4. 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: “3GPP2 Vision for 2010 and Beyond” (3GPP2 SC.R5003-0 v2.0)]

5. 5 Advanced Network and Services Management (Self-Organizing Networks) - continued The operator requirements for efficient network management and operation amplify the need for Self-Organizing Networks (SON). 3GPP2 initiated a Work Item on SON (3GPP2-00299) to improve the ability of network elements to automatically communication information between themselves that allows each element to configure itself 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: –CDMA-only Energy Saving (ES)-mode (A.S0010-0) – in V&V –SON System Requirements (S.P0150-0) – under development –Inter-RAT ES-mode for LTE-eHRPD and LTE-eHRPD load balancing requirements (in conjunction with 3GPP) (S.P0150-0) [Sources: “3GPP2 Vision for 2010 and Beyond” (3GPP2 SC.R5003-0 v2.0) and WI 3GPP2-00299]

6. 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 [Source: “3GPP2 Vision for 20010 and Beyond” (3GPP2 SC.R5003-0 v2.0)]

7. 7 Green Revised Energy Efficient Network (GREEN) - continued 3GPP2 conducted and published a “Green Revised Energy Efficient Network (GREEN) – Technology Initiative Study for cdma2000 Wireless Networks” (3GPP2 S.R0140-0 v2.0) One target scenario of the 3GPP2 GREEN Study was to look at opportunities to better match available power in both network and terminal equipment. Figure 3.1.1: Power Supply Arrangement

8. 8 Green Revised Energy Efficient Network (GREEN) - continued Other scenarios and targets of the 3GPP2 GREEN Study include: –Controlling Femtocells and Other Household Objects –Interface and System Enhancements to Support GREEN RF Carrier Control as Function of Demand –BS Power Consumption Considerations Controlling Femtocells –User Zone Registration (Control Plane Signaling) Approach –Application Signaling Approach –System Architecture Considerations And more …

9. 9 SON and GREEN Energy Savings (ES) Management is being addressed in 3GPP2 TSG-A in 3GPP2 A.S0010-0 “cdma2000 ® RAN Management”. Targeted for publication in April 2012. –This document provides the protocols and procedures to support cdma2000 ® RAN Management in the Radio Access Network (RAN). –This document describes a new RAN interface between CDMA RANs that will 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. cdma2000® is the trademark for the technical nomenclature for certain specifications and standards of the Organizational Partners (OPs) of 3GPP2. Geographically (and as of the date of publication), cdma2000® is a registered trademark of the Telecommunications Industry Association (TIA-USA) in the United States.

10. 10 Equipment Identity Register (EIR) 3GPP2 X.S0008, “MAP Support for the Mobile Equipment Identity (MEID)” specifies the MAP modification needed for support of the MEID includes interface support to the Equipment Identity Register (EIR). There are EIR interface messages to obtain the status of an MEID. This specification is currently undergoing some enhancements. Target publication in 2012. The MEID specifications are stable. MEID in EIR is covered in X.S0008. The specifications for MEID, support an EIR. However, the use of an EIR is an option of the operator.

11. 11 Mobile Switching Center (MSC) Pooling Mobile Switching Center (MSC) Pool enables signaling connections between one Base Station Controller (BSC) with multiple MSCs, so the Mobile Station (MS) served by any BSC of that Pool Area (PA) can be served by any MSC in that 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 –Easier Core Network (CN) capacity expansion 3GPP2 initiated a MSC Pool Work Item 3GPP2-00144-A 3GPP2 published specifications include: – “System Requirements for MSC Pool” (3GPP2 S.R0136-0 v2.0) in November 2009. –“Interoperability Specification (IOS) for MSC Pool Network” (3GPP2 A.S0018-0 v1.0) in December 2009 [Sources: WI 3GPP2-00144, “System Requirements for MSC Pool” (3GPP2 S.R0136-0 v2.0)]

12. 12 Mobile Switching Center (MSC) Pooling - continued The Serving Node Selection Function (SNSF) is the key functionality for the MSC Pool application. The main function of the SNSF is selecting a serving MSC within the MSC Pool for a given user, and routing the signaling between the MSC and the BSC. The MSC Pool feature uses per-user signaling connections between a BSC and any one MSC or MSCe within the MSC pool with the aid of SNSF. An MSC pool may contain either MSC(s) or MSCe(s), but not both MSC(s) and MSCe(s), within the same pool. This allows a more flexible network topology, so if an MSC or MSCe goes not of service, it does not cause an entire geographic area assigned to that node to be out of service. [Source: “System Requirements for MSC Pool” (3GPP2 S.R0136-0 v2.0)]

13. 13 Mobile Switching Center (MSC) Pooling - continued Two scenarios where a network operator may wish to apply MSC Pool. –Scenario 1: When a MS moves within the Pool Area, the serving MSC or MSCe need not change. Hence, the signaling traffic of re-registration could be reduced. –Scenario 2: The Core Network (CN) can be expanded easier and can be scaled between the radio network and core network. For example, the operator could expand CN capacity by only introducing a new MSC or MSCe without new BSC(s). Additionally, a side benefit is load balance. The MSC Pool feature is not intended to be supported between and amongst multiple operators. [Source: “System Requirements for MSC Pool” (3GPP2 S.R0136-0 v2.0)]
