Aricent stack solutions include leading edge GPRS
(General Packet Radio Service) and UMTS (Universal Mobile
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.
- GPRS
Gb Interface Stack:
The GPRS Gb Interface Stack 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.
- 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.
- 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.
- IuPS:
The Aricent integrated stack offering for the IuPS interface
is defined by Third Generation Partnership Project (3GPP)
for interconnection between the SGSN and the RNC network
nodes in UMTS/3G networks for carrying packet data.
- IuCS:
The Aricent integrated stack offering for the IuCS interface
complies with the Third Generation Partnership Project (3GPP)
definition for interconnection between the MSC/VLR and RNC
network nodes in UMTS/3G networks for carrying circuit switched
data.
- 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.
- BSSAP+
Stack:
The BSSAP+ protocol stack 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.
- 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.
- 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.
