Embodiment 1

[0054] Please refer to figure 1 , Embodiment 1 of the present invention is:

[0055] A kind of method that realizes MME pool provided by the present invention comprises the following steps:

[0056] Presetting multiple mobility management devices and multiple address sets; the mobility management devices are in one-to-one correspondence with the address sets;

[0057] Initializing the mobility management device; recording and saving an address set corresponding to the mobility management device in a configuration file of the mobility management device;

[0058] The mobile terminal sends a request message to multiple mobility management devices through the base station and the core network;

[0059] Obtaining the address of the base station; reading the configuration file of the mobility management device;

[0060] judging whether the address of the base station belongs to the address set in the configuration file;

[0061] If yes, the mobility management device performs si...

Embodiment 2

[0064] The difference between Embodiment 2 and Embodiment 1 is that a method for implementing an MME pool further includes:

[0065] The base station establishes a connection with the core network based on the S1 interface protocol; the S1 interface protocol performs data transmission based on the SCTP protocol; the mobility management device performs signaling processing on the request message to obtain a first message;

[0066] Send the first message to the server; the server responds to the first message to obtain a response message; according to the address of the base station, send the response message to the base station; the mobile terminal receives The response message sent by the base station.

[0067] As can be seen from the above description, the standard S1 interface protocol is used to establish a connection, which has wide applicability; the server responds to the request message, and the response message obtained is sent to the mobile terminal through the core n...

Embodiment 3

[0068] Please refer to figure 2 , the third embodiment of the present invention is:

[0069] The preset module presets multiple mobility management devices and multiple address sets; the mobility management devices correspond to the address sets one by one, and sends the correspondence between the mobility management devices and the address sets to recording module; the initialization module initializes the mobility management device, and sends the data of the initialized mobility management device to the recording module; uses the recording module to record and save the configuration file of the mobility management device with the mobile The address set corresponding to the mobility management device, and send the configuration file to the reading unit; the first sending module is used for the mobile terminal to send the request message to a plurality of the mobility management devices through the base station and the core network, and send the base station The information ...

Abstract

The invention relates to the technical field of mobile communication and particularly relates to a method and a system for realizing an MME (Mobile Management Entity) pool. The function of the MME pool is realized according to the following steps: presetting a plurality of mobile management devices and a plurality of address sets, wherein the mobile management devices are corresponding to the address sets one by one; sending a request message to the mobile management devices by a mobile terminal through a base station and a core network; performing signaling treatment on the request message by the mobile management device corresponding to the address set to which the address of the base station belongs. According to the invention, a corresponding request message is treated by one mobile management device, so as to prevent a LTE (Long Term Evolution) user from failing to normally communicate under the influence of disordered message treatment resulting from the operation of treating one request message by the plurality of mobile management devices. According to the method, the simultaneous operation of the plurality of mobile management devices in one core network can be realized, namely, the function of the MME pool is realized and the MME pool networking cost is lowered.

Description

technical field [0001] The invention relates to the technical field of mobile communication, in particular to a method and system for realizing an MME pool. Background technique [0002] The server management equipment (MME, Mobility Management Entity) is a key control node of the 3GPP protocol LTE access network, and is an entity for signaling processing. Its main functions are to support NAS (non-access stratum) signaling and its security, management of tracking area list, selection of SGSN during handover to 2G / 3G access system, user authentication, roaming control and bearer Management, mobility management between core network nodes of different 3GPP access networks, and control and execution of paging retransmission of mobile terminals. [0003] The MME nodes in the MME pool will share the load of all users in the service area of ​​the pool. As long as the user terminal stays in the pool service area, it will usually be attached to the same MME node. If the MME is un...
