Description
Technical field
The present invention relates to communication technical field, relate in particular to the report method and the system of local Internet protocol (IP, the Internet Protocol) network access capacity of a kind of Home eNodeB.
Background technology
In present third generation digital communication (3G) network architecture, the base station links to each other with core net by the Iu interface, and the IP carrying is adopted in the signaling transmission of Iu interface; Wherein the Iu interface is the interface between wireless access network and the core net in the 3G system.In present Long Term Evolution (LTE, the Long Term Evolution) network architecture, the network configuration flattening links to each other by the S1 interface between wireless access network and the core net; Wherein, the S1 interface is the interface between wireless access network and the core net in the LTE system.
Home eNodeB is a kind of small-sized, lower powered cellular basestation, is mainly used in indoor place such as family and office and gains the name.One of its effect is the replenishing of indoor covering, for the user provides speech and data, services as Cellular Networks.Home eNodeB has low cost, supports plug and play, by characteristics such as broadband access, low-power, use single-mode terminal.Home eNodeB can insert in the 3G and the LTE network architecture.For the ease of Home eNodeB is managed, reduce influence to core net, the family base station system wireless access network has been introduced femto gateway.Wherein, the Home eNodeB in the 3G network framework must link to each other with core net by femto gateway.And the Home eNodeB in the LTE network architecture might not link to each other with core net by femto gateway, it has two kinds of connected modes: first kind is that Home eNodeB directly links to each other with core net, specifically be with core net in the network element Mobility Management Entity directly be connected, the network element Mobility Management Entity here is generally service general grouping service wireless support node (SGSN, Serving GPRS Suport Node); Second kind is that Home eNodeB links to each other with core net by femto gateway, specifically be by femto gateway with link to each other with network element Mobility Management Entity in the core net, the network element Mobility Management Entity here is generally Mobility Management Entity (MME, Mobility Manegement Entity).In the LTE home base station network framework that adopts second kind of connected mode, interface between two network elements has appearred: interface between the interface between Home eNodeB and the femto gateway, femto gateway and the MME, these two interfaces are all represented with S1-MME in the prior art, for the ease of difference, can still the interface between Home eNodeB and the femto gateway be designated as the S1 interface, the interface between Home eNodeB and the femto gateway is designated as the S1-A interface; Interface between femto gateway and the MME is designated as the S1-B interface, and these three interfaces all adopt the signaling process of S1 interface in the prior art.In 3G home base station network framework, after Home eNodeB and femto gateway are set up stream control transmission protocol (sctp) and be connected, register to femto gateway by the registering family base station flow process.From the Home eNodeB angle, this moment, femto gateway was a core network element, after the SCTP of family base station and femto gateway was connected foundation, first reciprocal process between Home eNodeB and the femto gateway was exactly the process of Home eNodeB to the femto gateway registration.In the application protocol of the Iu of 3G network framework interface, it is the UE initial message that subscriber equipment (UE) is initiated professional article one message to core net, does not have other signaling process to finish the information interaction of Home eNodeB and core net before.In the LTE network, when the base station be connected with SCTP between MME set up after, base station and core net are set up the information exchange that message is finished base station and core net by the S1 interface.
At present, UE is linked in the Internet network of network framework by macro base station, it is to pass through core network element that the IP that UE sends wraps in the 3G home base station network framework, be GPRS gateway support node (GGSN, Gateway GPRS Supporting Node), GGSN sends to the external IP network, in LTE home base station network framework is to send to outside IP network by grouped data network gateway (PGW, PDN Gateway).It is a functions peculiar that is different from macro base station of Home eNodeB that the local IP of Home eNodeB inserts (LIPA, Local Ip Access) function, and Home eNodeB has had this LIPA function, and UE just can directly visit external network by Home eNodeB.In order to realize Home eNodeB LIPA function, in LTE home base station network framework, need be called local PGW (L-PGW in the function of integrated PGW network element of family's inside of base station and gateway (SGW, Serving Gateway) network element, Local PGW) and local SGW (L-SGW, Local SGW).After UE was linked into Home eNodeB, user's face IP packet that UE sends directly sent among the Internet by L-PGW or the local GGSN (L-GGSN, Local GGSN) in the Home eNodeB.Realize that the signaling process of chain of command still need be handled at the MME/SGSN of core net in the Home eNodeB LIPA process.When UE request LIPA is professional, initiates Non-Access Stratum (NAS) message request to core net and set up packet data network (PDN, Packet Data Network) connection, carry the LIPA service identification in the message, such as the APN that is used for the LIPA business; After MME/SGSN receives this message, need send carrying to the L-SGW/L-SGSN that is positioned at Home eNodeB inside and set up request message.After core-network side network element SGSN/MME received this message, the information of obtaining from message learnt that this message is to initiate the LIPA business.Because in the LIPA access service, the IP address of UE is to be distributed by the L-PGW in the Home eNodeB, message is set up in L-PGW/L-GGSN and L-SGW transmission carrying that MME/SGSN needs to be somebody's turn to do in Home eNodeB.
Yet, in the present network architecture, because core network element SGSN/MME is the specifying information of not knowing Home eNodeB, that is to say, core net does not know whether the IP address of Home eNodeB and Home eNodeB have the ability of supporting the LIPA business, therefore, have two aspect problems in the prior art: on the one hand, core net can't judge whether to set up carrying into the LIPA service request of Home eNodeB initiation; On the other hand, if MME/SGSN accepts the LIPA service request that Home eNodeB is initiated, be the carrying of sending to L-SGW and L-PGW/L-GGSN can't be set up request message to be routed to Home eNodeB.
In sum, as seen to realize the LIPA function of Home eNodeB, core network element MME/SGSN need obtain the IP address whether Home eNodeB supports the ability information of LIPA business, Home eNodeB, and under the situation that has femto gateway to dispose, femto gateway need obtain the Home eNodeB that is attached thereto and whether have ability and the Home eNodeB sign of supporting LIPA, and these information are reported to core net.But, in existing 3G and LTE network family base station network framework, whether Home eNodeB does not have to support the ability of LIPA to notify family's base-station gateway and core network element MME/SGSN, has caused core network element and femto gateway can't judge whether Home eNodeB supports the IP address information of the ability information of LIPA business, Home eNodeB.When having disposed femto gateway in the network, SGSN/MME can't be properly routed to Home eNodeB through femto gateway for the message that this UE creates user plane bearer, so there is significant limitation in prior art.
