Problems solved by technology

However, due to the rather large number of femtocells, NBL size can be an issue in case of "hand-in" (base station to femtocell handover)

Embodiment Construction

[0033] The embodiments are described in detail below. However, it should be appreciated that the present invention may be applicable in a wide variety of circumstances. The specific embodiments discussed are merely specific examples of implementations of the invention, and do not limit the scope of the invention.

[0034] The embodiment of the present invention will be described in a CDMA wireless network, such as a CDMA2000 1x or 1xEV-DO compatible wireless network. However, the present invention is also applicable to other wireless networks, such as Time Division Multiple Access (TDMA), Frequency Division Multiple Access (FDMA) and wireless networks based on them. These wireless networks support handover, and the candidate handover objects are more than the number of handover objects contained in the entries of the neighbor cell list.

Abstract

System and method for providing connection handoffs from macrocell to femtocell in wireless networks. A method comprises determining a group identifier from a received pseudorandom number sequence, determining a list of access points from a plurality of access points, wherein the access points in the list of access points are all identified by a group identifier, transmitting a request for detecting an identifier of the communications device to each access point in the list of access points, receiving a positive acknowledgement from a locating access point in the list of access points, and locating the communications device in a coverage area of the locating access point. The acknowledgement indicates that the locating access point successfully detected the identifier.

Description

technical field [0001] The present invention relates generally to systems and methods for wireless networks, and more particularly to systems and methods for connection handover from macrocells to femtocells in wireless networks. Background technique [0002] A cellular mobile communication system usually consists of numerous base stations (BSs) scattered over a geographical service area. Each base station may include at least one antenna and a base transceiver system (BTS) for providing wireless service to mobile terminals (MS) in its service area. The BTSs may be connected to base station controllers (BSCs), where each BSC is connected to multiple BTSs. Through the Packet Control Function (PCF), the BSC can be connected to a Mobile Switching Center (MSC) or a Packet Data Serving Node (PDSN), depending on whether voice or packet-switched data services are provided. BTS, BSC and MSC or PCF / PDSN jointly form a wireless network to provide wireless services. [0003] Wireles...
