Device.
Background technology
Along with wireless communication technology and the continuous evolution of standard, mobile Packet Service has obtained huge development,
The data throughput capabilities of unit/terminal is constantly promoting.With Long Term Evolution, (Long Term Evolution is called for short
LTE), as a example by system, can support that in 20M bandwidth the data of descending maximum rate 100Mbps are transmitted,
In LTE (LTE Advanced) system of follow-up enhancing, the transfer rate of data will promote further,
Even can reach 1Gbps.
The growth of terminal data portfolio expansion type, makes all of Internet resources the most unable to do what one wishes, especially
It is that the thing followed is in the case of a new generation communication technology such as 3G, LTE also cannot extensively arrange net
User rate and traffic demand cannot meet the variation of Consumer's Experience.How to prevent and change this situation be
The problem that operator must take into, on the one hand needs to accelerate popularization and the network design of new technique；The opposing party
Face, it is desirable to be able to by strengthening existing network and technology, to reach fast lifting network performance
Purpose.It is known that at third generation partner program (The 3rd Generation Partnership
Project, is called for short 3gpp) outside the radio network technique that provides, the most commonly used wireless office
Territory net (Wireless Local Area Network is called for short WLAN), is based especially on Electrical and Electronic
SE's (Institute of Electrical and Electronics Engineers is called for short IEEE) 802.11
The WLAN of standard has been widely used in focus access and has covered in family, enterprise even the Internet
Lid.The technical specification wherein proposed by WiFi alliance (Wi-Fi Alliance) is most widely used, therefore actual
Middle WiFi network often follows wlan network based on IEEE 802.11 standard to be equal to, and obscures not causing
In the case of, the follow-up WiFi module that is also adopted by is to describe the wireless receiving and dispatching supporting WLAN in network node
And processing module.
Under this premise, some operators and company have been proposed that WLAN and existing 3gpp network
Merge, it is achieved joint transmission, to reach load shunting and to improve the purpose of network performance.3gpp SA2
Passed through access network discovery and select function (Access Network Discovery Selection Functions,
It is called for short ANDSF) scheme, it is provided that a kind of is that terminal selects target access network according to carrier policy
Pattern.
Access network discovery and selection function (Access Network Discovery and Selection
Function, referred to as ANDSF) as access anchor point, it is possible to realize Intelligent network-selecting, by network with
Terminal mutual, it is achieved effective shunting of network insertion, meets the operation direction of following multi-network cooperative.
ANDSF generates strategy, and helps terminal use to select the network formats most preferably accessed, it is achieved multiple access side
Working in coordination with of formula.
In prior art, ANDSF proposes at Release-8.When UE network to be selected is registered
Time, if there is 3GPP access network and non-3 GPP access network simultaneously, EPS (Evolved Packet System,
Evolved packet system) can provide available by ANDSF to UE according to positional information current for UE
Access network information, or inter-system mobility strategy (Inter-System Mobility Policy, referred to as
ISMP), UE uses the information that ANDSF provides, and selects suitable access network to register.If with
Time there is multiple non-3 GPP access network, EPS can pass through ANDSF according to positional information current for UE
Routing policy (Inter-System Routing Policy, referred to as ISRP), UE between UE offer system
The information using ANDSF to provide, selects suitable access network to shunt.ANDSF is connect by S14
Mouth is connected with UE, and this interface uses open mobile alliance device management (Open Mobile Alliance
Device Management, referred to as OMA DM) agreement.
In prior art, ANDSF can solve 3GPP and be switched to the access network selection problem of non-3 gpp.
Also the shunting routing problem of multi-access terminal can be solved, such as: possess and activate IP stream migration ability
UE (IP Flow Mobility capable UE, referred to as IFOM capable UE), possess and swash
Live multiple access PDN concatenation ability UE (Multiple Access PDN Connectivity capable UE,
Referred to as MAPCON capable UE), possess and activate the UE of seamed WLAN shunt ability
(Non-seamless WLAN offload capable UE, referred to as NSWO capable UE) divides
Stream routing problem.
ANDSF is mutual (interworking) scheme of a WLAN based on core net, not
In view of the impact on access network, additionally due to ANDSF is the scheme of a relative quiescent, it is impossible to very well
Situation about dynamically changing network load and channel quality adapts to.Therefore also carry out in 3gpp access network
WLAN interworking discusses.In the wireless interoperability of R12WLAN/3gpp, perform WLAN
The rule of shunting and the mechanism of triggering are introduced into.
In the wireless interoperability of 3GPP R12WLAN/3GPP, the WLAN introducing RAN auxiliary divides
Stream solution, the configuration parameter of WLAN shunt is transmitted by 3GPP base station by broadcast or unicast messages
To terminal, terminal carry out from 3GPP to WLAN according to the WLAN shunt configuration parameter received or
The shunting judgement of WLAN to 3GPP.
But, it is real-time that core net mechanism and the auxiliary information mechanism from wireless network can not be supplied to network side
Ground uses load and channel condition thus merges use Radio Resource.It addition, from the data of same bearer
Can not transmit on 3gpp and WLAN link simultaneously.Therefore, the need of WLAN Yu 3gpp system integrating
Ask and again proposed in 65 plenary sessions of RAN (wireless access network).
Comparing the WLAN shunt scheme depending on strategy and triggering the most after deliberation, RAN level gathers
WLAN Yu the 3gpp system integrating closed, it is allowed to WLAN accesses 3GPP access network, it is allowed to data are same
Time in WLAN and 3gpp network transmission, the quality current based on channel and the service condition of system resource,
It is scheduling in real time, therefore improves user Qos (service quality) and entire system capacity.
Application, and the WLAN shunt solution of R12RAN auxiliary is had been obtained at present due to ANDSF
Certainly scheme also has been completed standardization, after introducing WLAN and 3gpp network close coupling, exists as follows
Problem: from the point of view of UE, how to avoid the conflict between rule, the selection how carrying out network does not also have
Determine；For network side: need to consider the UE of R13 on strategy, it is also required to the UE of compatible R12 simultaneously.

Described in one, and subsequent applications example, here is omitted.
Following application example illustrates as a example by LTE system, 3G and 5G system is suitable for the most simultaneously.
Application example one
Present example provides a kind of method that UE selects network, in this example, rule is that close coupling is preferential,
By message informing UE, it supports close coupling, as it is shown on figure 3, comprise the following steps to access network:
Step S102, eNodeB (evolved node B) sends system message, contains support in message
Tightly coupled instruction information；
Instruction information can be a newly-increased cell, can be described as close coupling and supports indication information element, and value is
Enumeration type (TRUE, FALSE), TRUE represents support close coupling, FALSE represent do not support tight
Coupling, span can also be (TRUE), comprises this cell and represents support close coupling, does not comprise table
Show and do not support close coupling.
Step S104, UE receives system message, knows that system supports close coupling, and UE judges self to support
Close coupling, according to the rule that the close coupling set is preferential, UE selects 3GPP network, sends out to eNodeB
Send RRC to ask message, request message comprises the tightly coupled information of employing；
In this example, UE self supports that close coupling includes: this UE has close coupling ability and this UE
Allow to use WLAN (such as, interface being supported the intelligent switch of WLAN is in opening).
UE access network has two ways: accessed by 3GPP, or is directly accessed by WLAN,
If accessed by WLAN, just cannot use close coupling, so have to lead to when close coupling is preferential
Cross 3GPP to access, the most further judge whether use close coupling or do not use close coupling to transmit number
According to.
The preferential rule of close coupling can be that UE static state setting in advance is good, or can also be to pass through interface
Manually carry out selecting.
Step S106, eNodeB sends RRC to UE and configures message, comprises close coupling parameter in message,
Such as AP (Access Point, access point) mark or AP address；
Close coupling parameter can also include that multisystem is tightly coupled and enable instruction.
Step S108, UE carries out accessing the foundation of 3GPP resource requirement, returns response to eNodeB and disappears
Breath.
If UE has accessed other system, then after judging according to said method, UE can also switch to
3GPP system.
Application example two
Present example provides the method that another kind of UE selects network, in this example, rule is that close coupling is preferential,
Access network is by sending its support close coupling of channel quality parameter message informing UE, as shown in Figure 4, including
Following steps:
Step S202, eNodeB sends system message, contains close coupling channel quality parameter in message,
Represent that access network supports close coupling；
Step S204, UE judges self to support close coupling, and setting rule is that close coupling is preferential, and measures
Channel quality (LTE system channel) be better than system message send close coupling channel (wlan system
Channel) mass parameter, then UE selects 3GPP network, sends RRC to eNodeB and asks message,
Request message comprises the tightly coupled information of employing；
Measure if close coupling channel (wlan system channel) quality that system message sends is better than UE
Channel quality (LTE system channel), then UE select wlan system access.
This example increases the judgement to channel quality and is to ensure that service quality.
Step S206, eNodeB sends RRC to UE and configures message, comprises close coupling parameter in message,
Such as AP mark or AP address；
Step S208, UE carries out related resource foundation, returns response message to eNodeB.
Application example three
Present example provides the method that another kind of UE selects network, in this example, rule is that close coupling is the most excellent
First, by message informing UE, it supports close coupling, as it is shown in figure 5, comprise the following steps to access network:
Step S302, eNodeB sends system message, contains the tightly coupled instruction information of support in message；
Instruction information is a newly-increased cell, and entitled close coupling support indicates, and value is enumeration type
(TRUE, FALSE), TRUE represents support close coupling, and FALSE represents and do not supports close coupling, takes
Value scope can also be (TRUE), comprises this cell and represents support close coupling, does not comprise expression and does not supports
Close coupling.
Step S304, UE judges self to support close coupling, according to the rule that the close coupling set is the most preferential,
UE sends information request to ANDSF server, and ANDSF server returns ANDSF rule, UE
The ANDSF rule sent according to ANDSF server carries out network selection.
