Network device addressing method, apparatus and system

Abstract

The present invention discloses a network device addressing method, apparatus and system, which relates to the field of communication, and can realize a addressing of a network device when a user is roaming between a 2 / 3G network and a 4G network. The addressing method comprises: an InterWorking Function (IWF) according to a Integrated Services Digital Network (ISDN) number of mobility management network element constructs a host name of mobility management network element; the IWF sends a request message to a Home Subscriber Server (HSS); wherein the request message includes the host name of mobility management network element; the IWF after receiving a response message sent by the HSS, obtains the HSS ISDN number according to the host name of the HSS, and sends the HSS ISDN number to the mobility management network element. The present invention is used for roaming between a 2 / 3G network and a 4G network to the user.

Description

technical field [0001] The present invention relates to the communication field, in particular to a network device addressing method, device and system. Background technique [0002] GPRS (General Packet Radio Service) in 2 / 3G (The Second Generation Partnership Project (2G for short) / The Third Generation Partnership Project (3G for short)) serves general packet radio services In the service) network, SGSN (Serving GPRS Support Node, serving general packet radio service support node) accesses HLR (Home Location Register, home location register) through the Gr interface based on the MAP protocol, and each network element in the GPRS network Nodes are addressed using ISDN (Integrated Services Digital Network) numbers; while in the evolved 4G (Fourth Generation Partnership Project) LTE (Long Term Evolution, Long Term Evolution) network, MME (Mobility The Management Entity (Mobility Management Entity) accesses the HSS (Home Subscriber Server, Home Register) through the S6a inter...

Problems solved by technology

[0003] However, since the IWF is deployed in the LTE network, and if it is necessary to obtain the ISDN number or domain name / host name of the SGSN / HLR of the operator's GPRS network, it is necessary to pre-configure the ISDN of the operator's SGSN / HLR in the IWF Therefore, when the SGSN / HLR of the GPRS network of other operators expands, the IWF may not be notified, that is, these expanded SGSN / HLRs are not configured in the IWF The corresponding relationship between the ISDN numbers of these SGSN / HLR and the domain name / host name, thus causing the users on these SGSN / HLR to be unable to roam
