[0039] Such as figure 1 As shown, the first embodiment of the present invention provides a UE context sharing method, which is applied to a second mobility management unit MME, and the second MME is the MME that the UE is currently registering with. Wherein, the sharing method includes the following steps 101 to 103, which are described in detail as follows.

[0040] Step 101: Obtain the globally unique temporary identifier GUTI of the user equipment UE in the registered network.

[0041] In the embodiment of the present invention, the UE may be a mobile phone terminal, or other equipment capable of sending or receiving wireless signals, such as a personal digital assistant (PDA), a wireless modem, a wireless communication device, a handheld device, a laptop Computers, cordless phones, wireless local loop (WLL) stations, CPE or Mifi capable of converting mobile signals into wifi signals, smart home appliances, or other devices that can communicate with mobile communication ne...

[0053] Such as figure 2 As shown, the second embodiment of the present invention provides a UE context sharing method applied to the second MME, including the following steps 201 to 205, which are described in detail as follows.

[0054] Step 201: Acquire a request message sent by a UE and carrying at least a GUTI of the UE in a registered network.

[0055] Wherein, the request message obtained in step 201 is a tracking area update TAU request message, a service request SR message or an attach request message. Specifically, according to the TAU request message sent by the UE, the location area registered by the UE in the CN can be changed; according to the SR message sent by the UE, the connection relationship between the UE and the CN can be re-established; , the UE can be re-registered in the current serving network.

[0056] Since the request message obtained by the second MME carries the GUTI of the UE in the registered network, it can obtain the GUTI of the UE in the r...

[0071] Such as image 3 As shown, the third embodiment of the present invention provides a UE context sharing method applied to the second MME, including the following steps 301 to 305, which are described in detail below.

[0072] Step 301: Obtain a request message sent by the UE and carrying at least the GUTI of the UE in the registered network.

[0073] Wherein, the request message obtained in step 301 is a tracking area update TAU request message, a service request SR message or an attach request message. Specifically, according to the TAU request message sent by the UE, the location area registered by the UE in the CN can be changed; according to the SR message sent by the UE, the connection relationship between the UE and the CN can be re-established; , the UE can be re-registered in the current serving network.

[0074] Since the request message received by the second MME carries the GUTI of the UE in the registered network, it can acquire the GUTI of the UE in the re...

Abstract

The present invention provides a UE context sharing method and device, wherein the UE context sharing method includes: obtaining the GUTI of the UE in the registered network, if the PLMN ID in the GUTI is the MFGPLMN ID shared by the NH network, Determining that the network in which the UE is registered is an NH network, obtaining a registered NHN ID of the UE, and obtaining context information of the UE in the registered network according to the NHN ID and GUTI. With the help of the solution of the present invention, even if the network in which the UE has registered is an NH network, the context information of the UE in the registered network can be obtained.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a UE context sharing method and device. Background technique [0002] MulteFire is a new LTE (Long Term Evolution)-based wireless access technology that can operate independently in unlicensed spectrum without the use of licensed band carriers. MulteFire extends LTE to unlicensed spectrum. The physical layer introduces a Listen Before Talk (LBT, Listen Before Talk) mechanism similar to WiFi carrier sense technology to achieve fair competition for air interface resources with unlicensed band devices. [0003] MulteFire can be used in the existing 3GPP network architecture and interface with the existing 3GPP core network to provide traditional mobile network operators with the capacity, coverage and data offload brought by unlicensed spectrum, and improve traditional operators' service life by supplementing licensed spectrum or hotspots service quality. [0004] A...
