Problems solved by technology

However, this method means that during a call of the user, if the user leaves the private cell for a short time (such as going to the balcony or yard in the middle), the UE is switched to the macro cell at this time, and when the user returns to the private cell When the effective coverage range (such as returning to the house), the call cannot be switched back to the private cell, but can only continue to receive the service of the macro cell until the call ends
That means that even if you return to the coverage of private cells, you will not get tariffs and performance discounts from private cells, which is a loss for users

Embodiment 1

[0074] Embodiment 1: Transfer private network information such as E-UTRAN internal handover Figure 9 As shown, the private cell network and the macro cell network both belong to E-UTRAN, and the private cell network and the macro cell network are the same MME and SGW, and the internal handover at the CN side includes the following steps:

[0075] Step 1: The private cell network makes a handover decision;

[0076] Step 2: The private cell network sends a relocation request message to the MME, wherein the relocation request message carries private network information;

[0077] Step 3: After receiving the relocation request message of the private network, the MME sends a relocation request message to the macro cell network, wherein the relocation request message carries information of the private network;

[0078] Step 4: After receiving the relocation request sent by the MME, the macro cell network sends a relocation request ACK (Acknowledge, response) to the MME;

[0079] S...

Embodiment 2

[0088] Embodiment 2 When switching between other 3GPP RATs, transfer private network information such as Figure 10 As shown, the private cell network can be E-UTRAN, the macro cell network can be UTRAN or GERAN, or the private cell network is UTRAN, and the macro cell network is E-UTRAN, wherein if the private cell network is E-UTRAN, the macro cell network In the handover of UTRAN, the private network cell can transmit the private network information to the macro cell network during the handover preparation stage. For details, see Figure 10 Steps 2, 3, 4, and 5, or only in steps 2, 3, and 5, can also transmit private cell network information to the macro cell network during the handover execution phase. For details, see Figure 11 Steps 3, 3a, 3b of:

[0089] in Figure 10 Steps 2, 3, 4, and 5 are specifically:

[0090] Step 2: The private cell network (source eNodeB) sends a handover request message to the source mobility management entity MME, wherein the message in th...

Abstract

The invention relates to the field of wireless communication, and discloses a method and a device for switching between a macro cell and a private cell, wherein the switching method comprises the following steps that: a macro network acquires information of a private network; according to the information, the macro network configures measurement control information of a terminal; and according to the measurement control information, the switching from the macro network to the private network is executed. The method and the device can realize that when the UE outside the private cell returns to the covering range of the private cell, that the UE can be quickly switched to the private cell so as to enjoy better service and that the higher performance-price ratio brought by the private cell.

Description

technical field [0001] The invention relates to the field of wireless communication, in particular to a technology for switching between a macro cell and a private cell. Background technique [0002] Femto cell / Home eNB / CSG cell / AP can be collectively referred to as a private cell, which means a class of network side nodes that are similar in function to macro cells and macro base stations (can provide wireless access services for terminals), but have differences . The private cell radio access technology (RAT) may be: LTE, UTRAN, GERAN, HSPA+, CDMA, WiMAX, etc. [0003] Private communities have the following characteristics: [0004] 1. The coverage area is small; [0005] 2. Mainly indoor coverage; [0006] 3. Compared with the macro base station, its equipment cost is lower; [0007] 4. Its ownership often does not belong to mobile network operators, but to private individuals, family owners or certain non-mobile network companies, such as entertainment business comp...
