Abstract
In a wireless communication system, an IOPS-capable user equipment is registered on both a normal PLMN and an IOPS PLMN. The user equipment is configured to set one of the first PLMN and the second PLMN as a primary PLMN and the other one of the first PLMN and the second PLMN as a secondary PLMN randomly, according to an MO PLMN preference provided by a user of the user equipment, or according to a dialing history of the user equipment. Therefore, PLMN precedence can be provided for the user equipment in the IOPS dual PLMN mode of operation to make MO calls.
Claims9
A method of making a mobile-originated (MO) call using a user equipment in an isolated evolved universal terrestrial radio access network (E-UTRAN) operations for public safety (IOPS) dual public land mobile network (PLMN) mode of operation, the method comprising:
- the user equipment registering on both a first PLMN and a second PLMN, wherein the first PLMN is connected to a macro evolved packet core (EPC) and the second PLMN is isolated from the macro EPC;
- the user equipment setting one of the first PLMN and the second PLMN as a primary PLMN and an other one of the first PLMN and the second PLMN as a secondary PLMN randomly, according to a PLMN preference provided by a user of the user equipment, or according to a dialing history of the user equipment;
- and
- the user equipment making a first communication attempt by dialing the MO call via the primary PLMN.
A method of making an MO call using a user equipment in an IOPS dual PLMN mode of operation, the method comprising:
- the user equipment registering on both a first PLMN using a first smartcard and a second PLMN using a second smartcard, wherein the first PLMN is connected to an EPC and the second PLMN is isolated from the macro EPC;
- and
- the user equipment making a first communication attempt by dialing an MO call via the first PLMN and making a second communication attempt by dialing the MO call via the second PLMN at a same time.
