Method of supporting reactivation of a dormant session using stored service configurations
View Patent ↗A method of supporting reactivation of service instances in a dormant session. A wireless device ( 102 ) sends an Origination or Reconnect message to a Base Station ( 104 ) requesting reactivation of one, all or some of its dormant service instances. The request includes a SYNC_ID previously assigned by the BS. The Base Station sends a message to a Packet Control Function ( 106 ) requesting stored service configuration information. The Packet Control Function responds with the requested information and channel resources are allocated for each service instance supported for the session.
1. A method of supporting reactivation of a dormant packet data session comprising:
a base station receiving an identifier corresponding to stored service configuration information from a mobile station with a dormant packet data session;
the base station requesting stored service configuration information from a packet control function, wherein the request comprises the identifier corresponding to the stored service configuration information received from the mobile station;
the base station receiving a first message from the packet control function, the message containing stored service configuration information comprising at least one of a service option and a service reference identifier; and
the base station reactivating the dormant packet data session using the stored service configuration information and sending a second message containing an indication to notify a mobile station to use its stored service configuration.
2. The method of claim 1 wherein before receiving an identifier corresponding to stored service configuration information from a mobile station, the method comprises
assigning an identifier corresponding to a current service configuration of the mobile station for the session; and
sending the identifier and the corresponding current service configuration to a packet control function.
3. The method of claim 1 wherein the at least one of a service option and a service reference identifier is associated with each service instance in a mobile station's packet data session that reactivation is requested for.
4. The method of claim 1 further comprising:
sending a message to the packet control function to establish an A 8 connection for each service instance in a mobile station's packet data session that reactivation is requested for; and
receiving an indication that an A 8 connection for each service instance that reactivation is requested for has been successfully established.
5. A method of supporting reactivation of a dormant packet data session comprising:
receiving an identifier corresponding to a current service configuration of a mobile station for the session, the service configuration comprising at least one of a service option and a service reference identifier;
storing the identifier and the corresponding service configuration;
receiving a request for stored service configuration information from a base station, wherein the request comprises the identifier; and
sending the stored service configuration corresponding to the identifier to the base station.
6. The method of claim 5 wherein the at least one of a service option and a service reference identifier is associated with each service instance in the packet data session that reactivation is requested for.
7. The method of claim 5 further comprising receiving a message requesting establishment of an A 8 connection for each service instance in the packet data session that reactivation is requested for; and
sending an indication that an A 8 connection for each service instance that reactivation is requested for has been successfully established.
