Abstract: As a result of ISR being enabled between a portable terminal device and a network which are capable of communicating by using the communication protocols of a plurality of wireless access technologies, the portable terminal device performs position registration processing between the plurality of wireless access technologies and the portable terminal device each time a fixed period of time elapses, and the portable terminal device is able to move between the plurality of wireless access technologies that have already been registered, without conducting new position registration processing. At this time, if there is a possibility of there being a difference in ISR states (activated or not activated) between the portable terminal device and the network, the portable terminal device ignores any instructions issued by the network for ISR to be enabled in the portable terminal device.

Abstract: A wireless terminal can communicate with a first network of first type and a second network of second different type. The wireless terminal performs a packet-domain attachment to the first network and initiates a ready timer indicating that the wireless terminal is in an attached state and has recently sent data to the first network. The wireless terminal initiates an inter-system change from the first network to the second network whereby the wireless terminal becomes registered to the second network. Advantageously the wireless terminal has means for rendering the ready timer ineffective when the inter-system change is performed. The network apparatus has means for initiating its own ready timer dependent on the attachment occurring, this ready timer also indicating that the wireless terminal is in an attached state and has recently sent data to the first network.

Abstract: A wireless terminal can communicate with two radio access networks (RAN) (304, 306) of different types. The wireless terminal can register simultaneously with a RAN of the first type and a RAN of the second type and can wirelessly connect to a RAN of either the first type or the second type in a connected state. The wireless terminal when registered with both a first RAN and a second RAN and when wirelessly connected to the first RAN in the connected state, receives a mobility signal via the first RAN indicating a RAN of the second type and, in response to receiving the mobility signal and in response to being so registered with the first RAN and second RAN, transmits an access trigger signal (417). The access trigger signal indicates that the wireless terminal is to be connected to the second RAN in the connected state.

Abstract: A communication device (10) includes a communication IF (11) transmits and receives, in a layer 2, a packet having a structure that does not include a MAC address; a TCP/IP processing unit (12) transmits and receives a packet in a TCP/IP layer; and a switch (13) performs processing on the packet received by the communication IF (11) and the TCP/IP processing unit (12). When the switch (13) performs processing for transmitting, from the TCP/IP processing unit (12), the packet received by the communication IF (11), a pseudo MAC header is added to the packet and the packet is output to the TCP/IP processing unit (12). When the switch (13) performs processing for transmitting, from the communication IF (11), the packet received by the TCP/IP processing unit (12), the pseudo MAC header is deleted from the packet and the packet is output to the communication IF (11).

Abstract: In one embodiment, a mobile station (1) is capable of performing location registration procedures with first and second mobile management units (31 and 32) that respectively correspond to first and second RANs (Radio Access Networks). Further, the mobile station (1) supports ISR (Idle mode Signalling reduction) for reducing location registration procedures caused by reselection between the first RAN (21) and the second RAN (22). Furthermore, the mobile station (1) is configured to deactivate ISR in the mobile station (1) when voice service configuration information stored in the mobile station (1) is updated when the ISR is activated.
Abstract translation: 在一个实施例中，移动台（1）能够与分别对应于第一和第二RAN（无线电接入网络）的第一和第二移动管理单元（31和32）执行位置注册过程。 此外，移动台（1）支持用于减少由第一RAN（21）和第二RAN（22）之间的重选引起的位置登记过程的ISR（空闲模式信令减少）。 此外，移动台（1）被配置为当ISR被激活时更新存储在移动台（1）中的语音服务配置信息时，在移动台（1）中停用ISR。
