Problems solved by technology

[0016] However, in the prior art, the bearer established by the UE must use the SGi or Gi interface, because in the end only the PDN GW or GGSN can determine the type of IP address allocated to the UE and allocate this type of IP address to the UE
[0017] The current 3GPP specification puts forward new requirements for version 9 (R9) home base stations (HomeeNodeB or Home NodeB) in the TS22.220 standard, pointing out that UEs with IP capabilities should be able to connect with IP-capable UEs in the home The devices are connected to each other, and in the home network, the PDN GW or GGSN in the core network will not be used, so the IP address cannot be assigned to the UE

Embodiment 1

[0117] see image 3 The UE Requested PDN Connectivity (UE Requested PDN Connectivity) process provided by the embodiment of the present invention specifically includes steps:

[0118] 1. If the UE needs to initiate a PDN connection, the UE sends a PDN Connectivity Request message to the HeNB, and the HeNB forwards the PDN Connectivity Request message to the Mobility Management Entity (MME).

[0119] The PDN Connectivity Request message includes: access point name (APN), PDN Type, protocol configuration options (Protocol Configuration Options) and request type (Request Type).

[0120] Both the APN and Request Type carried in the PDN Connectivity Request can be used to indicate the type information of the local network that the UE requests to access, but if the UE is allowed to access multiple local networks of the same type APN is required to indicate which specific local network is entered.

[0121] If the newly established PDN connection of the UE is to the home network, th...

Embodiment 2

[0155] see Figure 4 , the Attach process provided by the embodiment of the present invention specifically includes steps:

[0156] 1. The UE initiates an attach process, and sends an Attach Request (Attach Request) message to the HeNB.

[0157]The Attach Request message includes: International Mobile Subscriber Identity (IMSI) or old Globally Unique (User) Temporary Identity (GUTI, Globally Unique Temporary Identity), last visited TAI (if available), UE's Core network capability (UE Core NetworkCapability), UE's special discontinuous reception (DRX, Discontinuous Reception) parameters, PDN type (PDN Type), protocol configuration options (Protocol Configuration Options), encrypted transmission selection flag (Ciphered Options Transfer Flag), Attach type (Attach Type), key identifier (KSIASME), non-access stratum (NAS, Non-Access Stratum) sequence number (NAS sequencenumber), non-access stratum message authentication code (NAS-MAC, Message Authentication Code), Additional GUT...

Embodiment 3

[0200] see Figure 5 The PDN connection (Activate PDP Context) process requested by the UE provided in the embodiment of the present invention specifically includes steps:

[0201] 1. If the UE needs to initiate a PDN connection, the UE sends an Activate PDP Context Request (Activate PDP Context Request) message to the HNB, and the HNB forwards the Activate PDP Context Request message to the Serving General Packet Radio Service Support Node (SGSN).

[0202] It should be noted that there may be a home base station gateway (HNB GW) between the HNB and the SGSN. If there is an HNB GW, the HNB GW transparently transmits messages between the UE and the SGSN, that is, in this process, all messages are transparent to the HNB GW, that is, the HNB GW does not interpret the information between the UE and the SGSN. The message transmitted between UE and SGSN is only to forward the message between UE and SGSN.

[0203]In addition, by activating the packet data protocol context request (...

Abstract

The invention discloses an IP address allocation method and a system, which are used for determining the types of IP addresses allocated to user equipment (UE) by local networks through a user mobile control management entity in the PDNGW (Public Data Network Gate Way) and GGSN (Gateway GPRS Support Node) local networks without core networks and allocates the IP addresses of the type to the user equipment (UE). The IP address allocation method comprises the following steps that the user mobile control management entity requests the accessed information of the local networks according to the user equipment (UE) to indicate a home NodeB to access the user equipment (UE) to the local networks through establishing the radio bearers of the local networks; the user mobile control management entity determines the types of the IP addresses allocated to the user equipment (UE) by the local networks and indicates the user equipment (UE) to acquire the IP address of the type from the home NodeB;and the home NodeB allocates the information of the IP addresses according to a request sent by the user equipment (UE) and allocates the IP addresses for the user equipment (UE).

Description

technical field [0001] The invention relates to the field of communication technology, in particular to an Internet Protocol (IP, Internet Protocol) address allocation method and system. Background technique [0002] In the Evolved Packet System (EPS, Evolved Packet System), version 4 of the Internet Protocol (IPv4) and version 6 of the Internet Protocol (IPv6) are supported. [0003] The solution for obtaining an IP address by a user equipment (UE) in the prior art includes: [0004] The UE initiates the establishment of the PDN connection of the SGi interface or the Gi interface; [0005] The UE sends the type information of the IP address requested to be allocated to the network side, that is, the UE requests the network side to allocate an IPv4 address and / or an IPv6 address. [0006] After receiving the type information of the IP address requested by the UE, the user mobility control management entity on the network side may further modify the type information of the ...
