    • A system and method for sharing location data amongst wireless communication devices uses a token system to grant permission to share location data. The tokens may be created automatically as the result of user activation of a different function. Location data may be exchanged when two wireless communication devices, authorized to exchange location data, are within a predetermined distance from each other. Location data may also be automatically exchanged upon the occurrence of a scheduled calendar event within a wireless communication device. Location data may be exchanged a single time or can be exchanged on a continuous or periodic basis so long as the token still exists. The token may be destroyed manually by some user activity or may be terminated automatically.
    • 用于在无线通信设备之间共享位置数据的系统和方法使用令牌系统来授予共享位置数据的权限。 令牌可以由用户激活不同功能而自动创建。 当授权交换位置数据的两个无线通信设备在彼此之间的预定距离内时,可以交换位置数据。 在无线通信设备内发生调度的日历事件时,位置数据也可以自动交换。 只要令牌仍然存在,位置数据可以单独交换或者可以在连续或周期性的基础上进行交换。 令牌可能会被某些用户活动手动销毁,或者可能会被自动终止。
