CELL SELECTION MANAGEMENT FOR END DEVICE IN FEMTOCELL COVERAGE AREA
First Claim
Patent Images
1. A method comprising:
- performing, by an end device, a cell selection procedure or a cell reselection procedure, wherein the end device is an Evolved Universal Terrestrial Radio Access-New Radio (E-UTRA-NR) Dual Connectivity (EN-DC) capable device;
reading, by the end device, a first system information block (SIB) message broadcasted by a first wireless station, wherein the first SIB message indicates that the first wireless station is at least one of a femtocell device or a non-EN-DC capable anchor device;
determining, by the end device, whether the first wireless station identified during the cell selection procedure or the cell reselection procedure is an EN-DC capable anchor device based on the first SIB message;
omitting to camp, by the end device in response to determining that the first wireless station is not the EN-DC capable anchor device, on the first wireless station; and
determining, by the end device in response to the omitting, whether a second candidate cell is available on which to camp.

Abstract
A method, a device, and a non-transitory storage medium are described in which cell selection management service is provided. An Evolved Universal Terrestrial Radio Access-New Radio (E-UTRA-NR) Dual Connectivity (EN-DC) capable end device uses a system information block message to determine whether a wireless station is an EN-DC capable anchor device. Also, the EN-DC capable end device may store a permanent tracking area forbidden list that includes tracking area identifiers pertaining to non-EN-DC capable anchor devices that include femtocell devices.

9. An end device comprising:
-
a radio communication interface; a memory, wherein the memory stores instructions; and a processor, wherein the processor executes the instructions to; perform a cell selection procedure or a cell reselection procedure, wherein the end device is an Evolved Universal Terrestrial Radio Access-New Radio (E-UTRA-NR) Dual Connectivity (EN-DC) capable device; read a first system information block (SIB) message broadcasted by a first wireless station, wherein the first SIB message indicates that the first wireless station is at least one of a femtocell device or a non-EN-DC capable anchor device; determine whether the first wireless station identified during the cell selection procedure or the cell reselection procedure is an EN-DC capable anchor device based on the first SIB message; omit to camp, in response to a determination that the first wireless station is not the EN-DC capable anchor device, on the first wireless station; and determine, in response to the omission to camp, whether a second candidate cell is available on which to camp. - View Dependent Claims (10, 11, 12, 13, 14, 15, 16)

17. A non-transitory computer-readable storage medium storing instructions executable by a processor of an end device, which when executed cause the end device to:
-
perform a cell selection procedure or a cell reselection procedure, wherein the end device is an Evolved Universal Terrestrial Radio Access-New Radio (E-UTRA-NR) Dual Connectivity (EN-DC) capable device; read a first system information block (SIB) message broadcasted by a first wireless station, wherein the first SIB message indicates that the first wireless station is at least one of a femtocell device or a non-EN-DC capable anchor device; determine whether the first wireless station identified during the cell selection procedure or the cell reselection procedure is an EN-DC capable anchor device based on the first SIB message; omitting to camp, in response to a determination that the first wireless station is not the EN-DC capable anchor device, on the first wireless station; and determine, in response to the omission to camp, whether a second candidate cell is available on which to camp. - View Dependent Claims (18, 19, 20)
