A method of performing a packet domain event report by a mobile termination (MT) of a user equipment (UE) to a terminal equipment (TE) of the UE; and the UE therefore are discussed. The method according to one embodiment includes receiving, by the MT from the TE, a context activation request for a first packet data protocol (PDP) type; attempting, by the MT, a context activation with the first PDP type; receiving, by the MT from a network, a second PDP type assigned by the network for the context activation instead of the first PDP type; and sending, by the MT to the TE, an event message including a reason parameter indicating why the context activation request for the first PDP type is not granted.

Attention commands enhancement

A method of packet domain event reporting performed by a user equipment (UE) including a mobile termination (MT) and a terminal equipment (TE), and the user equipment thereof. The method according to one embodiment includes performing, by the MT, context activation for establishing a dual-stack bearer between the MT and a network; receiving, by the MT from the network, information indicating that the context activation of the dual-stack bearer is not possible between the network and the MT; and sending, by the MT to the TE, a message including a reason parameter for indicating a reason as to why the context activation of the dual-stack bearer is not possible between the network and the MT, when a requested Packet Data Protocol (PDP) type is Internet Protocol (IP) v4v6 and a assigned PDP type is either IPv4 or IPv6.

A method of performing Pseudo-random-Noise (PN) quadrature covering for transmitting data via an access channel. The method according to one embodiment includes receiving a 42-bit access long code mask MIand a 42-bit access long code mask MQfrom an upper layer; generating an MI mask and an MQ mask for PN quadrature covering by using certain bits of an assigned channel number for the access channel; performing exclusive OR operations on certain bits of the received access long code mask MI; performing exclusive OR operations on certain bits of the received access long code mask MQ; and transmitting signals via the access channel based on the generated 12-bit MI mask and the generated 12-bit MQ mask.

Enhanced access channel masks for xHRPD

An apparatus including a Mobile Termination (MT); a Terminal Equipment (TE); and a Terminal Adaptor (TA). The MT performs context activation. The MT receives, from the network, information indicating that the context activation of the dual-stack bearer is not granted. The MT transmits, to the TE, a response message including a reason parameter selected among a first parameter to a fourth parameter. The first parameter indicates that an Internet Protocol version 4 (IPv4) is only allowed, the second parameter indicates that an Internet Protocol version 6 (IPv6) is only allowed, the third parameter indicates that single address bearers only allowed, and the fourth parameter indicates that single address bearers only allowed and context activation of a second address type bearer was not successful. The response message further includes a context identifier allocated by the MT for an initiated context of the second address type considering three conditions.

An apparatus includes a Mobile Termination (MT) that offers functions related to communication with a network, a Terminal Equipment (TE) that offers services to a user of the apparatus, and a Terminal Adaptor (TA) that allows communication between the MT and the TE using Attention (AT) commands. A packet domain event reporting command (+CGEREP) is one type of AT command that enables or disables sending of result codes from the MT to the TE in case certain events occur in the MT for a packet domain or in the network. One such type of event is a Packet Data Protocol (PDP) context activation, for which the MT sends to the TE a result code that includes an integer type parameter to indicate the reason why a context activation request with PDP type IPv4v6 was not granted, and a context id parameter to indicate the capability of Mobile Termination for autonomously requesting a second address bearer, and the result of the second address bearer activation.

Disclosed is a method of performing Pseudo-random-Noise (PN) quadrature covering for transmitting data via an access channel. Such method is achieved by receiving a 42-bit access long code mask MIand a 42-bit access long code mask MQfrom an upper layer; generating an MI mask and an MQ mask for PN quadrature covering by using certain bits of an assigned channel number for the access channel and by performing exclusive OR operations on certain bits of the received access long code mask MIand performing exclusive OR operations on certain bits of the received access long code mask MQ; and transmitting signals via the access channel based on the generated 12-bit MI mask and the generated 12-bit MQ mask.
