A method of operating a terminal device to establish a radio resource control connection with network infrastructure equipment in a wireless telecommunications network, wherein the terminal device is associated with a previously-allocated temporary identifier that identifies the terminal device within the wireless telecommunications network; the method comprising: transmitting a first message to the network infrastructure equipment comprising an indication of a first portion of the temporary identifier; and transmitting a second message, which is separate from the first message, to the network infrastructure equipment comprising an indication of a second portion of the temporary identifier.

Embodiments of the present disclosure relate to dynamical changes in access and mobility policies. According to embodiments, an Application Function entity can request the Access and Mobility related entity to modify the access and mobility policies for a terminal device after the discovery of the Access and Mobility related entity. Alternatively, the Access and Mobility related entity obtains access and mobility policies from a User Data Repository that link traffic of an application on a PDU Session towards to access and mobility policies and configure the AM policy based on a detection of traffic change done under control of a Session Management related entity. Therefore, the access setting and/or the mobility setting can be dynamically changed based on the traffic change in the application.

Techniques are described by which a network management system (NMS) is configured to monitor and/or control a wireless network based on one or more roaming quality assessments. The NMS determines one or more roaming quality assessments for each roaming event and/or each network device in the wireless network. The roaming quality assessments include one or more of a roaming latency score, a signal quality score and/or a stability score. The roaming quality assessments may further include one or more suboptimal roam scores, sticky client scores, and/or interband scores. The NMS may further detect one or more ping-pong roaming events or excessive roaming events.

The disclosed technology is directed towards detecting improbable speeds of a mobile device, which can indicate fraudulent activity with respect to the mobile device. Radio access network events and call detail records are processed to determine when a mobile device “travel jumps” between locations at improbable speeds. Events corresponding to handovers between adjacent cells are filtered out. For events corresponding to changed cell towers that are non-adjacent, further processing is performed to determine the speed of the mobile device travel between the cells. A first speed threshold is selected based on possible air travel (a cell near an airport) or a second non-air travel speed threshold is selected. If the speed of the mobile device exceeds the selected speed threshold, a travel jump is determined. Exceptions can be made for gaps in connectivity due to topography (known inconsistent reception areas) and for a mobile device shutting down and restarting.

Embodiments of the present disclosure provide a short message service processing system, which is configured to, with a short message interworking device, perform a signaling conversion in a first short message process between a short message service center and a mobility management entity or a short message service function entity, where the signaling conversion in the first short message process is a conversion from first signaling of an E interface to second signaling of a SGd interface; the short message interworking device is further configured to perform a signaling conversion in a second short message process between the short message service center and a unified data management entity/home subscriber server; and the signaling conversion in the second short message process is a conversion from the first signaling of a C interface to second signaling of a S6c interface.

When mobile terminated devices sleep, the devices might not be reachable when needed, for instance when the device is a recipient of data from a third party server. As described herein, a third party application server may inform the network that it has data to send to a particular UE or group of UEs. In an example, the mobile core network (MCN) may use information from the third party server to ensure that the UE is awake when it needs to be. For example, a given UE or group of UEs can be prevented from entering a sleep state before a data transfer is completed.
