Avoiding formation of a call loop resulting from handling of a mobile terminated call in parallel with a location update in a wireless communication network

A mobility and call management entity (MCME) configured for preventing a call loop for a mobile terminated (MT) call to a mobile device (MD), the MCME comprising:

• a processor and a memory communicatively connected to the processor, the processor configured to:
• receive, at the MCME from a second MCME, a routing information request message associated with delivery of the MT call to the MD, the routing information request message comprising an indication of a gateway MCME for the MD;
• and
• determine whether the gateway MCME for the MD that is indicated in the routing information request message identifies the MCME.

A method, comprising:

• using a processor and a memory for:
• propagating, from a first mobility and call management entity (MCME) toward a second MCME, a routing information request message associated with delivery of a mobile terminated (MT) call to a mobile device (MD), the routing information request message comprising an indication of a gateway MCME for the MD;
• and
• receiving, at the first MCME from the second MCME, a release message configured to instruct the first MCME to release resources of the first MCME for the MD.
