The method includes: detecting whether data transmitted in a received GTP-U data packet is data of a predetermined type; if a result of the detection is that data transmitted in the GTP-U data packet is data of a predetermined type, decapsulating the GTP-U data packet, to obtain the data of the predetermined type and a destination address of the data of the predetermined type; and sending the data of the predetermined type and the destination address to a message gateway, so that the message gateway forwards the data of the predetermined type according to the destination address. A gateway includes: a detection module, a decapsulation module, and a sending module. A message gateway includes: a receiving module and a forwarding module.

Data transmission method, apparatus and system

Embodiments of the present invention provide a data transmission method, device, and system. A terminal device determines whether a data volume of uplink data to be sent is less than a preset data volume threshold. If the data volume of the uplink data to be sent is less than the preset data volume threshold, the terminal device establishes an RRC connection to a base station and sends an RRC connection completion message that carries the uplink data to the base station, so that the base station sends the uplink data to an MME by using a signaling message between the base station and the MME. The MME further sends the uplink data to a corresponding application server by using a signaling message between the MME and a P-CSCF.

The user equipment (UE) and the Mobility Management Entity (MME) in an evolved 3GPP system generate authentication material that can be carried inside a packet switched network temporary mobile station identifier (P-TMSI) signature field of a Universal Mobile Telecommunications System (UMTS) signaling message from the UE to a UMTS/GPRS serving GPRS support node (SGSN) in a UMTS or GPRS Terrestrial Radio Access Network (UTRAN) or in a GSM/Edge Radio Access Network (GERAN), as well as from the SGSN to the MME of the evolved 3GPP system. The MME authenticates a context transfer request from the UTRAN/GERAN system based on the transferred authentication material and knowledge of how to create or to verify the authentication material. Additionally, the MME and the UE derive or verify authentication material, based on at least one user-specific key, for embedding in the P-TMSI signature field in legacy 3GPP signalling.

The invention relates to assigning a mobile communications terminal having a temporary subscriber identity and/or an assigned routing parameter to a core network node of a core network provider when changing from a first to a second core network area.

In order to transmit at least one group message to at least one group consisting of one or more subscriber devices of a radio communications network, the respectively assigned, higher order radio network control unit specifically controls whether and/or how many subscriber devices per radio cell are currently registered with the respective group.

Method for transmitting at least one group message, associated radio communication network, subsystem and mobile communication device

In the transmission of a message (LU) from a subscriber station (MS), a cell recognition signal (e.g. CI) identifying the current radio cell (e.g. C) in which the subscriber station (MS) is located is transmitted towards the mobile radio system with it and stored in a subscriber database (NVLR) of the mobile radio system. The stored cell recognition signal (e.g. CI) makes it possible to call the subscriber station (MS) via a radio message to the most recently used radio cell(s) (e.g. C) and possibly also to its/their neighboring radio cells. This reduces the signaling load on the transmission of the radio message (effective paging) in the area where there are radio cells. It is possible to derive the location information on the radio cell plane, which consists of the cell recognition to identify the radio cell last used by the subscriber station, without any additional signaling load.

The invention is directed to a method and to a communication system for handling a packet service with a packet-based core communication network (CNW) and an access communication network (ANW). According to the invention, the transmission of multimedia data in the packet data can be controlled by the edge node (EN) arranged at an interface between the core communication network (CNW) and an access communication network (ANW) and can be integrated into the data transmission from and to the mobile communication device (MS) via the air interface of the access communication network. The advantage of the invention is that the edge node enables an active intervention into the signalling of the transmission of the multimedia data as packet data, i.e., this signalling need no longer ensue transparently to the mobile communication device. Another advantage is that, due to the integration of the control of the multimedia data transmission, the data streams can be adapted better to the radio resources and/or to the demands made of the mobile communication device.

Method and communication system for handling a packet service

In order to transmit data packets for a packet data service in a cellular mobile radio network, in each case one channel (TCH) in the radio transmission system (BSS) of the mobile radio network is reserved and linked to a transmission channel (NUC), which leads to a separate service network node (GSN), to form a continuous data channel. Data packets and signalling information are transmitted jointly via the data channel in a single data protocol between the mobile subscriber station (MS) and the service network node (GSN). In this way, signalling information and data packets are transmitted in only one protocol, to be precise the data protocol. By using only the data protocol for the joint transmission of the data packets and signalling information, there is a reduction in the signalling load and the channel seizure duration in the mobile radio network in comparison with the solution with two separate protocols for signalling and data.

Method for transmitting data packets according to a packet data service in a cellular mobile radio network provided for voice and data transmission

At least one virtual location area identifier (SG-LAC) that does not correspond to any of the location area identifiers for real location areas in the mobile radiotelephone network is allocated to a packet data service network node (SGSN) with which a packet data service is controlled in the mobile radiotelephone network for the transmission of one or more data packets. This is employed by a mobile switching center for the implementation of the functions in the location area management. As a result thereof, a common and efficient management of location areas (locations areas, routing areas) can be achieved upon involvement of the packet data service in the cellular mobile radiotelephone network without the standard interfaces and procedures for the mobile switching center having to be modified for this purpose.

Method and arrangement for the location area management in a cellular

A transmission channel (TCH/F) of the current radio cell, in which the mobile subscriber station (MS) is located, is directly assigned to the mobile subscriber station (MS) via a signaling channel.multidot.(CCCH) by the mobile radiotelephone network (GPNW), given a request for transmission of data packets (DAT1, DAT2) in the reverse transmission direction. The direct assignment of the transmission channel of the current radio cell to the mobile subscriber station enables the transmission of data packets without a previous sending of the paging message, and effects by comparison a shortening of the initial delay in the data packet transmission in the direction of the mobile subscriber station. Moreover, by omission of the paging message, the signaling load can be reduced during data packet transmissions in the reverse transmission direction, which is particularly advantageous given a plurality of brief data packet transmissions.
