     TECHNICAL FIELD 
       [0002]    This disclosure relates to providing a PLMN identifier to a node of a radio access network (RAN). 
       BACKGROUND 
       [0003]    A RAN can improve its management of radio resources by knowing services currently being used by wireless communication devices (referred to herein as “user equipment (UE)”) that are served by the RAN. In 3GPP, such a function is called SIRIG (which stands for Service identification for improved radio utilization for GERAN), where the service identification is provided to the RAN (e.g., provided to a base station of the RAN or a radio network controlling in the RAN) by a core network node (CN) comprising a Mobility Management Entity (MME) or a serving GPRS support node (SGSN). 
         [0004]    While SIRIG is currently only defined for GERANs (GSM EDGE Radio Access Networks), SIRIG can be extended to other radio access technologies (RATs), e.g., universal mobile telecommunications system (UMTS), long term evolution (LTE), etc. 
       SUMMARY

The one of the plurality of fields includes a Public Land Mobile Network (PLMN) identifier of the PGW. The method further includes the first CN forwarding the received PLMN identifier to the base station apparatus. 
         [0006]    According to another aspect of the present invention, a method in a communication system includes an SGSN, a base station serving a user equipment (UE), an RNC controlling the base station, and a packet data network gateway (PGW) associated with the UE, the method being performed by the SGSN. The method includes the SGSN obtaining a PLMN identifier (ID) of the PGW. The method further includes the SGSN transmitting the PLMN ID to the RNC. 
         [0007]    According to another aspect of the present invention, a method in a communication system includes a first core network node (CN), a base station apparatus serving a user equipment (UE), and a packet data network gateway (PGW) associated with the UE, the method being performed by the first CN. The method includes the first CN obtaining a PLMN identifier of the PGW. The method further includes the first CN transmitting a message to the base station apparatus. The message includes: (i) an information element containing the PLMN ID of the PGW; and (ii) a radio access bearer (RAB) identifier information element including data identifying a RAB. 
         [0008]    According to another aspect of the present invention, a method in a communication system includes a first core network node (CN), a second CN, and a packet data network gateway (PGW) associated with user equipment (UE). The method is performed by the first CN and includes the first CN encoding a Public Land Mobile Network identifier (PLMN ID) of the PGW in a TEID/GRE Key field of a F-TEID information element. The method further includes the first CN transmitting the F-TEID information element containing the PLMN ID to the second CN. 
         [0009]    The SIRIG function supports both roaming and network sharing scenarios. (See SP-120252 and SP-120483). The solution to support the roaming scenario is specified in section 5.3.5.3 in 3GPP TS 23.060 as follows: “When the serving A/Gb mode SGSN receives SCI in a GTP-U packet, it copies it, without modifying its value, into a Gb interface information element that is sent by the SGSN in the downlink Gb interface user data packet to the GERAN access. In order to allow the GERAN to map the SCI into RRM behaviour, the downlink Gb interface user data packet also carries the HPLMN ID (in the IMSI parameter) and additional information, added by the SGSN, which indicates whether the SCI is assigned by a GGSN/P-GW in e.g. the Home PLMN or Visited PLMN. Absence of additional information is an indication of a VPLMN provided SCI 
         [0010]    The A/Gb mode GERAN uses the information from the SGSN to determine whether to map, and how to map, the SCI to the related RRM behaviour. If the GERAN is not configured with an SCI mapping for the SGSN provided information, then the GERAN shall treat the user plane packet normally, i.e. the GERAN ignores the SCI. 
         [0011]    NOTE 4: When sending downlink GTP-U packets, there are some transient periods where the “current RAT” information for the user may be incorrect at the GGSN/P-GW e.g. after a handover from (E)UTRAN to GERAN, or if the MS is in idle mode with ISR active, or if the MS is in idle mode and located in a Routing Area comprising GERAN and UTRAN cells. In these cases, the A/Gb mode GERAN may receive the first downlink user plane packets without Service Class Indicator.” 
         [0012]    Thus, the BS based on the knowledge of the international mobile subscriber identity (IMSI) and the additional information indicating whether the subscriber controlled input (SCI) is assigned by a GGSN/P-GW (e.g., the Home PLMN or Visited PLMN) interprets the semantics of SCI and apply relevant radio resource management (RRM) behaviors. But, the above solution may have a problem when SIRIG function is extended to LTE and UMTS because the enodeB (eNB) has no knowledge of IMSI. Therefore the solution doesn&#39;t work for LTE. 
         [0013]    When Direct Tunnel is used in 3G or 4G is used, the payload path may be RNC/eNB-SGW-PGW, which indicates that the SGW has to insert such “additional information indicating whether the SCI is assigned by a GGSN/P-GW in e.g. the Home PLMN or Visited PLMN.” When Direct Tunnel is not used, the payload path would be RNC-SGSN-SGW-PGW, which indicates that the SGSN has to insert such “additional information indicating whether the SCI is assigned by a GGSN/P-GW in e.g. the Home PLMN or Visited PLMN.”. 
         [0014]    Because both RNC and eNB support the Bearer Service concept (where the UMTS bearer service is specified in 3GPP TS 23.107 and EPS bearer is specified in the section 4.7 in TS 23.401), the SGW or MME/SGSN can inform RNC or eNB about PLMN of the PGW (i.e., the PLMN in which the PGW is located) for each bearer contexts within a given PDN connection. The SGW or MME/SGSN can inform RNC/eNB about the PLMN of the PGW during, for example, RAB assignment procedure and SRNS relocation procedure in 3G (or during initial UE context setup/E-RAB establishment and handover procedure in LTE). Both RNC and eNB have no PDN connection level concept but only hearer context within a PDN connection.

     DETAILED DESCRIPTION 
       [0018]    This disclosure relates to providing a PLMN identifier to a node of a radio access network (RAN). In embodiments, the present invention enables roaming support for SIRIG when it is used for UMTS and LTE. Thus, comparing with the existing solution, one or more embodiment are much more efficient as the PLMN information of the PGW is provided per bearer context, not per GTP-U packet, which reduces very much processing load in eNB  114 , RNC  106 , SGSN  108 , SGW  118 , as shown in  FIG. 1 . The disclosure also allows for transfer of information during handover procedures, useful for SIRIG solutions in UTRAN and E-UTRAN. 
         [0019]    I. Embed PLMN Identifier in the User Plane Address 
         [0020]    Before user plane data can be transferred to the UE  128  (see  FIG. 1 ), a user plane path, i.e., a bearer has to be established. The bearer establishment may happen during one or more of the following procedures: Initial attach (in E-UTRAN  112  in  FIG. 1 ), TAU with Active flag, PDP Context Activation, RAU with Follow-on-request flag, SRNS relocation (RAB need to be established in the target RAN before UE is moving in), etc. 
         [0021]    The SGW  118  (3G when DT is used or 4G for EPS), the SGSN  108  (when DT is not used in 3G), or the GGSN  110  (3G when DT is used but it is connected with Gn/Gp SGSN), will provide user plane transportation address (IP address+TEID=F-TEID) to the RAN via the MME  116 /SGSN  108  (through S1-MME and Iu interface). 
         [0022]    For 3G and when direct tunnel is used (or for 4G), the SGW will provide SGW F-TEID(s) for the user plane for each bearer context. The F-TEID(s) will be forwarded by the SGSN  108  or the MME  116  during RAB assignment procedure or during initial UE context setup/E-RAB establishment procedure to the RNC  106  or the eNB  114 . Those SGW F-TEID(s) are used by RNC  106  and eNB  114  to send any uplink user plane data. During SRNS relocation procedure in 3G or handover procedure in LTE, the target SGSN  108  or MME  116  provides the SGW  118  user plane F-TEID either received from the source MME  116 /SGSN  108  (in case the SGW is not relocated) or from a new SGW (in case the SGW is relocated). 
         [0023]    This disclosure proposes that the SGW  118  embed a PLMN identifier (PLMN ID) into the SGW F-TEID when it is sent to the MME  116 /SGSN  108 , where the embedded PLMN ID identifies the PLMN of the PGW  120  (i.e., the PLMN in which the PGW is located) associated with the UE  128 . This is illustrated in  FIG. 2 , which shows the SGW  118  receiving a create session request message from an MME  116  (or SGSN  108 ) and then transmitting a create session response message to the MME  116 /SGSN  108 , which creates a session response message that includes an F-TEID information element that contains a field containing the PLMN ID. 
         [0024]    F-TEID is an existing information element as specified in section 8.22 TS 29.274 and shown in FIGS. 8.22-1 of TS 29.274, which is reproduced below:

         [0025]    The Octets 6 to 9 (a.k.a., the TEID/GRE Key field) is encoded for TEID, where PLMN ID of the PGW  120  may be embedded according to an operator&#39;s configuration. That is, the PLMN ID of the PGW  120  may be encoded in the TEID/GRE Key field of the F-TEID information element. 
         [0026]    For 3G when direct tunnel is not used, the SGSN  108  will provide SGSN F-TEID to the RNC  106  during RAB assignment procedure (this is illustrated in  FIG. 3 ). Accordingly, the SGSN  108  can embed PLMN information of the PGW  120  for a given PDN connection into SGSN F-TEID, as described above. 
         [0027]    For legacy Gn/Gp SGSN interworking with a GGSN in another PLMN when direct tunnel is used, the GGSN may embed PLMN ID of the GGSN for a given PDP into GGSN TEID on the user plane, which will be forwarded by the Gn/Gp SGSN to the RNC  106  as described in  FIG. 4 . Stage 2 changes to current specifications may be needed in order to describe that the TEID forwarded to RNC  106  or eNB contains information about the HPLMN ID or VPLMN ID corresponding to the PGW  120  where the RAB is established. 
         [0028]    When indirect data forwarding is used during handover/SRNS relocation procedure and when the SGW  118  selected as data forwarding is NOT the anchor SGW, the forwarding SGW has no knowledge of PLMN information of the PGW  120 , thus those packets received via indirect tunneling may not associated with a PLMN information, hence they may not be correctly handled. This requires when setting up the indirect tunnel, the SGSN  108 /MME  116  shall either not use non-anchor SGW, or shall let the data forwarding SGW know about PLMN information of PGW  120 . This implies a protocol change—to add PLMN information of the PGW  120  in the GTP message “Create Indirect Data Forwarding Tunnel Request message”, so when data forwarding SGW  118  allocates SGW F-TEID for data forwarding, it can embed such PLMN information of the PGW into the SGW F-TEID. 
         [0029]    II. Provide PLMN ID During Bearer Establishment 
         [0030]    It is also possible to provide the PLMN ID of the PGW  120  serving the UE  128  to the RNC  106  or eNB  114  during RAB assignment procedure and SRNS relocation procedure (for 3G) or Initial UE context setup/E-RAB establishment procedure and handover procedure (for 4G), by the SGSN  108  or MME  116 . 
         [0031]    The procedure for RAB assignment procedure for 3G is described in the section 12.7.4.1 of TS 23.060 RAB Assignment Procedure Using Gn/Gp and in the section 8.2.2 of TS 25.413 and illustrated in  FIG. 5 . 
         [0032]    In the RAB Assignment Request message, a new IE, preferably called “PLMN of PGW/GGSN” is included, and associated with each RAB. Addition of the new PLMN of PGW/GGSN IE in the RAB Assignment Request message is shown in Table 1.  FIG. 6  illustrate a core network node (CN) transmitting a message of type RAB assignment request to an RNC  106 . The RAB assignment request message includes the PLMN ID of the PGW serving the UE that the RAB identified in the message is for. 
         [0033]    An MME may provide to an eNB  114  the PLMN ID using a message of type Initial Context Setup Request, as shown in  FIG. 7 . Addition of the new PLMN of PGW/GGSN IE in the INITIAL COTEXT SETUP message is shown in Table 2. 
         [0034]    An MME  116  may provide to an eNB  114  the PLMN ID using a message of type E-RAB Setup Request, as shown in  FIG. 8 . Addition of the new PLMN of PGW  120 /GGSN  110  IE in the E-RAB SETUP REQUEST message is shown in Table 3. Once the PLMN of PGW  120 /GGSN  110  has been transferred to the serving RAN according to the embodiment above, there is also the need to transfer such information during handover procedures across different base stations. This should be done both for UTRAN  102  and E-UTRAN  112  and both for network based handovers (i.e. S1 or RANAP handovers) or direct interface handovers such as X2 or Iur handovers. The S1 handover procedure for E-UTRAN  112  is described in TS23.401 section 5.5.1.2.2 and as is shown in  FIGS. 9A and 9B . In alternate embodiments, an equivalent procedure exists for UTRAN RANAP based handovers. 
         [0035]    In addition, when indirect tunneling is applicable, the target RAN should apply the received PLMN of the PGW  120  via Handover Request and Relocation Request also to that associated data forwarding tunnel. 
         [0036]    The new PLMN of PGW IE shall be added to the HNDOVER REQUEST message to communicate to the target RAN the PLMN ID of the PGW associated to the handed over RAB. An example of how such new IE could be included is shown in table 4. An equivalent modification can be applied to UTRAN  102  by adding the “PLMN of PGW/GGSN” IE by using a RANAP: RELOCATION REQUEST message. 
         [0037]    In case of mobility for E-UTRAN  112  and UTRAN  102  not involving the CN (i.e., X2 or Iur based mobility), the new information may be added to the respective mobility messages. For E-UTRAN  112  the X2 handover procedure is described in TS36.300 section 10.1.2.1.1. An equivalent procedure, SRNS relocation, exists for UTRAN over the Iur interface. 
         [0038]    For UTRAN  102 , the new PLMN of PGW IE shall be added to the HANDOVER REQUIRED message to communicate to the target RAN the PLMN ID of the PGW  120  associated with the handed over RAB. An example of how such new IE could be included is shown in the Table 5: Example of inclusion of new “PLMN of PGW” IE in the X2: HANDOVER REQUIRED message (see TS36.423). 
         [0039]    In the case of UTRAN  102 , the new PLMN of PGW/GGSN IE shall be added in the RNSAP: Enhanced Relocation Request message and in particular in the RANAP Enhanced Relocation Information Required IE defined in TS25.413. An example of how this could be achieved is shown in Table 6: Example of inclusion of new “PLMN of PGW/GGSN” IE in the RANAP Enhanced Relocation Information IE included in the RNSAP: Enhanced Relocation Request message (see TS25.423). 
         [0040]    The new information concerning the PLMN ID of the PGW  120 /GGSN  110  associated to the RAB handed over may be sent for each RAB. 
         [0041]    The information added to the messages and procedures above shall not be limited to the PLMN ID of the PGW  120 /GGSN  110  to which the RAB is associated. Such information could include any indication that allows the RAN to understand the actions to be taken upon reception of SIRIG-like marking. For example, the information added could consist of an index pointing at a particular SIRIG policy, which allows the RAN to understand the RRM policy so as to apply packets with specific SIRIG marking. 
         [0042]    III. Example Network Node 
         [0043]      FIG. 10  illustrates a block diagram of an example core network node. As shown in  FIG. 10 , the core network node includes: a data processing system (DPS)  402 , which may include one or more processors (P)  455  (e.g., microprocessors) and/or one or more circuits, such as an application specific integrated circuit (ASIC). Field-programmable gate arrays (FPGAs), etc.; a network interface  403  for connecting the network node to a network  130 ; a data storage system  406 , which may include one or more computer-readable data storage mediums, such as non-transitory memory unit (e.g., hard drive, flash memory, optical disk, etc.) and/or volatile storage apparatuses (e.g., dynamic random access memory (DRAM)). 
         [0044]    In embodiments where data processing system  402  includes a processor  455  (e.g., a microprocessor), a computer program product  433  may be provided, which computer program product includes: computer readable program code  443  (e.g., instructions), which implements a computer program, stored on a computer readable medium  442  of data storage system  406 , such as, but not limited, to magnetic media (e.g., a hard disk), optical media (e.g., a DVD), memory devices (e.g., random access memory), etc. In some embodiments, computer readable program code  443  is configured such that, when executed by data processing system  402 , code  443  causes the data processing system  402  to perform steps described herein. 
         [0045]    In some embodiments, network node is configured to perform steps described above without the need for code  443 . For example, data processing system  402  may consist merely of specialized hardware, such as one or more application-specific integrated circuits (ASICs). Hence, the features of the present invention described above may be implemented in hardware and/or software. For example, in some embodiments, the functional components of network node described above may be implemented by data processing system  402  executing program code  443 , by data processing system  402  operating independent of any computer program code  443 , or by any suitable combination of hardware and/or software. 
         [0046]    While various aspects and embodiments of the present disclosure have been described above, it should be understood that they have been presented by way of example only, and not limitation.
