Introduction (Background) The use and general aspects of the A-bis interface are given in specification 3GPP TS 48.05
26、1. The split of telecommunications functions and management procedures between BSC and BTS are defined in specification 3GPP TS 48.052. Specification 3GPP TS 48.056 defines Layer 2 of the signalling messages. The general aspects of NM are defined in specification GSM 12.00. Qx interface and protocol
27、 stack are defined in specification GSM 12.01. GSM 12.06 provides the functional requirements supported by the present document. The NM procedures and messages to support these operations over the A-bis interface are specified here. Specification GSM 12.20 provides the information model as seen on t
28、he OMC-BSC interface. Interworking between this model and the NM messages and procedures provided here is specified in GSM 12.22. ETSI ETSI TS 152 021 V15.0.0 (2018-07)83GPP TS 52.021 version 15.0.0 Release 151 Scope The present document addresses the network management messages and procedures acros
29、s the A-bis interface, which is defined as Qx in GSM. The information model included here defines the objects and how they are addressed for purposes of operations and maintenance activities. There is a requirement for the A-bis interface to be open to allow interoperation between BTSs of different
30、manufacturers working to the same BSC.

37、formation Model 5.1 Managed Objects The BCF mentioned in 3GPP TS 48.052 and 3GPP TS 48.056 is the agent at the BTS end of the A-bis O - operability: whether or not the resource is physically installed and working. The present document defines the following three state management attributes to repres
38、ent the management state of a managed object: - administrative state; - operational state; - availability status (this elaborates the operational state). 5.3.1 Administrative State Administrative states of the managed objects can be controlled only by the BSC. In fact, the control of resource usage
39、comes from the MSC). ETSI ETSI TS 152 021 V15.0.0 (2018-07)143GPP TS 52.021 version 15.0.0 Release 15Setting the administrative state of a Channel to locked means that it has to discontinue all transmission and reception of information on Air interface and all telecommunication (traffic and signalli
40、ng) information transmission on A-bis interface. Setting the administrative state of a Radio Carrier to locked means that it has to discontinue all RF emission on Air interface for the frequencies it is responsible. Setting the administrative state of a Baseband Transceiver to locked means that it h
41、as to discontinue all telecommunication tramissions and the Channels which are affected should indicate that they are Disabled or Degraded. Setting the administrative state of a BTS to locked means it has to discontinue all RF emission on all Radio Carriers and all telecommunication transmissions on
42、 all Channels of all Baseband Transceivers, i.e., Radio Carriers, Channels and Baseband Transceivers are in Disabled, Dependency state. The administrative state at the BTS site is also used to provide information e.g., for a local MMI user at a BTS site. The locked state of a 12.21 managed object me
43、ans that BSC has disconnected all the calls that go through the resource that is represented by the managed object. No new traffic is connected through this resource any more. The shutting down state means that no new traffic is connected through this resource any more. The on-going calls remain. Th
44、e unlocked state means that new traffic is allowed through the resource represented by the managed object. 5.3.2 Operational State and Availability Status ITU-T Recommendation X.731 gives the following definitions for the values of the operational state attribute: - disabled: the resource is totally
45、 inoperable and unable to provide service to the user(s); - enabled: the resource is partially or fully operable and available for use. In the present document the value Disabled represents the following conditions that the resources could have: - hardware or software is not installed; - power is tu
46、rned off; - failure has occurred; - radio parameters has not yet been set by elementary procedures, therefore, the resource is off line. The availability status elaborates the operational state attribute. In the present document the following values are used (availability status is a set value): In
47、test: the resource is undergoing a test procedure. Failed: the resource has an internal fault that prevents it from operating. The operational state is disabled. Power off: the resource requires power to be applied and is not powered on. The operational state is disabled. Off line: the resource requ
48、ires some manual and/or automatic operation(s) to be performed to make it available for the use. Dependency: the resource cannot operate because some other resource on which it depends is unavailable. The operational state is disabled. Degraded: the service available from the resource is degraded in
49、 some respect, such as in speed or operating capacity. The operational state is enabled. Not installed: the hardware or the software associated with the managed object has not been installed at the site. Operational state is disabled. Figure 2 illustrates the operational state and availability status behaviour of GSM 12.21 objects (i.e., Site Manager, BTS, Radio Carrier, and Baseband Transceiver) during initialization. The initial value of the administrative state is locked. ETSI ETSI TS 152 021 V15.0.0 (2018-07)153GPP TS 52.021 version 15.0.0 Releas
