5、ocuments which give specifications for the implementation of the European Cellular Telecommunications System. Historically, these . documents have been identified as “GSM recommendations“. u Some of these recommendations may subsequently become Interim European Telecommunications Standards (I-ETSs)
6、or European Telecommunications Standards (ETSs), whilst some continue with the status of ETSI-GSM Technical Specifications. These ETSI-GSM Technical Specifications are for editorial reasons still referred to as GSM recommendations in some current GSM documents. The numbering and version control syst
7、em is the same for ETSI-GSM Technical Specifications as for “GSM recommendations“. 3404583 0070473 739 = GSM 04.01 - version 3.0.1 - page 1 ETSI / GSM Recommendation GSM 04.01 Approved version 3.0.1 Title : MS-BS interface - General aspects and principles Release: ETSI - PT 12 Date: February 1992 Li

SCOPE This Recommendation describes the general aspects and principles relating to the recommendations for the GSM MS-BS interface. 1. GENERAL 1.1. A GSM PLMN supports a wide
10、range of services which a user accesses by a standard set of interfaces at a mobile station (MS). The mobile station is connected to the PLMN fixed infrastructure via a radio path to a base station, as shown in figure 1. 1.2. The MS-BS interface on this radio path is specified in the 04- series of r
11、ecommendations in such a way as to permit user and network technologies and configurations to evolve separately. Figure 1 - Basic interfaces for user access for a GSM PLMN. 1.3. The principles and procedures for the man-machine interface (MMI) to the MS are described in Recommendation GSM 02.30. The
12、 user may also use standard terminal interfaces within the MS. The reference configuration for the access is described in Recommendation GSM 04.02. W 3404583 0070475 501 Simple MS 2. 7 Dedicated GSM 04.01 - INTERFACE APPLICATIONS version 3.0.1 - page 3 Figure 2 shows some examples of the application
13、 of GSM MS-BS interfaces. The following cases are shown: i) access of simple handportable or vehicle mounted MSs; ii) access of an MS with multiple terminal equipment installation; iii) access of a mobile PBX or LAN; In addition, the figure identifies internetwork interfaces for connections to: iv)

The REQUEST primitive type is used when a higher layer is requesting a service fr
15、om the next lower layer. The INDICATION primitive type is used by a layer providing a service to notify the next higher layer of activities related to the primitive type REQUEST. The RESPONSE primitive type is used by a layer to acknowledge receipt, from a lower layer, of the primitive type INDICATION. The CONFIRM primitive type is used by the layer providing the requested service to confirm that the activity has been completed.
