Method and system for indicating frequency for reporting a GERAN CGI
View Patent ↗The present disclosure provides for methods and systems for indicating a frequency for reporting a GERAN CGI. These include the relaxation of the single measurement object per frequency principle; an indication of ARFCN for CGI reading; measurement interruption avoidance; implicit indications of ARFCN for CGI reading; the use of a different object than a measurement object to report the cell for which to report the CGI; the use of a measurement configuration report to indicate the CGI cell or the selection of an ARFCN using to find rules at the UE.
1. A method at a user equipment comprising:
receiving, at the user equipment, a measurement object from a network element for modifying an existing measurement object at the user equipment, the received measurement object defining at least one carrier frequency on which the user equipment is to perform measurements;
if the received measurement object is modified only to configure cell global identifier reporting, maintaining at least one of a measurement reporting entry, associated timers and any associated information; and
if the received measurement object is modified other than to only configure cell global identifier reporting, removing the measurement reporting entry, stopping any associated timers and resetting said any associated information.
2. The method of claim 1 , wherein the received measurement object contains an information element to configure cell global identifier reporting.
3. The method of claim 1 , wherein the received measurement object contains an explicit indication for a frequency for reporting the cell global identifier.
4. The method of claim 3 , wherein the explicit indication is a field within an information element for the received measurement object.
5. The method of claim 4 , wherein the explicit indication is an index value.
6. The method of claim 3 , wherein the received measurement object contains an implicit indication for a frequency for reporting the cell global identifier.
7. The method of claim 6 , wherein the implicit indication uses an ordering of frequencies within the measurement object.
8. The method of claim 7 , wherein the implicit indication is a frequency at a start of a list of frequencies.
9. The method of claim 6 , wherein the implicit indication is a starting frequency value.
10. The method of claim 1 , further comprising receiving a new measurement identifier and reporting configuration for reporting the cell global identifier from the network element.
11. A user equipment comprising:
a processor, and
a communications subsystem,
wherein the user equipment is configured to:
receive a measurement object from a network element for modifying an existing measurement object at the user equipment, the received measurement object defining at least one carrier frequency on which the user equipment is to perform measurements; and
if the received measurement object is modified only to configure cell global identifier reporting, maintain at least one of a measurement reporting entry, associated timers and any associated information; and
if the received measurement object is modified other than to only configure cell global identifier reporting, remove the measurement reporting entry, stop any associated timers and reset said any associated information.
12. The user equipment of claim 11 , wherein the received measurement object contains an information element to configure cell global identifier reporting.
13. The user equipment of claim 11 , wherein the received measurement object contains an explicit indication for a frequency for reporting the cell global identifier.
14. The user equipment of claim 13 , wherein the explicit indication is a field within an information element for the received measurement object.
15. The user equipment of claim 14 , wherein the explicit indication is an index value.
16. The user equipment of claim 11 , wherein the received measurement object contains an implicit indication for a frequency for reporting the cell global identifier.
17. The user equipment of claim 16 , wherein the implicit indication uses an ordering of frequencies within the measurement object.
18. The user equipment of claim 17 , wherein the implicit indication is a frequency at a start of a list of frequencies.
19. The user equipment of claim 16 , wherein the implicit indication is a starting frequency value.
20. The user equipment of claim 11 , further comprising receiving a new measurement identifier and reporting configuration for reporting the cell global identifier from the network element.
