Why secondary pdp

There is no default form of the command. Two new disconnect reasons have been introduced: sgsn-nrspca-actv-rej-by-ms MS sends a Request Secondary PDP Context Activation Reject message sgsn-nrspca-actv-rej-by-sgsn For all other cases where NRSPCA context activation does not complete successfully Additional counters have been added to session management statistics in the output of the show gmm-sm statistics command to represent the session management messages used by NRSPCA.

Similarly, counters have been added to the tunnel management statistics in the output of the show sgtpc statistics command. These counters are described in the next section. For NRSPCA activation failures, the Abort statistics in the verbose mode of the show gmm-sm statistics or show gmm-sm statistics sm-only command outputs provide reasons for the failure.

The various counters are described in next section. Note that network initiated flag is present in only a few dictionaries, such custom24, custom13, and custom6. Table 4. Table 5.

If it is configured to None and the UE requested QOS parameters are valid, the test set will use the requested QoS, otherwise the test set will use the default value s in the accept message. You are not allowed to change these settings while in Active Cell operating mode and the data status is other than Idle. This setting should be larger than the Guaranteed Bitrate for Uplink. The process may be described as follows: referring to FIG.

Now referring to FIG. The embodiment of the present invention shown in FIGS. However, in an alternative embodiment it is possible to include a filter function or configuration in for instance a Traffic Flow Template, TFT for redirecting the data packets at the GGSN level for instance as part of the request for creation of the secondary PDP context; the same signaling process is used as described in FIGS.

This embodiment is illustrated in FIGS. One aspect that one may want to consider is how to handle billing matters in the two above described embodiments. In the first embodiment, the GGSN does not know which way the packet actually has been directed and therefore data packets may be booked for using other resources than what actually was used.

This may lead to that a user would be charged for resources not used or with a wrong price. In the second embodiment using the filter the GGSN knows which resources the data packets have used and therefore the billing aspects of the communication may be solved. Turning now to FIG. The service node may further comprise a second interface and a second communication interface More communication interfaces and may be provided as well depending on the configuration of the support node. The computational unit is arranged to send request for PDP context creations and amending such messages in order to control the data packet flow.

The storage unit is arranged to store programs and data flow data running in the computational unit The interfaces and are arranged to handle communication between the computational unit and respective communication interface and The present invention is advantageously implemented in the SGSN. The present invention is conveniently solved in software stored in a computer readable medium at any suitable location for use in the telecommunications infrastructure network.

However, it should be understood that it may also be implemented as hardware in part. The TS Otherwise a TFT is provided. The TFT contains attributes that specify an IP header filter that is used to direct data packets received from the interconnected packet data network to the newly activated PDP context.

QoS Requested indicates the desired QoS profile. Request using the Tl indicated by Linked Tl. UE see GSM These procedures are defined in TS The contents of these documents are incorporated by reference herein.

It is another aspect of the present invention to reduce and possibly eliminate this SM signaling to further decrease the setup time needed to establish the packet-based bearers which in turn reduces the IMS Session.

Setup time. These needs and other needs are satisfied by the present invention. In yet another embodiment, the method minimizes the setup time for establishing IMS telephony using pre-provisioned radio resources-reserve according to most demanding codec.

FIGURE 9 is a step-by-step flow diagram used to help describe a method that can be used to establish a media flow between two GPRS UEs in accordance with a third embodiment of the present invention; and FIGURE 10 is a step-by-step flow diagram used to help describe a method that can be used to establish a media flow between two GPRS UEs in accordance with a fourth embodiment of the present invention. IMS Session and there are several ways this can be done.

Second, the present invention introduces several different methods that can be used to minimize end-to-end signaling between two devices e. The steps are as follows:. For example, the implicit context activation can be triggered by application level signaling or by the reception of an Activate Secondary PDP Context Accept message see step 6.

The message also indicates BearerCharacteristics e. QoS required for the service and information needed to create a TFT. These CtxtlD parameters if. The contents of TR This message includes the required bearer characteristics.

This message may also indicate the piggy-backed values for one or more of the CtxtlD parameters. In this case, the Tl should be identical to the Tl value allocated for the context activated through the procedure. However, the messages in steps 2, 4, 7 and 8 are not used in the current 3GPP standard.

As a result, the names of these messages will likely be different when the present invention becomes a standard. For example, the implicit context activation can be triggered by application level signaling or by the reception of a RB Setup Response message see step 7. But, the. However, the QoS Req could be set using anyone of a wide variety of ways.

However, the messages in steps 2, 4, 1 1 and 12 are not used in the current 3GPP standard. And, then the originating network initiates the resource reservation so the media flow can be established between UE 1 and UE 2. The steps in this flow are as follows:.

In this flow, the context information parameters were assumed to be pre-defined in the 3GPP standard. The UE 2 can at this point alert its user. And, the network needs to know if the UE expects the network to request the activation or if it will do it on its own initiative. It is important that both the UE and network know what is expected of them and what they can expect. Because, if this information is not known, then the UE and network might try to activate one context each for the same media flow.
