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 [Source: SC.R GPP2 Vision for and Beyond]

7 GREEN (2 OF 4) 3GPP2 developed a “Green Revised Energy Efficient Network (GREEN) – Technology Initiative Study for cdma2000 Wireless Networks” (S.R0140-0) One target scenario of the GREEN Study was to look at opportunities to better match available power in both network and terminal equipment. Power Supply Arrangement

8 GREEN (3 OF 4) Other scenarios and targets of the GREEN Study include: –Controlling Femtocells and Other Household Objects –Interface and System Enhancements to Support GREEN RF Carrier Control as Function of Demand Controlling Femtocells –And more …

9 Energy Savings (ES) Management is being addressed in A.S “cdma2000 ®1 RAN Management”. –Provides the protocols and procedures to support cdma2000 ® 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. Geographically (and as of the date of publication), cdma2000® is a registered trademark of the Telecommunications Industry Association (TIA-USA) in the United States. GREEN (4 OF 4)

10 Equipment Identity Register (EIR) The EIR is a database to store MEID values and status that can be optionally used by operators to: –Track stolen mobiles –Track malfunctioning mobiles –Track mobiles for any other reasons –Manage devices that do not have properly formatted or missing MEID values MEID in EIR is covered in X.S0008. X.S0008, “MAP Support for the Mobile Equipment Identity (MEID)” specifies the MAP modification needed for support of the MEID. It includes interface support to the EIR such as –Messages to obtain the status of an MEID, –Messages to optionally send the MEID of a mobile to an EIR. X.S0008 is currently undergoing some enhancements.

12 EIR ( 3 of 3) The MEID specifications are stable and support an EIR. –The EIR bridges the gap between the existing capabilities of ESN trackers and the rest of the core network. –EIR is critical for the ESN migration to MEID. The use of an EIR is an option of the operator. –EIR can be used to restrict, deny, or allow access to network services. –EIR supports operator future expansion, particularly in terms of number planning and mobile equipment identity. –EIR can support operator deployment of M2M based on MEID.

13 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.

15 MSC Pool (3 of 3) 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: S.R System Requirements for MSC Pool]
