Abstract

Some embodiments disclose methods for classifying user equipment in a network, comprising: recording a first number of times a tracking area identity has changed for a user equipment device during a period of time based on messages exchanged between the user equipment device and a mobility management entity; recording a second number of times the user equipment device is paged during a second period of time; classifying the user equipment device into one of at least three categories based on the first and second recorded numbers; generating a tracking area identity list for the user equipment based device on its category; and sending the generated tracking area identity list to the user equipment device.

Claims

1. A method for classifying user equipment in a network, comprising:

recording a first number of times a tracking area identity has changed for a user equipment device during a period of time based on messages exchanged between the user equipment device and a mobility management entity;

recording a second number of times the user equipment device is paged during a second period of time;

classifying the user equipment device into one of at least three categories based on the first and second recorded numbers;

generating a tracking area identity list for the user equipment based device on its category; and

sending the generated tracking area identity list to the user equipment device.

2. The method of claim 1, wherein the at least three categories include a first category of high mobility, high paged devices;

a second category of high mobility, low paged devices; and

a third category of low mobility devices.

3. The method of claim 1, wherein the first category includes mobile phones, the second category includes in-vehicle security devices, and the third category includes at home devices.

4. The method of claim 1, the user equipment device including one of a mobile phone, an in-vehicle security device, and an at home device.

5. The method of claim 1, wherein the messages exchanged between the user equipment device and the mobility management entity include at least one of tracking area updates and attach messages.

6. The method of claim 1, further comprising, based on the user equipment device being classified as a high mobility, low paged device, generating the tracking area identity list based on stored information indicating probabilities of the user equipment device moving between various tracking areas.

7. The method of claim 6, wherein the stored information is based on previous tracking area updates of the user equipment device.

8. The method of claim 6, wherein the stored information is based on previous changes of tracking areas of the user equipment device.

9. The method of claim 1, further comprising, based on the user equipment device being classified as a low mobility device, generating the tracking area identity list based on an overlap of tracking areas between the a first tracking area group and a second tracking area group.

10. The method of claim 1, further comprising, based on the user equipment device being classified as a low mobility device, generating the tracking area identity list based on a tracking area group defined as a number of tracking areas supported by a same set of a base transceiver stations.
