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.

Claims (68)

1. A method of wireless communication at a base station, comprising:

identifying a service type including a quality of service (QoS) class identifier (QCI) of a mobile device;

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:

adjusting the set of handover parameters based at least in part on the determined current performance metric and the number of characteristics of the mobile device.

12. The method of claim 9 , wherein the number of characteristics of the mobile device comprise a mobile device model.

13. The method of claim 1 , wherein the determined current performance metric comprises at least one of: intra-frequency handover counts, inter-frequency handover counts, ping-pongs, inter radio access technology (RAT) triggers, single radio voice call continuity (SR-VCC) triggers, radio resource control (RRC) connection reestablishment occurrences, robust header compression (RoHC) related efficiency, RoHC related mode changes, block error rate (BLER), physical downlink shared channel (PDSCH)/physical uplink shared channel (PUSCH) resource block utilization, physical downlink control channel (PDCCH) utilization, a number of users per service type, or a combination thereof.

14. An apparatus for wireless communication at a base station, comprising:

means for identifying a service type including a quality of service (QoS) class identifier (QCI) of a mobile device;

means for determining a set of handover parameters for the mobile device based at least in part on the service type and QCI;

means for determining a current performance metric associated with the identified service type and QCI;

means for adjusting the set of handover parameters based at least in part on the determined current performance metric; and

means for transmitting, to the mobile device, a mobility message based at least in part on the adjusted set of handover parameters.

15. The apparatus of claim 14 , further comprising:

means for selecting a measurement configuration based at least in part on the adjusted set of handover parameters.

16. The apparatus of claim 15 , further comprising:

means for excluding a parameter from the measurement configuration based at least in part on the determined current performance metric.

17. The apparatus of claim 14 , further comprising:

means for selecting a handover target based at least in part on the determined current performance metric.

18. The apparatus of claim 14 , further comprising:
