Abstract

A dual SIM mobile terminal, such as a Dual SIM Dual Active (DSDA) mobile terminal, connects to a network and performs a user plane or control plane positioning session through the network. When the positioning session is originated by the mobile terminal, either SIM card may be used to connect to its associated network. When the positioning session is originated by another entity in the network, either SIM card may be used for the positioning session. When the mobile terminal connects to a network for an emergency call using either SIM card and an emergency positioning session is performed through the network, the emergency positioning session is permitted only during the emergency call and an emergency callback period and permitted only on a subscription on which the emergency call originated, and no non-emergency positioning sessions with either SIM card is permitted during the emergency positioning session or emergency call.

Claims

1. A method of supporting an emergency positioning session in a dual Subscriber Identity Module (SIM) mobile terminal, the method comprising:

connecting the dual SIM mobile terminal to a network for an emergency call, wherein the network is one of a first network associated with a first subscription accessed with a first SIM card in the dual SIM mobile terminal and a second network associated with a second subscription accessed with a second SIM card in the dual SIM mobile terminal; and

performing the emergency positioning session through the network;

wherein the emergency positioning session is permitted only during the emergency call and an emergency callback period after the emergency call;

wherein the emergency positioning session is permitted only on a subscription on which the emergency call is originated;

wherein no non-emergency positioning sessions on either the first subscription or the second subscription are permitted during the emergency positioning session or during the emergency call, and wherein no non-emergency positioning sessions on either the first subscription or the second subscription are permitted during the emergency callback period after the emergency call.

2. A mobile terminal comprising:

a first Subscriber Identity Module (SIM) card that accesses a first subscription associated with a first network;

a second SIM card that accesses a second subscription associated with a second network;

a transceiver that communicates with the first network and the second network;

a processor connected to the transceiver, the processor configured to use the transceiver to connect to a network for an emergency call, wherein the network is one of the first network associated with the first subscription accessed with the first SIM card and the second network associated with the second subscription accessed with the second SIM card; and

perform an emergency positioning session through the network, wherein the emergency positioning session is permitted only during the emergency call and an emergency callback period after the emergency call, wherein the emergency positioning session is permitted only on a subscription on which the emergency call is originated, and wherein no non-emergency positioning sessions on either the first subscription or the second subscription are permitted during the emergency positioning session or during the emergency call, and wherein no non-emergency positioning sessions on either the first subscription or the second subscription are permitted during the emergency callback period after the emergency call.

3. A dual Subscriber Identity Module (SIM) mobile terminal comprising:

means for connecting the dual SIM mobile terminal to a network for an emergency call, wherein the network is one of a first network associated with a first subscription accessed with a first SIM card in the dual SIM mobile terminal and a second network associated with a second subscription accessed with a second SIM card in the dual SIM mobile terminal; and

means for performing an emergency positioning session through the network;

wherein the emergency positioning session is permitted only during the emergency call and an emergency callback period after the emergency call;

wherein the emergency positioning session is permitted only on a subscription on which the emergency call is originated;

wherein no non-emergency positioning sessions on either the first subscription or the second subscription are permitted during the emergency positioning session or during the emergency call, and wherein no non-emergency positioning sessions on either the first subscription or the second subscription are permitted during the emergency callback period after the emergency call.

4. A non-transitory computer-readable medium including program code stored thereon, comprising:

program code to connect a dual SIM mobile terminal to a network for an emergency call, wherein the network is one of a first network associated with a first subscription accessed with a first SIM card in the dual SIM mobile terminal and a second network associated with a second subscription accessed with a second SIM card in the dual SIM mobile terminal; and

program code to perform an emergency positioning session through the network;

wherein the emergency positioning session is permitted only during the emergency call and an emergency callback period after the emergency call;

wherein the emergency positioning session is permitted only on a subscription on which the emergency call is originated;

wherein no non-emergency positioning sessions on either the first subscription or the second subscription are permitted during the emergency positioning session or during the emergency call, and wherein no non-emergency positioning sessions on either the first subscription or the second subscription are permitted during the emergency callback period after the emergency call.
