摘要:
The aspects of invention relates to determining a bit rate in a communication device, the communication device including a protocol stack for transferring information to a second communication device, the protocol stack including a protocol layer, the protocol layer providing a logical channel for transferring first information through the protocol layer. According to the method, the first information is transferred through the protocol layer via the logical channel and the bit rate in the logical channel is determined on the basis of second information obtainable from the protocol layer. The invention also relates to a method of determining a bit rate when the communication device is receiving information as well as corresponding transmitting and receiving communication devices.
摘要:
Apparatus, and associated method, for improving packet data communications upon a communication path including a radio-link. Determination is made of the conditions on the radio-link when selecting the optimal size of a transmission window within which to transmit packets of data. And, retransmission time-out values are also selected responsive to the indications of the radio-link conditions.
摘要:
A system, apparatus and method for establishing circuit-switched (CS) communications in packet-switched (PS) multimedia networks such as IMS, and providing services via the PS networks to CS domain users. A dialog is established between terminals through the PS multimedia network. A service is provided to at least one of the terminals by way of the dialog. CS bearer information, including an indication that a communication flow is requested via a CS network, is communicated between the terminals by way of the dialog. A communication flow via the CS network is effected between the terminals as directed by the CS bearer information. IMS or other PS multimedia network services can thus be provided to users otherwise communicating via the CS-domain.

摘要:
A method of enabling roaming of a mobile internet-access terminal from a first to a second internet access network each of which has a home agent for routing internet datagrams between networks. The method comprises de-registering the mobile terminal from said first network and registering it with said second network and allocating to the mobile terminal a new internet address in said second network. This new internet address is transmitted to the first network's home agent which registers that address as a care-of-address or co-located care-of-address for the mobile host. Datagrams addressed to the new internet address are sent directly to the mobile host via the second network's home agent. Datagrams addressed to a previous internet address of the mobile terminal in said first network are forwarded from that network's home agent to the mobile host, via the second network's home agent.
摘要:
The invention relates to a method for transmitting multimedia messages to a wireless terminal (MS1) in a data transmission system which comprises at least one mobile communication network (HPLMN) and at least one multimedia message server (MMSV). In the method, each wireless terminal (MS1) connected to the mobile communication network (HPLMN), is allocated an address specifying said wireless terminal (MS1), and at least one data transmission connection is activated for said wireless terminal (MS1). Information on the activation of the data transmission connection for said terminal (MS1) is transmitted to the multimedia message server (MMSV).
