Cell reselection
View Patent ↗An LTE cellular network having management mobility servers (MMEs), base stations (enodeBs) and mobile user equipment (UE). The network supporting two groups of mobile device subscribers; subscribers of a macrocell network and subscribers of a small cell network. The base stations being configured to broadcast network information and device configuration information to the mobile devices through System Information Block messages. The base stations being configured to selectively send override parameters to subscribers of the mobile devices to alter the idle mode reselection processing to prefer connections to the small cell network.
1. A method for providing dedicated idle mode reselection parameters to a cellular device in a cellular network, the method comprising a base station of the cellular network performing the following:
determining a subscriber group for the cellular device;
identifying a set of operating parameters associated with the cellular device in accordance with the determined subscriber group, wherein the operating parameters alter the idle mode reselection behavior of the cellular device; and
sending the set of operating parameters so as to override any existing parameter values stored at the cellular device,
wherein the cellular device performs idle mode reselection in accordance with the overriding operating parameters.
2. A method according to claim 1 , wherein different sets of operating parameters can be mapped to the cellular device at different times.
3. A method according to claim 1 , wherein the operating parameters alter the timing and frequency that the cellular device will perform idle mode reselection.
4. A method according to claim 1 wherein the cellular device can access two different cellular networks and the operating parameters bias the cellular device to reselect to one of the two different cellular networks.
5. Apparatus for providing dedicated idle mode reselection parameters to a cellular device in a cellular network, the apparatus comprising:
a base station comprising a processor and a memory and configured to:
determine a subscriber group for the cellular device;
identify a set of operating parameters associated with the cellular device in accordance with the determined subscriber group, wherein the operating parameters alter the idle mode reselection behavior of the cellular device; and
send the set of operating parameters to the cellular device so as to override any existing parameter values stored at the cellular device,
wherein the cellular device performs idle mode reselection in accordance with the overriding operating parameters.
6. Apparatus according to claim 5 , wherein different sets of operating parameters can be mapped to the cellular device at different times.
7. Apparatus according to claim 5 , wherein the operating parameters alter the timing and frequency that the cellular device will perform idle mode reselection.
8. Apparatus according to claim 5 , wherein the cellular device can access two different cellular networks and the operating parameters bias the cellular device to reselect to one of the two different cellular networks.
