A trend that began about a decade ago for telecommunications network operators has accelerated in recent years. This trend, to outsource infrastructure as well as certain operational support to third party managed communications providers, is reaching a next stage in evolution. Historically, telecom operators have looked to service bureau providers for intermediation services, database services, and various OSS/BSS support. The more recent trend has been to outsource infrastructure as a service as a means of reducing Capital Expenditure (CapEx) and to use as negotiation leverage for improved pricing on next generation networks such as IP Multimedia Subsystem (IMS) and LTE infrastructure such as Voice over LTE (VoLTE).
