Problems solved by technology

Since the range of the mobile system is as far as possible when sizing the mobile system, almost every base station always has a spare transceiver unit (to process a new call as necessary), thus indicating a relative relationship between the base station controller and the base station. A large number of telecommunications channels are often unused

Embodiment Construction

[0029] Figure 1 is a flow chart of a first preferred embodiment of the method according to the invention. The flowchart in Fig. 1 is applicable, for example, to the allocation of telecommunication channels between a base station and a base station controller in a GSM system.

[0030] In block A, circuit-switched primary and secondary unassigned telecommunication channels are provided between the base station and the base station controller, i.e. the telecommunication channels are not fixedly assigned to any particular base station or transceiver unit in the base station . These telecommunication channels are classified according to their characteristics such that primary telecommunication channels are of better quality, have greater data transmission capacity, are more reliable to use or are cheaper than secondary telecommunication channels. Depending on the implementation, telecommunication channels can also be classified into more than two types.

[0031] In block B, the i...

Abstract

The present invention relates to a mobile system, which includes a base station controller (BSC) and at least a first and a second base station (BTS1, BTS2), which comprise switching means (S1 to S5) for switching transceiver units (TRX1 to TRX3) of the base stations onto a particular channel of a plurality of optional telecommunication channels between the base station controller (BSC) and the base stations (BTS1, BTS2). In order for the telecommunication channels to be utilized efficiently, the base station controller (BSC) comprises control means (1), which allocate in connection with call set-up at least one of said telecommunication channels (CH1 to CH6) to the first (BTS1) or to the second (BTS2) base station for the duration of the call, and which transmit a predetermined message on the allocated channel to the base station to which the channel is allocated, the switching means (S1 to S5) of the first and, correspondingly, of the second base stations (BTS1, BTS2) being responsive to said message for switching the transceiver units (TRX1 to TRX3) to the channel (CH1 to CH6) assigned by said message.

Description

technical field [0001] The invention relates to channel allocation on a telecommunication connection between a base station and a base station controller of a mobile system. In particular, the invention relates to a mobile system such as GSM (Global System for Mobile Communications) in which call-related telecommunication signals are transmitted over circuit-switched telecommunication channels between base stations and base station controllers. Here, a call refers to any service connection to be exchanged in the mobile system, such as a normal voice call, or eg a data call. Background technique [0002] In the GSM system, for example, calls are switched over circuit-switched telecommunication channels through the Abis interface between the base station and the base station controller, and in practice these channels may comprise, for example, 2 Mbit / s PCM (Pulse Code Modulation) connections. Gap. These PCM connection slots, ie telecommunication channels, are then permanentl...
