The detailed description of embodiment
GPRS (GPRS) is the standard of the grouped data in the relevant gsm system of ETSI (ETSI).GPRS is also accepted by Telecommunications Industries Association (TIA), as the packet data standard of TDMA/136 system.Functional by being public land mobile network (PLMN) interpolation GPRS, operator can allow its user with the resource effective and efficient manner, is linked into the network of outside internet protocol-based (IP).
Controlled by the ability and the carrier-in-interference of portable terminal, GPRS can provide the air interface transfer rate up to 115kbit/s.When introducing so-called EDGE technology (being the enhancing data rate of GSM and TDMA/136 evolution), even can also provide higher transfer rate.And GPRS allows several users to share identical air interface resource, and makes that operator can be according to the transmitting data stream amount, rather than the user is collected the expense of wireless service according to the connect hours.
The public land mobile network (PLMN) of supporting GPRS has been described, i.e. the configuration of cellular network among Fig. 1.Compare with traditional GSM network, GPRS introduces two new nodes that are used to handle Packet Service, i.e. Serving GPRS Support Node (SGSN) and Gateway GPRS Support Node (GGSN).These nodes all with attaching position register (HLR), mobile switching center (MSC/VLR) and base station system (BSS) interworking.
GGSN as the packet data network interconnection point is connected to SGSN through the IP backbone.User data (for example data from the GPRS terminal to the Internet) is packed, sends through IP is key.
Conversely, SGSN is connected to BSS again, and is in hierarchical level other places identical in the network with MSC/VLR.It follows the tracks of GPRS user's position, carries out safety function, and handles access control, and promptly to a great extent, it carries out MSC/VLR for Packet data service is the performed function of circuit-switched service.
Interconnection BSS and SGSN have been described among Fig. 2, have allowed the so-called Gb Interface of exchange signalling information and user data.
From Fig. 2 top, logic link control (LLC) protocol layer 201 provides reliable logical links between the travelling carriage of SGSN and work in SGSN provides the zone (being SGSN area) of service.LLC agreement 201 ends at travelling carriage and SGSN, and therefore it is transparent concerning BSS.
The major function of BSS GPRS agreement (BSSGP) layer 202 is provided at exactly and sends desired wireless relevant QoS of user data and routing iinformation between BSS and the SGSN.In BSS, it is as the interface between logic link layer control (LLC) protocol Data Unit (being the LLC frame) and Radio Link control/medium access control (RLC/MAC) piece.In SGSN, it can constitute the interface between RLC/MAC derivation information and the LLC frame.In GSM 08.18 standard, can find other details of BSSGP layer 202.
Network (NS) protocol layer 203 is realized the link layer of osi model.The NS layer is based on frame relay (FR), and provides Network for BSS GPRS agreement (BSSGP) layer.It allows to transmit BSSGP protocol Data Unit (PDU) in an orderly manner with non-reliable fashion, and promptly under unusual environment, PDU may lose, and can not keep the correct order of PDU.In GSM 08.16 standard, can find other details of Network layer 203.
Can utilize for example E1 or T1 transmission line, implement physical layer 204.
In the PLMN that supports GPRS, utilize IP network to interconnect between SGSN and the GGSN node, and SGSN is to utilize frame-relay network to be connected with the BSS node at present.Therefore Virtual network operator needs to make up, operates and safeguard IP network and frame-relay network.Preferably Virtual network operator only need be implemented IP network, and helps adding in Gb Interface the IP support like this.
Be when adding the IP support in the Gb Interface, in order to reduce influence to greatest extent to existing capability, and allow can to coexist based on IP with based on the Gb Interface of frame relay, therefore wish to revise the BSSGP protocol layer as few as possible, and preferably the BSSGP protocol layer is not made amendment.
In the BSSGP protocol layer, the notion of a key is exactly the virtual connection of so-called BSSGP (BVC) that communication path is provided between the BSSGP functional entity.Each BVC is used to transmitting BSSGP PDU between equity point-to-point (PTP) functional entity, between reciprocity point-to-multipoint (PTM) functional entity and between the reciprocity signaling capability entity.
The PTP functional entity is responsible for the PTP user data transmission.In each sub-district, there is a PTP functional entity.
The PTM functional entity is responsible for the PTM user data transmission.Only there is a PTM functional entity in each Network entity, and in each BSS, has one or more Network entities.
The signaling capability entity is responsible for for example other function of paging.Only there is a signaling entity in each Network entity, and in each BSS, has one or more Network entities.
Each BVC can be discerned by BSSGP virtual connection identifier (BVCI), and BVCI has the meaning end to end of crossing over Gb Interface.In the Network protocol layer, each BVCI also is unique in two peer-to-peer network Business Entities (NSE).Each Network entity can be identified by Network entity identifier (NSEI).NSEI identifies interior virtual a connection of BSSGP of SGSN jointly uniquely with BVCI.BVCI value 0 is illustrated in provides the BVC BSSGP of communication virtual connection between the reciprocity signaling capability entity, BVCI value 1 is illustrated in provides the BSSGP of communication virtual connection between the reciprocity PTM functional entity, BVCI then is illustrated in greater than 1 value the BSSGP of communication is provided between the reciprocity PTP functional entity virtual connection.
When adding the IP support, in order to minimize influence, need keep the notion of BVC to the BSSGP protocol layer, and because the unique identification of BVC requires the combination of BVCI and NSEI, so Gb Interface must continue to support the use of BVCI and NSEI.
Support IP has been described among Fig. 3, has kept the example embodiment of passing through the Gb Interface of revising of BVC notion simultaneously.
A New Deal layer, i.e. Network on the IP (NSOIP) 303 has replaced original NS protocol layer 202.NSOIP protocol layer 303 is suitable for BSSGP protocol layer 202 the identical business that is substantially similar to original NS protocol layer 203 is provided, but is to provide on the basis of business in the IP-based communication service of bottom, and no longer based on frame relay.Like this, NSOIP protocol layer 303 can be taken as NS protocol layer simulator.NSOIP protocol layer 303 is realized one group of corresponding PDU of each PDU that is realized with original NS protocol layer 203, but the PDU that NSOIP protocol layer 303 is realized comprises an additional NSEI information element.Compare with original NS protocol layer 203, another difference is NSOIP protocol layer 303 realization ordering mechanisms, to guarantee receiving the NSOIP PDU that exchanges with the order identical with transmission in two peer-entities.Perhaps, the NSOIP agreement can be moved on transmission control protocol (TCP), and owing to TCP guarantees to receive data according to the order identical with transmission, so the NSOIP agreement then no longer needs to realize ordering mechanism.
Be under the NSOIP protocol layer 303 protocol layer 304-306 all with generally acknowledge that known IETF structure is consistent.Datagram protocol (UDP) is used to transmission protocol layer 304, and the Internet (IP) agreement is used to internet layer 305, and physical layer 306 can be based on for example ATM or SDH/SONET.
A problem of existing Gb Interface based on frame relay is exactly: need to adopt management devices to carry out the configuration of the virtual connection of Network, promptly require artificial intervention.Particularly, the operation and maintenance personnel must manually determine when to be needed to distribute new NSEI value, and utilizes artificial process, also must guarantee the uniqueness of new NSEI value in SGSN.This is a very loaded down with trivial details process, if the particularly different operation and maintenances of organizing responsible respectively SGSN and base station system is then all the more so.
The present invention addresses the problem: provides and disposes Gb Interface more flexibly, and the method for particularly utilizing the Gb Interface of communicating by letter based on IP.
