Transmission by a first node may be controlled based on a status of a second node. The status of the second node may indicate, for example, whether the second node will be communicating with the first node. Thus, if it is determined based on the status of the second node that the second node may not be communicating with the first node, transmissions by the first node may be temporarily disabled until there is a change in status, and vice versa.

Control of wireless transmission based on node status

Systems, apparatus and methods for facilitating identification and/or acquisition of an access point are provided. Methods can include transmitting or receiving access point information ('API') indicative of an identification of the access point ('AP'). The API can be provided at the AP through hardwiring or receipt of configuration information input by a user or transmitted to the AP by a network operator through Over-The-Air (&#x201c;OTA&#x201d;) signaling. The API can be computer-readable and, in some embodiments, the API can also be human-readable. The API can be transmitted on a paging channel from which user equipment (&#x201c;UE&#x201d;) can receive information. The frequency at which the API is transmitted can be fixed, dynamic and/or configurable. Upon receipt of the API, acquisition of the AP is attempted if the AP is determined to be a permitted AP.

Systems, methods and apparatus to facilitate identification and acquisition of access points

Efficient frequency assignment for mobile terminals in coexisting wireless communication systems is described herein. The coexisting wireless communication systems comprise a macro communication system and a localized communication system. Two prioritized lists are defined, a first list comprising a first entry relating to the macro communication system and the second entry relating to the localized communication system, the first and second entries each listing at least one common frequency. Based on the first list, a mobile terminal uses communication protocols associated with the localized communication system.

Efficient frequency assignment for mobile devices in coexisting wireless communication systems

Provisioning and access control for communication nodes involves assigning identifiers to sets of nodes where the identifiers may be used to control access to restricted access nodes that provide certain services only to certain defined sets of nodes. In some aspects provisioning a node may involve providing a unique identifier for sets of one or more nodes such as restricted access points and access terminals that are authorized to receive service from the restricted access points. Access control may be provided by operation of a restricted access point and/or a network node. In some aspects, provisioning a node involves providing a preferred roaming list for the node. In some aspects, a node may be provisioned with a preferred roaming list through the use of a bootstrap beacon.

Access terminal configuration and access control

Systems and methodologies are described that facilitate communicating PSC split information regarding neighboring cells. The PSC split information can be transmitted in one or more overhead messages selected based on network deployment. Where macro cells and femto cells provide PSC split information, which can be a PSC range for related cells, PSC list, etc., the information can be transmitted in a low priority overhead message since it can be obtained at a source cell. Where only femto cells or closed subscriber group (CSG) cells provide PSC split information, the information can be transmitted in a higher priority more frequently transmitted message. In this regard, the information is available at target cells since not all devices can access CSG cells. Thus, by providing the PSC split information in a more frequently transmitted message, devices can retrieve the PSC split information early on in communications to lower power consumption.

Optimized signaling of primary scrambling codes and frequency lists in wireless communications

Systems and methodologies are described that facilitate providing neighbor lists to devices comprising pilot frequencies of access points in a specific geographic region. Using the neighbor list, the devices can discover the access points based on scanning the frequencies for the pilot and can determine additional communication parameters from the discovery or based on a subsequent request resulting from discovery. In this regard, access point information need not be provisioned to the devices for locating the access points, selecting/reselecting the access points, providing the access points in a list to an interface, locating the device using triangulation based on GPS position of the access points, and/or the like.

Cell selection using enhanced general neighbor list methods

In a handover operation an access terminal is handed over from a source access point to a target access point. To facilitate efficient identification of a target access point, a handover operation may be initiated by the target access point. A candidate frequency search also may be invoked to confirm that an access terminal identified by a target access point for a handover is in the vicinity of the target access point. A source access point may verify whether an access terminal is in a vicinity of a target access point to determine whether to perform a handover operation. A source access point may handle potential ambiguity between several target access points by sending handover commands to each of these target access points. An access terminal also may assist in the determination of whether to perform a handover operation.

Target access point initiated communication handover

A method for allowing multiple devices to communicate includes initiating a multi-media communication session between a first device and a second device, each of the first and second device having access to at least one additional device, identifying at least a portion of the multi-media communication session to direct to the at least one additional device, the first device obtaining a unique identifier of the at least one additional device and directing the identified at least a portion of the multi-media communication session to the at least one additional device.

System and method for allowing multiple devices to communicate in a network

A femto cell neighbor list message for a wireless communication system that includes the frequencies and pseudonoise offsets reserved for macro cells and femto cells is disclosed. When the user equipment discovers the femto cell, the user equipment can read the Femto Cell Identification Message and present the identification information to the subscriber. In absence of this knowledge, a manual femto cell search must search all frequencies and all pseudonoise offsets resulting in lengthy search times.

Method and apparatus for femto cell deployment using neighbor list messages and its use in femto cell system selection

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.

Registration and access control in femto cell deployments

A venue-cast system and method for providing and receiving venue level transmissions and services, including discovery of a venue specific transmission by receiving an overhead signal from a non-venue network, extracting information for receiving the venue specific transmission from the overhead signal, and tuning to receive the venue specific transmission based on the extracted information. The venue level transmission may be provided and received in a manner that does not prevent an access terminal from receiving a local area or wide area transmission.

Apparatus and methods of providing and receiving venue level transmissions and services

In an embodiment, a client device (CD) maintains a contact profile for a user of the CD, the contact profile including a universal identifier (UID) for the user and a list of devices and addresses at which the user of the CD can be contacted. The CD establishes a communication session with a remote CD (RCD) via a given contact address from the set of contact addresses for the RCD. The CD shares, in response to the communication session establishment, at least a portion of the contact profile to the RCD. The RCD generates and/or updates a given contact profile for the user of the CD that is maintained on the RCD based on the shared contact profile. The RCD can also share its profile with the CD in response to the communication session establishment, causing the CD to generate and/or update a contact profile for the RCD.

Exchanging a contact profile between client devices during a communication session

Providing for distributed access point management for access to a mobile network is described herein. By way of example, an interface application maintained at a Femto cell base station (BS) can facilitate initial power up and/or acquisition for a Femto user terminal (UT). Upon start-up, a bootstrap process is utilized by the Femto cell to provision the UT with an SDL establishing at least one BS as high priority within a particular geographic area (GEO). Thus, when the Femto UT is within the GEO, the UT is more likely to acquire, camp on and/or handoff to the preferred BS. When outside the GEO, a serving access point can provision the Femto UT OTA with a custom SDL suited to another GEO having a different high priority access point. By implementing access point management at distributed access points, expensive network equipment can be mitigated or avoided.

Distributed mobile access point acquisition

A method includes receiving, at a station, a first delivery traffic indication message (DTIM) assigned to a first delivery interval. The first DTIM is configured to indicate whether group-addressed traffic is scheduled for delivery during a beacon interval. The first delivery interval is larger than a second delivery interval associated with a second DTIM. The method further includes receiving the group-addressed traffic during the beacon interval.

Standby time improvements for stations in a wireless network

Systems and methodologies are described that facilitate cell search, selection, and reselection within a wireless communication network that includes a home node base station (home nodeB). A user equipment (UE) can detect a home nodeB and communicate such identification to a macro network that includes at least one node base station (nodeB). The detected home nodeB and nodeB can be hierarchically structured in order to prioritize connectivity with the home nodeB over the nodeB. Such prioritization can be implemented by broadcasting home nodeB parameters and macro nodeB parameters having identification information therewith.
