Abstract
A mobile communications network includes various entities, such as a mobile station, a radio network, and a packet data node. In one implementation, the mobile station is enabled for an always-on service. In response to detecting that the mobile station is an always-on mobile station, the packet-data node denies requests from the radio network to tear down a packet data session of the mobile station unless some predetermined criterion has been met.
Claims25
A method for use in a mobile communications network, comprising:
- receiving a request from a base station controller to terminate a communications session with a mobile station;
- in response to receiving the request to terminate, checking an indicator to determine whether the communications session is to be maintained for the mobile station;
- and
- in response to determining that the communications session is to be maintained for the mobile station, generating a message to deny the request to terminate the communications session.
An article comprising at least one storage medium containing instructions that when executed cause a node to:
- receive, from a wireless network, a request to terminate a communications session with a mobile station;
- in response to receiving the request to terminate, checking an indicator to determine whether the communications session is to be maintained for the mobile station;
- and
- in response to determining that the communications session is to be maintained for the mobile station, generating a message to deny the request to terminate the communications session.
A node comprising:
- an interface to receive, from a wireless network, a request to terminate a communications session with a mobile station;
- and
- in response to the request, a controller to check an indicator to determine whether the communications session is to be maintained for the mobile station, and in response to determining that the communications session is to be maintained for the mobile station, send a message to the wireless network to deny the request to terminate the communications session.
