Abstract: A communication system is disclosed in which a home subscriber server, ‘HSS’, of a communication network, receives, from a service capability exposure function, ‘SCEF’, at least one communication pattern parameter set together with an associated validity time, stores the at least one communication pattern parameter set, and when the validity time for a communication pattern parameter set stored in the HSS expires, autonomously deletes the associated communication pattern parameter set.

Abstract: A system is described in which a default MME (9A) receives a NAS message (S501, S505) from a mobile device (3D); sends a rerouting request (S509) to a base station (5) serving the mobile device (3D) and includes information identifying a group of dedicated MMEs (9D) to which the NAS message should be rerouted. If none of the dedicated MMEs (9D) is available, then the default MME (9A) receives a message from the base station (5), the message rerouting the NAS message to the default MME (9A), instead of a dedicated MME (9D). The default MME (9A) either proceeds (S515a) to serving the mobile device (3D) or the default MME (9A) rejects (S515b) the NAS message.

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).
