Abstract: A signaling method in a wireless digital telecommunication system between a base station and a terminal, where the signals between the base station and the terminal are generated from bursts comprising symbols, the bursts comprising a known training sequence. The symbols are used for generating a second training sequence of the same length as the known training sequence and a burst comprising said training sequence to be used for transmitting signalling messages. The number of training sequences used can be restricted to two, whereby conventional user data is sent in the burst comprising the known training sequence and information deviating from the conventional user data is sent by the burst comprising the second training sequence, and the stealing symbols in the burst can be used for specifying a signalling message to be transmitted.

Abstract: The invention concerns the control of connections in cellular telecommunication systems. According to the invention, the available radio resources are controlled by allowing only certain conbinations of transport formats to be used by a single user. The inventive method restricts the combinations of bearer bit rates which can be used, without strictly limiting some bearers from using highest bit rates. This inventive approach allows flexible overall control of radio resources, while retaining the possibility of bearers to select between different bit rates.
Abstract translation: 本发明涉及蜂窝电信系统中的连接的控制。 根据本发明，通过仅允许单个用户使用某些传输格式的混合来控制可用的无线电资源。 本发明的方法限制了可以使用的承载比特率的组合，而不严格限制一些承载使用最高比特率。 本发明的方法允许对无线电资源的灵活的总体控制，同时保留承载者在不同比特率之间进行选择的可能性。

Abstract: The invention comprises a method for establishing a signaling connection with a mobile station, which method is particularly applicable to third-generation mobile communications networks. A database is created at a node of a mobile communications network, and a mobile station connected with the network sends to said database information about all its subscriber identities (403). In the database, information is added (404) to the subscriber identity information which may be useful when said mobile station is paged (410, 411). Such contactability information includes e.g. the mobile station's location information, information about existing signaling connections and information about the primary paging channel monitored by the mobile station. The contactability information is updated according to changes detected in the status of the mobile station (406). The database will be discontinued for a mobile station that has had no connections for a predetermined time. The method reduces paging channel load in cells, reduces the need of mobile stations to listen to paging channels and makes radio access networks connections to multiple core networks more practical.

Abstract: In connection-oriented switching of packet data in known mobile communications systems, resources of the transmission path between the serving node (SGSN) and the radio network subsystem (RNS) and memory resources of the radio network subsystem are reserved unnecessarily due to the burst-like nature of packet data. Thus the transmission network's limited address space and the radio network subsystem's management resources are consumed. The invention concerns such connection management in a mobile communications system, which is suitable for packet-switched data transmission. The method according to the invention is characterized in that the logical connection between the serving node (SGSN) and the radio network subsystem (RNS) is released, so that the logical connection between the serving node (SGSN) and the mobile station (MS) remains, and the released logical connection is reconnected, when relaying of user data starts.

Abstract: A method comprises using a first protocol to define a protocol initialization unit at a first termination point of a first protocol. The protocol initialization unit contains predefined information pertaining to initialization of a second termination point of the first protocol. The method also comprises transferring the protocol initialization unit from the first termination point to a second termination point by a second protocol for relocating the first protocol. The first protocol is relocated due to one or more of the following: handoff of a mobile station from one service area to another service area, network optimization, load balancing, hardware congestion, connection quality improvement and network element failure.

Abstract: An automatic repeat request mechanism (such as Type II/III hybrid ARQ) which includes (soft or hard) combining of initially transmitted and retransmitted versions of a packet, is provided for retransmission of erroneous packets. According to the present invention, in association with each retransmission, there is outband signaling from a transmitter to a receiver that unambiguously indicates when, e.g. the exact time or physical location, the first transmission of the packet was carried out, so that it is possible to combine the retransmitted version with the previous version(s) of the packet. Soft combining requires that the initial packet and the retransmitted packet be identical. In an embodiment of the invention, in order to overcome this problem, the information that needs to be changed between the initial transmission and the retransmission(s) of a packet is sent outband with other outband signaling information. Thus, the retransmitted packet can be maintained unchanged and the requirement for identical packets in soft combining is met.
