[0034] To make the purpose, technical solutions, and advantages of the embodiments of the present application more clear, each embodiment of the present application will be described in detail below with reference to the accompanying drawings. However, those skilled in the art will appreciate that many technical details are provided in each embodiment of the present application to help readers better understand the present application. However, even without these technical details and various variations and modifications based on the following embodiments, the technical solutions claimed in the present application can still be implemented.

[0035] The following embodiments are divided for the convenience of description and should not constitute any limitation on the specific implementation of the present application. The various embodiments can be combined with each other and referenced to each other under the premise of no contradiction.

[0036] In one aspect, embodiments of the present application provide a DECT-based communication method for use with a mobile terminal. The mobile terminal can be any mobile electronic device capable of implementing the DECT-based communication method of the present application and not deployed in a fixed manner. For example, the mobile terminal can be a DECT cordless handset. It should be noted that the mobile terminal includes a DECT module and a wireless local area network (WLAN) module. The DECT module supports DECT base station services, and the WLAN module supports WLAN services. In other words, the mobile terminal can communicate as both a WLAN terminal and a DECT base station. The DECT module and the WLAN module work together on the mobile terminal to implement the functionality of a DECT base station, making base station equipment no longer a requirement for DECT network deployment. This eliminates the need for base station equipment. Therefore, for users, the DECT system no longer requires the deployment of additional base station equipment in addition to the mobile terminal, reducing the number of network devices required, lowering management costs, and lowering equipment purchase costs. The DECT-based communication method of the present application will be described below in conjunction with various embodiments.

[0037] In some embodiments, as Figure 1 As shown, the DECT-based communication method may include the following steps:

[0038] Step 101: After the base station mode is started, a registration request is sent to the SIP server via the wireless LAN module.

[0039] Step 102: When the registration request is successfully responded, SIP accounts are allocated to the terminal and other mobile terminals registered with the terminal through the DECT module and the wireless LAN module.

[0040] Step 103: Through the DECT module, a call is established between the other mobile terminals registered with the terminal and the SIP server according to the SIP account on the communication connection established with the SIP server and other mobile terminals registered with the terminal.

[0041] Thus, a DECT module supporting DECT base station services and a wireless LAN module supporting wireless LAN services are provided on the mobile terminal, enabling the mobile terminal to communicate with the SIP server via the wireless LAN module and providing SIP account allocation services. This allows the mobile terminal to establish calls between other mobile terminals and the SIP server based on the SIP account, over communication connections established with the SIP server and other mobile terminals. This enables communication between other mobile terminals and between the mobile terminal and external devices within the DECT system. This enables base station services to be implemented through the mobile terminal, thus overcoming reliance on base station equipment. For users, the DECT system no longer requires base stations to be deployed outside the mobile terminal, reducing the number of network devices required, lowering management costs, and lowering equipment purchase costs. Furthermore, the mobility of mobile terminals providing base station functionality eliminates communication range limitations, making communication more flexible and enabling wider application.

[0042] To facilitate better understanding of those skilled in the art Figure 1 The embodiments shown will be explained below.

[0043] In step 101, after the base station mode is activated, a registration request is sent to the SIP server via the wireless LAN module. In the embodiment of the present application, the mobile terminal provides a wireless LAN mode in addition to the base station mode. The base station mode primarily supports DECT base station services via the DECT module, and the wireless LAN mode primarily supports wireless LAN services via the wireless LAN module. The implementation of wireless LANs has been documented in related art and is not limited in the embodiments of the present application. For example, the wireless LAN can be Wi-Fi, etc. Of course, the wireless LAN can also be other types of networks, as long as the network is not a DECT network, and these are not listed here.

[0044] It should be noted that in the embodiment of the present application, the mobile terminal can also support DECT terminal services. When the mobile terminal calls the DECT terminal service, its operation is the same as that of the mobile terminal in the DECT network given in the relevant technology. Since it has been recorded in the relevant technology, it will not be repeated here.

[0045] Thus, in the absence of an available SIP server and / or wireless LAN, the mobile terminal can directly establish a call with another mobile terminal registered with it. In other words, if at least one of the SIP server or wireless LAN required for DECT base station service is unavailable, rendering the DECT base station inoperable, the mobile terminal can still communicate externally as a normal DECT terminal. This makes mobile terminal communication more flexible and provides users with stable, real-time, reliable, and continuous communication services.

[0046] It should be noted that the embodiments of the present application do not limit the method for activating the base station mode. For example, in some embodiments, the mobile terminal may automatically activate the base station mode through a configured policy, thereby executing step 101. The embodiments of the present application do not limit the configured policy. For example, in some embodiments, the mobile terminal may activate the base station mode through a user's operation instruction, etc., which are not listed here one by one.

[0047] In addition, the related art has already described how a device sends a registration request to a SIP service and how SIP performs response processing, and therefore will not be repeated here.

[0048] In step 102, if the registration request is successfully responded to, SIP accounts are allocated to the terminal and other mobile terminals registered with the terminal via the DECT module and the wireless LAN module. It should be understood that only if the registration request is successfully responded to by the terminal can a SIP communication connection be utilized, and only then is a SIP account allocated for establishing a call necessary?

[0049] It should be noted that the embodiments of the present application do not limit the other mobile terminals that have been registered with this terminal. On the one hand, the embodiments of the present application do not limit the number of other mobile terminals that have been registered with this terminal. In some embodiments, the number of other mobile terminals that have been registered with this terminal can be 1, 3, 6, 13, etc. On the other hand, the embodiments of the present application do not limit the types of other mobile terminals that have been registered with this terminal. For example, in some embodiments, the other mobile terminals that have been registered with this terminal can be other mobile terminals that have successfully registered with this terminal within a certain period of time in the past. For another example, in some embodiments, the other mobile terminals that have been registered with this terminal can also be all other mobile terminals that have successfully registered with this terminal in the past. For another example, in some embodiments, the other mobile terminals that have been registered with this terminal can also be other mobile terminals that have successfully registered with this terminal during the last time this terminal was in base station mode, etc., and they will not be listed one by one here.

[0050] It should also be noted that the embodiments of this application do not limit the method for allocating SIP accounts. For example, in some embodiments, SIP account allocation is achieved by having another mobile terminal already registered with the current terminal initiate a SIP registration again. In this case, the SIP registration process is well documented in the relevant art and will not be detailed here. In some other embodiments, SIP account allocation is achieved by reusing a SIP account previously used by another mobile terminal already registered with the current terminal, and so on. These methods are also not listed here.

[0051] In some embodiments, to further improve efficiency, SIP accounts are assigned to other mobile terminals registered with the terminal via the DECT module and the wireless LAN module. This can be achieved by determining the registration information of the terminal and other mobile terminals registered with the terminal from locally stored registration information; and assigning SIP accounts to the terminal and other mobile terminals registered with the terminal based on the registration information via the DECT module. In other words, SIP accounts are assigned using historical registration information, improving efficiency. Furthermore, the registration information is stored by the mobile terminal, enabling rapid retrieval of the registration information and completing SIP account assignment. This reduces call setup latency, shortens user wait times, and improves user experience.

[0052] It should be noted that in the embodiment of the present application, the terminal also needs to be assigned a SIP account. In this way, it can communicate with the SIP server based on the SIP account of the terminal, so that the connection with the SIP server can be better managed in a unified manner and the processing pressure of the SIP server can be reduced.

[0053] In step 103, a call is established between the other mobile terminals registered with the terminal and the SIP server based on the SIP account, using the DECT module and the wireless local area network module. The communication connection established with the SIP server and other mobile terminals registered with the terminal, i.e., the call established by the terminal as a base station, consists of two parts: a SIP communication connection established between the terminal and the SIP server, and a DECT communication connection established between the terminal and other mobile terminals registered with the terminal. Based on these connections, the communication connection between the other mobile terminals and the SIP server is successfully established. Devices outside the DECT network can establish a connection using the SIP account registered on the SIP server and communicate with mobile terminals in the DECT network, enabling the terminal to provide services provided by DECT base stations as described in related art. In other words, the base station functionality is implemented within the DECT network based on the mobile terminal, thereby overcoming the reliance on base stations and eliminating the need for DECT base stations in the DECT network.

[0054] To facilitate those skilled in the art to better understand the DECT base station function implemented on the mobile terminal in the embodiment of the present application, exemplary descriptions will be provided below in conjunction with a call initiation scenario and a call response scenario.

[0055] In some embodiments, in conjunction with the call initiation scenario, at this time, as Figure 2 As shown, the DECT-based communication method may include the following steps:

[0056] Step 201: After the base station mode is started, a registration request is sent to the SIP server via the wireless LAN module.

[0057] Step 202: If the registration request is successfully responded to, a SIP account is allocated to the terminal and other mobile terminals registered with the terminal through the DECT module.

[0058] Step 203: Receive a call request sent by other mobile terminals registered with the terminal through the DECT module, so as to establish a DECT communication connection with the other mobile terminals registered with the terminal.

[0059] Step 204: Send a call request to the SIP server through the wireless LAN module according to the SIP account of the other mobile terminal that has registered with the terminal and sends the call request, so as to establish a SIP communication connection with the SIP server.

[0060] Step 205 , associate the DECT communication connection established with the other mobile terminal that has sent the call request and the SIP communication connection established based on the SIP account of the other mobile terminal that has sent the call request and has been registered with the terminal.

[0061] From this it is not difficult to see that Figure 2 The embodiment shown is actually Figure 1 On the basis of the illustrated embodiment, a call is established between the other mobile terminals registered with the terminal and the SIP server based on the SIP account on the communication connection established with the SIP server and other mobile terminals registered with the terminal in the following manner: a call request sent by the other mobile terminals registered with the terminal is received through the DECT module to establish a DECT communication connection with the other mobile terminals registered with the terminal; a call request is sent to the SIP server through the wireless LAN module based on the SIP account of the other mobile terminal registered with the terminal that sends the call request to establish a SIP communication connection with the SIP server; and the DECT communication connection established with the other mobile terminals registered with the terminal that sends the call request is associated with the SIP communication connection established based on the SIP account of the other mobile terminal registered with the terminal that sends the call request.

[0062] In this way, after associating the corresponding communication connections, it is possible to distinguish the communication connections of different mobile terminals to avoid interference between their communication processes, and to achieve more concise and efficient mobile terminal management through the management of the association relationship, which can further reduce management costs.

[0063] To facilitate better understanding of those skilled in the art Figure 2The steps of the embodiment shown are explained below. Steps 201 and 202 are substantially the same as steps 101 and 102 of the above embodiment, and are not described in detail here.

[0064] In step 203, a call request sent by another mobile terminal registered with the terminal is received through the DECT module to establish a DECT communication connection with the other mobile terminal registered with the terminal. The embodiment of the present application does not limit the receiving scenario of call requests sent by other mobile terminals registered with the terminal. The terminal may receive only one call request at a time or may receive multiple concurrent call requests simultaneously. The concurrent call requests may come from different mobile terminals or from the same mobile terminal. The initiation of call requests by a mobile terminal and the processing of the call requests have been described in the related art and will not be further elaborated here.

[0065] It should be noted that, for the process of other mobile terminals initiating call requests, the present mobile terminal (the mobile terminal providing base station functions) establishes DECT communication with other mobile terminals to support the call requests sent by the mobile terminals.

[0066] In step 204, a call request is sent to the SIP server via the wireless local area network module based on the SIP account of the other mobile terminal that has registered with the terminal, thereby establishing a SIP communication connection with the SIP server. The call request sent to the SIP server is initiated based on the SIP account of the corresponding mobile terminal. This is primarily to distinguish different mobile terminals on the SIP server side, so that requests initiated by different mobile terminals can be distinguished through different SIP communication connections, thereby avoiding mutual interference and facilitating management. Of course, in some embodiments, the SIP server side may not distinguish the SIP accounts of different mobile terminals, but only distinguish them based on the SIP account on the terminal itself. This can reduce the processing pressure on the SIP server, etc., and will not be listed here.

[0067] In step 205, the DECT communication connection established with the other mobile terminal that has registered with the terminal and sent the call request is associated with the SIP communication connection established based on the SIP account of the other mobile terminal that has registered with the terminal and sent the call request. The embodiments of the present application do not limit the manner in which the communication connections are associated. For example, in some embodiments, this can be achieved by establishing a mapping table, such as by storing tags of associated communication connections under the same keyword (key). In addition, the embodiments of the present application do not limit the execution of the communication connection association action. It can be implemented by other modules present in the mobile terminal, such as a central processing unit, or by associating at least one of the DECT module and the wireless local area network module. These will not be listed here one by one.

[0068] In some embodiments, in conjunction with the call response scenario, at this time, as Figure 3 As shown, the DECT-based communication method may include the following steps:

[0069] Step 301: After the base station mode is started, a registration request is sent to the SIP server via the wireless LAN module.

[0070] Step 302: If the registration request is successfully responded to, a SIP account is allocated to the terminal and other mobile terminals registered with the terminal through the DECT module.

[0071] Step 303: Receive the call request sent by the SIP server through the wireless local area network module to establish a SIP communication connection with the SIP server.

[0072] Step 304: paging other mobile terminals registered with the terminal and corresponding to the called SIP account via the DECT module to establish a DECT communication connection with the paged other mobile terminals registered with the terminal.

[0073] Step 305: associate the DECT communication connection established with the other mobile terminals that are paged and registered with the terminal with the SIP communication connection established by the call request sent by the SIP server.

[0074] From this it is not difficult to see that Figure 3 The embodiment shown is actually Figure 1On the basis of the illustrated embodiment, a call is established between other mobile terminals registered with the terminal and the SIP server based on SIP accounts on the communication connections established with the SIP server and other mobile terminals registered with the terminal in the following manner: a call request sent by the SIP server is received through the wireless LAN module to establish a SIP communication connection with the SIP server; other mobile terminals registered with the terminal corresponding to the called SIP account are paged through the DECT module to establish a DECT communication connection with the paged other mobile terminals registered with the terminal; and the DECT communication connection established with the paged other mobile terminals registered with the terminal is associated with the SIP communication connection established by the call request sent by the SIP server.

[0075] It is not difficult to see that Figure 3 The embodiment shown is Figure 2 The steps of the illustrated embodiments are the same except for the objects initiating the processes, so they will not be described in detail here.

[0076] In this way, after associating the corresponding communication connections, it is possible to distinguish the communication connections of different mobile terminals to avoid interference between their communication processes, and to achieve more concise and efficient mobile terminal management through the management of the association relationship, which can further reduce management costs.

[0077] It should be noted that the above embodiment only provides relevant explanations based on the example of a mobile terminal processing other mobile terminals registered with the terminal when entering base station mode. In some embodiments, the DECT-based communication method further includes: receiving registration requests from other mobile terminals not registered with the terminal; allocating SIP accounts to the other mobile terminals not registered with the terminal based on the registration requests; and establishing a call between the other mobile terminals not registered with the terminal and the SIP server based on the SIP accounts over the communication connections established with the SIP server and the other mobile terminals not registered with the terminal. In other words, the terminal opens registration permissions to support new mobile terminal registrations, making communication more flexible and covering a wider range.

[0078] In some embodiments, in order to facilitate those skilled in the art to better understand the DECT-based communication method provided in the above embodiments, the following will be combined with Figure 4 The following scenario is used as an example. Figure 4As shown, in a wireless local area network formed by a certain Wi-Fi network, there are mobile terminals (DECT mobile phone (base station mode) and DECT mobile phone 1) located within the coverage of the Wi-Fi network, and the DECT mobile phone (base station mode) has the ability and authority to access the access point (Wi-Fi AP) of the Wi-Fi network. At the same time, there are mobile terminals (DECT mobile phone 2, ..., DECT mobile phone N) outside the coverage of the Wi-Fi network. The DECT mobile phone (base station mode), DECT mobile phone 1, DECT mobile phone 2, ..., DECT mobile phone N are all within the coverage of the same DECT network. In order to better support communication with the SIP server, it is assumed that the Wi-Fi AP and the SIP are connected via a wired network. The connection method of the wired network is not limited here. It can be copper wire, optical fiber, etc., and they will not be listed one by one here.

[0079] exist Figure 4 In the scenario shown, the DECT-based communication method may involve the following:

[0080] Step S101: The user selects DECT base station mode through a menu interface on the DECT mobile phone.

[0081] Step S102: The DECT mobile phone (base station mode) loads the DECT base station software.

[0082] Step S103: The DECT mobile phone (base station mode) turns on the Wi-Fi module to maintain the Wi-Fi network connection.

[0083] Step S104: The DECT phone (base station mode) starts the SIP software to register a SIP account with the SIP server.

[0084] Step S105: If DECT phone 1, DECT phone 2, etc. have been registered with this DECT base station before, the registration information of these phones is written to the DECT phone (base station mode), and the DECT phone (base station mode) opens the new phone registration mode of the DECT base station.

[0085] In this way, other DECT phones that have been registered to the DECT phone (base station mode) before will be automatically registered to this base station after the DECT base station software is started; other DECT phones that have not yet been registered to the DECT phone (base station mode) will complete the registration through their base station registration interface.

[0086] Step S106: The DECT phone (base station mode) assigns a corresponding SIP account to the corresponding DECT phone according to the registered manual number and configuration information in the registration information. At the same time, the DECT phone (base station mode) is also assigned a SIP account.

[0087] In this way, all mobile phones can perform VoIP communication with devices outside the DECT network through the DECT mobile phone (base station mode).

[0088] Step S107: When other DECT mobile phones make an outgoing call, they first establish a DECT communication connection with the DECT mobile phone (base station mode) through a call.

[0089] Step S108: The DECT mobile phone (base station mode) establishes a SIP connection with the SIP server according to the number dialed by the other DECT mobile phone (involving a SIP account).

[0090] Step S109: The DECT base station associates the SIP communication connection with the DECT call.

[0091] In this way, the two-way RTP voice code stream of the call on the SIP communication connection can be connected to the DECT call to achieve the purpose of two-way communication.

[0092] Step S110: When the SIP software of the DECT phone (base station mode) receives a SIP call from the outside, the DECT phone (base station mode) pages the corresponding DECT phone according to the SIP account configuration, establishes a DECT call with the DECT base station and rings.

[0093] Step S111: After the ringing DECT phone answers, the DECT base station associates the SIP communication connection with the incoming call with the DECT communication connection.

[0094] Similar to the above, the purpose of two-way communication can also be achieved by responding to the call.

[0095] As can be seen from the above example, the DECT phone and DECT base station are combined into one, fully utilizing the hardware resources on the phone. Through flexible software configuration, users can flexibly deploy, saving customers' hardware procurement and management costs.

[0096] It should be noted that in the above example, the other DECT mobile phone may be a DECT mobile phone that does not have DECT base station functionality. That is, in some embodiments, at least one of the other mobile terminals registered with the terminal supports base station mode, or none of the other mobile terminals registered with the terminal supports base station mode.

[0097] It should also be noted that a DECT communication system may also involve a repeater, which can serve as an intermediary between a terminal and a base station, thereby expanding the coverage of the base station. Based on this, in some embodiments, the DECT module also supports a DECT relay service. Accordingly, the DECT-based communication method further includes: in repeater mode, pairing with a base station device so that other mobile terminals can establish a call with the paired base station device through the terminal, wherein the base station device includes a DECT base station and / or other terminals in base station mode.

[0098] At this time, in repeater mode, the mobile terminal acts as a bridge between the original base station and other terminals. It establishes communication with the original base station and other terminals at the same time, and forwards the call voice and control information between the terminal and the base station to the other party, thereby expanding the coverage of the base station.

[0099] In some embodiments, when the DECT terminal is configured in repeater mode, assuming that the DECT terminal is a DECT mobile phone, the DECT-based communication method may include the following steps:

[0100] Step S111: The user selects the repeater mode through the menu interface on the DECT mobile phone.

[0101] Step S112: The DECT mobile phone (repeater mode) loads the DECT repeater software.

[0102] Step S113: When the DECT mobile phone (repeater mode) is placed at an appropriate location, the DECT mobile phone (repeater mode) will be paired with the base station device based on the DECT repeater software.

[0103] Step S114: establishing a call between the paired base station device and other terminals.

[0104] In this way, the DECT mobile phone (repeater mode) can extend the coverage of the base station equipment, and other DECT mobile phones can communicate with the base station equipment through the DECT mobile phone (repeater mode).

[0105] It is not difficult to find that the above embodiments are mainly for DECT communication solutions based on VoIP technology. When the mobile terminal provides the functions provided by the DECT base station, the embodiments of the present application also support communication methods within the DECT network, especially supporting duplex intercom communication solutions. For details, please refer to the following embodiments:

[0106] In some embodiments, as Figure 5 As shown, the DECT-based communication method may include the following steps:

[0107] Step 501: In base station mode, receive an intercom call request from another mobile terminal that has registered with the current terminal.

[0108] Step 502: On the communication connection established with other mobile terminals registered with this terminal, according to the intercom call request, a full-duplex intercom call is established between this terminal and / or other mobile terminals registered with this terminal, and other mobile terminals registered with this terminal that initiate the intercom call request.

[0109] In this way, the mobile terminal supports the DECT base station service. Therefore, in base station mode, after receiving a call request from another mobile terminal registered with the terminal, the mobile terminal can establish a call between the other mobile terminals registered with the terminal based on the received call request on the communication connection established with the other mobile terminals registered with the terminal. In other words, communication between the other mobile terminals is supported, that is, the service provided by the base station is realized through the mobile terminal, thus overcoming the dependence on the base station. For users, the DECT system no longer requires the deployment of base stations outside the mobile terminal, reducing the number of network devices required to be deployed, reducing management costs, and reducing the cost of purchasing equipment. In addition, the mobility of mobile terminals that provide base station functions breaks the limitation of communication range, making communication more flexible and applicable to a wider range of applications.

[0110] To facilitate better understanding of those skilled in the art Figure 5 The embodiment shown is described below and its steps are explained.

[0111] In step 501, in base station mode, an intercom call request is received from another mobile terminal that has been registered with the terminal. The embodiment of the present application does not limit the other mobile terminal that initiates the intercom call request. The process of a mobile terminal initiating an intercom call request has been described in related art and will not be further elaborated here.

[0112] In step 502, based on the intercom call request, a full-duplex intercom call is established between the terminal and / or other mobile terminals registered with the terminal, and the other mobile terminals registered with the terminal that initiated the intercom call request, over the communication connections established with other mobile terminals registered with the terminal. It will be appreciated that the terminal, acting as a base station, obtains registration information of relevant mobile terminals and, when necessary (i.e., when other mobile terminals have a call request), can page them based on the registration information and establish a call. Paging and call establishment are already described in the relevant art and will not be further elaborated here.

[0113] It should be noted that the embodiments of the present application do not limit the method for determining the mobile terminal that needs to establish a full-duplex intercom call. For example, in some embodiments, the terminal may pre-store group information of terminals that need to conduct multi-party communication. When a call request from a mobile terminal in the group is received, the multi-party communication of the group is triggered. For example, in some embodiments, the mobile terminal that initiates the call request may carry the identifier of the mobile terminal that needs to participate in the meeting in the request, and establish a call for the corresponding mobile terminal based on the identifier in the request to form the corresponding multi-party communication. Of course, the above are only examples. In some embodiments, other implementation methods may also be used, which will not be listed here one by one.

[0114] It should also be noted that the embodiments of the present application do not limit the method for establishing a full-duplex intercom call. As described in the aforementioned embodiments, it can be achieved by associating connections. For example, in some embodiments, the establishment of a full-duplex intercom is achieved by associating communication connections between the terminal participating in the full-duplex intercom and / or other mobile terminals registered with the terminal. In this case, the communication connections that need to be associated, as described above, can directly carry corresponding information based on the call request, or can be pre-recorded information that is triggered by the intercom call request, etc., and will not be further described here.

[0115] In addition, the embodiment of the present application does not limit the mobile terminal participating in the full-duplex intercom call. It may include this terminal or may not include this terminal, etc., and will not be described in detail here.

[0116] It is also understandable that there may be a need for new users to join the call during multi-party communication. Figure 6 As shown, the DECT-based communication method may include the following steps:

[0117] Step 601: In base station mode, receive an intercom call request from another mobile terminal that has registered with the current terminal.

[0118] Step 602: On the communication connection established with other mobile terminals registered with this terminal, according to the intercom call request, a full-duplex intercom call is established between this terminal and / or other mobile terminals registered with this terminal, and other mobile terminals registered with this terminal that initiate the intercom call request.

[0119] Step 603: Receive an intercom call request from another mobile terminal that is not currently participating in the full-duplex intercom call and has been registered with the terminal.

[0120] Step 604: On the communication connection established with other mobile terminals registered with this terminal, a full-duplex intercom call is established between other mobile terminals registered with this terminal that are not currently participating in the full-duplex intercom call and other mobile terminals registered with this terminal that are participating in the full-duplex intercom call.

[0121] Thus, based on the aforementioned embodiment, a solution for a new mobile terminal to participate in a call is further provided, making communication more flexible and convenient, and being conducive to further improving the user experience.

[0122] It is not difficult to find that step 601-step 602 is substantially the same as step 501-step 502 of the aforementioned embodiment, and step 603-step 604 is the same as step 501-step 502 of the aforementioned embodiment, and they will not be described one by one here.

[0123] To facilitate those skilled in the art to better understand the above embodiment, the communication process will be described below with reference to a specific message exchange process after a call is established.

[0124] In some embodiments, as Figure 7 As shown, the DECT-based communication method may include the following steps:

[0125] Step 701: In base station mode, receive an intercom call request from another mobile terminal that has registered with the current terminal.

[0126] Step 702: On the communication connection established with other mobile terminals registered with this terminal, according to the intercom call request, a full-duplex intercom call is established between this terminal and / or other mobile terminals registered with this terminal, and other mobile terminals registered with this terminal that initiate the intercom call request.

[0127] Step 703: Receive a voice message sent by another mobile terminal that is registered with the terminal and participates in the full-duplex intercom call.

[0128] Step 704: Send a voice message to other mobile terminals registered with the terminal that are not voice message senders and that participate in the full-duplex intercom call through the associated communication connection.

[0129] In this way, by sending a voice message sent by a mobile terminal to other mobile terminals in the associated communication connection, multi-party conferences can be supported, which is conducive to enriching communication methods and improving user experience.

[0130] In some embodiments, while receiving a voice message sent by another mobile terminal that has been registered with the terminal, the DECT-based communication method further includes: receiving a voice message sent by another mobile terminal that has been registered with the terminal and is participating in a full-duplex intercom call; and / or sending a voice message to another mobile terminal that has been registered with the terminal and is participating in a full-duplex intercom call. In other words, by utilizing current DECT mobile terminals to implement full-duplex intercom functionality, no additional DECT base station is required, making it convenient to carry and use outdoors. Users can use existing DECT mobile terminals for duplex intercom, achieving a one-machine-multiple-purposes effect, saving users' hardware procurement costs. In particular, it overcomes the problem of limited communication range caused by the fixed location of base stations, supporting DECT-based full-duplex intercom calls over a wider range, and having greater applicability.

[0131] In some embodiments, to enhance user convenience and avoid issues such as accidental touches, the collection and sending of voice messages on other mobile terminals registered with the current terminal can be configured to be triggered by the user's intercom button press. This allows for more convenient and reliable intercom operations through clear operations, improving the user experience.

[0132] In some embodiments, the mobile terminal further supports DECT terminal services. Correspondingly, the DECT-based communication method further includes: switching between a base station mode and a terminal mode, wherein in the terminal mode, the DECT terminal service is called.

[0133] In some embodiments, in base station mode, before receiving an intercom call request from another mobile terminal registered with the terminal, the DECT-based communication method further includes: loading a DECT base station service in response to a user instruction to enter base station mode. In other words, entering base station mode in response to a user's instruction makes base station mode more stable and controllable, providing a better user experience.

[0134] In some embodiments, at least one of the other mobile terminals registered with the terminal supports base station mode, or none of the other mobile terminals registered with the terminal supports base station mode. In other words, the embodiments of the present application do not limit the mobile terminals that can participate in a full-duplex intercom call. As long as there is a mobile terminal that supports DECT base station service, a multi-party full-duplex intercom call can be achieved within any location range, which has fewer restrictions, greater adaptability, and more flexible applications.

[0135] In order to facilitate those skilled in the art to better understand the DECT-based communication method provided in the above embodiment, the following will be combined with Figure 8 The following scenario is used to illustrate the situation. Figure 8As shown, in a DECT network, there are mobile terminals providing base station services (ie, DECT mobile phones (base station mode)), and other mobile terminals (DECT mobile phone 1, ..., DECT mobile phone N).

[0136] At this point, each device in the DECT network involves the following operations:

[0137] Step S201: The DECT mobile phone (base station mode) selects the DECT base station mode through the menu interface.

[0138] Step S202: The DECT mobile phone (base station mode) loads the DECT base station software.

[0139] Step S203: DECT mobile phone 1, ..., DECT mobile phone N are registered to the DECT mobile phone (base station mode) respectively.

[0140] Step S204: The DECT phone (base station mode) or one of DECT phones 1, ..., DECT phones N initiates an intercom call by key operation.

[0141] Step S205: After receiving the intercom call request, the DECT mobile phone (base station mode) initiates paging with all mobile phones participating in the intercom among DECT mobile phone 1, ..., DECT mobile phone N, and establishes a multi-party conference system.

[0142] Step S206: When one of DECT mobile phones 1, ..., DECT mobile phones N needs to talk, the collecting user presses the talk button to start voice talk, and sends the collected voice message to the corresponding mobile phone of DECT mobile phone 1, ..., DECT mobile phone N through the DECT mobile phone (base station mode), thereby realizing talk.

[0143] When the intercom ends, the user releases the intercom button to end the current intercom process.

[0144] Step S207: When other mobile phones are talking on each other, if another mobile phone also needs to talk on each other, the user can join the intercom call by directly pressing the intercom key.

[0145] In this way, the DECT network supports multi-party conferencing systems, allowing multiple people to talk to each other at the same time. The only difference from the multi-party conferencing system is that when one party needs to speak, they need to press the intercom button to talk.

[0146] It is not difficult to find from the above examples that the embodiments of the present application provide for integrating a DECT base station into a DECT mobile terminal. The DECT mobile phone has both mobile phone and DECT base station functions and can be moved together with other DECT mobile phones for intercom, thereby solving the limitation of the use range of the full-duplex intercom function using DECT technology and can be used indoors or outdoors.

[0147] It should also be noted that the above embodiments describe DECT-based communication methods from the perspectives of communicating with devices outside the DECT network and communicating within the DECT network. However, this does not mean that only one of the two communication methods must be used. In some embodiments, a mobile terminal can simultaneously indicate communication with devices outside the DECT network and communication within the DECT network. For example, in some examples, after receiving a call request from another mobile terminal registered with the terminal in base station mode, the DECT-based communication method further includes the following steps: establishing a call between the other mobile terminal registered with the terminal and the SIP server based on the SIP account assigned to the other mobile terminal registered with the terminal, over a communication connection established with the SIP server and the other mobile terminal registered with the terminal. Whether the call is established through the SIP server can be determined based on the call destination indicated in the call request initiated by the other mobile terminal, or the call request can include a special field that can indicate whether communication is to be conducted externally or within the DECT network. Of course, the above are merely examples of the above-mentioned embodiments. In some embodiments, other combinations can be used, which will not be detailed here.

[0148] It should also be noted that the above description does not mean that the mobile terminal only supports base station mode. It is understood that the base station mode can be entered as needed. In some embodiments, in addition to base station mode, the mobile terminal can also support the operation mode of a general DECT terminal and / or support wireless local area network communication. These will be described below in conjunction with relevant embodiments.

[0149] In some embodiments, as Figure 9 As shown, the communication method based on DECT and wireless local area network includes the following steps:

[0150] Step 901: Check whether there is an available base station in the current DECT network. An available base station is another mobile terminal currently in base station mode and registered with the terminal, or a DECT base station device. If yes, proceed to step 902; if not, proceed to step 903.

[0151] Step 902: Establish a call with other mobile terminals in the current DECT network or devices outside the current DECT network that are registered on the available base station through the available base station.

[0152] Step 903: Access the wireless local area network according to the configuration information of the wireless local area network, and establish a call through the wireless local area network.

[0153] In this way, by detecting whether there are available base stations in the current DECT network, where available base stations are other mobile terminals currently in base station mode and with which the terminal has registered, or DECT base station devices, the terminal can establish a call through the available base station with other mobile terminals in the current DECT network or devices outside the current DECT network that are registered with the available base station. Alternatively, if no base station is available, the terminal can access the wireless local area network based on wireless local area network configuration information and establish a call through the wireless local area network. This allows DECT communication services to be provided by the mobile terminal as a base station, rather than being limited to the DECT base station device itself, thus overcoming reliance on base stations. For users, the DECT system no longer requires the deployment of base stations outside the mobile terminal, reducing the number of network devices required, lowering management costs, and lowering equipment purchase costs. Furthermore, the ability to automatically select a communication mode makes communication more secure and stable, improving communication quality.

[0154] In some embodiments, as Figure 10 As shown, the communication method based on DECT and wireless local area network includes the following steps:

[0155] Step 1001: Check whether there is an available base station in the current DECT network. An available base station is another mobile terminal currently in base station mode and registered with the terminal, or a DECT base station device. If yes, proceed to step 1002; if not, proceed to step 1003.

[0156] Step 1002: Detect the signal quality of the available base stations to determine whether it meets the first preset condition. If so, perform step 1004; if not, perform step 1003.

[0157] Step 1003: Access the wireless local area network according to the configuration information of the wireless local area network, and establish a call through the wireless local area network.

[0158] Step 1004: Establish a call with other mobile terminals in the current DECT network or devices outside the current DECT network that are registered on the available base station through the available base station.

[0159] In this way, based on the above-mentioned embodiment, base station quality detection is further provided, so that the base station will be used for communication only when the first preset condition is met, thereby avoiding low-quality communication using the base station when the base station quality is poor, and ensuring the quality of communication.

[0160] It should be noted that the embodiment of the present application does not limit the first preset condition. It can limit different aspects of the available base stations according to application scenarios, user needs, etc., such as limiting the signal strength, signal-to-noise ratio, etc. of the available base stations, which will not be repeated here.

[0161] Based on requirements similar to those of the aforementioned embodiment, the quality of the wireless LAN can also be tested to ensure the quality of communication. That is, before accessing the wireless LAN according to the configuration information of the wireless LAN, the communication method based on DECT and the wireless LAN also includes: detecting the signal quality of the wireless LAN. Correspondingly, accessing the wireless LAN according to the configuration information of the wireless LAN is achieved in the following manner: when the quality of the wireless LAN meets the second preset condition, accessing the wireless LAN according to the configuration information of the wireless LAN, and establishing a call through the wireless LAN. It should be noted that the embodiment of the present application does not limit the second preset condition. It can limit different aspects of the wireless LAN according to the application scenario, user needs, the type of wireless LAN, etc., such as limiting signal strength, signal-to-noise ratio, coverage range, etc., which will not be repeated here.

[0162] It is also understood that the quality of the wireless LAN or available base stations may change as a call progresses. Based on this, in some embodiments, after detecting the signal quality of the wireless LAN, the communication method based on DECT and the wireless LAN further includes: if the quality of the wireless LAN does not meet the second preset condition, returning to detecting whether there are available base stations in the current DECT network. In other words, if the wireless LAN is unavailable, DECT communication is attempted.

[0163] It should be noted that the current mode can also be adjusted during the process of accessing a wireless local area network or providing services as a base station in a DECT network. For example, in some embodiments, according to the configuration information of the wireless local area network, after accessing the wireless local area network, the communication method based on DECT and the wireless local area network further includes: returning to execute, through the wireless local area network, a detection of whether there is an available base station in the current DECT network. That is, in the wireless local area network, an attempt is made to connect to an available base station to switch the communication mode, enter the DECT network, and conduct DECT-based communication. Of course, when providing services as a base station in a DECT network, or when communicating as an ordinary mobile terminal in a DECT network, the quality of the wireless local area network can also be detected, thereby switching to accessing the wireless local area network for communication, etc. This can be set according to needs and will not be described in detail here.

[0164] It should also be noted that the registration status of the mobile terminal with another mobile terminal currently in base station mode is achieved by initiating registration. That is, in some embodiments, the communication method based on DECT and a wireless local area network further includes sending a registration request to the other mobile terminal currently in base station mode to register with the other mobile terminal currently in base station mode. This allows the mobile terminal to initiate the registration, making the communication method more controllable and the user experience better.

[0165] After initiating registration, in order to achieve communication using a mobile terminal supporting DECT base station services as described in the aforementioned embodiment, after sending a registration request to another mobile terminal currently in base station mode, the communication method based on DECT and a wireless local area network further includes: receiving a SIP account number issued by the other mobile terminal currently in base station mode if the registration request is successfully responded to; and initiating registration with a SIP server based on the SIP account number. This allows both registration and SIP account allocation to be completed on the other mobile terminal in base station mode, and registration on the SIP server using the SIP account number. Subsequently, when using DECT communication, the SIP account number can be used to establish a communication path from one mobile terminal to another, maintaining high-quality calls.

[0166] Furthermore, it is understood that registration is not guaranteed to succeed. In some embodiments, registration failure may also be considered. In this case, after sending a registration request to another mobile terminal currently in base station mode, the communication method based on DECT and a wireless LAN further includes: if a response to the registration request fails, accessing the wireless LAN according to the configuration information of the wireless LAN and establishing a call via the wireless LAN. This ensures that communication can always be carried out using an available network, providing users with stable, reliable, and high-quality calls.

[0167] It should be noted that the situation where the registration request response fails may be a failure in SIP account allocation, or other mobile terminals in base station mode refuse to register, or a failure to register with the SIP server, or two or all of the above situations, etc., which will not be listed here one by one.

[0168] It should be noted that registration failure is only one possible scenario; another possible scenario is that no other mobile terminals in base station mode that can be registered are found. That is, in some embodiments, before sending a registration request to other mobile terminals currently in base station mode, the communication method based on DECT and a wireless local area network further includes detecting whether other mobile terminals currently in base station mode exist. Accordingly, sending a registration request to other mobile terminals currently in base station mode can be implemented as follows: if other mobile terminals currently in base station mode exist, sending a registration request to the other mobile terminals currently in base station mode.

[0169] Of course, it is also understandable that when there are no other mobile terminals currently in base station mode, you can continue to check whether there is a base station device. If there is no base station device, you can only use the wireless LAN to make calls, etc., and we will not list each of the different situations here.

[0170] In order to facilitate those skilled in the art to better understand the DECT-based communication method provided in the above embodiment, the following will be combined with Figure 11 The process shown in FIG. 1 illustrates the detection and mode switching during the process of a mobile terminal starting up and entering the network for communication. Figure 11 As shown, there is a wireless LAN (whose coverage is the communication coverage provided by Wi-Fi AP) and a DECT network (whose coverage is the communication coverage provided by DECT base station (device)), wherein DECT mobile phone 1 is only located in the coverage of the wireless LAN, DECT mobile phone 2 is located in the coverage of the wireless LAN and the DECT network, and DECT mobile phone 3 is only located in the coverage of the DECT network.

[0171] At startup, DECT phone 1, DECT phone 2, and DECT phone 3 all perform the following operations: Figure 12 The following processing is shown:

[0172] Step S301: Registering to a DECT base station.

[0173] Step S302: Setting up a Wi-Fi network.

[0174] Step S303: Allocate a SIP account to the mobile phone and register it with the SIP server.

[0175] Step S304: Check the signal of the surrounding registered DECT base stations. If the DECT signal is good, the mobile phone turns off Wi-Fi and enters DECT mode to communicate only using DECT. If the signal of the registered DECT base station is poor or non-existent, execute step S305.

[0176] Step S305: Check the surrounding Wi-Fi networks. If there is a configured Wi-Fi network, connect to the Wi-Fi network and the mobile phone enters Wi-Fi mode to communicate using the Wi-Fi network. If there is no configured Wi-Fi network, execute step S304.

[0177] Step S306: The mobile phone checks whether the DECT base station it has registered with exists through the Wi-Fi network. If it finds the registered DECT base station, step S304 is executed.

[0178] Step S306: If no registered DECT base station is found, the mobile phone remains in Wi-Fi mode. If the Wi-Fi signal is lost, step S304 is executed.

[0179] Based on the above processing, DECT mobile phone 1 will be able to communicate based on the wireless LAN, DECT mobile phone 2 can communicate based on the wireless LAN or communicate as an ordinary terminal in the DECT network (at this time, due to the existence of a DECT base station, DECT mobile phone 2 may not work in base station mode. If there is no DECT base station, DECT mobile phone 2 can choose to enter base station mode to provide base station services for DECT mobile phone 3), DECT mobile phone 3 can register to the DECT base station and communicate as an ordinary terminal in the DECT network.

[0180] It should be noted that in the above example, the Wi-Fi mode means accessing the Wi-Fi network, and entering the DECT mode means working as an ordinary mobile terminal in the DECT network. Of course, it can also be entering the base station mode of the aforementioned embodiment, which will not be described here one by one.

[0181] It should also be noted that the above examples do not further describe the further processing after entering Wi-Fi mode or DECT mode, but this does not mean that subsequent processing will not be performed. For example, after entering DECT mode, it is still possible to detect whether to enter base station mode, or after entering Wi-Fi mode, it is possible to further enter base station mode as described in the above embodiment based on the Wi-Fi network, etc., and these will not be described in detail here.

[0182] In addition, for ease of understanding, the above embodiment describes the first preset condition and the second preset condition as a good signal. Of course, this is only an example. In some embodiments, they can also be configured according to application scenarios, user needs, etc., and will not be described in detail here.

[0183] The steps of the various methods above are divided only for the purpose of clear description. During implementation, they can be combined into one step or some steps can be split and decomposed into multiple steps. As long as they include the same logical relationship, they are all within the scope of protection of this patent. Adding insignificant modifications or introducing insignificant designs to the algorithm or process without changing the core design of the algorithm and process are all within the scope of protection of this patent.

[0184] A second aspect of the embodiments of the present application further provides a communication device. The communication device provided in the embodiments of the present application is to support the DECT-based communication method (or the communication method based on DECT and a wireless local area network) provided in the above embodiments. It will be understood that due to different supported communication methods, the communication device may have different components.

[0185] In some embodiments, as Figure 13 As shown, the communication device may include: a HOST MCU, and a DECT module and a wireless LAN communication module ( Figure 13 The Wi-Fi module is used as an example of a wireless LAN communication module, which does not mean that the wireless LAN communication module can only refer to the Wi-Fi module), memory, Flash ( Figure 13 The memory and Flash are used as examples of storage modules, which does not mean that the storage modules can only be memory and Flash); the DECT module and the wireless LAN communication module are also connected to antennas respectively, and the HOST MCU also supports connecting to devices other than communication devices, including keyboards, batteries, and LCD screens ( Figure 13 The LCD screen is used as an example of a display module, which does not mean that the display screen can only be an LCD screen).

[0186] It should be noted that Figure 13 For example only, in some embodiments, the device other than the communication device may also include one or more of the following devices: a keyboard, a battery, and a display screen, rather than all of them, or only include these three items, which are not listed here one by one.

[0187] It should also be noted that Figure 13 This is just an example. In some embodiments, the DECT module and the wireless local area network module may also share an antenna, etc., which will not be described in detail here.

[0188] In the structural diagram of the communication equipment Figure 13 As shown, the system architecture corresponding to the communication equipment is as follows Figure 14 shown.

[0189] In some embodiments, as Figure 15As shown, the communication device may further include: a HOST MCU, and a DECT module, a memory, a Flash ( Figure 15 The memory and Flash are used as examples of storage modules, which does not mean that the storage modules can only be memory and Flash); the DECT module is also connected to the antenna, and the HOST MCU also supports connecting to devices other than communication devices, including keyboards, batteries, and LCD screens ( Figure 15 The LCD screen is used as an example of a display module, which does not mean that the display screen can only be an LCD screen).

[0190] It should be noted that Figure 15 For example only, in some embodiments, the device other than the communication device may also include one or more of the following devices: a keyboard, a battery, and an LCD screen, rather than all of them, or only include these three items, which are not listed here one by one.

[0191] In the structural diagram of the communication equipment Figure 15 As shown, the system architecture corresponding to the communication equipment is as follows Figure 16 shown.

[0192] It is not difficult to find that Figure 15 The communication equipment shown is in Figure 14 Based on the subtraction of wireless LAN module, according to different needs and application scenarios, it can be flexibly Figure 14 and Figure 15 The communication devices shown are selected to apply to the mobile terminal, and no further details are given here.

[0193] It is not difficult to find that this embodiment is a circuit embodiment corresponding to the method embodiment, and this embodiment can be implemented in conjunction with the method embodiment. The relevant technical details mentioned in the method embodiment are still valid in this embodiment, and to reduce repetition, they are not repeated here. Accordingly, the relevant technical details mentioned in this embodiment can also be applied to the method embodiment.

[0194] It is worth mentioning that all modules involved in this embodiment are logical modules. In actual applications, a logical unit can be a physical unit, a part of a physical unit, or a combination of multiple physical units.
