller identification information displayed on the display 160. For example, when detecting input information corresponding to an incoming call rejection, through the input/output interface 150, the processor 120 may restrict the voice call connection and maintains the LTE network connection. For example, when detecting input information corresponding to an incoming call acceptance, through the input/output interface 150, the processor 120 connects the voice call by connecting to the CS service network.
When receiving the incoming call information (e.g., a CS notification message or a paging request message) of the CS service network over the LTE network, the processor 120 may obtain caller identification information from the incoming call information. The processor 120 may determine whether to connect the call by comparing the caller identification information with a reception control list. For example, when the caller identification information is included in a first reception control list (e.g., a blacklist), the processor 120 may restrict the voice call connection and maintains the connection to the LTE network. For example, when the caller identification information is not included in the first reception control list (e.g., the blacklist), the processor 120 may connect the voice call by connecting to the CS service network. For example, when the caller identification information is included in a second reception control list (e.g., a white list), the processor 120 connects the voice call by connecting to the CS service network.
When receiving the incoming call information (e.g., a paging request message) of the CS service network over the LTE network, the processor 120 may transmit an incoming call response message (e.g., a paging response message) to the CS service network. The processor 120 may suspend the LTE service and receives the caller identification information (e.g., a CS call (CC) setup message) from the CS service network. The processor 120 may determine whether to connect the call by comparing the caller identification information with the reception control list. For example, when the caller identification information is included in the first reception control list (e.g., the blacklist), the processor 120 may restrict the voice call connection and resumes the LTE network connection. For example, when the caller identification information is not included in the first reception control list (e.g., the blacklist), the processor 120 may connect the voice call by connecting to the CS service network. For example, when the caller identification information is included in the second reception control list (e.g., the white list), the processor 120 connects the voice call by connecting to the CS service network.
The memory 130 may include volatile and/or nonvolatile memory. The memory 130 may store commands or data (e.g., the reception control list) relating to at least another component of the electronic device 101. The memory 130 stores software and/or a program 140. The program 140 includes a kernel 141, middleware 143, an application programming interface (API) 145, and applications 147. At least some of the kernel 141, the middleware 143, and the API 145 may be referred to as an operating system (OS).
The kernel 141 may control or manage system resources (e.g., the bus 110, the processor 120, or the memory 130) used for performing an operation or function implemented by the other programs (e.g., the middleware 143, the API 145, or the applications 147). Further, the kernel 141 provides an interface through which the middleware 143, the API 145, or the applications 147 may connect the individual elements of the electronic device 101 to control or manage the system resources.
The middleware 143 may function as an intermediary for the API 145 or the applications 147 to communicate with the kernel 141 and exchange data. In addition, the middleware 143 may process one or more task requests received from the applications 147 according to priorities thereof. For example, the middleware 143 may assign priorities for using the system resources (e.g., the bus 110, the processor 120, the memory 130, and the like) of the electronic device 101, to at least one of the applications 147. For example, the middleware 143 may perform scheduling or load balancing on the one or more task requests by processing the one or more task requests according to the priorities assigned thereto.
The API 145 is an interface through which the applications 147 control functions provided from the kernel 141 or the middleware 143, and may include at least one interface or function (e.g., an instruction) for file control, window control, image processing, text control, etc.
The input/output interface 150 transfers instructions or data input from a user or another external device to the other element(s) of the electronic device 101. Further, the input/output interface 150 outputs the instructions or data received from the other element(s) of the electronic device 101 to the user, a first external electronic device 102, a second external electronic device 104, or a server 106.
The display 160 may include a liquid crystal display (LCD), a light emitting diode (LED) display, an organic LED (OLED) display, a micro electro mechanical system (MEMS) display, an electronic paper display, etc. The display 160 displays various types of content (e.g., a text, images, videos, icons, symbols, webpages, etc.) for the user. The display 160 may include a touch screen that receives a touch input, a gesture input, a proximity input, a hovering input, etc., from an electronic pen or the user's body part.
The communication interface 170 establishes communication between the electronic device 101 and the first external electronic device 102, the second external electronic device 104, or the server 106. For example, the communication interface 170 can communicate with the first external electronic device 102 through a wireless communication or a wired communication 164, and communicate with the second external electronic device 104 or the server 106 in connection to a network 162 through wireless communication or wired communication. For example, the wireless communication may conform to a cellular communication protocol including at least one of LTE, LTE-advanced (LTE-A), CDMA, Wideband CDMA (WCDMA), universal mobile telecommunications system (UMTS), wireless broadband (WiBro), and GSM.
The wired communication 164 can include at least one of universal serial bus (USB), high definition multimedia interface (HDMI), recommended standard 232 (RS-232), and plain old telephone service (POTS).
The network 162 may include a telecommunications networks, a computer network (e.g., a local area network (LAN) or a wide area network (WAN)), the Internet, a telephone network, etc.
The electronic device 101 provides the LTE service in the single radio environment by use of at least one module functionally or physically separated from the processor 120.
Various embodiments of the present disclosure will be described with reference to a display that includes a bent or curved area and is applied to a housing of an electronic device 101, in which a non-metal member and a metal member (e.g., a metal bezel) are formed through dual injection molding, but are not limited thereto. For example, the display 160 may be applied to a housing, in which a metal member or a non-metal member is formed of a single material.
Each of the first external electronic device 102 and the second external electronic device 104 may be a same or a different type of device as the electronic device 101.
The server 106 may include a group of one or more servers.
All or some of the operations to be executed by the electronic device 101 may be executed by the first external electronic device 102, the second external electronic device 104, and/or the server 106. For example, when the electronic device 101 should perform a certain function, the electronic device 101 may request some functions that are associated therewith from the first external electronic device 102, the second external electronic device 104, and/or the server 106, instead of or in addition to executing the function or service by itself. The first external electronic device 102, the second external electronic device 104, or the server 106 may execute the requested functions or additional functions, and may transmit the results to the electronic device 101. The electronic device 101 may provide the requested functions or services by processing the received results as they are or after additionally.
