Mobile-Terminated Call Handling During Latency-Sensitive Services

A user equipment (UE), comprising:

• memory;
• and
• a processor coupled to the memory and configured with processor-executable instructions to:
• determine a radio access technology (RAT) used for a latency-sensitive service (LSS) currently active on the UE in response to receiving an MT call invitation;
• determine whether a latency-prone service command is received,
• wherein latency-prone service commands include service commands configured to change the determined RAT used for the LSS to another RAT likely to compromise the LSS;
• reject the MT call invitation in response to determining that a latency-prone service command is received;
• and
• allow MT call alerting in response to determining that a latency-prone service command is not received.

A non-transitory, processor-readable medium having stored thereon processor-executable instructions configured to cause a processor of user equipment (UE) to perform operations comprising:

• determining a radio access technology (RAT) used for a latency-sensitive service (LSS) currently active on the UE in response to receiving an MT call invitation;
• determining whether a latency-prone service command is received, wherein latency-prone service commands include service commands configured to change the determined RAT used for the LSS to another RAT likely to compromise the LSS;
• rejecting the MT call invitation in response to determining that a latency-prone service command is received;
• and
• allowing MT call alerting in response to determining that a latency-prone service command is not received.

A user equipment (UE), comprising:

• means for determining a radio access technology (RAT) used for a latency-sensitive service (LSS) currently active on the UE in response to receiving an MT call invitation;
• means for determining whether a latency-prone service command is received, wherein latency-prone service commands include service commands configured to change the determined RAT used for the LSS to another RAT likely to compromise the LSS;
• means for rejecting the MT call invitation in response to determining that a latency-prone service command is received;
• and
• means for allowing MT call alerting in response to determining that a latency-prone service command is not received.
