## Background
TECHNICAL FIELD
The present disclosure relates to a telephony collaboration system and method. More particularly, the present disclosure relates to a telephony collaboration system and method for a trusted environment.
BACKGROUND
Due to the popularity of cellphones in recent years, individuals often use their cellular telephone or cellphone as their primary communication device even when the individual or user is at home or at work. However, when the cellphone rings or vibrates due to an incoming call, it may be located anywhere, such as the user's home or work. Therefore, if the user is not close enough to the cellphone, the user may miss the incoming call because the user cannot hear the ring of the cellphone or cannot reach the cellphone in time. For example, when the user is at home and needs to make an urgent call, if the cellphone is not close by, then the user cannot quickly make the call. Similarly, if the user hears the call in a room in which the user is located, but the cellphone is located in another room, then the user is likely to miss the call because the user cannot reach or locate the cellphone in time and will miss the call. Also, if the cellphone is located in a briefcase or purse and the cellphone rings, then the user may not have enough time to retrieve the cellphone from the briefcase or purse and answer the call. As a result, the user will miss the call.
Accordingly, there is a need for a telephony collaboration system and method which allows collaboration of phones in a particular environment.
The above information is presented as background information only to assist with an understanding of the present 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 present disclosure.

The communication unit 138 may support a short range protocol and may communicate using an SRW network (e.g., WiFi, BT, NFC, etc.), network communications (e.g., Internet, a LAN, a WAN, a telecommunication network, the cellular network 142, a satellite network, etc.), and/or a POTS.
FIG. 2 is a flowchart illustrating a process of providing a TCM service according to an embodiment of the present disclosure.
The TCM service may include a process performed by an admin device (e.g., a TCM host) and/or a guest device (e.g., a TCM guest). The admin device may be a device which creates a TCM group and which can be the only device authorized to remove the group. The guest device may be a device which subscribes to an existing group and which may be automatically assigned as the guest device.
Referring to FIG. 2, a flowchart 200 is illustrated, in which the flowchart 200 illustrates a process of providing a TCM service. In this process, upon starting the TCM service, in operation 201 an electronic device initially determines whether the wireless function of the electronic device is enabled. For example, the electronic device may be the admin device, such as the master device 110 as illustrated in FIG. 1 and may also be the guest device, such as the guest device 130 as illustrated in FIG. 1. If the wireless function of the admin device is not enabled, the operation of providing the TCM service is terminated.
If the wireless function of the admin device is enabled, the process continues to operation 203. At operation 203, the admin device determines whether to create a new group, to subscribe the guest device to a new/existing group or to join the guest device to an already subscribed to group.
If at operation 203 it is determined to create a new group, at operation 205, the admin device creates a new group and assigns the new group a name. Then, at operation 207 a login scheme is created in order to, for example, identify whether the user is authorized to access the TCM service. Thereafter, at operation 209, a registry of the admin device is updated, so as to be able to accurately track registrations of various TCM devices. Finally, at operation 211, the admin device enters a listening mode to listen for the guest device to join the newly created group.
The admin device also enters a standby mode at operation 227. When a new TCM request is received while the admin device is in the standby mode at operation 227, the admin device establishes a new data connection at operation 229 and the admin device sends/receives data at operation 231. After operation 231 the admin device returns to standby mode in operation 227.
Meanwhile, if at operation 203 it is determined that an electronic device, such as the guest device is to subscribe to a new/existing group, at operation 213 the guest device scans for available groups using, for example an SRW device scanner. Once a group has been found the guest device sends a request to an admin device of the found group for a new subscription to the found group at operation 215. Thereafter, at operation 217, the admin device determines whether to accept the request. If the request is not accepted, the process returns to operation 203, and if the request is accepted the process continues to operation 219. At operation 219, a login scheme is created between the admin device, the guest device and any other devices subscribed and/or joined to the group.
Alternatively, if at operation 203 it is determined that the guest device has already joined a subscribed group the guest device scans for available groups to which the guest device has subscribed at operation 221. Once a group is found at operation 221, the guest device attempts to become registered in the group and a determination as to whether the registration is successful is performed at operation 223.
If the registration is not successful, then the process returns to operation 221 or operation 223. Further, if the registration is successful, then the registry and a log of the admin device are updated at operation 225. It is noted that the updating of the registry and the log at operation 225 follows the registration of the guest device to an already subscribed to group as indicated at operation 223 or follows the creating of the login scheme when the guest device subscribes to the new/existing group as indicated at operation 219.
Thereafter, at operation 227 the electronic device (e.g., the admin device and/or the guest device) enters a standby mode. When a new TCM request is received while the electronic device is in the standby mode at operation 227, the electronic device establishes a new data connection at operation 229 and the electronic device sends/receives data at operation 231. After operation 231 the electronic device returns to standby mode in operation 227.
The TCM service includes subscribing to and/or unsubscribing from the service. The subscribing and/or unsubscribing to/from the service is required only once. The process allows enabling/disabling of TCM features including the creation and/or removal of device identification, TCM authentication, group IDs and the like.
The registration of the guest device to an already created group includes automatically searching and registering any nearby TCM devices. The process also includes maintaining the status of all online devices and unregistering a device that moves out of the range of the TCM group.
Finally, the TCM authentication includes a user creating a TCM authentication scheme during the subscription of the TCM service.
FIG. 3 is a block diagram illustrating an MO collaborative system according to an embodiment of the present disclosure.
Referring to FIG. 3, an MO collaborative system 300 is illustrated, where the MO collaborative system 300 includes a TCM master device 310, a relay device 320, a TCM client device 330 and a base station 340.
A detailed description of the elements of each of the devices, as illustrated in FIG. 3 and of the base station 340 has already been provided with respect to FIG. 1 and therefore a detailed description of these elements is not provided herein. For example, the TCM master device 310 corresponds to the TCM master device 110, as illustrated in FIG. 1, the TCM client device 330 corresponds to the TCM client device 130, as illustrated in FIG. 1, and the relay device 320 corresponds to the relay device 120, as illustrated in FIG. 1.
As illustrated in FIG. 3, when an incoming call is received at the TCM master device 310 of the MO collaborative system 300, the TCM master device 310 broadcasts control signals 350 to all nearby TCM devices, such as for example the TCM client device 330. Thereafter, all registered devices perform a notification action, such as playing a TCM ringtone, and/or displaying a visual notification. However, it is to be noted that the notification action is not limited thereto and many other forms of notifying the user of the master device 310 may be performed. A user of the TCM client device 330 is then able to answer the incoming call upon passing an authentication.
The authentication (e.g., a TCM authentication) is performed by the TCM master device 310 and/or the TCM client device 330 and may be the same as the authentication performed by the TCM master device 110 and/or the TCM client device 130. The user may pass the TCM authentication in order to unlock and answer the incoming call in any of the devices registered in the TCM subscription system. Further, it is noted that the call history may be updated only in the master device 310.
FIG. 4 is a block diagram illustrating an MT collaborative system according to an embodiment of the present disclosure.
Referring to FIG. 4, an MT collaborative system 400 is illustrated, where the MT collaborative system 400 includes a TCM master device 410, a relay device 420, a TCM client device 430 and a base station 440.
A detailed description of the elements of each of the devices, as illustrated in FIG. 4 and of the base station 440 has already been provided with respect to FIG. 1 and therefore a detailed description of these elements is not provided herein. For example, the TCM master device 410 corresponds to the TCM master device 110, as illustrated in FIG. 1, the TCM client device 430 corresponds to the TCM client device 130, as illustrated in FIG. 1, and the relay device 420 corresponds to the relay device 120, as illustrated in FIG. 1.
As illustrated in FIG. 4, when the user wishes to place a call, the user may pick up any of the devices (e.g., the TCM client device 430) registered in the TCM subscription system and place the call using the connection between the base station 440 and the TCM master device 410. In order for the TCM client device 430 to place the call, signals 450 are transmitted to the TCM master device 410 from the TCM client device 430. Furthermore, in order for the TCM client device 430 to place the call, an unlock authentication is required and only TCM functions may be accessible in the TCM client device 430 upon passing the unlock authentication. It is also noted that although the call history is updated, the update may occur only in the TCM master device 410.
FIG. 5 is an illustration of a TCM subscription system including various groups according to an embodiment of the present disclosure.
Referring to FIG. 5, a TCM subscription system 500 is illustrated, where the TCM subscription system 500 includes two groups, Group 1 and Group 2. Each group may include an admin device and several guest devices. For example, Group 1 includes three devices, p1-1, p1-2 and p1-3, one of which is the admin device and the remaining devices being guest devices. Similarly, Group 2 may also include various devices, p2-1, p2-2, p2-3 and p2-4, one of which is the admin device and the remaining devices being guest devices. Each of the device of Group 1 may communicate with each other using an SRW network (e.g., WiFi, BT, NFC, etc.) and each of the devices of Group 2 may communicate with each other using an SRW network (e.g., WiFi, BT, NFC, etc.).
It is noted that one device may belong to more than one group. For example, as illustrated in FIG. 5, device p1-1 may belong to Groups 1 and 2. Telephony functionality sharing is based on the TCM groups. As such, device p1-1 can subscribe to multiple groups and therefore, it may share the resources from either Group 1 or Group 2. Additionally, for example, device p1-1 can communicate to the devices of Group 1 and Group 2 using an SRW network (e.g., WiFi, BT, NFC, etc.).
The TCM subscription system according to an embodiment of the present disclosure promotes sharing existing resources of cellphones without adding new hardware costs to the system. In addition, the TCM subscription system connects cellphones together into one or multiple groups, which can be either cloud based or locally managed. Further, the TCM subscription system aims at collaborating not only just simple voice call functions but messaging and other cellphone functions. Finally, the technology behind telephony collaboration is much more dynamic and advanced.
In the TCM subscription system according to an embodiment of the present disclosure, an admin device is a TCM device that has created a TCM group and can add or remove other TCM devices from the TCM group. Each TCM group may only have one admin device. A guest device is another TCM device that has joined the TCM group. There may be many guest devices that have joined the TCM group. A new guest device sends a subscription requests to the admin device and becomes a member after approval.
In the TCM subscription system according to an embodiment of the present disclosure, after TCM groups are formed, TCM collaboration may be performed. When referring to TCM collaboration, a master device is a device that is, for example, owned by a user but is out of reach and is the device that handles incoming or outgoing cellular calls. Further, when referring to TCM collaboration, a client device is a device that is picked by the user to receive an incoming call or make an outgoing call using the SRW connection to the master device. An admin device may be a master device and client device and a guest device may also be a master device and a client device.
While the present disclosure has been shown and described with reference to various embodiments thereof, it will be understood by those skilled in the art that various changes in form and details may be made therein without departing from the spirit and scope of the present disclosure as defined by the appended claims and their equivalents.
