Problems solved by technology

[0023] The present invention is proposed to solve the problem that the maximum traffic and billing of each group cannot be effectively limited due to the inability to allocate the MTC terminals of the same group to the same PGW. Therefore, the main purpose of the present invention is to provide a PGW Selecting methods and network elements for mobility management to address at least one of the above problems

Embodiment 1

[0079] Figure 4 It is a flow chart according to Embodiment 1 of the present invention. In the embodiment, the MME selects a suitable PGW for the MTC UE according to the group ID in the M2M subscription data. Such as Figure 4 As shown, in this embodiment, selecting a PGW for the MTC UE mainly includes the following steps:

[0080] Step S401, the MTC UE initiates an attach request to the MME;

[0081] Step S402, the MME sends a location update request to the HSS, and the location update request carries the identity of the above-mentioned MTC UE;

[0082] Step S403, the HSS sends a location update response to the MME, and downloads subscription data to the MME at the same time;

[0083] In this step, the HSS can know that the MTC UE is an MTC terminal according to the identity of the MTC UE, and can also know the group to which the MTC UE belongs. When downloading the subscription data to the MME, the subscription data includes the The group ID and M2M subscription data of ...

Embodiment 2

[0094] Figure 5 It is a flow chart according to Embodiment 2 of the present invention. In this embodiment, the MME selects a suitable PGW for the MTC user according to the group ID reported by the MTC UE. Such as Figure 5 As shown, in this embodiment, MME allocates PGW for MTC UE mainly includes the following steps:

[0095] Step S501, the MTC UE initiates an attach request to the MME, and the attach request carries an M2M indication and a group identifier of the MTC group to which the MTC UE belongs;

[0096] Wherein, the M2M indication is used to indicate that the UE is an MTC terminal; the group identifier is used to indicate the MTC group to which the MTC UE belongs.

[0097] If the group identifier can indicate that the UE is an MTC terminal, the M2M indication may not be carried.

[0098] Step S502, MME acquires the group ID and M2M identity of the MTC UE, and sends a location update request to the HSS;

[0099] Step S503, the HSS sends a location update response t...

Embodiment approach 1

[0114] Implementation mode one: Figure 9 is a schematic structural diagram of the distribution module 62 of this embodiment, as Figure 9 As shown, in this embodiment, the allocation module 62 mainly includes: a storage unit 920 and an allocation unit 922 . Wherein, the storage unit 920 is used to store the preset correspondence between the group ID and the PGW; the allocation unit 922 is used to allocate the PGW corresponding to the group ID of the MTC group acquired by the acquisition module 60 to the MTC terminal. Through this embodiment, the mobility management network element can allocate the same PGW to the same group ID according to the corresponding relationship stored locally, thereby improving the efficiency of allocating PGWs.

Abstract

The invention discloses a selection method of a packet data network gateway and a mobility management network element, wherein the selection method of the packet data network gateway comprises the following steps that the mobility management network element acquires a group mark of an MTC (Mobile Talk Club) group to which an MTC terminal is attributed; and the mobility management network element distributes a same packet data network gateway to the MTC terminal with the same group mark. Through the invention, the total flow can be controlled according to groups, and accounting is realized according to the groups.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to a method for selecting a packet data network gateway and a mobility management network element. Background technique [0002] Machine-to-machine (M2M) communication, also known as Machine Type Communication (MTC), is most typically the communication between a terminal and an application server, and the terminal is called MTC A terminal (MTC User Equipment, MTC UE for short), and an application server are called an MTC server (MTC Server). The behavior of the terminal in the M2M communication is restricted by the service contract data, and the network manages the terminal in the M2M communication according to the service contract data. [0003] Under 2G / 3G / LTE access, the M2M communication mainly uses the Packet Service (PS) network as the underlying bearer network to realize the service layer communication between the MTC terminal and the MTC server. figure 1 It is a sch...
