Detailed Description
In the following description, for purposes of explanation and not limitation, specific details are set forth, such as particular system structures, techniques, etc. in order to provide a thorough understanding of the embodiments of the invention. It will be apparent, however, to one skilled in the art that the present invention may be practiced in other embodiments that depart from these specific details. In other instances, detailed descriptions of well-known systems, devices, circuits, and methods are omitted so as not to obscure the description of the present invention with unnecessary detail.
Before describing the embodiments of the present invention, first, a "first device" and a "second device" appearing in the following embodiments are defined, it is assumed that a called device of an incoming call is the "first device", and a target device of the incoming call for call forwarding is the "second device", where "the first and second" are merely convenient for representation and reference herein, so as to distinguish the called device from the target device of call forwarding, and do not mean that there is necessarily a first device and a second device corresponding thereto in a specific implementation manner of the present invention. In addition, in the embodiment of the present invention, the device includes, but is not limited to, a mobile phone, a fixed phone, a smart watch, and other devices having a voice call capability and a short-range communication capability, and the short-range communication is used to implement a communication process between the first device and the second device, and includes, but is not limited to, a short-range communication mode such as bluetooth and WiFi.
Fig. 1 shows an implementation flow of a call forwarding method for an incoming call provided by an embodiment of the present invention, which is detailed as follows:
in S101, a first device acquires service information of second devices providing a call forwarding service through near field communication, and authorizes call forwarding services of N of the second devices according to the acquired service information, where N is an integer greater than 0.
S101 authorizes a call forwarding service of a second device by a first device, and for the link, an interaction process between the second device and the first device is as shown in fig. 2:
1. the first device enables the call forwarding service, broadcasts out, and searches for a second device in its vicinity that can provide the call forwarding service.
2. The second device enables the call forwarding service, and broadcasts service information of the call forwarding service thereof to the outside.
The service information of the call forwarding service includes, but is not limited to, a device name of the second device, a Media Access Control (MAC) address, and other information, so that the first device can know the relevant situation of the second device according to the service information provided by the second device.
3. The first device selects one or more second devices from the one or more second devices searched by the first device according to the service information provided by the second devices.
4. The first device sends a call forwarding service request to the selected second device.
5. The second device accepts the call forwarding service request of the first device and locally stores the service information of the first device in the second device.
Obviously, in this step, the second device may also reject the call forwarding service request of the first device, and the first device cannot forward its incoming call to the second device.
6. The second device returns a request acceptance response to the first device.
7. The first device marks the second device as registered in its local service list.
Thus, the first device completes authorization of the call forwarding service of the second device, and the second device has the right to answer the incoming call of the first device.
After the first device completes authorization of the call forwarding service of the second device, the first device may also maintain a local service list of the first device, periodically detect the operating states of N authorized second devices, and locally update the operating states of N authorized second devices according to the detection result, so as to ensure that when an incoming call needs to be forwarded, the incoming call can be successfully forwarded to the authorized second devices. For this link, the interaction process between the second device and the first device is as shown in fig. 3:
1. the first device periodically sends a status query request to the second device that is in a registered state in its service list.
For example, the first device periodically sends a heartbeat packet to the second device to detect whether the second device is online or powered on and is in a state of being able to receive an incoming call.
2. And the second equipment returns a status report to the first equipment according to the status inquiry request.
3. And the first equipment updates the service list according to the status report returning condition of the second equipment.
For example, if the first device does not receive the status report returned by the second device, the registered status of the second device is revoked in the service list if the second device is considered to be out of the near field communication range of the first device.
In S102, the first device sets corresponding call forwarding types for the authorized N second devices.
The call forwarding types include: unconditional forwarding, busy line forwarding, forwarding without answer (i.e. normal ringing but not answering of the first device) or forwarding without access (e.g. the first device is powered off or not in a service area), and according to the difference of the operator network joined by the first device, the call forwarding types that can be set in S102 are also different, and only the call forwarding types supported by the operator can be set in S102.
In S103, the first device sets, in the joined operator network, the number of the second device corresponding to each call forwarding type as a call forwarding target corresponding to the call forwarding type, so that when there is an incoming call to the first device, the incoming call is forwarded to one of the authorized N second devices.
In the embodiment of the present invention, for a second device that processes a registered state in a service list local to a first device, in an operator network to which the first device joins, a number of the second device is set as a call forwarding target of a call forwarding type corresponding to the second device, so that an incoming call that is called to the first device can be forwarded to the second device through an existing service provided by the operator.
Specifically, the method comprises the following steps: when an incoming call is incoming to the first device, the operator network detects an incoming call response obtained in the first device by the incoming call of the incoming call, so that a call forwarding type corresponding to the incoming call is judged, and the incoming call is automatically forwarded to a second device corresponding to the call forwarding type. It should be noted that, when the call forwarding type is unconditional forwarding, when the operator network detects that an incoming call calls the first device, the operator network directly forwards the incoming call to the second device, and no call action is generated at the first device.
For example, within the short-distance communication range of the smart phone, if the call forwarding service of the fixed phone and the smart watch is authorized, the call forwarding type set for the smart watch is busy, and the call forwarding type set for the fixed phone is incoming call unreachable, when the call forwarding type obtained by the incoming call in the first device is busy, it indicates that the user is using the first device to talk at the moment, the incoming call is forwarded to the smart watch, so that the user can know the incoming call condition through the smart watch while talking; when the call transfer type of the incoming call obtained in the first equipment is that the incoming call is not reachable, the call transfer type indicates that the state of the call network of the first equipment is not good at the moment, and then the incoming call is transferred to the fixed telephone to ensure better call quality.
As an embodiment of the present invention, when there are multiple second devices corresponding to the same call forwarding type, the first device may further set priorities for the multiple second devices, as shown in fig. 4:
after S101, the method further includes:
s104, the first device sets priority for the N authorized second devices.
Accordingly, in the present embodiment, S103 is implemented by S105 in fig. 4:
and S105, the first device sets the number of the second device corresponding to each call forwarding type and having the highest priority as a call forwarding target corresponding to the call forwarding type.
In this embodiment, the priority may be sequentially set for the second device corresponding to each call forwarding type according to the user's desire, and the number of the second device with the highest priority is set in the operator network, so that when there is an incoming call and the call forwarding is required, the operator network automatically forwards the incoming call to the second device that the user desires to answer most. Meanwhile, if the first device finds that the second device with the highest priority corresponding to a certain call forwarding type is unavailable in the daily detection process, the number of the second device with the second highest priority can be set in the operator network, so that the call forwarding is ensured to be carried out smoothly.
Further, as an embodiment of the present invention, when the call forwarding type is busy, as shown in fig. 5, the method further includes:
s106, when an incoming call is incoming to the first equipment and the first equipment is busy, the first equipment transfers the corresponding second equipment through the short-distance communication notification busy line so that the second equipment triggers an incoming call prompt;
s107, receiving a transfer request initiated by the second device according to the incoming call prompt, and hanging up the incoming call according to the transfer request so as to transfer the incoming call to the second device.
For this link, the interaction process between the second device and the first device is as shown in fig. 6:
1. the first device receives the incoming call and the first device is busy, and the first device informs the second device of the incoming call information.
The second device is corresponding to busy line transfer.
2. The second device generates a prompt for arrival of the incoming call with call forwarding.
For example, a prompt message may pop up on a smartphone or be prompted by a light or ring on a landline telephone.
3. The second device initiates a transfer operation and sends a transfer request to the first device.
For example, when the smartphone detects a click command to the pop-up prompt message, or the fixed-line telephone detects that the receiver of the smartphone is picked up, a transfer operation is initiated, and a transfer request is sent to the first device.
4. The first device accepts the transfer request and hangs up the incoming call.
5. An incoming call is received in the second device, which is forwarded to the carrier.
The first device actively hangs up the incoming call, and thus, the operator detects that the call forwarding type is busy line forwarding, and forwards the incoming call to the second device.
In a specific implementation, on the side of the first device, that is, the called device, the following improvements may be made to support implementation of the present scheme:
1. the near field communication function and the user interface for discovering, authorizing and canceling the authorization of the call transfer service are added.
2. And adding a function of periodically detecting the state of the registered second equipment and dynamically adjusting the service list according to the detection result.
3. A short-range communication function of transmitting and receiving a transfer request is added.
4. And adding a call forwarding setting function, including a switch for starting a call forwarding service and an interface for quickly selecting nearby equipment as a target equipment for call forwarding.
On the side of the second device, the target device, the following improvements may be made to support implementation of the present solution:
1. and a near field communication function and a user interface for issuing, receiving and rejecting the authorization request by the call transfer service are added.
2. A near field communication function for receiving a transfer request and transmitting a transfer request is added.
3. For the intelligent device, a user interface capable of prompting the transfer incoming call is added, for the fixed-line telephone, an indicator lamp is added to prompt that the user has the transfer incoming call, and a key is added to actively request the call transfer.
Further, for a fixed telephone:
4. a WiFi or Bluetooth chip is added to a traditional fixed telephone, and a near field communication protocol is supported by programming.
Meanwhile, in a specific implementation process, when the adopted near field communication protocol is a bluetooth protocol, the bluetooth broadcast data frame is extended to support sending of the custom information, table 1 shows a frame structure of the bluetooth broadcast data frame, and table 2 shows a format of a PDU field in the bluetooth broadcast data frame:
TABLE 1
| Preamble | Access Address | PDU | CRC |
| 1 (byte) | 4 (byte) | 2-39 (bytes)) | 3 (byte) |
| 0x25 | 0x8E89BED6 |
TABLE 2
In the above frame structure, the AdvData part of the PDU payload (Playload) can carry a vendor-defined data structure, and thus can be used to transmit data such as the data shown in table 3:
TABLE 3
| Protocol prefix | Request/Response | Data |
| 6 (byte) fixed content | 2 (byte) | 0-23 (byte) |
Wherein:
the Protocol prefix field is used to identify the identity of the information specified by the present invention.
The Request/Response field is used to define the command type for sending requests and responses between devices.
The Data field is used to convey Data information corresponding to the Request/Response.
The WiFi Beacon protocol can be expanded in the same manner, and whether the distance between the devices is within the effective range or not is judged by calculating the distance between the devices according to the signal intensity transmitted in the expanded protocol.
The reference signal strength txPower, which is the signal strength that the receiving side should detect 1 meter from the transmitting device, can be conveyed through the "Data" field in table 3.
The distance is calculated by the reference signal strength txPower and the measured signal strength rsi, and the specific calculation parameters need to be adjusted according to the used transmission technology.
The call transfer scheme of the incoming call provided by the embodiment of the invention can judge the response situation of the incoming call and the answering expectation of the user so as to realize automatic call transfer of the incoming call and provide the communication efficiency of the user for communication through communication equipment such as a mobile phone and the like.
It should be understood that, the sequence numbers of the steps in the foregoing embodiments do not imply an execution sequence, and the execution sequence of each process should be determined by its function and inherent logic, and should not constitute any limitation to the implementation process of the embodiments of the present invention.
