Embodiment 1

[0045] Embodiment 1 is applied to the application scenario where the HeNB GW is deployed, and mainly includes: if the network is configured with LIPA paging optimization, the paging message sent by the MME to the HeNB GW carries the HeNB identifier corresponding to the LIPA bearer. pass below Figure 4a This Example 1 is described in detail.

[0046] see Figure 4a , Figure 4a It is a flowchart provided by Embodiment 1 of the present invention. Such as Figure 4a As shown, the process may include the following steps:

[0047] Step 401a, when the L-GW receives the downlink data, if the downlink data is for LIPA, the L-GW sends the downlink data to the S-GW.

[0048] In this step 401a, if applied to the network architecture of R-10, the L-GW sends the first downlink data to the S-GW, and other data is cached in the L-GW. If applied to other network architectures, the downlink data is sent according to the requirements of the network architecture.

[0049] In step 402a, t...

Embodiment 2

[0062] The second embodiment is also applied to the application scenario where HeNB GW is deployed, which mainly includes: if the network is configured with LIPA paging optimization, the paging message sent by MME to HeNB GW carries parameters of the HeNB. In this way, the HeNB GW can determine the corresponding HeNB according to the parameters in the paging message. Embodiment 2 is described in detail below:

[0062] The second embodiment is also applied to the application scenario where HeNB GW is deployed, which mainly includes: if the network is configured with LIPA paging optimization, the paging message sent by MME to HeNB GW carries parameters of the HeNB. In this way, the HeNB GW can determine the corresponding HeNB according to the parameters in the paging message. Embodiment 2 is described in detail below:

[0063] see Figure 5a , Figure 5a The flow chart provided for Embodiment 2 of the present invention. As shown in Figure 5, the process may include the following steps:

[0064] Steps 501a to 502a are similar to steps 401a to 402a and will not be repeated here.

[0065] Step 503a, after the MME determines that this paging is a paging that supports LIPA according to the bearer identifier in the paging message, determine the paging message according to the corresponding relationship between the bearer identifier and the IP address of the LGW saved when the UE establi...

Abstract

The present invention provides paging optimization methods. One of the methods is applied to a network including a HeNB GW and includes that: if LIPA paging optimization is configured in the network, transmitting, by a MME, to the HeNB GW a paging message including a HeNB ID corresponding to a LIPA bearer. By the present invention, LIPA paging optimization can be realized in the scenario in which the HeNB GW is configured or in network architecture supported by R-11.

Description

technical field [0001] The invention relates to wireless communication technology, in particular to a paging optimization method. Background technique [0002] see figure 1 , figure 1 A system architecture diagram of an existing System Architecture Evolution (SAE) is shown. exist figure 1 Among them, a user equipment (UE) 101 is a terminal device for receiving data. Evolved Universal Terrestrial Radio Access Network (E-UTRAN) 102 is a radio access network including macro base stations (eNodeBs / NodeBs) that provide UEs with an interface to access the radio network. Mobility Management Entity (MME) 103 is responsible for managing UE's mobility context, session context and security information. Serving Gateway (SGW) 104 mainly provides user plane functions, and MME 103 and SGW 104 may be in the same physical entity. The packet data network gateway (PGW) 105 is responsible for functions such as charging and lawful interception, and may also be in the same physical entity a...
