Abstract

In some implementations, a method includes identifying handover from a source eNodeB (eNB) to a target eNB or reestablishment with a subsequent eNB after losing connection with an initial eNB. Time-domain measurement resource restrictions for the UE are identified. The time-domain measurement resource restriction for the UE is released in connection with identifying the handover or the reestablishment.

Claims (59)

1. A method, comprising:

setting a value of a MeasObjectEUTRA information element measSubframePatternConfigNeigh to Need OR;

identifying handover from a source eNodeB (eNB) to a target eNB or reestablishment with a subsequent eNB after losing connection with an initial eNB;

determining wireless communication in connection with the handover or the reestablishment does not include the measSubframePatternConfigNeigh information element;

identifying time-domain measurement resource restrictions for a user equipment (UE); and

in response to the determining, releasing the time-domain measurement resource restriction for the UE in connection with identifying the handover or the reestablishment.

2. The method of claim 1 , wherein releasing the time-domain measurement resource restriction comprises automatically releasing the time-domain measurement resource restriction in response to the handover or the reestablishment.

3. The method of claim 1 , wherein releasing the time-domain measurement resource restriction comprises releasing the time-domain measurement resource restriction for neighbor cells for at least one of a target primary frequency, a source primary frequency, an initial primary frequency, a subsequent primary frequency, any EUTRAN frequency, or a predetermined or preconfigured frequency.

4. User Equipment (UE), comprising:

one or more processors configured to:

set a value of a MeasObjectEUTRA information element measSubframePatternConfigNeigh to Need OR;

identify handover from a source eNodeB (eNB) to a target eNB or reestablishment with a subsequent eNB after losing connection with an initial eNB;

determine wireless communication in connection with the handover or the reestablishment does not include the measSubframePatternConfigNeigh information element;

identify time-domain measurement resource restrictions for a UE; and

in response to the determination, release the time-domain measurement resource restriction for a UE based in connection with identifying the handover or the reestablishment.

5. The UE of claim 4 , wherein the one or more processors configured to release the time-domain measurement resource restriction comprise one or more processors configured to automatically release the time-domain measurement resource restriction in response to the handover or the reestablishment.

6. The UE of claim 4 , wherein the one or more processors configured to release the time-domain measurement resource restriction comprise one or more processors configured to release the time-domain measurement resource restriction for neighbor cells for at least one of a target primary frequency, a source primary frequency, an initial primary frequency, a subsequent primary frequency, any EUTRAN frequency, or a predetermined or preconfigured frequency.

7. A computer program product encoded on a non-transitory, tangible storage medium, the product comprising computer readable instructions for causing at least one processor to perform operations comprising:

setting a value of a MeasObjectEUTRA information element measSubframePatternConfigNeigh to Need OR;

identifying handover from a source eNodeB (eNB) to a target eNB or reestablishment with a subsequent eNB after losing connection with an initial eNB;

determining wireless communication in connection with the handover or the reestablishment does not include the measSubframePatternConfigNeigh information element;

identifying time-domain measurement resource restrictions for a user equipment (UE); and

in response to the determining, releasing the time-domain measurement resource restriction for the UE in connection with identifying the handover or the reestablishment.

8. The computer program product of claim 7 , wherein the operations comprising releasing the time-domain measurement resource restriction includes operations comprising automatically releasing the time-domain measurement resource restriction in response to the handover or the reestablishment.

9. The computer program product of claim 7 , wherein the operations comprising releasing the time-domain measurement resource restriction include operations comprising releasing the time-domain measurement resource restriction for neighbor cells for at least one of a target primary frequency, a source primary frequency, an initial primary frequency, a subsequent primary frequency, any EUTRAN frequency, or a predetermined or preconfigured frequency.

10. A method, comprising:

transmitting, to a UE, instructions to set a value of a MeasObjectEUTRA information element measSubframePatternConfigNeigh to Need OR;

identifying, by a source eNB, a handover to a target eNB;

identifying time-domain measurement resource restrictions for the UE; and

transmitting, by the source eNB, a handover command with a measSubframePatternConfigNeigh information element to the UE to maintain the time-domain measurement resource restriction for the UE based on the handover.

11. The method of claim 10 , further comprising:

transmitting a request to the target eNB for information identifying a type of network; and

determining the target eNB is serviced by a Long Term Evolution (LTE) network based on a response from the target eNB, wherein the handover command indicates the target eNB is serviced by the LTE network.

12. The method of claim 11 , wherein the request is transmitted using an X2 interface or an operating and management (OAM) system.

13. The method of claim 10 , wherein the handover command indicates maintaining the time-domain measurement resource restriction for neighbor cells for at least one of a target primary frequency, a source primary frequency, or any EUTRAN frequency.

14. The method of claim 10 , wherein the handover command includes a measSubframePatternConfigNeigh information element (IE) set, by the target eNB, to release a target primary frequency, a source primary frequency, or any Evolved Universal Terrestrial Radio Access (EUTRA) frequency, the method further comprising transmitting the handover command to the UE.

15. A source eNB, comprising:

one or more processors configured to:

transmit, to a UE, instructions to set a value of a MeasObjectEUTRA information element measSubframePatternConfigNeigh to Need OR;

identify, by a source eNB, a handover to a target eNB;

identify time-domain measurement resource restrictions for the UE; and

transmit, by the source eNB, a handover command with a measSubframePatternConfigNeigh information element to the UE to maintain the time-domain measurement resource restriction for the UE based on the handover.

16. The eNB of claim 15 , the processors further configured to:

transmit a request to the target eNB for information identifying a type of network; and

determine the target eNB is serviced by an LTE network based on a response from the target eNB.

17. The eNB of claim 16 , wherein the request is transmitted using an X2 interface or an operating and management (OAM) system.

18. The eNB of claim 15 , wherein the handover command indicates maintaining the time-domain measurement resource restriction for neighbor cells for at least one of a target primary frequency, a source primary frequency, or any EUTRAN frequency.

19. The eNB of claim 15 , wherein the handover command includes a measSubframePatternConfigNeigh information element (IE) set, by the target eNB, to release a target primary frequency, a source primary frequency, or any EUTRA frequency, the one or more processors further configured to transmit the handover command to the UE.

20. A computer program product encoded on a non-transitory, tangible storage medium, the product comprising computer readable instructions for causing at least one processor to perform operations comprising:
