Dear Edgar, The document you attached is a contribution from Lucent, comparing two alternatives (proposed by Ericsson and Alcatel) for CS terminal support in an "all IP" architecture. I did not quite catch the commonality between this discussion and what's happening in TIPHON. (I may miss something, in that case can you kelp?) Also this document was not about IN and IP. (what it said is that IP based MSC can re-use IN platform easily). Would you shed some light on your proposed IN for IP mobility?

Megaco/H.248 Contexts and Context Parameters
by Tom-PT Taylor 12 Sep '99

12 Sep '99

We have had a long discussion on the Megaco list about whether the sort of topology micro-management proposed in Berlin, with "Topology" as a context property, is really necessary. I would summarize the outcome of that discussion by saying that we can meet the known requirements for Legal Interception (if a vendor chooses to implement it in the MG) without the proposed Topology property. However, that property could allow for some value-added capability in a gateway (e.g. the difference between the subject of an operator intervention hearing only the operator and hearing the operator and also the other parties to the call in the background). I therefore propose this as the consensus resolution: the Topology property will be defined in the protocol, but support is optional both at the MG and the MGC. With this resolution in mind, I propose a change in the opening paragraph of section 6.1, "Contexts", of the current draft. It currently reads: "A Context is an association between a number of Terminations. The Context describes the topology (who hears/sees whom) and the media mixing and/or switching parameters if more than two Terminations are involved in the association." I propose instead this more expanded description: "A Context is an association ... Terminations. When more than two Terminations are present in a Context, the Context takes on the properties of a mixing bridge. The default assumption for audio streams is that the Context serves as an N-1 additive bridge, passing to each Termination the sum of inputs from all other Terminations in the context. When other media or other types of mixing are desired, the mixing behaviour for each stream must be stated explicitly as a context parameter. "By default, the Context is assumed to implement a star topology with the mixing bridge at the centre. The topology of the media flows through the context is controlled by controlling the flows into and out of the context at the individual Termination level. The flows between the Terminations and the mixing bridge are assumed to be continuations of the external flows in each direction. "As a value-added option, some MGs may support an alternate mesh topology through the mixing bridge. To control this, the protocol provides for a Topology property at the context level. Support of this property is optional at both the MG and the MGC." ------------- Following on from that, we need help from the specialists in Study Group 16, to create the appropriate syntax, first to describe the bridging properties and secondly to describe the topology. I will remind people proposing the syntax that the bridging behaviour will generally be different for each medium, and hence must be tied to the StreamID.

Introducing: Dr As Cellulite Reducing & Weight Loss System
by Andy 12 Sep '99

12 Sep '99

Hello, We work with a weight loss physician (also American Board Certified in Family Medicine), who has formulated a topical gel product that has been very successful in the elimination of cellulite fat. This cellulite-reducing topical gel product is simply amazing! You literally have to measure yourself before and after using this product to believe it. Testimonials are flooding into this physician s office from people who have lost both inches and pounds, after just the first week of using the system. Here is just one of them: "I lost nine and half inches total, after my very first week of applying the gels. After my second and third weeks of application, I lost an additional 18 inches. My inches loss, as well as my weight loss, accelerated tremendously, when I started using the weight loss pills that came in my pak. In three months, I have lost a total of 42 inches and 22 pounds! Whats more, I have more energy than ever, I sleep better and I feel so much healthier. Presently, my friends, having seen the great results I have had with Dr As Cellulite Reducing & Weight Loss System, are now using the system as well. One of them lost an astounding 18 inches total after her very first week of applying the gels. Her self esteem is so much improved. Need we say more? If you will like to receive FREE info about Dr As Cellulite Reducing & Weight Loss System, fill the Info Request Form below, and fax it to: 208-246-1506 Info Request Form: Yes, please send me the FREE info on Dr As Cellulite Reducing & Weight Loss System.

Dear Jin, You asked following question: > If we are going to describe a complete wireless access system, what are the > problems/weakness of the being-defined 3G systems we are going to > address/attack. At the time I did not have the information to reply. But since then I gotten some contributions that are going into the next 3GPP-2000 meeting and with some proposals I can agree on. The main issue I saw from most of the contributions is that everything is centered on the SGSN. I send a comment to 3GPP-2000 suggesting the following. I mean if we can do IN on IP why not Mobility on the same IP network??

I can not attack something is being-defined, If it isn't defined. If it is defined to do something and it does it, that's fine. Lets defined wireless VoIP and address and attack those areas. Which is what TIPHON and SG16 is doing...all end-to-end IP issues. It is easier to be backward comparable them forward comparable. e.g., old Rotary phones can not outpluse DTMF and New DTMF phones can do both. Both types of phones are still supported but the old Analog systems are gone, and so are the Adjuncts (today it is called the overlay solutation). Lets focus on IP. If the Radio Access interface has the option to support a pure VoIP connection. The underline pure IP (pIP) Network will need to support what TIPHON is working on now, which is : charging/billing and security, call control procedures, naming and address translation issues, end to end quality of service aspects, verification, demonstration of legacy system interworking.

If you imply that UMTS directly supports the H.323 Gateway, Gatekeeper MCU, SGW and MGW and both wireless/fixed H.323 PC terminals. Great I'll support it. Can you provide us reference to your claims. Also note that wireless mobility for a H.323 fixed terminals does not include handover, but for H.323 mobile terminal (MT) handover is included. Second point to your question, It would be nice to know what legacy NETWORK(s) is 3GPP-3GIP interworking with, since the voice and data is spit at the RAN where the voice traffic goes to the MSC and the data goes to the GPRS network. You call that alot of progresses? smells like adjuncts..

An network that is all IP end-to-end as for your example (Applications/GTP/IP). Like TIPHON system with molitity is a pure IP solution.

Implementers Guide; Changes to h.341 MIB
by Irina Suconick 10 Sep '99

10 Sep '99

Paul, Please include the following changes to H.341 MIB in the H.323 Implementers Guide. These changes were approved in the last SG16 meeting in Berlin. Thanks, Irina 1) Removed a double definition of rasAdmissionCallIdentifier from this table. rasAdmissionTable OBJECT-TYPE SYNTAX SEQUENCE OF RasAdmissionTableEntry MAX-ACCESS not-accessible STATUS current DESCRIPTION "This table contains information about entities that have been admitted by the gatekeeper. It is a list of admitted endpoints. The number of entries equals to the number of admitted endpoints." ::= { rasAdmission 1 } rasAdmissionTableEntry OBJECT-TYPE SYNTAX RasAdmissionTableEntry MAX-ACCESS not-accessible STATUS current DESCRIPTION "It contains objects that describe endpoints that are admitted by the gatekeeper. " INDEX { ifIndex, rasAdmissionSrcCallSignallingAddress, rasAdmissionRasAddress, rasAdmissionCallIdentifier } ::= { rasAdmissionTable 1 } RasAdmissionTableEntry ::= SEQUENCE { rasAdmissionSrcCallSignallingAddressTag MmTAddressTag, rasAdmissionSrcCallSignallingAddress TAddress, rasAdmissionDestCallSignallingAddressTag MmTAddressTag, rasAdmissionDestCallSignallingAddress TAddress, rasAdmissionCallIdentifier MmGlobalIdentifier, rasAdmissionConferenceId MmGlobalIdentifier, rasAdmissionRasAddressTag MmTAddressTag, rasAdmissionRasAddress TAddress, rasAdmissionCRV MmH225Crv, rasAdmissionIsGatekeeper TruthValue, rasAdmissionSrcAliasAddressTag MmAliasTag, rasAdmissionSrcAliasAddress MmAliasAddress, rasAdmissionDestAliasAddressTag MmAliasTag, rasAdmissionDestAliasAddress MmAliasAddress, rasAdmissionAnswerCallIndicator INTEGER, rasAdmissionTime DateAndTime, rasAdmissionEndpointId MmEndpointID, rasAdmissionBandwidth Integer32, rasAdmissionIRRFrequency Integer32, rasAdmissionCallType MmCallType, rasAdmissionCallModel INTEGER, rasAdmissionSrcHandlesBandwidth TruthValue, rasAdmissionDestHandlesBandwidth TruthValue, rasAdmissionSecurity TruthValue, rasAdmissionSrcWillSupplyUUIE TruthValue, rasAdmissionDestWillSupplyUUIE TruthValue, rasAdmissionTableRowStatus RowStatus } 2) Combined the two counters for each variable into one. Each variable had a counter for the number of "In" messages (received) and the number of "Out" messages (sent). Now each variable represents the number of messages that were sent and received. CallSignalStatsEntry::= SEQUENCE { callSignalStatsCallConnections Counter32, callSignalStatsAlertingMsgs Counter32, callSignalStatsCallProceedings Counter32, callSignalStatsSetupMsgs Counter32, callSignalStatsSetupAckMsgs Counter32, callSignalStatsProgressMsgs Counter32, callSignalStatsReleaseCompleteMsgs Counter32, callSignalStatsStatusMsgs Counter32, callSignalStatsStatusInquiryMsgs Counter32, callSignalStatsFacilityMsgs Counter32, callSignalStatsInfoMsgs Counter32, callSignalStatsNotifyMsgs Counter32, callSignalStatsAverageCallDuration Integer32 } 3) rasRegistrationEndpointType is changed from Integer32 to MmH323EndpointType RasRegistrationTableEntry ::= SEQUENCE { rasRegistrationCallSignallingAddressTag MmTAddressTag, rasRegistrationCallSignallingAddress TAddress, rasRegistrationSrcRasAddressTag MmTAddressTag, rasRegistrationSrcRasAddress TAddress, rasRegistrationIsGatekeeper TruthValue, rasRegistrationGatekeeperId MmGatekeeperID, rasRegistrationEndpointId MmEndpointID, rasRegistrationEncryption TruthValue, rasRegistrationWillSupplyUUIE TruthValue, rasRegistrationIntegrityCheckValue TruthValue, rasRegistrationTableNumberOfAliases Integer32, rasRegistrationTableRowStatus RowStatus, rasRegistrationEndpointType MmH323EndpointType, rasRegistrationPregrantedARQ TruthValue, rasRegistrationIsregisteredByRRQ TruthValue }

Question about SET EndpointType
by henri.maenpaa＠NOKIA.COM 10 Sep '99

10 Sep '99

All, There seems to be redundant information in the endpointType IE concerning SETs. Hopefully this has just been left there accidentally from the earlier versions of H.225v3 drafts. Could someone clarify: First, endpointType can have set "bitmask" octet string along with terminal or gateway structures. OK. Then, if terminal was chosen for endpointType, terminalInfo specifies (again) being a SET with a boolean value. I think this should be removed. If there is some reason for including it there, then shouldn't it be included into gatewayInfo struct as well?!? -Henri Mäenpää, Nokia Wireless Business Communications
