4 Advanced Network and Services Management (Self-Organizing Networks) One of the most important trends in the wireless communication industry is advancements in network management, and the accompanying management of services. The goal of these advancements is to make network configuration as automated as possible, ultimately to have the networks self-configure. Thus, the term Self-Organizing Networks (SON) Nowhere is the goal of SON more important than in the case of femto cell systems. From the operator’s perspective, the process (e.g., activations of femto cell systems), should be “no-touch,” with rare cases of manual intervention and trouble-shooting. Femto cell systems are the best application of SON. [Source: SC.R GPP2 Vision for 2010 and Beyond]

5 SON (2 OF 2) The operator requirements for efficient network management and operation amplify the need for Self-Organizing Networks (SON). SON improves the ability of network elements to communicate information between elements and allows self-configuration relative to the other elements in the network. This work includes both intra- CDMA and inter-RAT (Radio Access Technologies) SON communications. A multiple phase approach to the SON work in 3GPP2 is being pursued beginning with: –SON System Requirements (S.P0150-0) –CDMA-only Energy Saving (ES)-mode (A.S0010-0) –Inter-RAT ES-mode for LTE-eHRPD and LTE-eHRPD load balancing requirements (in conjunction with 3GPP) (S.P0150-0, A.S0010-A) [Sources: SC.R GPP2 Vision for 2010 and Beyond and WI 3GPP ]

6 Green Revised Energy Efficient Network (GREEN) In the current era of worldwide attention given to global warming and the drive toward cleaner and more efficient products and technologies, 3GPP2 is doing its part to address these issues by developing and refining standards to be conducive to GREEN technologies. Issues being addressed include: –Battery life considerations for access terminals –Power consumption by infrastructure functional elements –Better match of available power in both network and terminal equipment 3GPP2 developed a “Green Revised Energy Efficient Network (GREEN) – Technology Initiative Study for cdma2000 Wireless Networks” (S.R0140-0) [Source: SC.R GPP2 Vision for and Beyond]

7 Energy Savings (ES) Management is being addressed in A.S “cdma2000 RAN Management”. –Provides the protocols and procedures to support cdma2000 ®1 RAN Management in the Radio Access Network (RAN). –Describes a new RAN interface between CDMA RANs to allow RANs to notify each other when they are powering off resources, or when they need a resource powered on to handle load or emergency traffic. 1 cdma2000® is the trademark for the technical nomenclature for certain specifications and standards of the Organizational Partners (OPs) of 3GPP2.

8 Mobile Switching Center (MSC) Pool MSC Pool enables signaling between one Base Station Controller (BSC) with multiple MSCs. A Mobile Station (MS) served by a BSC can be served by any MSC in the pool area. The purpose of MSC Pool support is to: –Achieve load balance / re-distribution –Improve reliability with minimum change to the BSC and the MSC –Facilitate Core Network (CN) capacity expansion 3GPP2 published specifications include: –S.R System Requirements for MSC Pool –A.S Interoperability Specification (IOS) for MSC Pool Network This allows a more flexible network topology, so if an MSC or MSCe goes out of service, it does not cause an entire geographic area assigned to that node to be out of service.
