Method in a UE, a network node and a client node in a wireless communications network
First Claim
1. A network node for enabling a client node to set up a communication to a User Equipment (UE) in a wireless communications network, the network node comprising:
- a receiver circuit configured to receive a text message originating from the UE and comprising UE geographic location information and a client type indicator;
a processor circuit configured to identify the client node based on the UE geographic location information and on the client type indicator, wherein the client node is of a type indicated by the client type indicator, and the client node serves an area in which the UE is located; and
a transmitter circuit configured to forward the text message to the client node enabling the client node to set up the communication to the UE;
wherein the processor circuit is further configured to;
determine whether refined UE location information is needed, and when refined UE location information is needed;
obtain refined UE location information from the UE or from another network node; and
use the obtained refined UE location information to identify an appropriate client node.

Abstract
A method and nodes for enabling a client node such as a Public Safety Answering Point (PSAP) or Location Services (LCS) client to set up a communication to a User Equipment (UE) in a wireless communications network. The method enables the client node to provide solutions that enable location aware non-voice based emergency services by means of new signalling and a new architecture. A text message may be sent from the UE to the client node via a network node, wherein the text message includes UE location information and a client indicator. The UE location information and the client indicator are then utilized to determine a client node which is most appropriate for communication with the UE.
