System and method for determining terminal mobility management type

Abstract

The invention discloses a method and a system for determining the types of terminal mobility management, wherein, the mobile terminal reports information to a network and the reported information comprises mobility ability information supported by the mobile terminal. The network determines the types of mobile terminal mobility management according to the reported information and the mobility ability information supported by the mobile terminal. With the embodiment of the invention, when the mobile terminal accesses the network through different access processes, the network can determine the corresponding types of mobility management according to the mobile terminals connected to the network through different access processes.

Description

technical field [0001] The present invention relates to the communication field, in particular to the technology for determining the type of terminal mobility management. Background technique [0002] The WiMAX network is a wireless network based on the standard IP protocol, and its networking structure is as follows: figure 1 As shown, it includes MS (mobile terminal), ASN (Access Service Network, service access network) and CSN (Connectivity Service Network, service connection network) three parts. The MS accesses the network through the ASN, and the CSN ensures that the MS obtains a reliable IP communication connection. [0003] At present, there are many types of MS. According to the mobility capabilities they support, they can include MSs that only support Simple IP (simple IP) capabilities, MSs that only support MIP (Mobile IP, mobile IP) capabilities, and support SIP capabilities at the same time. and MIP capable MS. [0004] When the MS supports the Simple IP capa...

Problems solved by technology

When the network side receives the DHCP request and the MIP request sent by the MS, the mobility management type of the MS cannot be determined according to the prior art

[0013] 2. When the MS has the ability to support MIP, the MS sends a MIP registration request, and then sends a DHCP request to obtain the corresponding host configuration information. At this time, using the prior art 1, the network side cannot determine the mobility of the MS Sex management type is CMIP or PMIP

[0014] 3. When the MS requires both CMIP management and PMIP management, the specific type of the MS cannot be configured on the network side

[0019] Since the expansion of the EAP protocol on the air interface of IEEE802.16 is inconvenient and cannot guarantee a reliable response, the network side cannot negotiate the ability of the MS to support IP through the existing technology 3
