Fig. 1 illustrates a schematic diagram of a transit apparatus 100 for narrowband and broadband communication according to an embodiment of the present invention. As shown in fig. 1, the intelligent relay station 100 includes a DMR module 112, a master module 114, and an LTE module 116. The DMR module 112 is connected to the main control module 114 through a local interface to perform a DMR relay function. Specifically, on the one hand, the DMR module 112 receives a DMR signal sent by a DMR terminal through the DMR antenna 110, and sends the DMR signal to the main control module 114; on the other hand, the DMR module 112 receives DMR signals conforming to the DMR protocol from the main control module 114, and transmits the DMR signals to the target DMR terminal through the DMR antenna 110. The LTE module 116 is also connected to the host module 114 through a local interface and is responsible for communication with the core network server. Similarly, in one aspect, the LTE module 116 receives external LTE signals through the LTE antenna 118 and transmits the LTE signals to the host module 114; on the other hand, the LTE module 116 receives an LTE signal conforming to the LTE protocol from the host module 114. The main control module 114 is responsible for access (such as login, call, data transfer, etc.) of DMR terminals, and intelligent conversion processing of voice, media, and data. Those skilled in the art will appreciate that the DMR module 112 in fig. 1 may be other narrowband modules, such as a PDT module, a Tetra module, etc., according to a smart transfer platform compatible narrowband protocol. Likewise, those skilled in the art will appreciate that the LTE module 116 in fig. 1 may be other broadband modules, such as a WiFi module, an ethernet module, etc., according to an intelligent relay platform compatible broadband protocol.
Fig. 2 illustrates a schematic diagram of a converged narrowband and wideband communication system 200, in accordance with one embodiment of the present invention. As shown in fig. 2, the converged communication system 200 includes two intelligent relay stations 212 and 213, a converged server 214, a converged dispatch station 216, a converged management station 218, apps 220 of two public network handsets, and two public network interphones 221. The two intelligent transfer platforms 212 and 213 and the convergence server 214 are based on broadband communication, the convergence dispatching platform 216, the convergence management platform 218 and the convergence server 214 are based on broadband communication, and the convergence server 214 is based on broadband communication with the App 220 of the public network mobile phone and the public network interphone 221 through a broadband base station. Optionally, intelligent relay stations 212 and 213 are connected to the public network via LTE, WiFi or ethernet. One of the two intelligent relay stations 212 is in narrowband-based communication with the plurality of DMR terminals 210 and the other intelligent relay station 213 is in narrowband-based communication with the plurality of PDT terminals 211. Preferably, the convergence server 213 and the convergence dispatcher 216 are located on a public network cloud platform, and a user can access the convergence dispatcher 216 through a client program on a local computer.
All devices and terminals of the converged communication system 200 have a system user code, which is a unique identity of the device or terminal in the converged communication system for terminal login, call, data interaction, etc. As shown in Table 1 below, the system user code comprises a high-to-low x-bit enterprise code, an n-bit identity code, and an m-n-bit sub-code, wherein the n-bit identity code and the m-n-bit sub-code form an m-bit identifier, and the m-bit identifier complies with the specification of the narrowband protocol employed by the intelligent transfer platform.
TABLE 1 systematic user coding
| x position | n position | m-n position |
| Enterprise coding | Identity coding | Sub-coding |
For example, in the embodiment of fig. 2, the intelligent relay station 212 in communication with the DMR terminal 210 employs a DMR protocol, and the intelligent relay station 213 in communication with the PDT terminal 211 employs a PDT protocol. Both the DMR protocol and the PDT protocol specify identifiers for mobile stations and peripheral devices that are 24 bits in length, so in the embodiment of fig. 2, m equals 24. Those skilled in the art will appreciate that m may take different values depending on the narrowband protocol.
Table 2 shows an embodiment of identity codes of devices and terminals in a converged communication system, wherein the length of the identity codes is 4 bits.
Table 2 one embodiment of identity encoding
| 0x0 | 0x1 | 0x2 | 0x3 | 0x4 | 0x5 | 0x6 | Others |
| DMR terminal | PDT terminal | Intelligent transfer platform | Public network interphone | Public network App | Dispatching desk | Management desk | Retention |
In the embodiment of table 2, when communicating within the narrowband private network, the DMR terminal 210, PDT terminal 211, and intelligent relays 212 and 213 all use 24-bit identifiers as communication IDs to identify them, with the first 4 bits as identity codes and the last 20 bits as sub-codes.
When the DMR terminal 210 or the PDT terminal 211 needs to access the convergence communication system 200 (for example, the DMR terminal 210 or the PDT terminal 211 needs to log in the convergence server 214, the DMR terminal 210 or the PDT terminal 211 needs to call a public network App 220 (such as an App installed on a public network mobile phone or a public network computer) or a public network interphone 221, or the DMR terminal 210 needs to communicate with the PDT terminal 211, or the like), the DMR terminal 210 or the PDT terminal 211 first communicates with the intelligent relay station. After receiving the signaling sent by the DMR terminal 210, the intelligent relay station 212 resolves an m-bit Identifier (ID) and a signaling of the DMR terminal. At the same time, the intelligent relay platform converts DMR signaling into broadband signaling for communication with the convergence server 214 through the LTE module of the intelligent relay platform 212.
The following describes a relay station, a narrowband terminal device, and a login method of a broadband terminal device according to an embodiment of the present invention with reference to fig. 3 to 5.
According to embodiments of the invention, after power up, the transfer platform needs to log into the convergence server 214 for communication. As shown in fig. 3, in step 302, the relay station sends login signaling to the convergence server 214 through its broadband module 116, the login signaling containing metadata indicating that the relay station requests login and account and key information associated with the relay station. After receiving the login signaling, the convergence server 214 parses the login signaling, and detects that the login signaling contains metadata indicating that the relay station requests to login, step 304. In an embodiment of the present invention, the relay station may be registered with the convergence server through specific software, including setting an account number and a key of the relay station, and the convergence server adds the corresponding account number and key in pairs to a list of registered relay stations. In step 306, the convergence server 214 verifies whether the relay station is a registered relay station according to the account number and the key of the relay station in the received login signaling. In some embodiments, the login signaling directly contains the account number and key of the transfer table; in other embodiments, the login signaling contains the device serial number of the transfer station or the card number of the SIM card installed thereon, and one device serial number or the card number of one SIM card corresponds to one specific account number and key, so that whether the transfer station is a registered transfer station can be verified only by the device serial number or the card number of the SIM card.
When the relay station is a registered relay station, the fusion server 214 replies a login result of successful login, step 307; after receiving the login result that the login is successful, the relay station establishes a connection with the convergence server 214, and sends a heartbeat signal to the convergence server 214 through the broadband module 116 at a predetermined time interval, step 310. If the fusion server 214 does not receive a heartbeat signal from the relay station for more than a specified time interval, the connection between the fusion server 214 and the relay station is disconnected. When the relay station is not a registered relay station, the convergence server 214 replies with a login failure code, step 308, that the relay station has not established a connection with the convergence server 214.
Similar to the transfer of the login convergence server 214, the process of the broadband terminal device 220 or 221 to login to the convergence server is shown in fig. 5. In step 502, the broadband terminal device 220 or 221 sends login signaling to the convergence server 214, where the login signaling includes metadata indicating that the broadband terminal requests to login and account and key information associated with the broadband terminal device 220 or 221. After receiving the login signaling, the convergence server 214 parses the login signaling, and detects that the login signaling contains metadata indicating that the broadband terminal requests to login, step 504. In the embodiment of the invention, the broadband terminal device can be registered with the convergence server through specific software, including setting an account and a key of the broadband terminal device, and the convergence server adds the corresponding account and key in pair to a list of the registered broadband terminal devices. In step 506, the convergence server 214 verifies whether the broadband terminal device 220 or 221 is a registered broadband terminal device according to the account and the key of the broadband terminal device 220 or 221 in the received login signaling. In some embodiments, the login signaling directly contains the account and key of the broadband terminal device; in other embodiments, the login signaling contains the device serial number (such as IMSI number, IMEI number) of the broadband terminal device or the card number of the SIM card installed thereon, and one device serial number or the card number of one SIM card corresponds to one specific account number and key, so that it can be verified whether the broadband terminal device is a registered broadband terminal device only by the device serial number or the card number of the SIM card.
When the broadband terminal device 220 or 221 is a registered broadband terminal device, the convergence server 214 replies a login result of successful login, step 507; after the broadband terminal device 220 or 221 receives the login result indicating that the login is successful, the broadband terminal device 220 or 221 establishes a connection with the convergence server 214, and the broadband terminal device 220 or 221 transmits a heartbeat signal to the convergence server 214 at a predetermined time interval, step 510. If the convergence server 214 does not receive the heartbeat signal from the broadband terminal device 220 or 221 for more than a prescribed time interval, the connection between the convergence server 214 and the broadband terminal device 220 or 221 is disconnected. When the broadband terminal device 220 or 221 is not the registered broadband terminal device, the convergence server 214 replies the code of the login failure, step 508, and the broadband terminal device 220 or 221 does not establish a connection with the convergence server 214.
The narrowband terminal logs in the convergence server slightly differs from the relay station and the broadband terminal, and fig. 4 illustrates a flow 400 of logging in the convergence server by the narrowband terminal by taking a DMR terminal as an example. As shown in fig. 4, in step 402, the DMR terminal sends a login signaling to the relay station using a short message. Here, the short message uses a specific prefix (e.g., 0 xaabcc) as an identifier of the login signaling, so that login signaling compliant with the DMR protocol can be obtained. The relay station receives and parses the login signaling through its narrowband module to obtain the m-bit identifier of the DMR terminal and the prefix of the signaling (i.e., the signaling header), step 404. Through the prefix of the signaling, the relay station may determine whether the received signaling is a login signaling that the DMR terminal requests to log in, step 406. When the prefix of the signaling indicates that the received signaling is the login signaling for the DMR terminal to request to log in, the controller of the relay platform converts the received signaling into a broadband login signaling, where the broadband login signaling includes metadata indicating that the DMR terminal requests to log in and a system user code of the DMR terminal (including an m-bit identifier of the DMR terminal and an x-bit enterprise code of the relay platform), in step 407. When the prefix of the signaling indicates that the received signaling is not the login signaling requested by the DMR terminal to log in, the relay station does not convert the signaling into the broadband login signaling, step 408. In some embodiments, the intelligent relay determines the signaling type according to the signaling header of the received narrowband signal. When the parsed signaling is signaling related only to the DMR protocol, the intelligent relay directly responds to the signaling without converting the signaling into broadband signaling. When the parsed signaling is signaling that requires communication with the broadband side, e.g., login signaling, logged device signaling, voice-related signaling (such as a robbery request, voice content, etc.), etc., the intelligent relay platform converts DMR signaling to broadband signaling for transmission.
After step 407, the relay station sends broadband login signaling to the convergence server through its broadband module, step 410. In the embodiment of the invention, the narrowband terminal equipment can be registered with the fusion server through specific software, the system user code of the narrowband terminal equipment is set, and the fusion server adds the corresponding system user code to the list of the registered narrowband terminal equipment. After receiving the broadband login signaling, the convergence server compares the system user code of the DMR terminal with the list of the registered narrowband terminal devices to verify whether the DMR terminal is a registered narrowband terminal device, step 412. When the DMR terminal is a registered narrowband terminal device, the convergence server replies a successful DMR terminal login result to the relay station, step 413; if the DMR terminal is not a registered narrowband terminal device, the convergence server replies a login failure code to the relay station, step 414. After receiving the successful login result of the DMR terminal, the relay station converts the successful login result of the DMR terminal into a narrow-band signal, where the narrow-band signal includes a signaling header for identifying that the DMR terminal has logged in and an m-bit identifier of the DMR terminal, step 416; subsequently, the relay station sends a narrowband signal that the DMR terminal successfully logs in through its narrowband module, step 418.
The transit platform and the broadband terminal may need to request the latest address book from the convergence server after successful login for subsequent processing, such as establishing a call group. Fig. 6a illustrates a flow diagram 600 for updating an address book of a relay in accordance with one embodiment of the present invention. After the relay station successfully logs in, the relay station may send an update address book request signaling to the convergence server, step 602. In response to the address book update request signaling, the convergence server retrieves the group information of all narrowband terminals registered through the relay station from the contact list, step 604. Then, in step 606, the convergence server replies to the relay group information. In some embodiments, in response to a group assignment request relating to a certain transfer table, the convergence server stores group information for the transfer table in a contact list of the convergence server; in response to a group allocation request related to a certain narrowband terminal device, the convergence server stores the group information of the narrowband terminal device in a contact list of the convergence server.
Similarly, fig. 6b illustrates a flowchart 610 of updating an address book of a broadband terminal according to an embodiment of the present invention. After the broadband terminal successfully logs in, the broadband terminal may send an address book update request signaling to the convergence server, step 612. In response to the address book update request signaling, the convergence server retrieves the group information with the broadband terminal in the contact list, step 614. Then, in step 616, the convergence server replies to the broadband terminal with the group information. In some embodiments, in response to a group assignment request associated with a broadband terminal, the convergence server stores group information for the broadband terminal in a contact list of the convergence server.
The narrowband terminal communicates with the broadband terminal, the convergence server and the like through the relay station, but the relay station has a limitation on a signal coverage range, and the narrowband terminal cannot communicate with the broadband side through the relay station beyond the signal coverage range of the relay station. Fig. 7 illustrates a flow diagram 700 for roaming of a narrowband terminal according to an embodiment of the invention. And writing a roaming frequency point list into the DMR terminal through the configuration programming software, step 702. It should be understood that the frequency point order in the roaming frequency point list can be set as required. After receiving the successful login result of the DMR terminal login from the convergence server, the relay station will send a synchronization signaling to the DMR terminal at regular time, step 704. After receiving the synchronization signaling, the DMR terminal analyzes the signal strength (RSSI) of the synchronization signaling from the synchronization signaling, step 706; subsequently, the DMR terminal determines whether the signal strength is less than a set threshold, step 708. If the signal strength is not less than the set threshold, the DMR terminal still locks the frequency point of the relay station, i.e., maintains communication with the relay station, step 709; otherwise, the DMR terminal will sequentially detect the signal strength of the synchronization signaling of each roaming frequency point according to the roaming frequency point list, step 710. Then, the DMR terminal determines whether the signal strength of the synchronization signaling of each roaming frequency point is smaller than a set threshold, step 712. If the signal strength of the detected synchronization signal of the roaming frequency point is smaller than the set threshold, the DMR terminal will detect the signal strength of the synchronization signal of the next roaming frequency point, step 713. If the signal strength of the detected synchronization signal of the roaming frequency point is not less than the set threshold, the DMR terminal will lock to the new relay station corresponding to the roaming frequency point, step 714. The DMR terminal then sends a registration short message to the new relay station, step 716, to register the new relay station to communicate with the broadband side. In this way, the DMR terminal implements roaming from one relay station to another.
It should be understood that, when the DMR terminal leaves the factory, the roaming frequency point list may also be written into the DMR terminal through configuration programming software. When the DMR terminal is started, the DMR terminal may sequentially detect the signal strength of the synchronization signaling of each roaming frequency point according to the roaming frequency point list, so as to determine with which relay station the DMR terminal communicates with the broadband side.
It is understood that the embodiments and examples herein are for illustrative purposes only and that many variations may be made by those skilled in the art, while the scope of the invention is defined by the claims.
