1. A method for accessing a multi-layer network, comprising:
- associating an advanced mobile station (AMS) with a first advanced base station (ABS) in the multi-layer network;
receiving a neighbor advertisement message, wherein the neighbor advertisement message lists ABSs according to a priority and according to an ABS type;
identifying ABSs in the neighbor advertisement message that are associated with the AMS, wherein the AMS is a member of a closed subscriber group (CSG) for ABSs configured to associate with the AMS;
locating a non-macro ABS from the neighbor advertisement message;
identifying whether the non-macro ABS is a CSG Closed Femto or a CSG Open Femto; and
handing over from the first ABS to the non-macro ABS based on at least one of a channel parameter and loading conditions.

7. A method for accessing a multi-layer network, comprising:
-
initializing an advanced mobile station (AMS) in the multi-layer network; determining if the AMS is a member of a closed subscriber group (CSG); scanning a first radio frequency (RF) carrier and a first RF carrier preamble to locate a CSG Closed Femto advanced base station (ABS) that provides service to a CSG Closed Femtocell; locating the CSG Closed Femto ABS; determining if the CSG Closed Femto ABS provides service to the AMS; locating a preferred channel list for the AMS, wherein the preferred channel list identifies one or more additional CSG Closed Femto ABSs associated with the AMS, wherein the additional CSG Closed Femto ABSs provide service to additional CSG Closed Femto cells; identifying a second RF carrier on the preferred channel list; and accessing the multi-layer network through the CSG Closed Femtocell or at least one of the additional CSG Closed Femto cells. - View Dependent Claims (8, 9, 10, 11)

12. A method for accessing a multi-layer network using an advanced mobile station (AMS), comprising:
-
receiving a superframe from a base station comprising a primary advanced preamble (PA-Preamble) and a secondary advanced preamble (SA-preamble); reading the SA-preamble of the superframe to identify hard partitions in the SA-preamble, wherein the hard partitions indicate the base station is a macro advanced base station (ABS) or a non-macro ABS; determining that the SA-preamble is from the non-macro ABS; reading the superframe to locate a superframe header (SFH), wherein the SFH identifies the non-macro ABS by partition as a closed subscriber group (CSG) Femto ABS; determining whether the AMS is a member of the CSG Femto ABS, wherein a list of CSG Femto base stations is provisioned in the AMS; associating with the CSG Femto ABS if the AMS is a member of the CSG Femto ABS; and associating with another ABS if the AMS is not a member of the CSG Femto ABS. - View Dependent Claims (13, 14, 15, 16, 17)

18. An article comprising a storage medium having stored thereon instructions that, when executed by a computing platform, results in:
-
associating an advanced mobile station (AMS) with a first advanced base station (ABS); receiving a neighbor advertisement message, wherein the neighbor advertisement message lists ABSs according to a priority and according to ABS type; identifying ABSs in the neighbor advertisement message that are associated with the AMS, wherein the AMS is a member of a closed subscriber group (CSG) for ABSs that are associate with the AMS; locating a non-macro ABS from the neighbor advertisement message; identifying whether the non-macro ABS is a CSG Closed Femto or a CSG Open Femto; and handing over from the first ABS to a second ABS based on at least one of a channel parameter and loading conditions. - View Dependent Claims (19, 20)
