Detailed Description
The following detailed description of embodiments of the invention refers to the accompanying drawings. It should be understood that the detailed description and specific examples, while indicating the present invention, are given by way of illustration and explanation only, not limitation.
In a Low Power Wide Area Network (LPWAN) system, a terminal is required to have extremely Low Power consumption due to Low rate and Low frequency of a service, and energy saving becomes an important requirement of the terminal. The Extended discontinuous reception mode (eDRX) is one of the methods for reducing energy consumption of a terminal, and the basic principle of the method is to require a terminal device to periodically enter a sleep mode, during the sleep mode, the terminal does not monitor a physical downlink control channel, and a transceiver unit is turned off to reduce energy consumption of the terminal device. Generally, an energy-saving method in the LPWAN affects the performance of a service in the aspect of time delay, and eDRX gives consideration to requirements in the aspects of power consumption and time delay compared with other energy-saving methods, and is suitable for services which have certain requirements on time delay while having low power consumption in services of the internet of things, such as a general remote operation scene.
The User Equipment (UE) comprises said Mobile Equipment (ME) and a Universal Integrated Circuit Card (UICC). The UICC is a Universal smart card platform that provides unified underlying support for its upper applications, and one of the core applications residing on it is the Universal Subscriber Identity Module (USIM). The USIM is a continuation and progress of a SIM card used in a Universal Mobile Telecommunications System (UMTS) network, and is used to store user identity information and personal data and guarantee security of access to a Mobile network service. The USIM can perform user identification and user authorization when a user accesses a mobile network service using necessary functions and data, and implement a requirement that the mobile network can express and identify a user application. In contrast to SIM cards, USIMs are no longer built on a single telecommunications application platform, but will become one of a variety of applications residing on universal integrated circuit cards. Besides USIM, other intelligent card applications such as bank and ticket can reside on the UICC, so that the separation of the bearing platform and the applications is really realized.
There is a developing procedure for the relationship between USIM and mobile device, where in the initial positioning the USIM is in a completely passive position, the mobile device sends commands to the USIM, the USIM executes the commands and returns responses to the mobile device, the mobile device and USIM interact with each other in a command or response pair, and both are the way the mobile device initiates the command USIM response, this mechanism does not allow the USIM to actively send commands to the mobile device, the mobile device is always dominant, and the USIM can only be in a controlled and controlled state that accepts commands, executes commands, and sends back responses from the mobile device, thus limiting the development and use of USIM based applications.
With the development of USIM service requirements, in order to solve such problems, an STK/USAT protocol layer is introduced into a protocol stack of a Cu interface (an interface of a mobile device and a USIM), and the STK/USAT layer provides a service mechanism based on a service provided by a transport layer, so that a USIM application is allowed to interact and operate with a mobile device supporting the service mechanism, so that the USIM can actively request the mobile device to perform a certain operation, and an STK/USAT instruction set is a basis and a main mode for a telecommunication smart card to implement services through a terminal. Various applications may also be implemented on the USIM and provided to the user via the mobile device via the STK/USAT protocol.
In eDRX, when a mobile device in a user terminal is about to enter an extended discontinuous reception mode, there is also a corresponding process on the USIM, which requests the USIM to switch from an active and normally operating state to a suspended state. The USIM may also provide a corresponding suspend function to support implementation of eDRX, for example, after the USIM may receive a suspend command sent by the mobile device, suspend the original active state and the existing session, and store the existing state. After the USIM resumes from the suspend pending state, the stored state may be restored to a new session.
However, the current actual service process often faces a complicated situation, and the USIM directly executes the suspend command, which may cause normal service interruption, affect the USIM running state, and result in poor user experience.
In order to solve the foregoing problems, embodiments of the present invention provide a USIM management method, which is applied to a USIM included in a User Equipment (UE). The user terminal includes a Mobile Equipment (ME) and a USIM.
Fig. 1 is a USIM management method according to an embodiment of the present invention. As shown in fig. 1, the method comprises the steps of:
step S101, receiving a USIM management command sent by the mobile equipment in the eDRX mode.
The eDRX mode (Extended DRX) is a power saving mode of the ue.
In one embodiment, in case that the mobile device generates a need to enter the extended discontinuous reception mode, the mobile device generates and transmits a USIM management command to the USIM, for the USIM to perform the above step S101. Wherein the USIM management command is a control command that the mobile device extends to support eDRX mode for the USIM according to a USAT (USIM Application Toolkit) mechanism, instead of a suspend command that the current mobile device sends to the USIM. The USIM management command includes information such as a suspend USIM control flag, an equipment identifier, and a USIM status management type.
In one embodiment, the USIM on the USIM receives a USIM management command with the mobile device named "Suspend USIM Control by USIM". The structure of the USIM management command is as follows:
Figure BDA0003066504860000071
Figure BDA0003066504860000081
the USIM status management type is an extended data object, and represents a status management type of the USIM required by the USIM management command, and currently includes suspension of USIM management or resumption of USIM management. M represents optional, O represents optional, MIN represents whether minimum length exists, length represents the length of the field when the corresponding field takes the minimum length, and Y represents yes.
In one embodiment, the USIM management command contains a preset field. After receiving the USIM management command sent by the mobile device, the USIM on the USIM further comprises: recognizing that a preset character bit in a preset field is a first preset value or a second preset value, if the preset character bit is recognized as the first preset value, recognizing that a state management type contained in the USIM management command is a USIM pause type, and executing the following step S102; and if the USIM management command is identified as the second preset value, identifying the state management type contained in the USIM management command as the type of recovering the USIM. The preset field may be a field where a USIM status management type is located, where the first preset value is 1, and the second preset value is 2.
In one embodiment, if the state management type included in the USIM management command is recognized as the type of the USIM to be restored, the USIM restores the USIM from the suspend suspended state to the original active state, and restores the stored state of the existing session to a new session.
Step S102, under the condition that the state management type contained in the USIM management command is the type of the suspended USIM, judging whether to allow the operation of suspending the USIM to be immediately executed or not according to the current service state of the application carried by the USIM management command, and generating a first judgment result.
In one embodiment, the USIM determines whether to allow an operation of suspending the USIM to be immediately performed based on the current service state of the application carried by the USIM, and the step of generating the first determination result includes: and under the condition that the current states of the applications borne by the USIM are idle states, judging that the operation of suspending the USIM is allowed to be immediately executed, and generating a first judgment result, wherein the first judgment result is a result of allowing the operation of suspending the USIM to be immediately executed.
In another embodiment, an application hosted by the USIM is currently in a service processing procedure, for example, in a case that an application of the internet of things hosted by the USIM is in an interaction procedure with a service platform, or the application hosted by the USIM is in a network connection state, it is determined that an operation of suspending the USIM is not allowed to be immediately performed, and a first determination result is generated, where the first determination result is that the operation of suspending the USIM is not allowed to be immediately performed.
In yet another embodiment, the application hosted by the USIM is currently in an automatic configuration process, for example, in a case where the application hosted by the USIM is about to or has been subjected to remote download, upgrade, or the like, it is determined that the operation of suspending the USIM is not allowed to be immediately performed, and a first determination result is generated, where the first determination result is that the operation of suspending the USIM is not allowed to be immediately performed.
Step S103, in case that the first determination result is that the operation of suspending the USIM is allowed to be immediately performed, transmitting a first response message to the mobile device and immediately performing the operation of suspending the USIM.
In one embodiment, in a case where the first determination result is that the operation of suspending the USIM is allowed to be immediately performed, the USIM generates a first response message based on the first determination result, and then performs the above-described steps of transmitting the first response message to the mobile device and immediately performing the operation of suspending the USIM. Wherein the first response message includes a first judgment result that allows the operation of suspending the USIM to be immediately performed.
In one embodiment, the structure of the first response message is as follows:
Figure BDA0003066504860000091
wherein, the content of the information field of the control result is 00, which indicates that the USIM allows the operation of suspending the USIM to be executed immediately.
In one embodiment, the USIM performs an operation of suspending the USIM, causes the USIM to enter an extended discontinuous reception mode even if the USIM suspends an original activation state and an existing session, and stores the state of the existing session. In the embodiment provided by the invention, the USIM management command replaces a suspend suspension command sent by the current mobile equipment to the USIM, the interactive relation between the mobile equipment and the USIM is improved, after the USIM receives the USIM management command, the USIM judges whether to allow the operation of suspending the USIM to be immediately executed or not based on the current service state of the application born by the USIM, and the USIM is suspended only under the condition that the operation of suspending the USIM can be immediately executed, so that the problem that the service is easy to interrupt when the USIM supports eDRX in the current service scene is solved, the rationality and feasibility of the service of the eDRX can be improved, the initiative and flexibility of the USIM included by the USIM in the eDRX service aspect are enhanced, the support of the eDRX by the USIM is realized with high quality, and the requirements of the user terminal on service realization and energy conservation and consumption reduction are simultaneously considered.
In another embodiment, after the USIM performs the operation of suspending the USIM, when suspension is performed for a certain time, the mobile device temporarily ends dormancy to a paging window to enter an eDRX cycle, and a need to resume the USIM is generated and transmitted to the USIM by the mobile device in response to the eDRX mode being suspended. The USIM receives a USIM management command sent by the mobile equipment in response to the suspension of the eDRX mode, performs an operation of recovering the USIM under the condition that a state management type contained in the USIM management command is a type of recovering the USIM, and sends a third response message to the mobile equipment. Specifically, the USIM performs an operation of recovering the USIM including: and restoring the USIM from the suspended state to the original activated state, and restoring the stored state of the existing session to the new session. The structure of the third response message is as follows:
Figure BDA0003066504860000101
and step S104, in the case that the first judgment result is that the operation of suspending the USIM is not allowed to be immediately executed, sending a second response message to the mobile equipment.
In one embodiment, in a case where the first determination result is that the operation of suspending the USIM is not allowed to be immediately performed, the USIM generates a second response message and performs the step of transmitting the second response message to the mobile device. Wherein the second response message includes a first determination result that the operation of suspending the USIM is not allowed to be immediately performed.
It should be noted that the response messages (including the first response message, the second response message, and the third response message) are all used for the mobile device to know whether the USIM performs an operation of suspending the USIM, and further know whether the USIM enters the extended discontinuous reception mode.
In one embodiment, as shown in fig. 2, in order to enable the user terminal to simultaneously meet the requirements of both service implementation and energy saving and consumption reduction, the step of generating, by the USIM, the second response message includes the following steps:
step S201, determining whether the state duration can be calculated based on the current service state of the application carried by the user, and generating a second determination result.
In one embodiment, the USIM determines whether to preset an evaluation procedure capable of calculating the state duration based on the current service state of the application carried by the USIM, and generates the second determination result that the state duration cannot be calculated based on the current service state of the application carried by the USIM without presetting the evaluation procedure. Under the condition of presetting the evaluation program, the generated second judgment result is that the state duration can be calculated based on the current service state of the application carried by the second judgment result. It should be noted that the preset evaluation program may be a time prediction program, or may be dynamically set according to a specific implementation scenario, which is not limited herein.
Step S202, under the condition that the second judgment result is that the state duration can not be calculated based on the current service state of the application carried by the second judgment result, a second response message is generated based on the first judgment result.
The second response message includes the first judgment result, and the first judgment result is that the operation of suspending the USIM is not allowed to be executed immediately.
In one embodiment, the structure of the second response message is as follows:
Figure BDA0003066504860000111
wherein, the content in the information field of the control result is 01, which indicates that the USIM is not allowed to immediately execute the operation of suspending the USIM.
Step S203, when the second determination result is that the state duration can be calculated based on the current service state of the application carried by the second determination result, obtaining the state duration, and generating a second response message based on the first determination result and the state duration.
The second response message comprises a first judgment result and a state duration, wherein the first judgment result is that the operation of suspending the USIM is not allowed to be immediately executed.
In one embodiment, an evaluation procedure is preset on the USIM, and the step of obtaining the estimated duration by the USIM comprises: an evaluation program on the USIM calculates the state duration based on the various state parameters of the current traffic state of the application hosted by the USIM. The status parameters include, for example, update progress, download progress, total data transmission amount, data transmission rate, and the like.
In one embodiment, in the step of generating, by the USIM, a second response message based on the first determination result and the state duration, the second response message has the following structure:
Figure BDA0003066504860000121
wherein, the content of the information field of the control result is 01, which indicates that the USIM is not allowed to immediately execute the operation of suspending the USIM. The duration is an optional data object in the response message, that is, the "M/O/C" information field is "O", and the duration information field may exist in the response message only when the content of the control result in the information field is 01. M represents optional, O represents optional, and C is a condition. MIN indicates whether there is a minimum length, Length indicates the length of the field when the corresponding field takes the minimum length, Y indicates Yes, and N indicates No.
In one embodiment, the USIM obtains the state duration when the second determination result is that the state duration can be calculated based on the current service state of the application carried by the USIM, and generates a second response message based on the first determination result and the state duration, where the second response message includes the state duration. The USIM transmits the second response message to the mobile device, which receives the second response message and may transmit a USIM management command to the USIM again after the duration of the state elapses,
in one embodiment, after sending a second response message to the mobile device when the first determination result is that the operation of suspending the USIM is not allowed to be performed immediately and the second determination result is that the state duration can be calculated based on the current service state of the application carried by the second response message, the method further includes: after the status duration elapses, the USIM receives the USIM management command transmitted by the mobile device (the USIM performs the above step S101).
