Detailed Description
The following describes specific embodiments of the present invention in detail with reference to the drawings. It should be understood that the detailed description and specific examples, while indicating and illustrating the invention, are not intended to limit the invention.
The universal subscriber identity module (Universal Subscriber Identity Module, USIM) is a continuation and advancement of the SIM cards used in UMTS networks. In contrast to a SIM card, a USIM card is no longer built on a single telecommunications application platform, but will become one of many applications residing on a universal integrated circuit card (Universal Integrated Circuit Card, UICC).
The current User Equipment (UE) is generally composed of a UICC and a Mobile Equipment (ME). There is a evolving process of the relationship between UICC and mobile device in which, in the initial mechanism, UICC is not allowed to actively send commands to mobile device, which limits the development and use of applications residing on UICC.
With the development of UICC business requirements, USAT (USIM Application Toolkit ) technology was introduced in order to solve such problems. The implementation mechanism is to introduce STK/USAT protocol layer in the protocol stack of the interface of the mobile device and UICC. The STK/USAT layer provides a service mechanism on the basis of the services provided by the transport layer, allowing applications residing on the UICC, such as USIM, to interact and operate with mobile devices supporting such mechanisms.
The bearer independent protocol (Bearer Independent Protocol, BIP) is a basic protocol for realizing remote data downloading and management by the UICC through CAT/TP, HTTPS and the like at present, and is one of main capabilities realized by the UICC through an STK/USAT mechanism. The UICC can establish a BIP channel through the mobile equipment, the mobile equipment selects an available data bearer according to the information provided by the UICC when the BIP channel is established, and allows the UICC and the remote server to exchange data on the channel through the available data bearer, so that the download, update and management of the remote application, the file and other contents of the UICC are realized. In the process of transmitting data through the BIP channel, the UICC needs to maintain the state of the BIP channel.
The current UICC maintains the BIP path first to obtain the status of the BIP path from the mobile device. However, with the continuous development of remote data transmission services, the data transmission volume is increasing, and the management requirement for BIP channels is increasing. For example, in a transmission scenario with a large data volume, the UICC needs to actively initiate interactions with the mobile device multiple times to obtain the status of the BIP channel, which results in complicated flow, low efficiency and large resource consumption of the BIP channel maintenance.
In order to solve the above-mentioned problems, the embodiment of the present invention provides a BIP channel state management method applied to a mobile device of a user terminal, where the user terminal includes a mobile device and a UICC.
Fig. 1 is a flowchart of a BIP channel state management method according to an embodiment of the present invention, as shown in fig. 1, the method includes the following steps:
step S101, a first channel state management command sent by the UICC is received.
The first channel state management command includes an operation identifier for starting to periodically provide channel states.
In one embodiment, when the UICC needs to perform remote data transmission, a BIP channel is established through the mobile device, the mobile device selects an available data bearer when the BIP channel is established, and allows the UICC and the remote server to perform data transmission on the BIP channel through the available data bearer connection, so as to realize downloading, updating and management of remote applications, files and other contents of the UICC. And under the condition that the UICC generates a requirement for requiring the mobile equipment to provide the channel state of the BIP channel according to the service requirement, generating a first channel state management command and sending the first channel state management command to the mobile equipment. The mobile device performs the above-described step S101, and in the case that the operation identifier for starting the periodically provided channel state is included in the first channel state management command, performs the following step S102.
Step S102, a channel state response message is sent to the UICC in response to the first channel state management command.
Wherein the channel state response message contains the current BIP channel state of the BIP channel. The BIP channel state includes any one or more of state information of a connection setup state, an activation state, whether there is an abnormality, and the like.
Step S103, after sending the channel state response message to the UICC, sending a channel state event downloading command to the UICC every a predetermined state providing period.
The channel state event download command includes a BIP channel state acquired in a current state providing period.
The BIP channel state management method provided by the embodiment of the invention comprises the steps of firstly, receiving a first channel state management command sent by a UICC, then responding to the first channel state management command, and sending a channel state response message to the UICC based on a predetermined state providing period, wherein the channel state response message comprises the current BIP channel state of a BIP channel, and after sending the channel state response message to the UICC; and sending a channel state event downloading command to the UICC every a predetermined state providing period, wherein the channel state event downloading command comprises the BIP channel state acquired in the current state providing period, so that the mobile device can periodically and actively provide the BIP channel state only through one interaction initiated by the UICC, the BIP channel state management flow is simplified, the capability of the mobile device and the UICC for maintaining the BIP channel state is enhanced, the BIP channel maintenance efficiency is improved, and the resource consumption of the mobile device and the UICC is reduced. In addition, because the BIP channel is a transmission channel established by the UICC through the mobile equipment according to service requirements, the BIP channel state management flow is simplified, the maintenance efficiency of the BIP channel is improved, the realizability of the service requirements is enhanced, and an implementation scheme is provided for enriching service scenes and supporting service evolution.

wherein M represents optional, O represents optional, and C is optional. 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 the command qualifier, b1 is an operation identifier for providing a channel state, and in the first channel state management command, b1 may be a first preset value or a second preset value, for example, the first preset value is 0, and the second preset value is 1. b1 is 1, the first channel state management command includes an operation identifier for starting the periodic channel state provision; b1 is 0, indicating that the first channel state management command includes an operation flag to close the periodically provided channel state.
In some embodiments, the first channel state management command further includes a first period and a period modification function identification preset by the UICC. The first period is a conditional mandatory data object, that is, when the first channel state management command includes an operation identifier (i.e., b1=1) for opening the periodically provided channel state, the first period must exist, and when the first channel state management command includes an operation identifier (b1=0) for closing the periodically provided channel state, the first period does not exist. In the first period, the time unit and the time interval collectively represent the duration of the first period, for example, the time unit is second, and the number of time units in the time interval is 30, and then the duration of the first period is 30 seconds.
In the command qualifier, b2 is a period modification function identifier, and is used for identifying whether the UICC allows the mobile equipment to modify a preset first period when the first period exists. b2 is 0, indicating that modification of the first period is not allowed; b2 is 1, indicating that modification of the first period is allowed.
In some embodiments, the step of determining a status provision period based on the first channel status management command comprises:
in the event that the period modification function identifies that modification of the first period is not allowed, it is determined that the first period provides a period for the state. In the event that the cycle modification function is identified as allowing modification of the first cycle, a determination is made based on the device operational data as to whether providing BIP channel status based on the first cycle is supported. In the case of no support, determining a second period based on the first period, and determining the second period as a status providing period; in the case of support, the first period is determined to be a state providing period.
The device operation data may be any one or more of sleep data, update data, CPU occupation data, memory occupation data, and the like of the mobile device.
The mobile device judges whether BIP channel state is supported based on the first period based on the device operation data, so that the mobile device can conveniently and reasonably schedule the data to be processed, and preparation is made for the BIP channel state provided in the follow-up period. The mobile device determining, based on the first period, a second period when it is determined based on the device operation data that the BIP channel state is not supported based on the first period, including: and acquiring all supported standby periods based on the equipment operation data, and determining a standby period with the time length closest to the first period preset by the UICC and the time length smaller than the first period from all supported standby periods to determine a second period.
Step S202, the current BIP channel state of the BIP channel is obtained.
The current BIP channel state comprises any one or more of state information such as a connection establishment state, an activation state, whether abnormality exists or not and the like.
Step S203, generating a channel state response message based on the determined state providing period and the current BIP channel state of the BIP channel.
In some embodiments, the channel state response message may be named "Terminal Response (for Get Channel Status Interval)". The command structure of the channel state response message is as follows:

The command qualifier in the channel state response message is the same as the command qualifier data field requirements in the first channel state management command, and the detailed description is described above for the command qualifier in the first channel state management command.
The BIP channel state in the channel state response message is a conditional mandatory data object that must exist when b1=1 in the command qualifier. And, the BIP channel state in the channel state response message is the channel state of the BIP channel provided to the UICC for the first time after the mobile device receives the first channel state management command.
The status providing period in the channel status response message is an optional data object, and in the case that b2=1 in the command qualifier and the mobile device determines that the BIP channel status providing based on the first period is not supported, the status providing period is the second period; in the case where b2=0 in the command qualifier, or in the case where b2=1 in the command qualifier and the mobile device determines that the BIP channel state is not supported based on the first period, the state providing period is the above-described first period.
In one embodiment, before sending the channel state event download command to the UICC, the BIP channel state is acquired every one state providing period, and the channel state event download command is generated based on the BIP channel state acquired in the current state providing period. The channel state event download command may be named "Envelope-Channel Status Intervally". The command structure of the channel state event download command further comprises: an event download label field, a length field, an event list field, and a device identification field. The event download tag field is used to identify a command type, for example, the command type is an event download command; the length field is used for indicating the total byte length of the channel state event download command; the event list is used for identifying the downloaded event type, for example, the downloaded event type is a BIP channel state event provided periodically; the device identifier is used for representing identifiers of both communication parties corresponding to the channel state event downloading command, and comprises an initial end device identifier and a destination end device identifier, wherein the initial end device identifier is an identifier corresponding to the mobile device, and the destination end device identifier is an identifier corresponding to the UICC.

step S801, the UICC needs to perform remote data transmission, and establishes a BIP channel through the mobile device.
The mobile device selects an available data bearer when the BIP channel is established, and allows the UICC and the remote server to perform data transmission on the BIP channel through the available data bearer.
Step S802, the UICC generates a first channel state management command under the condition that the mobile device is required to provide the channel state of the BIP channel according to service requirements.
The first channel state management command includes an operation identifier for starting to periodically provide channel states. The command structure of the first channel state management command is described in detail in the foregoing embodiments of the present invention.
Step S803, the UICC sends the first channel state management command to the mobile device.

Step S806, the mobile device generates a channel state response message based on the determined state providing period and the current BIP channel state of the BIP channel.
Step S807, the mobile device sends a channel status response message to the UICC.
Step S808, the UICC receives the channel state response message, acquires the BIP channel state, and determines the state providing period determined by the mobile device.
Step S809, after sending the channel state response message to the UICC, the mobile device sends a channel state event download command to the UICC every one state providing period.
The channel state event download command includes a BIP channel state acquired in a current state providing period.
