Abstract
In an access device associated with a first network cell, a method for enabling user equipment (UE) to obtain a service unavailable through the first network cell includes receiving a request for the UE to access the service, and identifying, in a message to the UE, a plurality of second network cells providing the service.

A method for enabling user equipment (UE) to obtain a service unavailable through a first network cell, the method comprising:
- transmitting, by a UE, a first message including a request for the UE to access the service, wherein the service is a circuit-switched (CS) service;
- and
- receiving, from the first network cell, a second message, wherein the second message identifies a plurality of second network cells providing the service, the second message includes system information of the plurality of second network cells, the system information identifies location areas of the plurality of second network cells, and the first network cell employs a different radio access technology (RAT) than the plurality of second network cells.
A method for enabling user equipment (UE) to obtain a service not available through a first network cell, the method comprising:
- connecting with an evolved Node B (eNB) associated with the first network cell in an evolved universal terrestrial radio access network (E-UTRAN);
- transmitting, by the UE, a first message including a request for the UE to access the service, wherein the service is a circuit-switched (CS) service;
- and
- receiving, from the eNB, a second message, wherein the second message identifies a plurality of second network cells providing the service, the second message includes system information of the plurality of second network cells, the system information identifies location areas of the plurality of second network cells, and the first network cell employs a different radio access technology (RAT) than the plurality of second network cells.
A user equipment (UE) to obtain a service unavailable through a first network cell, comprising:
- at least one hardware processor;
- a non-transitory computer-readable storage medium coupled to the at least one hardware processor and storing programming instructions for execution by the at least one hardware processor, wherein the programming instructions instruct the at least one hardware processor to:
- transmit a first message including a request for the UE to access the service, wherein the service is a circuit-switched (CS) service;
- and
- receive, from the first network cell, a second message, wherein the second message identifies a plurality of second network cells providing the service, the second message includes system information of the plurality of second network cells, the system information identifies location areas of the plurality of second network cells, and the first network cell employs a different radio access technology (RAT) than the plurality of second network cells.
A non-transitory computer readable medium for enabling user equipment (UE) to obtain a service unavailable through a first network cell, the computer readable medium storing instructions to cause a processor to perform operations comprising:
- transmitting, by a UE, a first message including a request for the UE to access the service, wherein the service is a circuit-switched (CS) service;
- and
- receiving, from the first network cell, a second message, wherein the second message identifies a plurality of second network cells providing the service, the second message includes system information of the plurality of second network cells, the system information identifies location areas of the plurality of second network cells, and the first network cell employs a different radio access technology (RAT) than the plurality of second network cells.
A non-transitory computer readable medium for enabling user equipment (UE) to obtain a service not available through a first network cell, the computer readable medium storing instructions to cause a processor to perform operations comprising:
- connecting with an evolved Node B (eNB) associated with the first network cell in an evolved universal terrestrial radio access network (E-UTRAN);
- transmitting, by the UE, a first message including a request for the UE to access the service, wherein the service is a circuit-switched (CS) service;
- and
- receiving, from the eNB, a second message, wherein the second message identifies a plurality of second network cells providing the service, the second message includes system information of the plurality of second network cells, the system information identifies location areas of the plurality of second network cells, and the first network cell employs a different radio access technology (RAT) than the plurality of second network cells.
A user equipment (UE) for enabling user equipment (UE) to obtain a service not available through a first network cell, comprising:
- at least one hardware processor;
- a non-transitory computer-readable storage medium coupled to the at least one hardware processor and storing programming instructions for execution by the at least one hardware processor, wherein the programming instructions instruct the at least one hardware processor to:
- connect with an evolved Node B (eNB) associated with the first network cell in an evolved universal terrestrial radio access network (E-UTRAN);
- transmit a first message including a request for the UE to access the service, wherein the service is a circuit-switched (CS) service;
- and
- receive, from the eNB, a second message, wherein the second message identifies a plurality of second network cells providing the service, the second message includes system information of the plurality of second network cells, the system information identifies location areas of the plurality of second network cells, and the first network cell employs a different radio access technology (RAT) than the plurality of second network cells.
