Abstract
Described herein are mechanisms and methods that facilitate seamless handoff of an access terminal between access points (transceiver modules). A first transceiver module can be providing forward link data services to an access terminal when it requests a handoff to a second transceiver module. In response, the first transceiver module can provide data that is desirably transmitted to the access terminal to the second transceiver module. A network module can inform a plurality of transceiver modules that the second transceiver module is servicing the access terminal, and can further provide data to the second transceiver module for transmittal to the access terminal.
Claims53
A method for handoff at a target transceiver module, comprising:
- receiving data from a source transceiver module that is desirably transmitted to an access terminal;
- receiving an indication of what portion of the received data should be next transmitted to the access terminal;
- receiving data from a network module that is desirably transmitted to the access terminal;
- and
- selectively ordering and transmitting data received from the source transceiver module and the network module to the access terminal.
A communications apparatus, comprising:
- a memory that comprises instructions for:
- receiving first data from a transceiver module that is desirably transmitted to an access terminal;
- receiving second data from a network module that is desirably transmitted to the access terminal;
- and
- transmitting the first and second data to the access terminal in a proper sequence;
- and
- a processor that is configured to execute the instructions within the memory.
A computer readable medium having stored thereon computer executable instructions for:
- determining that an access terminal has requested a handoff from a first transceiver module to a second transceiver module;
- receiving data from the first transceiver module, wherein the data is desirably transmitted to an access terminal;
- receiving an indication of what data should be next transmitted to the access terminal from the first transceiver module;
- receiving data from a network module, wherein the data is desirably transmitted to the access terminal;
- and
- transmitting data received from the first transceiver module and data received from the network module to the access terminal in an appropriate sequence.
A communications apparatus, comprising:
- means for determining that an access terminal has requested a handoff from a first transceiver module to a second transceiver module, wherein the communications apparatus comprises the second transceiver module;
- means for receiving data from the first transceiver module and an indication of what data should be next transmitted to the access terminal;
- means for receiving data from a network module, wherein the data is desirably transmitted to the access terminal;
- and
- means for transmitting data to the access terminal in an appropriate sequence, the data is received from the first transceiver module and the network module.
A processor configured to execute instructions for:
- receiving data from a first transceiver module, wherein the data received from the first transceiver module is associated with sequence information;
- receiving data from a network module, wherein the data received from the network module is associated with sequence information;
- and
- transmitting data received from the first transceiver module and the network module to an access terminal in a correct sequence.
A method for handoff at a network module, comprising:
- receiving an indication that an access terminal has requested a handoff from a first transceiver module to a second transceiver module;
- and
- indicating to a plurality of transceiver modules that the access terminal is now being serviced by the second transceiver module.
A communications apparatus, comprising:
- a memory that comprises instructions for:
- receiving an indication that an access terminal has requested a handoff from a first transceiver module to a second transceiver module;
- and
- indicating to the first transceiver module and the second transceiver module that the second transceiver module is now servicing the access terminal;
- and
- a processor that is configured to execute the instructions.
A computer readable medium comprising computer executable instructions for:
- determining that an access terminal has requested a handoff from a first transceiver module to a second transceiver module;
- and
- indicating to a plurality of transceiver modules that the second transceiver module is transmitting data over a forward link to the access terminal.
A communications apparatus, comprising:
- means for receiving an indication that an access terminal has requested a handoff from a first transceiver module to a second transceiver module;
- and
- means for providing a plurality of transceiver modules with a message that indicates that the second transceiver module is servicing the access terminal.
A processor configured to execute instructions for:
- determining that an access terminal has requested a handoff from a first transceiver module to a second transceiver module;
- and
- informing a plurality of access terminals that the second transceiver module is servicing the access terminal.
