Abstract
A method and apparatus are provided for controlling network access based on UE capability and subscription information. A method of a Mobility Management Entity (MME) includes receiving, from a User Equipment (UE), a message including voice domain preference information indicating whether the UE prefers an access network for a voice service; determining whether access of the UE to the mobile communication system is allowed based on the voice domain preference information; and transmitting, to the UE, a message indicating whether the access to the mobile communication system is allowed.
Claims14
A method of a Mobility Management Entity (MME) in a mobile communication system, the method comprising:
- receiving, at the MME, from a User Equipment (UE), a message including voice domain preference information indicating an access network that is preferred by the UE for a voice service;
- determining, by the MME, whether a user of the UE is a Voice over Long Term Evolution (VoLTE) subscriber;
- determining, by the MME, whether access of the UE to the mobile communication system is allowed based on the voice domain preference information and whether the user is a VoLTE subscriber;
- and
- transmitting, to the UE, a message indicating whether the access to the mobile communication system is allowed,
- wherein access to the mobile communication system is allowed if the voice domain preference information indicates that only VoLTE is supported by the UE and if the user of the UE is the VoLTE subscriber.
A Mobility Management Entity (MME) for use in a mobile communication system, the MME comprising:
- a transceiver configured to communicate with another network entity;
- and
- a controller configured to control the transceiver to receive, from a User Equipment (UE), a message including voice domain preference information indicating an access network that is preferred by the UE for a voice service, to determine whether a user of the UE is a Voice over Long Term Evolution (VoLTE) subscriber, to determine whether access of the UE to the mobile communication system is allowed based on the voice domain preference information and whether the user is a VoLTE subscriber, and to control the transceiver to transmit, to the UE, a message indicating whether the access of the UE to the mobile communication system is allowed,
- wherein access to the mobile communication system is allowed if the voice domain preference information indicates that only VoLTE is supported by the UE and if the user of the UE is the VoLTE subscriber.
