US 9,002,364 B2 · System, method, and computer-readable medium for concurrent termination of multiple calls at a mobile terminal

Abstract

A system, method and computer-readable medium for allocating multiple subscriptions to a single mobile terminal thereby allowing concurrent termination of multiple calls at the mobile terminal are provided. A mobile terminal adapted to terminate multiple concurrent calls is described. In one implementation, a network need not have any configuration data regarding the multi-line capabilities of the mobile terminal. In other implementations, network-centric mechanisms are provided for allowing multiple concurrent calls to be terminated by a mobile terminal. Multiple concurrent calls may be terminated at a mobile terminal on separate carrier frequencies or alternatively may be terminated on a common carrier frequency.

Dependent claims

A method of terminating calls to a mobile terminal, comprising:

receiving a call request directed to the mobile terminal;
determining the mobile terminal is currently terminated with an in-progress first call;
determining the mobile terminal is available to accept a second call;
identifying a different carrier frequency that has more time slots available than a carrier frequency allocated to the first call;
setting up the second call with the mobile terminal while the first call is maintained in progress, wherein the second call is setup by allocating a time slot of the different carrier frequency that is different from the carrier frequency allocated to the first call;
wherein the first call is allocated on a first carrier frequency;
determining the first carrier frequency has no time slots available for another call;
identifying a second carrier frequency that has a plurality of available time slots;
and
performing an intra-cell handover of the first call from the first carrier frequency to the second carrier frequency.

7 more elements

A mobile terminal for deployment in a network system, comprising:

a first antenna;
a first transceiver coupled to the first antenna;
a processing system that executes computer-executable instructions for terminating calls with the mobile terminal, wherein the mobile terminal is adapted to concurrently receive a first call on a first channel and a second call on a second channel, wherein the processing system identifies a different carrier frequency that has more time slots available than a carrier frequency allocated to the first call, and wherein the processing system provides mid-call services for the second call, and wherein the second call is setup by allocating a time slot of the different carrier frequency that is different from the carrier frequency allocated to the first call;
a second antenna;
and
a second transceiver coupled to the second antenna;
wherein the first call is received on a channel of a first carrier frequency over the first antenna and the first transceiver, and wherein the second call is received on a channel of a second carrier frequency over the second antenna and the second transceiver;
wherein the first call is allocated on a first carrier frequency;
instructions that determine the first carrier frequency has no time slots available for another call;
instructions that identify a second carrier frequency that has a plurality of available time slots;
and
instructions that perform an intra-cell handover of the first call from the first carrier frequency to the second carrier frequency.
