Abstract: A method, performed by a first node is described, the method being for handling roaming information. The first node operates in a first communications network. The first node determines a set of network resources predicted to be required by a group of subscribers while roaming in a second communications network. The first node then initiates providing an indication of the determined set of resources to a second node in the second communications network. The second node receives the indication and determines whether or not an allocation of the set of resources meets a criterion. The second node then initiates performing an operation based on the determination. A third node determines data regarding a roaming behavior of the group of subscribers and provides information based on the determined data, to the first node.

Abstract: Systems and methods for investigating and addressing excessive battery drainage in a wireless device in a cellular communications system are disclosed. In some embodiments, a method in a core network of a cellular communications system comprises receiving, from an external entity, a request to investigate excessive battery drainage at a particular wireless device and initiating collection of information related to operation of the wireless device. The information comprises user plane data, control plane information, and/or network information related to the wireless device. The method also comprises collecting the information from one or more network nodes in the cellular communications system, analyzing the collected information to determine one or more root causes of excessive battery drainage at the wireless device, and initiating one or more actions in the cellular communications system to mitigate excessive battery drainage at the wireless device.

Abstract: An access regulating device (22) for a communication terminal (10) using a communication network (12) obtains an indication (I) that the communication terminal (10) is a potentially compromised communication terminal, analyses the indication (I), selects type of communication restriction based on the analysis, where a first type of communication restriction comprises barring the communication terminal (10) from using the communication network (12) and a second type of communication restriction comprises limiting the use of the communication network (12) by the communication terminal (10), and informs (B1,B2; Q) at least one network node (16, 18; 24) responsible for handling communication restrictions of the type selected for the communication terminal (10) in order for the communication network (12) to effectuate the communication restriction.

Abstract: Methods and systems for an online charging system to grant resources to a session with a terminal device when the session includes a large file or the session has a long duration. Embodiments the invention include methods performed by an electronic device for online charging in a wireless network. In one embodiment, the electronic device receives a request message for resources to set up a session with a terminal device, where the request message is sent from a core network interface to an online charging function (OCF), and where the request message indicates that the session includes a large file or that the session has a long duration. The electronic device determines that the terminal device has enough credit for the session based on the request message and grants the resources for the session with the terminal device based on the determination.

Abstract: Systems and methods are disclosed herein that relate to deferring delivery of non-Internet Protocol (IP) data in a wireless communication system via a Non-IP Data Delivery (NIDD) procedure based on a power source status of a serving Radio Access Network (RAN) node of a target wireless device. In some embodiments, a method of operation of a network node comprises receiving, from an exposure function, a NIDD request comprising data from an application server to be delivered to a wireless device via a NIDD procedure. The method further comprises making a determination as to whether to deliver the data to the wireless device via the NIDD procedure based on a power source status of a RAN node associated with the wireless device. In this manner, delivery of the non-IP data can be deferred depending on the power source status of the RAN node.
