Abstract: The invention describes a method for dynamic switching between a control plane data transmission and user plane data transmission avoiding the Detach and consecutive re-attach procedure or TAU procedure. In particular the decision for switch between the different transmission schemes is based on various criteria like the size of the data packet or on total amount of data, etc.

Abstract: A system (1) is disclosed in which a network entity determines whether a radio bearer should be maintained or released for a communications device (2). The communications device (2) establishes the radio bearer via a base station (5) of the communications system (1) and communicates data using the established radio bearer. The communications device (2) determines whether any further data is to be sent or received and/or whether a user-plane connection is required. The communications device (2) then provides information to the network entity identifying a result of said determination for use in determining whether the radio bearer should be maintained or released.

Abstract: This disclosure provides a User Equipment (UE) (3), including a receiver (31) and a controller (34). The receiver (31) is configured to receive a control plane data back-off timer included in a Service Accept message from a network. The controller (34) is configured to consider a current data transfer via a control plane as successful based on the Service Accept message and not to initiate data transfer via Control Plane Cellular Internet of Things (CIoT) Evolved Packet System (EPS) Optimization while the control plane data back-off timer is running.

Abstract: The invention provides for a wireless communications terminal (502), and related system and method, for wirelessly communicating with a network (504, 506). The terminal (502) is arranged to transmit, as part of a wireless connection establishment procedure for forming a wireless connection between the terminal (502) and the network (504, 506), wireless-connection establishment signalling (510) including a small-data indicator to indicate to the network (504) that transmission of an amount of data below a threshold value is required from the terminal (502) by way of the wireless connection to the network (504, 506).

Abstract: A communication system is disclosed in which a control node generates configuration data for each of a plurality of MMEs operating in overlay networks. The configuration data defines a type of user equipment (UE) or a type of UE traffic to be serviced by each MME. The MME configuration data is provided to a base station and used to control selection of an MME to service a request from a UE. The control node monitors network traffic within and across the overlay networks and can reconfigure one or more MMEs to service different UE traffic types. This allows for improved flexibility in load balancing with overlay networks

Abstract: A communication system (100) is disclosed which uses system frames of a first and a second type. In a system frame of the first type communication with a mobile telephone (3) is subject to a restriction and in a system frame of the second type communication with said mobile telephone (3) is not subject to said restriction. It is determined whether or not to communicate with said mobile telephone (3), in a current system frame, in dependence on whether the current system frame is a first type of system frame or a second type of system frame.

Abstract: A communications system is described in which a core network apparatus provides a configuration for accessing a packet data network by a mobile communications device when operator determined barring is in place. Also disclosed are signalling messages used to control the setting up of the packet data connection, which messages are sent between a device in the core network and the mobile communications device.

Abstract: A system is disclosed in which a communications device communicates via a cell operated by a base station of a communications network. The communications device identifies that transmission of data to a communications node coupled to the communications network has been triggered; determines whether an indication of radio quality in the cell meets a required radio quality criteria responsive to the transmission being triggered. The transmitting element transmits the data to the communications network after a delay if the quality of radio signals does not meet the required radio quality criteria, and without the delay if the quality of radio signals meets the required radio quality criteria.

Abstract: There is a new market requirement that a network slice needs to be deployed in area that does not overlap with the already deployed Tracking Areas and/or has a limited lifetime. As the latest 3GPP specification cannot fulfil the new market requirement, 3GPP specifications need to be enhanced.
A method of a communication apparatus includes receiving Single Network Slice Selection Assistance Information (S-NSSAI), first information indicating where the S-NSSAI is valid and second information indicating when the S-NSSAI is valid. The method includes sending the S-NSSAI, the first information and the second information.
