Description
Technical field
The present invention relates to the mobile communications network access technology, refer to a kind ofly in evolvement network (EvolvedNetwork) especially, be connected the method for setting up between travelling carriage and evolution block core net.
Background technology
Universal mobile telecommunications system (UMTS) is a kind of third generation cordless communication network technical standard of third generation partner program (3GPP) tissue definition, and this standard has been issued REL-99, REL-4, REL-5 and REL-6 version.The UMTS network is made up of core net (Core Network) and UTMS land radio access web (UTRAN, UMTS Terrestrial Radio Access Network).Core net comprises circuit domain (CS, Circuit Switch) and two parts of packet domain (PS, Packet Switch), wherein, circuit domain provides based on Circuit-switched business such as speech business, and packet domain provides business such as internet (Internet) visit based on packet switching.The terminal that the user uses in the UMTS network is subscriber equipment (UE, User Equipment).
Fig. 1 is the schematic network structure of prior art UMTS, as shown in Figure 1, because this paper only relates to the packet domain part, therefore the circuit domain part is not shown in Figure 1 in the core net, and core net is made up of Serving GPRS Support Node (SGSN), Gateway GPRS Support Node (GGSN) and attaching position register (HLR); Access Network is made up of radio network controller (RNC) and base station node B.UE is mutual by carrying out between Uu interface and NodeB, and each RNC can connect some NodeB, and each SGSN can connect some RNC.Be to be to be between Iu interface, SGSN and the GGSN between Gn/Gp interface, SGSN and the HLR between Iub interface, RNC and the SGSN between NodeB and the RNC for being Gc interface, GGSN and outside packet data network (PDN between Gr interface, GGSN and the HLR, Packet Data Network) be the Gi interface between, PDN is meant the general name of all packet data network herein, and it can be Internet network or enterprise network or the like.
Wherein, the Uu interface is the air interface of UMTS network.Physical layer (PHY or L1) agreement is positioned at NodeB, belongs to the ground floor agreement of Uu interface; Medium access control (MAC) agreement, Radio Link control (RLC) agreement, packet data convergence protocol (PDCP) and broadcast/multi broadcast control protocol (BMC, Broadcast/Multicast Control) are positioned at RNC, belong to the second layer agreement of Uu interface; RRM (RRC) agreement is positioned at RNC, belongs to the 3rd layer protocol of Uu interface.The PHY agreement mainly finish physical channel processing, transmit and receive physical channel; The main completion logic channel of MAC agreement is to the mapping and the scheduling feature of transmission channel; Rlc protocol is mainly finished the segmentation/reorganization of data and is retransmitted; PDCP mainly finishes the sequence number of IP the compression/de-compression and the service data of data; The BMC agreement is mainly finished the buffer memory and the scheduling of cell broadcast messages; And the RRC agreement is the core of Uu interface, and the RRC agreement is responsible for the management of Radio Resource, finishes configuration and control to lower-layer protocols PHY/MAC/RLC/PDCP/BMC.
The Iu interface is the key interface of Access Network and core net, and the management of Radio Resource and control are isolated in the Access Network by the Iu interface, makes core net that professional providing only is provided.The Iu interface comprises chain of command agreement and user plane protocol, and the chain of command agreement is mainly finished the mutual of signaling message and handled, and user plane protocol is mainly finished the transmission of user data.The Iu interface of R99 and R4 version adopts the ATM transmission technology, and from the R5 version, the Iu interface both can adopt asynchronous transfer mode (ATM, Asynchronous Transfer Mode) transmission technology also can adopt the IP transmission technology.When adopting the IP transmission technology, can adopt IP bearer network such as Ethernet that the transmission of signaling and business datum is provided between RNC, the SGSN.
Fig. 2 is among the UMTS, the protocol stack schematic diagram of the Iu interface of the employing IP transmission technology of 3GPP definition, as shown in Figure 2, the Iu interface is divided into two-layer in the horizontal: wireless network layer and transport network layer, wherein, wireless network layer is responsible for handling and the wireless technology function associated, and transport network layer is responsible for handling and the transmission technology function associated; The Iu interface is divided into two faces in the vertical: chain of command and user's face.Wherein, chain of command is responsible for the management of mutual, the user plane bearer link of signaling message, the user plane bearer link is meant and is positioned at bearing link user's face, that be used to transmit the user grouping data, such as GPRS tunnel User Agreement (GTP-U, GPRS Tunneling Protocol-User) tunnel; User's face is responsible for the encapsulation and the transmission of user data.
As shown in Figure 2, the wireless network layer of chain of command is Radio Access Network Application Part (RANAP, a Radio Access Network Application Part) agreement, and signaling messages of wireless network layer is mutual between responsible SGSN and RNC; And the wireless network layer of user's face is Iu user plane (Iu UP, an Iu UserPlane) agreement, is responsible for the frame of user data and handles.In packet domain, Iu UP adopts transparent mode, and promptly Iu UP does not do any processing to user data, and user data is transparent transmission in Iu UP, therefore, can think that also user's face of packet domain Iu interface does not have processing protocol at wireless network layer.
The transport network layer of chain of command comprises that these agreements of SCCP/M3UA/SCTP/IP/L1 finish the route and the reliable transmission of RANAP message jointly.Wherein, SCCP (SCCP) agreement can provide to connect and not be connected two kinds of services with having to RANAP, and usually, the Connection Service that has that the RANAP message relevant with calling uses SCCP to provide transmits; And transmit with the no Connection Service that irrelevant RANAP message uses SCCP to provide is provided, use connectionless SCCP to transmit such as beep-page message.MTP3-user adaptation layer (M3UA)/stream control transmission protocol (sctp) is finished the adaptive and route to SCCP message, guarantees the SCCP message complete, is sent to the destination correctly, reliably.
The transport network layer of user's face comprises the GTP-U/UPD/IP/L1 agreement, and these agreements are finished the transmission of user grouping data jointly.Wherein, the GTP-U agreement is used for transmitting for user's business datum provides the tunnel at transmission network, and the GTP-U data are by User Datagram Protoco (UDP) (UDP)/Internet agreement (IP) agreement carrying of lower floor.
Usually, the 3GPP network is divided into Access Network and core net is two-layer, Access Network is Access Layer (AS, Access Stratum), core net is Non-Access Stratum (NAS, NonAccess Stratum), UE and Access Network interactive signaling message are referred to as AS message, and UE and core net interactive signaling message are referred to as NAS message.NAS message comprises the signaling message relevant with mobile management, the signaling message of being correlated with session management, and the signaling message relevant with short message service.UE adheres in start, when Routing Area Update, service request or page response, need carry out Signalling exchange with the SGSN in the core net, and these signaling messages belong to NAS message.NAS message aloft in the interface as Non-Access Stratum protocol Data Unit (NAS-PDU) data, be carried in the AS message and transmit.
Carry out before the Signalling exchange between UE and SGSN, UE need set up signaling with SGSN and be connected, signaling connection herein can abbreviate connection as, thereby in each node of communication such as RNC, SGSN, set up communication context for UE, be the resource of allocation of communications necessity simultaneously, make UE to carry out the mutual of signaling message with SGSN.Setting up signaling connects and to comprise: UE is connected foundation and RNC and is connected two processes of setting up with Iu between the SGSN with RRC between the RNC.
Fig. 3 be prior art UE with SGSN between signaling be connected the flow chart of setting up, when UE carried out network attachment, Routing Area Update, packet service call or page response etc., it was the NAS interacting message alternately that UE need carry out signaling message with SGSN.Before sending NAS message, UE can check self whether set up with RNC between RRC is connected, if following steps are then carried out in not foundation:
Step 300～step 301:UE sends RRC connection request (RRC ConnectionRequest) message to RNC, and request is set up RRC with RNC and is connected; After RNC received RRC connection request message, for UE sets up communication context, distributes and set up wireless channel, afterwards, RNC returned RRC to UE and connects foundation (RRC Connection Setup) message.
Step 302:UE receive RRC connect set up message after, set up the parameter of carrying in the message according to this RRC connection, create and each layer protocol of configuration Uu interface, set up and activate up channel, afterwards, UE returns RRC connection foundation to RNC and finishes (RRC Connection Setup Complete) message, sets up to show the RRC successful connection.
Above-mentioned steps 300～step 302 connects the process of setting up for RRC.
After step 303:RRC successful connection was set up, UE sent to RNC as the NAS-PDU data carry initial directly the transmission in (Initial Direct Transfer) message with NAS message.
Should initially directly transmit the destination information that can carry the NAS-PDU data in the message,, suppose here that the NAS-PDU data were sent to the SGSN in the packet-based core networks such as being packet-based core networks or circuit core net.
Step 304:RNC receives after carry the NAS-PDU data initial directly transmit message, RNC can check self whether set up with SGSN between Iu is connected, if do not set up, then RNC is that Iu connects Iu connection identifier of distribution; RNC reads the initial NAS-PDU data that directly transmit in the message, and is encapsulated in initial UE message again in (Initial UE Message), carries described Iu connection identifier simultaneously in initial UE message, and RNC sends initial UE message to SGSN; After SGSN received initial UE message, for UE sets up communication context, storage Iu connection identifier and UE sign were distributed necessary resource for Iu connects.
Wherein, initial UE message is a RANAP message.In RNC, the SCCP of RANAP request lower floor sends initial UE message, and sets up the SCCP connection; The SCCP of SCCP among the RNC in SGSN sends connection request (CR, Connection Request) message, and initial UE message is packaged into data, is carried in this connection request message; After SCCP among the SGSN receives connection request, connect the request of foundation, then return a connection and confirm (CC, Connection Confirm) message to RNC if accept SCCP.
Above-mentioned steps 303～step 304 connects the process of setting up for Iu.
So far, signaling successful connection between UE and the SGSN is set up, and can be connected at this between UE and the SGSN and submit mutual trust and make message.
Signaling is connected and sets up between UE and SGSN, and it is that RANAP signaling between RNC and the SGSN connects that Iu connects, and is used for transmitting mutual NAS signaling message of UE and SGSN and the RANAP message relevant with calling at the Iu interface.RNC is when transmission article one NAS message is to SGSN, and RNC sets up Iu with SGSN and is connected.After Iu connect to set up, the mutual NAS message of all RANAP message relevant with this communication activity and UE and SGSN was all used this Iu to be connected and is transmitted.
Fig. 4 is that prior art Iu connects the flow chart of setting up, and in the flow chart shown in Figure 4, adopts SCCP
RNCExpression is arranged in the SCCP entity of RNC, SCCP
SGSNExpression is arranged in the SCCP entity of SGSN, and Iu connects foundation and may further comprise the steps:
Step 400:SCCP
RNCTo SCCP
SGSNSend SCCP connection request (SCCP ConnectionRequest) message, connect to set up SCCP.
When RNC receives article one NAS message from wave point, be article one carry the NAS-PDU data RRM (RRC) message the time, if not setting up Iu between UE and core net is connected, then the request of the RANAP among the RNC SCCP of lower floor sends initial UE message (Initial UE Message), because the NAS message that initial UE message is carried is relevant with calling, therefore, RANAP indicates simultaneously and sets up SCCP be connected between the SCCP among RNC and the SGSN.
Generally, if the length of initial UE message is less than or equal to the length of the data that SCCP connection request message can carry, then initial UE message is carried in the SCCP connection request message and sends to SGSN; If the length of the data that the length of initial UE message can be carried greater than SCCP connection request message, then SCCP connect set up after, the data that initial UE message is carried at SCCP transmit in (SCCP Data Transfer) message and send to SGSN.
RNC can connect for the Iu that is about to set up and distribute the Iu connection identifier, and carry following information in initial UE message: the Service Area Identifier of the current position of UE before initial UE message is passed to SGSN; The positional information of UE is as Routing Area Identifier or Location Area Identification; Being used for indicating the destination of NAS message is the SGSN of packet domain or the domain identifier of the mobile switching centre in the circuit domain (MSC); The Iu connection identifier; And global RNC sign.
Step 401:SCCP
SGSNAfter receiving SCCP connection request message, to SCCP
RNCReturn SCCP and connect affirmation (SCCP Connection Confirm) message.
If carry data in the SCCP connection request message, such as the initial UE message of encapsulation, SCCP
SGSNThe RANAP that the data that receive is submitted to the upper strata handles;
If do not carry initial UE message in the SCCP connection request message, so, at SCCP
RNCAfter receiving that SCCP connects acknowledge message, SCCP
RNCInitial UE message is carried at the SCCP data as data transmits in (SCCP Data Transfer) message, and send to SCCP
SGSNSCCP
SGSNThe RANAP that the data of carrying in the SCCP data transfer messages is submitted to the upper strata handles.
Iu connect sets up successfully after, the mutual RANAP message relevant with this communication activity is connected the transmission of finishing message by the SCCP of foundation between RNC and the SGSN, and use SCCP data transfer messages is carried mutual RANAP message.
If SCCP
SGSNRefusal SCCP connects the request of foundation, SCCP
SGSNTo SCCP
RNCSend SCCP and connect refusal (SCCP Connection Reject) message, set up failure to show that Iu connects.
After RANAP among the SGSN receives initial UE message, for UE creates communication context information, the information of carrying in the storing message, for example the positional information of Iu connection identifier, UE, global RNC identify, and the NAS message of carrying in the initial UE message submitted to more last layer protocol entity, such as GPRS Mobility Management (GMM, GPRS Mobility Management) protocol entity, or session management (Session Management) protocol entity etc.
For R99 and R4 version, the Iu interface based on atm technology and No.7 signalling system (SS7, SignalingSystem7), transport network layer adopts the SCCP/MTP3b agreement; For the Iu interface of R5 version,, consider backwards compatibility though can support the IP transmission technology, therefore continue to use SCCP, introduce M3UA and Stream Control Transmission Protocol simultaneously, like this, make the protocol stack more complicated of Iu interface, the protocol stack of Iu interface is seen shown in Figure 2.Above-mentioned Fig. 4 is based on the Iu interface of prior art Fig. 2 and sets up process.
As seen signaling is connected the method set up between UE and SGSN from above-mentioned existing UMTS: after the RRC successful connection is set up, just set up Iu and connect, finally realize UE and SGSN establishment of connection, processing has like this increased the time that signaling between UE and SGSN is connected foundation.
At present, 3GPP is studying the next generation network after the evolution of UMTS network, and formulates the technical standard of evolvement network, the next generation network after the evolution of UMTS network is abbreviated as evolvement network (Evolved Network) herein.Evolvement network will have a lot of new characteristics, such as: the packet-type business only is provided, and real time business such as voice, visual telephone also adopt the mode of grouping to realize; Realize complete IP network, each node interconnects by IP network in the network, and each portable terminal adheres to distributing IP address, back; Switching and roaming between support and the UMTS network.In addition, evolvement network was had higher requirement to the time of inserting and switch: the time that user access network enters activated state is no more than 200ms; Be no more than 300 milliseconds switching time between the system of real time business; Be no more than 500 milliseconds etc. switching times between the system of non-real-time service, and as seen, evolvement network is the comparison harshness to the time requirement of quick access.
Fig. 5 is the structural representation of the evolvement network of present 3GPP definition, and this evolution network structure is not also finally determined.As shown in Figure 5, evolvement network comprises evolution block core net (Evolved Packet Core) and evolution wireless access network (Evolved-RAN, Radio Access Network).Wherein, three logical functional entities are arranged among the EvolvedPacket Core, Mobility Management Entity (MME, MobilityManagement Entity), user entity (UPE, User Plane Entity) anchor point (Inter AS Anchor) and between connecting system, MME is used to realize mobile management, UPE is used to realize the processing of packet sessions management and user plane packets data, and Inter AS Anchor is used to realize switching between access, evolvement network and other non-3GPP networks such as the wireless lan (wlan) of evolvement network and outside PDN and roaming etc.; Evolved-RAN realizes the function of air interface, and the interface between Evolved RAN and the EvolvedPacket Core is the S1 interface, and the interface of Inter AS Anchor and PDN is the Gi interface.At present, the undefined S1 interface of how realizing of 3GPP.Among the present invention, the terminal equipment unification that user in the evolvement network is used is called travelling carriage (MS, Mobile Station).
As shown in Figure 5, MME and UPE are arranged in same node, in addition, MME and UPE can be respectively as node independently, perhaps UPE and Inter AS Anchor are positioned at same node.
With the UMTS network class seemingly, MS is with before evolution block core net is communicated by letter, also needing to set up signaling with evolution nuclear grouping heart net is connected, such as: registration, tracing section updating, packet service call or page response etc. after the MS start, after signaling connect to be set up, MS could with the mutual NAS message of Evolved Packet Core.Setting up the process that signaling connects comprises: MS is connected foundation with AS between the Evolved RAN, and Evolved RAN is connected foundation with S1 between the Evolved Packet Core, among the present invention Evolved RAN is connected with signaling between the Evolved Packet Core to be called S1 and to connect.At present, 3GPP also proposes how to set up the solution that signaling is connected between MS and evolution block core net, does not also propose the solution that S1 connects foundation certainly.
Because evolvement network is relatively harsher to the time requirement of quick access, if continue to adopt among the existing UMTS signaling between UE and SGSN to be connected the method for foundation, realize that MS and evolution block core net set up signaling and be connected, can cause the time of MS access network longer, can not satisfy the harsh requirement that evolvement network proposed turn-on time.
In addition, evolvement network will adopt the IP technology fully, promptly adopt bearer network based on the IP technology that interconnection between the equipment is provided, at this moment, and between the core net, between core net and the Access Network, all are IP transmission networks between Access Network and the Access Network.Under the situation of the employing all-IP transmission network of evolvement network, evolvement network is relatively harsher to the time requirement of quick access, realize the S1 interface if continue to adopt the Iu protocol stack of the interface of complexity among the existing UMTS, the treatment effeciency of S1 interface will be reduced, thereby, if continue to adopt among the existing UMTS signaling between RNC and SGSN to be connected the method for foundation, realize establishment of connection between evolution wireless access network and evolution block core net, can cause to satisfy evolvement network requirement turn-on time.

In theory, if with the processing time of a piece of news, such as transmission, receive, the processing time that message transmits is as a chronomere, in the prior art, referring to Fig. 3, the signaling connection procedure needs 5 chronomeres, and among the present invention, referring to Fig. 6, because step 601a and step 601b are parallel processings, step 602a and step 602b almost are parallel processings, therefore, the present invention realizes that being connected the process of foundation between travelling carriage and evolution block core net only needs 3 chronomeres, reduced by 40% time of implementation than art methods, shortened greatly between MS and evolution block core net and be connected the time of setting up, satisfied evolvement network requirement turn-on time.
Specifically describe the method that signaling between evolution wireless access network of the present invention and evolution block core net is connected foundation below.
Fig. 7 is a S1 protocol stack of the interface schematic diagram one in the evolvement network of the present invention, and Fig. 8 is a S1 protocol stack of the interface schematic diagram two in the evolvement network of the present invention, below these two kinds of S1 protocol stacks of the interface is described.
As shown in Figure 7 and Figure 8, two kinds of schemes adopt identical chain of command agreement, wireless network layer signaling protocol (RNL Signaling) is by the UDP/IP carrying, and RNL Signaling is used to represent the chain of command agreement of wireless network layer in the present invention, and concrete title is by the definition of 3GPP tissue.RNL Signaling realizes the signaling control relevant with wireless network, finish between S1 interface signaling establishment of connection and release, evolution wireless access network and the evolution block core net signaling message alternately, the foundation in the transmission of NAS message and user face data tunnel and release etc.;
The tunnel protocol of user's face has two kinds, and a kind of is to continue to use the GTP-U tunnel protocol, and another kind is to use Generic Routing Encapsulation (GRE, Generic Routing Encapsulation) tunnel protocol.Wherein, use the GTP-U tunnel protocol, help realizing the switching between evolvement network and the UMTS network; And, therefore use the gre tunneling agreement because the gre tunneling agreement is widely used in the Internet of ietf definition network, make that the S1 interface is more general.Among Fig. 7, the transport network layer of user's face is same as the prior art, adopts the GTP-U/UDP/IP protocol stack.Among Fig. 8, the transport network layer of user's face adopts the gre tunneling agreement, adopts the GRE/UDP/IP protocol stack.In addition, in Fig. 7 and Fig. 8, RNL UP is the user plane protocol of wireless network layer, specifically adopts what user plane protocol, such as the Iu UP that still adopts transparent mode, 3GPP is undefined at present, because the agreement of wireless network layer and transport network layer can independent development, and the agreement realization of paying close attention to transport network layer of the present invention, therefore, which kind of agreement RNLUP adopts, and is irrelevant with the inventive method.
Compare with Fig. 2, among Fig. 7 and Fig. 8, the chain of command transport network layer of evolvement network S1 interface has replaced SCCP/M3UA/SCTP by UDP, wireless network layer protocol data by UDP/IP carrying upper strata, simplify protocol stack structure, thereby reduced the implementation complexity of equipment on interface, improved the treatment effeciency of S1 interface.
Fig. 7 and two kinds of S1 protocol stacks of the interface shown in Figure 8, the inventive method is all supported, specifically describe the method that is connected foundation based on signaling between the evolution wireless access network of S1 protocol stack of the interface of the present invention and evolution block core net below, Fig. 9 is that S1 of the present invention connects the flow chart of setting up, need to prove, the S1 establishment of connection can be initiated by the evolution wireless access network, also can be initiated by evolution block core net, and shown in Figure 9 is to connect the process of setting up by the S1 that the evolution wireless access network is initiated.When the evolution wireless access network receives article one NAS message from MS, and check out that this MS does not also set up signaling at the S1 interface and connects, therefore the signaling that need set up S1 interface between evolution wireless access network and evolution block core net is connected, and specifically may further comprise the steps:
Step 900: the evolution wireless access network is that S1 connect to distribute unique connection identifier, sends to evolution block core net to be used to initiate S1 and to connect the connection of setting up and set up request message.
Connect and to set up request message and finish transmission by the UDP/IP of lower floor, this connection is set up and is carried following information in the request message at least:
Type of message: be used to identify the type of this message for connecting the request of foundation;
Connection identifier: be used for connecting in the signaling of a MS of S1 interface unique identification;
Access network node sign: be used for identifying the evolution wireless access network, device identification with the equipment of evolution block core net interconnection, such as, when the equipment that interconnects with evolution block core net in the evolution wireless access network had only an E-NodeB, access network node was designated ID number of this E-NodeB;
Positional information: be used to identify the MS current position information, this positional information can be tracking area identification (TAI, Tracking Area Identity), cell ID, Service Area Identifier, the perhaps combination in any of above-mentioned each positional information is as long as express the current location information of MS;
NAS-PDU data: the NAS message that is packaged into the NAS-PDU data that the evolution wireless access network receives.
Connection is set up and be can further include user ID in the request message, and this user ID can be permanent sign such as IMSI International Mobile Subscriber Identity (IMSI), or provisional sign such as packet TMSI (P-TMSI) etc.
Step 901: evolution block core net receive connect set up request message after, for MS creates the communication context that the S1 interface signaling connects, store this connection and set up connection identifier, access network node sign and the positional information of carrying in the request message, and the NAS-PDU data of carrying in the message are submitted to upper-layer protocol handle; Evolution block core net returns connection establishment response message to the evolution wireless access network, carries to connect in message and sets up successful successful sign.
If evolution block core net can not connect for MS sets up the S1 interface signaling, evolution block core net carries failure cause in connection establishment response message.Perhaps, evolution block core net returns an expression S1 interface signaling to the evolution wireless access network and connects the special message of setting up failure, sets up refuse information such as connection, and sets up in this connection and to carry failure cause in the refuse information.
Connection establishment response message or connection are set up in the refuse information, should carry following information: be used to identify the type of this message for connecting the connection identifier information of setting up the message type information of request responding message and being used to carry the connection identifier that receives.MS for the MS of activated state, all carries described connection identifier in mutual all RNL Signaling message, to distinguish different MS between evolution wireless access network and evolution block core net after the signaling successful connection of S1 interface is set up.
Described upper-layer protocol is the responsible protocol entity of handling the mobile management function, or the responsible protocol entity of handling session management etc.
The S1 that is initiated by evolution block core net connects and sets up process and method shown in Figure 9 is similar, no longer is described here.
Flow process shown in Figure 9 be at the S1 interactive interfacing when calling out relevant signaling message, the S1 that sets up at the S1 interface connects, the method that is connected with signaling between realization evolution wireless access network and evolution block core net.In addition, the S1 interactive interfacing with call out irrelevant signaling message, and during paging request message, do not need to set up S1 and connect.Figure 10 is that the present invention passes through the flow chart that the S1 interface is initiated paging, as shown in figure 10, with the paging request is example, the S1 protocol stack of the interface that adopts the present invention to propose, evolution block core net send the method for paging request message to the evolution wireless access network, receive the downlink data of certain MS or professional when setting up request at evolution block core net, and this moment, MS was in idle condition, so, evolution block core net meeting paging MS comprises:
Step 1000: evolution block core net sends paging request message to the evolution wireless access network, and this paging request message is finished transmission by the UDP/IP of lower floor, carries following information in this paging request message at least:
Type of message: the type that is used to identify this message is the paging request;
User ID: can be permanent sign such as IMSI, or provisional sign such as P-TMSI etc.;
The paging reason: be used to identify the reason of paging, as speech called, session is called;
Positional information: be used to identify the evolution wireless access network at described certain MS of which area paging, positional information can be TAI, cell ID, Service Area Identifier, or the combination in any of above-mentioned each positional information.
Set up the business of what type if evolution block core net can be known this paging requirement, so, can further include type of service in the paging request message.
After the evolution wireless access network receives paging request message, described certain MS of paging in the zone of appointment.Usually, the evolution wireless access network sends beep-page message to this MS on paging channel, and how the evolution wireless access network specifically sends beep-page message to this MS, does not belong to category of the present invention, repeats no more here.
