2 shows a communication system 200 according to an embodiment of the invention.

The communication system 200 is implemented according to the UMTS architecture described by 3GPP, the integral part of which is an IMS 211 is. A communication terminal 201 is by means of an access network 202 with the IMS 211 coupled.

The access network 202 For example, a mobile radio communication network according to the UMTS standard, ie a Universal Terrestrial Access Network, the access of the communication terminal to the IMS by means of a packet-switched domain 211 However, in another embodiment, an access network according to the GSM standard, eg a GSM EDGE radio access network, may also be provided.

The access network 202 can also be a landline. For example, the communication terminal 201 have a device that allows access to the Internet, such as a DSL (Digital Subscriber Line) modem. In this example, the communication terminal is via the Internet with the IMS 211 coupled.

According to the design of the access network 202 is the communication terminal 201 For example, a mobile phone or a computer with or without a mobile module.

In this embodiment, the access network is 202 a mobile communication system according to the UMTS communication standard.

A mobile network 212 of the access network 202 shows the architecture of a UMTS radio network, also referred to as UMTS Terrestrial Radio Access Network (UTRAN).

The access network 202 has a PS domain 240 which comprises the components SGSN (Serving GPRS Support Node) and GGSN (Gateway GPRS Support Node) and the interface for packet-switched communication links between the mobile radio network 212 and external packet-based data networks, such as the Internet, and access to the IMS 211 realized.

Accordingly, the PS domain leads 240 All the functions required to ensure the transport of packet-switched data. Furthermore, it allows the transport of signaling messages to the IMS 211 ,

The access network 202 also has an HLR (Home Location Register) 241 , which is a central database in which all information is stored by subscribers (users), which are required, inter alia, for establishing a connection and for managing communication services.

By means of the access network 202 is the communication terminal 201 with a P-CSCF (CSCF: Call Session Control Function, P-CSCF: Proxy-CSCF) 203 of the IMS 211 coupled.

The P-CSCF 203 serves as a switch and is using a DNS (Domain Name Service) server 204 and an I-CSCF (Interrogating-CSCF) 205 coupled.

The I-CSCF 205 is with an HSS 206 (Home Subscriber Server) 206 and an S-CSCF (Serving CSCF) 207 coupled. The S-CSCF 207 is coupled to a plurality of application servers (AS, Application Server), of which only one application server 238 is shown. The S-CSCF 207 is also equipped with an MRFC (Media Resource Function Controller) 242 coupled.

The communication terminal 201 , the access network 202 , the P-CSCF 203 and the DNS 204 are tei le of the visited network (V-PLMN) 209 , The I-CSCF 205 , the HSS 206 , the S-CSCF 207 and the application server AS 238 are parts of the home communications network (H-PLMN) 208 , The P-CSCF 203 , the I-CSCF 205 , the HSS 206 and the S-CSCF 207 are part of the IMS (IP Multimedia Core Network Subsystem) 211 ,

By means of the communication terminal 201 a user can use the communication services of the IMS 211 use, for example, an "instant message" to another with the communication system 200 send a paired communication terminal or conference with users of others with the communication system 200 perform coupled communication terminals.

Before the user of the communication terminal 201 Communication services using the IMS 211 can use (and for example by means of the IMS 211 is reachable), it is necessary that the user in the IMS 211 More specifically, an S-CSCS 207 , registered. The registration is not permanently valid, but only for a certain period of time. The user must renew the registration before the end of this period (re-registration), otherwise the user is deregistered. The user can, however, after a deregistration at any time back in the IMS 211 to register.

It can be provided, for example, that the communication terminal 201 automatically performs a registration when it is turned on.

A user (or the communication terminal he uses) may subscribe to one or more public user identifications in the IMS 211 be registered. The assignment of public user identifications to the user of the communication terminal 201 is in 3 illustrated.

3 shows an identification structure 300 according to an embodiment of the invention.

The user of the communication terminal 201 has become a user of the IMS 211 subscribed and thus corresponds to an IMS subscriptions 301 , The user is unique as an IMS Subscriber through a single Private User Identity (Private User ID) 302 characterized. Is the communication terminal 201 For example, a mobile subscriber unit according to UMTS, so is the private user identification 302 stored on the UICC (Universal Integrated Circuit Card) of the mobile subscriber unit and is used exclusively for network authentication, ie neither the user of the communication terminal 201 Any communication partners use private user identification 302 and the private user identification 302 is neither for the user of the communication terminal 201 still visible to any communication partner of the user.

• • tel:+49-89-4444@home2.de
• • sip:peter@work1.de
• • tel:+49-89-55555@work2.de

zugeordnet.The private user identification 302 are several public user identifications (Public User Identities, Public User IDs) 303 assigned. A public user ID (Public User ID) 303 is illustratively an address under which the user in the IMS 211 is reachable. In this embodiment, the user of the communication terminal 201 for example, the public user identifications

• • sip: peter@home1.de
• • tel: +49-89-4444@home2.de
• • sip: peter@work1.de
• • tel: +49-89-55555@work2.de

assigned.

A registration request of the communication terminal 201 refers only to a single public user identification 303 , For example, the communication terminal 201 by sending a registration request message to the INS 211 request that the public user identification sip: peter@home1.de in the IMS 211 is registered. The registration request message is configured, for example, according to the SIP format as follows:

The registration of the public user identification sip: peter@home1.de in the INS 211 has the effect that for the next 3600 seconds (this time period is indicated by the string "Expires = 3600" in line 5) all communication request messages sent to the INS 211 with the address sip: peter@home1.de be sent to the communication terminal 201 to get redirected.

In response to the registration request message described above, which is configured as a SIP REGISTER message as shown in this embodiment, the INS transmits 211 to the communication terminal an acknowledgment message, in this embodiment in the form of a 200 OK message according to SIP. The acknowledgment message has a P-Associated URI header in which all the users of the communication terminal 201 associated public user identifications 303 are listed, wherein the registered according to the registration request message public user identification 303 is listed first. The confirmation message is accordingly configured, for example, according to the SIP format as follows:

Several public user identifications 303 are to an identification group 304 , also referred to as Implicit Registration Set. The meaning of the identification group 304 is that, once a public user identification 303 the identification group 304 according to a registration request in the IMS 211 is registered (which is referred to as explicit registration), all other public user identifications 303 from the identification group 304 also in the IMS 211 registered (which is called implicit registration). Analogous to a (explicit) deregistration of a public user identification 303 from the identification group 304 automatically all other public user identifications 303 the identification group 304 (implicitly) deregistered.

in the Following is assumed that the public user identifications sip: peter@home1.de and tel: +49-89-4444@home2.de to a first identification group are summarized and that the public user identifications sip: peter@work1.de and tel: +49-89-55555@work2.de to a second identification group are summarized.

Implicit registration amounts are typically provided by the corresponding user at the beginning of subscribing or adding new public user identifications 303 defined for the user. The definition of implicit registration amounts is typically not with the help of the communication terminal 201 but performed for example by means of a WWW-form. In particular, in this case it is not possible to store in the communication terminal (for example by means of a UICC) which public user identifications are combined to form an identification group.

According to the IMS standard, it is provided that the communication terminal 201 after his registration in the IMS 211 subscribed to a Registration State Event Package. This subscripting has the consequence that the communication terminal 201 is informed each time when the registration status of the user of the communication terminal 201 changes.

This information is transmitted in the form of an XML document. For example, was a registration of the user of the communication terminal 201 for the public user identification sip: peter@home1.de and sip: peter@work1.de carried out, a corresponding information message, for example, as follows according to the SIP format configured:

Each <registration> element, starting with the string <registration> and ending with the string </ registration>, indicates the registration status for a public user identification. Since it is assumed that the user of the communication terminal 201 has requested a registration under the public user identification sip: peter@home1.de, here is the status "active", which is indicated by the character string state = "active" (see line 1 of the information message). The string aor stands for "Address of Record".

The <contact> element indicates by means of the string event = "registered" (see line 2) that the public user identification has been registered by means of an explicit registration. The <uri> element (see line 3) specifies the IP address of the communication terminal 201 ,

Since the public user identification sip: peter@home1.de and the public user identification tel: +49-89-4444@home2.de form the second identification group, the explicit identification of the public user identification sip: peter@home1.de became automatic also the public user identification tel: +49-89-4444@home2.de (implicitly) registered. The registration of the public user identification tel: +49-89-4444@home2.de is indicated by the string state = "active" (see line 6) in the corresponding <registration> element. That this is an implicit registration is indicated by the string event = "created" (see line 7), which is part of a <contact> element. Since both public user identifications identifications of the communication terminal 201 are the same, the IP address contained in the <contact> element (see the <uri> element in line 8) is the same.

Analogously, in the information message, the registration status is indicated by the public user identification sip: peter@work1.de and the public user identification tel: +49-89-55555@work2.de, which are combined to form the second identification group. The two public user identifications are registered, as indicated by the strings state = "active" in line 12 and line 16. The public user identification sip: peter@work1.de was explicitly registered, which is indicated by the string event = "registered" in line 12. The public user ID tel: +49-89-55555@work2.de has been implicitly registered, which is indicated by the string event = "created" in line 17 is shown. The same <uri> elements always return the same IP address.

By means of the confirmation message, the IMS 211 in response to a registration request of the communication terminal 201 to the communication terminal 201 transmitted as well as by means of an information message, which as part of the registration status event packet subscribing to the communication terminal 201 is transmitted, the communication terminal 201 Information about which public user IDs of the user of the communication terminal 201 to an identification group (Implicit Registration Set) are summarized.

For example, in the confirmation message transmitted to the communication terminal in response to a registration request, the public user identifications listed in the P-Associated URI header may each be assigned an identification group indication (irs -id) indicating which identification group the respective public user identification belongs to. For example, the confirmation message is designed according to the SIP format as follows (the differences from the confirmation message described above are shown in bold):

By means of the identification group information, the communication terminal 201 clearly identify which of the public user identifications are grouped into a common identification group.

Analogously, in an information message that is part of the registration status event packet subscribing to the communication terminal 201 to the communication terminal 201 is transmitted, each of the public user identifications be provided with an identification group indication. An information message is accordingly designed, for example, as follows in accordance with the SIP format:

The changes to the information message described above are also shown in bold. Also in this case, the communication terminal 201 associate each public user identification with an identification group, ie, determine which of the public user identifications are grouped into an identification group.

The entity, the confirmation message or the information message with the information about which public user identifications are combined to form an identification group, to the communication terminal 201 is, for example, the S-CSCF 207 ,

In another embodiment will not be the confirmation message or the information message for transmitting the information to the communication terminal, which public User identifications grouped into one identification group are used, but it will be a specially designed collection message transmitted with this information to the communication terminal.

In summary, in one embodiment, a message generator is provided which generates a message for transmission to a communication terminal, wherein the communication terminal is associated with a plurality of identifications, among which the communication terminal may be registered in a communication network, wherein a plurality of identifications of the plurality of Identifications are combined into one identification group, and wherein, when the communication terminal is registered under an identification of the identification group in the communication network, it is also registered among the other identifications of the identification group in the communication network. The message contains the information as to which identifications of the plurality of identifications are part of the identification group.

In another embodiment a message generator is provided which is a message for transmission to a communication terminal generated, wherein the communication terminal a plurality of identifications are assigned, under which the communication terminal in a IMS can be registered, with multiple identifications of the plurality from identifications to an identification group are and wherein when the communication terminal under an identification of the ID group in which IMS is registered, it also under the other identifications of the identification group in the IMS is registered. The message contains the information which Identifications of the plurality of identifications Part of the identification group are.

In another embodiment a registration server computer is provided that has a registration request a communication terminal receives wherein the communication terminal a plurality of identifications are assigned, among which the communication terminal may be registered with the registration server computer, where multiple identifications of the plurality of identifications to one Identification group are summarized and where, if that communication terminal under identification of the identification group at the registration server computer is registered, it also among the other identifications of Identification group is registered with the registration server machine. The registration server generates a message with the information which identifications of the plurality of identifications are part of Identification group are.

In a further embodiment a message generator is provided which is a Message for transmission to a communication terminal generated, wherein the communication terminal a plurality of identifications are assigned, among which the communication terminal in a communication network can be registered, with multiple identifications of the plurality from identifications to an identification group are and wherein when the communication terminal under an identification the identification group in the communication network deregistered It will also be among the other identifications of the identification group in the communication network is deregistered. The message contains the information, which identifications of the plurality of identifications Part of the identification group.
