Abstract

A method in a mobile wireless communications network including sending (210) a reselection communication from a mobile station to the network, and receiving (220), from the network in response to the reselection communication, cell reselection assistance information, for example, a new cell assignment.

Claims

1. A method in a mobile wireless communication device, the method comprising:

sending a network controlled/assisted reselection mode support communication to a network, the network controlled/assisted reselection mode support communication indicating whether the mobile wireless communication device is capable of performing reselection prediction;

receiving a reselection control communication from the network in response to sending the network controlled/assisted reselection mode support communication to the network;

disabling a reselection parameter on the mobile wireless communication device in response to receiving the reselection control communication,

wherein the reselection parameter is a cell ranking parameter.

2. The method of claim 1, disabling reselection in the mobile wireless communication device based on adjacent cell information in response to the reselection control communication from the network.

3. The method of claim 1, reselecting using a reselection predictor on the mobile wireless communication device when a packet broadcast control channel is present in a serving cell.

4. The method of claim 1 further comprising reselecting based on the reselection control communication from the network.

5. A method in a mobile wireless communication network, the method comprising:

receiving a network reselection mode support communication from a mobile station;

sending a reselection control communication to the mobile station in response to receiving the network reselection mode support communication from the mobile station,

the reselection control communication instructing the mobile station to disable reselection based on adjacent cell information;

sending a reselection control communication includes instructing the mobile station to disable a cell ranking parameter on the mobile station in response to receiving the reselection control communication.

6. A method in a mobile wireless communication device, the method comprising:

sending a network controlled/assisted reselection mode support communication to a network, the network controlled/assisted reselection mode support communication indicating whether the mobile wireless communication device is capable of performing reselection prediction;

receiving a reselection control communication from the network in response to sending the network controlled/assisted reselection mode support communication to the network;

receiving a new reselection threshold, reselecting using a reselection predictor on the mobile wireless communication device after receiving the new reselection threshold in the absence of a packet broadcast control channel in a serving cell.

7. A method in a mobile wireless communication device, the method comprising:

sending a network controlled/assisted reselection mode support communication to a network, the network controlled/assisted reselection mode support communication indicating whether the mobile wireless communication device is capable of performing reselection prediction;

receiving a reselection control communication from the network in response to sending the network controlled/assisted reselection mode support communication to the network;

reselecting using a default warning interval upon satisfying a reselection threshold in the absence of a packet broadcast control channel in a serving cell and in the absence of receipt of a new reselection threshold from the network.

8. A method in a mobile wireless communication device, the method comprising:

sending a network controlled/assisted reselection mode support communication to a network, the network controlled/assisted reselection mode support communication indicating whether the mobile wireless communication device is capable of performing reselection prediction;

receiving a reselection control communication from the network in response to sending the network controlled/assisted reselection mode support communication to the network;

disabling a reselection parameter on the mobile wireless communication device in response to receiving the reselection control communication,

wherein the reselection parameter is a C32 criterion parameter.

9. A method in a mobile wireless communication device, the method comprising:

sending a network controlled/assisted reselection mode support communication to a network, the network controlled/assisted reselection mode support communication indicating whether the mobile wireless communication device is capable of performing reselection prediction;

receiving a reselection control communication from the network in response to sending the network controlled/assisted reselection mode support communication to the network;

disabling a reselection parameter on the mobile wireless communication device in response to receiving the reselection control communication;

reselecting using a default warning interval upon satisfying a reselection threshold in the absence of a packet broadcast control channel in a serving cell and in the absence of receipt of a new reselection threshold from the network.
