Embodiment Construction

[0063] refer to image 3 , Embodiment 1 of the present invention provides a network-side processing method in the process of user handover, the method is suitable for the second network and the UE synchronously delete the bearer context, the UE accesses the first network, and starts the ISR in the Attach process, the method Specifically include:

[0064] Step 301, the UE sends an Attach Request message to the MME in the first network, and the message carries a packet temporary mobile subscriber identity (Packet Temporary Mobile Subscriber Identity, P-TMSI), a routing area identifier Old RAI, and an ID indicating whether the UE supports ISR capability information.

[0065] Step 302, the MME sends an Identification Request message to the SGSN in the second network according to the P-TMSI and the Old RAI, and asks for the ISR capability and the IMSI; specifically, the following implementation methods are possible:

[0066] 1) Add an information element requesting the ISR capabi...

Abstract

The invention discloses a network side processing method during user switching, which is applicable to UE (user equipment) which does not bear the context. The method comprises the following steps that: after a first network receives an attach request message sent by the UE, the first network determines that the UE starts ISR between the UE and a second network, and sends information of instructing the UE to start the ISR (idle-mode signaling reduction) between the UE and the second network to the UE. The technical proposal provided by the invention can start the ISR in attach flow. For an E-UTRAN network, a mobility management network element is MME; and for a GERAN/UTRAN network, a mobility management network element is SGSN.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to a network side processing method, network element equipment and network system during user switching. Background technique [0002] The core network of the wireless evolved network mainly includes three logical functional entities: the Mobility Management Entity (MME), the Serving Gateway (S-GW), and the Packet Data Network Gateway (PDN-GW). Among them, MME is a mobile management entity, responsible for non-access stratum (Non Access, NAS) signaling encryption, roaming, tracking and other functions, assigning user temporary identity, security functions, etc., it corresponds to the current Universal Mobile Communication System (Universal Mobile Communication System) The control plane part of the GPRS Service Support Node (Serving GPRS Support Node, SGSN) inside the Telecommunications System, UMTS). The S-GW is responsible for the local mobility anchor point and the mobilit...
