Data routing in a universal mobile telecommunication system
First Claim
1. A method comprising:
- ascertaining that a first mobile equipment unit and a second mobile equipment unit are coupled to a common mobile communication switching network having a controller and coupled to a core network; and
transferring data between said first and said second mobile equipment units via the controller without transferring said data through the core network.

Abstract
A data routing methodology where part of the data routing functionality is moved from a core network (CN) to a UTRAN (UMTS Terrestrial Radio Access Network) in a UMTS (Universal Mobile Telecommunication System) system when the communicating source and destination mobile equipments (ME) are residing inside that UMTS system. The separation of user data and signaling flows in such a situation decreases the load of the Iu interface between the UTRAN and the CN, thus decreasing the probability of congestion on this interface and resulting in availability of more Iu bandwidth. The signaling flow is still handled by the CN via the Iu interface, however the data flow is handled by the UTRAN via its internal Iur interface.

7. A mobile communication system comprising:
-
a switching network configured to determine whether a first mobile equipment unit and a second mobile equipment unit are coupled to said mobile communication system and to generate an indication when said first and said second mobile equipment units are coupled to said mobile communication system; and a core network configured to receive said indication from said switching network and to responsively transfer data between said first and said second mobile equipment units via a first interface without transferring said data via a second interface, wherein said core network is configured to connect said first and said second mobile equipment units to said switching network and wherein said first interface is present only inside said core network, and wherein said second interface is present between said core network and said switching network. - View Dependent Claims (8, 9, 10, 11, 12)

13. A switching network for a mobile communication system, configured to:
-
determine whether a first mobile equipment unit and a second mobile equipment unit are located inside said mobile communication system; and instruct an access network configured to connect said first and said second mobile equipment units to said switching network in said mobile communication system to transfer data between said first and said second mobile equipment units via a first interface coupled to said access network without transferring said data via a second interface coupled between said access network and said switching network when said first and said second mobile equipment units are co-located in said switching network. - View Dependent Claims (14)

15. An access network for a mobile communication system, configured to connect a first mobile equipment unit and a second mobile equipment unit in said mobile communication system to a switching network, said access network configured to:
-
transfer data between said first and said second mobile equipment units via a first interface present only inside said access network, without transferring said data via a second interface present between said access network and said switching network; and further transfer non-data signaling information between any of said first and said second mobile equipment units and said switching network via said second interface without transferring said non-data signaling information via said first interface. - View Dependent Claims (16)

17. A computer readable data storage medium having stored thereon computer executed instructions which, when executed by one or more processors, cause said one or more processors to collectively perform the following:
-
configure a switching network in a mobile communication system to ascertain that both of a first mobile equipment unit and a second mobile equipment unit are located inside said mobile communication system; and further configure an access network in said mobile communication system and coupled to said first and said second mobile equipment units and to said switching network to transfer data between said first and said second mobile equipment units via a first interface present only inside said access network without transferring said data via a second interface present between said access network and said switching network after co-location of said first and said second mobile equipment units is ascertained by said switching network. - View Dependent Claims (18, 19, 20)
