摘要:
A method is disclosed for operating a wireless telecommunication system for providing a Multimedia Broadcast/Multicast Service MBMS broadcast transmission from a network operator (10) to a mobile station (100). A first step determines a minimum bit rate requirement to broadcast a MBMS message and a number of radio blocks per time period that are required to satisfy the bit rate requirement. A second step allocates the determined number of radio blocks in accordance with a multislot transmission technique, wherein a plurality of time slots are used per frame, such that the mobile station is provided with at least one idle radio block between two active MBMS transmission periods. The at least one idle radio block may occur between two active MBMS radio blocks. A third step transmits the determined radio block allocation to the mobile station. In the preferred embodiment the step of determining may include a consideration of radio channel conditions and a multislot class of the mobile station. In one embodiment the step of allocating attempts to maximize the number of idle radio blocks and the mobile station, during the idle radio block, performs at least one of entering a reduced power consumption mode of operation, or entering a neighbor channel measurement mode of operation. In another embodiment the step of allocating allocates radio blocks so as to complete the data transmission within the shortest period of time.
摘要:
A method of operating a mobile communication system supporting data transmission between a mobile station (MS) and a network in a number of a different packet data protocols (PDPs) including a point-to-multipoint-multicast (PTM-M) protocol. PDP data is formatted and unformatted by a subnetwork dependent convergence protocol (SNDCP) according to the PDP of data. The PDP is identified to the SNDCP by a protocol identifier transmitted between the network and the mobile station. In order to allow a MS to receive a PTM-M in an IDLE state, a unique protocol identifier is permanently assigned to PTM-M transmissions whilst other identifiers are dynamically assigned to other PDPs by the network.
摘要:
A method for quickly de-allocating physical channels (PDCH) assigned to packet switched calls in a GPRS supporting GSM digital cellular telephone network. An PDCH de-allocation RLC/MAC control message is broadcast to listening mobile stations from a base station subsystem (BSS) and contains a temporary flow identity (TFI) which is recognised by the listening mobile stations (MS). The mobile stations respond by terminating packet switched data transmissions on the identified PDCHs. The RLC/MAC message also identifies the number of PDCH time slots which can be used before de-allocation must occur.
摘要:
The scope of the present invention is a method for data transfer in a digital mobile communications system, in which method it is handled data in certain layers according to certain protocols, in a certain layer out of said layers it is transferred user data in radio blocks (RB) over a physical radio channel between a mobile station and a fixed mobile communications network, for the transfer of said certain layer it is formed in the radio block (RB) a payload of a certain size comprising check bits (CHB) connected with the performing of the transfer and transfer bits (TB) available for the transfer of user data, each radio block (RB) is channel coded using a certain coding method and the size of said payload is dependent on the coding method. In the transfer bits (TB) of the radio block to be coded using at least a certain coding method it is transferred user data in a first part of the transfer bits and in a second part of the transfer bits it is transferred fill bits in such a way that it is chosen for the transfer of user data a number of transfer bits divisible by eight.

摘要:
Establishing a data communications session involves determining a personal characteristic associated with a user of a terminal. A predetermined criterion for allowing establishment of the data communications session based on the personal characteristic is obtained. A token is embedded in a signaling message used to establish the data communications session. The token represents at least one of the personal characteristic and the predetermined criterion. The signaling message is communicated with a network entity capable of allowing users to establish the data communications session. The data communications session is established via the network entity if the personal characteristic satisfies the predetermined criterion.

Various embodiments are described relating to multimedia communication using multiple devices in a network. In an example embodiment, a request for a communication session may be received at a first server. Parameters associated with the communication session may be negotiated. One or more of the devices included in a group of one or more devices associated with a first user may be selected for receipt of one or more portions of a requested transmission based on the negotiated parameters.

A system and method for providing additional information to conference participants with regard to a predefined conference event such as scheduled conference. In various embodiments, outgoing conference indications include an identifier that indicates to a recipient that the conference invitation is being sent due to the occurrence of a scheduled event and/or due to the occurrence of other conditions being met.
摘要:
The invention relates to retrieving a conversation or part of the conversation from a database to a terminal. The database contains one or more groups of messages having a first identifier. Each group of messages comprises messages of a conversation. Each message in the group may also have a second identifier. To retrieve the message a group of messages is selected from the database. Then, a message from the selected group of messages is selected and a request is formed. The request is included with the first identifier indicating the selected group of messages. It is also possible that the second identifier indicating the selected message in the selected group of messages is also included in the request. The request is transmitted to a network element controlling the database. The selected message is searched from the database on the basis of the first and the second identifier. If the selected message is found, it is transmitted from the database to the terminal.
