Wireless communication system and method for implementing evolution system connection 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 evolution system connection procedure.

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 device (TE) 104 and an action A terminal (MT) 106, which is coupled to a plurality of integrated packet radio service (GPRS) packet domain networks 108a, 108b, and further coupled to a packet 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 dialogue 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) connection procedure. Once the Integrated Packet Radio Service (GPRS) link is made, its status changes to the Packet Action Management (PMM) connection status 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) Link 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 session management (SM) state may be a start or fail state.

3A, 3B, and 3C are combined to be a link diagram of a connection procedure 300 in a conventional integrated packet radio service (GPRS) system. As shown in FIG. 3A, a mobile station (MS) 302 performs a connection procedure 300 (step 322) initialization by transmitting a link request message to a new service integration packet radio service support node (SGSN) 306. The link request message contains an International Mobile Subscriber Identity (IMSI) (or can be replaced with a Packet Temporary Action User ID (P-TMSI) and an old Route Range Identifier (RAI)), a link type 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 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. Response.

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) type 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).

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 connection in 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 The connection request is rejected for an appropriate reason, and an incoming user profile confirmation (including the International Mobile Subscriber Identity (IMSI), a Service Integration Packet Radio Service Support Node (SGSN) range restriction message) may be replied to the local location recorder ( HLR) 314 (step 354). If the subscription check fails for other reasons, the new Service Integrated Packet Radio Service Support Node (SGSN) 306 also rejects the link 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, a Visitor Location Recorder (VLR) should be updated if the type of link specified in the link request indicates a combined Integrated Packet Radio Service (GPRS)/International Mobile Subscriber Identity (IMSI) link. 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 Integration Packet Radio Service Support Nodes (SGSNs), location update type, 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 wireless communication system includes a first core network (in other words, a traditional third generation partnership project (3GPP) core network) and a second core network (in other words, an evolved core network), the second core network The road evolved from the first core network. The evolved WTRU operation in the evolved system transmits a modified link request message to the evolved core network upon initiation. Once received, the evolved core network implements the same procedures (eg, authentication, authorization, action management, or other similar functionality) as indicated in the 3rd Generation Partnership Project (3GPP) TS23.060 PS Linker. The evolved core network then initiates the Packet Data Protocol (PDP) context action (for the allocation and configuration of the Predetermined Internet Protocol (IP) address of the WTRU). Once the Internet Protocol (IP) configuration process (PPP) context is successfully completed, the evolved core network transmits the new link accept message to the WTRU. . The new link acceptance message contains information about the contents of the Packet Data Agreement (PDP) (eg, Internet Protocol) Protocol (IP) address, Internet Protocol (IP) version (in other words, version 4 or version 6), access point name (APN) information, quality of service (QoS), or other similar information. The evolved core network also constructs a Session and Action Management (SMM) context for dialog management (SM) and action management (MM) for the WTRU. According to the present invention, the session management (SM) and action management (MM) state can be based on a traditional third generation partnership project (3GPP) based action management (MM) and session management (SM) state (at the first In the core network) it varies. The Session Management (SM) and Action Management (MM) according to the present invention employs Internet Protocol (IP) address allocation for the 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.

9A through 9C are flow diagrams of an evolution system linking and recording program 1000 in accordance with the present invention. A WTRU 1002 performs initialization of the nearby program 1000 by transmitting a link request message to a new core network (CN) 1006 (in other words, the evolved core network (CN)) (step 1022). . The link request message contains an International Mobile Subscriber Identity (IMSI) (either a Temporary Mobile Subscriber Identity (P-TMSI) and an old Route Range Identifier (RAI), a link type, 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.
