Local IP access paging schemes facilitate paging of an access terminal when packets destined for the access terminal are received via local IP access. In some implementations, a local entity acquires information that enables local paging of the access terminal by sniffing messages passing through the local entity. In some implementations, a local entity sends a packet or message to cause the core network to page an access terminal when a local IP access packet destined for the access terminal arrives at the local entity.

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.

Techniques for supporting handoff of a terminal between base stations of different protocol revisions (P_REVs) in a CDMA system. One technique includes performing a handoff of the terminal from a first base station to a second base station. The handoff is performed while the terminal is in an active call using a first service configuration with the first base station. The first base station supports a first protocol revision and the second base station supports a second protocol revision that is later than the first protocol revision. A first message is sent indicative of a change in packet zone. A request is received to originate a new call with a second service configuration. The new call is maintained with the second service configuration between the terminal and the second base station.

Handoff between base stations of different protocol revisions in a CDMA system

Techniques for supporting handoff of a terminal between base stations of different protocol revisions (P_REVs) in a CDMA system. The terminal is handed off from a first base station (with a first P_REV) to a second base station (with a second P_REV) while it is in an active (data or voice) call with the first base station. The second P_REV is later than the first P_REV. The active call may be maintained between the terminal and second base station using a first service configuration previously established via the first base station for the active call. A second service configuration may be established via the second base station for the active call. This may be achieved by (1) querying the terminal, (2) assignment by the second base station, or (3) initiation by the terminal. The active call may then be maintained using the second service configuration if available.

A system and various methods and apparatus for efficient communications of data across various protocol layers are disclosed. A control system () segments each message of a plurality of messages into a plurality of segments. A segment identification () is incorporated in each segment () identifying each segment as one of a start segment, a middle segment and an end segment of each message. Moreover, a sequence number () is incorporated in each segment of the plurality of messages in a stream of messages (). The stream of messages () may include control messages () and short message service messages (). The plurality of segments is transmitted by a transmitter () in an order of the sequence number () from a source to a destination.

Techniques for reliable transmission of higher priority data within a frame are disclosed. In one aspect, an inner code is applied to one or more partial segments of a transmitted data frame in addition to any outer code applied to the entire frame. In another aspect, inner coded segments of a received frame are decoded when decoding of the outer code indicates one or more errors within the frame. The inner coded segment is retained when the inner decoding decodes without error. Various other aspects are also disclosed. These aspects have the benefits of reducing the number of retransmissions of higher priority data, as well as reducing delay for time-sensitive segments of the frame. The result is more efficient use of bandwidth, more responsiveness to higher priority segments, such as signaling traffic, and capacity, power, and other efficiencies associated therewith.
