Handoff Between Base Stations Of Different Protocol Revisions In A Cdma System

View page
US Patent:
7961682, Jun 14, 2011
Filed:
Apr 11, 2002
Appl. No.:
10/122289
Inventors:
Lijun Zhao - San Diego CA, US
Jun Wang - San Diego CA, US
Assignee:
QUALCOMM Incorporated - San Diego CA
International Classification:
H04W 4/00
US Classification:
370331, 455436
Abstract:
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.

Inner Coding Of Higher Priority Data Within A Digital Message

View page
US Patent:
20030101404, May 29, 2003
Filed:
Sep 9, 2002
Appl. No.:
10/238951
Inventors:
Lijun Zhao - San Diego CA, US
Lorenzo Casaccia - San Diego CA, US
International Classification:
H03M001/36
H03M013/00
US Classification:
714/755000
Abstract:
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.

System And Method To Perform Access Control And Paging Using Femto Cells

View page
US Patent:
20100112982, May 6, 2010
Filed:
Nov 2, 2009
Appl. No.:
12/610853
Inventors:
Damanjit Singh - San Diego CA, US
Lijun Zhao - San Diego CA, US
Oronzo Flore - Ostuni, IT
Rajarshi Gupta - Santa Clara CA, US
Manoj M. Deshpande - San Diego CA, US
Andrei D. Radulescu - San Diego CA, US
Assignee:
QUALCOMM Incorporated - San Diego CA
International Classification:
H04W 12/00
H04W 68/00
US Classification:
455411, 455458
Abstract:
Methods and apparatus for performing femto cell access and paging control for a wireless access terminal (e.g. a cell phone handset) within a network of multiple femto cell components (e.g. HNBs) and an access control component (e.g. a mobile operator's core network). One method comprises storing a first group association of femto cells, using common characteristic (e.g. a Closed Subscriber Group ID), storing a second group association among access terminals (e.g. defining which access terminals belong to which Closed Subscriber Group), and authorizing access to an access terminal to all of the femto cell components belonging to the first group. The access terminal may receive pages from any or all of the femto cells belonging to the group. Residential and enterprise deployments may be co-located.

View page
US Patent:
20100203891, Aug 12, 2010
Filed:
Feb 9, 2010
Appl. No.:
12/703065
Inventors:
Sumeeth Nagaraja - San Diego CA, US
Mehmet Yavuz - San Diego CA, US
Andrei D. Radulescu - San Diego CA, US
Damanjit Singh - San Diego CA, US
Jen M. Chen - San Diego CA, US
Peter H. Rauber - San Diego CA, US
Aziz Gholmieh - Del Mar CA, US
Sanjiv Nanda - Ramona CA, US
Lijun Zhao - San Diego CA, US
Assignee:
QUALCOMM Incorporated - San Diego CA
International Classification:
H04W 36/00
US Classification:
455436
Abstract:
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.

Paging For Local Ip Access Packets

View page
US Patent:
20100284387, Nov 11, 2010
Filed:
May 5, 2010
Appl. No.:
12/774538
Inventors:
Lijun Zhao - Santa Monica CA, US
Parag Arun Agashe - San Diego CA, US
Peter H. Rauber - San Diego CA, US
Andrei Dragos Radulescu - San Diego CA, US
Damanjit Singn - San Diego CA, US
Gavin Bernard Horn - La Jolla CA, US
Gerardo Giaretta - San Diego CA, US
Assignee:
QUALCOMM Incorporated - San Diego CA
International Classification:
H04W 48/20
US Classification:
370338
Abstract:
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.

Handoff Between Base Stations Of Different Protocol Revisions In A Cdma System

US Patent:
20110235616, Sep 29, 2011
Filed:
Jun 8, 2011
Appl. No.:
13/155941
Inventors:
Lijun Zhao - San Diego CA, US
Jun Wang - San Diego CA, US
Assignee:
QUALCOMM Incorporated - San Diego CA
International Classification:
H04W 36/18
US Classification:
370331
Abstract:
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.
