Abstract
A communication system and a method for the same is disclosed. In the method a first type of communication services is provided for a station (1), wherein a first network entity (3) provides control operations for the provision of the communication service. A part of said control operations is then relayed from the first network entity (3) to a second network entity (4). Information is exchanged between the first and second network entities, said information associating with provision of a second type of communication services for the station. A communication service of said second type is provided for the station based on said information.
Claims37
A method comprising:
- providing a first type of communication services for a station, wherein a first network entity is configured to provide control operations for the provision of said communication services in a first radio access system;
- relaying a part of said control operations from the first network entity to a second network entity, wherein the second network entity is configured to provide control operations for provision of communication services in a second radio access system, the first and second radio access systems providing said first type of communication services;
- exchanging between the first and second network entities information that associates with the provision of a second type of communication services during intrasystem handover for the first type of communication services, wherein the second network entity is also configured for provision of control operations for provision of communication services in a third radio access system and wherein said information comprises channel type parameters for the second type of communication services;
- and
- providing, based on said information, said second type of communication services for the station in the third radio access system.
2 more elements
A system comprising:
- first and second communication units configured to provide a first type of bearers for a station;
- a third communication unit configured to provide a second type of bearers for the station;
- a first network entity configured to control the first communication unit;
- a second network entity configured to control the second and third communication units, wherein a part of the control functions by the first network entity that associate with the provision of the first type of bearers can be relayed to the second network entity;
- and
- an interface, between the first and second entities, configured to exchange, during intrasystem handover for the first type of bearers, information that associates with provision of the second type of bearers for the station, wherein said information comprises channel type parameters for the second type of communication services and the third communication unit is configured to provide said second type of bearers for the station based on said information.
3 more elements
An apparatus comprising:
- a provider configured to provide a first type of communication services for a station, wherein a first network entity is configured to provide control operations for the provision of said communication services in a first radio access system;
- a relaying unit configured to relay a part of said control operations from the first network entity to a second network entity, wherein the second network entity is configured to provide control operations for provision of communication services in a second radio access system, the first and second radio access systems providing said first type of communication services;
- an exchanging unit configured to exchange, between the first and second network entities, information that associates with the provision of a second type of communication services during intrasystem handover for the first type of communication services, wherein the second network entity is also configured for provision of control operations for provision of communication services in a third radio access system and wherein said information comprises channel type parameters for the second type of communication services;
- and
- a provider configured to provide, based on said information, said second type of communication services for the station in the third radio access system.
2 more elements
An apparatus comprising:
- providing means for providing a first type of communication services for a station, wherein a first network entity is configured to provide control operations for the provision of said communication services in a first radio access system;
- relaying means for relaying a part of said control operations from the first network entity to a second network entity, wherein the second network entity is configured to provide control operations for provision of communication services in a second radio access system, the first and second radio access systems providing said first type of communication services;
- exchanging means for exchanging, between the first and second network entities, information that associates with the provision of a second type of communication services during intrasystem handover for the first type of communication services, wherein the second network entity is also configured for provision of control operations for provision of communication services in a third radio access system and wherein said information comprises channel type parameters for the second type of communication services;
- and
- providing means for providing, based on said information, said second type of communication services for the station in the third radio access system.
