Definitions
- the invention describes a method and a device for signaling an acceptance of a request for a procedure between a terminal and at least one network element of a serving communication network.
- the signaling capacity between a home network of a home network and a network element of a serving communication network is calculated according to the traffic model used during normal network operations. However, in some situations, more signaling capacity is needed, for example, in restoring a network element of a serving communication network, since the network element of the serving communication network must poll the subscriber profile data at a network element of the home communication network of a terminal.
- the restoration of the network element of a serving communication network is necessary in case of loss of user data. This may be the case, for example, software upgrade, recovery, software errors, hardware errors, changes, or software patching.
- a recovery procedure may take several hours because of the severely limited signaling capacity of a network element of the home communications network. During this time, for example, the serving GPRS support node (SGSN) has neither mobile originating nor mobile terminating services, except when the terminal has regis- tered. The long runtime of a recovery procedure also causes a much higher signaling load on the access network
- 3GPP TS 24.008 V6.5.0 2004-06
- 3GPP TS 29.002 V6.5.0 2004-03
- the signaling load between network elements of the home communications network and the serving communications network is monitored and appropriate throttle mechanisms are implemented to prevent the loss of signaling messages.
- the signaling load consists at least in part of mobility management messages.
- the Mobility Management consists at least in part of the administration of the current location information (Location Management), and the Service Profile Management (Service Profile Management) of a terminal device. the user of a terminal.
- a network element of a communication network For mobile incoming services, a network element of a communication network must know the current location or location of the user of a terminal. For this purpose, the home communication network manages the location information of a network element of a serving communication network. The network element of a serving communication network in turn manages the location information of the terminal.
- Service Profile Management For mobile outbound services, the network element of the serving communication network must know the current user service profile. For this reason, the home communication network of the terminal informs the network element of the serving communication network and transmits current service profile information.
- the management and transmission of this information is done with various mobility management protocol messages or. Signaling messages.
- An overload indication towards the access network would also not be a suitable means to reduce the re-registration requests of the terminal.
- the denial of re-registration requests in the access network is not suitable for ensuring the accessibility of services within an acceptable period of time after data loss due to congestion stemming from the terminal's periodically re-registration requests.
- the object of the invention is to propose an efficient and cost-effective possibility for minimizing the signaling load in a communication network.
- a core of the invention can be seen in the fact that in a request for a procedure, for example a Routing Area Update (RAU) request at SGSN (Serving GPRS Support Node) and LUP Request (Location Update Request) at the MSC (Mobile Switching Center), a connection procedure (ATTACH), a re-registration procedure, etc., from the terminal to a network element of a serving communication network, for example a switching unit, an operator GPRS support node, etc .
- the at least one service profile information could also be requested from a network element of another serving communication network, for example at the switching unit or at the operator GPRS support node in which the terminal had previously been registered.
- the network element of the serving communication network sends the terminal at least one signaling message, which causes no further signaling messages for the requested procedure to the Network element of the serving communication network are provided by the terminal.
- the terminal is of the opinion that the request for a procedure has been accepted by the network element of the serving communication network, and thus no further requests are necessary for this procedure.
- the method according to the invention is independent of the type of signaling message.
- the communications network can be a cellular mobile radio network, an IP network or a similar communications network.
- the terminal may be a mobile terminal, a mobile computer, a mobile organizer, a computer or similar terminal.
- the invention also contemplates the decoupling of the mobility management procedures between the terminal and the network element of a serving communication network from the mobility management procedures between the network element of a serving communication network and a network element of the home communication network.
- the network element of the nenden communication network can in a further embodiment of the invention in, for example, the registration of a terminal in overload situations regardless of mobility management information from the network element of the home communication network of the terminal, a request from the terminal immediately after receiving the request with any security - Procedures etc. get answered.
- TMSI Packet Temporary Mobile Subscriber Identities
- the identification, the security procedures, the location update, the insertion of the user data in, for example, the Visitor Location Register (VLR) can then be done on the basis of, for example, a later service request of the terminal.
- the use of the P-TMSI identity of a terminal at the serving GPRS support node (SGSN) is described, for example, in the 3GPP TS 23.003 V6.3.0 (2004 -06) (3rd Generation Partnership Project; Technical Specification Group Core Network; Numbering, Addressing and identification (Release 6)), and the F-TLLI / P-TLLI identities are known, for example, from the 3GPP TS 23.060 V6.5.0 (2004-06) (3rd Generation Partnership Project; Technical Specification Group Services and System Aspects; General Packet Radio Service (GPRS); Service description; Stage 2 (Release 6)).
- the network element of the serving communication network can thus control the communication network according to the invention and provide services despite an overload situation.
- standard user profiles which are present or stored in the network element of the serving communication network, so that a user is allowed access to services, even if due to, for example, an overload situation no service profile information for the network element of the available communication network.
- a major advantage of the invention is that it can cost effectively and efficiently reduce the congestion of a network element in a communications network. Furthermore, the method according to the invention makes it possible to control and manage the overload level at each network element of the communication network.
- FIG. 1 shows a flowchart for an example according to the invention
- FIG. 2 shows a device according to the invention.
- FIG. 1 shows a flowchart for an example according to the invention in a packet-switching domain.
- the method according to the invention is also used, for example, in network elements MSC of the second mobile radio generation or in general in network elements of a serving communications network.
- Factors for this can be high throughput costs for signaling lines, a small number of charging tickets (charging records), an insufficient network infrastructure, etc. be .
- a RAU request (Routeing Area Update - Request) is sent by the terminal MS
- the network element of a serving communication network SGSN, MSC becomes a base station subsystem after receiving the RAU request via a radio access network (BSS) RAU acceptance message sent back.
- BSS radio access network
- security functions between the terminal MS and the network element of a serving communication network can be exchanged.
- the execution decision for handling the security may be, for example, adjusted to the current traffic load level (Cl).
- the corresponding PTMSI must be known as "preliminarily used" ⁇ .
- MSC When the network element of the serving communication network SGSN, MSC receives a service call from the terminal MS, a detach request is triggered with appropriate parameters, which implies that a re-attach is needed. Only after the re-connection, the terminal MS can use certain services. In some cases, using disconnect / reconnect and service profile queries, service connections can be at least partially restored. Of course, a request from the terminal could also trigger a service profile request at the home communication network of the terminal MS. Service profiles only need to be queried if a default profile (default profile) is not used. The signaling load on the access network (Radio Access Network) BSS is not significantly higher than in normal operation.
- FIG. 2 shows a device according to the invention.
- a receiving unit E a request of a terminal MS for a procedure is made to the network element SGSN, MSC of a serving communication network (SN).
- HN home network
- AuC home network
- the terminal MS is immediately after receiving, without a request for service profile information, created a signaling message that is designed such that there are no further signaling messages regarding the procedure on the part of the terminal MS.
