TECHNICAL FIELD

Embodiments herein relate in general to displaying communication options for a user to communicate with other users, and more particularly relates to displaying presence information.

BACKGROUND ART

Communication devices, particularly mobile or portable electronic devices, have become increasingly prevalent for communication purposes. Many users use mobile electronic devices as their primary means of communication. Mobile electronic devices can perform various functions such as a phonebook function, a cellular phone service function, a Voice over Internet Protocol (“VoIP”) phone service function, functions associated with various software applications stored thereon, an email access function, functions associated with internet capabilities, calendar functions, a music playback function, a video playback function, and the like.

Users may use phonebook functionality to select a contact of another user with whom the users wish to communicate. The contact of a user generally includes the user's username, address, phone number, and e-mail addresse address. Further, the contacts may be sorted or organized. For example, the contacts may be sorted based on usernames, and a user may search the contacts by scrolling through usernames displayed in the contacts.

However, the other user of the selected contact may decline a communication request when communication is unavailable or not desired, for example, when driving or working in an office.

Referring now to the drawings, where similar reference characters denote corresponding features consistently throughout the figures, there are shown embodiments.

FIG. 1 is a block diagram of a system including electronic devices and a server according to an embodiment.

As illustrated in FIG. 1, the system 100 may include electronic devices 104A, 104B, 104C, . . . , and 104N, a server 102, and contacts database 106. The electronic device 104A may transmit information regarding a change in a device state of the electronic device 104A to the server 102. The device state of the electronic device 104 may be but not limited to a state of a battery or power source of the electronic device 104, and an operation mode of the electronic device 104. Further, the device state of the electronic device 104A may further pertain to user context information. The user context information may indicate a situation of the electronic device 104A or a user who is using the electronic device 104A. The change in the device state may be detected at the electronic device 104A and the information regarding the change in the device state may be transmitted to the server 102 from the electronic device 104A.

In some embodiments, communication availability of a user may be determined based on behavioral parameters. The behavioral parameters may be related to a device mode, an activity of the user, a location of the user, and an occasion. The activity of the user may be determined by sensors of the electronic device 104A to sense a certain movement of the electronic device 104A. For example, when the electronic device 104A senses a certain amount of vertical or horizontal movement, the activity of the user may be determined as workout. For example, when the electronic device 104A senses insignificant movement, the activity of the user may be determined as sleep. The occasion may be determined by a schedule entered by a user of the electronic device 104A.

How many communication requests from each contact are accepted and how many communication requests from each contact are rejected may be calculated for each behavioral parameter, specifically, for each subcategory of each behavioral parameter. For example, when the user accepts a relatively fewer calls while driving than while not driving, so declined call ratios (or accepted call ratios) during driving mode and non-driving mode may be determined.

A first weighted value Wi may be assigned to each behavioral parameter. W1, W2, W3, and W4 may be assigned to a device mode parameter, an activity parameter, a location parameter, and an occasion parameter, respectively, but are not limited thereto. More or less than 4 behavioral parameters may be used according to an embodiment. The first weighted value Wi may be fixed for each behavioral parameter, for example, W1, W2, W3, and W4 may be 50, 30, 15, and 5, but are not limited thereto. Generally, a device mode is set by a user, so its weight value W1 may be greater than other behavioral parameters W2, W3, and W4.

A second weighted value Wix may be further assigned to each behavioral parameter. The second weighted value Wix may be calculated based on a declined call ratio. For example, when a user has accepted 300 calls out of 1,000 calls during ultra power saving mode (UPSM), the user's second weighted value W13 may be equal to (1000-3000)/1000*100(%)=70%. The user's declined call ratio may be determined based on communication information regarding communications between the user and other users, and may be calculated based on data collected or trained over a certain time period. When the user's first and second weight values W1 and W13 are 50 and 70%, a device mode parameter C1 may be equal to W1><W13/100=35. The device mode parameter C1 may be used to determine a communication availability parameter Ci. The second weighted value Wix may be assigned to each subcategory of each behavioral parameter, and each behavioral parameter may be determined based on a multiply of the first and second weighted values Wi and Wix.

Referring to Table 1, a subcategory of the device mode parameter may include airplane mode, emergency mode, ultra power saving mode (UPSM), driving mode, and Do-Not-Disturb (DND) mode, but is not limited thereto. Referring to Table 1, a subcategory of the activity parameter may include sleep activity, workout activity, and non-workout activity, but is not limited thereto. Referring to Table 1, a subcategory of the location parameter may include home location, office location, and other location, but is not limited thereto. Referring to Table 1, a subcategory of the occasion parameter may include holiday occasion, festival occasion, and personal event occasion, but is not limited thereto.

A device mode parameter C1, an activity parameter C2, a location parameter C3, and an occasion parameter C4 may be determined based on a multiply of first and second weighted values Wx and Wix.

A communication availability parameter Ci may be determined as a sum of behavioral parameters C1, C2, C3 and C4. In general, each behavioral parameter Ci may be computed as Equation 1.

Ci=Σ(Wi×(ΣWix)/Si)/100 Equation 1

In Equation 1, i denotes an index corresponding to each category, x represents an index of subcategories in a category, Si represents a number of subcategories in ith category, Wi represents a weighted value of ith category and Wix represents a weighted value of xth subcategory in ith category. The communication availability parameter C may be determined as per Equation 2.

C=ΣCi Equation 2

The communication availability parameter C may be determined based on a sum of behavioral parameters Ci. Based on the communication availability parameter, communication availability may be determined using Equation 3.

LPS=100−C Equation 3

In Equation 3, LPS stands for live phonebook status, and indicate communication availability of a user. In some embodiments, the communication availability of the user of the electronic device 104A may be determined based on behavioral parameters and communication information regarding communications between the user of the electronic device 104A and users of electronic devices 104B, 104C to 104N. The communication information may be used to calculate the second weighted value. The users of the electronic devices 104B to 104N may be represented as contact identifiers displayed in a contact list of the user of the electronic device 104A, but are not limited thereto. Likewise, a contact identifier of the user of the electronic device 104A may be displayed in a contact list of the users of the electronic device 104B to 104N, but is not limited thereto. For example, a contact of the user of the electronic device 104A may be displayed in a contact list of a user of the electronic device 104B, and not displayed in a contact list of a user of the electronic device 104N, according to their relationship. Communication information of the user of the electronic device 104A may include information about a number of times a communication is accepted by the user of the electronic device 104A from the users of the electronic devices 104B to 104N, and a number of times a communication is rejected by the user of the electronic device 104A from the users of the electronic devices 104B to 104N.

In some embodiments, preferred modes of communication of each user may be prioritized based on presence information. The preferred mode of communication of each user may be displayed in a contact list. Presence of a user may indicate communication availability of the user, and the presence information may be referred to as information regarding communication availability. Preferred modes of communication of a user may be determined based on information regarding communication availability of the user.

In some embodiments, the server 102 may receive state information regarding a device state of the electronic device 104A from the electronic device 104A and determine priority information of the user of the electronic device 104A associated with users of the electronic devices 104B to 104N. The priority information of the user may be determined based on whether the other users of the electronic device 104B to 104N are included in a priority contact list of the user. The priority contact list of the user may be stored in a contact database 106. Further, communication information regarding communications between the electronic device 104A and each of the electronic devices 104B to 104N may be determined. The presence information of the user of the electronic device 104A for each of the users of the electronic devices 104B to 104N may be computed based on the priority information, the state information, and the communication information of the user.

In an embodiment, presence information of a user, that is, information regarding communication availability of the user, may be determined based on communication information regarding communications between the user and other users. The communication information may be determined based on a declined call ratio of the user. The presence information of the user may be adjusted according to a caller. For example, when the caller is included in a priority contact list of the user, communications between the caller and the user are more frequent as compared to other users, the caller's calls are accepted by the user in a higher ratio as compared to other users, or communication availability of the user to the caller may be greater than other users. The presence information (presence or communication availability) may be referred to as live phonebook status (LPS), and caller-specific presence information (presence or communication availability) may be referred to as live phonebook status final (LPSf).

For example, when a user of the electronic device 104B is in a priority contact list of the user of the electronic device 104A, and a declined call ratio is equal to ten percentage, the presence information of the user of the electronic device 104A, denoted as LPSf (Final Live Phonebook Status), may be computed using Equation 4, which may allow LPSf of the user of the electronic device 104A to vary according to who is making a call to the user of the electronic device 104A. The declined call ratio may be determined based on a history of communication between the users of the electronic device 104A and 104B, specifically, communications initiated by the user of the electronic device 104B.

LPSf=LPS−(10% of LPS) Equation 4

When the user of the electronic device 104B is not in the priority contact list of the user of the electronic device 104A, the declined call ratio may double. Accordingly, the presence information is computed using Equation 5.

LPSf=LPS−(2*10% of LPS) Equation 5

The value LPSf may be pushed to the electronic device 104B. The above method may be implemented for each of the users of the electronic devices 104B to 104N.

In some embodiments, each of the electronic devices 104A to 104N may detect a change in user context information based on behavioral parameters, such as but not limited to information about device modes of the electronic devices 104A to 104B, activities of the users of the electronic devices 104A to 104B, locations of the users, and occasions. The user context information may indicate a situation of an electronic device or a user who is using the electronic device. Each behavioral parameter may be determined based on a number of accepted communications and a number of declined or rejected communications between each of the electronic devices 104A to 104N.

The electronic devices 104A, 104B to 104N (hereinafter collectively referred to as an electronic device 104) may be any electronic device, such as desktop computers, portable computers, smart phones, tablet computers, wearable devices, and the like. The electronic device 104 may also include a display for displaying any data.

Embodiments are intended to include or otherwise cover any type of display, including known, related art, and/or later developed technologies.

The server 102 may include a non-transitory computer medium that may be configured to receive and transmit communication requests and/or communication responses to and from the electronic device 104. The server 102 may be any or a combination of a server, a local computer connected to the electronic devices 104.

The contacts database 106 may store lists of contacts associated with a user of the electronic device 104. The contacts database 106 may be, but not limited to, a relational database, a navigational database, a cloud database, an in-memory database, a distributed database and the like.
