Description
Identifying UE States by CN and UE
BACKGROUND OF THE INVENTION
1. Field of the Invention
This invention relates to a method for identifying states of UE receiving Multimedia Broadcast/Multicast Service (hereinafter referred to as MBMS) by CN (Core Network) and User Equipment (hereinafter referred to as UE) in a WCDMA system. It solves the problem that for a certain UE, if there is only existing Radio Resource Control (hereinafter referred to as RRC) and shared lu connection in the UE, existing state can't be described and can't be identified by SGSN and UE. It makes all the states of UE can be correctly identified at UE and SGSN.
2. Description of the Prior Art
At present, for MBMS services, there are two modes for shared signaling connection in signaling connection scheme on lu interface. One is that, for the UE receiving MBMS service, there is only a shared lu signaling connection. And the other is that a shared lu connection is established for the same services. If UE requires to receive other non-MBMS services or moves out cell, a dedicated lu signaling connection is then established for the UE.
Multicast Broadcast/Multicast Service (hereinafter referred to as MBMS) is a new service under standardization by 3rd Generation Partnership Project (hereinafter referred to as 3GPP). The standard under development is TR23.846, and the latest version is 1.0.0. MBMS service is a unidirectional point-to-multipoint (p-t-m) service, its most remarkable characteristic is that it can use radio resources and network resources efficiently.
Figure 1 describes the system structure of MBMS. The network structure of MBMS is based on the core network of General Packet Radio Service (hereinafter referred to as GPRS) and has added new network units. Hereinafter, the system structure of MBMS shown in Figure 1 will be described.
Broadcast/Multicast Service Center (referred to as BM-SC) 101 is the service control center of MBMS system. The transport network of MBMS service is composed of Gateway GPRS Supporting Node (hereinafter referred to as GGSN) 102 and Service GPRS Supporting Node (hereinafter referred to as SGSN) 103, and provide routes for data transfer. Home Location Register (hereinafter referred to as HLR) 106 saves the data related with users and can provide services such as user's authentication. UMTS Terrestrial Radio Access Network (hereinafter referred to as UTRAN) 104 provides radio resources for MBMS service over the air-interface. Iu 107 indicates the interface between Access Network and Core Network. User Equipment (hereinafter referred to as UE) 105 is a terminal device used to receive data. Radio resources used by MBMS service are not dedicated for one user, but are shared by all users using this service.
hi packet switching service field, the network has mobility management (hereinafter referred to as MM) function for tracing current location of Mobile Station (MS) in Public Land Mobile Network (hereinafter referred to as PLMN) and other
PLMN. hi Iu mode, the states of user MM include PMM-DETACHED, PMM-TDLE and PMM-CONNECTED. Each state describes a certain function and allocation information. The information saved in Mobile Station (hereinafter referred to as MS) and SGSN is called MM Context.
PMM-DETACHED: there is no communication between UE and SGSN, and SGSN and UE Contexts have no information on UE location or route. The SGSN do not know the location of UE.
PMM-IDLE: SGSN knows the accurate routing area of UE. SGSN and UE have established MM Context. To communicate with UE, it is necessary for SGSN to page for UE.
PMM-CONNECTED: SGSN knows the location of UE in SRNC. In this state, SRNC can trace the state of UE. Signaling connection of PS includes RRC connection and Iu connection established.
These three states can transit from one into another. The state transitions on UE side and on SGSN side are shown in Figure 2 and Figure 3 respectively.
The state transition on UE side is described in detail as following:
Transit from 201 PMM-DETACHED into 202 PMM-CONNECTED:
GPRS coimection: h order to complete GPRS connection, MM Context should transfer into PMM-CONNECTED state when PS signaling connection between MS and SGSN is established. If GPRS connection is accepted, MM Context is established in MS.
Transfer from 202 PMM-CONNECTED into 201 PMM-DETACHED:
GPRS detachment: when MS detaches with GPRS or GPRS detachment caused by the network is completed, PS signaling connection is released and MM Context transfers to PMM-DETACHED state. MM Context in MS can be deleted.
Route Area Update rejected: if Route Area Update is rejected, MM Context transfers to PMM-DETACHED state after PS signaling connection is released. MM .Context in MS can be deleted. -
GPRS connection rejected: if GPRS connection is rejected, MM Context transfers to PMM-DETACHED after PS signaling connection is released. MM Context in
MS can be deleted.
Transit from 202 PMM-CONNECTED into 203 PMM-IDLE :
PS signaling connection release: when PS signaling comiection is released, MM Context transfers to PMM-IDLE state.
Transit from 203 PMM-IDLE into 202 PMM-CONNECTED:
PS signaling connection establishment: when PS signaling connection is established between MS and SGSN, MM Context transfers to PMM-CONNECTED state.
Transit from 203 PMM-IDLE into 201 PMM-DETACHED:
Indirect GPRS detachment: e.g. when battery or Service Identity Module (hereinafter referred to as SIM) is taken down, MM Context transfers to PMM-DETACHED state in MS. The state transition on SGSN side is described in detail as following:
Transit from 301 PMM-DETACHED into 302 PMM-CONNECTED:
GPRS connection: in order to complete GPRS connection, when PS signaling comiection is established, MM Context transfers to PMM-CONNECTED state. If GPRS connection is accepted, MM Context is established in SGSN.
Transit from 302 PMM-CONNECTED into 301 PMM-DETACHED:
GPRS detachment: when MS has detached with GPRS or GPRS detachment caused by the network is completed, PS signaling connection is released and MM Context transfers to PMM-DETACHED state. MM Context in SGSN can be deleted.
Route Area Update rejected: if Route Area Update is rejected, MM Context transfers to PMM-DETACHED state after PS signaling connection is released.
GPRS connection rejected: if GPRS connection is rejected, MM Context transfers to PMM-DETACHED after PS signaling connection is released.
Transit from 302 PMM-CONNECTED into 303 PMM-IDLE: - PS signaling connection release: when PS signaling connection is released, MM
Context transfers to PMM-IDLE state.
Transit from 303 PMM-IDLE into 302 PMM-CONNECTED:
PS signaling connection establishment: when PS signaling connection is established between MS and SGSN, MM, Context transfers to PMM-CONNECTED state.
Transit from 303 PMM-IDLE into 301 PMM-DETACHED:
Indirect GPRS detachment: when MS timer is terminated, MM Context transfers to PMM-DETACHED state in SGSN. After a period of time (related with implementation), MM Context and PDP Context in SGSN can be deleted.
Transit from 302 PMM-CONNECTED into 302 PMM-CONNECTED:
- MS still returns back to PMM-CONNECTED state after executing SRNS relocation under PMM-CONNECTED state.
Existing SGSN and UE can only describe and identify following three states of user mobility management: PMM-DETACHED, PMM-IDLE and PMM-CONNECTED. MBMS service is a kind of new point-to-multipoint service, its feature is to use radio resources and network resources more efficiently by sharing. On Iu interface, signaling
coimection employs the means of shared or shared and dedicated UE connection established when required, in this connection means, UE may be in a new state: RRC connection and shared Iu connection for a certain MBMS service is established for UE, and there is no UE dedicated Iu connection; SRNC knows the location of UE and UE can receive data. The problem unsolved by existing specification is how SGSN and UE can identify this new state of UE.

The transition procedure of MM Context from PMM-IDLE to PMM-JOINT in MS and
SGSN
The transition procedure of MM Context from PMM-IDLE to PMM-JOINT in MS and SGSN is shown in Figure 6.
601 GGSN sends MBMS data to SGSN. 602 SGSN sends a "MBMS Notification" message including TMGI parameter to
RNC, and RNC notifies relevant UEs.
603 after MS receives the "MBMS Notification" message, if it wants to receive the MBMS service and according to' MM Context information, if it is in PMM-IDLE state, then it is decided to execute a RRC Connection Establishment procedure. 604 MS sends a "RRC Connection Request" message to RNC.
605 RNC sends a "RRC Connection Setup" message including signaling coimection information and transport channel information assigned to the UE to MS for notifying the acceptance of establishing RRC connection for the UE.
606 MS sends a "RRC Connection Setup Complete" message to confirm the establishment of RRC connection.
607 RNC analyzes the forthcoming MBMS service to check whether there is any Iu coimection used for this service. :
608 RNC sends a "MBMS Service Request" message to SGSN to request for the MBMS service. If there is no Iu connection used for this service, a shared Iu connection is established for this service while this message being sent.
609 SGSN updates MM Context into PMM-JOINT state.
610 and 611, if the UE requesting for service is the first one that requests for this service, SGSN establishes RAB for the MBMS service.
612 MS sends a "MBMS Service Request" message to RNC to request for establishing the corresponding RB.
613 RNC establishes RB for UE.
614 MS updates MS MM Context, which indicates that UE is in PMM-JOINT state.
615 When RAB establishment between RNC and SGSN is completed, SGSN starts to copy data and sends them to the RAB already established. RAN copies data and sends them through RB.
The transition procedure of MM Context from PMM-JOINT to PMM-IDLE in MS and
SGSN The transition procedure of MM Context from PMM-JOINT to PMM-IDLE in MS and SGSN is shown in Figure 7.
701 GGSN sends MBMS data."
702 When not receiving MBMS data any longer, SGSN regards that the shared Iu comiection for this MBMS service is not useful any longer and UE doesn't receive other MBMS service, and it is decided to release the shared Iu connection and RRC comiection.
703 SGSN sends an "Iu Release Command" to RNC to request for releasing the shared Iu connection as well as user plane resources.
704 RNC releases resources and sends an "Iu Release Complete" message to SGSN.
705 SGSN updates MM Context into PMM-IDLE state.
706 RNC sends an "RRC Connection Release" message to UE to request for releasing RRC comiection.
707 UE releases radio resources and signaling connection, and updates MM Context into PMM-IDLE state.
708 UE sends an "RRC Connection Release Complete" message to RNC.
The transition procedure of MM Context from PMM-JOJNT to PMM-DETACHED in
MS and SGSN The transition procedure of MM Context from PMM-JOJNT to PMM-DETACHED in MS and SGSN is shown in Figure 8.
801 UE is in PMM-JOTNT state and it is decided to perform GPRS detachment procedure.
802 UE sends a "Detach Request" message to SGSN. UE notifies SGSN whether the execution of GPRS detach is due to power off.
803 SGSN sends a "Delete PDP Context Request" message to GGSN.
804 GGSN makes the PDP Context of the UE invalid and returns a "Delete PDP Context Response" message to SGSN.
805 If UE notifies SGSN that the execution of GPRS detachment is not due to power off, SGSN sends a "Detach Response" message to UE.
806 SGSN releases the signaling comiection used for the UE, which includes the shared Iu (if the UE is the unique user that receives a certain MBMS service) and RRC comiection. ; '
807 SGSN updates MM Context into PMM-DETACHED state. 808 MS updates MM Context into PMM-DETACHED state.
The transition procedure of MM Context from PMM-JOINT to PMM-CONNECTED in MS and SGSN (this transition relation is only applicable to the case where a shared Iu coimection has existed and a dedicated Iu connection is established when necessary). The transition procedure of MM Context from PMM-JOINT to
PMM-CONNECTED in MS and SGSN is shown in Figure 9.
901 MS is in PMM-JOINT state and at this time there exist upstream data of non-MBMS service necessary to be transmitted. From MM Context, MS can get known that RRC connection has existed, so it is unnecessary to send an RRC Coimection Establishment message.
902 MS sends a "Service Request" message to SGSN for requesting SGSN to reserve resources. The service type, parameter of "Service Request" message shall be set as data. When RNC forwards UE's Non- Access Stratum message "Service Request" to SGSN, it initiates an Iu connection establishment procedure to establish a dedicated Iu coimection for this UE.
903 SGSN changes MM state into PMM-CONNECTED.
904 In the case where the service request is accepted, SGSN returns a "Service Acceptance" message to MS. .
905 SGSN sends an "RAB Allocation Request" message to RNC in order to request for establishing RAB.
906 RNC sends an "Establishment of RB" message to MS to notify MS new establishment of RAB ID request establishment of radio resources.
907 MS updates MM Context into PMM-CONNECTED.
908 MS and RNC return an "Establishment of RB Complete" message and an "RAB Allocation Response" message respectively, which indicate the completion of bearer establishment on user plane.
909 For each Re-established RAB by using modified QoS, SGSN initiates a "PDP Context Modification" procedure fo notify MS and GGSN of corresponding to the new negotiated QoS of PDP Context. 910 MS sends upstream data packets.
The transition procedure of MM Context from PMM-CONNECTED to PMM-JOINT in MS and SGSN (this transition relation is only applicable to the case where a shared Iu comiection has existed and a dedicated Iu coimection is established when necessary). The transition procedure of MM Context from PMM-CONNECTED to
PMM- JOINT in MS and SGSN is shown in Figure 10.
1001 User receives other non-MBMS service (e.g. voice) while receiving MBMS service.
1002 After voice service is' completed, SGSN regards that the dedicated Iu coimection is not useful any longer, so it is decided to release the dedicated Iu coimection as well as user plane resources.
1003 SGSN sends an "Iu Release Command" message to RNC.
1004 RNC releases signaling connection and user plane resources, and returns an "Iu Release Complete" message to, SGSN. 1005 SGSN updates MM Context into PMM-JOINT state.
1006 RNC sends a "RB Reconfiguration Request" to UE and releases radio resources used for non-MBMS service.
1007 UE releases radio resources and updates MM Context into PMM-JOINT state.
1008 UE sends a "RB Reconfiguration Complete" to RNC to notify RNC that radio bearer reconfiguration is completed.
