Configurable mapping of quality of service classes

Abstract

Various communication systems may benefit from improved quality of service treatment in the access networks. For example, certain communication systems may benefit from a dynamic varying of the quality of service level of a data flow. A method may include detecting a requested quality of service level requirement at a new data flow or an existing data flow at a network entity. The method may also include retrieving from a table a needed parameter linked to the requested quality of service level. In addition, the method can include using the needed parameter to create a new processing instance or to update an existing processing instance at the network entity. A method may further include updating the content of the table through separate signaling.

1 . A method, comprising:
 detecting a requested quality of service level of a new data flow or an existing data flow at a network entity;   retrieving from a table a needed parameter linked to the requested quality of service level; and   using the needed parameter to create a new processing instance or to update an existing processing instance at the network entity.   
     
     
         2 . The method according to  claim 1 , wherein the needed parameter is determined based on the table, wherein the table is configured to indicate the mapping between the quality of service and the needed parameter. 
     
     
         3 . The method according to  claim 1 , wherein the needed parameter is linked to the requested quality of service for a layer or a network service. 
     
     
         4 . The method according to  claim 1 , further comprising:
 receiving embedded in a data flow packet an indication of the requested quality of service level.   
     
     
         5 . The method according to  claim 1 , further comprising:
 receiving a control message from the network operator updating a parameter of the table.   
     
     
         6 . The method according to  claim 4 , wherein the data flow packet comprises a packet header with a triggering bit configured to indicate that a new or updated table should be taken into use. 
     
     
         7 . The method according to  claim 4 , wherein the data flow packet comprises a triggering packet configured to indicate that a new or updated table should be taken into use. 
     
     
         8 . The method according to  claim 1 , further comprising:
 receiving a data flow packet comprising a data identification configured to initiate the creating of the new processing instance.   
     
     
         9 . The method according to  claim 1 , further comprising:
 performing multi-connectivity routing using the table.   
     
     
         10 . A method, comprising:
 detecting a requested quality of service level of a new data flow or an existing data flow at a user equipment;   retrieving from a table, at the user equipment, a needed parameter linked to the requested quality of service level;   marking an uplink data packet using a quality of service marking as detected in a downlink data packet received by the user equipment; and   sending the uplink data packet to a network entity.   
     
     
         11 . The method according to  claim 10 , wherein the uplink data packet may trigger the creation of a new processing instance or an update of an existing processing instance in the network entity. 
     
     
         12 . The method according to  claim 10 , wherein the needed parameter is linked to the requested quality of service for a layer or a network service. 
     
     
         13 . The method according to  claim 10 , wherein the table is configured to indicate the mapping between the quality of service and the needed parameter. 
     
     
         14 . The method according to  claim 10 , further comprising:
 receiving a control message from the network operator updating a parameter of the table.   
     
     
         15 . The method according to  claim 10 , further comprising:
 updating the table through an subscribe identity module update message.   
     
     
         16 . The method according to  claim 10 , wherein the parameter comprises at least one of a priority class, maximum latency, minimum throughput, radio convergence sublayer service, reordering window, or maximum drop rate. 
     
     
         17 . The method according to  claim 10 , further comprising:
 receiving a change in a data flow packet quality of service marking to indicate that a new set of processing parameters should be retrieved from the table.   
     
     
         18 . The method according to  claim 10 , wherein the parameter is retrieved without control plane involvement. 
     
     
         19 . An apparatus comprising:
 at least one memory comprising computer program code;   at least one processor;   wherein the at least one memory and the computer program code are configured, with the at least one processor, to cause the apparatus at least to:   detect a requested quality of service level at a new data flow or an existing data flow at a network entity;   retrieve from a table a needed parameter linked to the requested quality of service level; and   use the needed parameter to create a new processing instance or to update an existing processing instance at the network entity.   
     
     
         20 . A non-transitory computer-readable medium encoding instructions that, when executed in hardware, perform a process according to  claim 1 .
