Description
Technical field
The present invention relates to wireless communication technique, particularly relates to a kind of method and system for selecting network priority.
Background technology
Machine To Machine (M2M, Machine to Machine) technology refer to all technologies that connection is established between machine and
Means.At present the machine quantity in the whole world than people quantity more than it is very much, it can thus be anticipated that to before the good market of M2M technologies
Scape.
In order to effectively utilize mobile network resource, third generation partner program (3GPP, 3rd Generation
Partnership Project) machine type communication (MTC, Machine Type Communication) is proposed, including
The business that M2M, machine communicate people (Machine to Man), its scope of business is far beyond conventional Human To Human
Communication between (H2H, Human to Human), MTC is in access control, charging, security, service quality (QoS, Quality
Of Service), business model etc. makes a big difference with present H2H communication modes.
As shown in Figure 1,3GPP evolved packet systems (EPS, Evolved Packet System) include wireless access network
(such as Universal Mobile Communication System (UMTS) land radio access web (UTRAN, Universal Terrestrial Radio
Access Network), the UTRAN (E-UTRAN, Evolved UTRAN) of evolution, global system for mobile communications/enhanced number
According to speed GSM evolution (GSM/EDGE) Radio Access Network (GERAN, GSM/EDGE Radio Access Network)) and core
Heart net.There are mobile management entity (MME, Mobility in the packet-based core networks (EPC, Evolved Packet Core) of evolution
Management Entity), gateway (SG, Serving Gateway), Packet Data Network (PDN) gateway (PGW, PDN
Gateway), the network element such as home subscriber server (HSS, Home Subscriber Server)；Include in GPRS core nets
The network elements such as Serving GPRS Support Node (SGSN, Serving GPRS Support Node)；Include evolution in E-UTRAN
Node B (eNB, evolved Node B).
User equipment or terminal (UE) may be at one of following two states：One kind is RRC connected states (RRC_
CONNECTED, referred to as connected state)；Another kind is RRC Idle state (RRC_IDLE, referred to as Idle state), in Idle state
UE does not establish wireless heterogeneous networks (RRC, Radio Resources Control) connection with network side, in connected state
UE then establishes RRC with network side and is connected.
UE can be registered to evolved packet system (EPS, Evolved Packet System) service and non-evolution point at the same time
System system (non EPS) service, this is known as combining attachment.The UE of joint attachment has two kinds of operator schemes：Circuit switching/packet is handed over
Change (CS/PS, Circuit Switched/Packet Switched) pattern l and CS/PS pattern 2, under CS/PS patterns 1, UE is used
Way is " under voice centric ", CS/PS pattern 2, UE purposes is " data centric " based on data based on voice.
The enormous amount of MTC user equipmenies, it is thus possible to cause network congestion, in order to avoid network congestion, carried in 3GPP
Go out the mechanism using backoff time, including backoff timer after backoff timer and mobile management after session management.Backoff timer afterwards
Non-Access Stratum (NAS, Non Access Stratum) signaling is generally used by network side, UE is sent in refuse information；Institute
It is the UE for having the function of MTC to state MTC user equipmenies.
Under general congestion scenario, backoff timer (back-off Timer) after MME is produced and run, and refuse to come from UE
Mobile management scheduling request.Except high-priority users, emergency services (Emergency Services) and Mobile terminating call
Outside (the Mobile Terminated Services) business of service, UE should not initiate the mobile management message of other business.
Wireless resource management (RRM, Radio Resource Management) refers to by wireless access network (RAN, Radio
Access Network) distribution to wireless communications path completed and maintenance correlation function, the RRM strategies that network side uses
It can be made choice according to the customizing messages of UE.
MME/SGSN obtains the wireless access of UE from home subscriber server (HSS, Home Subscriber Server)
Technology/frequency of selection priority (RFSP, RAT/Frequency Selection Priority) index information, MME/SGSN will
RFSP values notify corresponding eNB/ base station controllers (BSC, Base Station Controller)/radio network controller
RFSP index informations (are known as user file by (RNC, Radio Network Controller), eNB/BSC/RNC in the ran
Mark (SPID, Subscriber Profile ID for RAT/frequency priority)) it is applied in RRM strategies,
As applied in cell reselection priority setting and cell switch process.Fig. 2 gives MME/SGSN and is sent to eNB/BSC/RNC
The schematic diagram of RFSP index informations.
MME/SGSN can (such as MME/SGSN makes according to the local policy from the received RFSP information of HSS, operator
RFSP), the specific information selecting RFSP index values of network state and UE, i.e. SPID, SPID values are 1-256, wherein：
1-128, represents the specific SPID values of operator；
129-256, expression refer to use value.
Different SPID values correspond to the precedence information of heterogeneous networks, and it is corresponding excellent to be equal to 256 as shown in table 1 for SPID values
First level information is：The carrier wave priority of E-UTRAN is high (high), the carrier wave priority of UTRAN be in (medium), GERAN
Carrier wave priority be low (low).
SPID=256
Table 1
In order to distinguish PS congestions and CS congestions, core net is set using different rear backoff timers, i.e. backoff timer after PS
Backoff timer (CS back-off timer) after (PS back-off timer) and CS.3GPP is provided at present：If PS
Back-off timer are run, and CS back-off timer stop, i.e. PS congestions, CS not congestions, then Idle state UE is resided in
E-UTRAN, UE need to initiate the relevant services of CS, such as voice or short message service (SMS, Short Message Service), this
When UE CS services can be initiated in GERAN or UTRAN with gravity treatment to GERAN or UTRAN.
Find that there are problems with for the prior art in the research to the prior art and practice process：PS congestions, CS are not gathered around
During plug, CS requests cannot be initiated by residing in the UE of E-UTRAN；Or services of the UE in GERAN or UTRAN terminates, return idle
After pattern, using normal cell reselection, E-UTRAN cells are returned in the possible gravity treatments of such UE, and the PS congestions in E-UTRAN do not have also
There is releasing, UE cannot initiate attachment/location updating in E-UTRAN, and UE also can not just receive MT services, in that way it is possible to
Ping-pong occurs between GERAN or UTRAN and E-UTRAN, causes UE power consumptions to increase and influences user experience.
The content of the invention
In view of this, it is a primary object of the present invention to provide a kind of method and system for selecting network priority, avoid
