## Abstract

A radio access network node (e.g., Base Station Subsystem, Evolved Node B) and method are described herein for indicating to a core network node (e.g., Serving GPRS Support Node, Mobility Management Entity, CIoT Serving Gateway Node) usage of exception reports by a mobile station. In addition, a core network node (e.g., Serving GPRS Support Node, Mobility Management Entity, CIoT Serving Gateway Node) and method are described herein for receiving an indication of usage of exception reports by a mobile station.

## Claims

### Claim 1

A radio access network (RAN) node configured to communicate with a mobile station and a core network (CN) node, the RAN node comprising:
a processor; and,
a memory that stores processor-executable instructions, wherein the processor interfaces with the memory to execute the processor-executable instructions, whereby the RAN node is operable to:
receive, from the mobile station, a channel request;
assign radio resources to the mobile station for transmission of data;
after assigning radio resources, receive, from the mobile station, data transmitted as an exception report on the assigned radio resources and an indication that the mobile station transmitted data as an exception report with high priority; and
transmit, to the CN node, the data transmitted by the mobile station as an exception report and the indication that the mobile station transmitted data as an exception report with high priority,
wherein the indication is transmitted, to the CN node, in an Exception Report Flag Information Element (IE) included in an Uplink (UL)—UNITDATA Protocol Data Unit (PDU) carrying a Logical Link Control (LLC) PDU transmitted by the mobile station, and wherein the LLC PDU was sent by the mobile station using an uplink Extended Coverage—Enhanced General Packet Radio Service (EC-EGPRS) Temporary Block Flow (TBF) established in response to an EC-EGPRS PACKET CHANNEL REQUEST message or an EC-EGPRS PACKET DOWNLINK Acknowledgement/Negative Acknowledgement (ACK/NACK) message including a channel request.

### Claim 2

A method in a radio access network (RAN) node configured to communicate with a mobile station and a core network (CN) node, the method comprising:
receiving, from the mobile station, a channel request;
assigning radio resources to the mobile station for transmission of data;
after assigning radio resources, receiving, from the mobile station, data transmitted as an exception report on the assigned radio resources and an indication that the mobile station transmitted data as an exception report with high priority; and
transmitting, to the CN node, the data transmitted by the mobile station as an exception report and the indication that the mobile station transmitted data as an exception report with high priority,
wherein the indication is transmitted, to the CN node, in an Exception Report Flag Information Element (IE) included in an Uplink (UL)—UNITDATA Protocol Data Unit (PDU) carrying a Logical Link Control (LLC) PDU transmitted by the mobile station, and wherein the LLC PDU was sent by the mobile station using an uplink Extended Coverage—Enhanced General Packet Radio Service (EC-EGPRS) Temporary Block Flow (TBF) established in response to an EC-EGPRS PACKET CHANNEL REQUEST message or an EC-EGPRS PACKET DOWNLINK Acknowledgement/Negative Acknowledgement (ACK/NACK) message including a channel request.

### Claim 3

A core network (CN) node configured to communicate with a radio access network (RAN) node and a mobile station, the CN node comprising:
a processor; and,
a memory that stores processor-executable instructions, wherein the processor interfaces with the memory to execute the processor-executable instructions, whereby the CN node is operable to:
receive, from the RAN node, data transmitted by the mobile station as an exception report and an indication that the mobile station transmitted data as an exception report with high priority; and
perform one or more actions in response to receiving the indication, wherein the one or more actions include one or more of enabling adjustment of Charging Data Records (CDRs) associated with the mobile station or transmitting the indication to another CN node to cause the another CN node to adjust the CDRs,
wherein the indication is received, from the RAN node, in an Exception Report Flag Information Element (IE) included in an Uplink (UL)—UNITDATA Protocol Data Unit (PDU) carrying a Logical Link Control (LLC) PDU transmitted by the mobile station, and wherein the LLC PDU was sent by the mobile station using an uplink Extended Coverage—Enhanced General Packet Radio Service (EC-EGPRS) Temporary Block Flow (TBF) established in response to an EC-EGPRS PACKET CHANNEL REQUEST message or an EC-EGPRS PACKET DOWNLINK Acknowledgement/Negative Acknowledgement (ACK/NACK) message including a channel request.

### Claim 4 (depends on 3)

The CN node of claim 3, wherein enabling adjustment of the CDRs associated with the mobile station includes using information about an amount of the data transmitted as the exception report with high priority to enable adjustment of CDRs associated with the mobile station according to an operator's policy or business agreements.

### Claim 5 (depends on 3)

The CN node of claim 3, wherein the CN node is configured to communicate with the RAN node and the mobile station in a network, and wherein the one or more actions further include triggering detachment of the mobile station from the network when usage of exception reports is prohibited.

### Claim 6 (depends on 3)

The CN node of claim 3, wherein the CN node is further configured to communicate with the another CN node, and wherein transmitting the indication to the another CN node is via GPRS Tunnelling Protocol (GTP).

### Claim 7 (depends on 6)

The CN node of claim 6, wherein transmission via GTP of the indication, to the another CN node, causes the another CN node to adjust the CDRs associated with the mobile station according to an operator's policy or business agreements.

### Claim 8 (depends on 6)

The CN node of claim 6, wherein transmission via GTP of the indication, to the another CN node, causes the another CN node to report the mobile station's usage of exception reporting to a Policy and Charging Control (PCC) architecture.

### Claim 9

A method in a core network (CN) node configured to communicate with a radio access network (RAN) node and a mobile station, the method comprising:
receiving, from the RAN node, data transmitted by the mobile station as an exception report and an indication that the mobile station transmitted data as an exception report with high priority; and
performing one or more actions in response to receiving the indication, wherein the one or more actions include one or more of enabling adjustment of Charging Data Records (CDRs) associated with the mobile station or transmitting the indication to another CN node to cause the another CN node to adjust the CDRs,
wherein the indication is received, from the RAN node, in an Exception Report Flag Information Element (IE) included in an Uplink (UL)—UNITDATA Protocol Data Unit (PDU) carrying a Logical Link Control (LLC) PDU transmitted by the mobile station, and wherein the LLC PDU was sent by the mobile station using an uplink Extended Coverage—Enhanced General Packet Radio Service (EC-EGPRS) Temporary Block Flow (TBF) established in response to an EC-EGPRS PACKET CHANNEL REQUEST message or an EC-EGPRS PACKET DOWNLINK Acknowledgement/Negative Acknowledgement (ACK/NACK) message including a channel request.
