Embodiment 1

[0107] What is mainly described in this embodiment is the method flow of the MME assigning a fake IP address, such as Figure 11 shown, including the following steps:

[0108] Step S1102, the UE sends an attach request message to the MME through the eNodeB, the request message carries parameters such as the IMSI and the UE network capability; the message may also carry an indication that an IP address is not allocated, and the indication may also be sent through a short message or The control plane transmits small data or special APN to represent;

[0109] Step S1104, the MME sends a location update request message to the HSS, and the location update request message carries the update type and the MME address;

[0110] Step S1106, the HSS returns a location update response message to the MME, the response message carries user subscription data, and the user subscription data includes APN, default bearer QoS, whether to allow short messages to be transmitted through the PS net...

Embodiment 2

[0115] In this embodiment, the main description is that the MME allocates a fake IP address and then notifies the PGW of the method flow, as shown in Figure 12 shown, including the following steps:

[0116] Step S1202, the UE sends an attach request message to the MME through the eNodeB, the request message carries parameters such as the IMSI and the UE network capability; the message may also carry an indication that an IP address is not allocated, and the indication may also be sent through a short message or The control plane transmits small data or special APN to represent;

[0117] Step S 1204, the MME sends a location update request message to the HSS, the location update request message carries the update type and the MME address;

[0118] Step S1206, the HSS returns a location update response message to the MME, the response message carries user subscription data, wherein the user subscription data includes APN, default bearer QoS, whether to allow short messages to ...

Embodiment 3

[0127] What is mainly described in this embodiment is the method flow of the PGW assigning a fake IP address, such as Figure 13 shown, including the following steps;

[0128]Step S1302, the UE sends an attach request message to the MME through the eNodeB, the request message carries parameters such as IMSI and UE network capabilities; the message may also carry an indication that an IP address is not allocated, and the indication may also be sent through a short message or The control plane transmits small data or special APN to represent;

[0129] Step S1304, the MME sends a location update request message to the HSS, and the location update request message carries the update type and the MME address;

[0130] Step S1306, the HSS returns a location update response message to the MME, the response message carries user subscription data, the user subscription data includes APN, default bearer QoS, whether to allow short messages to be transmitted through the PS network, or sm...

Abstract

The invention discloses an address allocation method and device. The method comprises the steps that a network element of a core network judges whether a user plane channel with the core network needs to be established for the service currently executed by UE or not; if a judging result is negative, the network element of the core network allocates a false IP address for the UE, wherein the false IP address has a format of an IP address, but the UE cannot carry out data transmission based on the false IP address. The address allocation method and device solves the technical problem that IP resources are wasted due to the fact that user planes for carrying need to be established for all accessed networks of the UE in the prior art, and achieves the technical effect that the utilization rate of the IP resources are improved.

Description

technical field [0001] The present invention relates to the communication field, in particular to an address allocation method and device. Background technique [0002] With the sudden emergence of World Interoperability for Microwave Access (WiMax), the third generation mobile communication system must improve its network performance and reduce network Construction and operating costs. Therefore, the standardization working group of the 3rd Generation Partnership Project (3rd Generation Partnership Project, referred to as 3GPP) is currently working on researching packet switching core network (Packet Switch Core, referred to as PS Core) and GSM wireless access Network (Universal Mobile Telecommunication System RadioAccess Network, referred to as UTRAN) evolution, this research topic is called System Architecture Evolution (referred to as SAE), the purpose is to make the evolved packet network (Evolved Packet Core, referred to as EPC) can Provide higher transmission rate, ...
