Layer 3 provides the necessary supporting operations related to supplementary services and short messages service control. It also includes the actions required for mobility and radio resource management. Layer 3 contains three sublayers having the following functions: 0 Radio Resource (RR) management Mobility Management (MM) 0 Connection Management (CM) The RR sublayer contains 0 The RR management protocol 2 Copyright Telecommunications Industry Association Provided by IHS under license with EIALicensee=IHS Employees/1111111001, User=Wing, Bernie Not for Resale, 03/29/2007 21:22:17 MDTNo reproduction or networking permitted without license from IHS -,-,- 3 TINEINIS-782.04007 The Dual Tone Multiple Frequency (DTMF) transmission and Dual Tone Reception Service (DTRS) management The CM sublayer contains 0 Call Control (CC) 0 SMS support 0 Supplementary Services (SS) 4.2 Objectives The objectives of Layer 3 are to provide the means for: The establishment, operation and release of a dedicated radio channel connection, exchange of position information and support for optimal routing and single-hop MES-MES calls (RR) The transmission and reception of DTMF digits dialed by the mobile user over the air to the peer entity (MES or GS) (DTRS) 0 The location updating, authentication, Temporary Mobile Subscriber Identity (TMSI) reallocation and support for optimal routing (MM) The establishment, maintenance and termination of Circuit-Switched Calls (CC) 0 SS support 0 SMS support 4.3 General characteristics 4.3.1 Technique of description Layer 3 signaling is described in terms of The services provided by signaling Layer 3 The services assumed from signaling Layer 2 The functions of signaling Layer 3 The signaling Layer 3 functions are performed by means of the signaling Layer 3 protocols between two systems representing the MES and network sides of the radio interface (as viewed by the MES). This technical specification does not consider the distribution of signaling functions among the different network equipment. The functions of Layer 3 and its supporting lower layers provide the Mobile Network Signaling (MNS) service to the upper layers. The service interfaces to the upper layers and to the data link Layer 2 are described by the primitives and parameters as recommended in CCITT Recommendation X.200. The same technique of description is used for the three sublayers. 4.3.2 Primitives The services provided by the various sublayers are described in this technical specification. The primitives describe the elementary interactions among adjacent sublayers. Primitives consist of requests, responses, indications and confirmations. The basic syntax of a primitive is specified in GMR-104.001 5. 3 Copyright Telecommunications Industry Association Provided by IHS under license with EIALicensee=IHS Employees/1111111001, User=Wing, Bernie Not for Resale, 03/29/2007 21:22:17 MDTNo reproduction or networking permitted without license from IHS -,-,- TIA/EIA/IS-782.04007 4.3.3 Peer-to-Peer communication Exchange of information between two peers of signaling Layer 3 is performed by means of the three sublayer protocols CM, MM, RR. A protocol is a set of rules and formats over which the control information and user data are exchanged between the two peers. 4.3.4 Contents of signaling layer 3 related technical specifications GMR-104,008 7 specifies the protocols for CC, MM, DTRS, and RR management. GSM 04.10 lo specifies the protocols for SS support. GSM 04.1 1 1 i specifies the protocols for SMS support. 5 Structure of signaling layer 3 functions 5.1 Basic groups of functions Signaling Layer 3 contains the following groups of signaling functions: cc SMS ss support MM RR Management DTRS These functional groups are realized by separate protocol control entities: Other functions contained in Layer 3 are related to the transport of messages such as multiplexing and splitting. These functions are defined in the RR management sublayer and the MM sublayer. They route the messages according to the PD and Transaction Identifier (TI), which are included as part of the message header. The MM sublayer routing function shall route the messages of the CM entities and of the MM entity of its own sublayer in the uplink direction toward the service access point of RR. This sublayer shall also multiplex these messages for parallel transactions. The routing function of the RR management sublayer shall distribute the messages to be sent according to their PD and the actual channel configuration. The DTRS entity uses the same routing function to send messages to the RR entity to transmit DTMF tone related information. The RR entity internally checks whether a Data Link (DL) connection on SAPI = 2 on the FACCH Terminal-To- Terminal (TtT) signaling link exists for messages with PD of DTRS. If so, it transmits the information using this DL connection or it uses the SAPI = O connection (the main signaling link). The RR suppresses transmission of a message internally if there is no RR connection present or if it is at the network side of a single hop TtT call. The messages provided at the different service access points of Layer 2 in the downlink direction are split by the RR sublayer routing function according to the PD. Messages with a PD equal to RR are passed to the RR entity of their own sublayer. All other messages are provided to the DTRS/MM sublayer at the service access point RR-SAP. The DTRS entity extracts messages using its own PD and passes the remaining messages on to the MM sublayer. 4 Copyright Telecommunications Industry Association Provided by IHS under license with EIALicensee=IHS Employees/1111111001, User=Wing, Bernie Not for Resale, 03/29/2007 21:22:17 MDTNo reproduction or networking permitted without license from IHS -,-,- 5 TINEINIS-782.04007 The routing function of MM passes the messages according to the protocol discriminator (PD) and the transaction identifier (TI) towards the MM entity or towards the CM entities via the various MM-SAP'S. The message header or parts of it are not removed by the RR routing function before passing it to the MM sublayer because further routing shall be done by MM using the same criteria. This is not in line with the rules of the IS0 reference model but it reduces the number of message octets. 5.2 Pro toco I arch i tectu re A hierarchy of three sublayers is defined as follows: The RR sublayer provides services to the MM sublayer and utilizes the services of signaling Layer 2. The RR and DTRS protocol entities are included. The MM sublayer provides common services to the entities of the CM sublayer. The CM sublayer includes the CC, SS and SMS entities, which are independent entities. See figure 5-1 for Layer 3 MES side protocol architecture.
