[0027] In order to enable ordinary persons in the art to better understand the technical solutions of the present disclosure, the technical solutions in the exemplary embodiments of the present disclosure will be clearly and completely described below with reference to the accompanying drawings.

[0028] The terms used herein are for the purpose of describing specific example embodiments and are not intended to be limiting. As used herein, unless the context clearly indicates otherwise, the singular forms "a", "an", "said", and "the" are also intended to include the plural forms. In addition, when the terms "comprise", "include", and / or their variations are used in this specification, the existence of the stated features, wholes, steps, operations, elements, components, and / or their groups is indicated, but the existence or addition of one or more other features, wholes, steps, operations, elements, components, and / or their groups is not excluded. The example embodiments described in the following description do not represent all implementations consistent with the present disclosure. Instead, they are merely examples of devices and methods consistent with the present disclosure as detailed in the claims.

[0029] It should be noted that the phrase "at least one of the several items" in this disclosure includes three types of parallel situations: "any one of the several items", "a combination of any multiple of the several items", and "all of the several items". For example, "including at least one of A and B" includes the following three parallel situations: (1) including A; (2) including B; (3) including A and B. For another example, "performing at least one of step 1 and step 2" means the following three parallel situations: (1) performing step 1; (2) performing step 2; and (3) performing both step 1 and step 2.

[0030] According to some example embodiments of the present disclosure, the terminal described below may include at least one of a smart phone, a tablet personal computer (PC), a mobile phone, a video phone, an e-book reader, a desktop PC, a laptop computer, a netbook computer, a workstation, a server, a personal digital assistant (PDA), a portable multimedia player (PMP), an MP3 player, a mobile medical device, a camera, or a wearable device (such as a smart watch, a smart bracelet, etc.), but is not limited thereto.

[0031] The following will be combined Figures 1 to 5 to describe some example embodiments according to the present disclosure.

[0032] Figure 1 Examples of application scenarios according to some example embodiments of the present disclosure are shown.

[0033] In related technologies, D2D public safety direct connectivity services are primarily categorized into two types: Proximity-based Service (ProSe) discovery and ProSe communication. ProSe discovery includes the following eight types: Restricted Model A Monitoring, Restricted Model A Announcing, Restricted Model B Discoverer, Restricted Model B Discoveree, Model A Monitoring, Model A Announcing, Model B Discoverer, and Model B Discoveree. ProSe communication includes both multicast and unicast communication.

[0034] Some example embodiments of the present disclosure can be applied to service authorization scenarios between a D2D terminal and a D2D server. According to some example embodiments of the present disclosure, in a D2D service authorization scenario, three modules are involved: a ProSe network server (ProSe Function), a User Equipment (UE) PC3 Link Manager (PC3 Link Manager of UE), and a UE ProSe Service Manager (ProSe Service Manager of UE). The ProSe Function is used to send an authorization response message to the terminal. The UE PC3 Link Manager is used to establish an HTTP link and perform signaling exchanges between the terminal and the ProSe network server. The UE ProSe Service Manager is used to control the processing of the terminal's authorization request, for example, maintaining and managing timers related to authorization durations. Specifically, when a terminal activates ProSe discovery and ProSe communication services, it checks service authorization information, all of which is stored in the ProSe network server. When a terminal activates a service, it sends an MO request message to the ProSe network server. After receiving the MO request message, the ProSe network server sends an MO response message to the terminal. The MO response message includes multiple authorization durations for multiple authorized services. For example, based on the different service scenarios supported by D2D, the ProSe network server sends the terminal 10 authorization durations corresponding to authorized services for ProSe discovery and ProSe communication. Therefore, authorized services can be services that require authorization to complete or participate in. For each authorized service, a corresponding T4005 timer is used to set the authorization duration. When the authorization time for a particular authorized service exceeds the corresponding authorization duration (for example, when the corresponding T4005 timer expires), the terminal stops providing that service. At this point, the terminal can apply for a new authorization duration to resume providing the service.

[0035] In related technologies, for multiple authorized services, a terminal needs to make multiple authorization requests based on multiple authorization durations to obtain multiple new authorization durations. For example, for 10 authorized services, the terminal needs to apply for a new authorization duration each time the T4005 timer expires. This frequent authorization request operation increases the number of interactions between the terminal and the ProSe network server, which may affect the corresponding service quality. For example, when the D2D service is busy, it may affect the D2D service quality on the direct communication interface PC5.

[0036] In addition, since the range of values ​​of different authorization durations for different authorization services is large, for example, the authorization duration of the T4005 timer may range from 1 minute to 505600 minutes, it is necessary to set multiple timers with large differences for different authorization durations, which increases the complexity of the timer. It is necessary to use appropriate algorithms to simplify the timer settings to simplify the terminal implementation and improve the availability of the terminal software.

[0037] It should be understood that the above application scenarios are only examples, and the exemplary embodiments according to the present disclosure are not limited to the above application scenarios.

[0038] Figure 2 A flowchart illustrating a method for applying for authorization duration according to some example embodiments of the present disclosure is shown. Figure 3 A diagram showing the signaling interaction of the method for applying for authorization duration according to some example embodiments of the present disclosure. Figure 3 right Figure 2 The steps in the method of applying for authorization time are described in detail.

[0039] Reference Figure 2 In step S201, when service authorizations for multiple authorized services are received, multiple authorization durations for the multiple authorized services are obtained. Optionally, multiple authorization service timers corresponding to the multiple authorized services are started simultaneously with the multiple authorization durations for the multiple authorized services.

[0040] Reference Figure 3 In the aforementioned D2D service authorization scenario, when a terminal needs to enable multiple D2D authorized services, in step S301, the UE PC3 link manager sends an MO request message to the ProSe network server. In step S302, in response to receiving the MO request message, the ProSe network server sends an MO response message to the UE PC3 link manager. The MO response message includes multiple authorization durations corresponding to the multiple authorized services and other information related to the authorized services. In step S303, the UE PC3 link manager notifies the UE ProSe service manager of the authorization duration information. The UE (using a semiconductor chip, processor, transceiver, and / or other hardware components) can perform operations based on, or included in, the authorized services, such as audio calls, video calls, file transfers, or other D2D services. These operations can be performed during and based on the authorized duration.

[0041] Return to reference Figure 2In step S202, based on the minimum authorization duration (optionally, the lowest authorization duration, or the lower authorization duration) among the multiple authorization durations and the timer duration set by the user for applying for authorization in advance, the periodic timer duration for obtaining multiple authorization services at one time is determined.

[0042] That is, when there are multiple authorization durations, in addition to determining the duration of the timer for each authorized service, the periodic timer duration of a newly added periodic timer will also be set based on the minimum authorization duration among the multiple authorization durations and the duration of the timer set by the user for pre-application authorization. The newly added periodic timer is used to time the durations of multiple new authorization durations applied for multiple authorized services at one time. To avoid risks that may arise when a terminal applies for a new authorization duration in response to the expiration of the timer with the minimum authorization duration (for example, when the timer with the minimum authorization duration expires, the terminal may fail to successfully apply for a new authorization duration, resulting in service interruption, or the terminal may be unable to obtain a new authorization duration in a poor network environment), a periodic timer duration that is smaller than the minimum authorization duration may be determined to ensure the continuous availability of services provided by the terminal.

[0043] Here, the timer duration set by the user for applying for authorization in advance can be set arbitrarily by the user, for example, the timer duration for applying for authorization in advance is input by the user, the timer duration for applying for authorization in advance can be pre-set by the user or programmed in other ways, or the timer duration for applying for authorization in advance can be determined according to various other appropriate methods.

[0044] Like this, using the periodic timer set based on the periodic timer duration smaller than the minimum authorization duration, the terminal can be notified in time that a new authorization duration needs to be applied before all authorization duration timers expire or before all authorized services expire.

[0045] Optionally, the step of determining the periodic timer duration for obtaining multiple authorized services at one time based on the minimum authorization duration among the multiple authorization durations and the timer duration set by the user for applying for authorization in advance includes: when the minimum authorization duration is greater than the timer duration set by the user for applying for authorization in advance, setting the periodic timer duration to the timer duration set by the user for applying for authorization in advance; and when the minimum authorization duration is less than or equal to the timer duration set by the user for applying for authorization in advance, setting the periodic timer duration to a duration that is smaller than the minimum authorization duration and is determined based on a preset or expected time advancement parameter. Optionally, the duration that is smaller than the minimum authorization duration and is determined based on a preset or expected time advancement parameter is a duration obtained by multiplying the preset or expected time advancement parameter by the minimum authorization duration, wherein the preset or expected time advancement parameter is a percentage greater than 0 and less than 1.

[0046] The following takes the periodic timer duration F(X) as an example to explain in detail the determination of the periodic timer duration. Assume that the preset value or expected value (i.e., the timer duration set by the user for applying for authorization in advance) is X (in days), the periodic timer duration F(X) of the periodic timer is in milliseconds (ms), the minimum authorization duration is A (in minutes (min)), and the preset or expected time advancement parameter is , where K is an integer from 1 to 99, the timing duration F(X) can be determined by equation (1):

[0047]

[0048] According to the above equation (1), when the minimum authorization duration is greater than the timer duration set by the user for applying for authorization in advance, the timer duration X set by the user for applying for authorization in advance is set as the timer duration, and when the minimum authorization duration is less than or equal to the timer duration set by the user for applying for authorization in advance, the result of multiplying the minimum authorization duration by a percentage greater than 0 and less than 1 is used as the periodic timer duration. In this way, a new authorization duration can be applied in advance before the authorized service with the minimum authorization duration expires, thereby avoiding service interruption.

[0049] In step S203, a periodic timer set based on the periodic timer duration is started. Figure 3In step S304, the UE ProSe service manager starts multiple timers for multiple authorization services based on multiple authorization durations to time the multiple authorization services. In step S305, the UE ProSe service manager starts a periodic timer based on the periodic timer duration determined in the above embodiment to time the authorization request. Here, step S304 and step S305 can be performed simultaneously.

[0050] At the same time, in step S309, when the service is triggered (in other words, when a service request is received), the UE ProSe service manager verifies whether the service is within the authorized duration. Specifically, when verifying whether the service is within the authorized duration in step S309, the timer corresponding to the service started in step S304 is used to determine whether the service is within the authorized duration. In other words, step S304 is primarily used to verify whether the service is authorized in step S309. If the timer corresponding to the service is started in step S304, the service is deemed authorized in step S309, and the terminal can provide the service or the user can use the service.

[0051] Therefore, according to some example embodiments of the present disclosure, the method for applying for authorization duration also includes: while obtaining the multiple authorization durations, starting timers corresponding to the multiple authorization services that are set based on the multiple authorization durations respectively, and when receiving a service request for one or more services, using one or more timers corresponding to the one or more services to verify whether the one or more services are within the corresponding authorization duration.

[0052] Return to reference Figure 2 In step S204, in response to the expiration of the periodic timer, a plurality of new authorization durations for the plurality of authorization services are applied for. Figure 3 In step S306, when the timer for the authorization application times out, the UE ProSe service manager notifies the UE PC3 link manager that the timer has expired.

[0053] In order to prevent the periodic timer from being too long, the number of times the periodic timer times out can be counted. When the periodic timer times out and the number of times the periodic timer times out meets a predetermined or expected condition, multiple new authorization durations for the multiple authorization services are applied for. Optionally, in response to the periodic timer timing out, the step of applying for multiple new authorization durations for the multiple authorization services includes: setting a count value for the periodic timer based on the minimum authorization duration and the timer duration set by the user for applying for authorization in advance, determining whether the periodic timer has timed out, determining whether the count value is equal to 1 in response to the periodic timer timing out, and when the count value is equal to 1, applying for multiple new authorization durations for the multiple authorization services; when the count value is not equal to 1, reducing the count value by 1, restarting the periodic timer, and performing the judgment.

[0054] Refer to the following Figure 4 This is described in detail. Figure 4 FIG. 1 is a flowchart illustrating the authorization application processing of a periodic timer according to an embodiment of the present disclosure. Figure 2 After step S203, in step S401, a count value Y of a periodic timer based on the periodic timer duration setting may be set. Here, the count value Y may be an integer greater than or equal to 1.

[0055] In step S402, it is determined whether the periodic timer has timed out.

[0056] When the cycle timer times out, in step S403, it is determined whether the count value Y is equal to 1. When the cycle timer has not timed out, the timing of the cycle timer is continued.

[0057] When the periodic timer times out and the count value Y is equal to 1, in step S404, a plurality of new authorization durations for the plurality of authorized services are applied for.

[0058] When the periodic timer times out and the count value Y is not equal to 1 (i.e., the count value Y is greater than 1), in step S405, the count value Y is decremented by 1, and in step S406, the periodic timer is restarted. Accordingly, the determination of whether the periodic timer has timed out is re-executed, that is, the above steps S402 to S406 are repeated. Here, steps S405 and S406 can be executed simultaneously, or step S406 can be executed before step S405.

[0059] Optionally, the step of setting the count value for the periodic timer based on the minimum authorization duration and the timer duration set by the user for applying for authorization in advance includes: when the minimum authorization duration is greater than the timer duration set by the user for applying for authorization in advance, determining the intermediate quantity by dividing the minimum authorization duration by the timer duration set by the user for applying for authorization in advance; if the intermediate quantity is an integer, setting the count value to the value of the intermediate quantity minus 1; otherwise, setting the count value to the value of the intermediate quantity rounded down; when the minimum authorization duration is less than or equal to the timer duration set by the user for applying for authorization in advance, setting the count value to 1.

[0060] The following uses the example of determining the duration of the above-mentioned periodic timer as an example to explain in detail the determination of the count value. Assuming that the preset value or expected value (i.e., the timer duration set by the user for applying for authorization in advance) is X (in days), the minimum authorization duration is A (in minutes (min)), and the intermediate quantity is Z, the timing duration F(X) can be determined by equations (2) and (3):

[0061]

[0062] According to equations (2) and (3), when the timer duration set by the user for applying for authorization in advance is less than the minimum authorization duration, if the minimum authorization duration is divisible by the timer duration set by the user for applying for authorization in advance, the value of the result minus 1 is set as the count value of the periodic timer. In this way, it is ensured that the periodic timer will time out a period of time X in advance before the authorization service with the minimum authorization duration expires, and a new authorization duration is applied in advance. When the timer duration set by the user for applying for authorization in advance is less than the minimum authorization duration, if the minimum authorization duration is not divisible by the timer duration set by the user for applying for authorization in advance, the value of the result rounded down is set as the count value of the periodic timer. In this way, it is ensured that the periodic timer will time out at least a period of time in advance before the authorization service with the minimum authorization duration expires, and a new authorization duration is applied in advance. When the timer duration set by the user for applying for authorization in advance is greater than or equal to the minimum authorization duration, the periodic timer is only executed once. When the periodic timer set based on the periodic timer duration smaller than the minimum authorization duration times out, a new authorization duration is applied in advance.

[0063] Like this, by setting the periodic timer length to be smaller than the minimum authorization length and by setting the number of periodic timer timings, this design mechanism can ensure that the terminal applies for a new authorization length in advance before any authorized service expires, avoiding service interruption and improving the interaction efficiency between the terminal and the server, thereby ensuring service quality.

[0064] Return to reference Figure 3 In step S307, the UE PC3 link manager sends an MO request message to the ProSe network server to apply for a new authorization duration. In step S308, the ProSe network server sends an MO response message including multiple new authorization durations for multiple authorized services to the UE PC3 link manager.

[0065] In addition, Figure 3 In the example, the UE ProSe service manager also always verifies the authorization service during the period when the terminal provides the authorization service.

[0066] Determining the authorization request timer duration based on the minimum or lowest authorization duration among multiple authorization durations can avoid or reduce frequent interaction interruptions caused by multiple authorization requests, effectively reducing network data pressure. Furthermore, by setting the periodic timer duration and count value of the periodic timer, terminal timer implementation can be simplified and continuous service availability can be ensured.

[0067] Furthermore, in related technologies, if a terminal is in an out-of-coverage (OOC) state when a periodic timer expires, the terminal cannot obtain a new authorization duration from the server, effectively rendering the terminal unable to continue providing services. If this fails, the terminal will return a warning or error message and interrupt the corresponding service. This can cause service failures due to authorization failure, reducing terminal availability.

[0068] In some example embodiments of the present disclosure, optionally, when a terminal that has received service authorization for the multiple authorized services switches from the in-coverage IC state to the out-of-coverage OOC state, the timing of the multiple authorization durations for the multiple authorized services and the timing of the periodic timer are suspended; when the terminal switches from the OOC state to the IC state, the timing of the multiple authorization durations for the multiple authorized services and the timing of the periodic timer are resumed. That is, when the terminal is in the OOC state where it cannot apply for or receive a new authorization duration, all timers related to the authorized service are turned off to suspend timing, and when the terminal re-enters the IC state, all timers related to the authorized service are turned on to resume timing. In this way, when authorization cannot be obtained due to reasons such as network instability of the terminal, the timing of the timer is stopped, thereby avoiding or reducing the problem that the terminal is still unable to apply for or receive a new authorization duration when the authorized service expires and the service is interrupted by the harsh network environment.

[0069] Figure 5 A structural block diagram of a terminal for applying for authorization duration according to some example embodiments of the present disclosure is shown.

[0070] Reference Figure 5 According to some example embodiments of the present disclosure, a terminal 500 for applying for an authorization duration includes: an authorization acquisition unit 501, a duration determination unit 502, a timer unit 503, and an authorization application unit 504.
