Abstract
A method, system, and apparatus are described for managing a device in a mixed wireless communication system. A device may decide to scan or not scan for a cell based on (or at least on) updating information. The updating information may be used together or individually. The updating information may be maintaining a time window in conjunction with a device's motion status, maintaining a list that tracks cell identity in areas of non-service, or utilizing network deployment information.
Claims20
A method for managing a device in a mixed wireless communication system, comprising:
- determining if a first network supports circuit-switched (CS) services;
- based at least on determining that the first network does not support circuit-switched services:
- connecting to a second network that supports circuit-switched services;
- adding at least one of a location area identity (LAI) and a routing area identity (RAI) of the second network to a circuit-switched fall back (CSFB) black-list;
- detecting a new serving network;
- and
- comparing at least one of the new serving network's LAI and RAI to the respective LAI and RAI in the CSFB black-list;
- and
- determining to scan for another network when at least one of the new serving network's LAI and RAI is not found in the CSFB black-list.
An apparatus for managing a device in a hybrid wireless communication system, comprising:
- a transceiver configured to receive and transmit to and from an LTE (3GPP long term evolution) cell and a 2G/3G cell;
- a memory;
- and
- at least one processor coupled to the transceiver and the memory, configured to:
- determine if the LTE cell supports circuit-switched fallback (CSFB),
- based at least on determining the LTE cell does not support CSFB:
- connect to a first 2G/3G cell,
- add at least one of a location area identity (LAI) and a routing area identity (RAI) of the first 2G/3G cell to a black-list,
- detect a new 2G/3G cell, and
- compare at least one of the new 2G/3G cell's LAI and RAI to the black-list, and
- decide to scan for another LTE cell when at least one of the new 2G/3G cell's LAI and RAI is not found in the black-list.
A computer-program storage apparatus for managing a device in wireless communication system comprising at least one memory having one or more software modules stored thereon, the one or more software modules being executable by one or more processors and the one or more software modules comprising:
- code for determining if an LTE (3GPP long term evolution) cell supports circuit-switched fallback (CSFB);
- code for based at least on determining the LTE cell does not support CSFB:
- code for connecting to a 2G/3G cell;
- code for adding a location area identity (LAI) or a routing area identity (RAI) of the 2G/3G cell to a CSFB black-list;
- code for detecting a new 2G/3G cell;
- and
- code for comparing the new 2G/3G cell's LAI or RAI to the CSFB black-list;
- and
- code for deciding to scan for another LTE cell when the new 2G/3G cell's LAI or RAI is not found in the CSFB black-list.
