    摘要: Wireless data services such as wireless email are becoming common, and in particular, “always-on” systems, where new email is automatically forwarded by the service provider to the wireless device. The problem is that there is no effective mechanism for implementing “always-on” systems when the user is moving around a network, or from one network to another. The invention addresses this problem by generating a session key at the service provider's system for a given data session, and returning this session key to the mobile device. Each time the mobile device communicates with the service provider, it enters this session key into a field that will simply pass through the communication network to the service provider. This allows the service provider to manage the data session, preparing proper accounting records and directing the deletion of stale data sessions on network resources.

The housing has a positioning member (316). The battery cover latching assembly includes a latching member (201) and a resilient member (202). The latching member has a locking portion (2019). The resilient member has a first end (2021) and a second end (2022). The first end is mounted in the latching member. The second end is mounted with the battery cover. The latching member is installed in the receiving hole. The locking portion is engaged with the positioning member thereby mounting the battery cover to the housing. When the latching member is forced to move relative to the battery cover, the resilient member is twisted thereby making the latching member to move in an opposing direction.
