Problems solved by technology

However, if the femtocell is relocated, turned off, etc., the remembered proximity of the femtocell may become outdated and thus no longer valid
Furthermore, since the mobile device only stores proximity information for femtocells that have been visited previously, the mobile device may use significant resources in searching for and locating new femtocells
Furthermore, mobile devices may be configured to report such invalid proximity information to their associated networks that may negatively impact network capacity

Embodiment Construction

[0039] The following description is provided with reference to the drawings, wherein like reference numerals are used to refer to like elements throughout. While various details of one or more techniques are described in this application, other techniques are also possible. In some instances, well-known structures and devices are shown in block diagram form in order to facilitate describing various techniques.

[0040] Methods for updating proximity information associated with a femtocell or other entity in a wireless communication network are described in this application. The term "proximity information" is defined as any information that assists a mobile device in determining its proximity to a network cell. Proximity information may include, but is not limited to: SPS coordinates of femtocells, set of cell identifiers for macrocells across different carriers, medium access control (MAC) addresses, street addresses or latitude / latitude corresponding to femtocells Longitud...

Abstract

Techniques are described herein for updating proximity information associated with a femtocell in a wireless communication system. An example of a method described herein includes identifying a location within a wireless communication network, associating the location with a femtocell for which proximity information relating to position of the femtocell is maintained, performing at least one search for the femtocell, and updating the proximity information maintained for the femtocell based on results of the at least one search. Another example of a method described herein includes obtaining a report of proximity information relating to a femtocell, identifying one or more network devices for which the proximity information is relevant, and communicating proximity information update signaling to the one or more network devices.

Description

[0001] Cross References to Related Applications [0002] This application claims priority to U.S. Provisional Patent Application No. 61 / 334,934, filed May 14, 2010, entitled "METHOD ANDAPPARATUS THAT FACILITATES UPDATING PROXIMITY INFORMATION ASSOCIATED WITH ACCESS POINT BASE STATIONS," Attorney Docket No. 101634P1, It is hereby incorporated by reference in its entirety for all purposes. Background technique [0003] Wireless communication devices are used incredibly widely in today's society. For example, people use cellular phones, smart phones, personal digital assistants, laptop computers, pagers, tablet computers, etc. to send and receive data wirelessly from a myriad of locations. In addition, advances in wireless communication technology have greatly increased the versatility of today's wireless communication devices, enabling users to use a single, portable device to perform a wide variety of tasks that would normally require multiple devices or larger, non-portable ...
