Mobile Operator account management in Windows 10

[アーティクル]
04/25/2022

This topic describes the mobile operator account management experience provided by Windows, which can be extended with Mobile Plans.

Basic account management experience

This section describes the options to configure what the View my account link shows in the Windows Connection Manager, also known as also known as the network flyout.

The View my account link could be configured to:

Launch a web browser and open a defined web page.
Launch the Mobile Plans app and open the mobile operator web portal.

Once you have decided on one of these options, please request a COSA database update to implement the right behavior. For more info, please see Planning your desktop COSA database submission.

The following settings apply for the above options:

AccountExperienceURL. This parameter defines the web page.
AppID. This parameter defines which app is launched. To use the Mobile Plans app, configure Microsoft.OneConnect_8wekyb3d8bbwe!App.

The following image shows an example of the network flyout:

Enhanced account management experience

By implementing the enhanced account management experience, you can offer these benefits to your customers:

Customers can see how much data is available, and the amount of time left until their subscription expires, in the network flyout.
Customers can top up their prepaid subscriptions over mobile connectivity, even when they run out of prepaid balance or their subscriptions has expired.
You can manage your network flyout offering based on customer's subscription status.

These experiences build on top of the basic account management experience, which is the default experience in the device network flyout.

Depending on the information that is received from GetBalance API calls, the network flyout behaves differently, which enhances the user experience.

The network flyout has the following elements:

Connect with a data plan. This launches the Mobile Plans app.
View my account. Behaves based on the basic account management experience.
Balance information. Shows the balance available, which is provided in your GetBalance response.

The following image shows these network flyout elements. Connect with a data plan corresponds with A, View my account corresponds with B, and Balance information corresponds with C.

To provide the right information in the network flyout, MOs provide Type and Balance (dataRemainingMB and timeRemaining) information as defined in the GetBalance API section.

The following table provides a reference between the GetBalance response type and what is displayed in the network flyout.

GetBalance response type	Network flyout shows...
MODIRECT	"View my account" only with no balance information
MODIRECTPAYG	"View my account" and balance information
NONE	"Connect with a data plan"
NOTSUPPORTED	"View my account" only

GetBalance API

Important

Please request a Windows COSA update to enable Get Balance in Windows.

The GetBalance API queries current subscription status, controls whether the Mobile Plans experience is available on the device, and shows remaining data and time in the network flyout for prepaid subscriptions. The following diagram shows the high-level flow for the GetBalance API.

Resource model

Communication between the Mobile Plans service and the Mobile Operator API involves manipulating the resources in the following diagram. Explanations for each resource are in the tables following the diagram.

SIM resource

Note

The SIM resource does not currently support “create,” “read,” “update,” or “delete” operations.

JSON property	Type	Description
Iccid	String	The ICCID of the profile that has been created.

Balance resource

JSON property	Type	Description
id	String	Mobile operator internal id, to track the transaction
Type	Enum	Possible values: MODIRECT: Indicates if the user balance is MO Direct. MODIRECTPAYG: Indicates if the user balance is MO Direct PAYG. NONE: Indicates the user has no balance. When the remaining balance is 0 but the plan has not expired, we expect to receive "NONE" so that the user can purchase data plans. NOTSUPPORTED: Indicates the SIM is not supported by the Mobile Plans experience. "NOTSUPPORTED" is used when the SIM should not be in the*Mobile Plans supported range. We will turn off the Mobile Plans experience in the network flyout and return a generic error message in the Mobile Plans app when we receive this type.
dataRemainingInMB	Double	The data remaining in the current user plan, in MB.
timeRemaining	String	The time duration specified in ISO 8601.

Headers

The following headers may be included in every request from the Mobile Plans service to the mobile provider’s endpoint.

Header name	Value	Description
X-MS-DM-TransactionId	String	The TransactionId to uniquely identify this request/response interaction between the Mobile Plans service and the MO service.
Authorization (optional)	String	A basic authentication string optionally provided by the MO.

Error codes

The table below defines the error codes that should be used in the HTTP response.

Error code	Description
HTTP 200 (OK)	The operation completed successfully. This code should also be used to indicate if the user has 0 balance in the specified location, which should be done using dataRemainingInMB=0 and timeRemaining=”PT0S” with HTTP 200.
HTTP 201 (Created)	Indicates that the operation completed successfully and the resource was created successfully.
HTTP 400 (Bad Request)	Used for an invalid query parameter, invalid header, or invalid payload. In the response body, the parameter that is incorrect should be indicated. For example, if an invalid fieldsTemplate is specified, this error code must be returned with details in the response body.
HTTP 401 (Unauthorized)	Authentication credentials were incorrect or invalid. This can occur when the basic auth credentials passed are incorrect.
HTTP 403 (Forbidden)	The client certificate is untrusted or invalid. If the client certificate included as a part of MTLS is invalid, HTTP 403 should be returned.
HTTP 404 (Not Found)	The MO service should return this error when the resource doesn’t exist. This can occur when an incorrect ICCID is sent. This should not be used to indicate that the user doesn’t have a balance in the specified location, which is indicated with HTTP 200 (OK).
HTTP 409 (Conflict)	Used if a TransactionId is repeated.
HTTP 429 (Too many requests)	Used by the MO service to indicate that the Mobile Plans service is sending too many requests within the specified amount of time. In the response, the MO service must use the Retry-After header to indicate the time after which the Mobile Plans service should retry for the resource. In the response body, optional details can be provided.
HTTP 500 (Internal Error)	Something unexpected happened on the MO service. The MO service should include the cause of error whenever possible so that it can be used for further debugging as needed.

GetBalance API specification

The GetBalance API is called when network flyout is displayed in the Windows device. The Mobile Plans service is a proxy for this communication.

This call is done with an HTTP request, where moBaseUrl is the endpoint of the MO-hosted service and sim id is the ICCID:

GET https://{moBaseUrl}/sims/{sim id}/balances?fieldsTemplate=basic&limit=1&location=US HTTP/1.1

Query parameters:

Query parameter name	Value	Description
location	String	Optional. The location where the user balance is being queried. If not specified, all active balances are expected. Note The location parameter is case-sensitive.
limit	Integer	Optional. The maximum count of balances to be returned. If not specified, all balances should be returned.
fieldsTemplate	Enum	Specifies the list of fields that must be returned in the resource. Possible values: Basic: type, dataRemainingInMB, and timeRemaining in the Balance resource must be returned. Full: All properties in the Balance resource must be returned.

The following series of examples show the call flow for the GetBalance API.

Example 1: Returning the first balance that is available for the user in US

GET https://moendpoint.com/v1/sims/iccid: 8988247000100003319/balances?fieldsTemplate=basic&limit=1&location=us HTTP/1.1
X-MS-DM-TransactionId: “MSFT-12345678-1234-1234-1234-123456789abc”

HTTP response:

HTTP/1.1 200 OK
Content-type: application/json
X-MS-DM-TransactionId: “12345”

{
“balances”: [
    {
         “id”: “23445”,
         “type”: “MODIRECTPAYG”,
         “dataRemaininginMB”: 123.0,
         “timeRemaining”: “P23DT23H”
    }
  ]
}

If successful, this method will return the balance of the user.

Response JSON:

Example 2: The expected response for a SIM that is in the COSA ICCID range but should not be supported by Mobile Plans

HTTP request:

GET https://{moBaseUrl}/sims/{sim id}/balances?fieldsTemplate=basic&limit=1&location=US
HTTP/1.1

Response JSON:

HTTP/1.1 200 OK
Content-type: application/json
X-MS-DM-TransactionId: “12345”

{
“balances”: [
    {
         “id”: “23445”,
         “type”: “NOTSUPPORTED”,
         “dataRemaininginMB”: 0.0,
         “timeRemaining”: “PT0S”
    }
  ]
}

Authentication

Communication between the Mobile Plans service and the Mobile Operator API is performed via certificate based client authentication.

A certificate with the following Subject Name will be passed during the call to the Mobile Operator API:

C=US, ST=WA, L=Redmond, O=Microsoft Corporation, CN=partners.datamart.windows.com

The certificate chains to this CA: DigiCert Global Root G2.

We recommend that all Mobile Operators validate that the Subject Name of the certificate matches the one above.
