A method and apparatus are provided for a handover (HO) in an evolved Node B (eNodeB). The method includes receiving a measurement report from a user equipment (UE); transmitting, to a mobility management entity (MME), a handover required message including information indicating whether the HO is for a circuit switched (CS) network or both a CS network and a packet switched (PS) network; and receiving, from the MME, a handover command message. The information is used, by the MME, to split a voice bearer from another bearer.

A method of and an application server and user equipment for providing at least one of chat and Voice over Internet Protocol, chat/VoIP, services to the mobile user equipment in a mobile telecommunications network. The mobile user equipment comprises a chat/VoIP client for accessing a chat/VoIP service application interfacing the mobile telecommunications network. The chat/VoIP service application interfaces a plurality of proprietary chat/VoIP clients for accessing a plurality of proprietary chat/VoIP communication environments operated by a plurality of chat/VoIP service providers, for providing chat/VoIP services to the chat/VoIP client of the mobile user equipment. The chat/VoIP client and the chat/VoIP service application may be arranged such that privileged use of the mobile telecommunications network is enabled, providing a session between the user equipment and a communication environment with a predetermined or agreed Quality of Service.

A method comprises communicating, between a terminal (102) and a base station (101), an uplink control message (6001, 6003) of a random access procedure, the uplink control message (6001, 6003) comprising an indicator indicative of uplink payload data (6005, 6007) queued for transmission during the random access procedure. The method also comprises configuring the random access procedure depending on the indicator and communicating, in the random access procedure configured in accordance with the indicator, the uplink payload data (6005, 6007).
