Method for handling attach reject message with #14 cause at user equipment
First Claim
1. A method for handling an ATTACH reject message with packet radio service mobility management reject cause number 14 (#14 cause) at a user equipment (UE), the method comprising:
- receiving, at the UE, an ATTACH accept message for a network service on a public land mobile network (PLMN) from a first network entity if a non-access stratum (NAS) timer is expired, wherein the PLMN is in a “
forbidden PLMNs for general packet radio service (GPRS) service”
list;
detecting, by the UE, that the UE'"'"'s evolved universal terrestrial radio access (E-UTRA) capability is disabled; and
enabling, by the UE, the UE'"'"'s E-UTRA capability and removing the PLMN from the “
forbidden PLMNs for GPRS service”
list.

Abstract
A method for handling an ATTACH reject message with packet radio service mobility management reject cause number (#14 cause) at a user equipment (UE) is provided. The method includes receiving, at the UE, an ATTACH accept message for a network service on a public land mobile network (PLMN) from a first network entity, wherein the PLMN is in a “forbidden PLMNs for general packet radio service (GPRS) service” list, detecting, by the UE, that the UE'"'"'s evolved universal terrestrial radio access (E-UTRA) capability is disabled, and enabling, by the UE, the UE'"'"'s E-UTRA capability and removing the PLMN from the “forbidden PLMNs for GPRS service” list.

5. A method for handling an ATTACH reject message with packet radio service mobility management reject cause number 14 (#14 cause) at a user equipment (UE), the method comprising:
-
sending, by the UE, an ATTACH request message for a circuit switched (CS) service and a packet switched (PS) service on a public land mobile network (PLMN) to a network entity, wherein the PLMN is in a “
selector PLMN”
list;receiving, by the UE, an ATTACH reject message with #14 cause from the network entity; and remaining, by the UE, camped on the network entity for the CS service and blocking PLMN selection when a “
user preferred PLMN”
list and an “
operator PLMN”
list are unavailable in a subscriber identity module (SIM) of the UE. - View Dependent Claims (6)

7. A user equipment (UE) for handling an ATTACH reject message with packet radio service mobility management reject cause number 14 (#14 cause), comprising:
-
a controller configured to; receive an ATTACH accept message for a network service on a public land mobile (PLMN) from a first network entity if a non-access stratum (NAS) timer is expired, wherein the PLMN is in a “
forbidden PLMNs for general packet radio service (GPRS) service”
list;detect that the UE'"'"'s evolved universal terrestrial radio access (E-UTRA) capability is disabled; and enable the UE'"'"'s E-UTRA capability and remove the PLMN from the “
forbidden PLMNs for GPRS service”
list. - View Dependent Claims (8, 9, 10)

13. A non-transitory computer-readable storage medium having recorded thereon a computer program for executing a method of:
-
receiving, at a user equipment (UE), an ATTACH accept message for a network service on a public land mobile network (PLMN) from a first network entity if a non-access stratum (NAS) timer is expired, wherein the PLMN is in a “
forbidden PLMNs for general packet radio service (GPRS)”
list;detecting, by the UE, that the UE'"'"'s evolved universal terrestrial radio access (E-UTRA) capability is disabled; and enabling, by the UE, the UE'"'"'s E-UTRA capability and removing the PLMN from the “

14. A non-transitory computer-readable storage medium, having recorded thereon a computer program for executing a method of:
-
sending, by a user equipment (UE), an ATTACH request message for a circuit switched (CS) service and a packet switched (PS) service on a public land mobile network (PLMN) to a network entity, wherein the PLMN is in a “
selector PLMN”
list;receiving, by the UE, an ATTACH reject message with general packet radio service (GPRS) mobility management (GMM) reject cause number 14 (#14 cause) from the network entity; and remaining, by the UE, camped on the network entity for the CS service and blocking PLMN selection when a “
user preferred PLMN”
list and an “
operator PLMN”
list are unavailable in a subscriber identity module (SIM) of the UE.
