Wireless communication system and method for implementing evolution system accessory program

The present invention is generally associated with an evolutionary wireless communication system (e.g., Evolutionary Global System for Mobile Communications (UMTS) Terrestrial Radio Access Network (E-UTRAN)). More particularly, the present invention relates to a wireless communication system and method for implementing an evolved system accessory program.

The evolution of the third generation (3G) system provides higher data transfer rates, lower latency, and support for multiple radio access technologies (RATs). The main features of this evolutionary third-generation (3G) system include an enhanced null intermediation for more efficient higher data rate processing and optimization of traditional processing procedures to reduce the number of times the signalling program is sent and Reduce set delays and optimize network design at the same time to allow for any kind of global mobile communication system (GSM), integrated packet radio service (GPRS), broadband division multiple access system (WCDMA), multiple division of labor Interconnection and interoperation within any empty interfacing planes of System 2000 (CDMA2000), IEEE 802.xx, and the like.

Figure 1 shows the traditional Integrated Packet Radio Service (GPRS) access interface and reference point. A mobile station (MS) 102 includes a terminal equipment (TE) 104 and a mobile terminal (MT) 106 attached to a plurality of integrated packet radio service (GPRS) packet domain networks 108a, 108b, and Further connected to a package data network 110. The Integrated Packet Radio Service (GPRS) packet domain network 108a, 108b implements network access control functions, packet routing and delivery functions, mobility management functions, logical link management functions, radio resource management functions, network management functions, or Other similar features.

The network access control functions include login, authentication and authorization, admission control, message filtering, packet format modification, charging data collection, operator-determined prohibition or the like. The packet routing and delivery functions include relaying, routing, address compilation and mapping, encapsulation, tunneling, compression, encryption, domain name servers, or the like. The logical link management function includes a meeting of establishing, maintaining, and releasing.

Figures 2A and 2B show a conventional state machine for action management (MM) for a mobile station (MS) and a service integrated packet radio service (GPRS) support node (SGSN) in Iu mode. The mobile station (MS) and the service integration packet radio service support node (SGSN) may be one of a packet action management (PMM) separation state, a packet action management (PMM) connection state, and a packet action management (PMM) idle state. In the Packet Action Management (PMM) split state, there is no communication between the mobile station (MS) and the Service Integration Packet Radio Service Support Node (SGSN). In order to establish a Mobile Management (MM) context in the Mobile Station (MS) and the Service Integration Packet Radio Service Support Node (SGSN), the Mobile Station (MS) performs an Integrated Packet Radio Service (GPRS) attachment procedure. Once the Integrated Packet Radio Service (GPRS) is attached, its status changes to the Packet Action Management (PMM) connection state and a packet is established between the Mobile Station (MS) and the Service Integration Packet Radio Service Support Node (SGSN). Switch (PS) to send a connection. The Packet Switching (PS) signaling connection also releases and changes its state to the Packet Action Management (PMM) idle state. Integrated Packet Radio Service (GPRS) separation, Packet Switching (PS) Attachment Rejection, or Routing Area Update (RAU) rejection will cause its state to change to a Packet Action Management (PMM) separation state. In the Packet Action Management (PMM) idle state and the Packet Action Management (PMM) connection state, the talk management (SM) state may be a start or fail state.

3A, 3B, and 3C are combined to be an attachment program 300 transmission map in a conventional integrated packet radio service (GPRS) system. As shown in FIG. 3A, a mobile station (MS) 302 transmits an attachment request message to a new service integration packet radio service support node (SGSN) 306 for initialization of the accessory program 300 (step 322). The attachment request message contains an International Mobile Subscriber Identity (IMSI) (or may be replaced by a Packet Temporary Mobile Subscriber Identity (P-TMSI) and an Old Route Range Identifier (RAI)), an attachment form or other analog.

If the mobile station (MS) 302 identifies itself as a Packet Temporary Mobile Subscriber Identity (P-TMSI), the new Service Integrated Packet Radio Service Support Node (SGSN) 306 derives from the Route Range Identifier (RAI). The old service integrates the Packet Radio Service Support Node (SGSN) address to request the International Mobile Subscriber Identity (IMSI) of the mobile station (MS) 302 (step 324). The new Service Integration Packet Radio Service Support Node (SGSN) 306 transmits an identification request message to the old Service Integration Packet Radio Service Support Node (SGSN) 308 (step 326). The identification request message includes a packet temporary mobile subscriber identity (P-TMSI), an old routing range identifier (RAI), an old packet temporary mobile subscriber identity (P-TMSI) signature or the like. . The old Service Integration Packet Radio Service Support Node (SGSN) 308 checks the packet Temporary Mobile Subscriber Identity (P-TMSI) for the record and transmits the Mobile Station (MS) 302 International Mobile Subscriber Identity (IMSI). The identification response message to the new service integration packet radio service support node (SGSN) 306 (steps 328 and 330). If the old service integration packet radio service support node (SGSN) 308 or the old packet temporary mobile subscriber identity (P-TMSI) is not aware of the mobile station (MS) 302, the old service The Integrated Packet Radio Service Support Node (SGSN) 308 responds with an identification response message containing the International Mobile Subscriber Identity (IMSI), Authorization Triad, or Authorized Five-Byte. If the old service integration packet radio service support node (SGSN) 308 is not aware of the mobile station (MS) 302, or the old packet temporary mobile subscriber identity (P-TMSI) does not match the store in the The old service integrates the value in the Packet Radio Service Support Node (SGSN) 308, and the old Service Integration Packet Radio Service Support Node (SGSN) 308, at step 330, causes an appropriate error in the identification response message to proceed. Respond.

If the mobile station (MS) 302 is not known among the old service integration packet radio service support node (SGSN) 308, the new service integration packet radio service support node (SGSN) 306 transmits an identification code (ID). The request (identification code (ID) form is an International Mobile Subscriber Identity (IMSI)) to the mobile station (MS) 302 (step 334). The mobile station (MS) 302 responds with an identification code (ID) response containing the International Mobile Subscriber Identity (IMSI) of the mobile station (MS) 302 (step 336).

If there is no Action Management (MM) context for the mobile station (MS) anywhere in the network, the mobile station (MS) 302, the new service integration packet radio service support node (SGSN) 306 and a zone location recorder (HLR) 314 perform an authentication procedure (step 338).

(SGSN) 306 and an Equipment Identification Recorder (EIR) 310 perform an International Mobile Equipment Identity (IMEI) check procedure (step 340). If the number of the Service Integrated Packet Radio Service Support Node (SGSN) changes due to the previous Integrated Packet Radio Service (GPRS) separation, or if it happens to be the first attachment, the new Service Integration Packet Radio Service Support Node (SGSN) 306 The local location recorder (HLR) 314 is updated by transmitting an update location message to the local location recorder (HLR) 314 (step 342). The update location message includes a Service Integration Packet Radio Service Support Node (SGSN) number, a Service Integration Packet Radio Service Support Node (SGSN) address, the International Mobile Subscriber Identity (IMSI) or the like.

The local location recorder (HLR) 314 compares the number of service integration packet radio service support nodes (SGSNs) with a record value and transmits a cancel location message (including an International Mobile Subscriber Identity (IMSI), in the form of cancellation) to the The old service integration packet radio service support node (SGSN) 308 (step 344, step 346). The old service integration packet radio service support node (SGSN) 308 performs a confirmation operation with a cancel location confirmation (step 348). The local location recorder (HLR) 314 transmits an Insert User Profile message to the new Service Integration Packet Radio Service Support Node (SGSN) 306, which includes an International Mobile Subscriber Identity (IMSI) and Integrated Packet Radio Service (GPRS). Subscription Information (Step 350)

The new Service Integration Packet Radio Service Support Node (SGSN) 306 checks if the mobile station (MS) 302 is not allowed to exist in the new routing range (RA) (step 352). If the mobile station (MS) 302 does not allow to be attached to the routing range (RA) due to regional subscription restrictions or access restrictions, the new service integration packet radio service support node (SGSN) 306 facilitates one. Reject the attachment request for an appropriate reason, and may reply to an Insert User Profile Confirmation (including the International Mobile Subscriber Identity (IMSI), a Service Integration Packet Radio Service Support Node (SGSN) Range Restriction Message) to the local location recorder ( HLR) 314 (step 354). If the subscription check fails for other reasons, the new Service Integration Packet Radio Service Support Node (SGSN) 306 also rejects the attachment request with an appropriate reason and replies with an Insert User Profile Confirmation (including the International Mobile Subscriber Identity (IMSI) And the reason) to the local location recorder (HLR) 314. If all checks are successful, the new Service Integration Packet Radio Service Support Node (SGSN) 306 constructs an Action Management (MM) context for the Mobile Station (MS) 302 and replies with an Insert User Profile Confirmation (including The International Mobile Subscriber Identity (IMSI) is sent to the local location recorder (HLR) 314 (step 356, step 358). The local location recorder (HLR) 314 updates the mobile management (MM) context and transmits an update location confirmation to the new service integration packet radio service support node (SGSN) 306 (step 360, step 362).

Referring to Figure 3C, if a form of attachment specified in the attachment request indicates a combined Integrated Packet Radio Service (GPRS)/International Mobile Subscriber Identity (IMSI) attachment, a Visitor Location Recorder (VLR) should be updated. 312. The new Service Integration Packet Radio Service Support Node (SGSN) 306 transmits a location update request to a new Visitor Location Recorder (VLR) 312 (step 364). The location update request includes a new Location Range Identifier (LAI), the International Mobile Subscriber Identity (IMSI), the Number of Service Consolidated Packet Radio Service Support Nodes (SGSNs), a location update format, or the like.

The new Visitor Location Recorder (VLR) 312 establishes a connection with the new Service Integration Packet Radio Service Support Node (SGSN) 306 by storing the number of Service Integration Packet Radio Service Support Nodes (SGSNs). If the location range (LA) update occurs between the Mobile Switching Centers (MSCs), the new Visitor Location Recorder (VLR) 312 transmits an Update Location Message (containing the International Mobile Subscriber Identity (IMSI) and the new The Visitor Location Recorder (VLR) is directed to the local location recorder (HLR) 314 (step 366). The local location recorder (HLR) 314 transmits a cancel location message to the old visitor location recorder (VLR) 316 (step 368). The old Visitor Location Recorder (VLR) 316 confirms with a Cancel Location Confirmation (step 370).

The local location recorder (HLR) 314 transmits an inserted subscriber profile message (containing the International Mobile Subscriber Identity (IMSI) and subscriber profile) to the new Visitor Location Recorder (VLR) 312 (step 372). The new Visitor Location Recorder (VLR) 312 confirms with an Insert User Profile Confirmation (step 374). After completing the mobile switching center (MSC) location update procedure, the local location recorder (HLR) 314 utilizes an update location confirmation to respond to the new visitor location recorder (VLR) 312 (step 376). The new Visitor Location Recorder (VLR) 312 utilizes a Location Update Accept message (including the Visitor Location Recorder (VLR) Temporary Mobile Subscriber Identity (TMSI)) to respond to the new Service Integration Packet Radio Service Support Node. (SGSN) 306 (step 378).

The attachment acceptance message includes a packet Temporary Action User Identification Number (P-TMSI), Visitor Location Recorder (VLR) Temporary Mobile Subscriber Identity (TMSI), and Packet Temporary Mobile Subscriber Identity (P-TMSI) signature. Chapter and Radio Priority Short Message Service (SMS). The mobile station (MS) 302 then replies an attachment completion message to the new service integration packet radio service support node (SGSN) 306, and the new service integration packet radio service support node (SGSN) 306 transmits a temporary mobile user The identification code (TMSI) redistributes the completion message to the new visitor location recorder (VLR) 312 (steps 382, 384).

Figure 4 is a diagram of a conventional state machine for meeting management (SM). A Integrated Packet Radio Service (GPRS) subscription subscribes to one or more Packet Data Protocol (PDP) addresses. Each Packet Data Agreement (PDP) address is a member of the contents of a Package Data Agreement (PDP). The Packet Data Agreement (PDP) status indicates whether data transfer to the Packet Data Protocol (PDP) address can be made. When the packet data protocol (PDP) context is initiated, the packet data contract (PDP) state changes from a failed state to a boot state. The startup state is changed to a failure state after the failure procedure is initialized, or when the action management (MM) state is changed to the packet action management (PMM) idle state or the packet action management (PMM) separation state.

In the failed state, the data service for the mobile station (MS) specific packet data protocol (PDP) address is not activated, and the packet data protocol (PDP) text does not contain data for processing and packet data.

The Talk Management (SM) and Mobile Management (MM) in accordance with the present invention employs Internet Protocol (IP) address allocation for full operation of the WTRU. If the WTRU is in a connected state, the Internet Protocol (IP) address is assigned. If no Internet Protocol (IP) address is assigned, the WTRU is in a separate state (in other words, unavailable or offline). In accordance with the present invention, the WTRU state (availability) is related to the Internet Protocol (IP) address assignment. The state transitions between the action management (MM) states also change accordingly.

Switch (PS) the release of the signaling connection. When the action and management (SMM) state is changed to the action management (MM) connection and the meeting management (SM) activation state in the action management (MM) idle and talk management (SM) start state, the establishment is started. Packet Switching (PS) sends a connection. Evolutionary system separation, packet switching (PS) attachment rejection, or radio access technology (RAT) handover rejection will result in the change of the talk and action management (SMM) state to action management (MM) separation and conference management (SM) failure status. .

9A through 9C are flow diagrams of an evolution system attachment and recording program 1000 in accordance with the present invention. A wireless transmit/receive unit (WTRU) 1002 initiates initialization of the nearby program 1000 by transmitting an attachment request message to a new core network (CN) 1006 (in other words, an evolved core network (CN)) (step 1022). . The attachment request message contains an International Mobile Subscriber Identity (IMSI) (either a Temporary Mobile Subscriber Identity (P-TMSI) and an old Routing Range Identifier (RAI), an attachment form, or other similar information. If the WTRU 1002 identifies itself to have the Packet Temporary Mobile Subscriber Identity (P-TMSI), the new Core Network (CN) 1006 derives from the Routing Range Identifier (RAI). An old service integration packet radio service support node (SGSN) address requests the International Mobile Subscriber Identity (IMSI) information of the WTRU 1002 (step 1024). The new core network (CN) 1006 transmits an identification request message to the old service integration packet radio service support node (SGSN) 1008 (step 1026). The identification request message includes a packet temporary mobile subscriber identity (P-TMSI), an old routing range identifier (RAI), an old packet temporary mobile subscriber identity (P-TMSI) signature, or the like.

Respond with an appropriate error. If the WTRU 1002 is not aware of the old Service Consolidation Packet Radio Service Support Node (SGSN) 1008, the new Core Network (CN) 1006 transmits an identification request (identification form) = International Mobile Subscriber Identity (IMSI) to the WTRU 1002 (step 1032, step 1034). The WTRU 1002 then responds with an appropriate identification response including the International Mobile Subscriber Identity (IMSI) of the WTRU 1002 (step 1036).

If there is no Mobile Management (MM) context for the WTRU 1002 in the network, the WTRU 1002, the new core network (CN) 1006 performs an authentication step with the local location recorder (HLR) 1014 (step 1038). Depending on the operator configuration, an International Mobile Equipment Identity (ID) can be selectively implemented by the WTRU 1002, the new Core Network (CN) 1006, and an Equipment Identification Recorder (EIR) 1010 ( IMEI) checks the program (step 1040).

The new core network (CN) 1006 checks if the WTRU 1002 is allowed to be present in the new routing range (RA) (step 1052). If the WTRU 1002 does not allow attachments in the routing range (RA) due to usage restrictions or access restrictions in the area, the new core network (CN) 1006 is The attachment request is rejected for an appropriate reason, and an insert user profile confirmation (including the International Mobile Subscriber Identity (IMSI), Core Network (CN) Range Restriction message) is sent to the local location recorder (HLR) 1014 (step 1054). If the usage check fails for other reasons, the new core network (CN) 1006 also rejects the attachment request with an appropriate reason and replies with an insert user profile confirmation (including the International Mobile Subscriber Identity (IMSI) and reason) ) to the local location recorder (HLR) 1014. If all checks are successful, the new core network (CN) 1006 constructs a talk and action management (SMM) context for the WTRU 1002 to initiate the packet data protocol (PDP). The text (step 1056), and replies with an insert user profile confirmation (including the International Mobile Subscriber Identity (IMSI), a Packet Data Protocol (PDP) format, a Packet Data Protocol (PDP) address, an access point name (APN), a tunneling endpoint identification code (TEID) or other similar information) to the local location recorder (HLR) 1014 (step 1058). The local location recorder (HLR) 1014 updates the talk and action management (SMM) context and transmits an update location confirmation to the new core network (CN) 1006 (step 1060, step 1062).

A visitor location record should be updated if the form of attachment specified in the attachment request indicates a combined evolved Global System for Mobile Communications terrestrial Radio Access Network (E-UTRAN)/International Mobile Subscriber Identity (IMSI) attachment.

When the core network (CN) wishes to transmit protocol data (eg, configuration parameters, error codes, or messages/events) to the WTRU, the protocol acceptance message includes the protocol configuration. Option information member. If the core network (CN) wants to indicate the packet flow identifier associated with the packet data protocol (PDP) context, the attachment flow identifier includes the packet flow identifier information member. If the WTRU does not indicate PFC program support in the PFC Feature Mode field of the WTRU network capability information member, the core network (CN) should not contain Member of this information. If the WTRU does not indicate PFC program support, it should ignore this information member when it receives.

The Negotiation Logical Link Control (LLC) Service Access Point Identifier (SAPI), Negotiation Quality of Service (QoS), Wireless Priority and Alternate Half Octets are used to map the service to the network with the correct settings. The information member of the correct endpoint. The Negotiation Logical Link Control (LLC) Service Access Point Identifier (SAPI) indicates the WTRU, the Evolutionary Global System for Mobile Communications, Terrestrial Radio Access Network (E-UTRAN), and the evolutionary core Service access point identification among the two networks (CN). This ensures that traffic for a particular service can be routed through the same node in both the uplink and downlink links. Negotiation Quality of Service (QoS) is a set of characteristics for the traffic flow that specifies the resources being allocated, such as bit-law, speech quality, bit error rate, protocol data unit (PDU) size, or other similar information. The wireless priority information member is used to set the data traffic category for the wireless access network (RAN).
