[0002] At present, the public network has basically completed the construction of 4GLTE network, while the private network, which is still in the process of analog to digital transformation, is gradually connected with the public network and developing towards the direction of private network broadband in the face of broadband multimedia service needs such as high-definition images and videos. Due to the rigid requirements of private network industry users for voice reliability and security, the process of private network broadbandization is still a long way to go. In the face of this situation, broadband and narrowband integration is a good compromise. Due to the integration of broadband and narrowband, it is not only compatible with the current narrowband private network single-mode machine and broadband public network single-mode machine, but also can realize the mutual conversion between broadband and narrowband, and integrate well with the existing public and private networks, reducing user costs, expanding the network range and greatly satisfying various user scenarios.

[0003] With the advent of broadband and narrowband convergence, the coexistence of the two networks will face the problem of network selectivity, especially when using services, which network to choose to receive the service is a test of the processing capabilities of multi-mode converged terminals. Generally, the network coverage of the public network is much larger than that of the private network, but in some scenarios, the public network cannot cover but the private network can, or the public network can cover but the private network cannot, or the signal in the overlapping area of ​​the public and private networks will be strong in one area and weak in the other; therefore, it is particularly important for the receiving terminal to select an ideal call network path.

[0043] In order to further understand the structure, features and other purposes of the present invention, the preferred embodiments are described in detail with reference to the accompanying drawings as follows. The embodiments described in the drawings are only used to illustrate the technical solutions of the present invention and are not intended to limit the present invention.

[0044] like Figure 1 As shown, a device for implementing enhanced priority calls in a broadband and narrowband multi-mode fusion system includes a public network module 2 and a private network module 3, and the public network module 2 and the private network module 3 communicate through a serial port.

[0045] The device is provided with a receiving and judging sending module 1, which is electrically and signal-connected to the public network module 2 and the private network module 3 respectively. The receiving and judging sending module 1 is used to receive a new voice service and judge whether the new voice service is a public network POC voice service or a private network voice service. When the receiving and judging sending module 1 judges that the new voice service is a public network POC voice service, the public network POC voice service is sent to the public network module 2; when the receiving and judging sending module 1 judges that the new voice service is a private network voice service, the private network voice service is sent to the private network module 3.

[0046] The public network module 2 includes a public network priority judgment module 21 and a voice service access module 22; the public network priority judgment module 21 is electrically and signally connected to the receiving and judging sending module 1, the voice service access module 22 and the private network module 3 respectively. The public network priority judgment module 21 is used to judge whether the call priority of the new public network POC voice service from the receiving and judging sending module 1 is the highest priority. When the public network priority judgment module 21 judges that the call priority of the new public network POC voice service is the highest priority, the new public network POC voice service is sent to the voice service access module 22 to access the new public network POC voice service; when the public network priority judgment module 21 judges that the call priority of the new public network POC voice service is a new public network POC voice service of other priorities, the new public network POC voice service is sent to the private network module 3.

[0047] The private network module 3 includes a first private network determination module 31 , a second private network determination module 32 , a first priority comparison module 33 , a second priority comparison module 34 , a first signal strength comparison module 35 and a second signal strength comparison module 36 .

[0048] The first private network judgment module 31 is electrically and signally connected to the receiving and judging sending module 1, the public network priority judgment module 21, the second private network judgment module 32 and the voice service access module 22 respectively. The first private network judgment module 31 is used to judge whether the terminal is currently processing a voice service when receiving a new private network voice service from the receiving and judging sending module 1 or a new public network POC voice service from the public network priority judgment module 21. When the first private network judgment module 31 judges that no voice service is currently being processed, it sends the new voice service to the voice service access module 22 to access the new voice service; when the first private network judgment module 31 judges that a voice service is currently being processed, it sends the new voice service to the second private network judgment module 32.

[0049] The second private network judgment module 32 is electrically and signal-connected to the first priority comparison module 33; the second private network judgment module 32 is used to judge whether the voice service currently being processed is a public network POC voice service and the call priority is the highest priority when receiving a new voice service from the first private network judgment module 31. When the second private network judgment module 32 judges that the voice service currently being processed is a public network POC voice service and the call priority is the highest priority, the voice service currently being processed is maintained and no new voice service is connected; otherwise, the new voice service is sent to the first priority comparison module 33.

[0050] The first priority comparison module 33 is electrically and signally connected to the voice service access module 22 and the second priority comparison module 34, respectively. The first priority comparison module 33 is used to determine whether the call priority of the new voice service is greater than the call priority of the voice service currently being processed. When the first priority comparison module 33 determines that the call priority of the new voice service is greater than the call priority of the voice service currently being processed, the new voice service is sent to the voice service access module 22 to stop the current voice service and access the new voice service; otherwise, the new voice service is sent to the second priority comparison module 34.

[0051] The second priority comparison module 34 is electrically and signally connected to the first signal strength comparison module 35. The second priority comparison module 34 is used to determine whether the call priority of the new voice service is less than the call priority of the voice service currently being processed. When the second priority comparison module 34 determines that the call priority of the new voice service is less than the call priority of the voice service currently being processed, the current voice service is maintained and the new voice service is not connected; otherwise, the new voice service is sent to the first signal strength comparison module 35.

[0052] The first signal strength comparison module 35 is electrically and signal-connected to the second signal strength comparison module 36. The first signal strength comparison module 35 is used to determine whether the signal strength of the voice service currently being processed is greater than the strong signal threshold value. When the first signal strength comparison module 35 determines that the signal strength of the voice service currently being processed is greater than the strong signal threshold value, the current voice service is maintained and no new voice service is connected; otherwise, the new voice service is sent to the second signal strength comparison module 36.

[0053] The second signal strength comparison module 36 is electrically connected and signal-connected to the voice service access module 22. The second signal strength comparison module 36 is used to determine whether the signal strength of the new voice service is greater than the sum of the signal strength of the voice service currently being processed and the signal offset value. When the second signal strength comparison module 36 determines that the signal strength of the new voice service is greater than the sum of the signal strength of the voice service currently being processed and the signal offset value, the new voice service is sent to the voice service access module 22 to stop the current voice service and access the new voice service, otherwise the new voice service will not be accessed.

[0054] like Figure 2 As shown, the device of the present invention is a broadband and narrowband multi-mode fusion terminal (i.e. Figure 2 The medium multi-mode terminal MS) can work in both the private network DMR / PDT mode and the public network POC mode.

[0055] like Figure 3 As shown, in the broadband and narrowband multi-mode fusion system, the device of the present invention is used as a receiving terminal (which can be Figure 3 The transmitting terminal generally has a multi-mode terminal working in the public network POC mode (such as MS3, MS4, or MS1, MS2). Figure 3 MS3, MS4 in the private network), multi-mode terminals working in DMR / PDT mode (such as Figure 3 MS1, MS2 in it), POC dispatch console or POC mode telephone.

[0056] Set the call priority option for each call service (POC / DMR / PDT) initiated by each terminal. Call priorities are divided into 4 levels: 1, 2, 3 and 4, of which 1 is the lowest priority and 4 is the highest priority. That is, the call priority of the public network POC voice service is divided into public network priority level 1, public network priority level 2, public network priority level 3 and public network priority level 4; the call priority of the private network voice service is divided into private network priority level 1, private network priority level 2, private network priority level 3 and private network priority level 4, so that different users can use different priorities, and calls with higher priorities are often more guaranteed than calls with lower priorities. In the voice service call, there is a fixed bit segment to identify the level of call priority to identify the size of the priority.

[0057] Considering the importance of background dispatching and the wider coverage of the POC network, the call priority of the POC dispatch desk and emergency calls is set to the highest level 4, the call priority of telephones and senior leaders is set to level 3, the call priority of middle and low-level leaders is set to level 2, and the call priority of regular users is set to the lowest level 1. By dividing the priorities of different user groups, the call needs of users with different permissions can be better adapted, and the coordination of the entire communication network business is more reasonable to meet the needs of users at different levels.

[0058] Considering that the public network covers a larger area, in order to meet the needs of large-scale emergency communications, the highest priority level 4 of the public network POC voice service is set to be higher than the highest priority level 4 of the private network voice service, and other priorities are arranged in order of size, that is, public network priority level 4>private network priority level 4>public private network priority level 3>public private network priority level 2>public private network priority level 1, public network priority level 3 is the same as private network priority level 3, public network priority level 2 is the same as private network priority level 2, and public network priority level 1 is the same as private network priority level 1. That is, when a public network POC voice service with a priority level of 4 is received, no matter what level of priority the public private network voice service currently being processed is, the current service will be stopped and the new 4-level public network POC voice service will be connected; as for other priorities, generally high priority stops low priority, and priorities of the same level can be selected according to signal strength. Therefore, a strong signal threshold value and a signal offset value are also set to match the priority to select the best network path. The strong signal threshold and signal offset can be configured according to actual needs. The strong signal threshold of the device is preferably configured as -90dBm, and the signal offset is preferably configured as 6db. By setting the strong signal threshold and signal offset, the quality of the communication network under different environments can be more reasonably debugged according to the actual environment on site.

[0059] like Figure 4 As shown, the present invention also proposes a method for implementing enhanced priority calls in a broadband and narrowband multi-mode fusion system, which is implemented using the above-mentioned device to enable the broadband and narrowband multi-mode fusion terminal to select the best call network path as a receiving terminal. The specific implementation process is as follows.

[0060] When the receiving and judging sending module 1 of the device (i.e., the broadband and narrowband multi-mode fusion terminal) receives a new voice service, it first determines whether the new voice service is a public network POC voice service or a private network voice service ( Figure 4 If the new voice service is a public network POC voice service, the public network priority determination module 21 of the public network module 2 continues to determine whether the call priority of the new public network POC voice service is the highest priority ( Figure 4If it is the highest priority, the voice service access module 22 stops the current voice service and accesses the new public network POC voice service; otherwise, the subsequent processing flow of the new public network POC voice service is the same as the process of receiving the new private network voice service.

[0061] When the receiving and judging sending module 1 of the device (i.e., the broadband and narrowband multi-mode fusion terminal) receives a new private network voice service, the first private network judging module 31 of the private network module 3 judges whether the terminal is currently processing the voice service ( Figure 4 If the terminal is not currently processing a voice service, the voice service access module 22 immediately accesses a new voice service; otherwise, the second private network judgment module 32 judges whether the voice service currently being processed is a public network POC voice service and the call priority is the highest priority ( Figure 4 If yes, the currently processed voice service is maintained and no new voice service is connected; otherwise, the first priority comparison module 33 further determines whether the call priority of the new voice service is greater than the call priority of the currently processed voice service ( Figure 4 If yes, the current voice service is stopped and the new voice service is connected; otherwise, the second priority comparison module 34 further determines whether the call priority of the new voice service is lower than the call priority of the voice service currently being processed ( Figure 4 If the call priority of the new voice service is lower than the call priority of the currently processed voice service, the current voice service is maintained and the new voice service is not connected. When the call priority of the new voice service is equal to the call priority of the currently processed voice service, the first signal strength comparison module 35 determines whether the signal strength of the currently processed voice service is greater than the strong signal threshold value ( Figure 4 If yes, the current voice service is maintained and no new voice service is connected. That is, if the signal strength is greater than the strong signal threshold, it means that the quality of the signal is relatively good and there is no need to continue to judge, thereby improving the efficiency of finding a better communication link. Otherwise, the second signal strength comparison module 36 further determines whether the signal strength of the new voice service is greater than the sum of the signal strength of the voice service currently being processed and the signal offset value ( Figure 4 In step S8), the signal strength is compared with the sum of the signal offset value to determine whether the new voice service signal is much better than the current signal. The offset value is to ensure a certain signal gradient to avoid switching between two similar signals. If yes, the current voice service is stopped and the new voice service is entered. Otherwise, the new voice service will not be connected.

[0062] The device (i.e., broadband and narrowband multi-mode fusion terminal) and the priority calling method thereof of the present invention first determine whether the new voice service is a public network POC voice service or a private network voice service by setting a receiving and judging sending module, send the public network POC voice service to the public network module, send the private network voice service to the private network module, and then determine the call priority of the public network POC voice service through the public network priority determination module, determine the call priority of the new voice service and the currently processed voice service through the first private network determination module, the second private network determination module, the first priority comparison module and the second priority comparison module, realize the high priority to stop the low priority call network path selection, and determine the signal strength of the two voice services by the first signal strength comparison module and the second signal strength comparison module using the strong signal threshold value and the signal offset value, realize the call network path selection of the same level of priority, ensure that the broadband and narrowband multi-mode fusion terminal always maintains the best call network path for communication, and meets the specific user needs with broadband and narrowband networks. Finding an optimal call path according to the changes in the on-site environment through the above method can greatly improve the quality of communication.
