Abstract

Embodiments of the present invention provide a capability matching method, an apparatus, and a system. The method includes: before a UE initiates a random access process, identifying, by the UE, a capability of a network side device, and when the UE identifies that the network side device is a network side device that does not support LC-MTC, reselecting, by the UE, to access another network side device. By means of the capability matching method, the apparatus, and the system provided in the embodiments of the present invention, a problem that a capability mismatch occurs between a UE and a network side device is avoided, and a waste of authorized resources, extra power consumption of a UE, and an interruption of data transmission are avoided.

First claim

What is claimed is:

1 . A capability matching method, comprising:
before user equipment UE initiates a random access process, identifying, by the UE, a capability of a network side device; and when the UE identifies that the network side device is a network side device that does not support low cost machine type communication LC-MTC, reselecting, by the UE, to access another network side device.

2 . The method according to claim 1 , wherein the identifying, by the UE, a capability of a network side device comprises:
determining, by the UE, whether a system information block SIB in a physical downlink shared channel PDSCH carries capability indication information, wherein the capability indication information comprises any one or a combination of the following: a capability indication that the network side device supports LC-MTC; a version number of the network side device; an access type block parameter, wherein the access type block parameter comprises an LC-MTC type and an access parameter corresponding to the LC-MTC type; an enhanced access type block parameter, wherein the enhanced access type block parameter comprises an LC-MTC type and an access parameter corresponding to the LC-MTC type; a random access channel RACH channel configuration message, wherein the RACH channel configuration message comprises LC-MTC type dedicated configuration information; and a physical random access channel PRACH channel configuration message, wherein the PRACH channel configuration message comprises LC-MTC type dedicated configuration information.

3 . The method according to claim 1 , before the reselecting, by the UE, to access another network side device, further comprising:
identifying, by the UE, the network side device as a forbidden network side device.

4 . A capability matching method, comprising:
generating, by a network side device, capability indication information; and sending, by the network side device, the capability indication information to user equipment UE, so that when identifying that the network side device is a network side device that does not support low cost machine type communication LC-MTC, the UE reselects to access another network side device.

5 . The method according to claim 8 , wherein the capability indication information is carried in a system information block SIB, and the capability indication information comprises any one or a combination of the following:
a capability indication that the network side device supports LC-MTC; a version number of the network side device; an access type block parameter, wherein the access type block parameter comprises an LC-MTC type and an access parameter corresponding to the LC-MTC type; an enhanced access type block parameter, wherein the enhanced access type block parameter comprises an LC-MTC type and an access parameter corresponding to the LC-MTC type; a random access channel RACH channel configuration message, wherein the RACH channel configuration message comprises LC-MTC type dedicated configuration information; and a physical random access channel PRACH channel configuration message, wherein the PRACH channel configuration message comprises LC-MTC type dedicated configuration information.

6 . The method according to claim 4 , further comprising:
sending, by the network side device, a setup request message or configuration update message to a core network device, wherein the setup request message or configuration update message carries an identifier of a network side device that supports LC-MTC, so that the core network device saves the identifier of the network side device that supports LC-MTC, and sends reselection configuration information comprising the identifier to the UE.

7 . User equipment, comprising:
a processor, configured to: before a random access process is initiated, identify a capability of a network side device; and the processor, is further configured to: when the identification module identifies that the network side device is a network side device that does not support low cost machine type communication LC-MTC, reselect to access another network side device.

8 . The user equipment according to claim 7 , wherein the processor is configured to:
determine whether a system information block SIB in a physical downlink shared channel PDSCH carries capability indication information, wherein the capability indication information comprises any one or a combination of the following: a capability indication that the network side device supports LC-MTC; a version number of the network side device; an access type block parameter, wherein the access type block parameter comprises an LC-MTC type and an access parameter corresponding to the LC-MTC type; an enhanced access type block parameter, wherein the enhanced access type block parameter comprises an LC-MTC type and an access parameter corresponding to the LC-MTC type; a random access channel RACH channel configuration message, wherein the RACH channel configuration message comprises LC-MTC type dedicated configuration information; and a physical random access channel PRACH channel configuration message, wherein the PRACH channel configuration message comprises LC-MTC type dedicated configuration information.

9 . The user equipment according to claim 7 , wherein the processor is further configured to:
before reselecting to access another network side device, identify the network side device as a forbidden network side device.

10 . A network side device, comprising:
a processor, configured to generate capability indication information; and a transmitter, configured to send the capability indication information to user equipment UE, so that when identifying that the network side device is a network side device that does not support low cost machine type communication LC-MTC, the UE reselects to access another network side device.

11 . The network side device according to claim 10 , wherein the capability indication information is carried in a system information block SIB, and the capability indication information comprises any one or a combination of the following:
a capability indication that the network side device supports LC-MTC; a version number of the network side device; an access type block parameter, wherein the access type block parameter comprises an LC-MTC type and an access parameter corresponding to the LC-MTC type; an enhanced access type block parameter, wherein the enhanced access type block parameter comprises an LC-MTC type and an access parameter corresponding to the LC-MTC type; a random access channel RACH channel configuration message, wherein the RACH channel configuration message comprises LC-MTC type dedicated configuration information; and a physical random access channel PRACH channel configuration message, wherein the PRACH channel configuration message comprises LC-MTC type dedicated configuration information.

12 . The network side device according to claim 11 , wherein the transmitter is further configured to:
send a setup request message or configuration update message to a core network device, wherein the setup request message or configuration update message carries an identifier of a network side device that supports LC-MTC, so that the core network device saves the identifier of the network side device that supports LC-MTC, and sends reselection configuration information comprising the identifier to the UE.

13 . A capability matching method, comprising:
receiving, by a first network side device, a measurement report message sent by user equipment UE that supports low cost machine type communication LC-MTC; and performing
