Abstract

Methods and computing systems for determining a committed information rate for a plurality of cell sites are described. Data associated with throughput of combined voice and data traffic communicated between a core network and the plurality of cellular sites is received. An oversubscription ratio for the committed information rate is determined based on a predetermined service outage threshold and a plurality of peak throughput values of the combined voice and data traffic over a plurality of time periods. An oversubscribed committed information rate for the plurality of cellular sites is determined based on the oversubscription ratio.

First claim

What is claimed is:

1 . A method of determining a committed information rate for a plurality of cell sites, the method comprising:
receiving data associated with throughput of combined voice and data traffic communicated between a core network and the plurality of cellular sites; determining, from a predetermined service outage threshold and a plurality of peak throughput values of the combined voice and data traffic over a plurality of time periods, an oversubscription ratio for the committed information rate; and initiating a provision of an oversubscribed committed information rate for the plurality of cellular sites based on the oversubscription ratio.

2 . The method of claim 1 , further comprising determining the oversubscription ratio based on a mean of the peak throughput values and a standard deviation of the peak throughput values of the combined voice and data traffic.

3 . The method of claim 1 , wherein the peak throughput values of the combined voice and data traffic over the plurality of time periods are one of weekly peak rates, daily peak rates, or hourly peak rates.

4 . The method of claim 1 , further comprising:
determining an initial committed information rate for the plurality of cellular sites based on peak throughputs for individual cellular sites of the plurality of cellular sites, wherein the data associated with the throughput of the combined voice and data traffic is from a time that the virtual circuit is provisioned at the initial committed information rate.

5 . The method of claim 1 , further comprising:
determining an increased committed information rate for the virtual circuit, the increased committed information rate determined based on a sum of the oversubscribed committed information rate and an observed peak throughput for a new cellular site being added to the plurality of cellular sites.

6 . The method of claim 5 , further comprising:
receiving further data, observed at a time that the virtual circuit is provisioned with the increased committed information rate, new throughput of combined voice and data traffic of the plurality of cellular sites including the new cellular site; and determining a new oversubscription committed information rate for the plurality of cellular sites based on new peak throughput values of the combined voice and data traffic of the plurality of cellular sites including the new cellular site.

7 . The method of claim 1 , further comprising:
determining an new temporary committed information rate for the plurality of cellular sites, the new temporary committed information rate determined based on a sum of the oversubscribed committed information rate and an observed increased throughput for an upgraded cellular site of the plurality of cellular sites.

8 . The method of claim 7 , further comprising:
receiving further data, observed at a time that the virtual circuit is provisioned with the new temporary committed information rate, new throughput of combined voice and data traffic of the plurality of cellular sites including the upgraded cellular site; and determining a new oversubscription committed information rate for the plurality of cellular sites based on new peak throughput values of the combined voice and data traffic of the plurality of cellular sites including the upgraded cellular site.

9 . A computing system, comprising:
one or more processors; memory; and one or more program modules stored on the memory and executable by the one or more processors to cause the computing system to:
receive data regarding throughput of combined voice and data traffic communicated via a virtual circuit between a plurality of mobile access sites and a core network; and
determine, based on peak throughput values of the combined voice and data traffic, and based on a predetermined performance threshold, an oversubscription metric for a committed information rate of the plurality of mobile access sites.

10 . The computing system of claim 9 , wherein the one or more program modules are further executable by the one or more processors to cause the computing system to determine the oversubscription metric based on a mean peak throughput value and a standard deviation of the peak throughput values of the combined voice and data traffic.

11 . The computing system of claim 9 , wherein the data regarding throughput of combined voice and data traffic was captured at a time that the virtual circuit is provisioned at an initial committed information rate.

12 . The computing device of claim 9 , wherein the one or more program modules are further executable by the one or more processors to cause the computing system to determine a temporary new committed information rate for the plurality of mobile access sites, the temporary new committed information rate determined based on the oversubscribed committed information rate and an observed throughput for one or more of a new mobile access site being added to the plurality of of mobile access sites or a changed one of the plurality of mobile access sites.

13 . The computing device of claim 12 , wherein the one or more program modules are further executable by the one or more processors to cause the computing device to:
determine a new oversubscription committed information rate for the plurality of mobile access sites based on observed new peak throughput values of the combined voice and data traffic of the plurality of mobile access sites communicated via the virtual circuit at a time that the virtual is provisioned with the temporary new committed information rate.

14 . The computing device of claim 9 , wherein the one or more program modules are further executable by the one or more processors to cause the computing device to:
determine an increased committed information rate for the plurality of mobile access sites, the increased committed information rate determined based on a sum of the oversubscribed committed information rate and an available or observed throughput for a new mobile access site being added to the plurality of mobile access sites.

15 . The computing device of claim 14 , wherein the one or more program modules are further executable by the one or more processors to cause the computing device to:
determine a new oversubscription committed information rate for the plurality of mobile access sites based on new peak throughput values of the combined voice and data traffic of the plurality of mobile access sites including the new mobile access site.

16 . A method comprising:
initiating provision of a virtual circuit over a backhaul network, the virtual circuit having an initial committed information rate, the virtual circuit terminating at a first user network interface (UNI) for a hub of a plurality of cellular sites and at a second UNI for a core network device; monitoring combined voice and data traffic communicated over the virtual circuit between the hub and the core network; determining an oversubscription factor for the plurality of cellular sites based at least on peak throughput values of the combined voice and data traffic over a plurality of time periods; and initiating provision of an oversubscribed committed information rate for the plurality of cellular sites based on the oversubscription factor.

17 . The method of claim 16 , wherein the initial committed information rate is based on a sum of committed information rates determined for each of the cellular sites within the plurality of cellular sites.

18 . The method of claim 16 , wherein the determining the oversubscription factor incl
