CQRS 中一次事务中的多个聚合根创建

我想知道如何在 CQRS 中创建多个聚合根。

示例：我有一个手机聚合根和 Simcard 聚合根。身份证号码这些聚合应该是订阅聚合根的一部分。

我需要创建一个基于 SimCard 和 Handset 的订阅聚合。系统中不存在 SimCard 和 Handset 聚合。它们是在创建订阅时创建的。删除订阅后，SimCard 和手机不会被删除。业务原因：用户可能会在同一手机中插入不同的 SimCard，或者手机支持双 SimCard。

业务规则：电话号码应该是唯一的。手机序列号应该是唯一的。一项订阅与一部手机相关联一部手机与 1 个或多个电话号码相关联。

Class Handset { 
  String serialNumber 
 Handset(UUID id,serialNumber){ 
    super(id); 
    this.serialNumber=serialNumber; 
} 
} 

Class SimCard{ 
  String phoneNumber 
  SimCard(UUID id, String phoneNumber){ 
     super(id); 
        this. phoneNumber= phoneNumber;
  } 
 } 

Class Subscription { 
     UUID id 
     UUID deviceid 
      UUID simCardid 

    Subscription (UUID id, UUID deviceid, UUID simCardid){ 
             Super(id); 
             This. Deviceid= deviceid; 
             This. simCardid= simCardid; 
     } 
     }

I would like to know how multiple aggregate root are created in CQRS.

Example: I have a handset aggregate root and Simcard aggregate root. The id
from these aggregate should be part of subscription aggregate root .

i need to create a Subscription aggregate based on SimCard and an Handset.SimCard and Handset aggregate do not exist in the system . they are created when Subscription is created .
When Subscription is deleted SimCard and Handset is not deleted.
Business reason: user might insert different SimCard into the same Handset or the handset supports dual SimCards.

business rule :
Phone number should be unique.
Handset serialNumber should be unique.
One subscription is associated with one handset
One handset is associated with 1 or more phone number.

Class Handset { 
  String serialNumber 
 Handset(UUID id,serialNumber){ 
    super(id); 
    this.serialNumber=serialNumber; 
} 
} 

Class SimCard{ 
  String phoneNumber 
  SimCard(UUID id, String phoneNumber){ 
     super(id); 
        this. phoneNumber= phoneNumber;
  } 
 } 

Class Subscription { 
     UUID id 
     UUID deviceid 
      UUID simCardid 

    Subscription (UUID id, UUID deviceid, UUID simCardid){ 
             Super(id); 
             This. Deviceid= deviceid; 
             This. simCardid= simCardid; 
     } 
     }
