Telephone System) protocol stacks providing the type of data
capabilities planned for "third generation" mobile
voice and data networks.
Our GPRS and UMTS protocol stacks are reliable,
efficient and are proven building blocks for deploying exceptional
GSM, GPRS and UMTS terminal products.
Aricent is the first company to offer unique Integrated
Stacks as value added software solutions for the Iu interface
of the 3G networks. The IuPS
and IuCS integrated
software products provide distributed and highly scalable
architecture offering higher reduction in time to market for
3G nodes. In addition the Aricent also provides integrated Iub,
Iur and Uu stacks. Check out the Aricent
Edge and the Common Stack
Porting Library (CSPL).
- AAL2 Signaling
Stack (ALCAP):
AAL2 signaling is the signaling protocol for dynamic establishment,
release and maintenance of AAL2 point-to-point connections
between nodes, in an AAL2 network. The AAL2 Signaling stack
from Aricent is a field proven building block for developing
telecom equipment, network components as well as applications.
- ATM SAAL
Stack:
The SAAL layer is used for reliable signaling between ATM
end points. The SAAL stack from Aricent provides efficient and
reliable solutions for signaling components.
- BSSAP+ Stack:
The BSSAP+ protocol stack from Aricent is responsible for conducting
non-GPRS procedures over the Gs interface, between the SGSN
and the VLR. The BSSAP+ protocol stack from Aricent
, has been developed for the SGSN (Serving
GPRS Support Node) side.
- CAMEL Application
Part (CAP) Stack:
The CAMEL Application Part (CAP) Stack from Aricent is a ‘state
of the art’ implementation of the CAP protocol compliant
with latest 3GPP and ETSI specifications. Aricent CAP stack
can be readily deployed in GSM, GPRS as well as 3G networks.
It provides service control for voice & data services and
IP multimedia sessions.
- Core Network
Ranap Stack:
The CN RANAP Stack protocol implementation from Aricent provides
support for all RANAP Elementary Procedures (EPs) for accomplishing
Radio Access Bearer Management, Serving RNS Relocation,
Transport of NAS Information between UE and CN, Paging UE
and Release of Iu resources.
- Framing Protocol:
Framing protocol (FP) is a user plane protocol and forms
Layer-1 of the radio network layer of access stratum in
a UMTS network. They provide an important synchronization
function between higher-layer radio access protocols (for
example RLC, MAC) and the timing requirements of the radio
transmission system.
- GPRS
Gb Interface Stack:
The GPRS Gb Interface Stack from SS has been developed for
both the SGSN and BSS/PCU nodes. The BSS - Gb product can
be used to upgrade existing GSM BSS equipment and provide
GPRS based packet data services.
- GMM and
SM Stacks:
GPRS Mobility Management and Session Management (GMM/SM)
protocol supports mobility management functionality of a
mobile such as GPRS attach, GPRS detach, security, routing
area update, location update. The main function of the SM
layer is to support PDP context handling of the user terminal.
SM comprises of procedures for the PDP context activation,
deactivation, and modification.
- GPRS
Tunneling Protocol:
The GPRS tunneling protocol (GTP) from Aricent enables communication
between GPRS support nodes in a GPRS network (both GSM phase
2+ and UMTS). GTP is defined for the Gn interface - the
interface between GSNs within a PLMN, and for the Gb interface
between GSNs in different PLMs. In addition, the GTP software
at the SGSN, provides the user data transmission on the
IuPS interface.
- IPoA:
The IPoA stack from Aricent, is a standards based software building
block for providing classic IP over ATM (CIPoA) solutions,
which can be used for building Telecom and Networking equipment
as well as applications.
- MAP:
The UMTS MAP stack from Aricent enables signaling between different
network entities such as HLR, MSC/VLR, SGSN and GGSN. This
stack is built on top of the Transaction Capabilities Applications
Part(TCAP) layer, the topmost layer of the SS7 stack.
- NBAP:
The Node B application part (NBAP) is a control plane protocol
used at the Iub interface and carries signaling traffic
to manage the logical resources at Node B. It forms the
basis for radio network control signaling between Node B
and RNC and handles all procedures between the two elements.
- PDCP:
Packet Data Convergence Protocol (PDCP) is designed to make
WCDMA protocol suitable to carry TCP/IP protocol between
UE and RNC. It maps higher-level protocol characteristics
onto the characteristics of the underlying radio-interface
protocols, providing protocol transparency for higher-layer
protocols. PDCP provides protocol control information compression.
- Radio Resource
Control Stack:
The Radio Resource Control (RRC) Stack offering from Aricent
enables OEMs to build Radio Network Controller
(RNC) nodes faster and with reduced costs. The Radio Resource
Control (RRC) layer handles the control plane signalling
of Layer 3 between the UE(s) and UTRAN.
- RLC
and MAC Protocols:
RLC and MAC protocols form data link sub-layers of the UMTS
radio interface and reside on the RNC node and the User
Equipment. Aricent provides RLC & MAC stacks as an integrated
offering and these can be further integrated with Framing
Protocol.
- RNSAP:
The RNSAP (Radio Network Subsystem Application Part) stack
by Aricent enables OEMs to build Radio
Network Controller (RNC) nodes faster and at lower cost.
RNSAP is a control plane protocol used at the Iur interface
and carries signaling traffic to manage the logical resources
at DRNS. It forms the basis for radio network control signaling
between any 2 RNC nodes and handles all procedures between
the two RNCs.
