Error reporting in a mobile telecommunications network
First Claim
1. A method of reporting errors in a mobile telecommunications network having a core network and a UTMS Terrestrial Radio Access Network (UTRAN), the method comprising:
- generating an error message at an error originating entity in one of the core network and the UTRAN;
sending the error message to an error destination entity in the other of the core network and the UTRAN over an Iu interface; and
at each intermediate entity through which the error message passes, incrementing a distance counter contained in or accompanying the error message, wherein the error destination entity is able to identify the error originating entity on the basis of the value of the distance counter contained in or accompanying the received error message.

Abstract
A method of reporting errors in a mobile telecommunications network comprising a core network and a UMTS Terrestrial Radio Access Network (UTRAN). The method comprises the steps of generating an error message at an error originating entity in either the core network or the UTRAN, sending the error message to an error destination entity in the other of the core network and the UTRAN over an Iu interface, and incrementing a distance counter contained in or accompanying the error message at each intermediate entity through which the error message passes. The error destination entity is able to identify the error originating entity on the basis of the value of the distance counter contained in or accompanying the received error message.

10. A mobile telecommunications network comprising a core network and a UMTS Terrestrial Radio Access Network (UTRAN) each comprising a number of nodes communicating over an Iu interface with nodes of the other network, wherein each node comprises:
-
means for generating error messages at an error originating entity;
means for sending error messages to an error destination entity in another node, and means for receiving error messages from an error generating entity in another entity, over an Iu interface; and
at least one intermediate entity through which error messages pass and which are arranged to increment a distance counter contained in or accompanying each error message, wherein an error destination entity is able to identify the error originating entity on the basis of the value of the distance counter contained in or accompanying the received error message.

11. A method of reporting errors in a mobile telecommunications network having a core network and a UMTS Terrestrial Radio Access Network (UTRAN), the method comprising:
-
generating an error message at an error originating entity in one of the core network and the UTRAN;
constructing an abnormal event frame incorporating the error message and a code which identifies the location of the error originating entity; and
sending the error message to an error destination entity in the other of the core network and the UTRAN over an Iu interface, wherein the error destination entity is able to identify the location of the error originating entity on the basis of the code contained in the abnormal event frame. - View Dependent Claims (12)
