Abstract

Methods, systems, and devices are described for wireless communication at a base station. A base station may identify a service type of a mobile device (e.g., voice, web-browsing, or video download). The base station may then determine handover or measurement parameters for the mobile device based on the service type. The base station may also determine a performance metric of the service type. The base station may then adjust the set of parameters based at least in part on the performance metric. In some cases, the base station may select a measurement configuration based on the adjusted parameters.

First claim

determining a set of handover parameters for the mobile device based at least in part on the service type and QCI;
determining a current performance metric associated with the identified service type and QCI;
adjusting the set of handover parameters based at least in part on the determined current performance metric; and
transmitting, to the mobile device, a mobility message based at least in part on the adjusted set of handover parameters.

2. The method of claim 1 , further comprising:
selecting a measurement configuration based at least in part on the adjusted set of handover parameters.

3. The method of claim 2 , further comprising:
excluding a parameter from the measurement configuration based at least in part on the determined current performance metric.

4. The method of claim 1 , further comprising:
selecting a handover target based at least in part on the determined current performance metric.

5. The method of claim 1 , further comprising:
identifying a number of services supported by the base station associated with the set of handover parameters.

6. The method of claim 5 , wherein adjusting the set of handover parameters comprises:
adjusting the set of handover parameters based at least in part on the determined current performance metric and the number of services supported by the base station.

7. The method of claim 1 , further comprising:
identifying a number of services supported by the mobile device.

8. The method of claim 7 , wherein adjusting the set of handover parameters comprises:
adjusting the set of handover parameters based at least in part on the determined current performance metric and the number of services supported by the mobile device.

9. The method of claim 1 , further comprising:
identifying a number of characteristics of the mobile device.

10. The method of claim 9 , further comprising:
determining a network performance associated with the number of characteristics of the mobile device.

11. The method of claim 9 , wherein adjusting the set of handover parameters comprises:
