Abstract
Systems, methods and computer software are disclosed for resolving multiple contexts for a User Equipment (UE) in a wireless network. In one embodiment a method includes maintaining, for a coordinating node hosting a first Radio Access Technology (RAT) controller and a second RAT controller simultaneously, a centrally maintained database; determining, based on the contents of the centrally maintained database, when the UE is registering with the second RAT controller while currently registered with the first RAT controller; and sending, by the second RAT controller, a deregistration command to the first RAT controller the UE was registered with, wherein context is freed and wherein resources held at both the coordinating node and at a base station are freed.
Claims18
A method for resolving multiple contexts for a User Equipment (UE) in a wireless network, comprising:
- maintaining, for a coordinating node hosting a first Radio Access Technology (RAT) controller and a second RAT controller simultaneously, a centrally maintained database;
- determining, based on the contents of the centrally maintained database, when the UE is registering with the second RAT controller while currently registered with the first RAT controller;
- and
- sending, by the second RAT controller, a deregistration command to the first RAT controller the UE was registered with, wherein context is freed and wherein resources held at both the coordinating node and at a base station are freed.
A system for resolving multiple contexts for a User Equipment (UE) in a wireless network, comprising:
- a UE;
- a first Radio Access Technology (RAT) controller in communication with the UE;
- a second Radio Access Technology (RAT) controller in communication with the UE;
- a coordinating node hosting a first Radio Access Technology (RAT) controller and a second RAT controller simultaneously, and maintaining a central database;
- the coordinating host determines, based on the contents of the centrally maintained database, when the UE is registering with the second RAT controller while currently registered with the first RAT controller;
- and
- wherein the second RAT controller sends a deregistration command to the first RAT controller the UE was registered with, and wherein context is freed and wherein resources held at both the coordinating node and at a base station are freed.
A non-transitory computer-readable medium containing instructions for resolving multiple contexts for a User Equipment (UE) in a wireless network which, when executed, cause a coordinating node to perform steps comprising:
- maintaining, for a coordinating node hosting a first Radio Access Technology (RAT) controller and a second RAT controller simultaneously, a centrally maintained database;
- determining, based on the contents of the centrally maintained database, when the UE is registering with the second RAT controller while currently registered with the first RAT controller;
- and
- sending, by the second RAT controller, a deregistration command to the first RAT controller the UE was registered with, wherein context is freed and wherein resources held at both the coordinating node and at a base station are freed.
