`ABSTRACT
`(57)
`The invention provides a method and device which may per(cid:173)
`form a combined attach and communication connection
`establishment procedure when attaching an equipment such
`as a mobile station to a mobile communication network. An
`attach request sent form the equipment may initiate this com(cid:173)
`bined attach and communication connection establishment
`process. In the Home Location Register, communication con(cid:173)
`nection parameters are set as default values which may be
`automatically selected, for instance when receiving a com(cid:173)
`bined attach and communication connection establishment
`request. The combined attach and communication connection
`establishment process reduces the signaling load in the net(cid:173)
`work and speeds up communication connection establish(cid:173)
`ment.

`
`When a user equipment is newly attached to a wireless
`communication network for receiving and/or originating
`calls, data transmissions or the like, an attachment process for
`attaching the user equipment to the wireless communication
`network is necessary. When a subscriber is then intending to
`originate or receive a message or a call, an additional com(cid:173)
`munication channel establishment process may be necessary.
`For instance, in a GSM system (Global System for Mobile
`Communications) such as a packet switched service, for
`instance GPRS (General Packet Radio Service), or in a 35
`UMTS system (Universal Mobile Telecommunications Sys(cid:173)
`tem), the user equipment exchanges a signalling flow with its
`associated node for establishing a communication channel,
`for instance a PDP (Packet Data Protocol) context or the like.
`This signalling leads to an additional load on the network and 40
`may additionally result in a certain brief delay before actually
`being able to start the transmission or reception.
`
`SUMMARY OF THE INVENTION
`
`Certain embodiments of the present invention relate to an
`apparatus configured to send or receive an attach request to a
`network, wherein the attach request is configured to trigger a
`create communication connection default procedure with a
`gateway device. The apparatus is further configured to send or
`receive a radio bearer establishment request. The apparatus is
`also configured to generate or receive a bearer establishment
`response.
`In other implementations, another embodiment of the
`present invention relates to an apparatus configured to send an
`attach request for attaching a mobile device to a network.
`Specifically, the attach request is configured to enable gen(cid:173)
`eration of a create default communication connection request
`for retrieving default data defining a packet data protocol in
`response to receiving the attachment request. Also, the attach
`request is further configured to enable activation of a packet
`data protocol context using the default data.
`In other embodiments of the present invention, an appara(cid:173)
`tus is configured to send an attach request for attaching a
`mobile device to a network. The attach request is configured
`to be received by a network element and to enable the network
`element to trigger a create communication connection default
`
`DETAILED DESCRIPTION OF PREFERRED
`EMBODIMENTS OF THE INVENTION
`
`FIG. 1 illustrates the basic layout of a part of a wireless
`communication network (for instance a PLMN) which here is
`implemented as a GPRS system. A mobile station (MS) 1
`45 communicates with a Serving GPRS Support Node (SGSN)
`2. The system comprises at least one Home Location Register
`(HLR) 3, at least one Gateway GPRS Support Node (GGSN)
`4 and an Equipment Identification Register (EIR) 5. The parts
`may communicate with each other as indicated by the arrows
`50 shown in FIG. 1. The system will normally contain a plurality
`of mobile stations or other user equipments 1 although only
`one mobile station is shown in FIG. 1. Likewise, a plurality of
`support nodes 2 is provided which support the mobile stations
`or other user equipments located within the area covered by
`55 the support node. This structure as well as the normal signal(cid:173)
`ing and information flow between the components of the
`wireless communication network is known and will therefore
`not be described in greater detail.
`FIG. 2 schematically illustrates part of the storage contents
`60 of a home location register 3. The register 3 stores, for each
`subscriber, or each group of subscribers, or at least for some
`of the subscribers or groups, at least one communication
`connection ( e.g. channel) information set which here is des(cid:173)
`ignated as PDP context information, one of which is set as
`65 default value and is automatically selected when not receiv(cid:173)
`ing any specific selecting request pointing to a different PDP
`context information. The register (HLR) 3 includes subscrip-

`3
`tion information and then information about the PDP contexts
`of the subscriber. One or many of the PDP contexts may be set
`as default.
`In the present embodiment, for each subscriber, or at least
`some of the subscribers, three different PDP context informa(cid:173)
`tion sets (for PDP context activation or creation, or the like) 6,
`7, 8 are respectively stored, wherein context information 1
`(reference numeral 6) is set as default value. The context
`information "Context 2", reference numeral 7, and "Context
`3", reference numeral 8, are deliberately selectable by a sub(cid:173)
`scriber when requested by the subscriber. The database of
`register 3 contains such triplets of information for each sub(cid:173)
`scriber or at least for some of the subscribers or a group of
`subscribers. Of course, the number of alternative PDP context
`information sets may be varied according to design and need
`and may range from only one (default value only) to two,
`three or more selectively selectable information.
`Generally, before the mobile station 1 is able to send or
`receive information, it must first perform an attach proceed(cid:173)
`ings, for instance after switching it on. In addition, in some
`services such as packet data switching oriented networks, for
`instance GPRS or UMTS, an additional communication
`channel establishment procedure will normally be carried out
`which is called PDP context activation ( or creation) in GPRS
`or UMTS. According to the present invention, the attach and
`POP context activation processes are combined. The mobile
`stations can therefore perform a combined attach and default
`PDP context activation which decreases signaling in the radio
`interface (air-interface).
`This combined attach and communication channel estab- 30
`lishment procedure is shown in FIGS. 4 and 5. The default
`POP context or contexts is (are) activated according to the
`subscription-based information stored in the register 3, that is
`based on "Context 1" information, reference numeral 6. If
`requested by the subscription of one or more subscribers, 35
`multiple default PDP contexts are allowed.
`The quality of service (QoS) of the default PDP context is
`preferably such that the mobile station 1 is only charged if
`data is transferred or received on the default POP context, but
`no time-based charging is performed for the default PDP 40
`context alone. The quality of service of the default POP
`context will be decided based on the subscription and will be
`a default value unless otherwise prescribed. If a specific qual-
`ity of service is desired, the subscriber will then have to select
`one of the different context information such as 7, or 8, 45
`provided same define an appropriate QoS (Quality of Ser(cid:173)
`vice).
`Subscribers mainly using the packet switched service (for
`instance GPRS or UMTS) for transferring voice, are allowed
`to define the QoS of the default POP context appropriately.
`FIG. 3 shows part of an Attach request 9 which is sent from
`the mobile station 1 to the support node 2 for initiating the
`attach procedure, which is, in the present invention, a com(cid:173)
`bined attach and POP context activation request. The Attach
`request 9 comprises a data field 10 defining IMSI (Interna- 55
`tional Mobile Subscriber Identifier) or, if available, P-TMSI
`and RAI (Routing Area Identity). The "Attach Type" field 11
`of the Attach request 9 indicates which type of attach is to be
`performed which may basically be "GPRS attach only",
`"GPRS attach while already IMSI attached", "combined 60
`GPRS/IMSI attach" or, as indicated in FIG. 3, combined "PS
`(packet switched)+default POP context activation".
`In case the attach request transmitted from the mobile
`station 1 specifies the attach type "PS+DEFAULT PDP CON(cid:173)
`TEXT ACTIVATION" as shown in FIG. 3, the system is 65
`informed on the desired combined attach and PDP context
`activation. The support node 2 then not only performs a
`
`4
`"packet switched" attach but is furthermore adapted so as to
`automatically initiate, when receiving this request and having
`the attachment effected, a default POP context activation
`without necessity for the mobile station 1 to send any addi-
`tional command.
`The attach request 9 contains further fields such as "ORX
`parameters" which are not shown in FIG. 3 and are in accor(cid:173)
`dance with the customary specification of attach requests, see
`the respective standards. The attach request 9 differs from
`10 these standards only in so far as it is now possible to indicate,
`in field 11, a combined attach and communication channel
`establishment process such as "attach and default POP con(cid:173)
`text activation".
`FIG. 4 shows an attach process flow. In step Sl, the mobile
`15 station 1 sends an Attach request to the support node 2 which
`then checks, in step S2, the received Attach request so as to
`detect whether a normal attach such as a "packet switched"
`attach is requested, or a combined attach and default POP
`context activation request is transmitted. This check is per-
`20 formed by examining the data field 11 of the Attach request 9
`specifying the desired attach type. When combined attach and
`default POP activation request is received by the support node
`2, same is adapted to address the Home Location Register 3,
`and to read ( or receive) the subscriber information including
`25 the default PDP context information stored therein. All the
`subscription information if transferred from the HLR to the
`SGSN. In step S4, the system then performs an attachment as
`well as one or many PDP context activations depending on the
`read default POP context information.
`If no combined attach and default POP activation request is
`detected in step S2, the process proceeds to step S5 and
`performs a normal attachment only according to the desig(cid:173)
`nated attach type. As part of steps S4, S5, the support node 2
`may also send an Attach Accept message to the mobile station
`1 for informing same on the effected attachment. The attach
`process then ends (step S6).
`FIG. 5 shows the combined attach and POP context acti(cid:173)
`vation in greater detail.
`In step 1., the mobile station 1 initiates an attach and default
`POP context activation by sending an Attach Request as
`shown in FIG. 3. The Attach Type parameter 11 indicates that
`combined attach and default POP context activation is
`required. In the present case, the Attach Request is sent
`because the mobile station 1 has switched on. In step 2., the
`new support node 2 (new SGSN) sends an Identification
`Request to the old support node ( old SGSN) which responds
`with an Identification Response defining the IMSI of the
`mobile station 1. If the mobile station 1 should be unknown in
`both the old and new SGSN, the new support node sends an
`50 Identity Request to the mobile station 1 (step 3.) which trans(cid:173)
`mits an Identity Response indicating its IMSI. In step 4., an
`authentication may be performed. Further, in step 5., an
`equipment checking ("IMSI check; IMSI=International
`Equipment Identification") may be performed by addressing
`the Equipment Identification Register (EIR) 5.
`In step 6., the support node 2 informs the Home Location
`Register 3 on the new location in case the support node
`number has changed since the GPRS detach, or it Is the very
`first attach. The old support node is requested to cancel the
`location which is acknowledged by sending back an Cancel
`Location Acknowledgment.
`Further, the Home Location Register 3 sends an Insert
`Subscriber Data to the new support node 2 which subscriber
`data includes information on the default PDP context(s ). The
`new support node validates the MS' s presence in the new
`routing area, and sends back an Insert Subscriber Data
`Acknowledgement to the Home Location Register 3. Further-

`

`more, the Home Location Register 3 sends back, as part of
`step 6, an Update Location Acknowledgement message.
`In step 7 ., RAB assignment procedure is performed for the
`default PDP context( s) according to the information received
`from the Home Location Register 3 in step 6. This is a pre-
`ferred implementation of the invention. The procedure con(cid:173)
`sists in sending a RIB Assignment Request from the new
`support node 2 to the radio access network RAN transmitting/
`receiving the radio waves to/from the mobile station 1, setting
`up the radio bearer between the radio access network RAN 10
`and MS (by sending a Radio Bearer Setup and a Radio Bearer
`Setup Complete, and finally sending a RIB Assignment
`Response.
`In the next step 8, the new support node 2 sends a Create 15
`PDP Context Request to the gateway support node 4 so that
`the default PDP context(s) is (are) activated in the support
`node(s) 4 according to the information received from the
`Home Location Register 3 in step 6. In step 9, the support
`node 2 sends an Attach Accept message to the mobile station 20
`1 for acknowledging the attach and default PDP context acti(cid:173)
`vation. The attached accept message may include information
`about the activated PDP context( s). The mo bile station 1 may
`acknowledge the parameters sent by the support node 2, by
`sending an Attach Complete message in step 10. However, 25
`step 10 may also be omitted.
`Steps 7 and 8 are performed N times, N representing the
`number of default POP contexts.
`According to the invention, the combined attach and
`default POP context activation is therefore performed by 30
`storing default POP context information in a register such as
`a Home Location Register, and by activating the default PDP
`context(s) according to the subscriber-based information
`stored in the register. The quality of service (QoS) of the
`default PDP context( s) may be fixed but may also be decided
`based on the subscription.
`A basic idea is to activate default POP context(s) according
`to the subscription information received from the HLR. As an
`alternative, the mobile station MS may send some parameters
`for the default POP context(s) and the HLR completes the 40
`missing parameters. As an example, APN (Access Point
`Name) may be sent from MS, and QoS from HLR.
`The PDP context activations) is (are) therefore automati(cid:173)
`cally performed based on the HLR subscription. This leads to
`a reduction of the signalling in the radio interface, without 45
`creating any limitations on the network and its use. Further(cid:173)
`more, it is not necessary, for PDP context activation, to send
`a QoS field and/or APN from the mobile station 1 to support
`node 2 or 3, because the Home Location Register has one or
`more special contexts which are marked as default contexts 50
`and are automatically selected. This possibility of setting
`default contexts in the Home Location Register has also
`advantages with regard to more advanced services such as
`UMTS services wherein the users are likely to have more than
`one subscribed context, which accordingly define different 55
`session handling parameters.
`FIG. 6 illustrates a further embodiment.
`In the first embodiment shown in FIGS. 1 to 5, the default
`PDP context( s) are automatically activated at PS attach. In the
`embodiment of FIG. 6, the MS first performs a PS attach and
`then afterwards indicates that the default PDP context(s)
`should be activated. In both cases, the default PDP context
`information comes from the HLR.
`According to the embodiments, default contexts are pro(cid:173)
`vided also in cases where a normal procedure (attach being 65
`performed with a subsequent PDP context activation upon
`request) does not apply.
`
`6
`In the following, the steps shown in FIG. 6 will be
`described in more detail with reference to the step numbering
`of FIG. 6:
`Step 1. PS (Packet-Switched) attach is performed (e.g. as
`described in 3GPP TSG 23.060).
`Step 2. The MS sends a request to activate default PDP
`context(s) to the SGSN.
`Step 3. The SGSN initiates the activation of the default
`PDP context(s) as indicated in the subscription information
`received from the HLR at PS attach ( step 1 ). The radio access
`bearer establishment procedure may be performed.
`Step 4. The SGSN sends the Create PDP Context Request
`message to the GGSN for each default POP context. The
`GGSN creates the POP context and acknowledges by sending
`the Create PDP Context Response message to the SGSN.
`Step 5. The SGSN acknowledges the activation of the
`default PDP context(s) by sending a response to the MS.
`The response may include information about the activated
`POP context(s).
`Although specific embodiments have been described
`above, the invention is also applicable with regard to other
`types of communication networks such as fixed or circuit(cid:173)
`switched networks.
`
`What is claimed is:
`1. An apparatus, comprising:
`a user equipment, the user equipment being configured to:
`send an attach request to a network, wherein the attach
`request is configured to trigger a create communica(cid:173)
`tion connection default procedure with a gateway
`device,
`receive a radio bearer establishment request, and
