An apparatus and method capable of creating and controlling voice bearer in reverse single radio voice call continuity comprise performing a handover request action Sof generating a request to a mobile management entity for a handover of a mobile communication call of a user equipment from circuit switched mobile communication to packet switched mobile communication in response to an indication of required handover Sby a radio access network controller entity; performing a notification action Sof notifying an access transfer control function to prepare for the transfer of media to packet switched mobile communication by allocating media ports on an access transfer gateway; and performing an obtaining action Sof obtaining the allocated media ports from the notified access transfer control function, wherein both the notification action Sand the obtaining action Sare performed after the indication of required handover Sis obtained from the radio access network controller entity and before the performing of the handover request action S, and information on the allocated media ports is included into the request Sto the mobile management entity.

Apparatus and method for selecting voice bearer in reverse single radio voice call continuity

In accordance with the exemplary embodiments of the invention there is a method, executable computer program, and apparatus for receiving information including at least one packet data protocol context of a target network, and based on the information, for mapping in a source network at least one bearer to the at least one packet data protocol context. In addition, in accordance with another exemplary embodiment of the invention there is a method, executable computer program, and apparatus for receiving from a source network device information comprising an indication of at least one bearer mapped to the at least one packet data protocol context of a target network, and storing the received information for use in a handover.

Mapping quality of service for intersystem handover

There is provided a radio system wherein a mobile terminal is configured to detect availability of a local breakout service to an Internet protocol gateway; to start a network entry to the local breakout service; and to configure an Internet protocol stack of the mobile terminal on the basis of received configuration data. A serving base station of the mobile terminal is configured to establish a radio bearer for the local breakout service; to provide a dynamic host control protocol relay function for mapping data of the mobile terminal using a local Internet protocol address to the established radio bearer; and to provide the local breakout service to the Internet protocol gateway while retaining user access control and a remote Internet protocol gateway of a packet core network of the public mobile network for the mobile terminal.

Method, radio system, mobile terminal and base station for providing local breakout service

An apparatus and a method are provided for multiplexing different sessions using the same authorized contexts for media. The method includes distinguishing different control plane sessions by a user equipment, and identifying media flows of a same application among the different control plane sessions by the user equipment by setting a service identifier. The method further includes sending the service identifier by the user equipment to a call state control function including a policy decision function, and authorizing quality of service for a user plane context by the policy decision function. Furthermore, the method includes enabling, by the policy decision function based on the service identifier, the different control plane sessions with media flows of the same application to share the same user plane context with the authorized quality of service to multiplex the different control plane sessions with media flows of the same application.

Multiplexing media components of different sessions

A method of multiplexing different sessions using the same authorized contexts for media, comprising: distinguishing the sessions to be multiplexed, by a device; creating a new session on a control plane; indicating media flows of different sessions; and enabling the sessions to share the same authorized context for media, thus being multiplexed.
