Priority handling for data flow transport in communication systems
First Claim
1. A system for priority handling, the system comprising:
- a Policy and Charging Rules Function (PCRF) comprising a receiver, a transmitter, and processing circuitry, wherein the PCRF is configured to;
process a received request message, the request message identifying a first call involving a wireless device and containing priority sharing information;
obtain the priority sharing information from the received request message, wherein the priority sharing information indicates whether or not the first call is allowed to share a priority with certain other calls involving the wireless device, wherein the first call and each said other call has an Allocation and Retention Priority (ARP) value;
determine that the priority sharing information indicates that the first call is allowed to share a priority with said other calls;
as a result of determining that the priority sharing information indicates that the first call is allowed to share a priority with said other calls, then, for the first call and each said other call, identify the call'"'"'s ARP value;
determine, among said identified ARP values, the lowest identified ARP value; and
enable the first call and each said other call to share an Evolved Packet System (EPS) bearer by, for each call having an ARP value greater than the lowest identified ARP value, modifying the ARP value for the call so that the modified ARP value is the same as the lowest identified ARP value.

Abstract
A system, method, and network node for priority handling in a communications system are presented. The system comprises one or more data bearers and a priority handling module. Each of the one or more bearers is configured to transport one or more of the data flows. The priority handling module is configured to prioritize between data flows, and is further configured to: receive a request for priority configuration or re-configuration of a first data flow; obtain a priority sharing identifier of the first data flow; identify other data flows in the communication system having the priority sharing identifier of the first transport data flow; and update priority rules associated with the first data flow and also with any other identified data flows in the communication system having the priority sharing identifier of the first transport data flow to agree with a shared priority rule.

6. A method in a communication network, the method comprising:
-
a priority handling module receiving a request message, the request message identifying a first call involving a wireless device and containing priority sharing information; obtaining the priority sharing information from the received request message, wherein the priority sharing information indicates whether or not the first call is allowed to share a priority with certain other calls involving the wireless device, wherein the first call and each said other call has an Allocation and Retention Priority (ARP) value; determining that the priority sharing information indicates that the first call is allowed to share a priority with said other calls; as a result of determining that the priority sharing information indicates that the first call is allowed to share a priority with said other calls, then, for the first call and each said other call, identifying the call'"'"'s ARP value; determining, among said identified ARP values, the lowest identified ARP value; and enabling the first call and each said other call to share an Evolved Packet System (EPS) bearer by, for each call having an ARP value greater than the lowest identified ARP value, modifying the ARP value for the call so that the modified ARP value is the same as the lowest identified ARP value. - View Dependent Claims (7, 8, 9, 10, 11, 12, 13, 14)

15. A network node configured to perform priority handling in a communication network, the network node comprising:
-
a receiver for receiving a request message, the request message identifying a first call involving a wireless device and containing priority sharing information; and a processor configured to; obtain the priority sharing information from the received request message, wherein the priority sharing information indicates whether or not the first call is allowed to share a priority with certain other calls involving the wireless device, wherein the first call and each said other call has an Allocation and Retention Priority (ARP) value; determine that the priority sharing information indicates that the first call is allowed to share a priority with said other calls; as a result of determining that the priority sharing information indicates that the first call is allowed to share a priority with said other calls, then, for the first call and each said other call, identify the call'"'"'s ARP value; determine, among said identified ARP values, the lowest identified ARP value; and enable the first call and each said other call to share an Evolved Packet System (EPS) bearer by, for each call having an ARP value greater than the lowest identified ARP value, modifying the ARP value for the call so that the modified ARP value is the same as the lowest identified ARP value. - View Dependent Claims (16, 17, 18, 19)
