Abstract
Bandwidth for a radio access network may be efficiently allocated for certain voice over LTE (VoLTE) services. In one implementation, a request associated with traffic flows may be received. Each of the traffic flows may be associated with an amount of guaranteed bit rate (GBR) traffic. The method may further include selectively summing the GBR traffic, to obtain an aggregate bandwidth value. The method may further include reserving an amount of GBR bandwidth corresponding to the previous version of the aggregate bandwidth value when a comparison indicates that the aggregate bandwidth value is less than the previous version of the aggregate bandwidth value; and reservation an amount of GBR bandwidth corresponding to the aggregate bandwidth value when a comparison indicates that the aggregate bandwidth value is not less than the previous version of the aggregate bandwidth value.
