Description

Technical Field

[0001] The present invention relates to the field of communication technologies, and in particular to a Beidou RDSS wireless resource dynamic allocation method, system, and storage medium. Background Art

[0002] The BeiDou Navigation Satellite System is a global satellite navigation system developed independently by China. Short message communication is a unique feature of the BeiDou Navigation Satellite System. It enables two-way short message transmission between BeiDou ground terminals, BeiDou satellites, and the BeiDou ground monitoring station directly via satellite signals.

[0003] A SIM card assigned with a short message function requires the service support of the BeiDou-3 satellite's Radio Determination Satellite Service (RDSS) resources in order to carry out short message communications. Currently, RDSS wireless resource allocation uses a static resource configuration method to bind the user's service level to the SIM card in order to allocate RDSS wireless resources in advance. Due to the limited RDSS wireless resources, the number of SIM cards issued is limited, and once the RDSS wireless resources are allocated to the SIM card, it means long-term occupation, which makes it very easy for non-emergency users to occupy number segment resources, and emergency users to have no available number segment resources in emergency situations. Therefore, the current RDSS wireless resource allocation method is prone to problems such as tight RDSS wireless resources and poor flexibility. Summary of the Invention

[0004] In view of this, the purpose of the present invention is to provide a Beidou RDSS wireless resource dynamic allocation method, system and storage medium, which can improve the problems of RDSS wireless resource shortage and poor flexibility that are prone to occur in the current RDSS wireless resource allocation method.

[0005] In order to achieve the above objectives, the technical solutions adopted in the embodiments of the present invention are as follows.

[0006] In a first aspect, an embodiment of the present invention provides a BeiDou RDSS wireless resource dynamic allocation method, which adopts the following technical solution.

[0007] A Beidou RDSS wireless resource dynamic allocation method is applied to a service terminal of a Beidou RDSS wireless resource dynamic allocation system. The Beidou RDSS wireless resource dynamic allocation system further includes a plurality of terminal devices, each of which is pre-installed with an RDSS short message function in an inactivated state. The method includes:

[0008] Get the status switching request of the terminal device;

[0009] If the state switching request is to enter the emergency service, determining whether the current Beidou RDSS wireless resources meet the requirements of the terminal device;

[0010] If yes, switching the RDSS short message function of the terminal device to an activated state to enable the terminal device to implement short message communication;

[0011] If not, an RDSS resource busy instruction is sent to the terminal device, where the RDSS resource busy instruction is used to prompt the terminal device to resend the state switching request after a certain period of time.

[0012] Furthermore, the method further comprises:

[0017] Furthermore, the state switching request includes an identifier of the terminal device;

[0018] The step of switching the RDSS short message function of the terminal device to an activated state further includes:

[0019] querying the service level of the target device based on the identifier;

[0020] According to the service level, configuring a validity period adapted to the service level for the target device, and recording the validity period of the target device;

[0021] When the state switching request is for exiting the service, the step of obtaining the state switching request of the terminal device includes:

[0022] The service time of each terminal device in which the RDSS short message function is activated is counted. If the service time of a terminal device has reached the validity period of the terminal device, a state switching request for the terminal device is generated.

[0023] Furthermore, after the RDSS short message function of the terminal device is switched to an activated state, the method includes:

[0024] Enter the terminal device information whose RDSS short message function has been switched to the activated state into the valid device list.

[0025] Furthermore, after switching the RDSS short message function of the terminal device to an inactive state, the method further includes:

[0026] The terminal device information whose RDSS short message function has been switched to an inactivated state is deleted from the valid device list.

[0027] Furthermore, when the state switching request is to exit the service, the step of obtaining the state switching request of the terminal device includes:

[0028] Receive a state switching request sent by any terminal device.

[0029] In a second aspect, an embodiment of the present invention provides a BeiDou RDSS wireless resource dynamic allocation system, which adopts the following technical solution.

[0030] A BeiDou RDSS wireless resource dynamic allocation system includes a service terminal and multiple terminal devices, each of which is pre-installed with an RDSS short message function in an inactivated state;

[0031] The service terminal is configured to obtain a state switching request for a terminal device, and if the state switching request is for entering an emergency service, determine whether the current Beidou RDSS wireless resources meet the needs of the terminal device, and if so, send an activation instruction to the terminal device; if not, send an RDSS resource busy instruction to the terminal device;

[0032] The terminal device is used to switch its own RDSS short message function to an activated state in response to the activation instruction to realize short message communication, and is also used to respond to the RDSS resource busy instruction and re-send a state switching instruction to the service terminal after a certain time period.

[0033] Furthermore, the service terminal is further configured to send a release instruction to the terminal device if the state switching request is to exit the service;

[0049] The following will be combined with the accompanying drawings to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Generally, the components of the embodiments of the present invention described and shown in the drawings herein can be arranged and designed in various different configurations.

[0050] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the invention as claimed, but is merely intended to represent selected embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative work are within the scope of protection of the present invention.

[0051] It should be noted that relational terms such as "first" and "second" are used only to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations. Moreover, the terms "comprises," "comprising," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus comprising a series of elements includes not only those elements, but also other elements not explicitly listed, or elements inherent to such process, method, article, or apparatus. In the absence of further limitations, an element defined by the phrase "comprising a ..." does not exclude the presence of additional identical elements in the process, method, article, or apparatus comprising the element.

[0052] Satellite wireless communication resources are limited, especially the current BeiDou-3 satellite short message resources, which cannot meet the application requirements of all devices. This unmet user needs leads to high product prices and a small industry scale.

[0053] Analysis shows that the user scale in non-emergency scenarios reaches 1 billion, while the user scale in emergency scenarios is much smaller. However, the number of users that can be simultaneously served by the BeiDou-3 satellite's Radio Determination Satellite Service (RDSS) resources falls somewhere between these two scenarios.

[0054] A SIM card with short message functionality requires the support of the BeiDou-3 satellite's Radio Determination Satellite Service (RDSS) to carry out short message communications. Currently, RDSS radio resource allocation uses static resource configuration, binding the user's service level to the SIM card to pre-allocate RDSS radio resources.

[0055] Due to limited RDSS radio resources, the number of SIM cards issued is limited. Once RDSS resources are allocated to a SIM card, they are permanently occupied, making it easy for non-emergency users to occupy the number segment, leaving emergency users without it. Therefore, the current short message resource allocation method is prone to RDSS radio resource shortages and poor flexibility.

[0056] In view of this, an embodiment of the present invention provides a BeiDou RDSS wireless resource dynamic allocation solution, which can improve the problems of RDSS wireless resource shortage and poor flexibility existing in the current RDSS wireless resource allocation method. The solution will be described in detail below.

[0057] The BeiDou RDSS wireless resource dynamic allocation method provided by the embodiment of the present invention can be used for Figure 1 The illustrated Beidou RDSS wireless resource dynamic allocation system 100 includes a service terminal 110 and multiple terminal devices 120, each of which is pre-installed with an inactive RDSS short message function. Based on a state switching request received from a terminal device 120, the service terminal 110 switches the inactive RDSS short message function to an active state for each terminal device 120, if sufficient Beidou RDSS wireless resources are available, thereby implementing dynamic allocation of RDSS wireless resources.

[0058] When the RDSS short message function of terminal device 120 is not activated, terminal device 120 and service terminal 110 can communicate via the network. Furthermore, the Beidou RDSS wireless resource dynamic allocation system 100 may also include intermediate equipment and monitoring equipment at various disaster monitoring centers. Service terminal 110 may communicate with the intermediate equipment and monitoring equipment at various disaster monitoring centers via wired or wireless communication. Service terminal 110 may also communicate with terminal device 120 via satellite broadband or satellite radio.

[0059] When the RDSS short message function of the terminal device 120 is activated, the terminal device 120 and the service terminal 110 can communicate via short messages.

[0060] The communication methods mentioned above are merely examples and do not mean that the only communication methods mentioned above are included. In addition, the service terminal 110 can be a terminal such as a computer or a laptop, or can be implemented as an independent server or a server cluster consisting of multiple servers.

[0061] In one embodiment, Figure 2 As shown, a BeiDou RDSS wireless resource dynamic allocation method is provided. This embodiment mainly applies this method to Figure 1 Take the service terminal 110 in FIG. 1 as an example.

[0062] S101: Obtain a state switching request for a terminal device.

[0063] The state switching request may be a state switching request for multiple terminal devices 120 or a state switching request for one terminal device 120 .

[0064] S103: If the state switching request is to enter the emergency service, it is determined whether the current Beidou RDSS wireless resources meet the terminal equipment requirements. If so, step S105 is executed; otherwise, step S107 is executed.

[0065] If the state switching request is a state switching request for multiple terminal devices 120, it is determined whether the current Beidou RDSS wireless resources can meet the needs of all terminal devices 120. If not, the number of terminal devices 120 that can be met is determined.

[0066] If the state switching request is a state switching request of a terminal device 120, it is determined whether the RDSS wireless resources can satisfy a terminal device 120.

[0067] S105, switching the RDSS short message function of the terminal device to an activated state to enable the terminal device to implement short message communication.

[0068] S107: Send an RDSS resource busy instruction to the terminal device.

[0069] The RDSS resource busy instruction is used to prompt the terminal device 120 to resend the state switching request after a certain period of time.

[0070] When the state switching request is for multiple terminal devices 120 and the current Beidou RDSS wireless resources can accommodate a certain number of terminal devices 120, a certain number of terminal devices 120 can be randomly selected and switched to the active state, and an RDSS resource busy instruction is sent to the remaining unselected terminal devices 120. Activation can be performed in groups or one by one.

[0071] In the above-mentioned Beidou RDSS wireless resource dynamic allocation method, an RDSS short message function with switchable activation status is pre-installed on the terminal device 120, which can expand the scale of customer service. When the service terminal 110 receives a status switching request regarding the terminal device 120 for the need to enter emergency service, the short message function of the terminal device 120 is switched to an activated state or an RDSS resource busy instruction is returned based on whether the current Beidou RDSS wireless resources are sufficient. By implementing the dynamic allocation of RDSS wireless resources, the terminal device 120 will activate the RDSS short message function only when service is required, without having to occupy RDSS wireless resources all the time, thereby improving the problem of tight RDSS wireless resources and improving the flexibility of RDSS wireless resource allocation.

[0072] The terminal device 120 in the "state switching request for the terminal device 120" in step S101 is a terminal device 120 pre-installed with an inactivated RDSS short message function. However, after a period of use, the RDSS short message function of the terminal device 120 may be activated or inactivated.

[0073] It should be noted that, generally speaking, RDSS radio resources are vast, so sufficient BeiDou RDSS radio resources are available in most cases. However, when the number of terminal devices 120 simultaneously requiring short message communications reaches an upper limit, for example, on the order of one billion or more, there may be insufficient available RDSS radio resources. In such cases, step 107 is necessary.

[0074] For further information, please refer to Figure 3 The BeiDou RDSS wireless resource dynamic allocation method provided in an embodiment of the present invention further includes step S102, which is executed after step S101.

[0075] S102: If the state switching request is to exit the service, the RDSS short message function of the terminal device is switched to an inactive state to release the RDSS wireless resources occupied by the terminal device.

[0076] According to the state switching request, the terminal device 120 in the activated state may also be switched to the inactivated state, so that the terminal device 120 releases the RDSS wireless resources.

[0077] With respect to step S101 , the manner in which the service terminal 110 obtains the state switching request of the terminal device 120 can be flexibly selected.

[0078] When the state transition request requires access to emergency services, theoretically, the RDSS short message function of the "terminal device 120" in the "state transition request regarding the terminal device 120" is inactive. If the terminal device 120 itself can communicate with the service terminal 110 via the network or other communication methods, the state transition request can be sent by the terminal device 120 itself to the service terminal 110.

[0079] It should be understood that the state switching request may also be generated by the service terminal 110 itself, or may be sent to the service terminal 110 by an intermediate device or a monitoring device of a disaster monitoring center.

[0080] For example, when the administrator or the service terminal 110 monitors information about a natural disaster or emergency occurring in a certain place, the service terminal 110 itself generates a status switching request for the terminal device 120 in that place, or the administrator inputs a status switching request for the terminal device 120 in that place to the service terminal 110.

[0081] Alternatively, the user or relevant emergency personnel may send a state switching request to the service terminal 110 via a remote intermediate device. For example, it may be a satellite broadband communication or a radio satellite communication, or it may be relayed by an intermediate communication device.

[0082] Alternatively, when the monitoring equipment of the disaster monitoring center detects that a natural disaster or an emergency occurs in a certain place, the monitoring equipment sends a status switching request for the terminal device 120 in that place to the service terminal 110 .

[0083] When the state switching request is to exit the service, the state switching request can be sent by the terminal device 120 itself to the service terminal 110 via a communication method such as a short message. It should be understood that the RDSS short message function of the terminal device 120 is in an activated state at this time.

[0084] When the state switching request is for exiting the service, the state switching request may also be generated by the service terminal 110 itself. That is, the service terminal 110 obtains the state switching request of the terminal device 120 through the following steps: receiving a state switching request sent by any terminal device 120.

[0085] Each terminal device 120 has a corresponding validity period, that is, a terminal device 120 with the RDSS short message function activated has a validity period. The service terminal 110 records the validity period of each activated terminal device 120. When the service terminal 110 determines that the RDSS short message function of a terminal device 120 has been activated for a certain period of time and has reached the validity period, the service terminal 110 generates a state switching request for the terminal device 120.

[0086] In a possible implementation, the state switching request is a state switching request for at least one terminal device 120. However, it is not necessarily the case that the RDSS short message function of all terminal devices 120 related to the state switching request is in an inactive state. Figure 4 , which is a flowchart of some sub-steps of the above step S105, the RDSS short message function of the terminal device 120 can be switched to the activated state through the following steps.

[0087] S201 : Determine, among the terminal devices related to the state switching request, a terminal device whose RDSS short message function is not activated as a target device, and switch the RDSS short message function of the target device to an activated state.

[0088] In the case that the current Beidou RDSS wireless resources meet the needs of the terminal devices 120, the devices that are already in the activated state among the terminal devices 120 requesting state switching are ignored, and only the terminal devices 120 that are not in the activated state are activated.

[0089] The state switching request may include the identifier of the terminal device 120. Figure 4 , the above step S105 also includes the following sub-steps.

[0090] S202: Query the service level of the target device based on the identifier.

[0091] The server stores the service level of each terminal device 120 pre-installed with the RDSS short message function, and the service level can be stored in a dictionary relationship with the identification of the terminal device 120. By obtaining the identification of the target device, the corresponding service level can be queried.

[0092] S203: According to the service level, configure a validity period adapted to the service level for the target device, and record the validity period of the target device.

[0093] Different service levels have different validity periods. After the terminal device 120 is activated, the validity period and the identification are recorded in a dictionary relationship according to the identification of the terminal device 120 .

[0094] Thus, the service terminal 110 can count the service time of each terminal device 120 with the RDSS short message function activated. When the service time reaches the validity period of the terminal device 120, the service terminal 110 automatically generates a state switching request for the terminal device 120.

[0095] Furthermore, in order to facilitate the service terminal 110 to know which terminal devices 120 are in an active state. Figure 3 The BeiDou RDSS wireless resource dynamic allocation method provided by the present invention may further include the following step S106, which is executed after step S105.

[0096] S106, entering the terminal device information whose RDSS short message function has been switched to the activated state into the valid device list.

[0097] The terminal device 120 information includes but is not limited to the identification of the terminal device 120 , the validity period of the terminal device 120 , and the deployment area of ​​the terminal device 120 .

[0098] Therefore, it is possible to determine whether the terminal device 120 is located in a disaster area or an emergency area based on the deployment area of ​​the terminal device 120 .

[0099] For further information, please refer to Figure 3 The BeiDou RDSS wireless resource dynamic allocation method provided by the present invention further includes S108, which is executed after step S107.

[0100] S108, deleting the terminal device information whose RDSS short message function has been switched to an inactive state from the valid device list.

[0101] Through step S108, the valid device list is updated in time.

[0102] In a possible implementation, when the state switching request is a state switching request regarding multiple terminal devices 120, and the state switching request requires exiting the service, the above-mentioned step S107 can be implemented by the following steps: among the terminal devices 120 related to the state switching request, ignore the terminal devices 120 that are already inactive, and send an RDSS resource busy instruction to the remaining terminal devices 120.

[0103] It should be noted that when the state switching request is not sent by terminal device 120 to service terminal 110, service terminal 110 returns the RDSS resource busy instruction to the device that sent the state switching request. For example, if it is sent by an intermediate device, it is returned to the intermediate device; if it is sent by a monitoring device at a disaster monitoring center, it is returned to the monitoring device.

[0104] In one possible implementation, when the RDSS short message function of the terminal device 120 needs to be switched to an active state, the service terminal 110 can send an activation instruction to the terminal device 120. The terminal device 120 responds to the activation instruction and switches its own RDSS short message function to an active state. At this time, the service terminal 110 and the terminal device 120 can communicate via wired or wireless communication (excluding short message communication). Furthermore, this communication can be direct or indirect.

[0105] In indirect communication, the activation instruction can be sent to the terminal device 120 by a satellite via satellite broadband or satellite radio. This is suitable for situations where the service terminal 110 and the terminal device 120 are far apart. Alternatively, an intermediate device (such as an authorization terminal) can communicate with the terminal device 120 via wired or wireless means (such as Bluetooth). This is suitable for situations where the intermediate device and the terminal device 120 are close together.

[0106] Similarly, when the service terminal 110 sends the RDSS resource busy instruction, the above communication mechanism may also be adopted, and when sending the RDSS resource busy instruction, the service terminal 110 and the terminal device 120 may directly communicate via short messages.

[0107] The BeiDou RDSS wireless resource dynamic allocation method provided in this embodiment of the present invention implements dynamic allocation of RDSS wireless resources, scientifically manages and efficiently schedules the RDSS short message function of terminal device 120, and alleviates the problem of limited RDSS wireless resources. This method improves the resource allocation problem in the existing allocation method under the condition of "user scale in non-emergency scenarios >> user scale supported by BeiDou 3 RDSS resources > emergency user scale in emergency scenarios," allowing limited RDSS wireless resources to serve a larger user base. This method fully utilizes limited RDSS wireless resources and provides short message services to users in need as much as possible.

[0108] At the same time, it can promptly respond to the state switching request of the terminal device 120 and promptly switch the state of the RDSS short message function of the terminal device 120, thereby achieving more comprehensive coverage of short message functions and providing more cost-effective short message services.

[0109] Based on the BeiDou RDSS wireless resource dynamic allocation method provided in the above embodiment, in one embodiment, the present invention also provides the following Figure 1 The BeiDou RDSS wireless resource dynamic allocation system 100 shown in FIG. The BeiDou RDSS wireless resource dynamic allocation system 100 includes a service terminal 110 and a plurality of terminal devices 120 , each of which is pre-installed with an inactivated RDSS short message function.

[0110] It should be understood that the terminal device 120 is pre-installed with the RDSS short message function, and after use, the RDSS short message function of the terminal device 120 may be in an activated state or in an inactivated state.

[0111] The service terminal 110 is used to obtain a status switching request regarding the terminal device 120. If the status switching request is for entering emergency service, it determines whether the current Beidou RDSS wireless resources meet the needs of the terminal device 120. If so, an activation instruction is sent to the terminal device 120; if not, an RDSS resource busy instruction is sent to the terminal device 120.

[0112] The terminal device 120 is used to respond to the activation instruction, switch its own RDSS short message function to the activation state to realize short message communication, and is also used to respond to the RDSS resource busy instruction and re-send the state switching instruction to the service terminal 110 after a certain period of time.

[0113] In the above-mentioned Beidou RDSS wireless resource dynamic allocation system 100, when the service terminal 110 receives a status switching request regarding the terminal device 120 for entering emergency service, if the current Beidou RDSS wireless resources can meet the demand, the short message function of the terminal device 120 is switched to the activated state; otherwise, the RDSS resource busy instruction is returned to realize the dynamic allocation of RDSS wireless resources, so that the terminal device 120 will activate the RDSS short message function only when service is needed, without having to occupy RDSS wireless resources all the time, thereby improving the problem of tight RDSS wireless resources and improving the flexibility of RDSS wireless resource allocation.

[0114] Furthermore, the service terminal 110 is further configured to send a release instruction to the terminal device 120 if the state switching request is to exit the service.

[0115] The terminal device 120 is further configured to switch its own RDSS short message function to an inactive state in response to the release instruction, so as to release the occupied RDSS wireless resources.

[0116] In one embodiment, referring to Figure 5 The present invention also provides a Beidou RDSS wireless resource dynamic allocation device 130, which is applied to the service terminal 110 of the Beidou RDSS wireless resource dynamic allocation system 100. Its basic principles and technical effects are the same as those of the Beidou RDSS wireless resource dynamic allocation provided in the above-mentioned embodiments. For the sake of brevity, any details not mentioned in this embodiment are referred to the corresponding content in the above-mentioned embodiments. Beidou RDSS wireless resource dynamic allocation device 130 includes an acquisition module 140 and an activation module 150.

[0117] The acquisition module 140 is configured to acquire a state switching request of the terminal device 120 .

[0118] The activation module 150 is used to determine whether the current Beidou RDSS wireless resources meet the needs of the terminal device 120 if the state switching request is to enter the emergency service. If so, the RDSS short message function of the terminal device 120 is switched to the activated state to enable the terminal device 120 to realize short message communication. If not, an RDSS resource busy instruction is sent to the terminal device 120.

[0119] The RDSS resource busy instruction is used to prompt the terminal device 120 to resend the state switching request after a certain period of time.

[0120] Each module in the Beidou RDSS radio resource dynamic allocation device 130 can be implemented in whole or in part through software, hardware, or a combination thereof.
