SERVICE REQUEST DEVICE WIRELESS ACCESS DETACH AND BEARER DEACTIVATION METHODS WITHOU LOSS OF INTERNET PROTOCOL CONNECTIVITY
First Claim
1. A network device comprising:
- an Internet protocol (IP) connectivity generator that generates an IP connectivity indicator, the IP connectivity indicator indicating IP connectivity for a service request device (SRD);
a transmit module that transmits said IP connectivity indicator to a remote network device before at least one of;
detachment of said SRD; and
deactivation of a bearer corresponding to a first session and a tunnel between said SRD and said remote network device; and
a control module that facilitates said at least one of detachment of said SRD and deactivation of said bearer while maintaining IP connectivity corresponding to at least one of;
attachment of said SRD; and
activation of a second session of said SRD based on said IP connectivity indicator.

Abstract
A network device includes an Internet protocol (IP) connectivity generator that generates an IP connectivity indicator. The IP connectivity indicator indicates IP connectivity for a service request device (SRD). A transmit module transmits the IP connectivity indicator to a remote network device before at least one of detachment of the SRD and deactivation of a bearer corresponding to a first session and a tunnel between the SRD and the remote network device. A control module facilitates the detachment of the SRD and deactivation of the bearer while maintaining IP connectivity. The IP connectivity corresponding to at least one of attachment of the SRD and activation of a second session of the SRD based on the IP connectivity indicator.
