Wireless device determination that conditions are fullfilled prior to utilizing mobility history list

1. A wireless device configured to interact with a radio access network (RAN) node and a core network (CN) node, the wireless device comprising:

a processor; and,

a memory that stores processor-executable instructions, wherein the processor interfaces with the memory to execute the processor-executable instructions, whereby the wireless device is operable to:

obtain at least one threshold identifying when the wireless device qualifies to use a mobility history list, wherein the obtain operation further comprises:

receiving, from the RAN node, an update to the at least one threshold where the update is based on a start of an overload situation in a wireless communication network; and

receiving, from the RAN node, another update to the at least one threshold where the another update is based on an end of the overload situation in the wireless communication network;

determine based on the at least one threshold whether the wireless device qualifies to use the mobility history list; and

based on a determination that the wireless device is to use the mobility history list, transmit a message including a list of one or more cells visited by the wireless device.

2. The wireless device of claim 1 , wherein the obtain operation further comprises at least one of the following:

receiving, from the RAN node, the at least one threshold in System Information (SI) on a broadcast channel;

receiving, from the CN node, the at least one threshold in dedicated signaling;

receiving, from the RAN node, the at least one threshold in dedicated signaling; and

pre-configuring the at least one threshold within the wireless device.

3. The wireless device of claim 1 , wherein the wireless device is operable to perform the determine operation at power on or upon detecting a new cell.

4. The wireless device of claim 1 , wherein the determine operation further comprises:

determining whether there is an exception to using or not using the mobility history list independent of whether or not the wireless device qualifies based on the at least one threshold to use the mobility history list.

5. A method in a wireless device configured to interact with a radio access network (RAN) node and a core network (CN) node, the method comprising:

obtaining at least one threshold identifying when the wireless device qualifies to use a mobility history list, wherein the obtaining step further comprises:

receiving, from the RAN node, an update to the at least one threshold where the update is based on a start of an overload situation in a wireless communication network; and

receiving, from the RAN node, another update to the at least one threshold where the another update is based on an end of the overload situation in the wireless communication network;

determining based on the at least one threshold whether the wireless device qualifies to use the mobility history list; and

based on a determination that the wireless device is to use the mobility history list, transmitting a message including a list of one or more cells visited by the wireless device.

6. The method of claim 5 , wherein the obtaining step further comprises at least one of the following:

receiving, from the RAN node, the at least one threshold in System Information (SI) on a broadcast channel;

receiving, from the CN node, the at least one threshold in dedicated signaling;

receiving, from the RAN node, the at least one threshold in dedicated signaling; and

pre-configuring the at least one threshold within the wireless device.

7. The method of claim 5 , wherein the wireless device is operable to perform the determining step at power on or upon detecting a new cell.

8. The method of claim 5 , wherein the determining step further comprises:

determining whether there is an exception to using or not using the mobility history list independent of whether or not the wireless device qualifies based on the at least one threshold to use the mobility history list.
