Abstract: A method of enhanced error handling for 5G QoS operations associated with a PDU session is proposed. A QoS operation can be received via a PDU session modification procedure. In one example, the QoS operation is to create a new QoS rule for a PDU session, however, there is an existing QoS rule having the same QoS rule ID (QRI). The UE detects whether the QoS operation will causing the PDU session have no default QoS rule or have more than one default QoS rules. If the existing QoS rule is a default QoS rule, or if the new QoS rule have a default QoS rule (DQR) indication bit set to be true, then the UE rejects the QoS operation and indicates a QoS operation error to the network.

Abstract: In the method of subscriber initiated porting of a wireless number for a mobile station, a new service provider receives a porting request sent by a subscriber, and sends a profile request to a current service provider of the subscriber in response to the porting request. The profile request requests profile information on the subscriber. Subsequently, the new service provider receives the profile information for the subscriber, and sends a porting complete notification to the subscriber.

Abstract: A broadcast system for communicating multiple simultaneous broadcast messages in a telecommunications system is provided, where the telecommunications system has at least one fixed terminal for communication with one or more portable terminals. The broadcast system includes means for transmitting first messages from the or each fixed terminal for reception by portable terminals in the reception area of that fixed terminal, each first message including information that specifies channels, selected for that fixed terminal, which will be used to convey an associated broadcast message. A control means is provided for causing the or each portable terminal to receive on the specified broadcast message channels. The transmitter means then transmits from the fixed terminal the broadcast messages on the said specified broadcast channels for substantially simultaneous reception and reproduction of a broadcast message, such as an audio broadcast message, by the or each portable terminal.

Abstract: A portable phone includes an antenna. A detecting circuit detects contact of the antenna with a user or decrease the electric field intensity around of the antenna, and generates a notice signal based on the detecting result. A notifying section notifies to the user, that the antenna contacts the user, in response to the notice signal.

Abstract: A CDMA cellular system does not require accurate synchronization between all base stations and is capable of distinguishing the base stations from each other without the need for a complex process. When two element codes are multiplied with shifted timing to generate a spreading code, different codes that do not agree with each other when cyclically shifted are generated for the respective base stations. Spreading codes of the base stations are distinguished even when the base stations are not kept in synchronism with each other. In the CDMA cellular system which uses such spreading codes, when frame synchronization is achieved using a perch channel spread by a spreading code that is common to all the base stations, a signal transmitted from one of the base stations is de-spread on the basis of a first element code which is of the same timing (phase) with respect to a frame in all the base stations.
