Description
Technical field
The present invention relates to moving communicating fields, and in particular to a kind of wireless access capability report method and base station, strategy control
Method and system processed.
Background technology
In order to keep 3-G (Generation Three mobile communication system) in the competitiveness of the communications field, provide to the user rate faster, time delay
Lower, more personalized mobile communication service, meanwhile, reduce the operation cost of operator, 3GPP (3rd Generation
Partnership Project, third generation partner program) standard working group is just being dedicated to evolved packet system (Evolved
Packet System, abbreviation EPS) research.
The operator for leading to dispose 3GPP networks originally that pours in of a large amount of large-data operation in recent years experiences very greatly
Flash pressure, the free WLAN of frequency range (Wireless Local Area Network, WLAN) technology be continuously improved
Air interface transmission rate attracted 3GPP network operators' note that spread spectrum that operator wants to by means of WLAN eats dishes without rice or wine to hold
Amount, and ensure user experience on this basis.At present, WLAN is to be independent wireless access technology to be linked into 3GPP cores
Net, this causes 3GPP network operators to need to dispose additional network element WLAN to be supported to access, it is therefore desirable to have additional operation
Into original operation and maintenance.Therefore consider to merge LTE with WLAN, can both expand wireless processing capacity, it is also ensured that
To customer service in QoS (Quality of Service, service quality), mobility, safe and energy saving etc. requirement.Its
The fusion mode of middle LTE and WLAN a kind of starts to be received by operator, i.e.,：LTE is as main access, the access control of terminal, mirror
It weighs certification etc. and completion is all accessed by LTE；WLAN is accessed as subordinate, can expand bandwidth of air-interface, and reaching reduces LTE loads.
Fig. 1 gives the configuration diagram of this deployment way.
As shown in Figure 1, entire EPS system is divided into wireless access network and core net two parts.In the core network, it contains and returns
Belong to client server (Home Subscriber Server, referred to as HSS), mobility management entity (Mobility

Take gateway；
Packet data gateway, is the gateway of evolution system and the exterior packet data network, it is connected to internet
On packet data network, it is responsible for the distribution of Internet protocol (Internet Protocol, referred to as IP) address, the meter of terminal
Take the functions such as function, grouping packet filtering, policy control；
Packet data network, is the IP operation network of operator, which is provided to the user by the core net of operator
IP is serviced；
Policy charging rule functional entity is to be responsible for providing charging control, online diameter credit control, thresholding control in evolution system
The server of system, service quality (Quality of Service, referred to as QoS) strategy aspect rule；
Ordinary base station (NodeB/RNC, Radio Network Control or eNodeB), is mainly responsible for wireless signal
Transmitting-receiving, by air interface and terminal contact, manage the radio resource of air interface, scheduling of resource, access control；
Joint base station refers to being integrated with the ordinary base station of above-mentioned WLAN access functions, in addition to the function of ordinary base station, goes back
The data traffic eated dishes without rice or wine can be diverted in WLAN accesses, and wireless resource management, resource tune are performed to two kinds of access technologies
The functions such as degree, access control.
Above-mentioned Serving GPRS Support Node is the SGSN upgraded, can support the S4 interfaces between gateway, and
Intercommunication is carried out using GTPv2 agreements between mobility management unit.And the ps domain net for the SGSN for supporting 3G core nets
Network framework and Fig. 1 are different.SGSN is connected with MME using gn interface at this time, and intercommunication uses GTPv1 agreements.SGSN cannot be with
Gateway is connected, and Gateway GPRS Support Node (Gateway GPRS Support Node, abbreviation are connected to by gn interface
GGSN) directly it is grouped data network access.
In the prior art, policy charging rule functional entity can formulate different chargings and QoS plans according to different situations
Slightly, such as according to different access technologies, according to location information of UE access etc. different strategy is formulated, and will be under this strategy
Corresponding network element, such as PGW/GGSN, base station etc. are dealt into, these strategies are performed by respective network elements.Formulate these strategy when
It waits, policy charging rule functional entity does not consider the ability of wireless net member, this is primarily due in the prior art, wireless net member
Ability be mainly it is directly related with access technology, ordinary base station is merely able to support a kind of access technology.However, as introducing
Joint base station, access technology and base station ability are no longer one-to-one relationships.It can cause in this way, policy charging rule function is real
The strategy that body is formulated is not accurate enough, it is impossible to be completely adapted to the framework of this new introducing.In addition, related plan is formulated for UE at present
When slightly, the abilities of UE in itself are only only accounted for, do not consider the ability of wireless access network element.
In addition, how to determine that there has been no specific definition by data distribution to WLAN accesses to joint base station at present.
