Identifying hand-over targets in lightly coordinated networks
View Patent ↗In general, a method performed on a portable access terminal operating in an active mode includes detecting a presence of a personal base station. An encoded identification message transmitted from the personal base station is received, and the encoded identification message includes a unique identifier associated with the personal base station. The encoded identification message is decoded to extract the unique identifier, and the unique identifier is transmitted to a source network entity.

detecting a presence of a personal base station;
receiving an encoded identification message transmitted from the personal base station over a channel status indicator channel, the encoded identification message comprising a unique identifier associated with the personal base station and the encoded identification message being configured to be detectable by the portable access terminal within a single compressed mode gap;
decoding the encoded identification message to extract the unique identifier; and
transmitting the unique identifier to a source network entity;
wherein the encoded identification message is decoded from a plurality of eight bit status indicator portions of the channel status indicator channel;
wherein the plurality of eight bit status indicator portions are grouped into a home node B identification channel frame.
2. The method of claim 1 , wherein the portable access terminal enters a compressed mode.

5. The method of claim 1 , wherein the portable access terminal transmits the unique identifier to the source network entity in a measurement report message (MRM) or a radio resource control message (RRC).
6. The method of claim 1 , wherein the network is a circuit-switched network or a packet-switched network.
7. The method of claim 1 , wherein decoding comprises partially decoding the encoded identification message and storing a partial result.
8. The method of claim 7 , wherein the access terminal combines one or more partial results to form a full result.
9. A method comprising:
detecting, by a portable access terminal, a presence of a personal base station;
receiving, by a portable access terminal, an encoded identification message transmitted from the personal base station over a channel status indicator channel, the encoded identification message comprising a unique identifier associated with the personal base station and the encoded identification message being configured to be detectable by the portable access terminal within a single compressed mode gap;
decoding the encoded identification message on the portable access terminal to extract the unique identifier; and
transmitting the unique identifier to a source network entity, the source network entity determining whether to hand-over a session to the personal base station based on one or more predetermined factors;
wherein the encoded identification message is decoded from a plurality of eight bit status indicator portions of the channel status indicator channel;
wherein the plurality of eight bit status indicator portions are grouped into a home node B identification channel frame.
10. The method of claim 9 , wherein the source network entity transmits a relocation message to a target network entity, the relocation message being populated with the unique identifier.
11. The method of claim 10 , wherein the source network entity verifies a validity of the unique identifier before populating the relocation message with the unique identifier.
12. A system comprising:
a personal base station;
a source network entity; and
a portable access terminal in an active mode, the portable access terminal to:
detect a presence of the personal base station
receive an encoded identification message transmitted from the personal base station over a channel status indicator channel, the encoded identification message comprising a unique identifier associated with the personal base station and the encoded identification message being configured to be detectable by the portable access terminal within a single compressed mode gap;
decode the encoded identification message to extract the unique identifier; and
transmit the unique identifier to the source network entity;
wherein the encoded identification message is decoded from a plurality of eight bit status indicator portions of the channel status indicator channel;
wherein the plurality of eight bit status indicator portions are grouped into a home node B identification channel frame.
13. The system of claim 12 , wherein the portable access terminal enters a compressed mode.
14. The system of claim 12 , wherein the portable access terminal detects the presence of the personal base station by detecting a scrambling code of the personal base station.
15. The system of claim 12 , wherein the portable access terminal transmits the unique identifier to the source network entity in a measurement report message (MRM) or a radio resource control message (RRC).
16. The system of claim 12 , wherein the source network entity determines whether to hand-over a session to the personal base station based on one or more predetermined factors.
17. The system of claim 12 , wherein the source network entity transmits a relocation message to a target network entity, the relocation message being populated with the unique identifier.
18. The system of claim 12 , further comprising circuit-switched or packet-switched network architecture.
19. A non-transitory computer program product, tangibly embodied in a computer-readable medium, for executing instructions on a processor, the computer program product being operable to cause a portable access terminal operating in an active mode to:
detect a presence of a personal base station;
receive an encoded identification message transmitted from the personal base station over a channel status indicator channel, the encoded identification message comprising a unique identifier associated with the personal base station and the encoded identification message being configured to be detectable by the portable access terminal within a single compressed mode gap;
decode the encoded identification message to extract the unique identifier; and
transmit the unique identifier to a source network entity;
wherein the encoded identification message is decoded from a plurality of eight bit status indicator portions of the channel status indicator channel;
wherein the plurality of eight bit status indicator portions are grouped into a home node B identification channel frame.
