摘要： According to some wireless network standards the size of a neighbor cell list is restricted to a maximum size. The limited size of a neighbor cell list may not reflect the realities of a wireless network deployment, especially for deployments including numerous femto cells clustered in close proximity. Accordingly, as the concentration of macro cells and/or femto cells in an area increases, there lies a challenge to identify and communicate neighbor lists to user devices that reflect the arrangement of a particular portion of the deployment and the needs of the user devices. Various systems, methods and apparatus described herein are configured to provide a user device or a group of user devices a neighbor cell list that includes neighbor cell identifiers chosen from a candidate list.

摘要： Aspects are disclosed for facilitating a hand-in to a femto cell. An identifier is assigned to a femto cell in which the identifier is based on a scrambling parameter and a timing parameter. A relationship between the identifier and the femto cell is then communicated. In another embodiment, a user equipment report is received, which includes attributes related to a signal broadcast by a femto cell. An identifier associated with the femto cell is ascertained from an attribute included in the report. The femto cell is then identified based on the identifier. In a further embodiment, a timing parameter is received, and a scrambling parameter is set. A signal including the scrambling parameter is then broadcast according to an offset related to the timing parameter. In yet another embodiment, a femto cell is detected during an active call. An identifier associated with the femto cell is then ascertained and reported.

摘要： Systems, methods, and devices are described for supporting macrocell-to-femtocell hand-ins of active macro communications for mobile devices. An out-of-band (OOB) link is used to detect that a mobile device is in proximity of a femtocell. Having detected the mobile device in proximity to the femtocell, an OOB proximity detection is communicated to a femtocell gateway disposed in a core network in communication with the macro network to effectively pre-register the mobile device with the femto-convergence system. When the femtocell gateway receives a handover request from the macro network implicating the pre-registered mobile device, it is able to reliably determine the appropriate target femtocell to use for the hand-in according to the pre-registration, even where identification of the appropriate target femtocell would otherwise be unreliable. Some embodiments may also handling registering the mobile device after a handover request has occurred, including tiered approaches.

摘要： A method for introducing hysteresis into a hard handoff decision in code division multiple access (CDMA) communications following an initial hard handoff is provided. The method introduces hysteresis when it is determined that the communicating mobile station system clock is slewing. The slewing determination follows from a calculation of the rate of change in the round trip delay (RTD) in communications with the mobile station. A calculated RTD rate of change is compared with a RTD slewing threshold, where the RTD threshold is the assumed slew rate of the mobile station. Hard handoffs are suspended as long as the calculated RTD rate of change exceeds the RTD slewing threshold. A system and apparatus to implement the above-described method are also provided.

摘要： Systems and methodologies are described that facilitate distributing and/or utilizing a Closed Subscriber Group (CSG) Identifier (ID) that identifies a CSG corresponding to a base station and a CSG indication that distinguishes between the base station permitting access to members of the CSG and permitting access to members and non-members of the CSG. For instance, the CSG ID can uniquely identify the CSG corresponding to the base station. A mobile device can receive the CSG ID and the CSG indication from the base station. Further, the received CSG ID can be compared to CSG IDs included in an allowed CSG list to recognize whether the mobile device is a member or a non-member of the CSG. Moreover, a preference for selecting the base station as compared to a disparate base station can be generated as a function of the received CSG ID and CSG indication.
