BSSMAP PROTOCOL PDF

At the physical layer, it uses a 2-Mbps PCM30 link. One or more Kbps timeslots are used to carry signaling information. The connection-oriented services are used for dedicated procedures such as handover and assignment procedures. BSS management application part. Direct transfer application part. The DTAP data is user information and carries messages related to call control and mobility management between two users, i.

SS7 signaling on the Ls interface may be supported using 56 kbps or 64 kbps digital signaling channels. These may be supported within either E1 or T1 physical links. For the SMLC, the requirements in these recommendations for a signaling end point are applicable. For the MSC, the requirements in these recommendations for both a signaling end point and signaling transfer point STP are applicable.

Several functions of the SCCP are not used on the Ls interface: error detection, receipt confirmation, flow control. Support of only SCCP protocol classes 0, 1 and 2 is required. Negotiation of protocol class and flow control is not required for protocol class 2. For protocol class 2, support of only a single connection section is required. Use of multiple connection sections is a national concern.

Connection establishment shall be instigated when the positioning attempt commences or when a signaling link to a type A LMU needs to be established. Connection release shall be instigated when the positioning attempt has been completed or has failed or when a signaling link to a type A LMU needs to be released.

If a user-out-of-service information or signalling-point-inaccessible information is received by an MSC or SMLC, no new attempt to establish SCCP connections towards the affected point code shall be started until the corresponding user-in-service information or signalling-point-accessible information is received.

When a user-out-of-service information or signalling-point-inaccessible is received, an optional timer may be started. If the timer expires all the SCCP connections towards the affected point code shall be released.

When the user-in-service or signalling-point-accessible is received, the timer is stopped.

GSM Interfaces and Protocols (Global System for Mobile Communication (GSM)) Part 3

In the case of point-to-point calls the BSSAP uses one signalling connection per active Mobile Station having one or more active transactions for the transfer of layer 3 messages. In the case of a voice group or broadcast call there is always one connection per cell involved in the call and one additional connection per BSS for the transmission of layer 3 messages. There is an additional connection for the speaker in a broadcast call or the first speaker in a voice group call up to the point at which the network decides to transfer them to a common channel. Additional connections may also be required for any mobile stations in the voice group or broadcast call which the network decides to place on a dedicated connection. Connection oriented procedures are used to support the DTAP.
